It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible. ## Features of Ruby * Simple Syntax * **Normal** Object-oriented Features (e.g. class, method calls) * **Advanced** Object-oriented Features (e.g. mix-in, singleton-method) * Operator Overloading * Exception Handling * Iterators and Closures * Garbage Collection * Dynamic Loading of Object Files (on some architectures) * Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#label-Platform+Maintainers ## How to get Ruby For a complete list of ways to install Ruby, including using third-party tools like rvm, see: https://www.ruby-lang.org/en/downloads/ ### Git The mirror of the Ruby source tree can be checked out with the following command: $ git clone https://github.com/ruby/ruby.git There are some other branches under development. Try the following command to see the list of branches: $ git ls-remote https://github.com/ruby/ruby.git You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source) if you are a committer. ### Subversion Stable branches for older Ruby versions can be checked out with also the following command: $ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby Try the following command to see the list of branches: $ svn ls https://svn.ruby-lang.org/repos/ruby/branches/ ## Ruby home page https://www.ruby-lang.org/ ## Mailing list There is a mailing list to discuss Ruby. To subscribe to this list, please send the following phrase: subscribe in the mail body (not subject) to the address [ruby-talk-request@ruby-lang.org]. [ruby-talk-request@ruby-lang.org]: mailto:ruby-talk-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe ## How to compile and install 1. If you want to use Microsoft Visual C++ to compile Ruby, read [win32/README.win32](win32/README.win32) instead of this document. 2. Run `./autogen.sh` to generate configure, when you build the source checked out from the Git repository. 3. Run `./configure`, which will generate `config.h` and `Makefile`. Some C compiler flags may be added by default depending on your environment. Specify `optflags=..` and `warnflags=..` as necessary to override them. 4. Edit `include/ruby/defines.h` if you need. Usually this step will not be needed. 5. Remove comment mark(`#`) before the module names from `ext/Setup` (or add module names if not present), if you want to link modules statically. If you don't want to compile non static extension modules (probably on architectures which do not allow dynamic loading), remove comment mark from the line "`#option nodynamic`" in `ext/Setup`. Usually this step will not be needed. 6. Run `make`. * On Mac, set RUBY\_CODESIGN environment variable with a signing identity. It uses the identity to sign `ruby` binary. See also codesign(1). 7. Optionally, run '`make check`' to check whether the compiled Ruby interpreter works well. If you see the message "`check succeeded`", your Ruby works as it should (hopefully). 8. Run '`make install`'. This command will create the following directories and install files into them. * `${DESTDIR}${prefix}/bin` * `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}` * `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}` * `${DESTDIR}${prefix}/lib` * `${DESTDIR}${prefix}/lib/ruby` * `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}` * `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}` * `${DESTDIR}${prefix}/lib/ruby/site_ruby` * `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}` * `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}` * `${DESTDIR}${prefix}/lib/ruby/vendor_ruby` * `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}` * `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}` * `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}` * `${DESTDIR}${prefix}/share/man/man1` * `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system` If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'. **NOTE**: teeny of the API version may be different from one of Ruby's program version You may have to be a super user to install Ruby. If you fail to compile Ruby, please send the detailed error report with the error log and machine/OS type, to help others. Some extension libraries may not get compiled because of lack of necessary external libraries and/or headers, then you will need to run '`make distclean-ext`' to remove old configuration after installing them in such case. ## Copying See the file [COPYING](COPYING). ## Feedback Questions about the Ruby language can be asked on the Ruby-Talk mailing list (https://www.ruby-lang.org/en/community/mailing-lists) or on websites like (https://stackoverflow.com). Bugs should be reported at https://bugs.ruby-lang.org. Read [HowToReport] for more information.

Note that each entry is kept so brief that no reason behind or reference information is supplied with. For a full list of changes with all sufficient information, see the ChangeLog file or Redmine (e.g. `https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER`). ## Language changes * Keyword arguments are now separated from positional arguments. Code that resulted in deprecation warnings in Ruby 2.7 will now result in ArgumentError or different behavior. [[Feature #14183]] * Procs accepting a single rest argument and keywords are no longer subject to autosplatting. This now matches the behavior of Procs accepting a single rest argument and no keywords. [[Feature #16166]] ```ruby pr = proc{|*a, **kw| [a, kw]} pr.call([1]) # 2.7 => [[1], {}] # 3.0 => [[[1]], {}] pr.call([1, {a: 1}]) # 2.7 => [[1], {:a=>1}] # and deprecation warning # 3.0 => [[[1, {:a=>1}]], {}] ``` * Arguments forwarding (`...`) now supports leading arguments. [[Feature #16378]] ```ruby def method_missing(meth, ...) send(:"do_#{meth}", ...) end ``` * Pattern matching (`case/in`) is no longer experimental. [[Feature #17260]] * One-line pattern matching is redesigned. [EXPERIMENTAL] * `=>` is added. It can be used like a rightward assignment. [[Feature #17260]] ```ruby 0 => a p a #=> 0 {b: 0, c: 1} => {b:} p b #=> 0 ``` * `in` is changed to return `true` or `false`. [[Feature #17371]] ```ruby # version 3.0 0 in 1 #=> false # version 2.7 0 in 1 #=> raise NoMatchingPatternError ``` * Find-pattern is added. [EXPERIMENTAL] [[Feature #16828]] ```ruby case ["a", 1, "b", "c", 2, "d", "e", "f", 3] in [*pre, String => x, String => y, *post] p pre #=> ["a", 1] p x #=> "b" p y #=> "c" p post #=> [2, "d", "e", "f", 3] end ``` * Endless method definition is added. [EXPERIMENTAL] [[Feature #16746]] ```ruby def square(x) = x * x ``` * Interpolated String literals are no longer frozen when `# frozen-string-literal: true` is used. [[Feature #17104]] * Magic comment `shareable_constant_value` added to freeze constants. See {Magic Comments}[rdoc-ref:doc/syntax/comments.rdoc@Magic+Comments] for more details. [[Feature #17273]] * A {static analysis}[rdoc-label:label-Static+analysis] foundation is introduced. * {RBS}[rdoc-label:label-RBS] is introduced. It is a type definition language for Ruby programs. * {TypeProf}[rdoc-label:label-TypeProf] is experimentally bundled. It is a type analysis tool for Ruby programs. * Deprecation warnings are no longer shown by default (since Ruby 2.7.2). Turn them on with `-W:deprecated` (or with `-w` to show other warnings too). [[Feature #16345]] * $SAFE and $KCODE are now normal global variables with no special behavior. C-API methods related to $SAFE have been removed. [[Feature #16131]] [[Feature #17136]] * yield in singleton class definitions in methods is now a SyntaxError instead of a warning. yield in a class definition outside of a method is now a SyntaxError instead of a LocalJumpError. [[Feature #15575]] * When a class variable is overtaken by the same definition in an ancestor class/module, a RuntimeError is now raised (previously, it only issued a warning in verbose mode). Additionally, accessing a class variable from the toplevel scope is now a RuntimeError. [[Bug #14541]] * Assigning to a numbered parameter is now a SyntaxError instead of a warning. ## Command line options ### `--help` option When the environment variable `RUBY_PAGER` or `PAGER` is present and has a non-empty value, and the standard input and output are tty, the `--help` option shows the help message via the pager designated by the value. [[Feature #16754]] ### `--backtrace-limit` option The `--backtrace-limit` option limits the maximum length of a backtrace. [[Feature #8661]] ## Core classes updates Outstanding ones only. * Array * The following methods now return Array instances instead of subclass instances when called on subclass instances: [[Bug #6087]] * Array#drop * Array#drop_while * Array#flatten * Array#slice! * Array#slice / Array#[] * Array#take * Array#take_while * Array#uniq * Array#* * Can be sliced with Enumerator::ArithmeticSequence ```ruby dirty_data = ['--', 'data1', '--', 'data2', '--', 'data3'] dirty_data[(1..).step(2)] # take each second element # => ["data1", "data2", "data3"] ``` * Binding * Binding#eval when called with one argument will use "(eval)" for `__FILE__` and 1 for `__LINE__` in the evaluated code. [[Bug #4352]] [[Bug #17419]] * ConditionVariable * ConditionVariable#wait may now invoke the `block`/`unblock` scheduler hooks in a non-blocking context. [[Feature #16786]] * Dir * Dir.glob and Dir.[] now sort the results by default, and accept the `sort:` keyword option. [[Feature #8709]] * ENV * ENV.except has been added, which returns a hash excluding the given keys and their values. [[Feature #15822]] * Windows: Read ENV names and values as UTF-8 encoded Strings [[Feature #12650]] * Encoding * Added new encoding IBM720. [[Feature #16233]] * Changed default for Encoding.default_external to UTF-8 on Windows [[Feature #16604]] * Fiber * Fiber.new(blocking: true/false) allows you to create non-blocking execution contexts. [[Feature #16786]] * Fiber#blocking? tells whether the fiber is non-blocking. [[Feature #16786]] * Fiber#backtrace and Fiber#backtrace_locations provide per-fiber backtrace. [[Feature #16815]] * The limitation of Fiber#transfer is relaxed. [[Bug #17221]] * GC * GC.auto_compact= and GC.auto_compact have been added to control when compaction runs. Setting `auto_compact=` to true will cause compaction to occur during major collections. At the moment, compaction adds significant overhead to major collections, so please test first! [[Feature #17176]] * Hash * Hash#transform_keys and Hash#transform_keys! now accept a hash that maps keys to new keys. [[Feature #16274]] * Hash#except has been added, which returns a hash excluding the given keys and their values. [[Feature #15822]] * IO * IO#nonblock? now defaults to `true`. [[Feature #16786]] * IO#wait_readable, IO#wait_writable, IO#read, IO#write and other related methods (e.g. IO#puts, IO#gets) may invoke the scheduler hook `#io_wait(io, events, timeout)` in a non-blocking execution context. [[Feature #16786]] * Kernel * Kernel#clone when called with the `freeze: false` keyword will call `#initialize_clone` with the `freeze: false` keyword. [[Bug #14266]] * Kernel#clone when called with the `freeze: true` keyword will call `#initialize_clone` with the `freeze: true` keyword, and will return a frozen copy even if the receiver is unfrozen. [[Feature #16175]] * Kernel#eval when called with two arguments will use "(eval)" for `__FILE__` and 1 for `__LINE__` in the evaluated code. [[Bug #4352]] * Kernel#lambda now warns if called without a literal block. [[Feature #15973]] * Kernel.sleep invokes the scheduler hook `#kernel_sleep(...)` in a non-blocking execution context. [[Feature #16786]] * Module * Module#include and Module#prepend now affect classes and modules that have already included or prepended the receiver, mirroring the behavior if the arguments were included in the receiver before the other modules and classes included or prepended the receiver. [[Feature #9573]] ```ruby class C; end module M1; end module M2; end C.include M1 M1.include M2 p C.ancestors #=> [C, M1, M2, Object, Kernel, BasicObject] ``` * Module#public, Module#protected, Module#private, Module#public_class_method, Module#private_class_method, toplevel "private" and "public" methods now accept single array argument with a list of method names. [[Feature #17314]] * Module#attr_accessor, Module#attr_reader, Module#attr_writer and Module#attr methods now return an array of defined method names as symbols. [[Feature #17314]] * Module#alias_method now returns the defined alias as a symbol. [[Feature #17314]] * Mutex * `Mutex` is now acquired per-`Fiber` instead of per-`Thread`. This change should be compatible for essentially all usages and avoids blocking when using a scheduler. [[Feature #16792]] * Proc * Proc#== and Proc#eql? are now defined and will return true for separate Proc instances if the procs were created from the same block. [[Feature #14267]] * Queue / SizedQueue * Queue#pop, SizedQueue#push and related methods may now invoke the `block`/`unblock` scheduler hooks in a non-blocking context. [[Feature #16786]] * Ractor * New class added to enable parallel execution. See rdoc-ref:ractor.md for more details. * Random * `Random::DEFAULT` now refers to the `Random` class instead of being a `Random` instance, so it can work with `Ractor`. [[Feature #17322]] * `Random::DEFAULT` is deprecated since its value is now confusing and it is no longer global, use `Kernel.rand`/`Random.rand` directly, or create a `Random` instance with `Random.new` instead. [[Feature #17351]] * String * The following methods now return or yield String instances instead of subclass instances when called on subclass instances: [[Bug #10845]] * String#* * String#capitalize * String#center * String#chomp * String#chop * String#delete * String#delete_prefix * String#delete_suffix * String#downcase * String#dump * String#each_char * String#each_grapheme_cluster * String#each_line * String#gsub * String#ljust * String#lstrip * String#partition * String#reverse * String#rjust * String#rpartition * String#rstrip * String#scrub * String#slice! * String#slice / String#[] * String#split * String#squeeze * String#strip * String#sub * String#succ / String#next * String#swapcase * String#tr * String#tr_s * String#upcase * Symbol * Symbol#to_proc now returns a lambda Proc. [[Feature #16260]] * Symbol#name has been added, which returns the name of the symbol if it is named. The returned string is frozen. [[Feature #16150]] * Fiber * Introduce Fiber.set_scheduler for intercepting blocking operations and Fiber.scheduler for accessing the current scheduler. See rdoc-ref:fiber.md for more details about what operations are supported and how to implement the scheduler hooks. [[Feature #16786]] * Fiber.blocking? tells whether the current execution context is blocking. [[Feature #16786]] * Thread#join invokes the scheduler hooks `block`/`unblock` in a non-blocking execution context. [[Feature #16786]] * Thread * Thread.ignore_deadlock accessor has been added for disabling the default deadlock detection, allowing the use of signal handlers to break deadlock. [[Bug #13768]] * Warning * Warning#warn now supports a category keyword argument. [[Feature #17122]] ## Stdlib updates Outstanding ones only. * BigDecimal * Update to BigDecimal 3.0.0 * This version is Ractor compatible. * Bundler * Update to Bundler 2.2.3 * CGI * Update to 0.2.0 * This version is Ractor compatible. * CSV * Update to CSV 3.1.9 * Date * Update to Date 3.1.1 * This version is Ractor compatible. * Digest * Update to Digest 3.0.0 * This version is Ractor compatible. * Etc * Update to Etc 1.2.0 * This version is Ractor compatible. * Fiddle * Update to Fiddle 1.0.5 * IRB * Update to IRB 1.2.6 * JSON * Update to JSON 2.5.0 * This version is Ractor compatible. * Set * Update to set 1.0.0 * SortedSet has been removed for dependency and performance reasons. * Set#join is added as a shorthand for `.to_a.join`. * Set#<=> is added. * Socket * Add :connect_timeout to TCPSocket.new [[Feature #17187]] * Net::HTTP * Net::HTTP#verify_hostname= and Net::HTTP#verify_hostname have been added to skip hostname verification. [[Feature #16555]] * Net::HTTP.get, Net::HTTP.get_response, and Net::HTTP.get_print can take the request headers as a Hash in the second argument when the first argument is a URI. [[Feature #16686]] * Net::SMTP * Add SNI support. * Net::SMTP.start arguments are keyword arguments. * TLS should not check the host name by default. * OpenStruct * Initialization is no longer lazy. [[Bug #12136]] * Builtin methods can now be overridden safely. [[Bug #15409]] * Implementation uses only methods ending with `!`. * Ractor compatible. * Improved support for YAML. [[Bug #8382]] * Use officially discouraged. Read OpenStruct@Caveats section. * Pathname * Ractor compatible. * Psych * Update to Psych 3.3.0 * This version is Ractor compatible. * Reline * Update to Reline 0.1.5 * RubyGems * Update to RubyGems 3.2.3 * StringIO * Update to StringIO 3.0.0 * This version is Ractor compatible. * StringScanner * Update to StringScanner 3.0.0 * This version is Ractor compatible. ## Compatibility issues Excluding feature bug fixes. * Regexp literals and all Range objects are frozen. [[Feature #8948]] [[Feature #16377]] [[Feature #15504]] ```ruby /foo/.frozen? #=> true (42...).frozen? # => true ``` * EXPERIMENTAL: Hash#each consistently yields a 2-element array. [[Bug #12706]] * Now `{ a: 1 }.each(&->(k, v) { })` raises an ArgumentError due to lambda's arity check. * When writing to STDOUT redirected to a closed pipe, no broken pipe error message will be shown now. [[Feature #14413]] * `TRUE`/`FALSE`/`NIL` constants are no longer defined. * Integer#zero? overrides Numeric#zero? for optimization. [[Misc #16961]] * Enumerable#grep and Enumerable#grep_v when passed a Regexp and no block no longer modify Regexp.last_match. [[Bug #17030]] * Requiring 'open-uri' no longer redefines `Kernel#open`. Call `URI.open` directly or `use URI#open` instead. [[Misc #15893]] * SortedSet has been removed for dependency and performance reasons. ## Stdlib compatibility issues * Default gems * The following libraries are promoted to default gems from stdlib. * English * abbrev * base64 * drb * debug * erb * find * net-ftp * net-http * net-imap * net-protocol * open-uri * optparse * pp * prettyprint * resolv-replace * resolv * rinda * set * securerandom * shellwords * tempfile * tmpdir * time * tsort * un * weakref * The following extensions are promoted to default gems from stdlib. * digest * io-nonblock * io-wait * nkf * pathname * syslog * win32ole * Bundled gems * net-telnet and xmlrpc have been removed from the bundled gems. If you are interested in maintaining them, please comment on your plan to https://github.com/ruby/xmlrpc or https://github.com/ruby/net-telnet. * SDBM has been removed from the Ruby standard library. [[Bug #8446]] * The issues of sdbm will be handled at https://github.com/ruby/sdbm * WEBrick has been removed from the Ruby standard library. [[Feature #17303]] * The issues of WEBrick will be handled at https://github.com/ruby/webrick ## C API updates * C API functions related to $SAFE have been removed. [[Feature #16131]] * C API header file `ruby/ruby.h` was split. [[GH-2991]] This should have no impact on extension libraries, but users might experience slow compilations. * Memory view interface [EXPERIMENTAL] * The memory view interface is a C-API set to exchange a raw memory area, such as a numeric array or a bitmap image, between extension libraries. The extension libraries can share also the metadata of the memory area that consists of the shape, the element format, and so on. Using these kinds of metadata, the extension libraries can share even a multidimensional array appropriately. This feature is designed by referring to Python's buffer protocol. [[Feature #13767]] [[Feature #14722]] * Ractor related C APIs are introduced (experimental) in "include/ruby/ractor.h". ## Implementation improvements * New method cache mechanism for Ractor. [[Feature #16614]] * Inline method caches pointed from ISeq can be accessed by multiple Ractors in parallel and synchronization is needed even for method caches. However, such synchronization can be overhead so introducing new inline method cache mechanisms, (1) Disposable inline method cache (2) per-Class method cache and (3) new invalidation mechanism. (1) can avoid per-method call synchronization because it only uses atomic operations. See the ticket for more details. * The number of hashes allocated when using a keyword splat in a method call has been reduced to a maximum of 1, and passing a keyword splat to a method that accepts specific keywords does not allocate a hash. * `super` is optimized when the same type of method is called in the previous call if it's not refinements or an attr reader or writer. ### JIT * Performance improvements of JIT-ed code * Microarchitectural optimizations * Native functions shared by multiple methods are deduplicated on JIT compaction. * Decrease code size of hot paths by some optimizations and partitioning cold paths. * Instance variables * Eliminate some redundant checks. * Skip checking a class and a object multiple times in a method when possible. * Optimize accesses in some core classes like Hash and their subclasses. * Method inlining support for some C methods * `Kernel`: `#class`, `#frozen?` * `Integer`: `#-@`, `#~`, `#abs`, `#bit_length`, `#even?`, `#integer?`, `#magnitude`, `#odd?`, `#ord`, `#to_i`, `#to_int`, `#zero?` * `Struct`: reader methods for 10th or later members * Constant references are inlined. * Always generate appropriate code for `==`, `nil?`, and `!` calls depending on a receiver class. * Reduce the number of PC accesses on branches and method returns. * Optimize C method calls a little. * Compilation process improvements * It does not keep temporary files in /tmp anymore. * Throttle GC and compaction of JIT-ed code. * Avoid GC-ing JIT-ed code when not necessary. * GC-ing JIT-ed code is executed in a background thread. * Reduce the number of locks between Ruby and JIT threads. ## Static analysis ### RBS * RBS is a new language for type definition of Ruby programs. It allows writing types of classes and modules with advanced types including union types, overloading, generics, and _interface types_ for duck typing. * Ruby ships with type definitions for core/stdlib classes. * `rbs` gem is bundled to load and process RBS files. ### TypeProf * TypeProf is a type analysis tool for Ruby code based on abstract interpretation. * It reads non-annotated Ruby code, tries inferring its type signature, and prints the analysis result in RBS format. * Though it supports only a subset of the Ruby language yet, we will continuously improve the coverage of language features, analysis performance, and usability. ```ruby # test.rb def foo(x) if x > 10 x.to_s else nil end end foo(42) ``` ``` $ typeprof test.rb # Classes class Object def foo : (Integer) -> String? end ``` ## Miscellaneous changes * Methods using `ruby2_keywords` will no longer keep empty keyword splats, those are now removed just as they are for methods not using `ruby2_keywords`. * When an exception is caught in the default handler, the error message and backtrace are printed in order from the innermost. [[Feature #8661]] * Accessing an uninitialized instance variable no longer emits a warning in verbose mode.

Here, we're treating each key in # the hash as a node in the graph, and so we simply alias the required # #tsort_each_node method to Hash's #each_key method. For each key in the # hash, the associated value is an array of the node's child nodes.

The section # below is a step-by-step guide to using signed gems and generating your own. # # == Walkthrough # # === Building your certificate # # In order to start signing your gems, you'll need to build a private key and # a self-signed certificate. Here's how: # # # build a private key and certificate for yourself: # $ gem cert --build you@example.com # # This could take anywhere from a few seconds to a minute or two, depending on # the speed of your computer (public key algorithms aren't exactly the # speediest crypto algorithms in the world). When it's finished, you'll see # the files "gem-private_key.pem" and "gem-public_cert.pem" in the current # directory. # # First things first: Move both files to ~/.gem if you don't already have a # key and certificate in that directory. Ensure the file permissions make the # key unreadable by others (by default the file is saved securely). # # Keep your private key hidden; if it's compromised, someone can sign packages # as you (note: PKI has ways of mitigating the risk of stolen keys; more on # that later). # # === Signing Gems # # In RubyGems 2 and newer there is no extra work to sign a gem. RubyGems will # automatically find your key and certificate in your home directory and use # them to sign newly packaged gems. # # If your certificate is not self-signed (signed by a third party) RubyGems # will attempt to load the certificate chain from the trusted certificates. # Use <code>gem cert --add signing_cert.pem</code> to add your signers as # trusted certificates. See below for further information on certificate # chains. # # If you build your gem it will automatically be signed. If you peek inside # your gem file, you'll see a couple of new files have been added: # # $ tar tf your-gem-1.0.gem # metadata.gz # metadata.gz.sig # metadata signature # data.tar.gz # data.tar.gz.sig # data signature # checksums.yaml.gz # checksums.yaml.gz.sig # checksums signature # # === Manually signing gems # # If you wish to store your key in a separate secure location you'll need to # set your gems up for signing by hand. To do this, set the # <code>signing_key</code> and <code>cert_chain</code> in the gemspec before # packaging your gem: # # s.signing_key = '/secure/path/to/gem-private_key.pem' # s.cert_chain = %w[/secure/path/to/gem-public_cert.pem] # # When you package your gem with these options set RubyGems will automatically # load your key and certificate from the secure paths. # # === Signed gems and security policies # # Now let's verify the signature. Go ahead and install the gem, but add the # following options: <code>-P HighSecurity</code>, like this: # # # install the gem with using the security policy "HighSecurity" # $ sudo gem install your.gem -P HighSecurity # # The <code>-P</code> option sets your security policy -- we'll talk about # that in just a minute. Eh, what's this? # # $ gem install -P HighSecurity your-gem-1.0.gem # ERROR: While executing gem ... (Gem::Security::Exception) # root cert /CN=you/DC=example is not trusted # # The culprit here is the security policy. RubyGems has several different # security policies. Let's take a short break and go over the security # policies. Here's a list of the available security policies, and a brief # description of each one: # # * NoSecurity - Well, no security at all. Signed packages are treated like # unsigned packages. # * LowSecurity - Pretty much no security. If a package is signed then # RubyGems will make sure the signature matches the signing # certificate, and that the signing certificate hasn't expired, but # that's it. A malicious user could easily circumvent this kind of # security. # * MediumSecurity - Better than LowSecurity and NoSecurity, but still # fallible. Package contents are verified against the signing # certificate, and the signing certificate is checked for validity, # and checked against the rest of the certificate chain (if you don't # know what a certificate chain is, stay tuned, we'll get to that). # The biggest improvement over LowSecurity is that MediumSecurity # won't install packages that are signed by untrusted sources. # Unfortunately, MediumSecurity still isn't totally secure -- a # malicious user can still unpack the gem, strip the signatures, and # distribute the gem unsigned. # * HighSecurity - Here's the bugger that got us into this mess. # The HighSecurity policy is identical to the MediumSecurity policy, # except that it does not allow unsigned gems. A malicious user # doesn't have a whole lot of options here; they can't modify the # package contents without invalidating the signature, and they can't # modify or remove signature or the signing certificate chain, or # RubyGems will simply refuse to install the package. Oh well, maybe # they'll have better luck causing problems for CPAN users instead :). # # The reason RubyGems refused to install your shiny new signed gem was because # it was from an untrusted source. Well, your code is infallible (naturally), # so you need to add yourself as a trusted source: # # # add trusted certificate # gem cert --add ~/.gem/gem-public_cert.pem # # You've now added your public certificate as a trusted source. Now you can # install packages signed by your private key without any hassle. Let's try # the install command above again: # # # install the gem with using the HighSecurity policy (and this time # # without any shenanigans) # $ gem install -P HighSecurity your-gem-1.0.gem # Successfully installed your-gem-1.0 # 1 gem installed # # This time RubyGems will accept your signed package and begin installing. # # While you're waiting for RubyGems to work it's magic, have a look at some of # the other security commands by running <code>gem help cert</code>: # # Options: # -a, --add CERT Add a trusted certificate. # -l, --list [FILTER] List trusted certificates where the # subject contains FILTER # -r, --remove FILTER Remove trusted certificates where the # subject contains FILTER # -b, --build EMAIL_ADDR Build private key and self-signed # certificate for EMAIL_ADDR # -C, --certificate CERT Signing certificate for --sign # -K, --private-key KEY Key for --sign or --build # -A, --key-algorithm ALGORITHM Select key algorithm for --build from RSA, DSA, or EC. Defaults to RSA. # -s, --sign CERT Signs CERT with the key from -K # and the certificate from -C # -d, --days NUMBER_OF_DAYS Days before the certificate expires # -R, --re-sign Re-signs the certificate from -C with the key from -K # # We've already covered the <code>--build</code> option, and the # <code>--add</code>, <code>--list</code>, and <code>--remove</code> commands # seem fairly straightforward; they allow you to add, list, and remove the # certificates in your trusted certificate list. But what's with this # <code>--sign</code> option? # # === Certificate chains # # To answer that question, let's take a look at "certificate chains", a # concept I mentioned earlier. There are a couple of problems with # self-signed certificates: first of all, self-signed certificates don't offer # a whole lot of security. Sure, the certificate says Yukihiro Matsumoto, but # how do I know it was actually generated and signed by matz himself unless he # gave me the certificate in person? # # The second problem is scalability. Sure, if there are 50 gem authors, then # I have 50 trusted certificates, no problem. What if there are 500 gem # authors? 1000? Having to constantly add new trusted certificates is a # pain, and it actually makes the trust system less secure by encouraging # RubyGems users to blindly trust new certificates. # # Here's where certificate chains come in. A certificate chain establishes an # arbitrarily long chain of trust between an issuing certificate and a child # certificate. So instead of trusting certificates on a per-developer basis, # we use the PKI concept of certificate chains to build a logical hierarchy of # trust. Here's a hypothetical example of a trust hierarchy based (roughly) # on geography: # # -------------------------- # | rubygems@rubygems.org | # -------------------------- # | # ----------------------------------- # | | # ---------------------------- ----------------------------- # | seattlerb@seattlerb.org | | dcrubyists@richkilmer.com | # ---------------------------- ----------------------------- # | | | | # --------------- ---------------- ----------- -------------- # | drbrain | | zenspider | | pabs@dc | | tomcope@dc | # --------------- ---------------- ----------- -------------- # # # Now, rather than having 4 trusted certificates (one for drbrain, zenspider, # pabs@dc, and tomecope@dc), a user could actually get by with one # certificate, the "rubygems@rubygems.org" certificate. # # Here's how it works: # # I install "rdoc-3.12.gem", a package signed by "drbrain". I've never heard # of "drbrain", but his certificate has a valid signature from the # "seattle.rb@seattlerb.org" certificate, which in turn has a valid signature # from the "rubygems@rubygems.org" certificate. Voila! At this point, it's # much more reasonable for me to trust a package signed by "drbrain", because # I can establish a chain to "rubygems@rubygems.org", which I do trust. # # === Signing certificates # # The <code>--sign</code> option allows all this to happen. A developer # creates their build certificate with the <code>--build</code> option, then # has their certificate signed by taking it with them to their next regional # Ruby meetup (in our hypothetical example), and it's signed there by the # person holding the regional RubyGems signing certificate, which is signed at # the next RubyConf by the holder of the top-level RubyGems certificate. At # each point the issuer runs the same command: # # # sign a certificate with the specified key and certificate # # (note that this modifies client_cert.pem!) # $ gem cert -K /mnt/floppy/issuer-priv_key.pem -C issuer-pub_cert.pem # --sign client_cert.pem # # Then the holder of issued certificate (in this case, your buddy "drbrain"), # can start using this signed certificate to sign RubyGems. By the way, in # order to let everyone else know about his new fancy signed certificate, # "drbrain" would save his newly signed certificate as # <code>~/.gem/gem-public_cert.pem</code> # # Obviously this RubyGems trust infrastructure doesn't exist yet. Also, in # the "real world", issuers actually generate the child certificate from a # certificate request, rather than sign an existing certificate. And our # hypothetical infrastructure is missing a certificate revocation system. # These are that can be fixed in the future... # # At this point you should know how to do all of these new and interesting # things: # # * build a gem signing key and certificate # * adjust your security policy # * modify your trusted certificate list # * sign a certificate # # == Manually verifying signatures # # In case you don't trust RubyGems you can verify gem signatures manually: # # 1. Fetch and unpack the gem # # gem fetch some_signed_gem # tar -xf some_signed_gem-1.0.gem # # 2. Grab the public key from the gemspec # # gem spec some_signed_gem-1.0.gem cert_chain | \ # ruby -ryaml -e 'puts YAML.load($stdin)' > public_key.crt # # 3. Generate a SHA1 hash of the data.tar.gz # # openssl dgst -sha1 < data.tar.gz > my.hash # # 4. Verify the signature # # openssl rsautl -verify -inkey public_key.crt -certin \ # -in data.tar.gz.sig > verified.hash # # 5. Compare your hash to the verified hash # # diff -s verified.hash my.hash # # 6. Repeat 5 and 6 with metadata.gz # # == OpenSSL Reference # # The .pem files generated by --build and --sign are PEM files. Here's a # couple of useful OpenSSL commands for manipulating them: # # # convert a PEM format X509 certificate into DER format: # # (note: Windows .cer files are X509 certificates in DER format) # $ openssl x509 -in input.pem -outform der -out output.der # # # print out the certificate in a human-readable format: # $ openssl x509 -in input.pem -noout -text # # And you can do the same thing with the private key file as well: # # # convert a PEM format RSA key into DER format: # $ openssl rsa -in input_key.pem -outform der -out output_key.der # # # print out the key in a human readable format: # $ openssl rsa -in input_key.pem -noout -text # # == Bugs/TODO # # * There's no way to define a system-wide trust list. # * custom security policies (from a YAML file, etc) # * Simple method to generate a signed certificate request # * Support for OCSP, SCVP, CRLs, or some other form of cert status check # (list is in order of preference) # * Support for encrypted private keys # * Some sort of semi-formal trust hierarchy (see long-winded explanation # above) # * Path discovery (for gem certificate chains that don't have a self-signed # root) -- by the way, since we don't have this, THE ROOT OF THE CERTIFICATE # CHAIN MUST BE SELF SIGNED if Policy#verify_root is true (and it is for the # MediumSecurity and HighSecurity policies) # * Better explanation of X509 naming (ie, we don't have to use email # addresses) # * Honor AIA field (see note about OCSP above) # * Honor extension restrictions # * Might be better to store the certificate chain as a PKCS#7 or PKCS#12 # file, instead of an array embedded in the metadata. # # == Original author # # Paul Duncan <pabs@pablotron.org> # http://pablotron.org/ module Gem::Security ## # Gem::Security default exception type class Exception < Gem::Exception; end ## # Used internally to select the signing digest from all computed digests DIGEST_NAME = 'SHA256' # :nodoc: ## # Length of keys created by RSA and DSA keys RSA_DSA_KEY_LENGTH = 3072 ## # Default algorithm to use when building a key pair DEFAULT_KEY_ALGORITHM = 'RSA' ## # Named curve used for Elliptic Curve EC_NAME = 'secp384r1' ## # Cipher used to encrypt the key pair used to sign gems. # Must be in the list returned by OpenSSL::Cipher.ciphers KEY_CIPHER = OpenSSL::Cipher.new('AES-256-CBC') if defined?(OpenSSL::Cipher) ## # One day in seconds ONE_DAY = 86400 ## # One year in seconds ONE_YEAR = ONE_DAY * 365 ## # The default set of extensions are: # # * The certificate is not a certificate authority # * The key for the certificate may be used for key and data encipherment # and digital signatures # * The certificate contains a subject key identifier EXTENSIONS = { 'basicConstraints' => 'CA:FALSE', 'keyUsage' => 'keyEncipherment,dataEncipherment,digitalSignature', 'subjectKeyIdentifier' => 'hash', }.freeze def self.alt_name_or_x509_entry(certificate, x509_entry) alt_name = certificate.extensions.find do |extension| extension.oid == "#{x509_entry}AltName" end return alt_name.value if alt_name certificate.send x509_entry end ## # Creates an unsigned certificate for +subject+ and +key+.

The RubyGems implementation is designed to be compatible with Bundler's Gemfile format. You can see additional documentation on the format at: http://bundler.io RubyGems automatically looks for these gem dependencies files: * gem.deps.rb * Gemfile * Isolate These files are looked up automatically using `gem install -g`, or you can specify a custom file. When the RUBYGEMS_GEMDEPS environment variable is set to a gem dependencies file the gems from that file will be activated at startup time. Set it to a specific filename or to "-" to have RubyGems automatically discover the gem dependencies file by walking up from the current directory. You can also activate gem dependencies at program startup using Gem.use_gemdeps. NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control. Gem Dependencies ================ Use #gem to declare which gems you directly depend upon: gem 'rake' To depend on a specific set of versions: gem 'rake', '~> 10.3', '>= 10.3.2' RubyGems will require the gem name when activating the gem using the RUBYGEMS_GEMDEPS environment variable or Gem::use_gemdeps. Use the require: option to override this behavior if the gem does not have a file of that name or you don't want to require those files: gem 'my_gem', require: 'other_file' To prevent RubyGems from requiring any files use: gem 'my_gem', require: false To load dependencies from a .gemspec file: gemspec RubyGems looks for the first .gemspec file in the current directory. To override this use the name: option: gemspec name: 'specific_gem' To look in a different directory use the path: option: gemspec name: 'specific_gem', path: 'gemspecs' To depend on a gem unpacked into a local directory: gem 'modified_gem', path: 'vendor/modified_gem' To depend on a gem from git: gem 'private_gem', git: 'git@my.company.example:private_gem.git' To depend on a gem from github: gem 'private_gem', github: 'my_company/private_gem' To depend on a gem from a github gist: gem 'bang', gist: '1232884' Git, github and gist support the ref:, branch: and tag: options to specify a commit reference or hash, branch or tag respectively to use for the gem. Setting the submodules: option to true for git, github and gist dependencies causes fetching of submodules when fetching the repository. You can depend on multiple gems from a single repository with the git method: git 'https://github.com/rails/rails.git' do gem 'activesupport' gem 'activerecord' end Gem Sources =========== RubyGems uses the default sources for regular `gem install` for gem dependencies files. Unlike bundler, you do need to specify a source. You can override the sources used for downloading gems with: source 'https://gem_server.example' You may specify multiple sources. Unlike bundler the prepend: option is not supported. Sources are used in-order, to prepend a source place it at the front of the list. Gem Platform ============ You can restrict gem dependencies to specific platforms with the #platform and #platforms methods: platform :ruby_21 do gem 'debugger' end See the bundler Gemfile manual page for a list of platforms supported in a gem dependencies file.: http://bundler.io/v1.6/man/gemfile.5.html Ruby Version and Engine Dependency ================================== You can specify the version, engine and engine version of ruby to use with your gem dependencies file. If you are not running the specified version RubyGems will raise an exception. To depend on a specific version of ruby: ruby '2.1.2' To depend on a specific ruby engine: ruby '1.9.3', engine: 'jruby' To depend on a specific ruby engine version: ruby '1.9.3', engine: 'jruby', engine_version: '1.7.11' Grouping Dependencies ===================== Gem dependencies may be placed in groups that can be excluded from install. Dependencies required for development or testing of your code may be excluded when installed in a production environment. A #gem dependency may be placed in a group using the group: option: gem 'minitest', group: :test To install dependencies from a gemfile without specific groups use the `--without` option for `gem install -g`: $ gem install -g --without test The group: option also accepts multiple groups if the gem fits in multiple categories. Multiple groups may be excluded during install by comma-separating the groups for `--without` or by specifying `--without` multiple times. The #group method can also be used to place gems in groups: group :test do gem 'minitest' gem 'minitest-emoji' end The #group method allows multiple groups. The #gemspec development dependencies are placed in the :development group by default. This may be overridden with the :development_group option: gemspec development_group: :other EOF PLATFORMS = <<-'EOF'.freeze RubyGems platforms are composed of three parts, a CPU, an OS, and a version. These values are taken from values in rbconfig.rb. You can view your current platform by running `gem environment`. RubyGems matches platforms as follows: * The CPU must match exactly unless one of the platforms has "universal" as the CPU or the local CPU starts with "arm" and the gem's CPU is exactly "arm" (for gems that support generic ARM architecture). * The OS must match exactly. * The versions must match exactly unless one of the versions is nil. For commands that install, uninstall and list gems, you can override what RubyGems thinks your platform is with the --platform option. The platform you pass must match "#{cpu}-#{os}" or "#{cpu}-#{os}-#{version}". On mswin platforms, the version is the compiler version, not the OS version. (Ruby compiled with VC6 uses "60" as the compiler version, VC8 uses "80".) For the ARM architecture, gems with a platform of "arm-linux" should run on a reasonable set of ARM CPUs and not depend on instructions present on a limited subset of the architecture. For example, the binary should run on platforms armv5, armv6hf, armv6l, armv7, etc. If you use the "arm-linux" platform please test your gem on a variety of ARM hardware before release to ensure it functions correctly. Example platforms: x86-freebsd # Any FreeBSD version on an x86 CPU universal-darwin-8 # Darwin 8 only gems that run on any CPU x86-mswin32-80 # Windows gems compiled with VC8 armv7-linux # Gem complied for an ARMv7 CPU running linux arm-linux # Gem compiled for any ARM CPU running linux When building platform gems, set the platform in the gem specification to Gem::Platform::CURRENT. This will correctly mark the gem with your ruby's platform.

The wrapper allows you to choose among alternate gem versions using _version_. For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer version is also installed. Gem Dependency Files ==================== RubyGems can install a consistent set of gems across multiple environments using `gem install -g` when a gem dependencies file (gem.deps.rb, Gemfile or Isolate) is present. If no explicit file is given RubyGems attempts to find one in the current directory. When the RUBYGEMS_GEMDEPS environment variable is set to a gem dependencies file the gems from that file will be activated at startup time. Set it to a specific filename or to "-" to have RubyGems automatically discover the gem dependencies file by walking up from the current directory. NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control. Extension Install Failures ========================== If an extension fails to compile during gem installation the gem specification is not written out, but the gem remains unpacked in the repository. You may need to specify the path to the library's headers and libraries to continue.

A version string should normally be a series of numbers # separated by periods. Each part (digits separated by periods) is # considered its own number, and these are used for sorting. So for # instance, 3.10 sorts higher than 3.2 because ten is greater than # two. # # If any part contains letters (currently only a-z are supported) then # that version is considered prerelease. Versions with a prerelease # part in the Nth part sort less than versions with N-1 # parts. Prerelease parts are sorted alphabetically using the normal # Ruby string sorting rules. If a prerelease part contains both # letters and numbers, it will be broken into multiple parts to # provide expected sort behavior (1.0.a10 becomes 1.0.a.10, and is # greater than 1.0.a9). # # Prereleases sort between real releases (newest to oldest): # # 1. 1.0 # 2. 1.0.b1 # 3. 1.0.a.2 # 4. 0.9 # # If you want to specify a version restriction that includes both prereleases # and regular releases of the 1.x series this is the best way: # # s.add_dependency 'example', '>= 1.0.0.a', '< 2.0.0' # # == How Software Changes # # Users expect to be able to specify a version constraint that gives them # some reasonable expectation that new versions of a library will work with # their software if the version constraint is true, and not work with their # software if the version constraint is false. In other words, the perfect # system will accept all compatible versions of the library and reject all # incompatible versions. # # Libraries change in 3 ways (well, more than 3, but stay focused here!). # # 1. The change may be an implementation detail only and have no effect on # the client software. # 2. The change may add new features, but do so in a way that client software # written to an earlier version is still compatible. # 3. The change may change the public interface of the library in such a way # that old software is no longer compatible. # # Some examples are appropriate at this point. Suppose I have a Stack class # that supports a <tt>push</tt> and a <tt>pop</tt> method. # # === Examples of Category 1 changes: # # * Switch from an array based implementation to a linked-list based # implementation. # * Provide an automatic (and transparent) backing store for large stacks. # # === Examples of Category 2 changes might be: # # * Add a <tt>depth</tt> method to return the current depth of the stack. # * Add a <tt>top</tt> method that returns the current top of stack (without # changing the stack). # * Change <tt>push</tt> so that it returns the item pushed (previously it # had no usable return value). # # === Examples of Category 3 changes might be: # # * Changes <tt>pop</tt> so that it no longer returns a value (you must use # <tt>top</tt> to get the top of the stack). # * Rename the methods to <tt>push_item</tt> and <tt>pop_item</tt>. # # == RubyGems Rational Versioning # # * Versions shall be represented by three non-negative integers, separated # by periods (e.g. 3.1.4). The first integers is the "major" version # number, the second integer is the "minor" version number, and the third # integer is the "build" number. # # * A category 1 change (implementation detail) will increment the build # number. # # * A category 2 change (backwards compatible) will increment the minor # version number and reset the build number. # # * A category 3 change (incompatible) will increment the major build number # and reset the minor and build numbers. # # * Any "public" release of a gem should have a different version. Normally # that means incrementing the build number. This means a developer can # generate builds all day long, but as soon as they make a public release, # the version must be updated. # # === Examples # # Let's work through a project lifecycle using our Stack example from above. # # Version 0.0.1:: The initial Stack class is release. # Version 0.0.2:: Switched to a linked=list implementation because it is # cooler. # Version 0.1.0:: Added a <tt>depth</tt> method. # Version 1.0.0:: Added <tt>top</tt> and made <tt>pop</tt> return nil # (<tt>pop</tt> used to return the old top item). # Version 1.1.0:: <tt>push</tt> now returns the value pushed (it used it # return nil). # Version 1.1.1:: Fixed a bug in the linked list implementation. # Version 1.1.2:: Fixed a bug introduced in the last fix. # # Client A needs a stack with basic push/pop capability. They write to the # original interface (no <tt>top</tt>), so their version constraint looks like: # # gem 'stack', '>= 0.0' # # Essentially, any version is OK with Client A. An incompatible change to # the library will cause them grief, but they are willing to take the chance # (we call Client A optimistic). # # Client B is just like Client A except for two things: (1) They use the # <tt>depth</tt> method and (2) they are worried about future # incompatibilities, so they write their version constraint like this: # # gem 'stack', '~> 0.1' # # The <tt>depth</tt> method was introduced in version 0.1.0, so that version # or anything later is fine, as long as the version stays below version 1.0 # where incompatibilities are introduced. We call Client B pessimistic # because they are worried about incompatible future changes (it is OK to be # pessimistic!). # # == Preventing Version Catastrophe: # # From: http://blog.zenspider.com/2008/10/rubygems-howto-preventing-cata.html # # Let's say you're depending on the fnord gem version 2.y.z.

#++ # # == Gem::OptionParser # # === New to \Gem::OptionParser? # # See the {Tutorial}[./doc/optparse/tutorial_rdoc.html]. # # === Introduction # # Gem::OptionParser is a class for command-line option analysis. It is much more # advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented # solution. # # === Features # # 1. The argument specification and the code to handle it are written in the # same place. # 2. It can output an option summary; you don't need to maintain this string # separately. # 3. Optional and mandatory arguments are specified very gracefully. # 4. Arguments can be automatically converted to a specified class. # 5. Arguments can be restricted to a certain set. # # All of these features are demonstrated in the examples below. See # #make_switch for full documentation. # # === Minimal example # # require 'rubygems/optparse/lib/optparse' # # options = {} # Gem::OptionParser.new do |parser| # parser.banner = "Usage: example.rb [options]" # # parser.on("-v", "--[no-]verbose", "Run verbosely") do |v| # options[:verbose] = v # end # end.parse! # # p options # p ARGV # # === Generating Help # # Gem::OptionParser can be used to automatically generate help for the commands you # write: # # require 'rubygems/optparse/lib/optparse' # # Options = Struct.new(:name) # # class Parser # def self.parse(options) # args = Options.new("world") # # opt_parser = Gem::OptionParser.new do |parser| # parser.banner = "Usage: example.rb [options]" # # parser.on("-nNAME", "--name=NAME", "Name to say hello to") do |n| # args.name = n # end # # parser.on("-h", "--help", "Prints this help") do # puts parser # exit # end # end # # opt_parser.parse!(options) # return args # end # end # options = Parser.parse %w[--help] # # #=> # # Usage: example.rb [options] # # -n, --name=NAME Name to say hello to # # -h, --help Prints this help # # === Required Arguments # # For options that require an argument, option specification strings may include an # option name in all caps. If an option is used without the required argument, # an exception will be raised. # # require 'rubygems/optparse/lib/optparse' # # options = {} # Gem::OptionParser.new do |parser| # parser.on("-r", "--require LIBRARY", # "Require the LIBRARY before executing your script") do |lib| # puts "You required #{lib}!" # end # end.parse! # # Used: # # $ ruby optparse-test.rb -r # optparse-test.rb:9:in `<main>': missing argument: -r (Gem::OptionParser::MissingArgument) # $ ruby optparse-test.rb -r my-library # You required my-library! # # === Type Coercion # # Gem::OptionParser supports the ability to coerce command line arguments # into objects for us. # # Gem::OptionParser comes with a few ready-to-use kinds of type # coercion. They are: # # - Date -- Anything accepted by +Date.parse+ # - DateTime -- Anything accepted by +DateTime.parse+ # - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+ # - URI -- Anything accepted by +URI.parse+ # - Shellwords -- Anything accepted by +Shellwords.shellwords+ # - String -- Any non-empty string # - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040) # - Float -- Any float. (e.g. 10, 3.14, -100E+13) # - Numeric -- Any integer, float, or rational (1, 3.4, 1/3) # - DecimalInteger -- Like +Integer+, but no octal format. # - OctalInteger -- Like +Integer+, but no decimal format. # - DecimalNumeric -- Decimal integer or float. # - TrueClass -- Accepts '+, yes, true, -, no, false' and # defaults as +true+ # - FalseClass -- Same as +TrueClass+, but defaults to +false+ # - Array -- Strings separated by ',' (e.g. 1,2,3) # - Regexp -- Regular expressions.

If the gem does not exist in this source, it will not be installed\. . .P Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on global sources using the ordering described in \fISOURCE PRIORITY\fR\. . .P Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in \fIGLOBAL SOURCES (#source)\fR\. . .P Using the \fB:source\fR option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources\. . .SS "GIT" If necessary, you can specify that a gem is located at a particular git repository using the \fB:git\fR parameter\. The repository can be accessed via several protocols: . .TP \fBHTTP(S)\fR gem "rails", :git => "https://github\.com/rails/rails\.git" . .TP \fBSSH\fR gem "rails", :git => "git@github\.com:rails/rails\.git" . .TP \fBgit\fR gem "rails", :git => "git://github\.com/rails/rails\.git" . .P If using SSH, the user that you use to run \fBbundle install\fR \fBMUST\fR have the appropriate keys available in their \fB$HOME/\.ssh\fR\. . .P \fBNOTE\fR: \fBhttp://\fR and \fBgit://\fR URLs should be avoided if at all possible\. These protocols are unauthenticated, so a man\-in\-the\-middle attacker can deliver malicious code and compromise your system\. HTTPS and SSH are strongly preferred\. . .P The \fBgroup\fR, \fBplatforms\fR, and \fBrequire\fR options are available and behave exactly the same as they would for a normal gem\. . .P A git repository \fBSHOULD\fR have at least one file, at the root of the directory containing the gem, with the extension \fB\.gemspec\fR\. This file \fBMUST\fR contain a valid gem specification, as expected by the \fBgem build\fR command\. . .P If a git repository does not have a \fB\.gemspec\fR, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions\. As a result, it may fail to properly integrate into your application\. . .P If a git repository does have a \fB\.gemspec\fR for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the \fB\.gemspec\fR specifies a version matching the version specifier\. If not, bundler will print a warning\. . .IP "" 4 . .nf gem "rails", "2\.3\.8", :git => "https://github\.com/rails/rails\.git" # bundle install will fail, because the \.gemspec in the rails # repository\'s master branch specifies version 3\.0\.0 . .fi . .IP "" 0 . .P If a git repository does \fBnot\fR have a \fB\.gemspec\fR for the gem you attached it to, a version specifier \fBMUST\fR be provided\. Bundler will use this version in the simple \fB\.gemspec\fR it creates\. . .P Git repositories support a number of additional options\. . .TP \fBbranch\fR, \fBtag\fR, and \fBref\fR You \fBMUST\fR only specify at most one of these options\. The default is \fB:branch => "master"\fR\. For example: . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :branch => "5\-0\-stable" . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :tag => "v5\.0\.0" . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :ref => "4aded" . .TP \fBsubmodules\fR For reference, a git submodule \fIhttps://git\-scm\.com/book/en/v2/Git\-Tools\-Submodules\fR lets you have another git repository within a subfolder of your repository\. Specify \fB:submodules => true\fR to cause bundler to expand any submodules included in the git repository . .P If a git repository contains multiple \fB\.gemspecs\fR, each \fB\.gemspec\fR represents a gem located at the same place in the file system as the \fB\.gemspec\fR\. . .IP "" 4 . .nf |~rails [git root] | |\-rails\.gemspec [rails gem located here] |~actionpack | |\-actionpack\.gemspec [actionpack gem located here] |~activesupport | |\-activesupport\.gemspec [activesupport gem located here] |\.\.\. . .fi . .IP "" 0 . .P To install a gem located in a git repository, bundler changes to the directory containing the gemspec, runs \fBgem build name\.gemspec\fR and then installs the resulting gem\. The \fBgem build\fR command, which comes standard with Rubygems, evaluates the \fB\.gemspec\fR in the context of the directory in which it is located\. . .SS "GIT SOURCE" A custom git source can be defined via the \fBgit_source\fR method\.

This allows a man\-in\-the\-middle attacker to compromise your system\. . .P If the git repository you want to use is hosted on GitHub and is public, you can use the :github shorthand to specify the github username and repository name (without the trailing "\.git"), separated by a slash\.

Relative paths are resolved relative to the directory containing the \fBGemfile\fR\. . .P Similar to the semantics of the \fB:git\fR option, the \fB:path\fR option requires that the directory in question either contains a \fB\.gemspec\fR for the gem, or that you specify an explicit version that bundler should use\. . .P Unlike \fB:git\fR, bundler does not compile C extensions for gems specified as paths\. . .IP "" 4 . .nf gem "rails", :path => "vendor/rails" . .fi . .IP "" 0 . .P If you would like to use multiple local gems directly from the filesystem, you can set a global \fBpath\fR option to the path containing the gem\'s files\.

Thus, when defining source blocks, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources, either via source blocks or \fB:source\fR directives on individual gems\. . .SH "INSTALL_IF" The \fBinstall_if\fR method allows gems to be installed based on a proc or lambda\.

Some required Gemspec attributes include the name, description, and homepage of your gem\. This is also where you specify the dependencies your gem needs to run\. . .P If you wish to use Bundler to help install dependencies for a gem while it is being developed, use the \fBgemspec\fR method to pull in the dependencies listed in the \fB\.gemspec\fR file\. . .P The \fBgemspec\fR method adds any runtime dependencies as gem requirements in the default group\. It also adds development dependencies as gem requirements in the \fBdevelopment\fR group\. Finally, it adds a gem requirement on your project (\fB:path => \'\.\'\fR)\. In conjunction with \fBBundler\.setup\fR, this allows you to require project files in your test code as you would if the project were installed as a gem; you need not manipulate the load path manually or require project files via relative paths\. . .P The \fBgemspec\fR method supports optional \fB:path\fR, \fB:glob\fR, \fB:name\fR, and \fB:development_group\fR options, which control where bundler looks for the \fB\.gemspec\fR, the glob it uses to look for the gemspec (defaults to: "{,\fI,\fR/*}\.gemspec"), what named \fB\.gemspec\fR it uses (if more than one is present), and which group development dependencies are included in\. . .P When a \fBgemspec\fR dependency encounters version conflicts during resolution, the local version under development will always be selected \-\- even if there are remote versions that better match other requirements for the \fBgemspec\fR gem\. . .SH "SOURCE PRIORITY" When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order: . .IP "1." 4 The source explicitly attached to the gem (using \fB:source\fR, \fB:path\fR, or \fB:git\fR) . .IP "2." 4 For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent\.

Bundler remembers the exact versions it installed in \fBGemfile\.lock\fR\. The next time you run bundle install(1) \fIbundle\-install\.1\.html\fR, bundler skips the dependency resolution and installs the same gems as it installed last time\. . .P After checking in the \fBGemfile\.lock\fR into version control and cloning it on another machine, running bundle install(1) \fIbundle\-install\.1\.html\fR will \fIstill\fR install the gems that you installed last time\. You don\'t need to worry that a new release of \fBerubis\fR or \fBmail\fR changes the gems you use\. . .P However, from time to time, you might want to update the gems you are using to the newest versions that still match the gems in your Gemfile(5)\. . .P To do this, run \fBbundle update \-\-all\fR, which will ignore the \fBGemfile\.lock\fR, and resolve all the dependencies again\. Keep in mind that this process can result in a significantly different set of the 25 gems, based on the requirements of new gems that the gem authors released since the last time you ran \fBbundle update \-\-all\fR\. . .SH "UPDATING A LIST OF GEMS" Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\. . .P For instance, in the scenario above, imagine that \fBnokogiri\fR releases version \fB1\.4\.4\fR, and you want to update it \fIwithout\fR updating Rails and all of its dependencies\. To do this, run \fBbundle update nokogiri\fR\. . .P Bundler will update \fBnokogiri\fR and any of its dependencies, but leave alone Rails and its dependencies\. . .SH "OVERLAPPING DEPENDENCIES" Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same second\-level dependency\. For instance, consider the case of \fBthin\fR and \fBrack\-perftools\-profiler\fR\. . .IP "" 4 . .nf source "https://rubygems\.org" gem "thin" gem "rack\-perftools\-profiler" . .fi . .IP "" 0 . .P The \fBthin\fR gem depends on \fBrack >= 1\.0\fR, while \fBrack\-perftools\-profiler\fR depends on \fBrack ~> 1\.0\fR\.

If you run \fBbundle update thin\fR, bundler will update \fBdaemons\fR, \fBeventmachine\fR and \fBrack\fR, which are dependencies of \fBthin\fR, but not \fBopen4\fR or \fBperftools\.rb\fR, which are dependencies of \fBrack\-perftools_profiler\fR\. Note that \fBbundle update thin\fR will update \fBrack\fR even though it\'s \fIalso\fR a dependency of \fBrack\-perftools_profiler\fR\. . .P In short, by default, when you update a gem using \fBbundle update\fR, bundler will update all dependencies of that gem, including those that are also dependencies of another gem\. . .P To prevent updating indirect dependencies, prior to version 1\.14 the only option was the \fBCONSERVATIVE UPDATING\fR behavior in bundle install(1) \fIbundle\-install\.1\.html\fR: . .P In this scenario, updating the \fBthin\fR version manually in the Gemfile(5), and then running bundle install(1) \fIbundle\-install\.1\.html\fR will only update \fBdaemons\fR and \fBeventmachine\fR, but not \fBrack\fR\. For more information, see the \fBCONSERVATIVE UPDATING\fR section of bundle install(1) \fIbundle\-install\.1\.html\fR\. . .P Starting with 1\.14, specifying the \fB\-\-conservative\fR option will also prevent indirect dependencies from being updated\. . .SH "PATCH LEVEL OPTIONS" Version 1\.14 introduced 4 patch\-level options that will influence how gem versions are resolved\. One of the following options can be used: \fB\-\-patch\fR, \fB\-\-minor\fR or \fB\-\-major\fR\. \fB\-\-strict\fR can be added to further influence resolution\. . .TP \fB\-\-patch\fR Prefer updating only to next patch version\. . .TP \fB\-\-minor\fR Prefer updating only to next minor version\. . .TP \fB\-\-major\fR Prefer updating to next major version (default)\. . .TP \fB\-\-strict\fR Do not allow any gem to be updated past latest \fB\-\-patch\fR | \fB\-\-minor\fR | \fB\-\-major\fR\. . .P When Bundler is resolving what versions to use to satisfy declared requirements in the Gemfile or in parent gems, it looks up all available versions, filters out any versions that don\'t satisfy the requirement, and then, by default, sorts them from newest to oldest, considering them in that order\. . .P Providing one of the patch level options (e\.g\. \fB\-\-patch\fR) changes the sort order of the satisfying versions, causing Bundler to consider the latest \fB\-\-patch\fR or \fB\-\-minor\fR version available before other versions\. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph\. . .P For example, if gem \'foo\' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\. . .P If the \fB\-\-patch\fR option is used, the order of preference will change to "1\.0\.4, 1\.0\.3, 1\.0\.2, 1\.1\.1, 1\.1\.0, 2\.0\.0"\. . .P If the \fB\-\-minor\fR option is used, the order of preference will change to "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2, 2\.0\.0"\. . .P Combining the \fB\-\-strict\fR option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far\. . .P To continue the previous example, if both \fB\-\-patch\fR and \fB\-\-strict\fR options are used, the available versions for resolution would be "1\.0\.4, 1\.0\.3, 1\.0\.2"\. If \fB\-\-minor\fR and \fB\-\-strict\fR are used, it would be "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\. . .P Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available\. If the gem requirement for \fBfoo\fR in the Gemfile is \'~> 1\.0\', that will accomplish the same thing as providing the \fB\-\-minor\fR and \fB\-\-strict\fR options\. . .SH "PATCH LEVEL EXAMPLES" Given the following gem specifications: . .IP "" 4 . .nf foo 1\.4\.3, requires: ~> bar 2\.0 foo 1\.4\.4, requires: ~> bar 2\.0 foo 1\.4\.5, requires: ~> bar 2\.1 foo 1\.5\.0, requires: ~> bar 2\.1 foo 1\.5\.1, requires: ~> bar 3\.0 bar with versions 2\.0\.3, 2\.0\.4, 2\.1\.0, 2\.1\.1, 3\.0\.0 . .fi . .IP "" 0 . .P Gemfile: . .IP "" 4 . .nf gem \'foo\' . .fi . .IP "" 0 . .P Gemfile\.lock: . .IP "" 4 . .nf foo (1\.4\.3) bar (~> 2\.0) bar (2\.0\.3) . .fi . .IP "" 0 . .P Cases: . .IP "" 4 . .nf # Command Line Result \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1 bundle update \-\-patch \'foo 1\.4\.5\', \'bar 2\.1\.1\' 2 bundle update \-\-patch foo \'foo 1\.4\.5\', \'bar 2\.1\.1\' 3 bundle update \-\-minor \'foo 1\.5\.1\', \'bar 3\.0\.0\' 4 bundle update \-\-minor \-\-strict \'foo 1\.5\.0\', \'bar 2\.1\.1\' 5 bundle update \-\-patch \-\-strict \'foo 1\.4\.4\', \'bar 2\.0\.4\' . .fi . .IP "" 0 . .P In case 1, bar is upgraded to 2\.1\.1, a minor version increase, because the dependency from foo 1\.4\.5 required it\. . .P In case 2, only foo is requested to be unlocked, but bar is also allowed to move because it\'s not a declared dependency in the Gemfile\. . .P In case 3, bar goes up a whole major release, because a minor increase is preferred now for foo, and when it goes to 1\.5\.1, it requires 3\.0\.0 of bar\. . .P In case 4, foo is preferred up to a minor version, but 1\.5\.1 won\'t work because the \-\-strict flag removes bar 3\.0\.0 from consideration since it\'s a major increment\. . .P In case 5, both foo and bar have any minor or major increments removed from consideration because of the \-\-strict flag, so the most they can move is up to 1\.4\.4 and 2\.0\.4\. . .SH "RECOMMENDED WORKFLOW" In general, when working with an application managed with bundler, you should use the following workflow: . .IP "\(bu" 4 After you create your Gemfile(5) for the first time, run . .IP $ bundle install . .IP "\(bu" 4 Check the resulting \fBGemfile\.lock\fR into version control . .IP $ git add Gemfile\.lock . .IP "\(bu" 4 When checking out this repository on another development machine, run . .IP $ bundle install . .IP "\(bu" 4 When checking out this repository on a deployment machine, run . .IP $ bundle install \-\-deployment . .IP "\(bu" 4 After changing the Gemfile(5) to reflect a new or update dependency, run . .IP $ bundle install . .IP "\(bu" 4 Make sure to check the updated \fBGemfile\.lock\fR into version control . .IP $ git add Gemfile\.lock . .IP "\(bu" 4 If bundle install(1) \fIbundle\-install\.1\.html\fR reports a conflict, manually update the specific gems that you changed in the Gemfile(5) . .IP $ bundle update rails thin . .IP "\(bu" 4 If you want to update all the gems to the latest possible versions that still match the gems listed in the Gemfile(5), run . .IP $ bundle update \-\-all . .IP "" 0 man/man1/bundle-open.1 0000644 00000001105 15102661023 0010436 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-OPEN" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-open\fR \- Opens the source directory for a gem in your bundle . .SH "SYNOPSIS" \fBbundle open\fR [GEM] . .SH "DESCRIPTION" Opens the source directory of the provided GEM in your editor\. . .P For this to work the \fBEDITOR\fR or \fBBUNDLER_EDITOR\fR environment variable has to be set\. . .P Example: . .IP "" 4 . .nf bundle open \'rack\' . .fi . .IP "" 0 . .P Will open the source directory for the \'rack\' gem in your bundle\. man/man1/bundle-show.1 0000644 00000001262 15102661023 0010461 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-SHOW" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-show\fR \- Shows all the gems in your bundle, or the path to a gem . .SH "SYNOPSIS" \fBbundle show\fR [GEM] [\-\-paths] . .SH "DESCRIPTION" Without the [GEM] option, \fBshow\fR will print a list of the names and versions of all gems that are required by your [\fBGemfile(5)\fR][Gemfile(5)], sorted by name\. . .P Calling show with [GEM] will list the exact location of that gem on your machine\. . .SH "OPTIONS" . .TP \fB\-\-paths\fR List the paths of all gems that are required by your [\fBGemfile(5)\fR][Gemfile(5)], sorted by gem name\. man/man1/rake.1 0000644 00000007215 15102661023 0007160 0 ustar 00 .Dd June 12, 2016 .Dt RAKE 1 .Os rake 11.2.2 .Sh NAME .Nm rake .Nd make-like build utility for Ruby .Sh SYNOPSIS .Nm .Op Fl f Ar rakefile .Op Ar options .Ar targets ... .Sh DESCRIPTION .Nm is a .Xr make 1 Ns -like build utility for Ruby.

It has many features to process text files and to do system management tasks (like in Perl). It is simple, straight-forward, and extensible. .Pp If you want a language for easy object-oriented programming, or you don't like the Perl ugliness, or you do like the concept of LISP, but don't like too many parentheses, Ruby might be your language of choice. .Sh FEATURES Ruby's features are as follows: .Bl -tag -width 6n .It Sy "Interpretive" Ruby is an interpreted language, so you don't have to recompile programs written in Ruby to execute them. .Pp .It Sy "Variables have no type (dynamic typing)" Variables in Ruby can contain data of any type. You don't have to worry about variable typing. Consequently, it has a weaker compile time check. .Pp .It Sy "No declaration needed" You can use variables in your Ruby programs without any declarations. Variable names denote their scope - global, class, instance, or local. .Pp .It Sy "Simple syntax" Ruby has a simple syntax influenced slightly from Eiffel. .Pp .It Sy "No user-level memory management" Ruby has automatic memory management. Objects no longer referenced from anywhere are automatically collected by the garbage collector built into the interpreter. .Pp .It Sy "Everything is an object" Ruby is a purely object-oriented language, and was so since its creation. Even such basic data as integers are seen as objects. .Pp .It Sy "Class, inheritance, and methods" Being an object-oriented language, Ruby naturally has basic features like classes, inheritance, and methods. .Pp .It Sy "Singleton methods" Ruby has the ability to define methods for certain objects. For example, you can define a press-button action for certain widget by defining a singleton method for the button. Or, you can make up your own prototype based object system using singleton methods, if you want to. .Pp .It Sy "Mix-in by modules" Ruby intentionally does not have the multiple inheritance as it is a source of confusion. Instead, Ruby has the ability to share implementations across the inheritance tree. This is often called a .Sq Mix-in . .Pp .It Sy "Iterators" Ruby has iterators for loop abstraction. .Pp .It Sy "Closures" In Ruby, you can objectify the procedure. .Pp .It Sy "Text processing and regular expressions" Ruby has a bunch of text processing features like in Perl. .Pp .It Sy "M17N, character set independent" Ruby supports multilingualized programming. Easy to process texts written in many different natural languages and encoded in many different character encodings, without dependence on Unicode. .Pp .It Sy "Bignums" With built-in bignums, you can for example calculate factorial(400). .Pp .It Sy "Reflection and domain specific languages" Class is also an instance of the Class class. Definition of classes and methods is an expression just as 1+1 is. So your programs can even write and modify programs. Thus you can write your application in your own programming language on top of Ruby. .Pp .It Sy "Exception handling" As in Java(tm). .Pp .It Sy "Direct access to the OS" Ruby can use most .Ux system calls, often used in system programming. .Pp .It Sy "Dynamic loading" On most .Ux systems, you can load object files into the Ruby interpreter on-the-fly. .It Sy "Rich libraries" In addition to the .Dq builtin libraries and .Dq standard libraries that are bundled with Ruby, a vast amount of third-party libraries .Pq Dq gems are available via the package management system called .Sq RubyGems , namely the .Xr gem 1 command. Visit RubyGems.org .Pq Lk https://rubygems.org/ to find the gems you need, and explore GitHub .Pq Lk https://github.com/ to see how they are being developed and used. .El .Pp .Sh OPTIONS The Ruby interpreter accepts the following command-line options (switches). They are quite similar to those of .Xr perl 1 . .Bl -tag -width "1234567890123" -compact .Pp .It Fl -copyright Prints the copyright notice, and quits immediately without running any script. .Pp .It Fl -version Prints the version of the Ruby interpreter, and quits immediately without running any script. .Pp .It Fl 0 Ns Op Ar octal (The digit .Dq zero . ) Specifies the input record separator .Pf ( Li "$/" ) as an octal number. If no digit is given, the null character is taken as the separator. Other switches may follow the digits. .Fl 00 turns Ruby into paragraph mode. .Fl 0777 makes Ruby read whole file at once as a single string since there is no legal character with that value. .Pp .It Fl C Ar directory .It Fl X Ar directory Causes Ruby to switch to the directory. .Pp .It Fl E Ar external Ns Op : Ns Ar internal .It Fl -encoding Ar external Ns Op : Ns Ar internal Specifies the default value(s) for external encodings and internal encoding. Values should be separated with colon (:). .Pp You can omit the one for internal encodings, then the value .Pf ( Li "Encoding.default_internal" ) will be nil. .Pp .It Fl -external-encoding Ns = Ns Ar encoding .It Fl -internal-encoding Ns = Ns Ar encoding Specify the default external or internal character encoding .Pp .It Fl F Ar pattern Specifies input field separator .Pf ( Li "$;" ) . .Pp .It Fl I Ar directory Used to tell Ruby where to load the library scripts. Directory path will be added to the load-path variable .Pf ( Li "$:" ) . .Pp .It Fl K Ar kcode Specifies KANJI (Japanese) encoding. The default value for script encodings .Pf ( Li "__ENCODING__" ) and external encodings ( Li "Encoding.default_external" ) will be the specified one. .Ar kcode can be one of .Bl -hang -offset indent .It Sy e EUC-JP .Pp .It Sy s Windows-31J (CP932) .Pp .It Sy u UTF-8 .Pp .It Sy n ASCII-8BIT (BINARY) .El .Pp .It Fl S Makes Ruby use the .Ev PATH environment variable to search for script, unless its name begins with a slash. This is used to emulate .Li #! on machines that don't support it, in the following manner: .Bd -literal -offset indent #! /usr/local/bin/ruby # This line makes the next one a comment in Ruby \e exec /usr/local/bin/ruby -S $0 $* .Ed .Pp On some systems .Li "$0" does not always contain the full pathname, so you need the .Fl S switch to tell Ruby to search for the script if necessary (to handle embedded spaces and such). A better construct than .Li "$*" would be .Li ${1+"$@"} , but it does not work if the script is being interpreted by .Xr csh 1 . .Pp .It Fl T Ns Op Ar level=1 Turns on taint checks at the specified level (default 1). .Pp .It Fl U Sets the default value for internal encodings .Pf ( Li "Encoding.default_internal" ) to UTF-8. .Pp .It Fl W Ns Op Ar level=2 Turns on verbose mode at the specified level without printing the version message at the beginning. The level can be; .Bl -hang -offset indent .It Sy 0 Verbose mode is "silence". It sets the .Li "$VERBOSE" to nil. .Pp .It Sy 1 Verbose mode is "medium". It sets the .Li "$VERBOSE" to false. .Pp .It Sy 2 (default) Verbose mode is "verbose". It sets the .Li "$VERBOSE" to true. .Fl W Ns 2 is same as .Fl w . .El .Pp .It Fl a Turns on auto-split mode when used with .Fl n or .Fl p . In auto-split mode, Ruby executes .Dl $F = $_.split at beginning of each loop. .Pp .It Fl c Causes Ruby to check the syntax of the script and exit without executing. If there are no syntax errors, Ruby will print .Dq Syntax OK to the standard output. .Pp .It Fl d .It Fl -debug Turns on debug mode. .Li "$DEBUG" will be set to true. .Pp .It Fl e Ar command Specifies script from command-line while telling Ruby not to search the rest of the arguments for a script file name. .Pp .It Fl h .It Fl -help Prints a summary of the options. .Pp .It Fl i Ar extension Specifies in-place-edit mode. The extension, if specified, is added to old file name to make a backup copy. For example: .Bd -literal -offset indent % echo matz > /tmp/junk % cat /tmp/junk matz % ruby -p -i.bak -e '$_.upcase!' /tmp/junk % cat /tmp/junk MATZ % cat /tmp/junk.bak matz .Ed .Pp .It Fl l (The lowercase letter .Dq ell . ) Enables automatic line-ending processing, which means to firstly set .Li "$\e" to the value of .Li "$/" , and secondly chops every line read using .Li chomp! . .Pp .It Fl n Causes Ruby to assume the following loop around your script, which makes it iterate over file name arguments somewhat like .Nm sed .Fl n or .Nm awk . .Bd -literal -offset indent while gets ... end .Ed .Pp .It Fl p Acts mostly same as -n switch, but print the value of variable .Li "$_" at the each end of the loop. For example: .Bd -literal -offset indent % echo matz | ruby -p -e '$_.tr! "a-z", "A-Z"' MATZ .Ed .Pp .It Fl r Ar library Causes Ruby to load the library using require. It is useful when using .Fl n or .Fl p . .Pp .It Fl s Enables some switch parsing for switches after script name but before any file name arguments (or before a .Fl - ) . Any switches found there are removed from .Li ARGV and set the corresponding variable in the script. For example: .Bd -literal -offset indent #! /usr/local/bin/ruby -s # prints "true" if invoked with `-xyz' switch. print "true\en" if $xyz .Ed .Pp .It Fl v Enables verbose mode. Ruby will print its version at the beginning and set the variable .Li "$VERBOSE" to true. Some methods print extra messages if this variable is true. If this switch is given, and no other switches are present, Ruby quits after printing its version. .Pp .It Fl w Enables verbose mode without printing version message at the beginning. It sets the .Li "$VERBOSE" variable to true. .Pp .It Fl x Ns Op Ar directory Tells Ruby that the script is embedded in a message. Leading garbage will be discarded until the first line that starts with .Dq #! and contains the string, .Dq ruby . Any meaningful switches on that line will be applied. The end of the script must be specified with either .Li EOF , .Li "^D" ( Li "control-D" ) , .Li "^Z" ( Li "control-Z" ) , or the reserved word .Li __END__ . If the directory name is specified, Ruby will switch to that directory before executing script. .Pp .It Fl y .It Fl -yydebug DO NOT USE. .Pp Turns on compiler debug mode. Ruby will print a bunch of internal state messages during compilation. Only specify this switch you are going to debug the Ruby interpreter. .Pp .It Fl -disable- Ns Ar FEATURE .It Fl -enable- Ns Ar FEATURE Disables (or enables) the specified .Ar FEATURE . .Bl -tag -width "--disable-rubyopt" -compact .It Fl -disable-gems .It Fl -enable-gems Disables (or enables) RubyGems libraries. By default, Ruby will load the latest version of each installed gem. The .Li Gem constant is true if RubyGems is enabled, false if otherwise. .Pp .It Fl -disable-rubyopt .It Fl -enable-rubyopt Ignores (or considers) the .Ev RUBYOPT environment variable. By default, Ruby considers the variable. .Pp .It Fl -disable-all .It Fl -enable-all Disables (or enables) all features. .Pp .El .Pp .It Fl -dump Ns = Ns Ar target Dump some information. .Pp Prints the specified target. .Ar target can be one of; .Bl -hang -offset indent .It Sy version version description same as .Fl -version .It Sy usage brief usage message same as .Fl h .It Sy help Show long help message same as .Fl -help .It Sy syntax check of syntax same as .Fl c .Fl -yydebug .It Sy yydebug compiler debug mode, same as .Fl -yydebug .Pp Only specify this switch if you are going to debug the Ruby interpreter. .It Sy parsetree .It Sy parsetree_with_comment AST nodes tree .Pp Only specify this switch if you are going to debug the Ruby interpreter. .It Sy insns disassembled instructions .Pp Only specify this switch if you are going to debug the Ruby interpreter. .El .Pp .It Fl -verbose Enables verbose mode without printing version message at the beginning. It sets the .Li "$VERBOSE" variable to true. If this switch is given, and no script arguments (script file or .Fl e options) are present, Ruby quits immediately. .El .Pp .Sh ENVIRONMENT .Bl -tag -width "RUBYSHELL" -compact .It Ev RUBYLIB A colon-separated list of directories that are added to Ruby's library load path .Pf ( Li "$:" ) . Directories from this environment variable are searched before the standard load path is searched. .Pp e.g.: .Dl RUBYLIB="$HOME/lib/ruby:$HOME/lib/rubyext" .Pp .It Ev RUBYOPT Additional Ruby options. .Pp e.g. .Dl RUBYOPT="-w -Ke" .Pp Note that RUBYOPT can contain only .Fl d , Fl E , Fl I , Fl K , Fl r , Fl T , Fl U , Fl v , Fl w , Fl W, Fl -debug , .Fl -disable- Ns Ar FEATURE and .Fl -enable- Ns Ar FEATURE . .Pp .It Ev RUBYPATH A colon-separated list of directories that Ruby searches for Ruby programs when the .Fl S flag is specified. This variable precedes the .Ev PATH environment variable. .Pp .It Ev RUBYSHELL The path to the system shell command. This environment variable is enabled for only mswin32, mingw32, and OS/2 platforms. If this variable is not defined, Ruby refers to .Ev COMSPEC . .Pp .It Ev PATH Ruby refers to the .Ev PATH environment variable on calling Kernel#system. .El .Pp And Ruby depends on some RubyGems related environment variables unless RubyGems is disabled. See the help of .Xr gem 1 as below. .Bd -literal -offset indent % gem help .Ed .Pp .Sh GC ENVIRONMENT The Ruby garbage collector (GC) tracks objects in fixed-sized slots, but each object may have auxiliary memory allocations handled by the malloc family of C standard library calls ( .Xr malloc 3 , .Xr calloc 3 , and .Xr realloc 3 ) . In this documentatation, the "heap" refers to the Ruby object heap of fixed-sized slots, while "malloc" refers to auxiliary allocations commonly referred to as the "process heap". Thus there are at least two possible ways to trigger GC: .Bl -hang -offset indent .It Sy 1 Reaching the object limit. .It Sy 2 Reaching the malloc limit. .Pp .El In Ruby 2.1, the generational GC was introduced and the limits are divided into young and old generations, providing two additional ways to trigger a GC: .Bl -hang -offset indent .It Sy 3 Reaching the old object limit. .It Sy 4 Reaching the old malloc limit. .El .Pp There are currently 4 possible areas where the GC may be tuned by the following 11 environment variables: .Bl -hang -compact -width "RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR" .It Ev RUBY_GC_HEAP_INIT_SLOTS Initial allocation slots. Introduced in Ruby 2.1, default: 10000. .Pp .It Ev RUBY_GC_HEAP_FREE_SLOTS Prepare at least this amount of slots after GC. Allocate this number slots if there are not enough slots. Introduced in Ruby 2.1, default: 4096 .Pp .It Ev RUBY_GC_HEAP_GROWTH_FACTOR Increase allocation rate of heap slots by this factor. Introduced in Ruby 2.1, default: 1.8, minimum: 1.0 (no growth) .Pp .It Ev RUBY_GC_HEAP_GROWTH_MAX_SLOTS Allocation rate is limited to this number of slots, preventing excessive allocation due to RUBY_GC_HEAP_GROWTH_FACTOR. Introduced in Ruby 2.1, default: 0 (no limit) .Pp .It Ev RUBY_GC_HEAP_OLDOBJECT_LIMIT_FACTOR Perform a full GC when the number of old objects is more than R * N, where R is this factor and N is the number of old objects after the last full GC. Introduced in Ruby 2.1.1, default: 2.0 .Pp .It Ev RUBY_GC_MALLOC_LIMIT The initial limit of young generation allocation from the malloc-family. GC will start when this limit is reached. Default: 16MB .Pp .It Ev RUBY_GC_MALLOC_LIMIT_MAX The maximum limit of young generation allocation from malloc before GC starts. Prevents excessive malloc growth due to RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR. Introduced in Ruby 2.1, default: 32MB. .Pp .It Ev RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR Increases the limit of young generation malloc calls, reducing GC frequency but increasing malloc growth until RUBY_GC_MALLOC_LIMIT_MAX is reached. Introduced in Ruby 2.1, default: 1.4, minimum: 1.0 (no growth) .Pp .It Ev RUBY_GC_OLDMALLOC_LIMIT The initial limit of old generation allocation from malloc, a full GC will start when this limit is reached. Introduced in Ruby 2.1, default: 16MB .Pp .It Ev RUBY_GC_OLDMALLOC_LIMIT_MAX The maximum limit of old generation allocation from malloc before a full GC starts. Prevents excessive malloc growth due to RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR. Introduced in Ruby 2.1, default: 128MB .Pp .It Ev RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR Increases the limit of old generation malloc allocation, reducing full GC frequency but increasing malloc growth until RUBY_GC_OLDMALLOC_LIMIT_MAX is reached. Introduced in Ruby 2.1, default: 1.2, minimum: 1.0 (no growth) .Pp .El .Sh STACK SIZE ENVIRONMENT Stack size environment variables are implementation-dependent and subject to change with different versions of Ruby. The VM stack is used for pure-Ruby code and managed by the virtual machine. Machine stack is used by the operating system and its usage is dependent on C extensions as well as C compiler options. Using lower values for these may allow applications to keep more Fibers or Threads running; but increases the chance of SystemStackError exceptions and segmentation faults (SIGSEGV). These environment variables are available since Ruby 2.0.0. All values are specified in bytes. .Pp .Bl -hang -compact -width "RUBY_THREAD_MACHINE_STACK_SIZE" .It Ev RUBY_THREAD_VM_STACK_SIZE VM stack size used at thread creation. default: 131072 (32-bit CPU) or 262144 (64-bit) .Pp .It Ev RUBY_THREAD_MACHINE_STACK_SIZE Machine stack size used at thread creation. default: 524288 or 1048575 .Pp .It Ev RUBY_FIBER_VM_STACK_SIZE VM stack size used at fiber creation. default: 65536 or 131072 .Pp .It Ev RUBY_FIBER_MACHINE_STACK_SIZE Machine stack size used at fiber creation. default: 262144 or 524288 .Pp .El .Sh SEE ALSO .Bl -hang -compact -width "https://www.ruby-toolbox.com/" .It Lk https://www.ruby-lang.org/ The official web site. .It Lk https://www.ruby-toolbox.com/ Comprehensive catalog of Ruby libraries. .El .Pp .Sh REPORTING BUGS .Bl -bullet .It Security vulnerabilities should be reported via an email to .Mt security@ruby-lang.org .

For git gems, a forced checkout will be performed\. . .P For further explanation, \fBbundle pristine\fR ignores unpacked files on disk\. In other words, this command utilizes the local \fB\.gem\fR cache or the gem\'s git repository as if one were installing from scratch\. . .P Note: the Bundler gem cannot be restored to its original state with \fBpristine\fR\. One also cannot use \fBbundle pristine\fR on gems with a \'path\' option in the Gemfile, because bundler has no original copy it can restore from\. . .P When is it practical to use \fBbundle pristine\fR? . .P It comes in handy when a developer is debugging a gem\. \fBbundle pristine\fR is a great way to get rid of experimental changes to a gem that one may not want\. . .P Why use \fBbundle pristine\fR over \fBgem pristine \-\-all\fR? . .P Both commands are very similar\. For context: \fBbundle pristine\fR, without arguments, cleans all gems from the lockfile\. Meanwhile, \fBgem pristine \-\-all\fR cleans all installed gems for that Ruby version\. . .P If a developer forgets which gems in their project they might have been debugging, the Rubygems \fBgem pristine [GEMNAME]\fR command may be inconvenient\. One can avoid waiting for \fBgem pristine \-\-all\fR, and instead run \fBbundle pristine\fR\. man/man1/bundle-binstubs.1 0000644 00000003120 15102661023 0011325 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-BINSTUBS" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-binstubs\fR \- Install the binstubs of the listed gems . .SH "SYNOPSIS" \fBbundle binstubs\fR \fIGEM_NAME\fR [\-\-force] [\-\-path PATH] [\-\-standalone] . .SH "DESCRIPTION" Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it into \fBbin/\fR\. Binstubs are a shortcut\-or alternative\- to always using \fBbundle exec\fR\. This gives you a file that can be run directly, and one that will always run the correct gem version used by the application\. . .P For example, if you run \fBbundle binstubs rspec\-core\fR, Bundler will create the file \fBbin/rspec\fR\. That file will contain enough code to load Bundler, tell it to load the bundled gems, and then run rspec\. . .P This command generates binstubs for executables in \fBGEM_NAME\fR\. Binstubs are put into \fBbin\fR, or the \fB\-\-path\fR directory if one has been set\.

If these options must be remembered, it\'s better to set them using \fBbundle config\fR (e\.g\., \fBbundle config set \-\-local path foo\fR)\. . .P The options that can be configured are: . .TP \fBbin\fR Creates a directory (defaults to \fB~/bin\fR) and place any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\. . .TP \fBdeployment\fR In deployment mode, Bundler will \'roll\-out\' the bundle for \fBproduction\fR use\. Please check carefully if you want to have this option enabled in \fBdevelopment\fR or \fBtest\fR environments\. . .TP \fBpath\fR The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\. . .TP \fBwithout\fR A space\-separated list of groups referencing gems to skip during installation\. . .TP \fBwith\fR A space\-separated list of groups referencing gems to include during installation\. . .SH "BUILD OPTIONS" You can use \fBbundle config\fR to give Bundler the flags to pass to the gem installer every time bundler tries to install a particular gem\. . .P A very common example, the \fBmysql\fR gem, requires Snow Leopard users to pass configuration flags to \fBgem install\fR to specify where to find the \fBmysql_config\fR executable\. . .IP "" 4 . .nf gem install mysql \-\- \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config . .fi . .IP "" 0 . .P Since the specific location of that executable can change from machine to machine, you can specify these flags on a per\-machine basis\. . .IP "" 4 . .nf bundle config set \-\-global build\.mysql \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config . .fi . .IP "" 0 . .P After running this command, every time bundler needs to install the \fBmysql\fR gem, it will pass along the flags you specified\. . .SH "CONFIGURATION KEYS" Configuration keys in bundler have two forms: the canonical form and the environment variable form\. . .P For instance, passing the \fB\-\-without\fR flag to bundle install(1) \fIbundle\-install\.1\.html\fR prevents Bundler from installing certain groups specified in the Gemfile(5)\. Bundler persists this value in \fBapp/\.bundle/config\fR so that calls to \fBBundler\.setup\fR do not try to find gems from the \fBGemfile\fR that you didn\'t install\. Additionally, subsequent calls to bundle install(1) \fIbundle\-install\.1\.html\fR remember this setting and skip those groups\. . .P The canonical form of this configuration is \fB"without"\fR\. To convert the canonical form to the environment variable form, capitalize it, and prepend \fBBUNDLE_\fR\. The environment variable form of \fB"without"\fR is \fBBUNDLE_WITHOUT\fR\. . .P Any periods in the configuration keys must be replaced with two underscores when setting it via environment variables\. The configuration key \fBlocal\.rack\fR becomes the environment variable \fBBUNDLE_LOCAL__RACK\fR\. . .SH "LIST OF AVAILABLE KEYS" The following is a list of all configuration keys and their purpose\.

If you use both, environment variables will take preference over global settings\. . .SH "LOCAL GIT REPOS" Bundler also allows you to work against a git repository locally instead of using the remote version\. This can be achieved by setting up a local override: . .IP "" 4 . .nf bundle config set \-\-local local\.GEM_NAME /path/to/local/git/repository . .fi . .IP "" 0 . .P For example, in order to use a local Rack repository, a developer could call: . .IP "" 4 . .nf bundle config set \-\-local local\.rack ~/Work/git/rack . .fi . .IP "" 0 . .P Now instead of checking out the remote git repository, the local override will be used\. Similar to a path source, every time the local git repository change, changes will be automatically picked up by Bundler\. This means a commit in the local git repo will update the revision in the \fBGemfile\.lock\fR to the local git repo revision\. This requires the same attention as git submodules\. Before pushing to the remote, you need to ensure the local override was pushed, otherwise you may point to a commit that only exists in your local machine\. You\'ll also need to CGI escape your usernames and passwords as well\. . .P Bundler does many checks to ensure a developer won\'t work with invalid references\. Particularly, we force a developer to specify a branch in the \fBGemfile\fR in order to use this feature\. If the branch specified in the \fBGemfile\fR and the current branch in the local git repository do not match, Bundler will abort\. This ensures that a developer is always working against the correct branches, and prevents accidental locking to a different branch\. . .P Finally, Bundler also ensures that the current revision in the \fBGemfile\.lock\fR exists in the local git repository\. By doing this, Bundler forces you to fetch the latest changes in the remotes\. . .SH "MIRRORS OF GEM SOURCES" Bundler supports overriding gem sources with mirrors\. This allows you to configure rubygems\.org as the gem source in your Gemfile while still using your mirror to fetch gems\. . .IP "" 4 . .nf bundle config set \-\-global mirror\.SOURCE_URL MIRROR_URL . .fi . .IP "" 0 . .P For example, to use a mirror of rubygems\.org hosted at rubygems\-mirror\.org: . .IP "" 4 . .nf bundle config set \-\-global mirror\.http://rubygems\.org http://rubygems\-mirror\.org . .fi . .IP "" 0 . .P Each mirror also provides a fallback timeout setting\. If the mirror does not respond within the fallback timeout, Bundler will try to use the original server instead of the mirror\. . .IP "" 4 . .nf bundle config set \-\-global mirror\.SOURCE_URL\.fallback_timeout TIMEOUT . .fi . .IP "" 0 . .P For example, to fall back to rubygems\.org after 3 seconds: . .IP "" 4 . .nf bundle config set \-\-global mirror\.https://rubygems\.org\.fallback_timeout 3 . .fi . .IP "" 0 . .P The default fallback timeout is 0\.1 seconds, but the setting can currently only accept whole seconds (for example, 1, 15, or 30)\. . .SH "CREDENTIALS FOR GEM SOURCES" Bundler allows you to configure credentials for any gem source, which allows you to avoid putting secrets into your Gemfile\. . .IP "" 4 . .nf bundle config set \-\-global SOURCE_HOSTNAME USERNAME:PASSWORD . .fi . .IP "" 0 . .P For example, to save the credentials of user \fBclaudette\fR for the gem source at \fBgems\.longerous\.com\fR, you would run: . .IP "" 4 . .nf bundle config set \-\-global gems\.longerous\.com claudette:s00pers3krit . .fi . .IP "" 0 . .P Or you can set the credentials as an environment variable like this: . .IP "" 4 . .nf export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit" . .fi . .IP "" 0 . .P For gems with a git source with HTTP(S) URL you can specify credentials like so: . .IP "" 4 . .nf bundle config set \-\-global https://github\.com/rubygems/rubygems\.git username:password . .fi . .IP "" 0 . .P Or you can set the credentials as an environment variable like so: . .IP "" 4 . .nf export BUNDLE_GITHUB__COM=username:password . .fi . .IP "" 0 . .P This is especially useful for private repositories on hosts such as Github, where you can use personal OAuth tokens: . .IP "" 4 . .nf export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x\-oauth\-basic . .fi . .IP "" 0 . .P Note that any configured credentials will be redacted by informative commands such as \fBbundle config list\fR or \fBbundle config get\fR, unless you use the \fB\-\-parseable\fR flag\. This is to avoid unintentionally leaking credentials when copy\-pasting bundler output\. . .P Also note that to guarantee a sane mapping between valid environment variable names and valid host names, bundler makes the following transformations: . .IP "\(bu" 4 Any \fB\-\fR characters in a host name are mapped to a triple dash (\fB___\fR) in the corresponding environment variable\. . .IP "\(bu" 4 Any \fB\.\fR characters in a host name are mapped to a double dash (\fB__\fR) in the corresponding environment variable\. . .IP "" 0 . .P This means that if you have a gem server named \fBmy\.gem\-host\.com\fR, you\'ll need to use the \fBBUNDLE_MY__GEM___HOST__COM\fR variable to configure credentials for it through ENV\. . .SH "CONFIGURE BUNDLER DIRECTORIES" Bundler\'s home, config, cache and plugin directories are able to be configured through environment variables\. The default location for Bundler\'s home directory is \fB~/\.bundle\fR, which all directories inherit from by default\. The following outlines the available environment variables and their default values . .IP "" 4 . .nf BUNDLE_USER_HOME : $HOME/\.bundle BUNDLE_USER_CACHE : $BUNDLE_USER_HOME/cache BUNDLE_USER_CONFIG : $BUNDLE_USER_HOME/config BUNDLE_USER_PLUGIN : $BUNDLE_USER_HOME/plugin . .fi . .IP "" 0 man/man1/bundle-cache.1 0000644 00000006304 15102661023 0010546 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-CACHE" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-cache\fR \- Package your needed \fB\.gem\fR files into your application . .SH "SYNOPSIS" \fBbundle cache\fR . .SH "DESCRIPTION" Copy all of the \fB\.gem\fR files needed to run the application into the \fBvendor/cache\fR directory\.

This needs to be explicitly enabled via the \fB\-\-all\fR option\. Once used, the \fB\-\-all\fR option will be remembered\. . .SH "SUPPORT FOR MULTIPLE PLATFORMS" When using gems that have different packages for different platforms, Bundler supports caching of gems for other platforms where the Gemfile has been resolved (i\.e\. present in the lockfile) in \fBvendor/cache\fR\. This needs to be enabled via the \fB\-\-all\-platforms\fR option\. This setting will be remembered in your local bundler configuration\. . .SH "REMOTE FETCHING" By default, if you run \fBbundle install(1)\fR](bundle\-install\.1\.html) after running bundle cache(1) \fIbundle\-cache\.1\.html\fR, bundler will still connect to \fBrubygems\.org\fR to check whether a platform\-specific gem exists for any of the gems in \fBvendor/cache\fR\. . .P For instance, consider this Gemfile(5): . .IP "" 4 . .nf source "https://rubygems\.org" gem "nokogiri" . .fi . .IP "" 0 . .P If you run \fBbundle cache\fR under C Ruby, bundler will retrieve the version of \fBnokogiri\fR for the \fB"ruby"\fR platform\. If you deploy to JRuby and run \fBbundle install\fR, bundler is forced to check to see whether a \fB"java"\fR platformed \fBnokogiri\fR exists\. . .P Even though the \fBnokogiri\fR gem for the Ruby platform is \fItechnically\fR acceptable on JRuby, it has a C extension that does not run on JRuby\. As a result, bundler will, by default, still connect to \fBrubygems\.org\fR to check whether it has a version of one of your gems more specific to your platform\. . .P This problem is also not limited to the \fB"java"\fR platform\. A similar (common) problem can happen when developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux\. . .P If you know for sure that the gems packaged in \fBvendor/cache\fR are appropriate for the platform you are on, you can run \fBbundle install \-\-local\fR to skip checking for more appropriate gems, and use the ones in \fBvendor/cache\fR\. . .P One way to be sure that you have the right platformed versions of all your gems is to run \fBbundle cache\fR on an identical machine and check in the gems\. For instance, you can run \fBbundle cache\fR on an identical staging box during your staging process, and check in the \fBvendor/cache\fR before deploying to production\. . .P By default, bundle cache(1) \fIbundle\-cache\.1\.html\fR fetches and also installs the gems to the default location\.

If this is the first time you run bundle install (and a \fBGemfile\.lock\fR does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems\. . .P If a \fBGemfile\.lock\fR does exist, and you have not updated your Gemfile(5), Bundler will fetch all remote sources, but use the dependencies specified in the \fBGemfile\.lock\fR instead of resolving dependencies\. . .P If a \fBGemfile\.lock\fR does exist, and you have updated your Gemfile(5), Bundler will use the dependencies in the \fBGemfile\.lock\fR for all gems that you did not update, but will re\-resolve the dependencies of gems that you did update\. You can find more information about this update process below under \fICONSERVATIVE UPDATING\fR\. . .SH "OPTIONS" The \fB\-\-clean\fR, \fB\-\-deployment\fR, \fB\-\-frozen\fR, \fB\-\-no\-prune\fR, \fB\-\-path\fR, \fB\-\-shebang\fR, \fB\-\-system\fR, \fB\-\-without\fR and \fB\-\-with\fR options are deprecated because they only make sense if they are applied to every subsequent \fBbundle install\fR run automatically and that requires \fBbundler\fR to silently remember them\. Since \fBbundler\fR will no longer remember CLI flags in future versions, \fBbundle config\fR (see bundle\-config(1)) should be used to apply them permanently\. . .TP \fB\-\-binstubs[=<directory>]\fR Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it in \fBbin/\fR\. This lets you link the binstub inside of an application to the exact gem version the application needs\. . .IP Creates a directory (defaults to \fB~/bin\fR) and places any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\. . .TP \fB\-\-clean\fR On finishing the installation Bundler is going to remove any gems not present in the current Gemfile(5)\. Don\'t worry, gems currently in use will not be removed\. . .IP This option is deprecated in favor of the \fBclean\fR setting\. . .TP \fB\-\-deployment\fR In \fIdeployment mode\fR, Bundler will \'roll\-out\' the bundle for production or CI use\. Please check carefully if you want to have this option enabled in your development environment\. . .IP This option is deprecated in favor of the \fBdeployment\fR setting\. . .TP \fB\-\-redownload\fR Force download every gem, even if the required versions are already available locally\. . .TP \fB\-\-frozen\fR Do not allow the Gemfile\.lock to be updated after this install\. Exits non\-zero if there are going to be changes to the Gemfile\.lock\. . .IP This option is deprecated in favor of the \fBfrozen\fR setting\. . .TP \fB\-\-full\-index\fR Bundler will not call Rubygems\' API endpoint (default) but download and cache a (currently big) index file of all gems\. Performance can be improved for large bundles that seldom change by enabling this option\. . .TP \fB\-\-gemfile=<gemfile>\fR The location of the Gemfile(5) which Bundler should use\. This defaults to a Gemfile(5) in the current working directory\. In general, Bundler will assume that the location of the Gemfile(5) is also the project\'s root and will try to find \fBGemfile\.lock\fR and \fBvendor/cache\fR relative to this location\. . .TP \fB\-\-jobs=[<number>]\fR, \fB\-j[<number>]\fR The maximum number of parallel download and install jobs\. The default is \fB1\fR\. . .TP \fB\-\-local\fR Do not attempt to connect to \fBrubygems\.org\fR\. Instead, Bundler will use the gems already present in Rubygems\' cache or in \fBvendor/cache\fR\. Note that if an appropriate platform\-specific gem exists on \fBrubygems\.org\fR it will not be found\. . .TP \fB\-\-no\-cache\fR Do not update the cache in \fBvendor/cache\fR with the newly bundled gems\. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install\. . .TP \fB\-\-no\-prune\fR Don\'t remove stale gems from the cache when the installation finishes\. . .IP This option is deprecated in favor of the \fBno_prune\fR setting\. . .TP \fB\-\-path=<path>\fR The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\. . .IP This option is deprecated in favor of the \fBpath\fR setting\. . .TP \fB\-\-quiet\fR Do not print progress information to the standard output\. Instead, Bundler will exit using a status code (\fB$?\fR)\. . .TP \fB\-\-retry=[<number>]\fR Retry failed network or git requests for \fInumber\fR times\. . .TP \fB\-\-shebang=<ruby\-executable>\fR Uses the specified ruby executable (usually \fBruby\fR) to execute the scripts created with \fB\-\-binstubs\fR\. In addition, if you use \fB\-\-binstubs\fR together with \fB\-\-shebang jruby\fR these executables will be changed to execute \fBjruby\fR instead\. . .IP This option is deprecated in favor of the \fBshebang\fR setting\. . .TP \fB\-\-standalone[=<list>]\fR Makes a bundle that can work without depending on Rubygems or Bundler at runtime\. A space separated list of groups to install has to be specified\. Bundler creates a directory named \fBbundle\fR and installs the bundle there\. It also generates a \fBbundle/bundler/setup\.rb\fR file to replace Bundler\'s own setup in the manner required\. Using this option implicitly sets \fBpath\fR, which is a [remembered option][REMEMBERED OPTIONS]\. . .TP \fB\-\-system\fR Installs the gems specified in the bundle to the system\'s Rubygems location\. This overrides any previous configuration of \fB\-\-path\fR\. . .IP This option is deprecated in favor of the \fBsystem\fR setting\. . .TP \fB\-\-trust\-policy=[<policy>]\fR Apply the Rubygems security policy \fIpolicy\fR, where policy is one of \fBHighSecurity\fR, \fBMediumSecurity\fR, \fBLowSecurity\fR, \fBAlmostNoSecurity\fR, or \fBNoSecurity\fR\. For more details, please see the Rubygems signing documentation linked below in \fISEE ALSO\fR\. . .TP \fB\-\-with=<list>\fR A space\-separated list of groups referencing gems to install\. If an optional group is given it is installed\. If a group is given that is in the remembered list of groups given to \-\-without, it is removed from that list\. . .IP This option is deprecated in favor of the \fBwith\fR setting\. . .TP \fB\-\-without=<list>\fR A space\-separated list of groups referencing gems to skip during installation\. If a group is given that is in the remembered list of groups given to \-\-with, it is removed from that list\. . .IP This option is deprecated in favor of the \fBwithout\fR setting\. . .SH "DEPLOYMENT MODE" Bundler\'s defaults are optimized for development\. To switch to defaults optimized for deployment and for CI, use the \fB\-\-deployment\fR flag\. Do not activate deployment mode on development machines, as it will cause an error when the Gemfile(5) is modified\. . .IP "1." 4 A \fBGemfile\.lock\fR is required\. . .IP To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a \fBGemfile\.lock\fR is required\. . .IP This is mainly to ensure that you remember to check your \fBGemfile\.lock\fR into version control\. . .IP "2." 4 The \fBGemfile\.lock\fR must be up to date . .IP In development, you can modify your Gemfile(5) and re\-run \fBbundle install\fR to \fIconservatively update\fR your \fBGemfile\.lock\fR snapshot\. . .IP In deployment, your \fBGemfile\.lock\fR should be up\-to\-date with changes made in your Gemfile(5)\. . .IP "3." 4 Gems are installed to \fBvendor/bundle\fR not your default system location . .IP In development, it\'s convenient to share the gems used in your application with other applications and other scripts that run on the system\. . .IP In deployment, isolation is a more important default\. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them\. . .IP As a result, \fBbundle install \-\-deployment\fR installs gems to the \fBvendor/bundle\fR directory in the application\. This may be overridden using the \fB\-\-path\fR option\. . .IP "" 0 . .SH "SUDO USAGE" By default, Bundler installs gems to the same location as \fBgem install\fR\. . .P In some cases, that location may not be writable by your Unix user\. In that case, Bundler will stage everything in a temporary directory, then ask you for your \fBsudo\fR password in order to copy the gems into their system location\. . .P From your perspective, this is identical to installing the gems directly into the system\. . .P You should never use \fBsudo bundle install\fR\. This is because several other steps in \fBbundle install\fR must be performed as the current user: . .IP "\(bu" 4 Updating your \fBGemfile\.lock\fR . .IP "\(bu" 4 Updating your \fBvendor/cache\fR, if necessary . .IP "\(bu" 4 Checking out private git repositories using your user\'s SSH keys . .IP "" 0 . .P Of these three, the first two could theoretically be performed by \fBchown\fRing the resulting files to \fB$SUDO_USER\fR\. The third, however, can only be performed by invoking the \fBgit\fR command as the current user\. Therefore, git gems are downloaded and installed into \fB~/\.bundle\fR rather than $GEM_HOME or $BUNDLE_PATH\. . .P As a result, you should run \fBbundle install\fR as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location\. . .SH "INSTALLING GROUPS" By default, \fBbundle install\fR will install all gems in all groups in your Gemfile(5), except those declared for a different platform\. . .P However, you can explicitly tell Bundler to skip installing certain groups with the \fB\-\-without\fR option\. This option takes a space\-separated list of groups\. . .P While the \fB\-\-without\fR option will skip \fIinstalling\fR the gems in the specified groups, it will still \fIdownload\fR those gems and use them to resolve the dependencies of every gem in your Gemfile(5)\. . .P This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against\. . .P \fBBundler offers a rock\-solid guarantee that the third\-party code you are running in development and testing is also the third\-party code you are running in production\. You can choose to exclude some of that code in different environments, but you will never be caught flat\-footed by different versions of third\-party code being used in different environments\.\fR . .P For a simple illustration, consider the following Gemfile(5): . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'sinatra\' group :production do gem \'rack\-perftools\-profiler\' end . .fi . .IP "" 0 . .P In this case, \fBsinatra\fR depends on any version of Rack (\fB>= 1\.0\fR), while \fBrack\-perftools\-profiler\fR depends on 1\.x (\fB~> 1\.0\fR)\. . .P When you run \fBbundle install \-\-without production\fR in development, we look at the dependencies of \fBrack\-perftools\-profiler\fR as well\. That way, you do not spend all your time developing against Rack 2\.0, using new APIs unavailable in Rack 1\.x, only to have Bundler switch to Rack 1\.2 when the \fBproduction\fR group \fIis\fR used\. . .P This should not cause any problems in practice, because we do not attempt to \fBinstall\fR the gems in the excluded groups, and only evaluate as part of the dependency resolution process\. . .P This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production\. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using\. . .SH "THE GEMFILE\.LOCK" When you run \fBbundle install\fR, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called \fBGemfile\.lock\fR\. . .P Bundler uses this file in all subsequent calls to \fBbundle install\fR, which guarantees that you always use the same exact code, even as your application moves across machines\. . .P Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point\-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies\. . .P As a result, you \fBSHOULD\fR check your \fBGemfile\.lock\fR into version control, in both applications and gems\. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third\-party code being used if \fBany\fR of the gems in the Gemfile(5) or any of their dependencies have been updated\. . .P When Bundler first shipped, the \fBGemfile\.lock\fR was included in the \fB\.gitignore\fR file included with generated gems\. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem\. Since \fBbundle install\fR is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing\. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems\. . .SH "CONSERVATIVE UPDATING" When you make a change to the Gemfile(5) and then run \fBbundle install\fR, Bundler will update only the gems that you modified\. . .P In other words, if a gem that you \fBdid not modify\fR worked before you called \fBbundle install\fR, it will continue to use the exact same versions of all dependencies as it used before the update\. . .P Let\'s take a look at an example\. Here\'s your original Gemfile(5): . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'actionpack\', \'2\.3\.8\' gem \'activemerchant\' . .fi . .IP "" 0 . .P In this case, both \fBactionpack\fR and \fBactivemerchant\fR depend on \fBactivesupport\fR\. The \fBactionpack\fR gem depends on \fBactivesupport 2\.3\.8\fR and \fBrack ~> 1\.1\.0\fR, while the \fBactivemerchant\fR gem depends on \fBactivesupport >= 2\.3\.2\fR, \fBbraintree >= 2\.0\.0\fR, and \fBbuilder >= 2\.0\.0\fR\. . .P When the dependencies are first resolved, Bundler will select \fBactivesupport 2\.3\.8\fR, which satisfies the requirements of both gems in your Gemfile(5)\. . .P Next, you modify your Gemfile(5) to: . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'actionpack\', \'3\.0\.0\.rc\' gem \'activemerchant\' . .fi . .IP "" 0 . .P The \fBactionpack 3\.0\.0\.rc\fR gem has a number of new dependencies, and updates the \fBactivesupport\fR dependency to \fB= 3\.0\.0\.rc\fR and the \fBrack\fR dependency to \fB~> 1\.2\.1\fR\. . .P When you run \fBbundle install\fR, Bundler notices that you changed the \fBactionpack\fR gem, but not the \fBactivemerchant\fR gem\. It evaluates the gems currently being used to satisfy its requirements: . .TP \fBactivesupport 2\.3\.8\fR also used to satisfy a dependency in \fBactivemerchant\fR, which is not being updated . .TP \fBrack ~> 1\.1\.0\fR not currently being used to satisfy another dependency . .P Because you did not explicitly ask to update \fBactivemerchant\fR, you would not expect it to suddenly stop working after updating \fBactionpack\fR\. However, satisfying the new \fBactivesupport 3\.0\.0\.rc\fR dependency of actionpack requires updating one of its dependencies\. . .P Even though \fBactivemerchant\fR declares a very loose dependency that theoretically matches \fBactivesupport 3\.0\.0\.rc\fR, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies\. In this case, the \fBactivemerchant\fR dependency is treated as \fBactivemerchant 1\.7\.1 + activesupport 2\.3\.8\fR, so \fBbundle install\fR will report that it cannot update \fBactionpack\fR\. . .P To explicitly update \fBactionpack\fR, including its dependencies which other gems in the Gemfile(5) still depend on, run \fBbundle update actionpack\fR (see \fBbundle update(1)\fR)\. . .P \fBSummary\fR: In general, after making a change to the Gemfile(5) , you should first try to run \fBbundle install\fR, which will guarantee that no other gem in the Gemfile(5) is impacted by the change\. If that does not work, run bundle update(1) \fIbundle\-update\.1\.html\fR\. . .SH "SEE ALSO" . .IP "\(bu" 4 Gem install docs \fIhttp://guides\.rubygems\.org/rubygems\-basics/#installing\-gems\fR . .IP "\(bu" 4 Rubygems signing docs \fIhttp://guides\.rubygems\.org/security/\fR . .IP "" 0 man/man1/bundle-outdated.1 0000644 00000007346 15102661023 0011323 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-OUTDATED" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-outdated\fR \- List installed gems with newer versions available . .SH "SYNOPSIS" \fBbundle outdated\fR [GEM] [\-\-local] [\-\-pre] [\-\-source] [\-\-strict] [\-\-parseable | \-\-porcelain] [\-\-group=GROUP] [\-\-groups] [\-\-update\-strict] [\-\-patch|\-\-minor|\-\-major] [\-\-filter\-major] [\-\-filter\-minor] [\-\-filter\-patch] [\-\-only\-explicit] . .SH "DESCRIPTION" Outdated lists the names and versions of gems that have a newer version available in the given source\.

Actions in a Rakefile are specified in a code block. (Usually delimited by +do+/+end+ pairs.) execute :: When a task is executed, all of its actions are performed in the order they were defined. Note that, unlike <tt>invoke</tt>, <tt>execute</tt> always executes the actions (without invoking or executing the prerequisites). file task (Rake::FileTask) :: A file task is a task whose purpose is to create a file (which has the same name as the task). When invoked, a file task will only execute if one or more of the following conditions are true. 1. The associated file does not exist. 2. A prerequisite has a later time stamp than the existing file. Because normal Tasks always have the current time as timestamp, a FileTask that has a normal Task prerequisite will always execute. invoke :: When a task is invoked, first we check to see if it has been invoked before. If it has been, then nothing else is done. If this is the first time it has been invoked, then we invoke each of its prerequisites. Finally, we check to see if we need to execute the actions of this task by calling Rake::Task#needed?. If the task is needed, we execute its actions. NOTE: Prerequisites are still invoked even if the task is not needed. prerequisites :: Every task has a (possibly empty) set of prerequisites.

Ok, let me state from the beginning that I never intended to write this code. I'm not convinced it is useful, and I'm not convinced anyone would even be interested in it. All I can say is that Why's onion truck must by been passing through the Ohio valley. What am I talking about? ... A Ruby version of Make. See, I can sense you cringing already, and I agree. The world certainly doesn't need yet another reworking of the "make" program. I mean, we already have "ant". Isn't that enough? It started yesterday. I was helping a coworker fix a problem in one of the Makefiles we use in our project. Not a particularly tough problem, but during the course of the conversation I began lamenting some of the shortcomings of make. In particular, in one of my makefiles I wanted to determine the name of a file dynamically and had to resort to some simple scripting (in Ruby) to make it work. "Wouldn't it be nice if you could just use Ruby inside a Makefile" I said. My coworker (a recent convert to Ruby) agreed, but wondered what it would look like. So I sketched the following on the whiteboard... "What if you could specify the make tasks in Ruby, like this ..." task "build" do java_compile(...args, etc ...) end "The task function would register "build" as a target to be made, and the block would be the action executed whenever the build system determined that it was time to do the build target." We agreed that would be cool, but writing make from scratch would be WAY too much work. And that was the end of that! ... Except I couldn't get the thought out of my head. What exactly would be needed to make the about syntax work as a make file? Hmmm, you would need to register the tasks, you need some way of specifying dependencies between tasks, and some way of kicking off the process. Hey! What if we did ... and fifteen minutes later I had a working prototype of Ruby make, complete with dependencies and actions. I showed the code to my coworker and we had a good laugh. It was just about a page worth of code that reproduced an amazing amount of the functionality of make. We were both truly stunned with the power of Ruby. But it didn't do everything make did. In particular, it didn't have timestamp based file dependencies (where a file is rebuilt if any of its prerequisite files have a later timestamp). Obviously THAT would be a pain to add and so Ruby Make would remain an interesting experiment. ... Except as I walked back to my desk, I started thinking about what file based dependencies would really need. Rats! I was hooked again, and by adding a new class and two new methods, file/timestamp dependencies were implemented. Ok, now I was really hooked. Last night (during CSI!) I massaged the code and cleaned it up a bit. The result is a bare-bones replacement for make in exactly 100 lines of code. For the curious, you can see it at ... * doc/proto_rake.rdoc Oh, about the name. When I wrote the example Ruby Make task on my whiteboard, my coworker exclaimed "Oh! I have the perfect name: Rake ... Get it? Ruby-Make. Rake!" He said he envisioned the tasks as leaves and Rake would clean them up ... or something like that. Anyways, the name stuck. Some quick examples ... A simple task to delete backup files ... task :clean do Dir['*~'].each {|fn| rm fn rescue nil} end Note that task names are symbols (they are slightly easier to type than quoted strings ... but you may use quoted string if you would rather). Rake makes the methods of the FileUtils module directly available, so we take advantage of the <tt>rm</tt> command. Also note the use of "rescue nil" to trap and ignore errors in the <tt>rm</tt> command. To run it, just type "rake clean". Rake will automatically find a Rakefile in the current directory (or above!) and will invoke the targets named on the command line. If there are no targets explicitly named, rake will invoke the task "default". Here's another task with dependencies ... task :clobber => [:clean] do rm_r "tempdir" end Task :clobber depends upon task :clean, so :clean will be run before :clobber is executed. Files are specified by using the "file" command. It is similar to the task command, except that the task name represents a file, and the task will be run only if the file doesn't exist, or if its modification time is earlier than any of its prerequisites. Here is a file based dependency that will compile "hello.cc" to "hello.o". file "hello.cc" file "hello.o" => ["hello.cc"] do |t| srcfile = t.name.sub(/\.o$/, ".cc") sh %{g++ #{srcfile} -c -o #{t.name}} end I normally specify file tasks with string (rather than symbols). Some file names can't be represented by symbols. Plus it makes the distinction between them more clear to the casual reader. Currently writing a task for each and every file in the project would be tedious at best. I envision a set of libraries to make this job easier. For instance, perhaps something like this ... require 'rake/ctools' Dir['*.c'].each do |fn| c_source_file(fn) end where "c_source_file" will create all the tasks need to compile all the C source files in a directory. Any number of useful libraries could be created for rake. That's it. There's no documentation (other than whats in this message). Does this sound interesting to anyone? If so, I'll continue to clean it up and write it up and publish it on RAA. Otherwise, I'll leave it as an interesting exercise and a tribute to the power of Ruby. Why /might/ rake be interesting to Ruby programmers. I don't know, perhaps ... * No weird make syntax (only weird Ruby syntax :-) * No need to edit or read XML (a la ant) * Platform independent build scripts. * Will run anywhere Ruby exists, so no need to have "make" installed. If you stay away from the "sys" command and use things like 'ftools', you can have a perfectly platform independent build script. Also rake is only 100 lines of code, so it can easily be packaged along with the rest of your code. So ... Sorry for the long rambling message. Like I said, I never intended to write this code at all. gems/gems/rake-13.0.3/doc/rakefile.rdoc 0000644 00000050342 15102661023 0013274 0 ustar 00 = Rakefile Format First of all, there is no special format for a Rakefile. A Rakefile contains executable Ruby code. Anything legal in a ruby script is allowed in a Rakefile. Now that we understand there is no special syntax in a Rakefile, there are some conventions that are used in a Rakefile that are a little unusual in a typical Ruby program. Since a Rakefile is tailored to specifying tasks and actions, the idioms used in a Rakefile are designed to support that. So, what goes into a Rakefile? == Tasks Tasks are the main unit of work in a Rakefile. Tasks have a name (usually given as a symbol or a string), a list of prerequisites (more symbols or strings) and a list of actions (given as a block). === Simple Tasks A task is declared by using the +task+ method. +task+ takes a single parameter that is the name of the task. task :name === Tasks with Prerequisites Any prerequisites are given as a list (enclosed in square brackets) following the name and an arrow (=>). task name: [:prereq1, :prereq2] *NOTE:* Although this syntax looks a little funky, it is legal Ruby. We are constructing a hash where the key is :name and the value for that key is the list of prerequisites. It is equivalent to the following ... hash = Hash.new hash[:name] = [:prereq1, :prereq2] task(hash) You can also use strings for task names and prerequisites, rake doesn't care. This is the same task definition: task 'name' => %w[prereq1 prereq2] As is this: task name: %w[prereq1 prereq2] We'll prefer this style for regular tasks with prerequisites throughout the rest of the document. Using an array of strings for the prerequisites means you will need to make fewer changes if you need to move tasks into namespaces or perform other refactorings. === Tasks with Actions Actions are defined by passing a block to the +task+ method. Any Ruby code can be placed in the block. The block may reference the task object via the block parameter. task name: [:prereq1, :prereq2] do |t| # actions (may reference t) end === Multiple Definitions A task may be specified more than once. Each specification adds its prerequisites and actions to the existing definition. This allows one part of a rakefile to specify the actions and a different rakefile (perhaps separately generated) to specify the dependencies. For example, the following is equivalent to the single task specification given above. task :name task name: :prereq1 task name: %w[prereq2] task :name do |t| # actions end == File Tasks Some tasks are designed to create a file from one or more other files. Tasks that generate these files may be skipped if the file already exists. File tasks are used to specify file creation tasks. File tasks are declared using the +file+ method (instead of the +task+ method). In addition, file tasks are usually named with a string rather than a symbol. The following file task creates a executable program (named +prog+) given two object files named +a.o+ and +b.o+. The tasks for creating +a.o+ and +b.o+ are not shown. file "prog" => ["a.o", "b.o"] do |t| sh "cc -o #{t.name} #{t.prerequisites.join(' ')}" end == Directory Tasks It is common to need to create directories upon demand. The +directory+ convenience method is a short-hand for creating a FileTask that creates the directory. For example, the following declaration ... directory "testdata/examples/doc" is equivalent to ... file "testdata" do |t| mkdir t.name end file "testdata/examples" => ["testdata"] do |t| mkdir t.name end file "testdata/examples/doc" => ["testdata/examples"] do |t| mkdir t.name end The +directory+ method does not accept prerequisites or actions, but both prerequisites and actions can be added later. For example ... directory "testdata" file "testdata" => ["otherdata"] file "testdata" do cp Dir["standard_data/*.data"], "testdata" end == Tasks with Parallel Prerequisites Rake allows parallel execution of prerequisites using the following syntax: multitask copy_files: %w[copy_src copy_doc copy_bin] do puts "All Copies Complete" end In this example, +copy_files+ is a normal rake task. Its actions are executed whenever all of its prerequisites are done. The big difference is that the prerequisites (+copy_src+, +copy_bin+ and +copy_doc+) are executed in parallel. Each of the prerequisites are run in their own Ruby thread, possibly allowing faster overall runtime. === Secondary Prerequisites If any of the primary prerequisites of a multitask have common secondary prerequisites, all of the primary/parallel prerequisites will wait until the common prerequisites have been run. For example, if the <tt>copy_<em>xxx</em></tt> tasks have the following prerequisites: task copy_src: :prep_for_copy task copy_bin: :prep_for_copy task copy_doc: :prep_for_copy Then the +prep_for_copy+ task is run before starting all the copies in parallel. Once +prep_for_copy+ is complete, +copy_src+, +copy_bin+, and +copy_doc+ are all run in parallel. Note that +prep_for_copy+ is run only once, even though it is referenced in multiple threads. === Thread Safety The Rake internal data structures are thread-safe with respect to the multitask parallel execution, so there is no need for the user to do extra synchronization for Rake's benefit. However, if there are user data structures shared between the parallel prerequisites, the user must do whatever is necessary to prevent race conditions. == Tasks with Arguments Prior to version 0.8.0, rake was only able to handle command line arguments of the form NAME=VALUE that were passed into Rake via the ENV hash. Many folks had asked for some kind of simple command line arguments, perhaps using "--" to separate regular task names from argument values on the command line. The problem is that there was no easy way to associate positional arguments on the command line with different tasks. Suppose both tasks :a and :b expect a command line argument: does the first value go with :a? What if :b is run first? Should it then get the first command line argument. Rake 0.8.0 solves this problem by explicitly passing values directly to the tasks that need them. For example, if I had a release task that required a version number, I could say: rake release[0.8.2] And the string "0.8.2" will be passed to the :release task. Multiple arguments can be passed by separating them with a comma, for example: rake name[john,doe] Just a few words of caution. The rake task name and its arguments need to be a single command line argument to rake. This generally means no spaces. If spaces are needed, then the entire name + argument string should be quoted. Something like this: rake "name[billy bob, smith]" (Quoting rules vary between operating systems and shells, so make sure you consult the proper docs for your OS/shell). === Tasks that Expect Parameters Parameters are only given to tasks that are setup to expect them. In order to handle named parameters, the task declaration syntax for tasks has been extended slightly. For example, a task that needs a first name and last name might be declared as: task :name, [:first_name, :last_name] The first argument is still the name of the task (:name in this case). The next two arguments are the names of the parameters expected by :name in an array (:first_name and :last_name in the example). To access the values of the parameters, the block defining the task behaviour can now accept a second parameter: task :name, [:first_name, :last_name] do |t, args| puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end The first argument of the block "t" is always bound to the current task object. The second argument "args" is an open-struct like object that allows access to the task arguments. Extra command line arguments to a task are ignored. If you wish to specify default values for the arguments, you can use the with_defaults method in the task body. Here is the above example where we specify default values for the first and last names: task :name, [:first_name, :last_name] do |t, args| args.with_defaults(:first_name => "John", :last_name => "Dough") puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end === Tasks that Expect Parameters and Have Prerequisites Tasks that use parameters have a slightly different format for prerequisites. Use the arrow notation to indicate the prerequisites for tasks with arguments. For example: task :name, [:first_name, :last_name] => [:pre_name] do |t, args| args.with_defaults(:first_name => "John", :last_name => "Dough") puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end === Tasks that take Variable-length Parameters Tasks that need to handle a list of values as a parameter can use the extras method of the args variable. This allows for tasks that can loop over a variable number of values, and its compatible with named parameters as well: task :email, [:message] do |t, args| mail = Mail.new(args.message) recipients = args.extras recipients.each do |target| mail.send_to(target) end end There is also the convenience method to_a that returns all parameters in the sequential order they were given, including those associated with named parameters. === Deprecated Task Parameters Format There is an older format for declaring task parameters that omitted the task argument array and used the :needs keyword to introduce the dependencies. That format is still supported for compatibility, but is not recommended for use. The older format may be dropped in future versions of rake. == Accessing Task Programmatically Sometimes it is useful to manipulate tasks programmatically in a Rakefile. To find a task object use Rake::Task.[]. === Programmatic Task Example For example, the following Rakefile defines two tasks. The :doit task simply prints a simple "DONE" message. The :dont class will lookup the doit class and remove (clear) all of its prerequisites and actions. task :doit do puts "DONE" end task :dont do Rake::Task[:doit].clear end Running this example: $ rake doit (in /Users/jim/working/git/rake/x) DONE $ rake dont doit (in /Users/jim/working/git/rake/x) $ The ability to programmatically manipulate tasks gives rake very powerful meta-programming capabilities w.r.t. task execution, but should be used with caution. == Rules When a file is named as a prerequisite, but does not have a file task defined for it, Rake will attempt to synthesize a task by looking at a list of rules supplied in the Rakefile. Suppose we were trying to invoke task "mycode.o", but no task is defined for it. But the rakefile has a rule that look like this ... rule '.o' => ['.c'] do |t| sh "cc #{t.source} -c -o #{t.name}" end This rule will synthesize any task that ends in ".o". It has a prerequisite a source file with an extension of ".c" must exist. If Rake is able to find a file named "mycode.c", it will automatically create a task that builds "mycode.o" from "mycode.c". If the file "mycode.c" does not exist, rake will attempt to recursively synthesize a rule for it. When a task is synthesized from a rule, the +source+ attribute of the task is set to the matching source file. This allows us to write rules with actions that reference the source file. === Advanced Rules Any regular expression may be used as the rule pattern. Additionally, a proc may be used to calculate the name of the source file. This allows for complex patterns and sources. The following rule is equivalent to the example above. rule( /\.o$/ => [ proc {|task_name| task_name.sub(/\.[^.]+$/, '.c') } ]) do |t| sh "cc #{t.source} -c -o #{t.name}" end *NOTE:* Because of a _quirk_ in Ruby syntax, parenthesis are required on *rule* when the first argument is a regular expression. The following rule might be used for Java files ... rule '.class' => [ proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') } ] do |t| java_compile(t.source, t.name) end *NOTE:* +java_compile+ is a hypothetical method that invokes the java compiler. == Importing Dependencies Any ruby file (including other rakefiles) can be included with a standard Ruby +require+ command. The rules and declarations in the required file are just added to the definitions already accumulated. Because the files are loaded _before_ the rake targets are evaluated, the loaded files must be "ready to go" when the rake command is invoked. This makes generated dependency files difficult to use. By the time rake gets around to updating the dependencies file, it is too late to load it. The +import+ command addresses this by specifying a file to be loaded _after_ the main rakefile is loaded, but _before_ any targets on the command line are invoked. In addition, if the file name matches an explicit task, that task is invoked before loading the file. This allows dependency files to be generated and used in a single rake command invocation. Example: require 'rake/loaders/makefile' file ".depends.mf" => [SRC_LIST] do |t| sh "makedepend -f- -- #{CFLAGS} -- #{t.prerequisites} > #{t.name}" end import ".depends.mf" If ".depends" does not exist, or is out of date w.r.t. the source files, a new ".depends" file is generated using +makedepend+ before loading. == Comments Standard Ruby comments (beginning with "#") can be used anywhere it is legal in Ruby source code, including comments for tasks and rules. However, if you wish a task to be described using the "-T" switch, then you need to use the +desc+ command to describe the task. Example: desc "Create a distribution package" task package: %w[ ... ] do ... end The "-T" switch (or "--tasks" if you like to spell things out) will display a list of tasks that have a description. If you use +desc+ to describe your major tasks, you have a semi-automatic way of generating a summary of your Rake file. $ rake -T (in /home/.../rake) rake clean # Remove any temporary products. rake clobber # Remove any generated file. rake clobber_rdoc # Remove rdoc products rake contrib_test # Run tests for contrib_test rake default # Default Task rake install # Install the application rake lines # Count lines in the main rake file rake rdoc # Build the rdoc HTML Files rake rerdoc # Force a rebuild of the RDOC files rake test # Run tests rake testall # Run all test targets Only tasks with descriptions will be displayed with the "-T" switch. Use "-P" (or "--prereqs") to get a list of all tasks and their prerequisites. == Namespaces As projects grow (and along with it, the number of tasks), it is common for task names to begin to clash. For example, if you might have a main program and a set of sample programs built by a single Rakefile. By placing the tasks related to the main program in one namespace, and the tasks for building the sample programs in a different namespace, the task names will not interfere with each other. For example: namespace "main" do task :build do # Build the main program end end namespace "samples" do task :build do # Build the sample programs end end task build: %w[main:build samples:build] Referencing a task in a separate namespace can be achieved by prefixing the task name with the namespace and a colon (e.g. "main:build" refers to the :build task in the +main+ namespace). Nested namespaces are supported. Note that the name given in the +task+ command is always the unadorned task name without any namespace prefixes. The +task+ command always defines a task in the current namespace. === FileTasks File task names are not scoped by the namespace command. Since the name of a file task is the name of an actual file in the file system, it makes little sense to include file task names in name space. Directory tasks (created by the +directory+ command) are a type of file task and are also not affected by namespaces. === Name Resolution When looking up a task name, rake will start with the current namespace and attempt to find the name there. If it fails to find a name in the current namespace, it will search the parent namespaces until a match is found (or an error occurs if there is no match). The "rake" namespace is a special implicit namespace that refers to the toplevel names. If a task name begins with a "^" character, the name resolution will start in the parent namespace. Multiple "^" characters are allowed. Here is an example file with multiple :run tasks and how various names resolve in different locations. task :run namespace "one" do task :run namespace "two" do task :run # :run => "one:two:run" # "two:run" => "one:two:run" # "one:two:run" => "one:two:run" # "one:run" => "one:run" # "^run" => "one:run" # "^^run" => "rake:run" (the top level task) # "rake:run" => "rake:run" (the top level task) end # :run => "one:run" # "two:run" => "one:two:run" # "^run" => "rake:run" end # :run => "rake:run" # "one:run" => "one:run" # "one:two:run" => "one:two:run" == FileLists FileLists are the way Rake manages lists of files. You can treat a FileList as an array of strings for the most part, but FileLists support some additional operations. === Creating a FileList Creating a file list is easy. Just give it the list of file names: fl = FileList['file1.rb', file2.rb'] Or give it a glob pattern: fl = FileList['*.rb'] == Odds and Ends === do/end versus { } Blocks may be specified with either a +do+/+end+ pair, or with curly braces in Ruby. We _strongly_ recommend using +do+/+end+ to specify the actions for tasks and rules. Because the rakefile idiom tends to leave off parentheses on the task/file/rule methods, unusual ambiguities can arise when using curly braces. For example, suppose that the method +object_files+ returns a list of object files in a project. Now we use +object_files+ as the prerequisites in a rule specified with actions in curly braces. # DON'T DO THIS! file "prog" => object_files { # Actions are expected here (but it doesn't work)! } Because curly braces have a higher precedence than +do+/+end+, the block is associated with the +object_files+ method rather than the +file+ method. This is the proper way to specify the task ... # THIS IS FINE file "prog" => object_files do # Actions go here end == Rakefile Path When issuing the +rake+ command in a terminal, Rake will look for a Rakefile in the current directory. If a Rakefile is not found, it will search parent directories until one is found. For example, if a Rakefile resides in the +project/+ directory, moving deeper into the project's directory tree will not have an adverse effect on rake tasks: $ pwd /home/user/project $ cd lib/foo/bar $ pwd /home/user/project/lib/foo/bar $ rake run_pwd /home/user/project As far as rake is concerned, all tasks are run from the directory in which the Rakefile resides. === Multiple Rake Files Not all tasks need to be included in a single Rakefile. Additional rake files (with the file extension "+.rake+") may be placed in +rakelib+ directory located at the top level of a project (i.e. the same directory that contains the main +Rakefile+). Also, rails projects may include additional rake files in the +lib/tasks+ directory. === Clean and Clobber Tasks Through <tt>require 'rake/clean'</tt> Rake provides +clean+ and +clobber+ tasks: +clean+ :: Clean up the project by deleting scratch files and backup files. Add files to the +CLEAN+ FileList to have the +clean+ target handle them. +clobber+ :: Clobber all generated and non-source files in a project. The task depends on +clean+, so all the +CLEAN+ files will be deleted as well as files in the +CLOBBER+ FileList. The intent of this task is to return a project to its pristine, just unpacked state. You can add file names or glob patterns to both the +CLEAN+ and +CLOBBER+ lists. === Phony Task The phony task can be used as a dependency to allow file-based tasks to use non-file-based-tasks as prerequisites without forcing them to rebuild. You can <tt>require 'rake/phony'</tt> to add the +phony+ task. ---- == See * README.rdoc -- Main documentation for Rake. gems/gems/rake-13.0.3/doc/example/main.c 0000644 00000000147 15102661023 0013362 0 ustar 00 #include <stdio.h> extern void a(); extern void b(); int main () { a(); b(); return 0; } gems/gems/rake-13.0.3/doc/example/Rakefile1 0000644 00000001236 15102661023 0014020 0 ustar 00 # Example Rakefile -*- ruby -*- task :default => [:main] file "a.o" => ["a.c"] do |t| src = t.name.sub(/\.o$/, '.c') sh "gcc #{src} -c -o #{t.name}" end file "b.o" => ["b.c"] do |t| src = t.name.sub(/\.o$/, '.c') sh "gcc #{src} -c -o #{t.name}" end file "main.o" => ["main.c"] do |t| src = t.name.sub(/\.o$/, '.c') sh "gcc #{src} -c -o #{t.name}" end OBJFILES = ["a.o", "b.o", "main.o"] task :obj => OBJFILES file "main" => OBJFILES do |t| sh "gcc -o #{t.name} main.o a.o b.o" end task :clean do rm_f FileList['*.o'] Dir['*~'].each { |fn| rm_f fn } end task :clobber => [:clean] do rm_f "main" end task :run => ["main"] do sh "./main" end gems/gems/rake-13.0.3/doc/example/b.c 0000644 00000000101 15102661023 0012645 0 ustar 00 #include <stdio.h> void b() { printf ("In function b\n"); } gems/gems/rake-13.0.3/doc/example/Rakefile2 0000644 00000001127 15102661023 0014020 0 ustar 00 # Example Rakefile -*- ruby -*- # Using the power of Ruby task :default => [:main] def ext(fn, newext) fn.sub(/\.[^.]+$/, newext) end SRCFILES = Dir['*.c'] OBJFILES = SRCFILES.collect { |fn| ext(fn,".o") } OBJFILES.each do |objfile| srcfile = ext(objfile, ".c") file objfile => [srcfile] do |t| sh "gcc #{srcfile} -c -o #{t.name}" end end file "main" => OBJFILES do |t| sh "gcc -o #{t.name} main.o a.o b.o" end task :clean do rm_f FileList['*.o'] Dir['*~'].each { |fn| rm_f fn } end task :clobber => [:clean] do rm_f "main" end task :run => ["main"] do sh "./main" end gems/gems/rake-13.0.3/doc/example/a.c 0000644 00000000101 15102661023 0012644 0 ustar 00 #include <stdio.h> void a() { printf ("In function a\n"); } gems/gems/rake-13.0.3/doc/command_line_usage.rdoc 0000644 00000013506 15102661023 0015324 0 ustar 00 = Rake Command Line Usage Rake is invoked from the command line using: % rake [options ...] [VAR=VALUE ...] [targets ...] Options are: [<tt><em>name</em>=<em>value</em></tt>] Set the environment variable <em>name</em> to <em>value</em> during the execution of the <b>rake</b> command. You can access the value by using ENV['<em>name</em>']. [<tt>--all</tt> (-A)] Used in combination with the -T and -D options, will force those options to show all the tasks, even the ones without comments. [<tt>--backtrace</tt>{=_output_} (-n)] Enable a full backtrace (i.e. like --trace, but without the task tracing details). The _output_ parameter is optional, but if specified it controls where the backtrace output is sent. If _output_ is <tt>stdout</tt>, then backtrace output is directed to standard output. If _output_ is <tt>stderr</tt>, or if it is missing, then the backtrace output is sent to standard error. [<tt>--comments</tt>] Used in combination with the -W options to force the output to contain commented options only. This is the reverse of <tt>--all</tt>. [<tt>--describe</tt> _pattern_ (-D)] Describe the tasks (matching optional PATTERN), then exit. [<tt>--dry-run</tt> (-n)] Do a dry run. Print the tasks invoked and executed, but do not actually execute any of the actions. [<tt>--execute</tt> _code_ (-e)] Execute some Ruby code and exit. [<tt>--execute-print</tt> _code_ (-p)] Execute some Ruby code, print the result, and exit. [<tt>--execute-continue</tt> _code_ (-E)] Execute some Ruby code, then continue with normal task processing. [<tt>--help</tt> (-H)] Display some help text and exit. [<tt>--jobs</tt> _number_ (-j)] Specifies the maximum number of concurrent threads allowed. Rake will allocate threads as needed up to this maximum number. If omitted, Rake will attempt to estimate the number of CPUs on the system and add 4 to that number. The concurrent threads are used to execute the <tt>multitask</tt> prerequisites. Also see the <tt>-m</tt> option which turns all tasks into multitasks. Sample values: (no -j) : Allow up to (# of CPUs + 4) number of threads --jobs : Allow unlimited number of threads --jobs=1 : Allow only one thread (the main thread) --jobs=16 : Allow up to 16 concurrent threads [<tt>--job-stats</tt> _level_] Display job statistics at the completion of the run. By default, this will display the requested number of active threads (from the -j options) and the maximum number of threads in play at any given time. If the optional _level_ is <tt>history</tt>, then a complete trace of task history will be displayed on standard output. [<tt>--libdir</tt> _directory_ (-I)] Add _directory_ to the list of directories searched for require. [<tt>--multitask</tt> (-m)] Treat all tasks as multitasks. ('make/drake' semantics) [<tt>--nosearch</tt> (-N)] Do not search for a Rakefile in parent directories. [<tt>--prereqs</tt> (-P)] Display a list of all tasks and their immediate prerequisites. [<tt>--quiet</tt> (-q)] Do not echo commands from FileUtils. [<tt>--rakefile</tt> _filename_ (-f)] Use _filename_ as the name of the rakefile. The default rakefile names are +rakefile+ and +Rakefile+ (with +rakefile+ taking precedence). If the rakefile is not found in the current directory, +rake+ will search parent directories for a match. The directory where the Rakefile is found will become the current directory for the actions executed in the Rakefile. [<tt>--rakelibdir</tt> _rakelibdir_ (-R)] Auto-import any .rake files in RAKELIBDIR. (default is 'rakelib') [<tt>--require</tt> _name_ (-r)] Require _name_ before executing the Rakefile. [<tt>--rules</tt>] Trace the rules resolution. [<tt>--silent (-s)</tt>] Like --quiet, but also suppresses the 'in directory' announcement. [<tt>--suppress-backtrace _pattern_ </tt>] Line matching the regular expression _pattern_ will be removed from the backtrace output. Note that the --backtrace option is the full backtrace without these lines suppressed. [<tt>--system</tt> (-g)] Use the system wide (global) rakefiles. The project Rakefile is ignored. By default, the system wide rakefiles are used only if no project Rakefile is found. On Unix-like system, the system wide rake files are located in $HOME/.rake. On a windows system they are stored in $APPDATA/Rake. [<tt>--no-system</tt> (-G)] Use the project level Rakefile, ignoring the system-wide (global) rakefiles. [<tt>--tasks</tt> <em>pattern</em> (-T)] Display a list of the major tasks and their comments. Comments are defined using the "desc" command. If a pattern is given, then only tasks matching the pattern are displayed. [<tt>--trace</tt>{=_output_} (-t)] Turn on invoke/execute tracing. Also enable full backtrace on errors. The _output_ parameter is optional, but if specified it controls where the trace output is sent. If _output_ is <tt>stdout</tt>, then trace output is directed to standard output. If _output_ is <tt>stderr</tt>, or if it is missing, then trace output is sent to standard error. [<tt>--verbose</tt> (-v)] Echo the Sys commands to standard output. [<tt>--version</tt> (-V)] Display the program version and exit. [<tt>--where</tt> <em>pattern</em> (-W)] Display tasks that match <em>pattern</em> and the file and line number where the task is defined. By default this option will display all tasks, not just the tasks that have descriptions. [<tt>--no-deprecation-warnings</tt> (-X)] Do not display the deprecation warnings. In addition, any command line option of the form <em>VAR</em>=<em>VALUE</em> will be added to the environment hash <tt>ENV</tt> and may be tested in the Rakefile. gems/gems/rake-13.0.3/CONTRIBUTING.rdoc 0000644 00000002267 15102661023 0012657 0 ustar 00 = Source Repository Rake is currently hosted at github.

Tasks and dependencies are specified in standard Ruby syntax. Rake has the following features: * Rakefiles (rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?) * Users can specify tasks with prerequisites. * Rake supports rule patterns to synthesize implicit tasks. * Flexible FileLists that act like arrays but know about manipulating file names and paths. * A library of prepackaged tasks to make building rakefiles easier. For example, tasks for building tarballs. (Formerly tasks for building RDoc, Gems, and publishing to FTP were included in rake but they're now available in RDoc, RubyGems, and rake-contrib respectively.) * Supports parallel execution of tasks. == Installation === Gem Installation Download and install rake with the following. gem install rake == Usage === Simple Example First, you must write a "Rakefile" file which contains the build rules. Here's a simple example: task default: %w[test] task :test do ruby "test/unittest.rb" end This Rakefile has two tasks: * A task named "test", which -- upon invocation -- will run a unit test file in Ruby. * A task named "default". This task does nothing by itself, but it has exactly one dependency, namely the "test" task. Invoking the "default" task will cause Rake to invoke the "test" task as well. Running the "rake" command without any options will cause it to run the "default" task in the Rakefile: % ls Rakefile test/ % rake (in /home/some_user/Projects/rake) ruby test/unittest.rb ....unit test output here... Type "rake --help" for all available options. == Resources === Rake Information * {Rake command-line}[link:doc/command_line_usage.rdoc] * {Writing Rakefiles}[link:doc/rakefile.rdoc] * The original {Rake announcement}[link:doc/rational.rdoc] * Rake {glossary}[link:doc/glossary.rdoc] === Presentations and Articles about Rake * Avdi Grimm's rake series: 1. {Rake Basics}[https://avdi.codes/rake-part-1-basics/] 2. {Rake File Lists}[https://avdi.codes/rake-part-2-file-lists-2/] 3. {Rake Rules}[https://avdi.codes/rake-part-3-rules/] 4. {Rake Pathmap}[https://avdi.codes/rake-part-4-pathmap/] 5. {File Operations}[https://avdi.codes/rake-part-5-file-operations/] 6. {Clean and Clobber}[https://avdi.codes/rake-part-6-clean-and-clobber/] 7. {MultiTask}[https://avdi.codes/rake-part-7-multitask/] * {Jim Weirich's 2003 RubyConf presentation}[https://web.archive.org/web/20140221123354/http://onestepback.org/articles/buildingwithrake/] * Martin Fowler's article on Rake: https://martinfowler.com/articles/rake.html == Other Make Re-envisionings ...

Over the past several years I've been asked that question at conferences, panels and over twitter. Due to historical reasons (or maybe just plain laziness) Rake has (incorrectly) been treating the second digit of the version as the major release number. So in my head Rake was already at version 9. Well, it's time to fix things. This next version of Rake drops old, crufty, backwards compatibility hacks such as top level constants, DSL methods defined in Object and numerous other features that are just no longer desired. It's also time to drop the leading zero from the version number as well and call this new version of rake what it really is: Version 10. So, welcome to Rake 10.0! Rake 10 is actually feature identical to the latest version of Rake 9 (that would be the version spelled 0.9.3), *except* that Rake 10 drops all the sundry deprecated features that have accumulated over the years. If your Rakefile is up to date and current with all the new features of Rake 10, you are ready to go. If your Rakefile still uses a few deprecated feeatures, feel free to use Rake 9 (0.9.3) with the same feature set. Just be aware that future features will be in Rake 10 family line. ==== Changes As mentioned above, there are no new features in Rake 10. However, there are a number of features missing: * Classic namespaces are now gone. Rake is no longer able to reflect the options settings in the global variables ($rakefile, $show\_tasks, $show\_prereqs, $trace, $dryrun and $silent). The <tt>--classic-namespace</tt> option is no longer supported. * Global constants are no longer supported. This includes <tt>Task</tt>, <tt>FileTask</tt>, <tt>FileCreationTask</tt> and <tt>RakeApp</tt>). The constant missing hook to warn about using global rake constants has been removed. * The Rake DSL methods (task, file, directory, etc) are in their own module (Rake::DSL). The stub versions of these methods (that printed warnings) in Object have been removed. However, the DSL methods are added to the top-level <tt>main</tt> object. Since <tt>main</tt> is not in the inheritance tree, the presence of the DSL methods in main should be low impact on other libraries. If you want to use the Rake DSL commands from your own code, just include <tt>Rake::DSL</tt> into your own classes and modules. * The deprecated syntax for task arguments (the one using <tt>:needs</tt>) has been removed. * The <tt>--reduce-compat</tt> flag has been removed (it's not needed anymore). * The deprecated <tt>rake/sys.rb</tt> library has been removed. * The deprecated <tt>rake/rdoctask.rb</tt> library has been removed. RDoc supplies its own rake task now. * The deprecated <tt>rake/gempackagetask.rb</tt> library has been removed. Gem supplies its own package task now. There is one small behavioral change: * Non-file tasks now always report the current time as their time stamp. This is different from the previous behavior where non-file tasks reported current time only if there were no prerequisites, and the max prerequisite timestamp otherwise. This lead to inconsistent and surprising behavior when adding prerequisites to tasks that in turn were prequisites to file tasks. The new behavior is more consistent and predictable. ==== Changes (from 0.9.3, 0.9.4, 0.9.5) Since Rake 10 includes the changes from the last version of Rake 9, we'll repeat the changes for versions 0.9.3 through 0.9.5 here. ===== New Features (in 0.9.3) * Multitask tasks now use a thread pool. Use -j to limit the number of available threads. * Use -m to turn regular tasks into multitasks (use at your own risk). * You can now do "Rake.add_rakelib 'dir'" in your Rakefile to programatically add rake task libraries. * You can specific backtrace suppression patterns (see --suppress-backtrace) * Directory tasks can now take prerequisites and actions * Use --backtrace to request a full backtrace without the task trace. * You can say "--backtrace=stdout" and "--trace=stdout" to route trace output to standard output rather than standard error. * Optional 'phony' target (enable with 'require 'rake/phony'") for special purpose builds. * Task#clear now clears task comments as well as actions and prerequisites. Task#clear_comment will specifically target comments. * The --all option will force -T and -D to consider all the tasks, with and without descriptions. ===== Bug Fixes (in 0.9.3) * Semi-colons in windows rakefile paths now work. * Improved Control-C support when invoking multiple test suites. * egrep method now reads files in text mode (better support for Windows) * Better deprecation line number reporting. * The -W option now works with all tasks, whether they have a description or not. * File globs in rake should not be sorted alphabetically, independent of file system and platform. * Numerous internal improvements. * Documentation typos and fixes. ===== Bug Fixes (in 0.9.4) * Exit status with failing tests is not correctly set to non-zero. * Simplified syntax for phony task (for older versions of RDoc). * Stand alone FileList usage gets glob function (without loading in extra dependencies) ===== Bug Fixes (in 0.9.5) * --trace and --backtrace no longer swallow following task names. ==== Thanks As usual, it was input from users that drove a lot of these changes.

This next version of Rake drops old, crufty, backwards compatibility hacks such as top level constants, DSL methods defined in Object and numerous other features that are just no longer desired. It's also time to drop the leading zero from the version number as well and call this new version of rake what it really is: Version 10. So, welcome to Rake 10.0! Rake 10 is actually feature identical to the latest version of Rake 9 (that would be the version spelled 0.9.3), *except* that Rake 10 drops all the sundry deprecated features that have accumulated over the years. If your Rakefile is up to date and current with all the new features of Rake 10, you are ready to go. If your Rakefile still uses a few deprecated feeatures, feel free to use Rake 9 (0.9.3) with the same feature set. Just be aware that future features will be in Rake 10 family line. ==== Changes in 10.0 As mentioned above, there are no new features in Rake 10. However, there are a number of features missing: * Classic namespaces are now gone. Rake is no longer able to reflect the options settings in the global variables ($rakefile, $show\_tasks, $show\_prereqs, $trace, $dryrun and $silent). The <tt>--classic-namespace</tt> option is no longer supported. * Global constants are no longer supported. This includes <tt>Task</tt>, <tt>FileTask</tt>, <tt>FileCreationTask</tt> and <tt>RakeApp</tt>). The constant missing hook to warn about using global rake constants has been removed. * The Rake DSL methods (task, file, directory, etc) are in their own module (Rake::DSL). The stub versions of these methods (that printed warnings) in Object have been removed. However, the DSL methods are added to the top-level <tt>main</tt> object. Since <tt>main</tt> is not in the inheritance tree, the presence of the DSL methods in main should be low impact on other libraries. If you want to use the Rake DSL commands from your own code, just include <tt>Rake::DSL</tt> into your own classes and modules. * The deprecated syntax for task arguments (the one using <tt>:needs</tt>) has been removed. * The <tt>--reduce-compat</tt> flag has been removed (it's not needed anymore). * The deprecated <tt>rake/sys.rb</tt> library has been removed. * The deprecated <tt>rake/rdoctask.rb</tt> library has been removed. RDoc supplies its own rake task now. * The deprecated <tt>rake/gempackagetask.rb</tt> library has been removed. Gem supplies its own package task now. There is one small behavioral change: * Non-file tasks now always report the current time as their time stamp. This is different from the previous behavior where non-file tasks reported current time only if there were no prerequisites, and the max prerequisite timestamp otherwise. This lead to inconsistent and surprising behavior when adding prerequisites to tasks that in turn were prequisites to file tasks. The new behavior is more consistent and predictable. ==== Changes (from 0.9.3) Since Rake 10 includes the changes from the last version of Rake 9, we'll repeat the changes for version 0.9.3 here. ===== New Features * Multitask tasks now use a thread pool. Use -j to limit the number of available threads. * Use -m to turn regular tasks into multitasks (use at your own risk). * You can now do "Rake.add_rakelib 'dir'" in your Rakefile to programatically add rake task libraries. * You can specific backtrace suppression patterns (see --suppress-backtrace) * Directory tasks can now take prerequisites and actions * Use --backtrace to request a full backtrace without the task trace. * You can say "--backtrace=stdout" and "--trace=stdout" to route trace output to standard output rather than standard error. * Optional 'phony' target (enable with 'require 'rake/phony'") for special purpose builds. * Task#clear now clears task comments as well as actions and prerequisites. Task#clear_comment will specifically target comments. * The --all option will force -T and -D to consider all the tasks, with and without descriptions. ===== Bug Fixes * Semi-colons in windows rakefile paths now work. * Improved Control-C support when invoking multiple test suites. * egrep method now reads files in text mode (better support for Windows) * Better deprecation line number reporting. * The -W option now works with all tasks, whether they have a description or not. * File globs in rake should not be sorted alphabetically, independent of file system and platform. * Numerous internal improvements. * Documentation typos and fixes. ==== Thanks As usual, it was input from users that drove a lot of these changes.

Additionally, the internals have be slightly restructured and improved. ==== Changes ===== New Features / Enhancements / Bug Fixes in Version 0.9.0 * Rake now warns when the deprecated :needs syntax used (and suggests the proper syntax in the warning). * Moved Rake DSL commands to top level ruby object 'main'. Rake DSL commands are no longer private methods in Object. (Suggested by James M. Lawrence/quix) * Rake now uses case-insensitive comparisons to find the Rakefile on Windows. Based on patch by Roger Pack. * Rake now requires (instead of loads) files in the test task. Patch by Cezary Baginski. * Fixed typos. Patches by Sean Scot August Moon and R.T. Lechow. * Rake now prints the Rakefile directory only when it's different from the current directory. Patch by Alex Chaffee. * Improved rakefile_location discovery on Windows. Patch by James Tucker. * Rake now recognizes "Windows Server" as a windows system. Patch by Matthias Lüdtke * Rake::RDocTask is deprecated. Use RDoc::Task from RDoc 2.4.2+ (require 'rdoc/task') * Rake::GemPackageTask is deprecated. Use Gem::PackageTask (require 'rubygems/package\_task') * Rake now outputs various messages to $stderr instead of $stdout. * Rake no longer emits warnings for Config. Patch by Santiago Pastorino. * Removed Rake's DSL methods from the top level scope. If you need to call 'task :xzy' in your code, include Rake::DSL into your class, or put the code in a Rake::DSL.environment do ... end block. * Split rake.rb into individual files. * Support for the --where (-W) flag for showing where a task is defined. * Fixed quoting in test task. (http://onestepback.org/redmine/issues/show/44, http://www.pivotaltracker.com/story/show/1223138) * Fixed the silent option parsing problem. (http://onestepback.org/redmine/issues/show/47) * Fixed :verbose=>false flag on sh and ruby commands. * Rake command line options may be given by default in a RAKEOPT environment variable. * Errors in Rake will now display the task invocation chain in effect at the time of the error. * Accepted change by warnickr to not expand test patterns in shell (allowing more files in the test suite). * Fixed that file tasks did not perform prereq lookups in scope (Redmine #57). ==== Thanks As usual, it was input from users that drove a alot of these changes.

The "sh" command now has the same semantics on Windows that it has on Unix based platforms. Rake version 0.8.6 includes minor fixes the the RDoc generation. Rake version 0.8.7 includes a minor fix for JRuby running on windows. ==== Changes ===== New Features / Enhancements in Version 0.8.5 * Improved implementation of the Rake system command for Windows. (patch from James M. Lawrence/quix) * Support for Ruby 1.9's improved system command. (patch from James M. Lawrence/quix) * Rake now includes the configured extension when invoking an executable (Config::CONFIG['EXEEXT]) ===== Bug Fixes in Version 0.8.5 * Environment variable keys are now correctly cased (it matters in some implementations). ==== Thanks As usual, it was input from users that drove a alot of these changes.

NOTE: The version of Rake that comes with Ruby 1.9 has diverged slightly from the core Rake code base. Rake 0.8.4 will work with Ruby 1.9, but is not a strict upgrade for the Rake that comes with Ruby 1.9. A (near) future release of Rake will unify those two codebases. ==== Letter Writing Campaign Thanks to Aaron Patterson (@tenderlove) and Eric Hodel (@drbrain) for their encouraging support in organizing a letter writing campaign to lobby for the "Warning Free" release of rake 0.8.4. A special callout goes to Jonathan D. Lord, Sr (Dr. Wingnut) whose postcard was the first to actually reach me. (see http://tenderlovemaking.com/2009/02/26/we-need-a-new-version-of-rake/ for details) ==== Changes ===== New Features / Enhancements in Version 0.8.4 * Case is preserved on rakefile names. (patch from James M. Lawrence/quix) * Improved Rakefile case insensitivity testing (patch from Luis Lavena). * Windows system dir search order is now: HOME, HOMEDRIVE + HOMEPATH, APPDATA, USERPROFILE (patch from Luis Lavena) * MingGW is now recognized as a windows platform. (patch from Luis Lavena) ===== Bug Fixes in Version 0.8.4 * Removed reference to manage_gem to fix the warning produced by the gem package task. * Fixed stray ARGV option problem that was interfering with Test::Unit::Runner. (patch from Pivotal Labs) ===== Infrastructure Improvements in Version 0.8.4 * Numerous fixes to the windows test suite (patch from Luis Lavena). * Improved Rakefile case insensitivity testing (patch from Luis Lavena). * Better support for windows paths in the test task (patch from Simon Chiang/bahuvrihi) ==== Thanks As usual, it was input from users that drove a alot of these changes.

We now check HOMEDRIVE/HOMEPATH and USERPROFILE if APPDATA isn't found. (Patch supplied by James Tucker). Rake no long aborts if it can't find the directory. * Added fix to handle ruby installations in directories with spaces in their name. ==== Thanks As usual, it was input from users that drove a alot of these changes.

Salter * Adam Majer * Emanuel Indermühle * Ittay Dror * Bheeshmar Redheendran (for spending an afternoon with me debugging windows issues) -- Jim Weirich === 0.8.2 Rake version 0.8.2 is a new release of rake that includes a number of new features and numerous bug fixes. ==== Changes ===== New Features in Version 0.8.2 * Switched from getoptlong to optparse (patches supplied by Edwin Pratomo). * The -T option will now attempt to dynamically sense the size of the terminal. The -T output will only self-truncate if the output is a tty. However, if RAKE_COLUMNS is explicitly set, it will be honored in any case. (Patch provided by Gavin Stark). * The following public methods have been added to rake task objects: * task.clear -- Clear both the prerequisites and actions of the target rake task. * task.clear_prerequisites -- Clear all the existing prerequisites from the target rake task. * task.clear_actions -- Clear all the existing actions from the target rake task. * task.reenable -- Re-enable a task, allowing its actions to be executed again if the task is invoked. * Changed RDoc test task to have no default template. This makes it easier for the tempate to pick up the template from the environment. * Default values for task arguments can easily be specified with the :with_defaults method. (Idea for default argument merging supplied by (Adam Q. Salter) ===== Bug Fixes in Version 0.8.2 * Fixed bug in package task so that it will include the subdir directory in the package for testing. (Bug found by Adam Majer) * Fixed filename dependency order bug in test\_inspect\_pending and test\_to\_s\_pending. (Bug found by Adam Majer) * Fixed check for file utils options to make them immune to the symbol/string differences. (Patch supplied by Edwin Pratomo) * Fixed bug with rules involving multiple source, where only the first dependency of a rule has any effect (Patch supplied by Emanuel Indermühle) * FileList#clone and FileList#dup have better sematics w.r.t. taint and freeze. * Changed from using Mutex to Monitor. Evidently Mutex causes thread join errors when Ruby is compiled with -disable-pthreads. (Patch supplied by Ittay Dror) * Fixed bug in makefile parser that had problems with extra spaces in file task names. (Patch supplied by Ittay Dror) ==== Other changes in Version 0.8.2 * Added ENV var to rake's own Rakefile to prevent OS X from including extended attribute junk in the rake package tar file. (Bug found by Adam Majer) * Added a performance patch for reading large makefile dependency files. (Patch supplied by Ittay Dror) ==== Task Argument Examples Prior to version 0.8.0, rake was only able to handle command line arguments of the form NAME=VALUE that were passed into Rake via the ENV hash. Many folks had asked for some kind of simple command line arguments, perhaps using "--" to separate regular task names from argument values on the command line. The problem is that there was no easy way to associate positional arguments on the command line with different tasks. Suppose both tasks :a and :b expect a command line argument: does the first value go with :a? What if :b is run first? Should it then get the first command line argument. Rake 0.8.0 solves this problem by explicitly passing values directly to the tasks that need them. For example, if I had a release task that required a version number, I could say: rake release[0.8.2] And the string "0.8.2" will be passed to the :release task. Multiple arguments can be passed by separating them with a comma, for example: rake name[john,doe] Just a few words of caution. The rake task name and its arguments need to be a single command line argument to rake. This generally means no spaces. If spaces are needed, then the entire rake + argument string should be quoted. Something like this: rake "name[billy bob, smith]" (Quoting rules vary between operating systems and shells, so make sure you consult the proper docs for your OS/shell). ===== Tasks that Expect Parameters Parameters are only given to tasks that are setup to expect them. In order to handle named parameters, the task declaration syntax for tasks has been extended slightly. For example, a task that needs a first name and last name might be declared as: task :name, :first_name, :last_name The first argument is still the name of the task (:name in this case). The next to argumements are the names of the parameters expected by :name (:first_name and :last_name in the example). To access the values of the parameters, the block defining the task behaviour can now accept a second parameter: task :name, :first_name, :last_name do |t, args| puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end The first argument of the block "t" is always bound to the current task object. The second argument "args" is an open-struct like object that allows access to the task arguments. Extra command line arguments to a task are ignored. Missing command line arguments are given the nil value. ==== Thanks As usual, it was input from users that drove a alot of these changes.

See the examples below for more details. * Comments are limited to 80 columns on output, but full comments can be seen by using the -D parameter. (feature suggested by Jamis Buck). * Explicit exit(n) calls will now set the exit status to n. (patch provided by Stephen Touset). * Rake is now compatible with Ruby 1.9.

Thanks to ... -- Jim Weirich === 0.7.2 Version 0.7.2 supplies a bug fix and a few minor enhancements. In particular, the new version fixes an incompatibility with the soon to be released Ruby 1.8.6. We strongly recommend upgrading to Rake 0.7.2 in order to be compatible with the new version of Ruby. ==== Changes ===== Bug Fixes in 0.7.2 There are quite a number of bug fixes in the new 0.7.2 version of Rake: * Removed dependency on internal fu_xxx functions from FileUtils. * Error messages are now send to stderr rather than stdout (from Payton Quackenbush). * Better error handling on invalid command line arguments (from Payton Quackenbush). * Fixed some bugs where the application object was going to the global appliation instead of using its own data. * Fixed the method name leak from FileUtils (bug found by Glenn Vanderburg). * Added test for noop, bad_option and verbose flags to sh command. * Added a description to the gem task in GemPackageTask. * Fixed a bug when rules have multiple prerequisites (patch by Joel VanderWerf) * Added the handful of RakeFileUtils to the private method as well. ===== New Features in 0.7.2 The following new features are available in Rake version 0.7.2: * Added square and curly bracket patterns to FileList#include (Tilman Sauerbeck). * FileLists can now pass a block to FileList#exclude to exclude files based on calculated values. * Added plain filename support to rule dependents (suggested by Nobu Nakada). * Added pathmap support to rule dependents. In other words, if a pathmap format (beginning with a '%') is given as a Rake rule dependent, then the name of the depend will be the name of the target with the pathmap format applied. * Added a 'tasks' method to a namespace to get a list of tasks associated with the namespace. * Added tar_command and zip_command options to the Package task. * The clean task will no longer delete 'core' if it is a directory. ===== Internal Rake Improvements The following changes will are mainly internal improvements and refactorings and have little effect on the end user. But they may be of interest to the general public. * Added rcov task and updated unit testing for better code coverage. * Added a 'shame' task to the Rakefile. * Added rake_extension to handle detection of extension collisions. * Added a protected 'require "rubygems"' to test/test_application to unbreak cruisecontrol.rb. * Removed rake\_dup. Now we just simply rescue a bad dup. * Refactored the FileList reject logic to remove duplication. * Removed if \_\_FILE\_\_ at the end of the rake.rb file. ==== Thanks As usual, it was input from users that drove a alot of these changes.

Thanks to ... * Payton Quackenbush -- For several error handling improvements. * Glenn Vanderburg -- For finding and fixing the method name leak from FileUtils. * Joel VanderWerf -- for finding and fixing a bug in the handling of multiple prerequisites. * Tilman Sauerbeck -- For some enhancing FileList to support more advanced file globbing. * Nobu Nakada -- For suggesting plain file name support to rule dependents. -- Jim Weirich === 0.7.1 Version 0.7.1 supplies a bug fix and a few minor enhancements. ==== Changes ===== Bug Fixes in 0.7.1 * Changes in the exception reported for the FileUtils.ln caused safe_ln to fail with a NotImplementedError. Rake 0.7.1 will now catch that error or any StandardError and properly fall back to using +cp+. ===== New Features in 0.7.1 * You can filter the results of the --task option by supplying an optional regular expression. This allows the user to easily find a particular task name in a long list of possible names. * Transforming procs in a rule may now return a list of prerequisites. This allows more flexible rule formation. * FileList and String now support a +pathmap+ melthod that makes the transforming paths a bit easier. See the API docs for +pathmap+ for details. * The -f option without a value will disable the search for a Rakefile. This allows the Rakefile to be defined entirely in a library (and loaded with the -r option). The current working directory is not changed when this is done. ==== Thanks As usual, it was input from users that drove a alot of these changes. The following people either contributed patches, made suggestions or made otherwise helpful comments. Thanks to ... * James Britt and Assaph Mehr for reporting and helping to debug the safe_ln issue. -- Jim Weirich === 0.7.0 These changes for Rake have been brewing for a long time. Here they are, I hope you enjoy them. ==== Changes ===== New Features * Name space support for task names (see below). * Prerequisites can be executed in parallel (see below). * Added safe_ln support for openAFS (via Ludvig Omholt). * RDoc defaults to internal (in-process) invocation. The old behavior is still available by setting the +external+ flag to true. * Rakefiles are now loaded with the expanded path to prevent accidental pollution from the Ruby load path. * Task objects my now be used in prerequisite lists directly. * Task objects (in addition to task names) may now be included in the prerequisite list of a task. * Internals cleanup and refactoring. ===== Bug Fixes * Compatibility fixes for Ruby 1.8.4 FileUtils changes. ===== Namespaces Tasks can now be nested inside their own namespaces. Tasks within one namespace will not accidentally interfer with tasks named in a different namespace. For example: namespace "main" do task :build do # Build the main program end end namespace "samples" do task :build do # Build the sample programs end end task :build_all => ["main:build", "samples:build"] Even though both tasks are named :build, they are separate tasks in their own namespaces. The :build_all task (defined in the toplevel namespace) references both build tasks in its prerequisites. You may invoke each of the individual build tasks with the following commands: rake main:build rake samples:build Or invoke both via the :build_all command: rake build_all Namespaces may be nested arbitrarily. Since the name of file tasks correspond to the name of a file in the external file system, FileTasks are not affected by the namespaces. See the Rakefile format documentation (in the Rake API documents) for more information. ===== Parallel Tasks Sometimes you have several tasks that can be executed in parallel. By specifying these tasks as prerequisites to a +multitask+ task. In the following example the tasks copy\_src, copy\_doc and copy\_bin will all execute in parallel in their own thread. multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do puts "All Copies Complete" end ==== Thanks As usual, it was input from users that drove a alot of these changes. The following people either contributed patches, made suggestions or made otherwise helpful comments. Thanks to ... * Doug Young (inspiration for the parallel task) * David Heinemeier Hansson (for --trace message enhancement and for pushing for namespace support). * Ludvig Omholt (for the openAFS fix) -- Jim Weirich === 0.6.1 * Rebuilt 0.6.0 gem without signing. === 0.6.0 Its time for some long requested enhancements and lots of bug fixes ... And a whole new web page. ==== New Web Page The primary documentation for rake has moved from the RubyForge based wiki to its own Hieraki based web site. Constant spam on the wiki made it a difficult to keep clean. The new site will be easier to update and organize. Check out the new documentation at: http://docs.rubyrake.org We will be adding new documentation to the site as time goes on. In addition to the new docs page, make sure you check out Martin Fowlers article on rake at http://martinfowler.com/articles/rake.html ==== Changes ===== New Features * Multiple prerequisites on Rake rules now allowed. However, keep the following in mind: 1. All the prerequisites of a rule must be available before a rule is triggered, where "enabled" means (a) an existing file, (b) a defined rule, or (c) another rule which also must be trigger-able. 2. Rules are checked in order of definition, so it is important to order your rules properly. If a file can be created by two different rules, put the more specific rule first (otherwise the more general rule will trigger first and the specific one will never be triggered). 3. The <tt>source</tt> method now returns the name of the first prerequisite listed in the rule. <tt>sources</tt> returns the names of all the rule prerequisites, ordered as they are defined in the rule. If the task has other prerequisites not defined in the rule (but defined in an explicit task definition), then they will _not_ be included in the sources list. * FileLists may now use the egrep command. This popular enhancement is now a core part of the FileList object. If you want to get a list of all your to-dos, fixmes and TBD comments, add the following to your Rakefile. desc "Look for TODO and FIXME tags in the code" task :todo do FileList['**/*.rb'].egrep /#.*(FIXME|TODO|TBD)/ end * The <tt>investigation</tt> method was added to task object to dump out some important values. This makes it a bit easier to debug Rake tasks. For example, if you are having problems with a particular task, just print it out: task :huh do puts Rake::Task['huh'].investigation end * The Rake::TestTask class now supports a "ruby\_opts" option to pass arbitrary ruby options to a test subprocess. ===== Some Incompatibilities * When using the <tt>ruby</tt> command to start a Ruby subprocess, the Ruby interpreter that is currently running rake is used by default. This makes it easier to use rake in an environment with multiple ruby installation. (Previously, the first ruby command found in the PATH was used). If you wish to chose a different Ruby interpreter, you can explicitly choose the interpreter via the <tt>sh</tt> command. * The major rake classes (Task, FileTask, FileCreationTask, RakeApp) have been moved out of the toplevel scope and are now accessible as Rake::Task, Rake::FileTask, Rake::FileCreationTask and Rake::Application. If your Rakefile directly references any one of these tasks, you may: 1. Update your Rakefile to use the new classnames 2. Use the --classic-namespace option on the rake command to get the old behavior, 3. Add <code>require 'rake/classic_namespace'</code> to the Rakefile to get the old behavior. <tt>rake</tt> will print a rather annoying warning whenever a deprecated class name is referenced without enabling classic namespace. ===== Bug Fixes * Several unit tests and functional tests were fixed to run better under windows. * Directory tasks are now a specialized version of a File task. A directory task will only be triggered if it doesn't exist. It will not be triggered if it is out of date w.r.t. any of its prerequisites. * Fixed a bug in the Rake::GemPackageTask class so that the gem now properly contains the platform name. * Fixed a bug where a prerequisite on a <tt>file</tt> task would cause an exception if the prerequisite did not exist. ==== Thanks As usual, it was input from users that drove a alot of these changes. The following people either contributed patches, made suggestions or made otherwise helpful comments. Thanks to ... * Greg Fast (better ruby_opt test options) * Kelly Felkins (requested by better namespace support) * Martin Fowler (suggested Task.investigation) * Stuart Jansen (send initial patch for multiple prerequisites). * Masao Mutch (better support for non-ruby Gem platforms) * Philipp Neubeck (patch for file task exception fix) -- Jim Weirich === 0.5.4 Time for some minor bug fixes and small enhancements ==== Changes Here are the changes for version 0.5.4 ... * Added double quotes to the test runner. This allows the location of the tests (and runner) to be in a directory path that contains spaces (e.g. "C:/Program Files/ruby/bin"). * Added .svn to default ignore list. Now subversion project metadata is automatically ignored by Rake's FileList. * Updated FileList#include to support nested arrays and filelists. FileLists are flat lists of file names. Using a FileList in an include will flatten out the nested file names. == Thanks As usual, it was input from users that drove a alot of these changes. Thanks to ... * Tilman Sauerbeck for the nested FileList suggestion. * Josh Knowles for pointing out the spaces in directory name problem. -- Jim Weirich === 0.5.3 Although it has only been two weeks since the last release, we have enough updates to the Rake program to make it time for another release. ==== Changes Here are the changes for version 0.5.3 ... * FileLists have been extensively changed so that they mimic the behavior of real arrays even more closely. In particular, operations on FileLists that return a new collection (e.g. collect, reject) will now return a FileList rather than an array. In addition, several places where FileLists were not properly expanded before use have been fixed. * A method (+ext+) to simplify the handling of file extensions was added to String and to Array. * The 'testrb' script in test/unit tends to silently swallow syntax errors in test suites. Because of that, the default test loader is now a rake-provided script. You can still use 'testrb' by setting the loader flag in the test task to :testrb. (See the API documents for TestTask for all the loader flag values). * FileUtil methods (e.g. cp, mv, install) are now declared to be private. This will cut down on the interference with user defined methods of the same name. * Fixed the verbose flag in the TestTask so that the test code is controlled by the flag. Also shortened up some failure messages. (Thanks to Tobias Luetke for the suggestion). * Rules will now properly detect a task that can generate a source file. Previously rules would only consider source files that were already present. * Added an +import+ command that allows Rake to dynamically import dependendencies into a running Rake session. The +import+ command can run tasks to update the dependency file before loading them. Dependency files can be in rake or make format, allowing rake to work with tools designed to generate dependencies for make. ==== Thanks As usual, it was input from users that drove a alot of these changes. Thanks to ... * Brian Gernhardt for the rules fix (especially for the patience to explain the problem to me until I got what he was talking about). * Stefan Lang for pointing out problems in the dark corners of the FileList implementation. * Alexey Verkhovsky pointing out the silently swallows syntax errors in tests. * Tobias Luetke for beautifying the test task output. * Sam Roberts for some of the ideas behind dependency loading. -- Jim Weirich === 0.5.0 It has been a long time in coming, but we finally have a new version of Rake available. ==== Changes * Fixed documentation that was lacking the Rake module name (Tilman Sauerbeck). * Added tar.gz and tar.bz2 support to package task (Tilman Sauerbeck). * Recursive rules are now supported (Tilman Sauerbeck). * Added warning option for the Test Task (requested by Eric Hodel). * The jamis rdoc template is only used if it exists. * Added fix for Ruby 1.8.2 test/unit and rails problem. * Added contributed rake man file (Jani Monoses). * Added Brian Candler's fix for problems in --trace and --dry-run mode. ==== Thanks Lots of people provided input to this release. Thanks to Tilman Sauerbeck for numerous patches, documentation fixes and suggestions. And for also pushing me to get this release out. Also, thanks to Brian Candler for the finding and fixing --trace/dry-run fix. That was an obscure bug. Also to Eric Hodel for some good suggestions. -- Jim Weirich === 0.4.15 ==== Changes Version 0.4.15 is a bug fix update for the Ruby 1.8.2 compatibility changes. This release includes: * Fixed a bug that prevented the TESTOPTS flag from working with the revised for 1.8.2 test task. * Updated the docs on --trace to indicate that it also enables a full backtrace on errors. * Several fixes for new warnings generated. ==== Mini-Roadmap I will continue to issue Rake updates in the 0.4.xx series as new Ruby-1.8.2 issues become manifest. Once the codebase stabilizes, I will release a 0.5.0 version incorporating all the changes. If you are not using Ruby-1.8.2 and wish to avoid version churn, I recommend staying with a release prior to Rake-0.4.14. === 0.4.14 Version 0.4.14 is a compatibility fix to allow Rake's test task to work under Ruby 1.8.2. A change in the Test::Unit autorun feature prevented Rake from running any tests. This release fixes the problem. Rake 0.4.14 is the recommended release for anyone using Ruby 1.8.2. === 0.4.13 * Fixed the dry-run flag so it is operating again. * Multiple arguments to sh and ruby commands will not be interpreted by the shell (patch provided by Jonathan Paisley). === 0.4.12 * Added --silent (-s) to suppress the (in directory) rake message. === 0.4.11 * Changed the "don't know how to rake" message (finally) * Changes references to a literal "Rakefile" to reference the global variable $rakefile (which contains the actual name of the rakefile). === 0.4.10 * Added block support to the "sh" command, allowing users to take special actions on the result of the system call. E.g. sh "shell_command" do |ok, res| puts "Program returned #{res.exitstatus}" if ! ok end === 0.4.9 * Switched to Jamis Buck's RDoc template. * Removed autorequire from Rake's gem spec. This prevents the Rake libraries from loading while using rails. === 0.4.8 * Added support for .rb versions of Rakefile. * Removed \\\n's from test task. * Fixed Ruby 1.9 compatibility issue with FileList. === 0.4.7 * Fixed problem in FileList that caused Ruby 1.9 to go into infinite recursion. Since to_a was removed from Object, it does not need to added back into the list of methods to rewrite in FileList. (Thanks to Kent Sibilev for pointing this out). === 0.4.6 * Removed test version of ln in FileUtils that prevented safe_ln from using ln. === 0.4.5 * Upgraded comments in TestTask. * FileList to_s and inspect now automatically resolve pending changes. * FileList#exclude properly returns the FileList. === 0.4.4 * Fixed initialization problem with @comment. * Now using multi -r technique in TestTask. Switch Rakefile back to using the built-in test task macros because the rake runtime is no longer needed. * Added 'TEST=filename' and 'TESTOPTS=options' to the Test Task macros. * Allow a +test_files+ attribute in test tasks. This allows more flexibility in specifying test files. === 0.4.3 * Fixed Comment leakage. === 0.4.2 * Added safe_ln that falls back to a copy if a file link is not supported. * Package builder now uses safe\_ln. === 0.4.1 * Task comments are now additive, combined with "/". * Works with (soon to be released) rubygems 0.6.2 (or 0.7.0) === 0.4.0 * FileList now uses deferred loading. The file system is not searched until the first call that needs the file names. * VAR=VALUE options are now accepted on the command line and are treated like environment variables. The values may be tested in a Rakefile by referencing ENV['VAR']. * File.mtime is now used (instead of File.new().mtime). === 0.3.2.x * Removed some hidden dependencies on rubygems. Tests now will test gems only if they are installed. * Removed Sys from some example files. I believe that is that last reference to Sys outside of the contrib area. * Updated all copyright notices to include 2004. === 0.3.2 * GEM Installation now works with the application stub. === 0.3.1 * FileLists now automatically ignore CVS, .bak, ! * GEM Installation now works. === 0.3.0 Promoted 0.2.10. === 0.2.10 General * Added title to Rake's rdocs * Contrib packages are no longer included in the documentation. RDoc Issues * Removed default for the '--main' option * Fixed rendering of the rdoc options * Fixed clean/clobber confusion with rerdoc * 'title' attribute added Package Task Library Issues * Version (or explicit :noversion) is required. * +package_file+ attribute is now writable FileList Issues * Dropped bang version of exclude. Now using ant-like include/exclude semantics. * Enabled the "yield self" idiom in FileList#initialize. === 0.2.9 This version contains numerous changes as the RubyConf.new(2003) presentation was being prepared. The changes include: * The monolithic rubyapp task library is in the process of being dropped in favor of lighter weight task libraries. === 0.2.7 * Added "desc" for task descriptions. * -T will now display tasks with descriptions. * -P will display tasks and prerequisites. * Dropped the Sys module in favor of the 1.8.x FileUtils module. Sys is still supported in the contrib area. === 0.2.6 * Moved to RubyForge === 0.2.5 * Switched to standard ruby app builder. * Added no_match option to file matcher. === 0.2.4 * Fixed indir, which neglected to actually change directories. === 0.2.3 * Added rake module for a help target * Added 'for\_files' to Sys * Added a $rakefile constant * Added test for selecting proper rule with multiple targets. gems/gems/rake-13.0.3/exe/rake 0000755 00000002245 15102661023 0011524 0 ustar 00 #!/opt/alt/ruby30/bin/ruby #-- # Copyright (c) 2003, 2004, 2005, 2006, 2007 Jim Weirich # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to # deal in the Software without restriction, including without limitation the # rights to use, copy, modify, merge, publish, distribute, sublicense, and/or # sell copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

An empty string if there # is no extension. # <tt>%X</tt> :: Everything *but* the file extension. # <tt>%s</tt> :: The alternate file separator if defined, otherwise use # # the standard file separator. # <tt>%%</tt> :: A percent sign. # # The <tt>%d</tt> specifier can also have a numeric prefix (e.g. '%2d'). # If the number is positive, only return (up to) +n+ directories in the # path, starting from the left hand side. If +n+ is negative, return (up # to) +n+ directories from the right hand side of the path. # # Examples: # # 'a/b/c/d/file.txt'.pathmap("%2d") => 'a/b' # 'a/b/c/d/file.txt'.pathmap("%-2d") => 'c/d' # # Also the <tt>%d</tt>, <tt>%p</tt>, <tt>%f</tt>, <tt>%n</tt>, # <tt>%x</tt>, and <tt>%X</tt> operators can take a pattern/replacement # argument to perform simple string substitutions on a particular part of # the path. The pattern and replacement are separated by a comma and are # enclosed by curly braces. The replacement spec comes after the % # character but before the operator letter. (e.g. "%{old,new}d"). # Multiple replacement specs should be separated by semi-colons (e.g. # "%{old,new;src,bin}d"). # # Regular expressions may be used for the pattern, and back refs may be # used in the replacement text. Curly braces, commas and semi-colons are # excluded from both the pattern and replacement text (let's keep parsing # reasonable). # # For example: # # "src/org/onestepback/proj/A.java".pathmap("%{^src,class}X.class") # # returns: # # "class/org/onestepback/proj/A.class" # # If the replacement text is '*', then a block may be provided to perform # some arbitrary calculation for the replacement. # # For example: # # "/path/to/file.TXT".pathmap("%X%{.*,*}x") { |ext| # ext.downcase # } # # Returns: # # "/path/to/file.txt" # # This String extension comes from Rake def pathmap(spec=nil, &block) return self if spec.nil? result = "".dup spec.scan(/%\{[^}]*\}-?\d*[sdpfnxX%]|%-?\d+d|%.|[^%]+/) do |frag| case frag when "%f" result << File.basename(self) when "%n" result << File.basename(self).ext when "%d" result << File.dirname(self) when "%x" result << File.extname(self) when "%X" result << self.ext when "%p" result << self when "%s" result << (File::ALT_SEPARATOR || File::SEPARATOR) when "%-" # do nothing when "%%" result << "%" when /%(-?\d+)d/ result << pathmap_partial($1.to_i) when /^%\{([^}]*)\}(\d*[dpfnxX])/ patterns, operator = $1, $2 result << pathmap("%" + operator).pathmap_replace(patterns, &block) when /^%/ fail ArgumentError, "Unknown pathmap specifier #{frag} in '#{spec}'" else result << frag end end result end end end gems/gems/rake-13.0.3/lib/rake/promise.rb 0000644 00000004437 15102661023 0013573 0 ustar 00 # frozen_string_literal: true module Rake # A Promise object represents a promise to do work (a chore) in the # future.

In addition to wrapping libyaml, Psych also # knows how to serialize and de-serialize most Ruby objects to and from # the YAML format. # # = I NEED TO PARSE OR EMIT YAML RIGHT NOW! # # # Parse some YAML # Psych.load("--- foo") # => "foo" # # # Emit some YAML # Psych.dump("foo") # => "--- foo\n...\n" # { :a => 'b'}.to_yaml # => "---\n:a: b\n" # # Got more time on your hands? Keep on reading! # # == YAML Parsing # # Psych provides a range of interfaces for parsing a YAML document ranging from # low level to high level, depending on your parsing needs. At the lowest # level, is an event based parser. Mid level is access to the raw YAML AST, # and at the highest level is the ability to unmarshal YAML to Ruby objects. # # == YAML Emitting # # Psych provides a range of interfaces ranging from low to high level for # producing YAML documents. Very similar to the YAML parsing interfaces, Psych # provides at the lowest level, an event based system, mid-level is building # a YAML AST, and the highest level is converting a Ruby object straight to # a YAML document. # # == High-level API # # === Parsing # # The high level YAML parser provided by Psych simply takes YAML as input and # returns a Ruby data structure.

- Boolean: +true+, +false+. # - Null: +null+. # - \Array: an ordered list of values, enclosed by square brackets: # ["foo", 1, 1.0, 2.0e2, true, false, null] # # - \Object: a collection of name/value pairs, enclosed by curly braces; #

# All examples here assume that this has been done. # # === Parsing \JSON # # You can parse a \String containing \JSON data using # either of two methods: # - <tt>JSON.parse(source, opts)</tt> # - <tt>JSON.parse!(source, opts)</tt> # # where # - +source+ is a Ruby object. # - +opts+ is a \Hash object containing options # that control both input allowed and output formatting. # # The difference between the two methods # is that JSON.parse! omits some checks # and may not be safe for some +source+ data; # use it only for data from trusted sources. # Use the safer method JSON.parse for less trusted sources. # # ==== Parsing \JSON Arrays # # When +source+ is a \JSON array, JSON.parse by default returns a Ruby \Array: #

# ====== Output Options # # The default formatting options generate the most compact # \JSON data, all on one line and with no whitespace. # # You can use these formatting options to generate # \JSON data in a more open format, using whitespace. # See also JSON.pretty_generate. # # - Option +array_nl+ (\String) specifies a string (usually a newline) # to be inserted after each \JSON array; defaults to the empty \String, <tt>''</tt>. # - Option +object_nl+ (\String) specifies a string (usually a newline) # to be inserted after each \JSON object; defaults to the empty \String, <tt>''</tt>. # - Option +indent+ (\String) specifies the string (usually spaces) to be # used for indentation; defaults to the empty \String, <tt>''</tt>; # defaults to the empty \String, <tt>''</tt>; # has no effect unless options +array_nl+ or +object_nl+ specify newlines. # - Option +space+ (\String) specifies a string (usually a space) to be # inserted after the colon in each \JSON object's pair; # defaults to the empty \String, <tt>''</tt>. # - Option +space_before+ (\String) specifies a string (usually a space) to be # inserted before the colon in each \JSON object's pair; # defaults to the empty \String, <tt>''</tt>. # # In this example, +obj+ is used first to generate the shortest # \JSON data (no whitespace), then again with all formatting options # specified: # # obj = {foo: [:bar, :baz], bat: {bam: 0, bad: 1}} #

you have a new \String, instead of the object you began with: # ruby0 = Range.new(0, 2) # json = JSON.generate(ruby0) # json # => '0..2"' # ruby1 = JSON.parse(json) # ruby1 # => '0..2' # ruby1.class # => String # # You can use \JSON _additions_ to preserve the original object. # The addition is an extension of a ruby class, so that: # - \JSON.generate stores more information in the \JSON string. # - \JSON.parse, called with option +create_additions+, # uses that information to create a proper Ruby object. # # This example shows a \Range being generated into \JSON # and parsed back into Ruby, both without and with # the addition for \Range: # ruby = Range.new(0, 2) # # This passage does not use the addition for Range. # json0 = JSON.generate(ruby) # ruby0 = JSON.parse(json0) # # This passage uses the addition for Range. # require 'json/add/range' # json1 = JSON.generate(ruby) # ruby1 = JSON.parse(json1, create_additions: true) # # Make a nice display. # display = <<EOT # Generated JSON: # Without addition: #{json0} (#{json0.class}) #

You need to add the following code to your CGI scripts: require 'lsapi' while LSAPI.accept != nil <your CGI script> ... end There is no need to change the way that how CGI environment variables are being accessed in your scripts. You can find some examples under examples/ folder. Ruby Script Runner ^^^^^^^^^^^^^^^^^^ If you don't want to change your existing Ruby CGI code, you can use our Ruby script runner under scripts/ folder. You need to configure lsruby_runner.rb as a LSAPI application, then add a script handler for "rb" suffix. Rails dispatcher ^^^^^^^^^^^^^^^^ With Ruby LSAPI, we proudly provide a optimum platform for Rails application deployment. Ruby LSAPI has the following advantages over other solutions. * Easy configuration, deploy a Rails application only take a few clicks with our Rails easy configuration * Fast startup, the expensive Rails framework initialization only takes place once when multiple processes need to be started * Resource efficience, ruby processes can be started on demand, idle process will be stop. To use LSAPI with Ruby on Rails, please check out our toturial http://www.litespeedtech.com/support/wiki/doku.php There are a few environment variables that can be tweaked to tune ruby LSAPI process. * LSAPI_CHILDREN (default: 0) LSAPI_CHILDREN controls the maximum number of children processes can be started by the first ruby process started by web server. When set to <=1, the first ruby process will handle request by itself, without starting any child process. When LSAPI_CHILDREN is >1, the LSAPI application is stared in "Self Managed Mode", which will start children processes based on demand. With Rails easy configuration, LSAPI_CHILDREN is set to the value of "Max Connections" by web server, no need to set it explicitly. Usually, there is no need to set value of LSAPI_CHILDREN over 100 in most server environment. * LSAPI_AVOID_FORK (default: 0) LSAPI_AVOID_FORK specifies the policy of the internal process manager in "Self Managed Mode". When set to 0, the internal process manager will stop and start children process on demand to save system resource. This is preferred in a shared hosting environment. When set to 1, the internal process manager will try to avoid freqently stopping and starting children process. This might be preferred in a dedicate hosting environment. * LSAPI_EXTRA_CHILDREN (default: 1/3 of LSAPI_CHILDREN or 0) LSAPI_EXTRA_CHILDREN controls the maximum number of extra children processes can be started when some or all existing children processes are in malfunctioning state. Total number of children processes will be reduced to LSAPI_CHILDREN level as soon as service is back to normal. When LSAPI_AVOID_FORK is set to 0, the default value is 1/3 of LSAPI_CHIDLREN, When LSAPI_AVOID_FORK is set to 1, the default value is 0. * LSAPI_MAX_REQS (default value: 10000) LSAPI_MAX_REQS specifies the maximum number of requests each child process will handle before it exits automatically. This parameter can help reducing memory usage when there are memory leaks in the application. * LSAPI_MAX_IDLE (default value: 300 seconds) In Self Managed Mode, LSAPI_MAX_IDLE controls how long a idle child process will wait for a new request before exit. This option help releasing system resources taken by idle processes. * LSAPI_MAX_IDLE_CHILDREN (default value: 1/3 of LSAPI_CHILDREN or LSAPI_CHILDREN) In Self Managed Mode, LSAI_MAX_IDLE_CHILDREN controls how many idle children processes are allowed. Excessive idle children processes will be killed by the parent process. When LSAPI_AVOID_FORK is set to 0, the default value is 1/3 of LSAPI_CHIDLREN, When LSAPI_AVOID_FORK is set to 1, the default value is LSAPI_CHILDREN. * LSAPI_MAX_PROCESS_TIME (default value: 300 seconds) In Self Managed Mode, LSAPI_MAX_PROCESS_TIME controls the maximum processing time allowed when processing a request. If a child process can not finish processing of a request in the given time period, it will be killed by the parent process. This option can help getting rid of dead or runaway child process. * LSAPI_PGRP_MAX_IDLE (default value: FOREVER ) In Self Managed Mode, LSAPI_PGRP_MAX_IDLE controls how long the parent process will wait before exiting when there is no child process. This option help releasing system resources taken by an idle parent process. * LSAPI_PPID_NO_CHECK By default a LSAPI application check the existence of its parent process and exits automatically if the parent process died. This is to reduce orphan process when web server is restarted. However, it is desireable to disable this feature, such as when a LSAPI process was started manually from command line. LSAPI_PPID_NO_CHECK should be set when you want to disable the checking of existence of parent process.

Please check the [Upgrade > Guide](UPGRADE-GUIDE.md) for more details about migrating your existing > servers, middlewares and applications. For detailed information on specific > changes, check the [Change Log](CHANGELOG.md). Rack provides a minimal, modular, and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the bridge between web servers, web frameworks, and web application into a single method call. The exact details of this are described in the [Rack Specification], which all Rack applications should conform to. ## Installation Add the rack gem to your application bundle, or follow the instructions provided by a [supported web framework](#supported-web-frameworks): ```bash # Install it generally: $ gem install rack --pre # or, add it to your current application gemfile: $ bundle add rack --version 3.0.0 ``` If you need features from `Rack::Session` or `bin/rackup` please add those gems separately. ```bash $ gem install rack-session rackup ``` ## Usage Create a file called `config.ru` with the following contents: ```ruby run do |env| [200, {}, ["Hello World"]] end ``` Run this using the rackup gem or another [supported web server](#supported-web-servers). ```bash $ gem install rackup $ rackup $ curl http://localhost:9292 Hello World ``` ## Supported web servers Rack is supported by a wide range of servers, including: * [Agoo](https://github.com/ohler55/agoo) * [Falcon](https://github.com/socketry/falcon) **(Rack 3 Compatible)** * [Iodine](https://github.com/boazsegev/iodine) * [NGINX Unit](https://unit.nginx.org/) * [Phusion Passenger](https://www.phusionpassenger.com/) (which is mod_rack for Apache and for nginx) * [Puma](https://puma.io/) * [Thin](https://github.com/macournoyer/thin) * [Unicorn](https://yhbt.net/unicorn/) * [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/) * [Lamby](https://lamby.custominktech.com) (for AWS Lambda) You will need to consult the server documentation to find out what features and limitations they may have. In general, any valid Rack app will run the same on all these servers, without changing anything. ### Rackup Rack provides a separate gem, [rackup](https://github.com/rack/rackup) which is a generic interface for running a Rack application on supported servers, which include `WEBRick`, `Puma`, `Falcon` and others. ## Supported web frameworks These frameworks and many others support the [Rack Specification]: * [Camping](https://github.com/camping/camping) * [Hanami](https://hanamirb.org/) * [Padrino](https://padrinorb.com/) * [Roda](https://github.com/jeremyevans/roda) **(Rack 3 Compatible)** * [Ruby on Rails](https://rubyonrails.org/) * [Sinatra](https://sinatrarb.com/) * [Utopia](https://github.com/socketry/utopia) **(Rack 3 Compatible)** * [WABuR](https://github.com/ohler55/wabur) ### Older (possibly unsupported) web frameworks * [Ramaze](http://ramaze.net/) * [Rum](https://github.com/leahneukirchen/rum) ## Available middleware shipped with Rack Between the server and the framework, Rack can be customized to your applications needs using middleware. Rack itself ships with the following middleware: * `Rack::CommonLogger` for creating Apache-style logfiles. * `Rack::ConditionalGet` for returning [Not Modified](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/304) responses when the response has not changed. * `Rack::Config` for modifying the environment before processing the request. * `Rack::ContentLength` for setting a `content-length` header based on body size. * `Rack::ContentType` for setting a default `content-type` header for responses. * `Rack::Deflater` for compressing responses with gzip. * `Rack::ETag` for setting `etag` header on bodies that can be buffered. * `Rack::Events` for providing easy hooks when a request is received and when the response is sent. * `Rack::Files` for serving static files. * `Rack::Head` for returning an empty body for HEAD requests. * `Rack::Lint` for checking conformance to the [Rack Specification]. * `Rack::Lock` for serializing requests using a mutex. * `Rack::Logger` for setting a logger to handle logging errors. * `Rack::MethodOverride` for modifying the request method based on a submitted parameter. * `Rack::Recursive` for including data from other paths in the application, and for performing internal redirects. * `Rack::Reloader` for reloading files if they have been modified. * `Rack::Runtime` for including a response header with the time taken to process the request. * `Rack::Sendfile` for working with web servers that can use optimized file serving for file system paths. * `Rack::ShowException` for catching unhandled exceptions and presenting them in a nice and helpful way with clickable backtrace. * `Rack::ShowStatus` for using nice error pages for empty client error responses. * `Rack::Static` for more configurable serving of static files. * `Rack::TempfileReaper` for removing temporary files creating during a request. All these components use the same interface, which is described in detail in the [Rack Specification]. These optional components can be used in any way you wish. ### Convenience interfaces If you want to develop outside of existing frameworks, implement your own ones, or develop middleware, Rack provides many helpers to create Rack applications quickly and without doing the same web stuff all over: * `Rack::Request` which also provides query string parsing and multipart handling. * `Rack::Response` for convenient generation of HTTP replies and cookie handling. * `Rack::MockRequest` and `Rack::MockResponse` for efficient and quick testing of Rack application without real HTTP round-trips. * `Rack::Cascade` for trying additional Rack applications if an application returns a not found or method not supported response. * `Rack::Directory` for serving files under a given directory, with directory indexes. * `Rack::MediaType` for parsing content-type headers. * `Rack::Mime` for determining content-type based on file extension. * `Rack::RewindableInput` for making any IO object rewindable, using a temporary file buffer. * `Rack::URLMap` to route to multiple applications inside the same process. ## Configuration Rack exposes several configuration parameters to control various features of the implementation. ### `param_depth_limit` ```ruby Rack::Utils.param_depth_limit = 32 # default ``` The maximum amount of nesting allowed in parameters. For example, if set to 3, this query string would be allowed: ``` ?a[b][c]=d ``` but this query string would not be allowed: ``` ?a[b][c][d]=e ``` Limiting the depth prevents a possible stack overflow when parsing parameters. ### `multipart_file_limit` ```ruby Rack::Utils.multipart_file_limit = 128 # default ``` The maximum number of parts with a filename a request can contain. Accepting too many parts can lead to the server running out of file handles. The default is 128, which means that a single request can't upload more than 128 files at once. Set to 0 for no limit. Can also be set via the `RACK_MULTIPART_FILE_LIMIT` environment variable. (This is also aliased as `multipart_part_limit` and `RACK_MULTIPART_PART_LIMIT` for compatibility) ### `multipart_total_part_limit` The maximum total number of parts a request can contain of any type, including both file and non-file form fields. The default is 4096, which means that a single request can't contain more than 4096 parts. Set to 0 for no limit. Can also be set via the `RACK_MULTIPART_TOTAL_PART_LIMIT` environment variable. ## Changelog See [CHANGELOG.md](CHANGELOG.md). ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) for specific details about how to make a contribution to Rack.

It takes exactly one argument, the *environment* and returns a non-frozen Array of exactly three values: The *status*, the *headers*, and the *body*. == The Environment The environment must be an unfrozen instance of Hash that includes CGI-like headers. The Rack application is free to modify the environment. The environment is required to include these variables (adopted from {PEP 333}[https://peps.python.org/pep-0333/]), except when they'd be empty, but see below. <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as "GET" or "POST". This cannot ever be an empty string, and so is always required. <tt>SCRIPT_NAME</tt>:: The initial portion of the request URL's "path" that corresponds to the application object, so that the application knows its virtual "location". This may be an empty string, if the application corresponds to the "root" of the server. <tt>PATH_INFO</tt>:: The remainder of the request URL's "path", designating the virtual "location" of the request's target within the application. This may be an empty string, if the request URL targets the application root and does not have a trailing slash. This value may be percent-encoded when originating from a URL. <tt>QUERY_STRING</tt>:: The portion of the request URL that follows the <tt>?</tt>, if any. May be empty, but is always required! <tt>SERVER_NAME</tt>:: When combined with <tt>SCRIPT_NAME</tt> and <tt>PATH_INFO</tt>, these variables can be used to complete the URL. Note, however, that <tt>HTTP_HOST</tt>, if present, should be used in preference to <tt>SERVER_NAME</tt> for reconstructing the request URL. <tt>SERVER_NAME</tt> can never be an empty string, and so is always required. <tt>SERVER_PORT</tt>:: An optional +Integer+ which is the port the server is running on. Should be specified if the server is running on a non-standard port. <tt>SERVER_PROTOCOL</tt>:: A string representing the HTTP version used for the request. <tt>HTTP_</tt> Variables:: Variables corresponding to the client-supplied HTTP request headers (i.e., variables whose names begin with <tt>HTTP_</tt>). The presence or absence of these variables should correspond with the presence or absence of the appropriate HTTP header in the request. See {RFC3875 section 4.1.18}[https://tools.ietf.org/html/rfc3875#section-4.1.18] for specific behavior. In addition to this, the Rack environment must include these Rack-specific variables: <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the request URL. <tt>rack.input</tt>:: See below, the input stream. <tt>rack.errors</tt>:: See below, the error stream. <tt>rack.hijack?</tt>:: See below, if present and true, indicates that the server supports partial hijacking. <tt>rack.hijack</tt>:: See below, if present, an object responding to +call+ that is used to perform a full hijack. Additional environment specifications have approved to standardized middleware APIs. None of these are required to be implemented by the server. <tt>rack.session</tt>:: A hash-like interface for storing request session data. The store must implement: store(key, value) (aliased as []=); fetch(key, default = nil) (aliased as []); delete(key); clear; to_hash (returning unfrozen Hash instance); <tt>rack.logger</tt>:: A common object interface for logging messages. The object must implement: info(message, &block) debug(message, &block) warn(message, &block) error(message, &block) fatal(message, &block) <tt>rack.multipart.buffer_size</tt>:: An Integer hint to the multipart parser as to what chunk size to use for reads and writes. <tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind. This factory will be used to instantiate the tempfile for each multipart form file upload field, rather than the default class of Tempfile. The server or the application can store their own data in the environment, too. The keys must contain at least one dot, and should be prefixed uniquely. The prefix <tt>rack.</tt> is reserved for use with the Rack core distribution and other accepted specifications and must not be used otherwise. The <tt>SERVER_PORT</tt> must be an Integer if set. The <tt>SERVER_NAME</tt> must be a valid authority as defined by RFC7540. The <tt>HTTP_HOST</tt> must be a valid authority as defined by RFC7540. The <tt>SERVER_PROTOCOL</tt> must match the regexp <tt>HTTP/\d(\.\d)?</tt>. If the <tt>HTTP_VERSION</tt> is present, it must equal the <tt>SERVER_PROTOCOL</tt>. The environment must not contain the keys <tt>HTTP_CONTENT_TYPE</tt> or <tt>HTTP_CONTENT_LENGTH</tt> (use the versions without <tt>HTTP_</tt>). The CGI keys (named without a period) must have String values. If the string values for CGI keys contain non-ASCII characters, they should use ASCII-8BIT encoding. There are the following restrictions: * <tt>rack.url_scheme</tt> must either be +http+ or +https+. * There must be a valid input stream in <tt>rack.input</tt>. * There must be a valid error stream in <tt>rack.errors</tt>. * There may be a valid hijack callback in <tt>rack.hijack</tt> * The <tt>REQUEST_METHOD</tt> must be a valid token. * The <tt>SCRIPT_NAME</tt>, if non-empty, must start with <tt>/</tt> * The <tt>PATH_INFO</tt>, if non-empty, must start with <tt>/</tt> * The <tt>CONTENT_LENGTH</tt>, if given, must consist of digits only. * One of <tt>SCRIPT_NAME</tt> or <tt>PATH_INFO</tt> must be set. <tt>PATH_INFO</tt> should be <tt>/</tt> if <tt>SCRIPT_NAME</tt> is empty. <tt>SCRIPT_NAME</tt> never should be <tt>/</tt>, but instead be empty. <tt>rack.response_finished</tt>:: An array of callables run by the server after the response has been processed. This would typically be invoked after sending the response to the client, but it could also be invoked if an error occurs while generating the response or sending the response; in that case, the error argument will be a subclass of +Exception+. The callables are invoked with +env, status, headers, error+ arguments and should not raise any exceptions. They should be invoked in reverse order of registration. === The Input Stream The input stream is an IO-like object which contains the raw HTTP POST data. When applicable, its external encoding must be "ASCII-8BIT" and it must be opened in binary mode, for Ruby 1.9 compatibility. The input stream must respond to +gets+, +each+, and +read+. * +gets+ must be called without arguments and return a string, or +nil+ on EOF. * +read+ behaves like IO#read. Its signature is <tt>read([length, [buffer]])</tt>. If given, +length+ must be a non-negative Integer (>= 0) or +nil+, and +buffer+ must be a String and may not be nil. If +length+ is given and not nil, then this method reads at most +length+ bytes from the input stream. If +length+ is not given or nil, then this method reads all data until EOF. When EOF is reached, this method returns nil if +length+ is given and not nil, or "" if +length+ is not given or is nil. If +buffer+ is given, then the read data will be placed into +buffer+ instead of a newly created String object. * +each+ must be called without arguments and only yield Strings. * +close+ can be called on the input stream to indicate that the any remaining input is not needed. === The Error Stream The error stream must respond to +puts+, +write+ and +flush+. * +puts+ must be called with a single argument that responds to +to_s+. * +write+ must be called with a single argument that is a String. * +flush+ must be called without arguments and must be called in order to make the error appear for sure. * +close+ must never be called on the error stream. === Hijacking The hijacking interfaces provides a means for an application to take control of the HTTP connection. There are two distinct hijack interfaces: full hijacking where the application takes over the raw connection, and partial hijacking where the application takes over just the response body stream. In both cases, the application is responsible for closing the hijacked stream. Full hijacking only works with HTTP/1. Partial hijacking is functionally equivalent to streaming bodies, and is still optionally supported for backwards compatibility with older Rack versions. ==== Full Hijack Full hijack is used to completely take over an HTTP/1 connection. It occurs before any headers are written and causes the request to ignores any response generated by the application. It is intended to be used when applications need access to raw HTTP/1 connection. If +rack.hijack+ is present in +env+, it must respond to +call+ and return an +IO+ instance which can be used to read and write to the underlying connection using HTTP/1 semantics and formatting. ==== Partial Hijack Partial hijack is used for bi-directional streaming of the request and response body. It occurs after the status and headers are written by the server and causes the server to ignore the Body of the response. It is intended to be used when applications need bi-directional streaming. If +rack.hijack?+ is present in +env+ and truthy, an application may set the special response header +rack.hijack+ to an object that responds to +call+, accepting a +stream+ argument. After the response status and headers have been sent, this hijack callback will be invoked with a +stream+ argument which follows the same interface as outlined in "Streaming Body". Servers must ignore the +body+ part of the response tuple when the +rack.hijack+ response header is present. Using an empty +Array+ instance is recommended. The special response header +rack.hijack+ must only be set if the request +env+ has a truthy +rack.hijack?+. == The Response === The Status This is an HTTP status. It must be an Integer greater than or equal to 100. === The Headers The headers must be a unfrozen Hash. The header keys must be Strings. Special headers starting "rack." are for communicating with the server, and must not be sent back to the client. The header must not contain a +Status+ key. Header keys must conform to RFC7230 token specification, i.e. cannot contain non-printable ASCII, DQUOTE or "(),/:;<=>?@[\]{}". Header keys must not contain uppercase ASCII characters (A-Z). Header values must be either a String instance, or an Array of String instances, such that each String instance must not contain characters below 037. === The content-type There must not be a <tt>content-type</tt> header key when the +Status+ is 1xx, 204, or 304. === The content-length There must not be a <tt>content-length</tt> header key when the +Status+ is 1xx, 204, or 304. === The Body The Body is typically an +Array+ of +String+ instances, an enumerable that yields +String+ instances, a +Proc+ instance, or a File-like object. The Body must respond to +each+ or +call+. It may optionally respond to +to_path+ or +to_ary+. A Body that responds to +each+ is considered to be an Enumerable Body. A Body that responds to +call+ is considered to be a Streaming Body. A Body that responds to both +each+ and +call+ must be treated as an Enumerable Body, not a Streaming Body. If it responds to +each+, you must call +each+ and not +call+. If the Body doesn't respond to +each+, then you can assume it responds to +call+. The Body must either be consumed or returned. The Body is consumed by optionally calling either +each+ or +call+. Then, if the Body responds to +close+, it must be called to release any resources associated with the generation of the body. In other words, +close+ must always be called at least once; typically after the web server has sent the response to the client, but also in cases where the Rack application makes internal/virtual requests and discards the response. After calling +close+, the Body is considered closed and should not be consumed again. If the original Body is replaced by a new Body, the new Body must also consume the original Body by calling +close+ if possible. If the Body responds to +to_path+, it must return a +String+ path for the local file system whose contents are identical to that produced by calling +each+; this may be used by the server as an alternative, possibly more efficient way to transport the response. The +to_path+ method does not consume the body. ==== Enumerable Body The Enumerable Body must respond to +each+. It must only be called once. It must not be called after being closed. and must only yield String values. The Body itself should not be an instance of String, as this will break in Ruby 1.9. Middleware must not call +each+ directly on the Body. Instead, middleware can return a new Body that calls +each+ on the original Body, yielding at least once per iteration. If the Body responds to +to_ary+, it must return an +Array+ whose contents are identical to that produced by calling +each+. Middleware may call +to_ary+ directly on the Body and return a new Body in its place. In other words, middleware can only process the Body directly if it responds to +to_ary+. If the Body responds to both +to_ary+ and +close+, its implementation of +to_ary+ must call +close+. ==== Streaming Body The Streaming Body must respond to +call+. It must only be called once. It must not be called after being closed. It takes a +stream+ argument. The +stream+ argument must implement: <tt>read, write, <<, flush, close, close_read, close_write, closed?</tt> The semantics of these IO methods must be a best effort match to those of a normal Ruby IO or Socket object, using standard arguments and raising standard exceptions. Servers are encouraged to simply pass on real IO objects, although it is recognized that this approach is not directly compatible with HTTP/2. == Thanks Some parts of this specification are adopted from {PEP 333 – Python Web Server Gateway Interface v1.0}[https://peps.python.org/pep-0333/] I'd like to thank everyone involved in that effort. gems/gems/rack-3.0.8/CONTRIBUTING.md 0000644 00000005452 15102661023 0012251 0 ustar 00 # Contributing to Rack Rack is work of [hundreds of contributors](https://github.com/rack/rack/graphs/contributors).

This cannot ever ## be an empty string, and so is ## always required. ## <tt>SCRIPT_NAME</tt>:: The initial portion of the request ## URL's "path" that corresponds to the ## application object, so that the ## application knows its virtual ## "location". This may be an empty ## string, if the application corresponds ## to the "root" of the server. ## <tt>PATH_INFO</tt>:: The remainder of the request URL's ## "path", designating the virtual ## "location" of the request's target ## within the application. This may be an ## empty string, if the request URL targets ## the application root and does not have a ## trailing slash. This value may be ## percent-encoded when originating from ## a URL. ## <tt>QUERY_STRING</tt>:: The portion of the request URL that ## follows the <tt>?</tt>, if any. May be ## empty, but is always required! ## <tt>SERVER_NAME</tt>:: When combined with <tt>SCRIPT_NAME</tt> and ## <tt>PATH_INFO</tt>, these variables can be ## used to complete the URL. Note, however, ## that <tt>HTTP_HOST</tt>, if present, ## should be used in preference to ## <tt>SERVER_NAME</tt> for reconstructing ## the request URL. ## <tt>SERVER_NAME</tt> can never be an empty ## string, and so is always required. ## <tt>SERVER_PORT</tt>:: An optional +Integer+ which is the port the ## server is running on. Should be specified if ## the server is running on a non-standard port. ## <tt>SERVER_PROTOCOL</tt>:: A string representing the HTTP version used ## for the request. ## <tt>HTTP_</tt> Variables:: Variables corresponding to the ## client-supplied HTTP request ## headers (i.e., variables whose ## names begin with <tt>HTTP_</tt>). The ## presence or absence of these ## variables should correspond with ## the presence or absence of the ## appropriate HTTP header in the ## request. See ## {RFC3875 section 4.1.18}[https://tools.ietf.org/html/rfc3875#section-4.1.18] ## for specific behavior. ## In addition to this, the Rack environment must include these ## Rack-specific variables: ## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the ## request URL. ## <tt>rack.input</tt>:: See below, the input stream. ## <tt>rack.errors</tt>:: See below, the error stream. ## <tt>rack.hijack?</tt>:: See below, if present and true, indicates ## that the server supports partial hijacking. ## <tt>rack.hijack</tt>:: See below, if present, an object responding ## to +call+ that is used to perform a full ## hijack. ## Additional environment specifications have approved to ## standardized middleware APIs. None of these are required to ## be implemented by the server. ## <tt>rack.session</tt>:: A hash-like interface for storing ## request session data. ## The store must implement: if session = env[RACK_SESSION] ## store(key, value) (aliased as []=); unless session.respond_to?(:store) && session.respond_to?(:[]=) raise LintError, "session #{session.inspect} must respond to store and []=" end ## fetch(key, default = nil) (aliased as []); unless session.respond_to?(:fetch) && session.respond_to?(:[]) raise LintError, "session #{session.inspect} must respond to fetch and []" end ## delete(key); unless session.respond_to?(:delete) raise LintError, "session #{session.inspect} must respond to delete" end ## clear; unless session.respond_to?(:clear) raise LintError, "session #{session.inspect} must respond to clear" end ## to_hash (returning unfrozen Hash instance); unless session.respond_to?(:to_hash) && session.to_hash.kind_of?(Hash) && !session.to_hash.frozen? raise LintError, "session #{session.inspect} must respond to to_hash and return unfrozen Hash instance" end end ## <tt>rack.logger</tt>:: A common object interface for logging messages. ## The object must implement: if logger = env[RACK_LOGGER] ## info(message, &block) unless logger.respond_to?(:info) raise LintError, "logger #{logger.inspect} must respond to info" end ## debug(message, &block) unless logger.respond_to?(:debug) raise LintError, "logger #{logger.inspect} must respond to debug" end ## warn(message, &block) unless logger.respond_to?(:warn) raise LintError, "logger #{logger.inspect} must respond to warn" end ## error(message, &block) unless logger.respond_to?(:error) raise LintError, "logger #{logger.inspect} must respond to error" end ## fatal(message, &block) unless logger.respond_to?(:fatal) raise LintError, "logger #{logger.inspect} must respond to fatal" end end ## <tt>rack.multipart.buffer_size</tt>:: An Integer hint to the multipart parser as to what chunk size to use for reads and writes. if bufsize = env[RACK_MULTIPART_BUFFER_SIZE] unless bufsize.is_a?(Integer) && bufsize > 0 raise LintError, "rack.multipart.buffer_size must be an Integer > 0 if specified" end end ## <tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind.

The web server is then responsible for writing the file contents # to the client. This can dramatically reduce the amount of work required # by the Ruby backend and takes advantage of the web server's optimized file # delivery code. # # In order to take advantage of this middleware, the response body must # respond to +to_path+ and the request must include an x-sendfile-type # header. Rack::Files and other components implement +to_path+ so there's # rarely anything you need to do in your application. The x-sendfile-type # header is typically set in your web servers configuration. The following # sections attempt to document # # === Nginx # # Nginx supports the x-accel-redirect header. This is similar to x-sendfile # but requires parts of the filesystem to be mapped into a private URL # hierarchy. # # The following example shows the Nginx configuration required to create # a private "/files/" area, enable x-accel-redirect, and pass the special # x-sendfile-type and x-accel-mapping headers to the backend: # # location ~ /files/(.*) { # internal; # alias /var/www/$1; # } # # location / { # proxy_redirect off; # # proxy_set_header Host $host; # proxy_set_header X-Real-IP $remote_addr; # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # # proxy_set_header x-sendfile-type x-accel-redirect; # proxy_set_header x-accel-mapping /var/www/=/files/; # # proxy_pass http://127.0.0.1:8080/; # } # # Note that the x-sendfile-type header must be set exactly as shown above. # The x-accel-mapping header should specify the location on the file system, # followed by an equals sign (=), followed name of the private URL pattern # that it maps to. The middleware performs a simple substitution on the # resulting path. # # See Also: https://www.nginx.com/resources/wiki/start/topics/examples/xsendfile # # === lighttpd # # Lighttpd has supported some variation of the x-sendfile header for some # time, although only recent version support x-sendfile in a reverse proxy # configuration. # # $HTTP["host"] == "example.com" { # proxy-core.protocol = "http" # proxy-core.balancer = "round-robin" # proxy-core.backends = ( # "127.0.0.1:8000", # "127.0.0.1:8001", # ... # ) # # proxy-core.allow-x-sendfile = "enable" # proxy-core.rewrite-request = ( # "x-sendfile-type" => (".*" => "x-sendfile") # ) # } # # See Also: http://redmine.lighttpd.net/wiki/lighttpd/Docs:ModProxyCore # # === Apache # # x-sendfile is supported under Apache 2.x using a separate module: # # https://tn123.org/mod_xsendfile/ # # Once the module is compiled and installed, you can enable it using # XSendFile config directive: # # RequestHeader Set x-sendfile-type x-sendfile # ProxyPassReverse / http://localhost:8001/ # XSendFile on # # === Mapping parameter # # The third parameter allows for an overriding extension of the # x-accel-mapping header.

([#1993](https://github.com/rack/rack/pull/1993), [@ioquatix]) ## [3.0.1] - 2022-11-18 ### Fixed - `MethodOverride` does not look for an override if a request does not include form/parseable data. - `Rack::Lint::Wrapper` correctly handles `respond_to?` with `to_ary`, `each`, `call` and `to_path`, forwarding to the body. ([#1981](https://github.com/rack/rack/pull/1981), [@ioquatix]) ## [3.0.0] - 2022-09-06 - No changes ## [3.0.0.rc1] - 2022-09-04 ### SPEC Changes - Stream argument must implement `<<` https://github.com/rack/rack/pull/1959 - `close` may be called on `rack.input` https://github.com/rack/rack/pull/1956 - `rack.response_finished` may be used for executing code after the response has been finished https://github.com/rack/rack/pull/1952 ## [3.0.0.beta1] - 2022-08-08 ### Security - Do not use semicolon as GET parameter separator. ([#1733](https://github.com/rack/rack/pull/1733), [@jeremyevans]) ### SPEC Changes - Response array must now be non-frozen. - Response `status` must now be an integer greater than or equal to 100. - Response `headers` must now be an unfrozen hash. - Response header keys can no longer include uppercase characters. - Response header values can be an `Array` to handle multiple values (and no longer supports `\n` encoded headers). - Response body can now respond to `#call` (streaming body) instead of `#each` (enumerable body), for the equivalent of response hijacking in previous versions. - Middleware must no longer call `#each` on the body, but they can call `#to_ary` on the body if it responds to `#to_ary`. - `rack.input` is no longer required to be rewindable. - `rack.multithread`/`rack.multiprocess`/`rack.run_once`/`rack.version` are no longer required environment keys. - `SERVER_PROTOCOL` is now a required environment key, matching the HTTP protocol used in the request. - `rack.hijack?` (partial hijack) and `rack.hijack` (full hijack) are now independently optional. - `rack.hijack_io` has been removed completely. - `rack.response_finished` is an optional environment key which contains an array of callable objects that must accept `#call(env, status, headers, error)` and are invoked after the response is finished (either successfully or unsuccessfully). - It is okay to call `#close` on `rack.input` to indicate that you no longer need or care about the input. - The stream argument supplied to the streaming body and hijack must support `#<<` for writing output. ### Removed - Remove `rack.multithread`/`rack.multiprocess`/`rack.run_once`. These variables generally come too late to be useful. ([#1720](https://github.com/rack/rack/pull/1720), [@ioquatix], [@jeremyevans])) - Remove deprecated Rack::Request::SCHEME_WHITELIST. ([@jeremyevans]) - Remove internal cookie deletion using pattern matching, there are very few practical cases where it would be useful and browsers handle it correctly without us doing anything special.

([#1606](https://github.com/rack/rack/issues/1606), [@pvande](https://github.com/pvande)) - Removed antiquated handlers: FCGI, LSWS, SCGI, Thin. ([#1658](https://github.com/rack/rack/pull/1658), [@ioquatix]) - Removed options from `Rack::Builder.parse_file` and `Rack::Builder.load_file`.

([#1809](https://github.com/rack/rack/issues/1809), [@jeremyevans]) - `Rack::Request.forwarded_authority` (and methods that call it, such as `host`) now returns the last authority in the forwarded header, instead of the first, as earlier forwarded authorities can be forged by clients. This restores the Rack 2.1 behavior. ([#1829](https://github.com/rack/rack/issues/1809), [@jeremyevans]) - Use lower case cookie attributes when creating cookies, and fold cookie attributes to lower case when reading cookies (specifically impacting `secure` and `httponly` attributes). ([#1849](https://github.com/rack/rack/pull/1849), [@ioquatix]) - The response array must now be mutable (non-frozen) so middleware can modify it without allocating a new Array,therefore reducing object allocations.

([@mperham](https://github.com/mperham)) # History/News Archive Items below this line are from the previously maintained HISTORY.md and NEWS.md files. ## [2.0.0.rc1] 2016-05-06 - Rack::Session::Abstract::ID is deprecated. Please change to use Rack::Session::Abstract::Persisted ## [2.0.0.alpha] 2015-12-04 - First-party "SameSite" cookies. Browsers omit SameSite cookies from third-party requests, closing the door on many CSRF attacks. - Pass `same_site: true` (or `:strict`) to enable: response.set_cookie 'foo', value: 'bar', same_site: true or `same_site: :lax` to use Lax enforcement: response.set_cookie 'foo', value: 'bar', same_site: :lax - Based on version 7 of the Same-site Cookies internet draft: https://tools.ietf.org/html/draft-west-first-party-cookies-07 - Thanks to Ben Toews (@mastahyeti) and Bob Long (@bobjflong) for updating to drafts 5 and 7. - Add `Rack::Events` middleware for adding event based middleware: middleware that does not care about the response body, but only cares about doing work at particular points in the request / response lifecycle. - Add `Rack::Request#authority` to calculate the authority under which the response is being made (this will be handy for h2 pushes). - Add `Rack::Response::Helpers#cache_control` and `cache_control=`. Use this for setting cache control headers on your response objects. - Add `Rack::Response::Helpers#etag` and `etag=`. Use this for setting etag values on the response. - Introduce `Rack::Response::Helpers#add_header` to add a value to a multi-valued response header. Implemented in terms of other `Response#*_header` methods, so it's available to any response-like class that includes the `Helpers` module. - Add `Rack::Request#add_header` to match. - `Rack::Session::Abstract::ID` IS DEPRECATED. Please switch to `Rack::Session::Abstract::Persisted`. `Rack::Session::Abstract::Persisted` uses a request object rather than the `env` hash. - Pull `ENV` access inside the request object in to a module. This will help with legacy Request objects that are ENV based but don't want to inherit from Rack::Request - Move most methods on the `Rack::Request` to a module `Rack::Request::Helpers` and use public API to get values from the request object. This enables users to mix `Rack::Request::Helpers` in to their own objects so they can implement `(get|set|fetch|each)_header` as they see fit (for example a proxy object). - Files and directories with + in the name are served correctly. Rather than unescaping paths like a form, we unescape with a URI parser using `Rack::Utils.unescape_path`. Fixes #265 - Tempfiles are automatically closed in the case that there were too many posted. - Added methods for manipulating response headers that don't assume they're stored as a Hash. Response-like classes may include the Rack::Response::Helpers module if they define these methods: - Rack::Response#has_header? - Rack::Response#get_header - Rack::Response#set_header - Rack::Response#delete_header - Introduce Util.get_byte_ranges that will parse the value of the HTTP_RANGE string passed to it without depending on the `env` hash. `byte_ranges` is deprecated in favor of this method. - Change Session internals to use Request objects for looking up session information. This allows us to only allocate one request object when dealing with session objects (rather than doing it every time we need to manipulate cookies, etc). - Add `Rack::Request#initialize_copy` so that the env is duped when the request gets duped. - Added methods for manipulating request specific data. This includes data set as CGI parameters, and just any arbitrary data the user wants to associate with a particular request. New methods: - Rack::Request#has_header? - Rack::Request#get_header - Rack::Request#fetch_header - Rack::Request#each_header - Rack::Request#set_header - Rack::Request#delete_header - lib/rack/utils.rb: add a method for constructing "delete" cookie headers. This allows us to construct cookie headers without depending on the side effects of mutating a hash. - Prevent extremely deep parameters from being parsed.

See [the bundler website](https://bundler.io) for information on getting started, and Gemfile(5) for more information on the `Gemfile` format. ## OPTIONS * `--no-color`: Print all output without color * `--retry`, `-r`: Specify the number of times you wish to attempt network commands * `--verbose`, `-V`: Print out additional logging information ## BUNDLE COMMANDS We divide `bundle` subcommands into primary commands and utilities: ## PRIMARY COMMANDS * [`bundle install(1)`](bundle-install.1.html): Install the gems specified by the `Gemfile` or `Gemfile.lock` * [`bundle update(1)`](bundle-update.1.html): Update dependencies to their latest versions * [`bundle package(1)`](bundle-package.1.html): Package the .gem files required by your application into the `vendor/cache` directory * [`bundle exec(1)`](bundle-exec.1.html): Execute a script in the current bundle * [`bundle config(1)`](bundle-config.1.html): Specify and read configuration options for Bundler * `bundle help(1)`: Display detailed help for each subcommand ## UTILITIES * [`bundle add(1)`](bundle-add.1.html): Add the named gem to the Gemfile and run `bundle install` * [`bundle binstubs(1)`](bundle-binstubs.1.html): Generate binstubs for executables in a gem * [`bundle check(1)`](bundle-check.1.html): Determine whether the requirements for your application are installed and available to Bundler * [`bundle show(1)`](bundle-show.1.html): Show the source location of a particular gem in the bundle * [`bundle outdated(1)`](bundle-outdated.1.html): Show all of the outdated gems in the current bundle * `bundle console(1)`: Start an IRB session in the current bundle * [`bundle open(1)`](bundle-open.1.html): Open an installed gem in the editor * [`bundle lock(1)`](bundle-lock.1.html): Generate a lockfile for your dependencies * [`bundle viz(1)`](bundle-viz.1.html): Generate a visual representation of your dependencies * [`bundle init(1)`](bundle-init.1.html): Generate a simple `Gemfile`, placed in the current directory * [`bundle gem(1)`](bundle-gem.1.html): Create a simple gem, suitable for development with Bundler * [`bundle platform(1)`](bundle-platform.1.html): Display platform compatibility information * [`bundle clean(1)`](bundle-clean.1.html): Clean up unused gems in your Bundler directory * [`bundle doctor(1)`](bundle-doctor.1.html): Display warnings about common problems * [`bundle remove(1)`](bundle-remove.1.html): Removes gems from the Gemfile ## PLUGINS When running a command that isn't listed in PRIMARY COMMANDS or UTILITIES, Bundler will try to find an executable on your path named `bundler-<command>` and execute it, passing down any extra arguments to it. ## OBSOLETE These commands are obsolete and should no longer be used: * `bundle cache(1)` * `bundle show(1)` gems/gems/bundler-2.2.33/lib/bundler/man/bundle-platform.1.ronn 0000644 00000002175 15102661024 0017716 0 ustar 00 bundle-platform(1) -- Displays platform compatibility information ================================================================= ## SYNOPSIS `bundle platform` [--ruby] ## DESCRIPTION `platform` will display information from your Gemfile, Gemfile.lock, and Ruby VM about your platform. For instance, using this Gemfile(5): source "https://rubygems.org" ruby "1.9.3" gem "rack" If you run `bundle platform` on Ruby 1.9.3, it will display the following output: Your platform is: x86_64-linux Your app has gems that work on these platforms: * ruby Your Gemfile specifies a Ruby version requirement: * ruby 1.9.3 Your current platform satisfies the Ruby version requirement. `platform` will list all the platforms in your `Gemfile.lock` as well as the `ruby` directive if applicable from your Gemfile(5). It will also let you know if the `ruby` directive requirement has been met. If `ruby` directive doesn't match the running Ruby VM, it will tell you what part does not. ## OPTIONS * `--ruby`: It will display the ruby directive information, so you don't have to parse it from the Gemfile(5). gems/gems/bundler-2.2.33/lib/bundler/man/bundle-lock.1.ronn 0000644 00000005735 15102661024 0017027 0 ustar 00 bundle-lock(1) -- Creates / Updates a lockfile without installing ================================================================= ## SYNOPSIS `bundle lock` [--update] [--local] [--print] [--lockfile=PATH] [--full-index] [--add-platform] [--remove-platform] [--patch] [--minor] [--major] [--strict] [--conservative] ## DESCRIPTION Lock the gems specified in Gemfile. ## OPTIONS * `--update=<*gems>`: Ignores the existing lockfile. Resolve then updates lockfile. Taking a list of gems or updating all gems if no list is given. * `--local`: Do not attempt to connect to `rubygems.org`. Instead, Bundler will use the gems already present in Rubygems' cache or in `vendor/cache`. Note that if a appropriate platform-specific gem exists on `rubygems.org` it will not be found. * `--print`: Prints the lockfile to STDOUT instead of writing to the file system. * `--lockfile=<path>`: The path where the lockfile should be written to. * `--full-index`: Fall back to using the single-file index of all gems. * `--add-platform`: Add a new platform to the lockfile, re-resolving for the addition of that platform. * `--remove-platform`: Remove a platform from the lockfile. * `--patch`: If updating, prefer updating only to next patch version. * `--minor`: If updating, prefer updating only to next minor version. * `--major`: If updating, prefer updating to next major version (default). * `--strict`: If updating, do not allow any gem to be updated past latest --patch | --minor | --major. * `--conservative`: If updating, use bundle install conservative update behavior and do not allow shared dependencies to be updated. ## UPDATING ALL GEMS If you run `bundle lock` with `--update` option without list of gems, bundler will ignore any previously installed gems and resolve all dependencies again based on the latest versions of all gems available in the sources. ## UPDATING A LIST OF GEMS Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the `Gemfile.lock`. For instance, you only want to update `nokogiri`, run `bundle lock --update nokogiri`. Bundler will update `nokogiri` and any of its dependencies, but leave the rest of the gems that you specified locked to the versions in the `Gemfile.lock`. ## SUPPORTING OTHER PLATFORMS If you want your bundle to support platforms other than the one you're running locally, you can run `bundle lock --add-platform PLATFORM` to add PLATFORM to the lockfile, force bundler to re-resolve and consider the new platform when picking gems, all without needing to have a machine that matches PLATFORM handy to install those platform-specific gems on.

Bundler needs the Gemfile to determine things such as a gem\'s groups, \fBautorequire\fR, and platforms, etc\., and that information isn\'t stored in the lockfile\. The Gemfile and lockfile must be synced in order to \fBbundle exec\fR successfully, so \fBbundle exec\fR updates the lockfile beforehand\. . .SS "Loading" By default, when attempting to \fBbundle exec\fR to a file with a ruby shebang, Bundler will \fBKernel\.load\fR that file instead of using \fBKernel\.exec\fR\. For the vast majority of cases, this is a performance improvement\. In a rare few cases, this could cause some subtle side\-effects (such as dependence on the exact contents of \fB$0\fR or \fB__FILE__\fR) and the optimization can be disabled by enabling the \fBdisable_exec_load\fR setting\. . .SS "Shelling out" Any Ruby code that opens a subshell (like \fBsystem\fR, backticks, or \fB%x{}\fR) will automatically use the current Bundler environment\. If you need to shell out to a Ruby command that is not part of your current bundle, use the \fBwith_clean_env\fR method with a block\. Any subshells created inside the block will be given the environment present before Bundler was activated\.

Any Bundler commands run in a subshell will inherit the current Gemfile, so commands that need to run in the context of a different bundle also need to use \fBwith_clean_env\fR\. . .IP "" 4 . .nf Bundler\.with_clean_env do Dir\.chdir "/other/bundler/project" do `bundle exec \./script` end end . .fi . .IP "" 0 . .P Bundler provides convenience helpers that wrap \fBsystem\fR and \fBexec\fR, and they can be used like this: . .IP "" 4 . .nf Bundler\.clean_system(\'brew install wget\') Bundler\.clean_exec(\'brew install wget\') . .fi . .IP "" 0 . .SH "RUBYGEMS PLUGINS" At present, the Rubygems plugin system requires all files named \fBrubygems_plugin\.rb\fR on the load path of \fIany\fR installed gem when any Ruby code requires \fBrubygems\.rb\fR\. This includes executables installed into the system, like \fBrails\fR, \fBrackup\fR, and \fBrspec\fR\. . .P Since Rubygems plugins can contain arbitrary Ruby code, they commonly end up activating themselves or their dependencies\. . .P For instance, the \fBgemcutter 0\.5\fR gem depended on \fBjson_pure\fR\. If you had that version of gemcutter installed (even if you \fIalso\fR had a newer version without this problem), Rubygems would activate \fBgemcutter 0\.5\fR and \fBjson_pure <latest>\fR\. . .P If your Gemfile(5) also contained \fBjson_pure\fR (or a gem with a dependency on \fBjson_pure\fR), the latest version on your system might conflict with the version in your Gemfile(5), or the snapshot version in your \fBGemfile\.lock\fR\. . .P If this happens, bundler will say: . .IP "" 4 . .nf You have already activated json_pure 1\.4\.6 but your Gemfile requires json_pure 1\.4\.3\.

In general, you should use [bundle install(1)](bundle-install.1.html) to install the same exact gems and versions across machines. You would use `bundle update` to explicitly update the version of a gem. ## OPTIONS * `--all`: Update all gems specified in Gemfile. * `--group=<name>`, `-g=[<name>]`: Only update the gems in the specified group. For instance, you can update all gems in the development group with `bundle update --group development`. You can also call `bundle update rails --group test` to update the rails gem and all gems in the test group, for example. * `--source=<name>`: The name of a `:git` or `:path` source used in the Gemfile(5). For instance, with a `:git` source of `http://github.com/rails/rails.git`, you would call `bundle update --source rails` * `--local`: Do not attempt to fetch gems remotely and use the gem cache instead. * `--ruby`: Update the locked version of Ruby to the current version of Ruby. * `--bundler`: Update the locked version of bundler to the invoked bundler version. * `--full-index`: Fall back to using the single-file index of all gems. * `--jobs=[<number>]`, `-j[<number>]`: Specify the number of jobs to run in parallel. The default is `1`. * `--retry=[<number>]`: Retry failed network or git requests for <number> times. * `--quiet`: Only output warnings and errors. * `--redownload`: Force downloading every gem. * `--patch`: Prefer updating only to next patch version. * `--minor`: Prefer updating only to next minor version. * `--major`: Prefer updating to next major version (default). * `--strict`: Do not allow any gem to be updated past latest `--patch` | `--minor` | `--major`. * `--conservative`: Use bundle install conservative update behavior and do not allow indirect dependencies to be updated. ## UPDATING ALL GEMS If you run `bundle update --all`, bundler will ignore any previously installed gems and resolve all dependencies again based on the latest versions of all gems available in the sources. Consider the following Gemfile(5): source "https://rubygems.org" gem "rails", "3.0.0.rc" gem "nokogiri" When you run [bundle install(1)](bundle-install.1.html) the first time, bundler will resolve all of the dependencies, all the way down, and install what you need: Fetching gem metadata from https://rubygems.org/.........

Use `bundle show [gemname]` to see where a bundled gem is installed. As you can see, even though you have two gems in the Gemfile(5), your application needs 26 different gems in order to run. Bundler remembers the exact versions it installed in `Gemfile.lock`. The next time you run [bundle install(1)](bundle-install.1.html), bundler skips the dependency resolution and installs the same gems as it installed last time. After checking in the `Gemfile.lock` into version control and cloning it on another machine, running [bundle install(1)](bundle-install.1.html) will _still_ install the gems that you installed last time. You don't need to worry that a new release of `erubis` or `mail` changes the gems you use. However, from time to time, you might want to update the gems you are using to the newest versions that still match the gems in your Gemfile(5). To do this, run `bundle update --all`, which will ignore the `Gemfile.lock`, and resolve all the dependencies again. Keep in mind that this process can result in a significantly different set of the 25 gems, based on the requirements of new gems that the gem authors released since the last time you ran `bundle update --all`. ## UPDATING A LIST OF GEMS Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the `Gemfile.lock`. For instance, in the scenario above, imagine that `nokogiri` releases version `1.4.4`, and you want to update it _without_ updating Rails and all of its dependencies. To do this, run `bundle update nokogiri`. Bundler will update `nokogiri` and any of its dependencies, but leave alone Rails and its dependencies. ## OVERLAPPING DEPENDENCIES Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same second-level dependency. For instance, consider the case of `thin` and `rack-perftools-profiler`. source "https://rubygems.org" gem "thin" gem "rack-perftools-profiler" The `thin` gem depends on `rack >= 1.0`, while `rack-perftools-profiler` depends on `rack ~> 1.0`. If you run bundle install, you get: Fetching source index for https://rubygems.org/ Installing daemons (1.1.0) Installing eventmachine (0.12.10) with native extensions Installing open4 (1.0.1) Installing perftools.rb (0.4.7) with native extensions Installing rack (1.2.1) Installing rack-perftools_profiler (0.0.2) Installing thin (1.2.7) with native extensions Using bundler (1.0.0.rc.3) In this case, the two gems have their own set of dependencies, but they share `rack` in common. If you run `bundle update thin`, bundler will update `daemons`, `eventmachine` and `rack`, which are dependencies of `thin`, but not `open4` or `perftools.rb`, which are dependencies of `rack-perftools_profiler`. Note that `bundle update thin` will update `rack` even though it's _also_ a dependency of `rack-perftools_profiler`. In short, by default, when you update a gem using `bundle update`, bundler will update all dependencies of that gem, including those that are also dependencies of another gem. To prevent updating indirect dependencies, prior to version 1.14 the only option was the `CONSERVATIVE UPDATING` behavior in [bundle install(1)](bundle-install.1.html): In this scenario, updating the `thin` version manually in the Gemfile(5), and then running [bundle install(1)](bundle-install.1.html) will only update `daemons` and `eventmachine`, but not `rack`. For more information, see the `CONSERVATIVE UPDATING` section of [bundle install(1)](bundle-install.1.html). Starting with 1.14, specifying the `--conservative` option will also prevent indirect dependencies from being updated. ## PATCH LEVEL OPTIONS Version 1.14 introduced 4 patch-level options that will influence how gem versions are resolved. One of the following options can be used: `--patch`, `--minor` or `--major`. `--strict` can be added to further influence resolution. * `--patch`: Prefer updating only to next patch version. * `--minor`: Prefer updating only to next minor version. * `--major`: Prefer updating to next major version (default). * `--strict`: Do not allow any gem to be updated past latest `--patch` | `--minor` | `--major`. When Bundler is resolving what versions to use to satisfy declared requirements in the Gemfile or in parent gems, it looks up all available versions, filters out any versions that don't satisfy the requirement, and then, by default, sorts them from newest to oldest, considering them in that order. Providing one of the patch level options (e.g. `--patch`) changes the sort order of the satisfying versions, causing Bundler to consider the latest `--patch` or `--minor` version available before other versions. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph. For example, if gem 'foo' is locked at 1.0.2, with no gem requirement defined in the Gemfile, and versions 1.0.3, 1.0.4, 1.1.0, 1.1.1, 2.0.0 all exist, the default order of preference by default (`--major`) will be "2.0.0, 1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2". If the `--patch` option is used, the order of preference will change to "1.0.4, 1.0.3, 1.0.2, 1.1.1, 1.1.0, 2.0.0". If the `--minor` option is used, the order of preference will change to "1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2, 2.0.0". Combining the `--strict` option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far. To continue the previous example, if both `--patch` and `--strict` options are used, the available versions for resolution would be "1.0.4, 1.0.3, 1.0.2". If `--minor` and `--strict` are used, it would be "1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2". Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available. If the gem requirement for `foo` in the Gemfile is '~> 1.0', that will accomplish the same thing as providing the `--minor` and `--strict` options. ## PATCH LEVEL EXAMPLES Given the following gem specifications: foo 1.4.3, requires: ~> bar 2.0 foo 1.4.4, requires: ~> bar 2.0 foo 1.4.5, requires: ~> bar 2.1 foo 1.5.0, requires: ~> bar 2.1 foo 1.5.1, requires: ~> bar 3.0 bar with versions 2.0.3, 2.0.4, 2.1.0, 2.1.1, 3.0.0 Gemfile: gem 'foo' Gemfile.lock: foo (1.4.3) bar (~> 2.0) bar (2.0.3) Cases: # Command Line Result ------------------------------------------------------------ 1 bundle update --patch 'foo 1.4.5', 'bar 2.1.1' 2 bundle update --patch foo 'foo 1.4.5', 'bar 2.1.1' 3 bundle update --minor 'foo 1.5.1', 'bar 3.0.0' 4 bundle update --minor --strict 'foo 1.5.0', 'bar 2.1.1' 5 bundle update --patch --strict 'foo 1.4.4', 'bar 2.0.4' In case 1, bar is upgraded to 2.1.1, a minor version increase, because the dependency from foo 1.4.5 required it. In case 2, only foo is requested to be unlocked, but bar is also allowed to move because it's not a declared dependency in the Gemfile. In case 3, bar goes up a whole major release, because a minor increase is preferred now for foo, and when it goes to 1.5.1, it requires 3.0.0 of bar. In case 4, foo is preferred up to a minor version, but 1.5.1 won't work because the --strict flag removes bar 3.0.0 from consideration since it's a major increment. In case 5, both foo and bar have any minor or major increments removed from consideration because of the --strict flag, so the most they can move is up to 1.4.4 and 2.0.4. ## RECOMMENDED WORKFLOW In general, when working with an application managed with bundler, you should use the following workflow: * After you create your Gemfile(5) for the first time, run $ bundle install * Check the resulting `Gemfile.lock` into version control $ git add Gemfile.lock * When checking out this repository on another development machine, run $ bundle install * When checking out this repository on a deployment machine, run $ bundle install --deployment * After changing the Gemfile(5) to reflect a new or update dependency, run $ bundle install * Make sure to check the updated `Gemfile.lock` into version control $ git add Gemfile.lock * If [bundle install(1)](bundle-install.1.html) reports a conflict, manually update the specific gems that you changed in the Gemfile(5) $ bundle update rails thin * If you want to update all the gems to the latest possible versions that still match the gems listed in the Gemfile(5), run $ bundle update --all gems/gems/bundler-2.2.33/lib/bundler/man/bundle-info.1 0000644 00000000701 15102661024 0016043 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-INFO" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-info\fR \- Show information for the given gem in your bundle . .SH "SYNOPSIS" \fBbundle info\fR [GEM] [\-\-path] . .SH "DESCRIPTION" Print the basic information about the provided GEM such as homepage, version, path and summary\. . .SH "OPTIONS" . .TP \fB\-\-path\fR Print the path of the given gem gems/gems/bundler-2.2.33/lib/bundler/man/bundle-update.1 0000644 00000033073 15102661024 0016402 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-UPDATE" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-update\fR \- Update your gems to the latest available versions . .SH "SYNOPSIS" \fBbundle update\fR \fI*gems\fR [\-\-all] [\-\-group=NAME] [\-\-source=NAME] [\-\-local] [\-\-ruby] [\-\-bundler[=VERSION]] [\-\-full\-index] [\-\-jobs=JOBS] [\-\-quiet] [\-\-patch|\-\-minor|\-\-major] [\-\-redownload] [\-\-strict] [\-\-conservative] . .SH "DESCRIPTION" Update the gems specified (all gems, if \fB\-\-all\fR flag is used), ignoring the previously installed gems specified in the \fBGemfile\.lock\fR\.

One of the following options can be used: \fB\-\-patch\fR, \fB\-\-minor\fR or \fB\-\-major\fR\. \fB\-\-strict\fR can be added to further influence resolution\. . .TP \fB\-\-patch\fR Prefer updating only to next patch version\. . .TP \fB\-\-minor\fR Prefer updating only to next minor version\. . .TP \fB\-\-major\fR Prefer updating to next major version (default)\. . .TP \fB\-\-strict\fR Do not allow any gem to be updated past latest \fB\-\-patch\fR | \fB\-\-minor\fR | \fB\-\-major\fR\. . .P When Bundler is resolving what versions to use to satisfy declared requirements in the Gemfile or in parent gems, it looks up all available versions, filters out any versions that don\'t satisfy the requirement, and then, by default, sorts them from newest to oldest, considering them in that order\. . .P Providing one of the patch level options (e\.g\. \fB\-\-patch\fR) changes the sort order of the satisfying versions, causing Bundler to consider the latest \fB\-\-patch\fR or \fB\-\-minor\fR version available before other versions\. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph\. . .P For example, if gem \'foo\' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\. . .P If the \fB\-\-patch\fR option is used, the order of preference will change to "1\.0\.4, 1\.0\.3, 1\.0\.2, 1\.1\.1, 1\.1\.0, 2\.0\.0"\. . .P If the \fB\-\-minor\fR option is used, the order of preference will change to "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2, 2\.0\.0"\. . .P Combining the \fB\-\-strict\fR option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far\. . .P To continue the previous example, if both \fB\-\-patch\fR and \fB\-\-strict\fR options are used, the available versions for resolution would be "1\.0\.4, 1\.0\.3, 1\.0\.2"\. If \fB\-\-minor\fR and \fB\-\-strict\fR are used, it would be "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\. . .P Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available\. If the gem requirement for \fBfoo\fR in the Gemfile is \'~> 1\.0\', that will accomplish the same thing as providing the \fB\-\-minor\fR and \fB\-\-strict\fR options\. . .SH "PATCH LEVEL EXAMPLES" Given the following gem specifications: . .IP "" 4 . .nf foo 1\.4\.3, requires: ~> bar 2\.0 foo 1\.4\.4, requires: ~> bar 2\.0 foo 1\.4\.5, requires: ~> bar 2\.1 foo 1\.5\.0, requires: ~> bar 2\.1 foo 1\.5\.1, requires: ~> bar 3\.0 bar with versions 2\.0\.3, 2\.0\.4, 2\.1\.0, 2\.1\.1, 3\.0\.0 . .fi . .IP "" 0 . .P Gemfile: . .IP "" 4 . .nf gem \'foo\' . .fi . .IP "" 0 . .P Gemfile\.lock: . .IP "" 4 . .nf foo (1\.4\.3) bar (~> 2\.0) bar (2\.0\.3) . .fi . .IP "" 0 . .P Cases: . .IP "" 4 . .nf # Command Line Result \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1 bundle update \-\-patch \'foo 1\.4\.5\', \'bar 2\.1\.1\' 2 bundle update \-\-patch foo \'foo 1\.4\.5\', \'bar 2\.1\.1\' 3 bundle update \-\-minor \'foo 1\.5\.1\', \'bar 3\.0\.0\' 4 bundle update \-\-minor \-\-strict \'foo 1\.5\.0\', \'bar 2\.1\.1\' 5 bundle update \-\-patch \-\-strict \'foo 1\.4\.4\', \'bar 2\.0\.4\' . .fi . .IP "" 0 . .P In case 1, bar is upgraded to 2\.1\.1, a minor version increase, because the dependency from foo 1\.4\.5 required it\. . .P In case 2, only foo is requested to be unlocked, but bar is also allowed to move because it\'s not a declared dependency in the Gemfile\. . .P In case 3, bar goes up a whole major release, because a minor increase is preferred now for foo, and when it goes to 1\.5\.1, it requires 3\.0\.0 of bar\. . .P In case 4, foo is preferred up to a minor version, but 1\.5\.1 won\'t work because the \-\-strict flag removes bar 3\.0\.0 from consideration since it\'s a major increment\. . .P In case 5, both foo and bar have any minor or major increments removed from consideration because of the \-\-strict flag, so the most they can move is up to 1\.4\.4 and 2\.0\.4\. . .SH "RECOMMENDED WORKFLOW" In general, when working with an application managed with bundler, you should use the following workflow: . .IP "\(bu" 4 After you create your Gemfile(5) for the first time, run . .IP $ bundle install . .IP "\(bu" 4 Check the resulting \fBGemfile\.lock\fR into version control . .IP $ git add Gemfile\.lock . .IP "\(bu" 4 When checking out this repository on another development machine, run . .IP $ bundle install . .IP "\(bu" 4 When checking out this repository on a deployment machine, run . .IP $ bundle install \-\-deployment . .IP "\(bu" 4 After changing the Gemfile(5) to reflect a new or update dependency, run . .IP $ bundle install . .IP "\(bu" 4 Make sure to check the updated \fBGemfile\.lock\fR into version control . .IP $ git add Gemfile\.lock . .IP "\(bu" 4 If bundle install(1) \fIbundle\-install\.1\.html\fR reports a conflict, manually update the specific gems that you changed in the Gemfile(5) . .IP $ bundle update rails thin . .IP "\(bu" 4 If you want to update all the gems to the latest possible versions that still match the gems listed in the Gemfile(5), run . .IP $ bundle update \-\-all . .IP "" 0 gems/gems/bundler-2.2.33/lib/bundler/man/bundle-add.1.ronn 0000644 00000002335 15102661024 0016620 0 ustar 00 bundle-add(1) -- Add gem to the Gemfile and run bundle install ================================================================ ## SYNOPSIS `bundle add` <GEM_NAME> [--group=GROUP] [--version=VERSION] [--source=SOURCE] [--git=GIT] [--branch=BRANCH] [--skip-install] [--strict] [--optimistic] ## DESCRIPTION Adds the named gem to the Gemfile and run `bundle install`. `bundle install` can be avoided by using the flag `--skip-install`.

This command will add the gem to both your [`Gemfile(5)`][Gemfile(5)] and Gemfile.lock if it isn't listed yet. Example: bundle install bundle inject 'rack' '> 0' This will inject the 'rack' gem with a version greater than 0 in your [`Gemfile(5)`][Gemfile(5)] and Gemfile.lock gems/gems/bundler-2.2.33/lib/bundler/man/bundle-exec.1.ronn 0000644 00000013574 15102661024 0017023 0 ustar 00 bundle-exec(1) -- Execute a command in the context of the bundle ================================================================ ## SYNOPSIS `bundle exec` [--keep-file-descriptors] <command> ## DESCRIPTION This command executes the command, making all gems specified in the [`Gemfile(5)`][Gemfile(5)] available to `require` in Ruby programs. Essentially, if you would normally have run something like `rspec spec/my_spec.rb`, and you want to use the gems specified in the [`Gemfile(5)`][Gemfile(5)] and installed via [bundle install(1)](bundle-install.1.html), you should run `bundle exec rspec spec/my_spec.rb`. Note that `bundle exec` does not require that an executable is available on your shell's `$PATH`. ## OPTIONS * `--keep-file-descriptors`: Exec in Ruby 2.0 began discarding non-standard file descriptors. When this flag is passed, exec will revert to the 1.9 behaviour of passing all file descriptors to the new process. ## BUNDLE INSTALL --BINSTUBS If you use the `--binstubs` flag in [bundle install(1)](bundle-install.1.html), Bundler will automatically create a directory (which defaults to `app_root/bin`) containing all of the executables available from gems in the bundle. After using `--binstubs`, `bin/rspec spec/my_spec.rb` is identical to `bundle exec rspec spec/my_spec.rb`. ## ENVIRONMENT MODIFICATIONS `bundle exec` makes a number of changes to the shell environment, then executes the command you specify in full. * make sure that it's still possible to shell out to `bundle` from inside a command invoked by `bundle exec` (using `$BUNDLE_BIN_PATH`) * put the directory containing executables (like `rails`, `rspec`, `rackup`) for your bundle on `$PATH` * make sure that if bundler is invoked in the subshell, it uses the same `Gemfile` (by setting `BUNDLE_GEMFILE`) * add `-rbundler/setup` to `$RUBYOPT`, which makes sure that Ruby programs invoked in the subshell can see the gems in the bundle It also modifies Rubygems: * disallow loading additional gems not in the bundle * modify the `gem` method to be a no-op if a gem matching the requirements is in the bundle, and to raise a `Gem::LoadError` if it's not * Define `Gem.refresh` to be a no-op, since the source index is always frozen when using bundler, and to prevent gems from the system leaking into the environment * Override `Gem.bin_path` to use the gems in the bundle, making system executables work * Add all gems in the bundle into Gem.loaded_specs Finally, `bundle exec` also implicitly modifies `Gemfile.lock` if the lockfile and the Gemfile do not match. Bundler needs the Gemfile to determine things such as a gem's groups, `autorequire`, and platforms, etc., and that information isn't stored in the lockfile. The Gemfile and lockfile must be synced in order to `bundle exec` successfully, so `bundle exec` updates the lockfile beforehand. ### Loading By default, when attempting to `bundle exec` to a file with a ruby shebang, Bundler will `Kernel.load` that file instead of using `Kernel.exec`. For the vast majority of cases, this is a performance improvement. In a rare few cases, this could cause some subtle side-effects (such as dependence on the exact contents of `$0` or `__FILE__`) and the optimization can be disabled by enabling the `disable_exec_load` setting. ### Shelling out Any Ruby code that opens a subshell (like `system`, backticks, or `%x{}`) will automatically use the current Bundler environment. If you need to shell out to a Ruby command that is not part of your current bundle, use the `with_clean_env` method with a block. Any subshells created inside the block will be given the environment present before Bundler was activated. For example, Homebrew commands run Ruby, but don't work inside a bundle: Bundler.with_clean_env do `brew install wget` end Using `with_clean_env` is also necessary if you are shelling out to a different bundle. Any Bundler commands run in a subshell will inherit the current Gemfile, so commands that need to run in the context of a different bundle also need to use `with_clean_env`. Bundler.with_clean_env do Dir.chdir "/other/bundler/project" do `bundle exec ./script` end end Bundler provides convenience helpers that wrap `system` and `exec`, and they can be used like this: Bundler.clean_system('brew install wget') Bundler.clean_exec('brew install wget') ## RUBYGEMS PLUGINS At present, the Rubygems plugin system requires all files named `rubygems_plugin.rb` on the load path of _any_ installed gem when any Ruby code requires `rubygems.rb`. This includes executables installed into the system, like `rails`, `rackup`, and `rspec`. Since Rubygems plugins can contain arbitrary Ruby code, they commonly end up activating themselves or their dependencies. For instance, the `gemcutter 0.5` gem depended on `json_pure`. If you had that version of gemcutter installed (even if you _also_ had a newer version without this problem), Rubygems would activate `gemcutter 0.5` and `json_pure <latest>`. If your Gemfile(5) also contained `json_pure` (or a gem with a dependency on `json_pure`), the latest version on your system might conflict with the version in your Gemfile(5), or the snapshot version in your `Gemfile.lock`. If this happens, bundler will say: You have already activated json_pure 1.4.6 but your Gemfile requires json_pure 1.4.3. Consider using bundle exec. In this situation, you almost certainly want to remove the underlying gem with the problematic gem plugin. In general, the authors of these plugins (in this case, the `gemcutter` gem) have released newer versions that are more careful in their plugins. You can find a list of all the gems containing gem plugins by running ruby -rrubygems -e "puts Gem.find_files('rubygems_plugin.rb')" At the very least, you should remove all but the newest version of each gem plugin, and also remove all gem plugins that you aren't using (`gem uninstall gem_name`). gems/gems/bundler-2.2.33/lib/bundler/man/bundle-open.1 0000644 00000001105 15102661024 0016050 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-OPEN" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-open\fR \- Opens the source directory for a gem in your bundle . .SH "SYNOPSIS" \fBbundle open\fR [GEM] . .SH "DESCRIPTION" Opens the source directory of the provided GEM in your editor\. . .P For this to work the \fBEDITOR\fR or \fBBUNDLER_EDITOR\fR environment variable has to be set\. . .P Example: . .IP "" 4 . .nf bundle open \'rack\' . .fi . .IP "" 0 . .P Will open the source directory for the \'rack\' gem in your bundle\. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-pristine.1.ronn 0000644 00000002723 15102661024 0017726 0 ustar 00 bundle-pristine(1) -- Restores installed gems to their pristine condition =========================================================================== ## SYNOPSIS `bundle pristine` ## DESCRIPTION `pristine` restores the installed gems in the bundle to their pristine condition using the local gem cache from RubyGems. For git gems, a forced checkout will be performed. For further explanation, `bundle pristine` ignores unpacked files on disk. In other words, this command utilizes the local `.gem` cache or the gem's git repository as if one were installing from scratch. Note: the Bundler gem cannot be restored to its original state with `pristine`. One also cannot use `bundle pristine` on gems with a 'path' option in the Gemfile, because bundler has no original copy it can restore from. When is it practical to use `bundle pristine`? It comes in handy when a developer is debugging a gem. `bundle pristine` is a great way to get rid of experimental changes to a gem that one may not want. Why use `bundle pristine` over `gem pristine --all`? Both commands are very similar. For context: `bundle pristine`, without arguments, cleans all gems from the lockfile. Meanwhile, `gem pristine --all` cleans all installed gems for that Ruby version. If a developer forgets which gems in their project they might have been debugging, the Rubygems `gem pristine [GEMNAME]` command may be inconvenient. One can avoid waiting for `gem pristine --all`, and instead run `bundle pristine`. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-outdated.1.ronn 0000644 00000006727 15102661024 0017712 0 ustar 00 bundle-outdated(1) -- List installed gems with newer versions available ======================================================================= ## SYNOPSIS `bundle outdated` [GEM] [--local] [--pre] [--source] [--strict] [--parseable | --porcelain] [--group=GROUP] [--groups] [--update-strict] [--patch|--minor|--major] [--filter-major] [--filter-minor] [--filter-patch] [--only-explicit] ## DESCRIPTION Outdated lists the names and versions of gems that have a newer version available in the given source. Calling outdated with [GEM [GEM]] will only check for newer versions of the given gems. Prerelease gems are ignored by default. If your gems are up to date, Bundler will exit with a status of 0. Otherwise, it will exit 1. ## OPTIONS * `--local`: Do not attempt to fetch gems remotely and use the gem cache instead. * `--pre`: Check for newer pre-release gems. * `--source`: Check against a specific source. * `--strict`: Only list newer versions allowed by your Gemfile requirements. * `--parseable`, `--porcelain`: Use minimal formatting for more parseable output. * `--group`: List gems from a specific group. * `--groups`: List gems organized by groups. * `--update-strict`: Strict conservative resolution, do not allow any gem to be updated past latest --patch | --minor| --major. * `--minor`: Prefer updating only to next minor version. * `--major`: Prefer updating to next major version (default). * `--patch`: Prefer updating only to next patch version. * `--filter-major`: Only list major newer versions. * `--filter-minor`: Only list minor newer versions. * `--filter-patch`: Only list patch newer versions. * `--only-explicit`: Only list gems specified in your Gemfile, not their dependencies. ## PATCH LEVEL OPTIONS See [bundle update(1)](bundle-update.1.html) for details. One difference between the patch level options in `bundle update` and here is the `--strict` option. `--strict` was already an option on outdated before the patch level options were added. `--strict` wasn't altered, and the `--update-strict` option on `outdated` reflects what `--strict` does on `bundle update`. ## FILTERING OUTPUT The 3 filtering options do not affect the resolution of versions, merely what versions are shown in the output. If the regular output shows the following: * faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test" * hashie (newest 3.4.6, installed 1.2.0, requested = 1.2.0) in groups "default" * headless (newest 2.3.1, installed 2.2.3) in groups "test" `--filter-major` would only show: * hashie (newest 3.4.6, installed 1.2.0, requested = 1.2.0) in groups "default" `--filter-minor` would only show: * headless (newest 2.3.1, installed 2.2.3) in groups "test" `--filter-patch` would only show: * faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test" Filter options can be combined. `--filter-minor` and `--filter-patch` would show: * faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test" * headless (newest 2.3.1, installed 2.2.3) in groups "test" Combining all three `filter` options would be the same result as providing none of them. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-list.1.ronn 0000644 00000001424 15102661024 0017041 0 ustar 00 bundle-list(1) -- List all the gems in the bundle ========================================================================= ## SYNOPSIS `bundle list` [--name-only] [--paths] [--without-group=GROUP[ GROUP...]] [--only-group=GROUP[ GROUP...]] ## DESCRIPTION Prints a list of all the gems in the bundle including their version.

If this is the first time you run bundle install (and a `Gemfile.lock` does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems. If a `Gemfile.lock` does exist, and you have not updated your Gemfile(5), Bundler will fetch all remote sources, but use the dependencies specified in the `Gemfile.lock` instead of resolving dependencies. If a `Gemfile.lock` does exist, and you have updated your Gemfile(5), Bundler will use the dependencies in the `Gemfile.lock` for all gems that you did not update, but will re-resolve the dependencies of gems that you did update. You can find more information about this update process below under [CONSERVATIVE UPDATING][]. ## OPTIONS The `--clean`, `--deployment`, `--frozen`, `--no-prune`, `--path`, `--shebang`, `--system`, `--without` and `--with` options are deprecated because they only make sense if they are applied to every subsequent `bundle install` run automatically and that requires `bundler` to silently remember them. Since `bundler` will no longer remember CLI flags in future versions, `bundle config` (see bundle-config(1)) should be used to apply them permanently. * `--binstubs[=<directory>]`: Binstubs are scripts that wrap around executables. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it in `bin/`. This lets you link the binstub inside of an application to the exact gem version the application needs. Creates a directory (defaults to `~/bin`) and places any executables from the gem there. These executables run in Bundler's context. If used, you might add this directory to your environment's `PATH` variable. For instance, if the `rails` gem comes with a `rails` executable, this flag will create a `bin/rails` executable that ensures that all referred dependencies will be resolved using the bundled gems. * `--clean`: On finishing the installation Bundler is going to remove any gems not present in the current Gemfile(5). Don't worry, gems currently in use will not be removed. This option is deprecated in favor of the `clean` setting. * `--deployment`: In [deployment mode][DEPLOYMENT MODE], Bundler will 'roll-out' the bundle for production or CI use. Please check carefully if you want to have this option enabled in your development environment. This option is deprecated in favor of the `deployment` setting. * `--redownload`: Force download every gem, even if the required versions are already available locally. * `--frozen`: Do not allow the Gemfile.lock to be updated after this install. Exits non-zero if there are going to be changes to the Gemfile.lock. This option is deprecated in favor of the `frozen` setting. * `--full-index`: Bundler will not call Rubygems' API endpoint (default) but download and cache a (currently big) index file of all gems. Performance can be improved for large bundles that seldom change by enabling this option. * `--gemfile=<gemfile>`: The location of the Gemfile(5) which Bundler should use. This defaults to a Gemfile(5) in the current working directory. In general, Bundler will assume that the location of the Gemfile(5) is also the project's root and will try to find `Gemfile.lock` and `vendor/cache` relative to this location. * `--jobs=[<number>]`, `-j[<number>]`: The maximum number of parallel download and install jobs. The default is `1`. * `--local`: Do not attempt to connect to `rubygems.org`. Instead, Bundler will use the gems already present in Rubygems' cache or in `vendor/cache`. Note that if an appropriate platform-specific gem exists on `rubygems.org` it will not be found. * `--no-cache`: Do not update the cache in `vendor/cache` with the newly bundled gems. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install. * `--no-prune`: Don't remove stale gems from the cache when the installation finishes. This option is deprecated in favor of the `no_prune` setting. * `--path=<path>`: The location to install the specified gems to. This defaults to Rubygems' setting. Bundler shares this location with Rubygems, `gem install ...` will have gem installed there, too. Therefore, gems installed without a `--path ...` setting will show up by calling `gem list`. Accordingly, gems installed to other locations will not get listed. This option is deprecated in favor of the `path` setting. * `--quiet`: Do not print progress information to the standard output. Instead, Bundler will exit using a status code (`$?`). * `--retry=[<number>]`: Retry failed network or git requests for <number> times. * `--shebang=<ruby-executable>`: Uses the specified ruby executable (usually `ruby`) to execute the scripts created with `--binstubs`. In addition, if you use `--binstubs` together with `--shebang jruby` these executables will be changed to execute `jruby` instead. This option is deprecated in favor of the `shebang` setting. * `--standalone[=<list>]`: Makes a bundle that can work without depending on Rubygems or Bundler at runtime. A space separated list of groups to install has to be specified. Bundler creates a directory named `bundle` and installs the bundle there. It also generates a `bundle/bundler/setup.rb` file to replace Bundler's own setup in the manner required. Using this option implicitly sets `path`, which is a [remembered option][REMEMBERED OPTIONS]. * `--system`: Installs the gems specified in the bundle to the system's Rubygems location. This overrides any previous configuration of `--path`. This option is deprecated in favor of the `system` setting. * `--trust-policy=[<policy>]`: Apply the Rubygems security policy <policy>, where policy is one of `HighSecurity`, `MediumSecurity`, `LowSecurity`, `AlmostNoSecurity`, or `NoSecurity`. For more details, please see the Rubygems signing documentation linked below in [SEE ALSO][]. * `--with=<list>`: A space-separated list of groups referencing gems to install. If an optional group is given it is installed. If a group is given that is in the remembered list of groups given to --without, it is removed from that list. This option is deprecated in favor of the `with` setting. * `--without=<list>`: A space-separated list of groups referencing gems to skip during installation. If a group is given that is in the remembered list of groups given to --with, it is removed from that list. This option is deprecated in favor of the `without` setting. ## DEPLOYMENT MODE Bundler's defaults are optimized for development. To switch to defaults optimized for deployment and for CI, use the `--deployment` flag. Do not activate deployment mode on development machines, as it will cause an error when the Gemfile(5) is modified. 1. A `Gemfile.lock` is required. To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a `Gemfile.lock` is required. This is mainly to ensure that you remember to check your `Gemfile.lock` into version control. 2. The `Gemfile.lock` must be up to date In development, you can modify your Gemfile(5) and re-run `bundle install` to [conservatively update][CONSERVATIVE UPDATING] your `Gemfile.lock` snapshot. In deployment, your `Gemfile.lock` should be up-to-date with changes made in your Gemfile(5). 3. Gems are installed to `vendor/bundle` not your default system location In development, it's convenient to share the gems used in your application with other applications and other scripts that run on the system. In deployment, isolation is a more important default. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them. As a result, `bundle install --deployment` installs gems to the `vendor/bundle` directory in the application. This may be overridden using the `--path` option. ## SUDO USAGE By default, Bundler installs gems to the same location as `gem install`. In some cases, that location may not be writable by your Unix user. In that case, Bundler will stage everything in a temporary directory, then ask you for your `sudo` password in order to copy the gems into their system location. From your perspective, this is identical to installing the gems directly into the system. You should never use `sudo bundle install`. This is because several other steps in `bundle install` must be performed as the current user: * Updating your `Gemfile.lock` * Updating your `vendor/cache`, if necessary * Checking out private git repositories using your user's SSH keys Of these three, the first two could theoretically be performed by `chown`ing the resulting files to `$SUDO_USER`. The third, however, can only be performed by invoking the `git` command as the current user. Therefore, git gems are downloaded and installed into `~/.bundle` rather than $GEM_HOME or $BUNDLE_PATH. As a result, you should run `bundle install` as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location. ## INSTALLING GROUPS By default, `bundle install` will install all gems in all groups in your Gemfile(5), except those declared for a different platform. However, you can explicitly tell Bundler to skip installing certain groups with the `--without` option. This option takes a space-separated list of groups. While the `--without` option will skip _installing_ the gems in the specified groups, it will still _download_ those gems and use them to resolve the dependencies of every gem in your Gemfile(5). This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against. `Bundler offers a rock-solid guarantee that the third-party code you are running in development and testing is also the third-party code you are running in production. You can choose to exclude some of that code in different environments, but you will never be caught flat-footed by different versions of third-party code being used in different environments.` For a simple illustration, consider the following Gemfile(5): source 'https://rubygems.org' gem 'sinatra' group :production do gem 'rack-perftools-profiler' end In this case, `sinatra` depends on any version of Rack (`>= 1.0`), while `rack-perftools-profiler` depends on 1.x (`~> 1.0`). When you run `bundle install --without production` in development, we look at the dependencies of `rack-perftools-profiler` as well. That way, you do not spend all your time developing against Rack 2.0, using new APIs unavailable in Rack 1.x, only to have Bundler switch to Rack 1.2 when the `production` group _is_ used. This should not cause any problems in practice, because we do not attempt to `install` the gems in the excluded groups, and only evaluate as part of the dependency resolution process. This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using. ## THE GEMFILE.LOCK When you run `bundle install`, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called `Gemfile.lock`. Bundler uses this file in all subsequent calls to `bundle install`, which guarantees that you always use the same exact code, even as your application moves across machines. Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies. As a result, you `SHOULD` check your `Gemfile.lock` into version control, in both applications and gems. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third-party code being used if `any` of the gems in the Gemfile(5) or any of their dependencies have been updated. When Bundler first shipped, the `Gemfile.lock` was included in the `.gitignore` file included with generated gems. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem. Since `bundle install` is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems. ## CONSERVATIVE UPDATING When you make a change to the Gemfile(5) and then run `bundle install`, Bundler will update only the gems that you modified. In other words, if a gem that you `did not modify` worked before you called `bundle install`, it will continue to use the exact same versions of all dependencies as it used before the update. Let's take a look at an example. Here's your original Gemfile(5): source 'https://rubygems.org' gem 'actionpack', '2.3.8' gem 'activemerchant' In this case, both `actionpack` and `activemerchant` depend on `activesupport`. The `actionpack` gem depends on `activesupport 2.3.8` and `rack ~> 1.1.0`, while the `activemerchant` gem depends on `activesupport >= 2.3.2`, `braintree >= 2.0.0`, and `builder >= 2.0.0`. When the dependencies are first resolved, Bundler will select `activesupport 2.3.8`, which satisfies the requirements of both gems in your Gemfile(5). Next, you modify your Gemfile(5) to: source 'https://rubygems.org' gem 'actionpack', '3.0.0.rc' gem 'activemerchant' The `actionpack 3.0.0.rc` gem has a number of new dependencies, and updates the `activesupport` dependency to `= 3.0.0.rc` and the `rack` dependency to `~> 1.2.1`. When you run `bundle install`, Bundler notices that you changed the `actionpack` gem, but not the `activemerchant` gem. It evaluates the gems currently being used to satisfy its requirements: * `activesupport 2.3.8`: also used to satisfy a dependency in `activemerchant`, which is not being updated * `rack ~> 1.1.0`: not currently being used to satisfy another dependency Because you did not explicitly ask to update `activemerchant`, you would not expect it to suddenly stop working after updating `actionpack`. However, satisfying the new `activesupport 3.0.0.rc` dependency of actionpack requires updating one of its dependencies. Even though `activemerchant` declares a very loose dependency that theoretically matches `activesupport 3.0.0.rc`, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies. In this case, the `activemerchant` dependency is treated as `activemerchant 1.7.1 + activesupport 2.3.8`, so `bundle install` will report that it cannot update `actionpack`. To explicitly update `actionpack`, including its dependencies which other gems in the Gemfile(5) still depend on, run `bundle update actionpack` (see `bundle update(1)`). `Summary`: In general, after making a change to the Gemfile(5) , you should first try to run `bundle install`, which will guarantee that no other gem in the Gemfile(5) is impacted by the change. If that does not work, run [bundle update(1)](bundle-update.1.html). ## SEE ALSO * [Gem install docs](http://guides.rubygems.org/rubygems-basics/#installing-gems) * [Rubygems signing docs](http://guides.rubygems.org/security/) gems/gems/bundler-2.2.33/lib/bundler/man/bundle-pristine.1 0000644 00000003216 15102661024 0016751 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-PRISTINE" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-pristine\fR \- Restores installed gems to their pristine condition . .SH "SYNOPSIS" \fBbundle pristine\fR . .SH "DESCRIPTION" \fBpristine\fR restores the installed gems in the bundle to their pristine condition using the local gem cache from RubyGems\. For git gems, a forced checkout will be performed\. . .P For further explanation, \fBbundle pristine\fR ignores unpacked files on disk\. In other words, this command utilizes the local \fB\.gem\fR cache or the gem\'s git repository as if one were installing from scratch\. . .P Note: the Bundler gem cannot be restored to its original state with \fBpristine\fR\. One also cannot use \fBbundle pristine\fR on gems with a \'path\' option in the Gemfile, because bundler has no original copy it can restore from\. . .P When is it practical to use \fBbundle pristine\fR? . .P It comes in handy when a developer is debugging a gem\. \fBbundle pristine\fR is a great way to get rid of experimental changes to a gem that one may not want\. . .P Why use \fBbundle pristine\fR over \fBgem pristine \-\-all\fR? . .P Both commands are very similar\. For context: \fBbundle pristine\fR, without arguments, cleans all gems from the lockfile\.

Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it into \fBbin/\fR\. Binstubs are a shortcut\-or alternative\- to always using \fBbundle exec\fR\. This gives you a file that can be run directly, and one that will always run the correct gem version used by the application\. . .P For example, if you run \fBbundle binstubs rspec\-core\fR, Bundler will create the file \fBbin/rspec\fR\. That file will contain enough code to load Bundler, tell it to load the bundled gems, and then run rspec\. . .P This command generates binstubs for executables in \fBGEM_NAME\fR\.

If these options must be remembered, it\'s better to set them using \fBbundle config\fR (e\.g\., \fBbundle config set \-\-local path foo\fR)\. . .P The options that can be configured are: . .TP \fBbin\fR Creates a directory (defaults to \fB~/bin\fR) and place any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\. . .TP \fBdeployment\fR In deployment mode, Bundler will \'roll\-out\' the bundle for \fBproduction\fR use\. Please check carefully if you want to have this option enabled in \fBdevelopment\fR or \fBtest\fR environments\. . .TP \fBpath\fR The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\. . .TP \fBwithout\fR A space\-separated list of groups referencing gems to skip during installation\. . .TP \fBwith\fR A space\-separated list of groups referencing gems to include during installation\. . .SH "BUILD OPTIONS" You can use \fBbundle config\fR to give Bundler the flags to pass to the gem installer every time bundler tries to install a particular gem\. . .P A very common example, the \fBmysql\fR gem, requires Snow Leopard users to pass configuration flags to \fBgem install\fR to specify where to find the \fBmysql_config\fR executable\. . .IP "" 4 . .nf gem install mysql \-\- \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config . .fi . .IP "" 0 . .P Since the specific location of that executable can change from machine to machine, you can specify these flags on a per\-machine basis\. . .IP "" 4 . .nf bundle config set \-\-global build\.mysql \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config . .fi . .IP "" 0 . .P After running this command, every time bundler needs to install the \fBmysql\fR gem, it will pass along the flags you specified\. . .SH "CONFIGURATION KEYS" Configuration keys in bundler have two forms: the canonical form and the environment variable form\. . .P For instance, passing the \fB\-\-without\fR flag to bundle install(1) \fIbundle\-install\.1\.html\fR prevents Bundler from installing certain groups specified in the Gemfile(5)\. Bundler persists this value in \fBapp/\.bundle/config\fR so that calls to \fBBundler\.setup\fR do not try to find gems from the \fBGemfile\fR that you didn\'t install\. Additionally, subsequent calls to bundle install(1) \fIbundle\-install\.1\.html\fR remember this setting and skip those groups\. . .P The canonical form of this configuration is \fB"without"\fR\. To convert the canonical form to the environment variable form, capitalize it, and prepend \fBBUNDLE_\fR\. The environment variable form of \fB"without"\fR is \fBBUNDLE_WITHOUT\fR\. . .P Any periods in the configuration keys must be replaced with two underscores when setting it via environment variables\.

If you use both, environment variables will take preference over global settings\. . .SH "LOCAL GIT REPOS" Bundler also allows you to work against a git repository locally instead of using the remote version\. This can be achieved by setting up a local override: . .IP "" 4 . .nf bundle config set \-\-local local\.GEM_NAME /path/to/local/git/repository . .fi . .IP "" 0 . .P For example, in order to use a local Rack repository, a developer could call: . .IP "" 4 . .nf bundle config set \-\-local local\.rack ~/Work/git/rack . .fi . .IP "" 0 . .P Now instead of checking out the remote git repository, the local override will be used\. Similar to a path source, every time the local git repository change, changes will be automatically picked up by Bundler\. This means a commit in the local git repo will update the revision in the \fBGemfile\.lock\fR to the local git repo revision\. This requires the same attention as git submodules\. Before pushing to the remote, you need to ensure the local override was pushed, otherwise you may point to a commit that only exists in your local machine\. You\'ll also need to CGI escape your usernames and passwords as well\. . .P Bundler does many checks to ensure a developer won\'t work with invalid references\. Particularly, we force a developer to specify a branch in the \fBGemfile\fR in order to use this feature\. If the branch specified in the \fBGemfile\fR and the current branch in the local git repository do not match, Bundler will abort\. This ensures that a developer is always working against the correct branches, and prevents accidental locking to a different branch\. . .P Finally, Bundler also ensures that the current revision in the \fBGemfile\.lock\fR exists in the local git repository\. By doing this, Bundler forces you to fetch the latest changes in the remotes\. . .SH "MIRRORS OF GEM SOURCES" Bundler supports overriding gem sources with mirrors\. This allows you to configure rubygems\.org as the gem source in your Gemfile while still using your mirror to fetch gems\. . .IP "" 4 . .nf bundle config set \-\-global mirror\.SOURCE_URL MIRROR_URL . .fi . .IP "" 0 . .P For example, to use a mirror of rubygems\.org hosted at rubygems\-mirror\.org: . .IP "" 4 . .nf bundle config set \-\-global mirror\.http://rubygems\.org http://rubygems\-mirror\.org . .fi . .IP "" 0 . .P Each mirror also provides a fallback timeout setting\. If the mirror does not respond within the fallback timeout, Bundler will try to use the original server instead of the mirror\. . .IP "" 4 . .nf bundle config set \-\-global mirror\.SOURCE_URL\.fallback_timeout TIMEOUT . .fi . .IP "" 0 . .P For example, to fall back to rubygems\.org after 3 seconds: . .IP "" 4 . .nf bundle config set \-\-global mirror\.https://rubygems\.org\.fallback_timeout 3 . .fi . .IP "" 0 . .P The default fallback timeout is 0\.1 seconds, but the setting can currently only accept whole seconds (for example, 1, 15, or 30)\. . .SH "CREDENTIALS FOR GEM SOURCES" Bundler allows you to configure credentials for any gem source, which allows you to avoid putting secrets into your Gemfile\. . .IP "" 4 . .nf bundle config set \-\-global SOURCE_HOSTNAME USERNAME:PASSWORD . .fi . .IP "" 0 . .P For example, to save the credentials of user \fBclaudette\fR for the gem source at \fBgems\.longerous\.com\fR, you would run: . .IP "" 4 . .nf bundle config set \-\-global gems\.longerous\.com claudette:s00pers3krit . .fi . .IP "" 0 . .P Or you can set the credentials as an environment variable like this: . .IP "" 4 . .nf export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit" . .fi . .IP "" 0 . .P For gems with a git source with HTTP(S) URL you can specify credentials like so: . .IP "" 4 . .nf bundle config set \-\-global https://github\.com/rubygems/rubygems\.git username:password . .fi . .IP "" 0 . .P Or you can set the credentials as an environment variable like so: . .IP "" 4 . .nf export BUNDLE_GITHUB__COM=username:password . .fi . .IP "" 0 . .P This is especially useful for private repositories on hosts such as Github, where you can use personal OAuth tokens: . .IP "" 4 . .nf export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x\-oauth\-basic . .fi . .IP "" 0 . .P Note that any configured credentials will be redacted by informative commands such as \fBbundle config list\fR or \fBbundle config get\fR, unless you use the \fB\-\-parseable\fR flag\. This is to avoid unintentionally leaking credentials when copy\-pasting bundler output\. . .P Also note that to guarantee a sane mapping between valid environment variable names and valid host names, bundler makes the following transformations: . .IP "\(bu" 4 Any \fB\-\fR characters in a host name are mapped to a triple dash (\fB___\fR) in the corresponding environment variable\. . .IP "\(bu" 4 Any \fB\.\fR characters in a host name are mapped to a double dash (\fB__\fR) in the corresponding environment variable\. . .IP "" 0 . .P This means that if you have a gem server named \fBmy\.gem\-host\.com\fR, you\'ll need to use the \fBBUNDLE_MY__GEM___HOST__COM\fR variable to configure credentials for it through ENV\. . .SH "CONFIGURE BUNDLER DIRECTORIES" Bundler\'s home, config, cache and plugin directories are able to be configured through environment variables\.

Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it into `bin/`. Binstubs are a shortcut-or alternative- to always using `bundle exec`. This gives you a file that can be run directly, and one that will always run the correct gem version used by the application. For example, if you run `bundle binstubs rspec-core`, Bundler will create the file `bin/rspec`. That file will contain enough code to load Bundler, tell it to load the bundled gems, and then run rspec. This command generates binstubs for executables in `GEM_NAME`. Binstubs are put into `bin`, or the `--path` directory if one has been set. Calling binstubs with [GEM [GEM]] will create binstubs for all given gems. ## OPTIONS * `--force`: Overwrite existing binstubs if they exist. * `--path`: The location to install the specified binstubs to. This defaults to `bin`. * `--standalone`: Makes binstubs that can work without depending on Rubygems or Bundler at runtime. * `--shebang`: Specify a different shebang executable name than the default (default 'ruby') * `--all`: Create binstubs for all gems in the bundle. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-list.1 0000644 00000001705 15102661024 0016070 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-LIST" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-list\fR \- List all the gems in the bundle . .SH "SYNOPSIS" \fBbundle list\fR [\-\-name\-only] [\-\-paths] [\-\-without\-group=GROUP[ GROUP\.\.\.]] [\-\-only\-group=GROUP[ GROUP\.\.\.]] . .SH "DESCRIPTION" Prints a list of all the gems in the bundle including their version\. . .P Example: . .P bundle list \-\-name\-only . .P bundle list \-\-paths . .P bundle list \-\-without\-group test . .P bundle list \-\-only\-group dev . .P bundle list \-\-only\-group dev test \-\-paths . .SH "OPTIONS" . .TP \fB\-\-name\-only\fR Print only the name of each gem\. . .TP \fB\-\-paths\fR Print the path to each gem in the bundle\. . .TP \fB\-\-without\-group=<list>\fR A space\-separated list of groups of gems to skip during printing\. . .TP \fB\-\-only\-group=<list>\fR A space\-separated list of groups of gems to print\. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-init.1.ronn 0000644 00000001653 15102661024 0017035 0 ustar 00 bundle-init(1) -- Generates a Gemfile into the current working directory ======================================================================== ## SYNOPSIS `bundle init` [--gemspec=FILE] ## DESCRIPTION Init generates a default [`Gemfile(5)`][Gemfile(5)] in the current working directory.

Place the `Gemfile` in the root of the directory containing the associated code. For instance, in a Rails application, place the `Gemfile` in the same directory as the `Rakefile`. ## SYNTAX A `Gemfile` is evaluated as Ruby code, in a context which makes available a number of methods used to describe the gem requirements. ## GLOBAL SOURCES At the top of the `Gemfile`, add a line for the `Rubygems` source that contains the gems listed in the `Gemfile`. source "https://rubygems.org" It is possible, but not recommended as of Bundler 1.7, to add multiple global `source` lines. Each of these `source`s `MUST` be a valid Rubygems repository. Sources are checked for gems following the heuristics described in [SOURCE PRIORITY][]. If a gem is found in more than one global source, Bundler will print a warning after installing the gem indicating which source was used, and listing the other sources where the gem is available. A specific source can be selected for gems that need to use a non-standard repository, suppressing this warning, by using the [`:source` option](#SOURCE) or a [`source` block](#BLOCK-FORM-OF-SOURCE-GIT-PATH-GROUP-and-PLATFORMS). ### CREDENTIALS Some gem sources require a username and password. Use [bundle config(1)](bundle-config.1.html) to set the username and password for any of the sources that need it. The command must be run once on each computer that will install the Gemfile, but this keeps the credentials from being stored in plain text in version control. bundle config gems.example.com user:password For some sources, like a company Gemfury account, it may be easier to include the credentials in the Gemfile as part of the source URL. source "https://user:password@gems.example.com" Credentials in the source URL will take precedence over credentials set using `config`. ## RUBY If your application requires a specific Ruby version or engine, specify your requirements using the `ruby` method, with the following arguments. All parameters are `OPTIONAL` unless otherwise specified. ### VERSION (required) The version of Ruby that your application requires. If your application requires an alternate Ruby engine, such as JRuby, Rubinius or TruffleRuby, this should be the Ruby version that the engine is compatible with. ruby "1.9.3" ### ENGINE Each application _may_ specify a Ruby engine. If an engine is specified, an engine version _must_ also be specified. What exactly is an Engine? - A Ruby engine is an implementation of the Ruby language. - For background: the reference or original implementation of the Ruby programming language is called [Matz's Ruby Interpreter](https://en.wikipedia.org/wiki/Ruby_MRI), or MRI for short. This is named after Ruby creator Yukihiro Matsumoto, also known as Matz. MRI is also known as CRuby, because it is written in C. MRI is the most widely used Ruby engine. - [Other implementations](https://www.ruby-lang.org/en/about/) of Ruby exist. Some of the more well-known implementations include [Rubinius](https://rubinius.com/), and [JRuby](http://jruby.org/). Rubinius is an alternative implementation of Ruby written in Ruby. JRuby is an implementation of Ruby on the JVM, short for Java Virtual Machine. ### ENGINE VERSION Each application _may_ specify a Ruby engine version. If an engine version is specified, an engine _must_ also be specified. If the engine is "ruby" the engine version specified _must_ match the Ruby version. ruby "1.8.7", :engine => "jruby", :engine_version => "1.6.7" ### PATCHLEVEL Each application _may_ specify a Ruby patchlevel. ruby "2.0.0", :patchlevel => "247" ## GEMS Specify gem requirements using the `gem` method, with the following arguments. All parameters are `OPTIONAL` unless otherwise specified. ### NAME (required) For each gem requirement, list a single _gem_ line. gem "nokogiri" ### VERSION Each _gem_ `MAY` have one or more version specifiers. gem "nokogiri", ">= 1.4.2" gem "RedCloth", ">= 4.1.0", "< 4.2.0" ### REQUIRE AS Each _gem_ `MAY` specify files that should be used when autorequiring via `Bundler.require`. You may pass an array with multiple files or `true` if the file you want `required` has the same name as _gem_ or `false` to prevent any file from being autorequired. gem "redis", :require => ["redis/connection/hiredis", "redis"] gem "webmock", :require => false gem "byebug", :require => true The argument defaults to the name of the gem. For example, these are identical: gem "nokogiri" gem "nokogiri", :require => "nokogiri" gem "nokogiri", :require => true ### GROUPS Each _gem_ `MAY` specify membership in one or more groups. Any _gem_ that does not specify membership in any group is placed in the `default` group. gem "rspec", :group => :test gem "wirble", :groups => [:development, :test] The Bundler runtime allows its two main methods, `Bundler.setup` and `Bundler.require`, to limit their impact to particular groups. # setup adds gems to Ruby's load path Bundler.setup # defaults to all groups require "bundler/setup" # same as Bundler.setup Bundler.setup(:default) # only set up the _default_ group Bundler.setup(:test) # only set up the _test_ group (but `not` _default_) Bundler.setup(:default, :test) # set up the _default_ and _test_ groups, but no others # require requires all of the gems in the specified groups Bundler.require # defaults to the _default_ group Bundler.require(:default) # identical Bundler.require(:default, :test) # requires the _default_ and _test_ groups Bundler.require(:test) # requires the _test_ group The Bundler CLI allows you to specify a list of groups whose gems `bundle install` should not install with the `without` configuration. To specify multiple groups to ignore, specify a list of groups separated by spaces. bundle config set --local without test bundle config set --local without development test Also, calling `Bundler.setup` with no parameters, or calling `require "bundler/setup"` will setup all groups except for the ones you excluded via `--without` (since they are not available). Note that on `bundle install`, bundler downloads and evaluates all gems, in order to create a single canonical list of all of the required gems and their dependencies. This means that you cannot list different versions of the same gems in different groups. For more details, see [Understanding Bundler](https://bundler.io/rationale.html). ### PLATFORMS If a gem should only be used in a particular platform or set of platforms, you can specify them. Platforms are essentially identical to groups, except that you do not need to use the `--without` install-time flag to exclude groups of gems for other platforms. There are a number of `Gemfile` platforms: * `ruby`: C Ruby (MRI), Rubinius or TruffleRuby, but `NOT` Windows * `mri`: Same as _ruby_, but only C Ruby (MRI) * `mingw`: Windows 32 bit 'mingw32' platform (aka RubyInstaller) * `x64_mingw`: Windows 64 bit 'mingw32' platform (aka RubyInstaller x64) * `rbx`: Rubinius * `jruby`: JRuby * `truffleruby`: TruffleRuby * `mswin`: Windows You can restrict further by platform and version for all platforms *except* for `rbx`, `jruby`, `truffleruby` and `mswin`. To specify a version in addition to a platform, append the version number without the delimiter to the platform. For example, to specify that a gem should only be used on platforms with Ruby 2.3, use: ruby_23 The full list of platforms and supported versions includes: * `ruby`: 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 * `mri`: 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 * `mingw`: 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 * `x64_mingw`: 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 As with groups, you can specify one or more platforms: gem "weakling", :platforms => :jruby gem "ruby-debug", :platforms => :mri_18 gem "nokogiri", :platforms => [:mri_18, :jruby] All operations involving groups ([`bundle install`](bundle-install.1.html), `Bundler.setup`, `Bundler.require`) behave exactly the same as if any groups not matching the current platform were explicitly excluded. ### SOURCE You can select an alternate Rubygems repository for a gem using the ':source' option. gem "some_internal_gem", :source => "https://gems.example.com" This forces the gem to be loaded from this source and ignores any global sources declared at the top level of the file. If the gem does not exist in this source, it will not be installed. Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on global sources using the ordering described in [SOURCE PRIORITY][]. Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in [GLOBAL SOURCES (#source)](#GLOBAL-SOURCES). Using the `:source` option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources. ### GIT If necessary, you can specify that a gem is located at a particular git repository using the `:git` parameter. The repository can be accessed via several protocols: * `HTTP(S)`: gem "rails", :git => "https://github.com/rails/rails.git" * `SSH`: gem "rails", :git => "git@github.com:rails/rails.git" * `git`: gem "rails", :git => "git://github.com/rails/rails.git" If using SSH, the user that you use to run `bundle install` `MUST` have the appropriate keys available in their `$HOME/.ssh`. `NOTE`: `http://` and `git://` URLs should be avoided if at all possible. These protocols are unauthenticated, so a man-in-the-middle attacker can deliver malicious code and compromise your system. HTTPS and SSH are strongly preferred. The `group`, `platforms`, and `require` options are available and behave exactly the same as they would for a normal gem. A git repository `SHOULD` have at least one file, at the root of the directory containing the gem, with the extension `.gemspec`. This file `MUST` contain a valid gem specification, as expected by the `gem build` command. If a git repository does not have a `.gemspec`, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions. As a result, it may fail to properly integrate into your application. If a git repository does have a `.gemspec` for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the `.gemspec` specifies a version matching the version specifier. If not, bundler will print a warning. gem "rails", "2.3.8", :git => "https://github.com/rails/rails.git" # bundle install will fail, because the .gemspec in the rails # repository's master branch specifies version 3.0.0 If a git repository does `not` have a `.gemspec` for the gem you attached it to, a version specifier `MUST` be provided. Bundler will use this version in the simple `.gemspec` it creates. Git repositories support a number of additional options. * `branch`, `tag`, and `ref`: You `MUST` only specify at most one of these options. The default is `:branch => "master"`. For example: gem "rails", :git => "https://github.com/rails/rails.git", :branch => "5-0-stable" gem "rails", :git => "https://github.com/rails/rails.git", :tag => "v5.0.0" gem "rails", :git => "https://github.com/rails/rails.git", :ref => "4aded" * `submodules`: For reference, a [git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) lets you have another git repository within a subfolder of your repository. Specify `:submodules => true` to cause bundler to expand any submodules included in the git repository If a git repository contains multiple `.gemspecs`, each `.gemspec` represents a gem located at the same place in the file system as the `.gemspec`. |~rails [git root] | |-rails.gemspec [rails gem located here] |~actionpack | |-actionpack.gemspec [actionpack gem located here] |~activesupport | |-activesupport.gemspec [activesupport gem located here] |... To install a gem located in a git repository, bundler changes to the directory containing the gemspec, runs `gem build name.gemspec` and then installs the resulting gem. The `gem build` command, which comes standard with Rubygems, evaluates the `.gemspec` in the context of the directory in which it is located. ### GIT SOURCE A custom git source can be defined via the `git_source` method. Provide the source's name as an argument, and a block which receives a single argument and interpolates it into a string to return the full repo address: git_source(:stash){ |repo_name| "https://stash.corp.acme.pl/#{repo_name}.git" } gem 'rails', :stash => 'forks/rails' In addition, if you wish to choose a specific branch: gem "rails", :stash => "forks/rails", :branch => "branch_name" ### GITHUB `NOTE`: This shorthand should be avoided until Bundler 2.0, since it currently expands to an insecure `git://` URL. This allows a man-in-the-middle attacker to compromise your system. If the git repository you want to use is hosted on GitHub and is public, you can use the :github shorthand to specify the github username and repository name (without the trailing ".git"), separated by a slash. If both the username and repository name are the same, you can omit one. gem "rails", :github => "rails/rails" gem "rails", :github => "rails" Are both equivalent to gem "rails", :git => "git://github.com/rails/rails.git" Since the `github` method is a specialization of `git_source`, it accepts a `:branch` named argument. You can also directly pass a pull request URL: gem "rails", :github => "https://github.com/rails/rails/pull/43753" Which is equivalent to: gem "rails", :github => "rails/rails", branch: "refs/pull/43753/head" ### GIST If the git repository you want to use is hosted as a Github Gist and is public, you can use the :gist shorthand to specify the gist identifier (without the trailing ".git"). gem "the_hatch", :gist => "4815162342" Is equivalent to: gem "the_hatch", :git => "https://gist.github.com/4815162342.git" Since the `gist` method is a specialization of `git_source`, it accepts a `:branch` named argument. ### BITBUCKET If the git repository you want to use is hosted on Bitbucket and is public, you can use the :bitbucket shorthand to specify the bitbucket username and repository name (without the trailing ".git"), separated by a slash. If both the username and repository name are the same, you can omit one. gem "rails", :bitbucket => "rails/rails" gem "rails", :bitbucket => "rails" Are both equivalent to gem "rails", :git => "https://rails@bitbucket.org/rails/rails.git" Since the `bitbucket` method is a specialization of `git_source`, it accepts a `:branch` named argument. ### PATH You can specify that a gem is located in a particular location on the file system. Relative paths are resolved relative to the directory containing the `Gemfile`. Similar to the semantics of the `:git` option, the `:path` option requires that the directory in question either contains a `.gemspec` for the gem, or that you specify an explicit version that bundler should use. Unlike `:git`, bundler does not compile C extensions for gems specified as paths. gem "rails", :path => "vendor/rails" If you would like to use multiple local gems directly from the filesystem, you can set a global `path` option to the path containing the gem's files. This will automatically load gemspec files from subdirectories. path 'components' do gem 'admin_ui' gem 'public_ui' end ## BLOCK FORM OF SOURCE, GIT, PATH, GROUP and PLATFORMS The `:source`, `:git`, `:path`, `:group`, and `:platforms` options may be applied to a group of gems by using block form. source "https://gems.example.com" do gem "some_internal_gem" gem "another_internal_gem" end git "https://github.com/rails/rails.git" do gem "activesupport" gem "actionpack" end platforms :ruby do gem "ruby-debug" gem "sqlite3" end group :development, :optional => true do gem "wirble" gem "faker" end In the case of the group block form the :optional option can be given to prevent a group from being installed unless listed in the `--with` option given to the `bundle install` command. In the case of the `git` block form, the `:ref`, `:branch`, `:tag`, and `:submodules` options may be passed to the `git` method, and all gems in the block will inherit those options. The presence of a `source` block in a Gemfile also makes that source available as a possible global source for any other gems which do not specify explicit sources. Thus, when defining source blocks, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources, either via source blocks or `:source` directives on individual gems. ## INSTALL_IF The `install_if` method allows gems to be installed based on a proc or lambda. This is especially useful for optional gems that can only be used if certain software is installed or some other conditions are met. install_if -> { RUBY_PLATFORM =~ /darwin/ } do gem "pasteboard" end ## GEMSPEC The [`.gemspec`](http://guides.rubygems.org/specification-reference/) file is where you provide metadata about your gem to Rubygems. Some required Gemspec attributes include the name, description, and homepage of your gem. This is also where you specify the dependencies your gem needs to run. If you wish to use Bundler to help install dependencies for a gem while it is being developed, use the `gemspec` method to pull in the dependencies listed in the `.gemspec` file. The `gemspec` method adds any runtime dependencies as gem requirements in the default group. It also adds development dependencies as gem requirements in the `development` group. Finally, it adds a gem requirement on your project (`:path => '.'`). In conjunction with `Bundler.setup`, this allows you to require project files in your test code as you would if the project were installed as a gem; you need not manipulate the load path manually or require project files via relative paths. The `gemspec` method supports optional `:path`, `:glob`, `:name`, and `:development_group` options, which control where bundler looks for the `.gemspec`, the glob it uses to look for the gemspec (defaults to: "{,*,*/*}.gemspec"), what named `.gemspec` it uses (if more than one is present), and which group development dependencies are included in. When a `gemspec` dependency encounters version conflicts during resolution, the local version under development will always be selected -- even if there are remote versions that better match other requirements for the `gemspec` gem. ## SOURCE PRIORITY When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order: 1. The source explicitly attached to the gem (using `:source`, `:path`, or `:git`) 2. For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent. This results in bundler prioritizing the ActiveSupport gem from the Rails git repository over ones from `rubygems.org` 3. The sources specified via global `source` lines, searching each source in your `Gemfile` from last added to first added. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-install.1 0000644 00000043110 15102661024 0016557 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "BUNDLE\-INSTALL" "1" "December 2021" "" "" . .SH "NAME" \fBbundle\-install\fR \- Install the dependencies specified in your Gemfile . .SH "SYNOPSIS" \fBbundle install\fR [\-\-binstubs[=DIRECTORY]] [\-\-clean] [\-\-deployment] [\-\-frozen] [\-\-full\-index] [\-\-gemfile=GEMFILE] [\-\-jobs=NUMBER] [\-\-local] [\-\-no\-cache] [\-\-no\-prune] [\-\-path PATH] [\-\-quiet] [\-\-redownload] [\-\-retry=NUMBER] [\-\-shebang] [\-\-standalone[=GROUP[ GROUP\.\.\.]]] [\-\-system] [\-\-trust\-policy=POLICY] [\-\-with=GROUP[ GROUP\.\.\.]] [\-\-without=GROUP[ GROUP\.\.\.]] . .SH "DESCRIPTION" Install the gems specified in your Gemfile(5)\. If this is the first time you run bundle install (and a \fBGemfile\.lock\fR does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems\. . .P If a \fBGemfile\.lock\fR does exist, and you have not updated your Gemfile(5), Bundler will fetch all remote sources, but use the dependencies specified in the \fBGemfile\.lock\fR instead of resolving dependencies\. . .P If a \fBGemfile\.lock\fR does exist, and you have updated your Gemfile(5), Bundler will use the dependencies in the \fBGemfile\.lock\fR for all gems that you did not update, but will re\-resolve the dependencies of gems that you did update\. You can find more information about this update process below under \fICONSERVATIVE UPDATING\fR\. . .SH "OPTIONS" The \fB\-\-clean\fR, \fB\-\-deployment\fR, \fB\-\-frozen\fR, \fB\-\-no\-prune\fR, \fB\-\-path\fR, \fB\-\-shebang\fR, \fB\-\-system\fR, \fB\-\-without\fR and \fB\-\-with\fR options are deprecated because they only make sense if they are applied to every subsequent \fBbundle install\fR run automatically and that requires \fBbundler\fR to silently remember them\. Since \fBbundler\fR will no longer remember CLI flags in future versions, \fBbundle config\fR (see bundle\-config(1)) should be used to apply them permanently\. . .TP \fB\-\-binstubs[=<directory>]\fR Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it in \fBbin/\fR\. This lets you link the binstub inside of an application to the exact gem version the application needs\. . .IP Creates a directory (defaults to \fB~/bin\fR) and places any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\. . .TP \fB\-\-clean\fR On finishing the installation Bundler is going to remove any gems not present in the current Gemfile(5)\. Don\'t worry, gems currently in use will not be removed\. . .IP This option is deprecated in favor of the \fBclean\fR setting\. . .TP \fB\-\-deployment\fR In \fIdeployment mode\fR, Bundler will \'roll\-out\' the bundle for production or CI use\. Please check carefully if you want to have this option enabled in your development environment\. . .IP This option is deprecated in favor of the \fBdeployment\fR setting\. . .TP \fB\-\-redownload\fR Force download every gem, even if the required versions are already available locally\. . .TP \fB\-\-frozen\fR Do not allow the Gemfile\.lock to be updated after this install\. Exits non\-zero if there are going to be changes to the Gemfile\.lock\. . .IP This option is deprecated in favor of the \fBfrozen\fR setting\. . .TP \fB\-\-full\-index\fR Bundler will not call Rubygems\' API endpoint (default) but download and cache a (currently big) index file of all gems\. Performance can be improved for large bundles that seldom change by enabling this option\. . .TP \fB\-\-gemfile=<gemfile>\fR The location of the Gemfile(5) which Bundler should use\. This defaults to a Gemfile(5) in the current working directory\. In general, Bundler will assume that the location of the Gemfile(5) is also the project\'s root and will try to find \fBGemfile\.lock\fR and \fBvendor/cache\fR relative to this location\. . .TP \fB\-\-jobs=[<number>]\fR, \fB\-j[<number>]\fR The maximum number of parallel download and install jobs\. The default is \fB1\fR\. . .TP \fB\-\-local\fR Do not attempt to connect to \fBrubygems\.org\fR\. Instead, Bundler will use the gems already present in Rubygems\' cache or in \fBvendor/cache\fR\. Note that if an appropriate platform\-specific gem exists on \fBrubygems\.org\fR it will not be found\. . .TP \fB\-\-no\-cache\fR Do not update the cache in \fBvendor/cache\fR with the newly bundled gems\. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install\. . .TP \fB\-\-no\-prune\fR Don\'t remove stale gems from the cache when the installation finishes\. . .IP This option is deprecated in favor of the \fBno_prune\fR setting\. . .TP \fB\-\-path=<path>\fR The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\. . .IP This option is deprecated in favor of the \fBpath\fR setting\. . .TP \fB\-\-quiet\fR Do not print progress information to the standard output\. Instead, Bundler will exit using a status code (\fB$?\fR)\. . .TP \fB\-\-retry=[<number>]\fR Retry failed network or git requests for \fInumber\fR times\. . .TP \fB\-\-shebang=<ruby\-executable>\fR Uses the specified ruby executable (usually \fBruby\fR) to execute the scripts created with \fB\-\-binstubs\fR\. In addition, if you use \fB\-\-binstubs\fR together with \fB\-\-shebang jruby\fR these executables will be changed to execute \fBjruby\fR instead\. . .IP This option is deprecated in favor of the \fBshebang\fR setting\. . .TP \fB\-\-standalone[=<list>]\fR Makes a bundle that can work without depending on Rubygems or Bundler at runtime\. A space separated list of groups to install has to be specified\. Bundler creates a directory named \fBbundle\fR and installs the bundle there\. It also generates a \fBbundle/bundler/setup\.rb\fR file to replace Bundler\'s own setup in the manner required\. Using this option implicitly sets \fBpath\fR, which is a [remembered option][REMEMBERED OPTIONS]\. . .TP \fB\-\-system\fR Installs the gems specified in the bundle to the system\'s Rubygems location\. This overrides any previous configuration of \fB\-\-path\fR\. . .IP This option is deprecated in favor of the \fBsystem\fR setting\. . .TP \fB\-\-trust\-policy=[<policy>]\fR Apply the Rubygems security policy \fIpolicy\fR, where policy is one of \fBHighSecurity\fR, \fBMediumSecurity\fR, \fBLowSecurity\fR, \fBAlmostNoSecurity\fR, or \fBNoSecurity\fR\. For more details, please see the Rubygems signing documentation linked below in \fISEE ALSO\fR\. . .TP \fB\-\-with=<list>\fR A space\-separated list of groups referencing gems to install\. If an optional group is given it is installed\. If a group is given that is in the remembered list of groups given to \-\-without, it is removed from that list\. . .IP This option is deprecated in favor of the \fBwith\fR setting\. . .TP \fB\-\-without=<list>\fR A space\-separated list of groups referencing gems to skip during installation\. If a group is given that is in the remembered list of groups given to \-\-with, it is removed from that list\. . .IP This option is deprecated in favor of the \fBwithout\fR setting\. . .SH "DEPLOYMENT MODE" Bundler\'s defaults are optimized for development\. To switch to defaults optimized for deployment and for CI, use the \fB\-\-deployment\fR flag\. Do not activate deployment mode on development machines, as it will cause an error when the Gemfile(5) is modified\. . .IP "1." 4 A \fBGemfile\.lock\fR is required\. . .IP To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a \fBGemfile\.lock\fR is required\. . .IP This is mainly to ensure that you remember to check your \fBGemfile\.lock\fR into version control\. . .IP "2." 4 The \fBGemfile\.lock\fR must be up to date . .IP In development, you can modify your Gemfile(5) and re\-run \fBbundle install\fR to \fIconservatively update\fR your \fBGemfile\.lock\fR snapshot\. . .IP In deployment, your \fBGemfile\.lock\fR should be up\-to\-date with changes made in your Gemfile(5)\. . .IP "3." 4 Gems are installed to \fBvendor/bundle\fR not your default system location . .IP In development, it\'s convenient to share the gems used in your application with other applications and other scripts that run on the system\. . .IP In deployment, isolation is a more important default\. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them\. . .IP As a result, \fBbundle install \-\-deployment\fR installs gems to the \fBvendor/bundle\fR directory in the application\. This may be overridden using the \fB\-\-path\fR option\. . .IP "" 0 . .SH "SUDO USAGE" By default, Bundler installs gems to the same location as \fBgem install\fR\. . .P In some cases, that location may not be writable by your Unix user\. In that case, Bundler will stage everything in a temporary directory, then ask you for your \fBsudo\fR password in order to copy the gems into their system location\. . .P From your perspective, this is identical to installing the gems directly into the system\. . .P You should never use \fBsudo bundle install\fR\. This is because several other steps in \fBbundle install\fR must be performed as the current user: . .IP "\(bu" 4 Updating your \fBGemfile\.lock\fR . .IP "\(bu" 4 Updating your \fBvendor/cache\fR, if necessary . .IP "\(bu" 4 Checking out private git repositories using your user\'s SSH keys . .IP "" 0 . .P Of these three, the first two could theoretically be performed by \fBchown\fRing the resulting files to \fB$SUDO_USER\fR\. The third, however, can only be performed by invoking the \fBgit\fR command as the current user\. Therefore, git gems are downloaded and installed into \fB~/\.bundle\fR rather than $GEM_HOME or $BUNDLE_PATH\. . .P As a result, you should run \fBbundle install\fR as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location\. . .SH "INSTALLING GROUPS" By default, \fBbundle install\fR will install all gems in all groups in your Gemfile(5), except those declared for a different platform\. . .P However, you can explicitly tell Bundler to skip installing certain groups with the \fB\-\-without\fR option\. This option takes a space\-separated list of groups\. . .P While the \fB\-\-without\fR option will skip \fIinstalling\fR the gems in the specified groups, it will still \fIdownload\fR those gems and use them to resolve the dependencies of every gem in your Gemfile(5)\. . .P This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against\. . .P \fBBundler offers a rock\-solid guarantee that the third\-party code you are running in development and testing is also the third\-party code you are running in production\. You can choose to exclude some of that code in different environments, but you will never be caught flat\-footed by different versions of third\-party code being used in different environments\.\fR . .P For a simple illustration, consider the following Gemfile(5): . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'sinatra\' group :production do gem \'rack\-perftools\-profiler\' end . .fi . .IP "" 0 . .P In this case, \fBsinatra\fR depends on any version of Rack (\fB>= 1\.0\fR), while \fBrack\-perftools\-profiler\fR depends on 1\.x (\fB~> 1\.0\fR)\. . .P When you run \fBbundle install \-\-without production\fR in development, we look at the dependencies of \fBrack\-perftools\-profiler\fR as well\. That way, you do not spend all your time developing against Rack 2\.0, using new APIs unavailable in Rack 1\.x, only to have Bundler switch to Rack 1\.2 when the \fBproduction\fR group \fIis\fR used\. . .P This should not cause any problems in practice, because we do not attempt to \fBinstall\fR the gems in the excluded groups, and only evaluate as part of the dependency resolution process\. . .P This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production\. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using\. . .SH "THE GEMFILE\.LOCK" When you run \fBbundle install\fR, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called \fBGemfile\.lock\fR\. . .P Bundler uses this file in all subsequent calls to \fBbundle install\fR, which guarantees that you always use the same exact code, even as your application moves across machines\. . .P Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point\-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies\. . .P As a result, you \fBSHOULD\fR check your \fBGemfile\.lock\fR into version control, in both applications and gems\. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third\-party code being used if \fBany\fR of the gems in the Gemfile(5) or any of their dependencies have been updated\. . .P When Bundler first shipped, the \fBGemfile\.lock\fR was included in the \fB\.gitignore\fR file included with generated gems\. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem\. Since \fBbundle install\fR is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing\. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems\. . .SH "CONSERVATIVE UPDATING" When you make a change to the Gemfile(5) and then run \fBbundle install\fR, Bundler will update only the gems that you modified\. . .P In other words, if a gem that you \fBdid not modify\fR worked before you called \fBbundle install\fR, it will continue to use the exact same versions of all dependencies as it used before the update\. . .P Let\'s take a look at an example\. Here\'s your original Gemfile(5): . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'actionpack\', \'2\.3\.8\' gem \'activemerchant\' . .fi . .IP "" 0 . .P In this case, both \fBactionpack\fR and \fBactivemerchant\fR depend on \fBactivesupport\fR\. The \fBactionpack\fR gem depends on \fBactivesupport 2\.3\.8\fR and \fBrack ~> 1\.1\.0\fR, while the \fBactivemerchant\fR gem depends on \fBactivesupport >= 2\.3\.2\fR, \fBbraintree >= 2\.0\.0\fR, and \fBbuilder >= 2\.0\.0\fR\. . .P When the dependencies are first resolved, Bundler will select \fBactivesupport 2\.3\.8\fR, which satisfies the requirements of both gems in your Gemfile(5)\. . .P Next, you modify your Gemfile(5) to: . .IP "" 4 . .nf source \'https://rubygems\.org\' gem \'actionpack\', \'3\.0\.0\.rc\' gem \'activemerchant\' . .fi . .IP "" 0 . .P The \fBactionpack 3\.0\.0\.rc\fR gem has a number of new dependencies, and updates the \fBactivesupport\fR dependency to \fB= 3\.0\.0\.rc\fR and the \fBrack\fR dependency to \fB~> 1\.2\.1\fR\. . .P When you run \fBbundle install\fR, Bundler notices that you changed the \fBactionpack\fR gem, but not the \fBactivemerchant\fR gem\. It evaluates the gems currently being used to satisfy its requirements: . .TP \fBactivesupport 2\.3\.8\fR also used to satisfy a dependency in \fBactivemerchant\fR, which is not being updated . .TP \fBrack ~> 1\.1\.0\fR not currently being used to satisfy another dependency . .P Because you did not explicitly ask to update \fBactivemerchant\fR, you would not expect it to suddenly stop working after updating \fBactionpack\fR\. However, satisfying the new \fBactivesupport 3\.0\.0\.rc\fR dependency of actionpack requires updating one of its dependencies\. . .P Even though \fBactivemerchant\fR declares a very loose dependency that theoretically matches \fBactivesupport 3\.0\.0\.rc\fR, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies\. In this case, the \fBactivemerchant\fR dependency is treated as \fBactivemerchant 1\.7\.1 + activesupport 2\.3\.8\fR, so \fBbundle install\fR will report that it cannot update \fBactionpack\fR\. . .P To explicitly update \fBactionpack\fR, including its dependencies which other gems in the Gemfile(5) still depend on, run \fBbundle update actionpack\fR (see \fBbundle update(1)\fR)\. . .P \fBSummary\fR: In general, after making a change to the Gemfile(5) , you should first try to run \fBbundle install\fR, which will guarantee that no other gem in the Gemfile(5) is impacted by the change\. If that does not work, run bundle update(1) \fIbundle\-update\.1\.html\fR\. . .SH "SEE ALSO" . .IP "\(bu" 4 Gem install docs \fIhttp://guides\.rubygems\.org/rubygems\-basics/#installing\-gems\fR . .IP "\(bu" 4 Rubygems signing docs \fIhttp://guides\.rubygems\.org/security/\fR . .IP "" 0 gems/gems/bundler-2.2.33/lib/bundler/man/gemfile.5 0000644 00000053300 15102661024 0015260 0 ustar 00 .\" generated with Ronn/v0.7.3 .\" http://github.com/rtomayko/ronn/tree/0.7.3 . .TH "GEMFILE" "5" "December 2021" "" "" . .SH "NAME" \fBGemfile\fR \- A format for describing gem dependencies for Ruby programs . .SH "SYNOPSIS" A \fBGemfile\fR describes the gem dependencies required to execute associated Ruby code\. . .P Place the \fBGemfile\fR in the root of the directory containing the associated code\.

This means that you cannot list different versions of the same gems in different groups\. For more details, see Understanding Bundler \fIhttps://bundler\.io/rationale\.html\fR\. . .SS "PLATFORMS" If a gem should only be used in a particular platform or set of platforms, you can specify them\. Platforms are essentially identical to groups, except that you do not need to use the \fB\-\-without\fR install\-time flag to exclude groups of gems for other platforms\. . .P There are a number of \fBGemfile\fR platforms: . .TP \fBruby\fR C Ruby (MRI), Rubinius or TruffleRuby, but \fBNOT\fR Windows . .TP \fBmri\fR Same as \fIruby\fR, but only C Ruby (MRI) . .TP \fBmingw\fR Windows 32 bit \'mingw32\' platform (aka RubyInstaller) . .TP \fBx64_mingw\fR Windows 64 bit \'mingw32\' platform (aka RubyInstaller x64) . .TP \fBrbx\fR Rubinius . .TP \fBjruby\fR JRuby . .TP \fBtruffleruby\fR TruffleRuby . .TP \fBmswin\fR Windows . .P You can restrict further by platform and version for all platforms \fIexcept\fR for \fBrbx\fR, \fBjruby\fR, \fBtruffleruby\fR and \fBmswin\fR\. . .P To specify a version in addition to a platform, append the version number without the delimiter to the platform\. For example, to specify that a gem should only be used on platforms with Ruby 2\.3, use: . .IP "" 4 . .nf ruby_23 . .fi . .IP "" 0 . .P The full list of platforms and supported versions includes: . .TP \fBruby\fR 1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6 . .TP \fBmri\fR 1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6 . .TP \fBmingw\fR 1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6 . .TP \fBx64_mingw\fR 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6 . .P As with groups, you can specify one or more platforms: . .IP "" 4 . .nf gem "weakling", :platforms => :jruby gem "ruby\-debug", :platforms => :mri_18 gem "nokogiri", :platforms => [:mri_18, :jruby] . .fi . .IP "" 0 . .P All operations involving groups (\fBbundle install\fR \fIbundle\-install\.1\.html\fR, \fBBundler\.setup\fR, \fBBundler\.require\fR) behave exactly the same as if any groups not matching the current platform were explicitly excluded\. . .SS "SOURCE" You can select an alternate Rubygems repository for a gem using the \':source\' option\. . .IP "" 4 . .nf gem "some_internal_gem", :source => "https://gems\.example\.com" . .fi . .IP "" 0 . .P This forces the gem to be loaded from this source and ignores any global sources declared at the top level of the file\. If the gem does not exist in this source, it will not be installed\. . .P Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on global sources using the ordering described in \fISOURCE PRIORITY\fR\. . .P Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in \fIGLOBAL SOURCES (#source)\fR\. . .P Using the \fB:source\fR option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources\. . .SS "GIT" If necessary, you can specify that a gem is located at a particular git repository using the \fB:git\fR parameter\. The repository can be accessed via several protocols: . .TP \fBHTTP(S)\fR gem "rails", :git => "https://github\.com/rails/rails\.git" . .TP \fBSSH\fR gem "rails", :git => "git@github\.com:rails/rails\.git" . .TP \fBgit\fR gem "rails", :git => "git://github\.com/rails/rails\.git" . .P If using SSH, the user that you use to run \fBbundle install\fR \fBMUST\fR have the appropriate keys available in their \fB$HOME/\.ssh\fR\. . .P \fBNOTE\fR: \fBhttp://\fR and \fBgit://\fR URLs should be avoided if at all possible\. These protocols are unauthenticated, so a man\-in\-the\-middle attacker can deliver malicious code and compromise your system\. HTTPS and SSH are strongly preferred\. . .P The \fBgroup\fR, \fBplatforms\fR, and \fBrequire\fR options are available and behave exactly the same as they would for a normal gem\. . .P A git repository \fBSHOULD\fR have at least one file, at the root of the directory containing the gem, with the extension \fB\.gemspec\fR\. This file \fBMUST\fR contain a valid gem specification, as expected by the \fBgem build\fR command\. . .P If a git repository does not have a \fB\.gemspec\fR, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions\. As a result, it may fail to properly integrate into your application\. . .P If a git repository does have a \fB\.gemspec\fR for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the \fB\.gemspec\fR specifies a version matching the version specifier\. If not, bundler will print a warning\. . .IP "" 4 . .nf gem "rails", "2\.3\.8", :git => "https://github\.com/rails/rails\.git" # bundle install will fail, because the \.gemspec in the rails # repository\'s master branch specifies version 3\.0\.0 . .fi . .IP "" 0 . .P If a git repository does \fBnot\fR have a \fB\.gemspec\fR for the gem you attached it to, a version specifier \fBMUST\fR be provided\. Bundler will use this version in the simple \fB\.gemspec\fR it creates\. . .P Git repositories support a number of additional options\. . .TP \fBbranch\fR, \fBtag\fR, and \fBref\fR You \fBMUST\fR only specify at most one of these options\. The default is \fB:branch => "master"\fR\. For example: . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :branch => "5\-0\-stable" . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :tag => "v5\.0\.0" . .IP gem "rails", :git => "https://github\.com/rails/rails\.git", :ref => "4aded" . .TP \fBsubmodules\fR For reference, a git submodule \fIhttps://git\-scm\.com/book/en/v2/Git\-Tools\-Submodules\fR lets you have another git repository within a subfolder of your repository\. Specify \fB:submodules => true\fR to cause bundler to expand any submodules included in the git repository . .P If a git repository contains multiple \fB\.gemspecs\fR, each \fB\.gemspec\fR represents a gem located at the same place in the file system as the \fB\.gemspec\fR\. . .IP "" 4 . .nf |~rails [git root] | |\-rails\.gemspec [rails gem located here] |~actionpack | |\-actionpack\.gemspec [actionpack gem located here] |~activesupport | |\-activesupport\.gemspec [activesupport gem located here] |\.\.\. . .fi . .IP "" 0 . .P To install a gem located in a git repository, bundler changes to the directory containing the gemspec, runs \fBgem build name\.gemspec\fR and then installs the resulting gem\. The \fBgem build\fR command, which comes standard with Rubygems, evaluates the \fB\.gemspec\fR in the context of the directory in which it is located\. . .SS "GIT SOURCE" A custom git source can be defined via the \fBgit_source\fR method\. Provide the source\'s name as an argument, and a block which receives a single argument and interpolates it into a string to return the full repo address: . .IP "" 4 . .nf git_source(:stash){ |repo_name| "https://stash\.corp\.acme\.pl/#{repo_name}\.git" } gem \'rails\', :stash => \'forks/rails\' . .fi . .IP "" 0 . .P In addition, if you wish to choose a specific branch: . .IP "" 4 . .nf gem "rails", :stash => "forks/rails", :branch => "branch_name" . .fi . .IP "" 0 . .SS "GITHUB" \fBNOTE\fR: This shorthand should be avoided until Bundler 2\.0, since it currently expands to an insecure \fBgit://\fR URL\. This allows a man\-in\-the\-middle attacker to compromise your system\. . .P If the git repository you want to use is hosted on GitHub and is public, you can use the :github shorthand to specify the github username and repository name (without the trailing "\.git"), separated by a slash\.

Relative paths are resolved relative to the directory containing the \fBGemfile\fR\. . .P Similar to the semantics of the \fB:git\fR option, the \fB:path\fR option requires that the directory in question either contains a \fB\.gemspec\fR for the gem, or that you specify an explicit version that bundler should use\. . .P Unlike \fB:git\fR, bundler does not compile C extensions for gems specified as paths\. . .IP "" 4 . .nf gem "rails", :path => "vendor/rails" . .fi . .IP "" 0 . .P If you would like to use multiple local gems directly from the filesystem, you can set a global \fBpath\fR option to the path containing the gem\'s files\.

Thus, when defining source blocks, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources, either via source blocks or \fB:source\fR directives on individual gems\. . .SH "INSTALL_IF" The \fBinstall_if\fR method allows gems to be installed based on a proc or lambda\.

Some required Gemspec attributes include the name, description, and homepage of your gem\. This is also where you specify the dependencies your gem needs to run\. . .P If you wish to use Bundler to help install dependencies for a gem while it is being developed, use the \fBgemspec\fR method to pull in the dependencies listed in the \fB\.gemspec\fR file\. . .P The \fBgemspec\fR method adds any runtime dependencies as gem requirements in the default group\. It also adds development dependencies as gem requirements in the \fBdevelopment\fR group\. Finally, it adds a gem requirement on your project (\fB:path => \'\.\'\fR)\. In conjunction with \fBBundler\.setup\fR, this allows you to require project files in your test code as you would if the project were installed as a gem; you need not manipulate the load path manually or require project files via relative paths\. . .P The \fBgemspec\fR method supports optional \fB:path\fR, \fB:glob\fR, \fB:name\fR, and \fB:development_group\fR options, which control where bundler looks for the \fB\.gemspec\fR, the glob it uses to look for the gemspec (defaults to: "{,\fI,\fR/*}\.gemspec"), what named \fB\.gemspec\fR it uses (if more than one is present), and which group development dependencies are included in\. . .P When a \fBgemspec\fR dependency encounters version conflicts during resolution, the local version under development will always be selected \-\- even if there are remote versions that better match other requirements for the \fBgemspec\fR gem\. . .SH "SOURCE PRIORITY" When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order: . .IP "1." 4 The source explicitly attached to the gem (using \fB:source\fR, \fB:path\fR, or \fB:git\fR) . .IP "2." 4 For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent\. This results in bundler prioritizing the ActiveSupport gem from the Rails git repository over ones from \fBrubygems\.org\fR . .IP "3." 4 The sources specified via global \fBsource\fR lines, searching each source in your \fBGemfile\fR from last added to first added\. . .IP "" 0 gems/gems/bundler-2.2.33/lib/bundler/man/bundle-config.1.ronn 0000644 00000045047 15102661024 0017344 0 ustar 00 bundle-config(1) -- Set bundler configuration options ===================================================== ## SYNOPSIS `bundle config` [list|get|set|unset] [<name> [<value>]] ## DESCRIPTION This command allows you to interact with Bundler's configuration system. Bundler loads configuration settings in this order: 1. Local config (`<project_root>/.bundle/config` or `$BUNDLE_APP_CONFIG/config`) 2. Environmental variables (`ENV`) 3. Global config (`~/.bundle/config`) 4. Bundler default config Executing `bundle config list` with will print a list of all bundler configuration for the current bundle, and where that configuration was set. Executing `bundle config get <name>` will print the value of that configuration setting, and where it was set. Executing `bundle config set <name> <value>` will set that configuration to the value specified for all bundles executed as the current user. The configuration will be stored in `~/.bundle/config`. If <name> already is set, <name> will be overridden and user will be warned. Executing `bundle config set --global <name> <value>` works the same as above. Executing `bundle config set --local <name> <value>` will set that configuration in the directory for the local application. The configuration will be stored in `<project_root>/.bundle/config`. If `BUNDLE_APP_CONFIG` is set, the configuration will be stored in `$BUNDLE_APP_CONFIG/config`. Executing `bundle config unset <name>` will delete the configuration in both local and global sources. Executing `bundle config unset --global <name>` will delete the configuration only from the user configuration. Executing `bundle config unset --local <name> <value>` will delete the configuration only from the local application. Executing bundle with the `BUNDLE_IGNORE_CONFIG` environment variable set will cause it to ignore all configuration. ## REMEMBERING OPTIONS Flags passed to `bundle install` or the Bundler runtime, such as `--path foo` or `--without production`, are remembered between commands and saved to your local application's configuration (normally, `./.bundle/config`). However, this will be changed in bundler 3, so it's better not to rely on this behavior. If these options must be remembered, it's better to set them using `bundle config` (e.g., `bundle config set --local path foo`). The options that can be configured are: * `bin`: Creates a directory (defaults to `~/bin`) and place any executables from the gem there. These executables run in Bundler's context. If used, you might add this directory to your environment's `PATH` variable. For instance, if the `rails` gem comes with a `rails` executable, this flag will create a `bin/rails` executable that ensures that all referred dependencies will be resolved using the bundled gems. * `deployment`: In deployment mode, Bundler will 'roll-out' the bundle for `production` use. Please check carefully if you want to have this option enabled in `development` or `test` environments. * `path`: The location to install the specified gems to. This defaults to Rubygems' setting. Bundler shares this location with Rubygems, `gem install ...` will have gem installed there, too. Therefore, gems installed without a `--path ...` setting will show up by calling `gem list`. Accordingly, gems installed to other locations will not get listed. * `without`: A space-separated list of groups referencing gems to skip during installation. * `with`: A space-separated list of groups referencing gems to include during installation. ## BUILD OPTIONS You can use `bundle config` to give Bundler the flags to pass to the gem installer every time bundler tries to install a particular gem. A very common example, the `mysql` gem, requires Snow Leopard users to pass configuration flags to `gem install` to specify where to find the `mysql_config` executable. gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config Since the specific location of that executable can change from machine to machine, you can specify these flags on a per-machine basis. bundle config set --global build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config After running this command, every time bundler needs to install the `mysql` gem, it will pass along the flags you specified. ## CONFIGURATION KEYS Configuration keys in bundler have two forms: the canonical form and the environment variable form. For instance, passing the `--without` flag to [bundle install(1)](bundle-install.1.html) prevents Bundler from installing certain groups specified in the Gemfile(5). Bundler persists this value in `app/.bundle/config` so that calls to `Bundler.setup` do not try to find gems from the `Gemfile` that you didn't install. Additionally, subsequent calls to [bundle install(1)](bundle-install.1.html) remember this setting and skip those groups. The canonical form of this configuration is `"without"`. To convert the canonical form to the environment variable form, capitalize it, and prepend `BUNDLE_`. The environment variable form of `"without"` is `BUNDLE_WITHOUT`. Any periods in the configuration keys must be replaced with two underscores when setting it via environment variables. The configuration key `local.rack` becomes the environment variable `BUNDLE_LOCAL__RACK`. ## LIST OF AVAILABLE KEYS The following is a list of all configuration keys and their purpose. You can learn more about their operation in [bundle install(1)](bundle-install.1.html). * `allow_deployment_source_credential_changes` (`BUNDLE_ALLOW_DEPLOYMENT_SOURCE_CREDENTIAL_CHANGES`): When in deployment mode, allow changing the credentials to a gem's source. Ex: `https://some.host.com/gems/path/` -> `https://user_name:password@some.host.com/gems/path` * `allow_offline_install` (`BUNDLE_ALLOW_OFFLINE_INSTALL`): Allow Bundler to use cached data when installing without network access. * `auto_clean_without_path` (`BUNDLE_AUTO_CLEAN_WITHOUT_PATH`): Automatically run `bundle clean` after installing when an explicit `path` has not been set and Bundler is not installing into the system gems. * `auto_install` (`BUNDLE_AUTO_INSTALL`): Automatically run `bundle install` when gems are missing. * `bin` (`BUNDLE_BIN`): Install executables from gems in the bundle to the specified directory. Defaults to `false`. * `cache_all` (`BUNDLE_CACHE_ALL`): Cache all gems, including path and git gems. This needs to be explicitly configured on bundler 1 and bundler 2, but will be the default on bundler 3. * `cache_all_platforms` (`BUNDLE_CACHE_ALL_PLATFORMS`): Cache gems for all platforms. * `cache_path` (`BUNDLE_CACHE_PATH`): The directory that bundler will place cached gems in when running <code>bundle package</code>, and that bundler will look in when installing gems. Defaults to `vendor/cache`. * `clean` (`BUNDLE_CLEAN`): Whether Bundler should run `bundle clean` automatically after `bundle install`. * `console` (`BUNDLE_CONSOLE`): The console that `bundle console` starts. Defaults to `irb`. * `default_install_uses_path` (`BUNDLE_DEFAULT_INSTALL_USES_PATH`): Whether a `bundle install` without an explicit `--path` argument defaults to installing gems in `.bundle`. * `deployment` (`BUNDLE_DEPLOYMENT`): Disallow changes to the `Gemfile`. When the `Gemfile` is changed and the lockfile has not been updated, running Bundler commands will be blocked. * `disable_checksum_validation` (`BUNDLE_DISABLE_CHECKSUM_VALIDATION`): Allow installing gems even if they do not match the checksum provided by RubyGems. * `disable_exec_load` (`BUNDLE_DISABLE_EXEC_LOAD`): Stop Bundler from using `load` to launch an executable in-process in `bundle exec`. * `disable_local_branch_check` (`BUNDLE_DISABLE_LOCAL_BRANCH_CHECK`): Allow Bundler to use a local git override without a branch specified in the Gemfile. * `disable_local_revision_check` (`BUNDLE_DISABLE_LOCAL_REVISION_CHECK`): Allow Bundler to use a local git override without checking if the revision present in the lockfile is present in the repository. * `disable_shared_gems` (`BUNDLE_DISABLE_SHARED_GEMS`): Stop Bundler from accessing gems installed to RubyGems' normal location. * `disable_version_check` (`BUNDLE_DISABLE_VERSION_CHECK`): Stop Bundler from checking if a newer Bundler version is available on rubygems.org. * `force_ruby_platform` (`BUNDLE_FORCE_RUBY_PLATFORM`): Ignore the current machine's platform and install only `ruby` platform gems. As a result, gems with native extensions will be compiled from source. * `frozen` (`BUNDLE_FROZEN`): Disallow changes to the `Gemfile`. When the `Gemfile` is changed and the lockfile has not been updated, running Bundler commands will be blocked. Defaults to `true` when `--deployment` is used. * `gem.github_username` (`BUNDLE_GEM__GITHUB_USERNAME`): Sets a GitHub username or organization to be used in `README` file when you create a new gem via `bundle gem` command. It can be overridden by passing an explicit `--github-username` flag to `bundle gem`. * `gem.push_key` (`BUNDLE_GEM__PUSH_KEY`): Sets the `--key` parameter for `gem push` when using the `rake release` command with a private gemstash server. * `gemfile` (`BUNDLE_GEMFILE`): The name of the file that bundler should use as the `Gemfile`. This location of this file also sets the root of the project, which is used to resolve relative paths in the `Gemfile`, among other things. By default, bundler will search up from the current working directory until it finds a `Gemfile`. * `global_gem_cache` (`BUNDLE_GLOBAL_GEM_CACHE`): Whether Bundler should cache all gems globally, rather than locally to the installing Ruby installation. * `ignore_messages` (`BUNDLE_IGNORE_MESSAGES`): When set, no post install messages will be printed. To silence a single gem, use dot notation like `ignore_messages.httparty true`. * `init_gems_rb` (`BUNDLE_INIT_GEMS_RB`): Generate a `gems.rb` instead of a `Gemfile` when running `bundle init`. * `jobs` (`BUNDLE_JOBS`): The number of gems Bundler can install in parallel. Defaults to 1 on Windows, and to the the number of processors on other platforms. * `no_install` (`BUNDLE_NO_INSTALL`): Whether `bundle package` should skip installing gems. * `no_prune` (`BUNDLE_NO_PRUNE`): Whether Bundler should leave outdated gems unpruned when caching. * `path` (`BUNDLE_PATH`): The location on disk where all gems in your bundle will be located regardless of `$GEM_HOME` or `$GEM_PATH` values. Bundle gems not found in this location will be installed by `bundle install`. Defaults to `Gem.dir`. When --deployment is used, defaults to vendor/bundle. * `path.system` (`BUNDLE_PATH__SYSTEM`): Whether Bundler will install gems into the default system path (`Gem.dir`). * `path_relative_to_cwd` (`BUNDLE_PATH_RELATIVE_TO_CWD`) Makes `--path` relative to the CWD instead of the `Gemfile`. * `plugins` (`BUNDLE_PLUGINS`): Enable Bundler's experimental plugin system. * `prefer_patch` (BUNDLE_PREFER_PATCH): Prefer updating only to next patch version during updates.

Defaults to `3`. * `setup_makes_kernel_gem_public` (`BUNDLE_SETUP_MAKES_KERNEL_GEM_PUBLIC`): Have `Bundler.setup` make the `Kernel#gem` method public, even though RubyGems declares it as private. * `shebang` (`BUNDLE_SHEBANG`): The program name that should be invoked for generated binstubs. Defaults to the ruby install name used to generate the binstub. * `silence_deprecations` (`BUNDLE_SILENCE_DEPRECATIONS`): Whether Bundler should silence deprecation warnings for behavior that will be changed in the next major version. * `silence_root_warning` (`BUNDLE_SILENCE_ROOT_WARNING`): Silence the warning Bundler prints when installing gems as root. * `ssl_ca_cert` (`BUNDLE_SSL_CA_CERT`): Path to a designated CA certificate file or folder containing multiple certificates for trusted CAs in PEM format. * `ssl_client_cert` (`BUNDLE_SSL_CLIENT_CERT`): Path to a designated file containing a X.509 client certificate and key in PEM format. * `ssl_verify_mode` (`BUNDLE_SSL_VERIFY_MODE`): The SSL verification mode Bundler uses when making HTTPS requests. Defaults to verify peer. * `suppress_install_using_messages` (`BUNDLE_SUPPRESS_INSTALL_USING_MESSAGES`): Avoid printing `Using ...` messages during installation when the version of a gem has not changed. * `system_bindir` (`BUNDLE_SYSTEM_BINDIR`): The location where RubyGems installs binstubs. Defaults to `Gem.bindir`. * `timeout` (`BUNDLE_TIMEOUT`): The seconds allowed before timing out for network requests. Defaults to `10`. * `update_requires_all_flag` (`BUNDLE_UPDATE_REQUIRES_ALL_FLAG`): Require passing `--all` to `bundle update` when everything should be updated, and disallow passing no options to `bundle update`. * `user_agent` (`BUNDLE_USER_AGENT`): The custom user agent fragment Bundler includes in API requests. * `with` (`BUNDLE_WITH`): A `:`-separated list of groups whose gems bundler should install. * `without` (`BUNDLE_WITHOUT`): A `:`-separated list of groups whose gems bundler should not install. In general, you should set these settings per-application by using the applicable flag to the [bundle install(1)](bundle-install.1.html) or [bundle package(1)](bundle-package.1.html) command. You can set them globally either via environment variables or `bundle config`, whichever is preferable for your setup. If you use both, environment variables will take preference over global settings. ## LOCAL GIT REPOS Bundler also allows you to work against a git repository locally instead of using the remote version. This can be achieved by setting up a local override: bundle config set --local local.GEM_NAME /path/to/local/git/repository For example, in order to use a local Rack repository, a developer could call: bundle config set --local local.rack ~/Work/git/rack Now instead of checking out the remote git repository, the local override will be used. Similar to a path source, every time the local git repository change, changes will be automatically picked up by Bundler. This means a commit in the local git repo will update the revision in the `Gemfile.lock` to the local git repo revision. This requires the same attention as git submodules. Before pushing to the remote, you need to ensure the local override was pushed, otherwise you may point to a commit that only exists in your local machine. You'll also need to CGI escape your usernames and passwords as well. Bundler does many checks to ensure a developer won't work with invalid references. Particularly, we force a developer to specify a branch in the `Gemfile` in order to use this feature. If the branch specified in the `Gemfile` and the current branch in the local git repository do not match, Bundler will abort. This ensures that a developer is always working against the correct branches, and prevents accidental locking to a different branch. Finally, Bundler also ensures that the current revision in the `Gemfile.lock` exists in the local git repository. By doing this, Bundler forces you to fetch the latest changes in the remotes. ## MIRRORS OF GEM SOURCES Bundler supports overriding gem sources with mirrors. This allows you to configure rubygems.org as the gem source in your Gemfile while still using your mirror to fetch gems. bundle config set --global mirror.SOURCE_URL MIRROR_URL For example, to use a mirror of rubygems.org hosted at rubygems-mirror.org: bundle config set --global mirror.http://rubygems.org http://rubygems-mirror.org Each mirror also provides a fallback timeout setting. If the mirror does not respond within the fallback timeout, Bundler will try to use the original server instead of the mirror. bundle config set --global mirror.SOURCE_URL.fallback_timeout TIMEOUT For example, to fall back to rubygems.org after 3 seconds: bundle config set --global mirror.https://rubygems.org.fallback_timeout 3 The default fallback timeout is 0.1 seconds, but the setting can currently only accept whole seconds (for example, 1, 15, or 30). ## CREDENTIALS FOR GEM SOURCES Bundler allows you to configure credentials for any gem source, which allows you to avoid putting secrets into your Gemfile. bundle config set --global SOURCE_HOSTNAME USERNAME:PASSWORD For example, to save the credentials of user `claudette` for the gem source at `gems.longerous.com`, you would run: bundle config set --global gems.longerous.com claudette:s00pers3krit Or you can set the credentials as an environment variable like this: export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit" For gems with a git source with HTTP(S) URL you can specify credentials like so: bundle config set --global https://github.com/rubygems/rubygems.git username:password Or you can set the credentials as an environment variable like so: export BUNDLE_GITHUB__COM=username:password This is especially useful for private repositories on hosts such as Github, where you can use personal OAuth tokens: export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x-oauth-basic Note that any configured credentials will be redacted by informative commands such as `bundle config list` or `bundle config get`, unless you use the `--parseable` flag. This is to avoid unintentionally leaking credentials when copy-pasting bundler output. Also note that to guarantee a sane mapping between valid environment variable names and valid host names, bundler makes the following transformations: * Any `-` characters in a host name are mapped to a triple dash (`___`) in the corresponding environment variable. * Any `.` characters in a host name are mapped to a double dash (`__`) in the corresponding environment variable. This means that if you have a gem server named `my.gem-host.com`, you'll need to use the `BUNDLE_MY__GEM___HOST__COM` variable to configure credentials for it through ENV. ## CONFIGURE BUNDLER DIRECTORIES Bundler's home, config, cache and plugin directories are able to be configured through environment variables. The default location for Bundler's home directory is `~/.bundle`, which all directories inherit from by default. The following outlines the available environment variables and their default values BUNDLE_USER_HOME : $HOME/.bundle BUNDLE_USER_CACHE : $BUNDLE_USER_HOME/cache BUNDLE_USER_CONFIG : $BUNDLE_USER_HOME/config BUNDLE_USER_PLUGIN : $BUNDLE_USER_HOME/plugin gems/gems/bundler-2.2.33/lib/bundler/man/bundle-info.1.ronn 0000644 00000000561 15102661024 0017022 0 ustar 00 bundle-info(1) -- Show information for the given gem in your bundle ========================================================================= ## SYNOPSIS `bundle info` [GEM] [--path] ## DESCRIPTION Print the basic information about the provided GEM such as homepage, version, path and summary. ## OPTIONS * `--path`: Print the path of the given gem gems/gems/bundler-2.2.33/lib/bundler/man/bundle-cache.1.ronn 0000644 00000005577 15102661024 0017146 0 ustar 00 bundle-cache(1) -- Package your needed `.gem` files into your application =========================================================================== ## SYNOPSIS `bundle cache` ## DESCRIPTION Copy all of the `.gem` files needed to run the application into the `vendor/cache` directory. In the future, when running [bundle install(1)][bundle-install], use the gems in the cache in preference to the ones on `rubygems.org`. ## GIT AND PATH GEMS The `bundle cache` command can also package `:git` and `:path` dependencies besides .gem files. This needs to be explicitly enabled via the `--all` option. Once used, the `--all` option will be remembered. ## SUPPORT FOR MULTIPLE PLATFORMS When using gems that have different packages for different platforms, Bundler supports caching of gems for other platforms where the Gemfile has been resolved (i.e. present in the lockfile) in `vendor/cache`. This needs to be enabled via the `--all-platforms` option. This setting will be remembered in your local bundler configuration. ## REMOTE FETCHING By default, if you run `bundle install(1)`](bundle-install.1.html) after running [bundle cache(1)](bundle-cache.1.html), bundler will still connect to `rubygems.org` to check whether a platform-specific gem exists for any of the gems in `vendor/cache`. For instance, consider this Gemfile(5): source "https://rubygems.org" gem "nokogiri" If you run `bundle cache` under C Ruby, bundler will retrieve the version of `nokogiri` for the `"ruby"` platform. If you deploy to JRuby and run `bundle install`, bundler is forced to check to see whether a `"java"` platformed `nokogiri` exists. Even though the `nokogiri` gem for the Ruby platform is _technically_ acceptable on JRuby, it has a C extension that does not run on JRuby. As a result, bundler will, by default, still connect to `rubygems.org` to check whether it has a version of one of your gems more specific to your platform. This problem is also not limited to the `"java"` platform. A similar (common) problem can happen when developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux. If you know for sure that the gems packaged in `vendor/cache` are appropriate for the platform you are on, you can run `bundle install --local` to skip checking for more appropriate gems, and use the ones in `vendor/cache`. One way to be sure that you have the right platformed versions of all your gems is to run `bundle cache` on an identical machine and check in the gems. For instance, you can run `bundle cache` on an identical staging box during your staging process, and check in the `vendor/cache` before deploying to production. By default, [bundle cache(1)](bundle-cache.1.html) fetches and also installs the gems to the default location. To package the dependencies to `vendor/cache` without installing them to the local install location, you can run `bundle cache --no-install`. gems/gems/bundler-2.2.33/lib/bundler/man/bundle-show.1.ronn 0000644 00000001124 15102661024 0017043 0 ustar 00 bundle-show(1) -- Shows all the gems in your bundle, or the path to a gem ========================================================================= ## SYNOPSIS `bundle show` [GEM] [--paths] ## DESCRIPTION Without the [GEM] option, `show` will print a list of the names and versions of all gems that are required by your [`Gemfile(5)`][Gemfile(5)], sorted by name.

Here, we're treating each key in # the hash as a node in the graph, and so we simply alias the required # #tsort_each_node method to Hash's #each_key method. For each key in the # hash, the associated value is an array of the node's child nodes. This # choice in turn leads to our implementation of the required #tsort_each_child # method, which fetches the array of child nodes and then iterates over that # array using the user-supplied block. # # require 'tsort' # # class Hash # include TSort # alias tsort_each_node each_key # def tsort_each_child(node, &block) # fetch(node).each(&block) # end # end # # {1=>[2, 3], 2=>[3], 3=>[], 4=>[]}.tsort # #=> [3, 2, 1, 4] # # {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components # #=> [[4], [2, 3], [1]] # # == A More Realistic Example # # A very simple `make' like tool can be implemented as follows: # # require 'tsort' # # class Make # def initialize # @dep = {} # @dep.default = [] # end # # def rule(outputs, inputs=[], &block) # triple = [outputs, inputs, block] # outputs.each {|f| @dep[f] = [triple]} # @dep[triple] = inputs # end # # def build(target) # each_strongly_connected_component_from(target) {|ns| # if ns.length != 1 # fs = ns.delete_if {|n| Array === n} # raise TSort::Cyclic.new("cyclic dependencies: #{fs.join ', '}") # end # n = ns.first # if Array === n # outputs, inputs, block = n # inputs_time = inputs.map {|f| File.mtime f}.max # begin # outputs_time = outputs.map {|f| File.mtime f}.min # rescue Errno::ENOENT # outputs_time = nil # end # if outputs_time == nil || # inputs_time != nil && outputs_time <= inputs_time # sleep 1 if inputs_time != nil && inputs_time.to_i == Time.now.to_i # block.call # end # end # } # end # # def tsort_each_child(node, &block) # @dep[node].each(&block) # end # include TSort # end # # def command(arg) # print arg, "\n" # system arg # end # # m = Make.new # m.rule(%w[t1]) { command 'date > t1' } # m.rule(%w[t2]) { command 'date > t2' } # m.rule(%w[t3]) { command 'date > t3' } # m.rule(%w[t4], %w[t1 t3]) { command 'cat t1 t3 > t4' } # m.rule(%w[t5], %w[t4 t2]) { command 'cat t4 t2 > t5' } # m.build('t5') # # == Bugs # # * 'tsort.rb' is wrong name because this library uses # Tarjan's algorithm for strongly connected components. # Although 'strongly_connected_components.rb' is correct but too long. # # == References # # R.

For each host:port you communicate with a # single persistent connection is created. # # Connections will be shared across threads through a connection pool to # increase reuse of connections. # # You can shut down any remaining HTTP connections when done by calling # #shutdown. # # Example: # # require 'bundler/vendor/net-http-persistent/lib/net/http/persistent' # # uri = Bundler::URI 'http://example.com/awesome/web/service' # # http = Bundler::Persistent::Net::HTTP::Persistent.new # # # perform a GET # response = http.request uri # # # or # # get = Net::HTTP::Get.new uri.request_uri # response = http.request get # # # create a POST # post_uri = uri + 'create' # post = Net::HTTP::Post.new post_uri.path # post.set_form_data 'some' => 'cool data' # # # perform the POST, the Bundler::URI is always required # response http.request post_uri, post # # Note that for GET, HEAD and other requests that do not have a body you want # to use Bundler::URI#request_uri not Bundler::URI#path. The request_uri contains the query # params which are sent in the body for other requests. # # == TLS/SSL # # TLS connections are automatically created depending upon the scheme of the # Bundler::URI. TLS connections are automatically verified against the default # certificate store for your computer. You can override this by changing # verify_mode or by specifying an alternate cert_store. # # Here are the TLS settings, see the individual methods for documentation: # # #certificate :: This client's certificate # #ca_file :: The certificate-authorities # #ca_path :: Directory with certificate-authorities # #cert_store :: An SSL certificate store # #ciphers :: List of SSl ciphers allowed # #private_key :: The client's SSL private key # #reuse_ssl_sessions :: Reuse a previously opened SSL session for a new # connection # #ssl_timeout :: Session lifetime # #ssl_version :: Which specific SSL version to use # #verify_callback :: For server certificate verification # #verify_depth :: Depth of certificate verification # #verify_mode :: How connections should be verified # # == Proxies # # A proxy can be set through #proxy= or at initialization time by providing a # second argument to ::new. The proxy may be the Bundler::URI of the proxy server or # <code>:ENV</code> which will consult environment variables. # # See #proxy= and #proxy_from_env for details. # # == Headers # # Headers may be specified for use in every request. #headers are appended to # any headers on the request. #override_headers replace existing headers on # the request. # # The difference between the two can be seen in setting the User-Agent. Using # <code>http.headers['User-Agent'] = 'MyUserAgent'</code> will send "Ruby, # MyUserAgent" while <code>http.override_headers['User-Agent'] = # 'MyUserAgent'</code> will send "MyUserAgent". # # == Tuning # # === Segregation # # Each Bundler::Persistent::Net::HTTP::Persistent instance has its own pool of connections. There # is no sharing with other instances (as was true in earlier versions). # # === Idle Timeout # # If a connection hasn't been used for this number of seconds it will # automatically be reset upon the next use to avoid attempting to send to a # closed connection. The default value is 5 seconds. nil means no timeout. # Set through #idle_timeout. # # Reducing this value may help avoid the "too many connection resets" error # when sending non-idempotent requests while increasing this value will cause # fewer round-trips. # # === Read Timeout # # The amount of time allowed between reading two chunks from the socket. Set # through #read_timeout # # === Max Requests # # The number of requests that should be made before opening a new connection. # Typically many keep-alive capable servers tune this to 100 or less, so the # 101st request will fail with ECONNRESET. If unset (default), this value has # no effect, if set, connections will be reset on the request after # max_requests. # # === Open Timeout # # The amount of time to wait for a connection to be opened. Set through # #open_timeout. # # === Socket Options # # Socket options may be set on newly-created connections. See #socket_options # for details. # # === Connection Termination # # If you are done using the Bundler::Persistent::Net::HTTP::Persistent instance you may shut down # all the connections in the current thread with #shutdown. This is not # recommended for normal use, it should only be used when it will be several # minutes before you make another HTTP request. # # If you are using multiple threads, call #shutdown in each thread when the # thread is done making requests. If you don't call shutdown, that's OK. # Ruby will automatically garbage collect and shutdown your HTTP connections # when the thread terminates. class Bundler::Persistent::Net::HTTP::Persistent ## # The beginning of Time EPOCH = Time.at 0 # :nodoc: ## # Is OpenSSL available?

We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community. ## Our Standards Examples of behavior that contributes to a positive environment for our community include: * Demonstrating empathy and kindness toward other people * Being respectful of differing opinions, viewpoints, and experiences * Giving and gracefully accepting constructive feedback * Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience * Focusing on what is best not just for us as individuals, but for the overall community Examples of unacceptable behavior include: * The use of sexualized language or imagery, and sexual attention or advances of any kind * Trolling, insulting or derogatory comments, and personal or political attacks * Public or private harassment * Publishing others' private information, such as a physical or email address, without their explicit permission * Other conduct which could reasonably be considered inappropriate in a professional setting ## Enforcement Responsibilities Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful. Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate. ## Scope This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. ## Enforcement Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at <%= config[:email] %>. All complaints will be reviewed and investigated promptly and fairly. All community leaders are obligated to respect the privacy and security of the reporter of any incident. ## Enforcement Guidelines Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct: ### 1. Correction **Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community. **Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested. ### 2. Warning **Community Impact**: A violation through a single incident or series of actions. **Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban. ### 3. Temporary Ban **Community Impact**: A serious violation of community standards, including sustained inappropriate behavior. **Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban. ### 4. Permanent Ban **Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. **Consequence**: A permanent ban from any sort of public interaction within the community. ## Attribution This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 2.0, available at https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. Community Impact Guidelines were inspired by [Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity).

Some of these parts are high-level: paragraphs, # chunks of verbatim text, list entries and the like. Other parts happen at # the character level: a piece of bold text, a word in code font. This markup # is similar in spirit to that used on WikiWiki webs, where folks create web # pages using a simple set of formatting rules. # # RDoc::Markup and other markup formats do no output formatting, this is # handled by the RDoc::Markup::Formatter subclasses. # # = Supported Formats # # Besides the RDoc::Markup format, the following formats are built in to RDoc: # # markdown:: # The markdown format as described by # http://daringfireball.net/projects/markdown/. See RDoc::Markdown for # details on the parser and supported extensions. # rd:: # The rdtool format. See RDoc::RD for details on the parser and format. # tomdoc:: # The TomDoc format as described by http://tomdoc.org/. See RDoc::TomDoc # for details on the parser and supported extensions. # # You can choose a markup format using the following methods: # # per project:: # If you build your documentation with rake use RDoc::Task#markup. # # If you build your documentation by hand run: # # rdoc --markup your_favorite_format --write-options # # and commit <tt>.rdoc_options</tt> and ship it with your packaged gem. # per file:: # At the top of the file use the <tt>:markup:</tt> directive to set the # default format for the rest of the file. # per comment:: # Use the <tt>:markup:</tt> directive at the top of a comment you want # to write in a different format. # # = RDoc::Markup # # RDoc::Markup is extensible at runtime: you can add \new markup elements to # be recognized in the documents that RDoc::Markup parses. # # RDoc::Markup is intended to be the basis for a family of tools which share # the common requirement that simple, plain-text should be rendered in a # variety of different output formats and media. It is envisaged that # RDoc::Markup could be the basis for formatting RDoc style comment blocks, # Wiki entries, and online FAQs. # # == Synopsis # # This code converts +input_string+ to HTML. The conversion takes place in # the +convert+ method, so you can use the same RDoc::Markup converter to # convert multiple input strings. # # require 'rdoc' # # h = RDoc::Markup::ToHtml.new(RDoc::Options.new) # # puts h.convert(input_string) # # You can extend the RDoc::Markup parser to recognize new markup # sequences, and to add regexp handling. Here we make WikiWords significant to # the parser, and also make the sequences {word} and \<no>text...</no> signify # strike-through text. We then subclass the HTML output class to deal # with these: # # require 'rdoc' # # class WikiHtml < RDoc::Markup::ToHtml # def handle_regexp_WIKIWORD(target) # "<font color=red>" + target.text + "</font>" # end # end # # markup = RDoc::Markup.new # markup.add_word_pair("{", "}", :STRIKE) # markup.add_html("no", :STRIKE) # # markup.add_regexp_handling(/\b([A-Z][a-z]+[A-Z]\w+)/, :WIKIWORD) # # wh = WikiHtml.new RDoc::Options.new, markup # wh.add_tag(:STRIKE, "<strike>", "</strike>") # # puts "<body>#{wh.convert ARGF.read}</body>" # # == Encoding # # Where Encoding support is available, RDoc will automatically convert all # documents to the same output encoding. The output encoding can be set via # RDoc::Options#encoding and defaults to Encoding.default_external. # # = \RDoc Markup Reference # # == Block Markup # # === Paragraphs and Verbatim # # The markup engine looks for a document's natural left margin. This is # used as the initial margin for the document. # # Consecutive lines starting at this margin are considered to be a # paragraph. Empty lines separate paragraphs. # # Any line that starts to the right of the current margin is treated # as verbatim text. This is useful for code listings: # # 3.times { puts "Ruby" } # # In verbatim text, two or more blank lines are collapsed into one, # and trailing blank lines are removed: # # This is the first line # # # This is the second non-blank line, # after 2 blank lines in the source markup. # # # There were two trailing blank lines right above this paragraph, that # have been removed. In addition, the verbatim text has been shifted # left, so the amount of indentation of verbatim text is unimportant. # # For HTML output RDoc makes a small effort to determine if a verbatim section # contains Ruby source code. If so, the verbatim block will be marked up as # HTML. Triggers include "def", "class", "module", "require", the "hash # rocket"# (=>) or a block call with a parameter. # # === Headers # # A line starting with an equal sign (=) is treated as a # heading. Level one headings have one equals sign, level two headings # have two, and so on until level six, which is the maximum # (seven hyphens or more result in a level six heading). # # For example, the above header was obtained with: # # === Headers # # In HTML output headers have an id matching their name. The above example's # HTML is: # # <h3 id="label-Headers">Headers</h3> # # If a heading is inside a method body the id will be prefixed with the # method's id. If the above header where in the documentation for a method # such as: # # ## # # This method does fun things # # # # = Example # # # # Example of fun things goes here ... # # def do_fun_things # end # # The header's id would be: # # <h1 id="method-i-do_fun_things-label-Example">Example</h1> # # The label can be linked-to using <tt>SomeClass@Headers</tt>. See # {Links}[RDoc::Markup@Links] for further details. # # === Rules # # A line starting with three or more hyphens (at the current indent) # generates a horizontal rule. # # --- # # produces: # # --- # # === Simple Lists # # If a paragraph starts with a "*", "-", "<digit>." or "<letter>.", # then it is taken to be the start of a list. The margin is increased to be # the first non-space following the list start flag. Subsequent lines # should be indented to this new margin until the list ends. For example: # # * this is a list with three paragraphs in # the first item. This is the first paragraph. # # And this is the second paragraph. # # 1. This is an indented, numbered list. # 2. This is the second item in that list # # This is the third conventional paragraph in the # first list item. # # * This is the second item in the original list # # produces: # # * this is a list with three paragraphs in # the first item. This is the first paragraph. # # And this is the second paragraph. # # 1. This is an indented, numbered list. # 2. This is the second item in that list # # This is the third conventional paragraph in the # first list item. # # * This is the second item in the original list # # === Labeled Lists # # You can also construct labeled lists, sometimes called description # or definition lists. Do this by putting the label in square brackets # and indenting the list body: # # [cat] a small furry mammal # that seems to sleep a lot # # [ant] a little insect that is known # to enjoy picnics # # produces: # # [cat] a small furry mammal # that seems to sleep a lot # # [ant] a little insect that is known # to enjoy picnics # # If you want the list bodies to line up to the left of the labels, # use two colons: # # cat:: a small furry mammal # that seems to sleep a lot # # ant:: a little insect that is known # to enjoy picnics # # produces: # # cat:: a small furry mammal # that seems to sleep a lot # # ant:: a little insect that is known # to enjoy picnics # # Notice that blank lines right after the label are ignored in labeled lists: # # [one] # # definition 1 # # [two] # # definition 2 # # produces the same output as # # [one] definition 1 # [two] definition 2 # # # === Lists and Verbatim # # If you want to introduce a verbatim section right after a list, it has to be # less indented than the list item bodies, but more indented than the list # label, letter, digit or bullet. For instance: # # * point 1 # # * point 2, first paragraph # # point 2, second paragraph # verbatim text inside point 2 # point 2, third paragraph # verbatim text outside of the list (the list is therefore closed) # regular paragraph after the list # # produces: # # * point 1 # # * point 2, first paragraph # # point 2, second paragraph # verbatim text inside point 2 # point 2, third paragraph # verbatim text outside of the list (the list is therefore closed) # regular paragraph after the list # # == Text Markup # # === Bold, Italic, Typewriter Text # # You can use markup within text (except verbatim) to change the # appearance of parts of that text. Out of the box, RDoc::Markup # supports word-based and general markup. # # Word-based markup uses flag characters around individual words: # # <tt>\*_word_\*</tt>:: displays _word_ in a *bold* font # <tt>\__word_\_</tt>:: displays _word_ in an _emphasized_ font # <tt>\+_word_\+</tt>:: displays _word_ in a +code+ font # # General markup affects text between a start delimiter and an end # delimiter. Not surprisingly, these delimiters look like HTML markup. # # <tt>\<b>_text_</b></tt>:: displays _text_ in a *bold* font # <tt>\<em>_text_</em></tt>:: displays _text_ in an _emphasized_ font # (alternate tag: <tt>\<i></tt>) # <tt>\<tt>_text_\</tt></tt>:: displays _text_ in a +code+ font # (alternate tag: <tt>\<code></tt>) # # Unlike conventional Wiki markup, general markup can cross line # boundaries. You can turn off the interpretation of markup by # preceding the first character with a backslash (see <i>Escaping # Text Markup</i>, below). # # === Links # # Links to starting with +http:+, +https:+, +mailto:+, +ftp:+ or +www.+ # are recognized. An HTTP url that references an external image is converted # into an inline image element. # # Classes and methods will be automatically linked to their definition. For # example, <tt>RDoc::Markup</tt> will link to this documentation. By default # methods will only be automatically linked if they contain an <tt>_</tt> (all # methods can be automatically linked through the <tt>--hyperlink-all</tt> # command line option). # # Single-word methods can be linked by using the <tt>#</tt> character for # instance methods or <tt>::</tt> for class methods. For example, # <tt>#convert</tt> links to #convert. A class or method may be combined like # <tt>RDoc::Markup#convert</tt>. # # A heading inside the documentation can be linked by following the class # or method by an <tt>@</tt> then the heading name. # <tt>RDoc::Markup@Links</tt> will link to this section like this: # RDoc::Markup@Links. Spaces in headings with multiple words must be escaped # with <tt>+</tt> like <tt>RDoc::Markup@Escaping+Text+Markup</tt>. # Punctuation and other special characters must be escaped like CGI.escape. # # The <tt>@</tt> can also be used to link to sections. If a section and a # heading share the same name the section is preferred for the link. # # Links can also be of the form <tt>label[url]</tt>, in which case +label+ is # used in the displayed text, and +url+ is used as the target. If +label+ # contains multiple words, put it in braces: <tt>{multi word label}[url]</tt>. # The +url+ may be an +http:+-type link or a cross-reference to a class, # module or method with a label. # # Links with the <code>rdoc-image:</code> scheme will create an image tag for # HTML output. Only fully-qualified URLs are supported. # # Links with the <tt>rdoc-ref:</tt> scheme will link to the referenced class, # module, method, file, etc. If the referenced item is does not exist # no link will be generated and <tt>rdoc-ref:</tt> will be removed from the # resulting text. # # Links starting with <tt>rdoc-label:label_name</tt> will link to the # +label_name+. You can create a label for the current link (for # bidirectional links) by supplying a name for the current link like # <tt>rdoc-label:label-other:label-mine</tt>. # # Links starting with +link:+ refer to local files whose path is relative to # the <tt>--op</tt> directory. Use <tt>rdoc-ref:</tt> instead of # <tt>link:</tt> to link to files generated by RDoc as the link target may # be different across RDoc generators. # # Example links: # # https://github.com/ruby/rdoc # mailto:user@example.com # {RDoc Documentation}[http://rdoc.rubyforge.org] # {RDoc Markup}[rdoc-ref:RDoc::Markup] # # === Escaping Text Markup # # Text markup can be escaped with a backslash, as in \<tt>, which was obtained # with <tt>\\<tt></tt>. Except in verbatim sections and between \<tt> tags, # to produce a backslash you have to double it unless it is followed by a # space, tab or newline. Otherwise, the HTML formatter will discard it, as it # is used to escape potential links: # # * The \ must be doubled if not followed by white space: \\. # * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space. # * This is a link to {ruby-lang}[www.ruby-lang.org]. # * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org]. # * This will not be linked to \RDoc::RDoc#document # # generates: # # * The \ must be doubled if not followed by white space: \\. # * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space. # * This is a link to {ruby-lang}[www.ruby-lang.org] # * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org] # * This will not be linked to \RDoc::RDoc#document # # Inside \<tt> tags, more precisely, leading backslashes are removed only if # followed by a markup character (<tt><*_+</tt>), a backslash, or a known link # reference (a known class or method). So in the example above, the backslash # of <tt>\S</tt> would be removed if there was a class or module named +S+ in # the current context. # # This behavior is inherited from RDoc version 1, and has been kept for # compatibility with existing RDoc documentation. # # === Conversion of characters # # HTML will convert two/three dashes to an em-dash. Other common characters are # converted as well: # # em-dash:: -- or --- # ellipsis:: ... # # single quotes:: 'text' or `text' # double quotes:: "text" or ``text'' # # copyright:: (c) # registered trademark:: (r) # # produces: # # em-dash:: -- or --- # ellipsis:: ... # # single quotes:: 'text' or `text' # double quotes:: "text" or ``text'' # # copyright:: (c) # registered trademark:: (r) # # # == Documenting Source Code # # Comment blocks can be written fairly naturally, either using <tt>#</tt> on # successive lines of the comment, or by including the comment in # a <tt>=begin</tt>/<tt>=end</tt> block. If you use the latter form, # the <tt>=begin</tt> line _must_ be flagged with an +rdoc+ tag: # # =begin rdoc # Documentation to be processed by RDoc. # # ... # =end # # RDoc stops processing comments if it finds a comment line starting # with <tt>--</tt> right after the <tt>#</tt> character (otherwise, # it will be treated as a rule if it has three dashes or more). # This can be used to separate external from internal comments, # or to stop a comment being associated with a method, class, or module. # Commenting can be turned back on with a line that starts with <tt>++</tt>. # # ## # # Extract the age and calculate the date-of-birth. # #-- # # FIXME: fails if the birthday falls on February 29th # #++ # # The DOB is returned as a Time object. # # def get_dob(person) # # ... # end # # Names of classes, files, and any method names containing an underscore or # preceded by a hash character are automatically linked from comment text to # their description. This linking works inside the current class or module, # and with ancestor methods (in included modules or in the superclass). # # Method parameter lists are extracted and displayed with the method # description. If a method calls +yield+, then the parameters passed to yield # will also be displayed: # # def fred # ... # yield line, address # # This will get documented as: # # fred() { |line, address| ... } # # You can override this using a comment containing ':yields: ...' immediately # after the method definition # # def fred # :yields: index, position # # ... # # yield line, address # # which will get documented as # # fred() { |index, position| ... } # # +:yields:+ is an example of a documentation directive. These appear # immediately after the start of the document element they are modifying. # # RDoc automatically cross-references words with underscores or camel-case. # To suppress cross-references, prefix the word with a \ character. To # include special characters like "<tt>\n</tt>", you'll need to use # two \ characters in normal text, but only one in \<tt> text: # # "\\n" or "<tt>\n</tt>" # # produces: # # "\\n" or "<tt>\n</tt>" # # == Directives # # Directives are keywords surrounded by ":" characters. # # === Controlling what is documented # # [+:nodoc:+ / <tt>:nodoc: all</tt>] # This directive prevents documentation for the element from # being generated. For classes and modules, methods, aliases, # constants, and attributes directly within the affected class or # module also will be omitted. By default, though, modules and # classes within that class or module _will_ be documented. This is # turned off by adding the +all+ modifier. # # module MyModule # :nodoc: # class Input # end # end # # module OtherModule # :nodoc: all # class Output # end # end # # In the above code, only class <tt>MyModule::Input</tt> will be documented. # # The +:nodoc:+ directive, like +:enddoc:+, +:stopdoc:+ and +:startdoc:+ # presented below, is local to the current file: if you do not want to # document a module that appears in several files, specify +:nodoc:+ on each # appearance, at least once per file. # # [+:stopdoc:+ / +:startdoc:+] # Stop and start adding new documentation elements to the current container. # For example, if a class has a number of constants that you don't want to # document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the # last. If you don't specify a +:startdoc:+ by the end of the container, # disables documentation for the rest of the current file. # # [+:doc:+] # Forces a method or attribute to be documented even if it wouldn't be # otherwise. Useful if, for example, you want to include documentation of a # particular private method. # # [+:enddoc:+] # Document nothing further at the current level: directives +:startdoc:+ and # +:doc:+ that appear after this will not be honored for the current container # (file, class or module), in the current file. # # [+:notnew:+ / +:not_new:+ / +:not-new:+ ] # Only applicable to the +initialize+ instance method. Normally RDoc # assumes that the documentation and parameters for +initialize+ are # actually for the +new+ method, and so fakes out a +new+ for the class. # The +:notnew:+ directive stops this. Remember that +initialize+ is private, # so you won't see the documentation unless you use the +-a+ command line # option. # # === Method arguments # # [+:arg:+ or +:args:+ _parameters_] # Overrides the default argument handling with exactly these parameters. # # ## # # :args: a, b # # def some_method(*a) # end # # [+:yield:+ or +:yields:+ _parameters_] # Overrides the default yield discovery with these parameters. # # ## # # :yields: key, value # # def each_thing &block # @things.each(&block) # end # # [+:call-seq:+] # Lines up to the next blank line or lines with a common prefix in the # comment are treated as the method's calling sequence, overriding the # default parsing of method parameters and yield arguments. # # Multiple lines may be used. # # # :call-seq: # # ARGF.readlines(sep=$/) -> array # # ARGF.readlines(limit) -> array # # ARGF.readlines(sep, limit) -> array # # # # ARGF.to_a(sep=$/) -> array # # ARGF.to_a(limit) -> array # # ARGF.to_a(sep, limit) -> array # # # # The remaining lines are documentation ... # # === Sections # # Sections allow you to group methods in a class into sensible containers. If # you use the sections 'Public', 'Internal' and 'Deprecated' (the three # allowed method statuses from TomDoc) the sections will be displayed in that # order placing the most useful methods at the top. Otherwise, sections will # be displayed in alphabetical order. # # [+:category:+ _section_] # Adds this item to the named +section+ overriding the current section. Use # this to group methods by section in RDoc output while maintaining a # sensible ordering (like alphabetical). # # # :category: Utility Methods # # # # CGI escapes +text+ # # def convert_string text # CGI.escapeHTML text # end # # An empty category will place the item in the default category: # # # :category: # # # # This method is in the default category # # def some_method # # ... # end # # Unlike the :section: directive, :category: is not sticky. The category # only applies to the item immediately following the comment. # # Use the :section: directive to provide introductory text for a section of # documentation. # # [+:section:+ _title_] # Provides section introductory text in RDoc output. The title following # +:section:+ is used as the section name and the remainder of the comment # containing the section is used as introductory text. A section's comment # block must be separated from following comment blocks. Use an empty title # to switch to the default section. # # The :section: directive is sticky, so subsequent methods, aliases, # attributes, and classes will be contained in this section until the # section is changed. The :category: directive will override the :section: # directive. # # A :section: comment block may have one or more lines before the :section: # directive. These will be removed, and any identical lines at the end of # the block are also removed. This allows you to add visual cues to the # section. # # Example: # # # ---------------------------------------- # # :section: My Section # # This is the section that I wrote. # # See it glisten in the noon-day sun. # # ---------------------------------------- # # ## # # Comment for some_method # # def some_method # # ... # end # # === Other directives # # [+:markup:+ _type_] # Overrides the default markup type for this comment with the specified # markup type. For Ruby files, if the first comment contains this directive # it is applied automatically to all comments in the file. # # Unless you are converting between markup formats you should use a # <code>.rdoc_options</code> file to specify the default documentation # format for your entire project. See RDoc::Options@Saved+Options for # instructions. # # At the top of a file the +:markup:+ directive applies to the entire file: # # # coding: UTF-8 # # :markup: TomDoc # # # TomDoc comment here ... # # class MyClass # # ... # # For just one comment: # # # ... # end # # # :markup: RDoc # # # # This is a comment in RDoc markup format ... # # def some_method # # ... # # See Markup@CONTRIBUTING for instructions on adding a new markup format. # # [+:include:+ _filename_] # Include the contents of the named file at this point. This directive # must appear alone on one line, possibly preceded by spaces. In this # position, it can be escaped with a \ in front of the first colon. # # The file will be searched for in the directories listed by the +--include+ # option, or in the current directory by default. The contents of the file # will be shifted to have the same indentation as the ':' at the start of # the +:include:+ directive. # # [+:title:+ _text_] # Sets the title for the document. Equivalent to the <tt>--title</tt> # command line parameter. (The command line parameter overrides any :title: # directive in the source). # # [+:main:+ _name_] # Equivalent to the <tt>--main</tt> command line parameter. # #-- # Original Author:: Dave Thomas, dave@pragmaticprogrammer.com # License:: Ruby license class RDoc::Markup ## # An AttributeManager which handles inline markup. attr_reader :attribute_manager ## # Parses +str+ into an RDoc::Markup::Document. def self.parse str RDoc::Markup::Parser.parse str rescue RDoc::Markup::Parser::Error => e $stderr.puts <<-EOF While parsing markup, RDoc encountered a #{e.class}: #{e} \tfrom #{e.backtrace.join "\n\tfrom "} ---8<--- #{text} ---8<--- RDoc #{RDoc::VERSION} Ruby #{RUBY_VERSION}-p#{RUBY_PATCHLEVEL} #{RUBY_RELEASE_DATE} Please file a bug report with the above information at: https://github.com/ruby/rdoc/issues EOF raise end ## # Take a block of text and use various heuristics to determine its # structure (paragraphs, lists, and so on).

(While the # [markdown dingus][dingus] emphasizes in-word underscores, neither the # Markdown syntax nor MarkdownTest mention this behavior.) # # For HTML output, RDoc always auto-links bare URLs. # # ### Break on Newline # # The break_on_newline extension converts all newlines into hard line breaks # as in [Github Flavored Markdown][GFM]. This extension is disabled by # default. # # ### CSS # # The #css extension enables CSS blocks to be included in the output, but they # are not used for any built-in RDoc output format. This extension is disabled # by default. # # Example: # # <style type="text/css"> # h1 { font-size: 3em } # </style> # # ### Definition Lists # # The definition_lists extension allows definition lists using the [PHP # Markdown Extra syntax][PHPE], but only one label and definition are supported # at this time. This extension is enabled by default. # # Example: # # ``` # cat # : A small furry mammal # that seems to sleep a lot # # ant # : A little insect that is known # to enjoy picnics # # ``` # # Produces: # # cat # : A small furry mammal # that seems to sleep a lot # # ant # : A little insect that is known # to enjoy picnics # # ### Strike # # Example: # # ``` # This is ~~striked~~. # ``` # # Produces: # # This is ~~striked~~. # # ### Github # # The #github extension enables a partial set of [Github Flavored Markdown] # [GFM]. This extension is enabled by default. # # Supported github extensions include: # # #### Fenced code blocks # # Use ` ``` ` around a block of code instead of indenting it four spaces. # # #### Syntax highlighting # # Use ` ``` ruby ` as the start of a code fence to add syntax highlighting. # (Currently only `ruby` syntax is supported). # # ### HTML # # Enables raw HTML to be included in the output. This extension is enabled by # default. # # Example: # # <table> # ... # </table> # # ### Notes # # The #notes extension enables footnote support. This extension is enabled by # default. # # Example: # # Here is some text[^1] including an inline footnote ^[for short footnotes] # # ... # # [^1]: With the footnote text down at the bottom # # Produces: # # Here is some text[^1] including an inline footnote ^[for short footnotes] # # [^1]: With the footnote text down at the bottom # # ## Limitations # # * Link titles are not used # * Footnotes are collapsed into a single paragraph # # ## Author # # This markdown parser is a port to kpeg from [peg-markdown][pegmarkdown] by # John MacFarlane. # # It is used under the MIT license: # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to deal # in the Software without restriction, including without limitation the rights # to use, copy, modify, merge, publish, distribute, sublicense, and/or sell # copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2010-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2013-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2010-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2013-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

You can then give the Logger a level, and only messages # at that level or higher will be printed. # # The levels are: # # +UNKNOWN+:: An unknown message that should always be logged. # +FATAL+:: An unhandleable error that results in a program crash. # +ERROR+:: A handleable error condition. # +WARN+:: A warning. # +INFO+:: Generic (useful) information about system operation. # +DEBUG+:: Low-level information for developers. # # For instance, in a production system, you may have your Logger set to # +INFO+ or even +WARN+. # When you are developing the system, however, you probably # want to know about the program's internal state, and would set the Logger to # +DEBUG+. # # *Note*: Logger does not escape or sanitize any messages passed to it. # Developers should be aware of when potentially malicious data (user-input) # is passed to Logger, and manually escape the untrusted data: # # logger.info("User-input: #{input.dump}") # logger.info("User-input: %p" % input) # # You can use #formatter= for escaping all data. # # original_formatter = Logger::Formatter.new # logger.formatter = proc { |severity, datetime, progname, msg| # original_formatter.call(severity, datetime, progname, msg.dump) # } # logger.info(input) # # === Example # # This creates a Logger that outputs to the standard output stream, with a # level of +WARN+: # # require 'logger' # # logger = Logger.new(STDOUT) # logger.level = Logger::WARN # # logger.debug("Created logger") # logger.info("Program started") # logger.warn("Nothing to do!") # # path = "a_non_existent_file" # # begin # File.foreach(path) do |line| # unless line =~ /^(\w+) = (.*)$/ # logger.error("Line in wrong format: #{line.chomp}") # end # end # rescue => err # logger.fatal("Caught exception; exiting") # logger.fatal(err) # end # # Because the Logger's level is set to +WARN+, only the warning, error, and # fatal messages are recorded. The debug and info messages are silently # discarded. # # === Features # # There are several interesting features that Logger provides, like # auto-rolling of log files, setting the format of log messages, and # specifying a program name in conjunction with the message. The next section # shows you how to achieve these things. # # # == HOWTOs # # === How to create a logger # # The options below give you various choices, in more or less increasing # complexity. # # 1. Create a logger which logs messages to STDERR/STDOUT. # # logger = Logger.new(STDERR) # logger = Logger.new(STDOUT) # # 2. Create a logger for the file which has the specified name. # # logger = Logger.new('logfile.log') # # 3. Create a logger for the specified file. # # file = File.open('foo.log', File::WRONLY | File::APPEND) # # To create new logfile, add File::CREAT like: # # file = File.open('foo.log', File::WRONLY | File::APPEND | File::CREAT) # logger = Logger.new(file) # # 4. Create a logger which ages the logfile once it reaches a certain size. # Leave 10 "old" log files where each file is about 1,024,000 bytes. # # logger = Logger.new('foo.log', 10, 1024000) # # 5. Create a logger which ages the logfile daily/weekly/monthly. # # logger = Logger.new('foo.log', 'daily') # logger = Logger.new('foo.log', 'weekly') # logger = Logger.new('foo.log', 'monthly') # # === How to log a message # # Notice the different methods (+fatal+, +error+, +info+) being used to log # messages of various levels? Other methods in this family are +warn+ and # +debug+. +add+ is used below to log a message of an arbitrary (perhaps # dynamic) level. # # 1. Message in a block. # # logger.fatal { "Argument 'foo' not given." } # # 2. Message as a string. # # logger.error "Argument #{@foo} mismatch." # # 3. With progname. # # logger.info('initialize') { "Initializing..." } # # 4. With severity. # # logger.add(Logger::FATAL) { 'Fatal error!' } # # The block form allows you to create potentially complex log messages, # but to delay their evaluation until and unless the message is # logged. For example, if we have the following: # # logger.debug { "This is a " + potentially + " expensive operation" } # # If the logger's level is +INFO+ or higher, no debug messages will be logged, # and the entire block will not even be evaluated. Compare to this: # # logger.debug("This is a " + potentially + " expensive operation") # # Here, the string concatenation is done every time, even if the log # level is not set to show the debug message. # # === How to close a logger # # logger.close # # === Setting severity threshold # # 1. Original interface. # # logger.sev_threshold = Logger::WARN # # 2. Log4r (somewhat) compatible interface. # # logger.level = Logger::INFO # # # DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN # # 3. Symbol or String (case insensitive) # # logger.level = :info # logger.level = 'INFO' # # # :debug < :info < :warn < :error < :fatal < :unknown # # 4. Constructor # # Logger.new(logdev, level: Logger::INFO) # Logger.new(logdev, level: :info) # Logger.new(logdev, level: 'INFO') # # == Format # # Log messages are rendered in the output stream in a certain format by # default. The default format and a sample are shown below: # # Log format: # SeverityID, [DateTime #pid] SeverityLabel -- ProgName: message # # Log sample: # I, [1999-03-03T02:34:24.895701 #19074] INFO -- Main: info. # # You may change the date and time format via #datetime_format=. # # logger.datetime_format = '%Y-%m-%d %H:%M:%S' # # e.g. "2004-01-03 00:54:26" # # or via the constructor. # # Logger.new(logdev, datetime_format: '%Y-%m-%d %H:%M:%S') # # Or, you may change the overall format via the #formatter= method. # # logger.formatter = proc do |severity, datetime, progname, msg| # "#{datetime}: #{msg}\n" # end # # e.g. "2005-09-22 08:51:08 +0900: hello world" # # or via the constructor. # # Logger.new(logdev, formatter: proc {|severity, datetime, progname, msg| # "#{datetime}: #{msg}\n" # }) # class Logger _, name, rev = %w$Id$ if name name = name.chomp(",v") else name = File.basename(__FILE__) end rev ||= "v#{VERSION}" ProgName = "#{name}/#{rev}" include Severity # Logging severity threshold (e.g. <tt>Logger::INFO</tt>). attr_reader :level # Set logging severity threshold. # # +severity+:: The Severity of the log message. def level=(severity) if severity.is_a?(Integer) @level = severity else case severity.to_s.downcase when 'debug' @level = DEBUG when 'info' @level = INFO when 'warn' @level = WARN when 'error' @level = ERROR when 'fatal' @level = FATAL when 'unknown' @level = UNKNOWN else raise ArgumentError, "invalid log level: #{severity}" end end end # Program name to include in log messages. attr_accessor :progname # Set date-time format. # # +datetime_format+:: A string suitable for passing to +strftime+. def datetime_format=(datetime_format) @default_formatter.datetime_format = datetime_format end # Returns the date format being used.

The -o option can change the output filename. # # == Writing A Racc Grammar File # # If you want your own parser, you have to write a grammar file. # A grammar file contains the name of your parser class, grammar for the parser, # user code, and anything else. # When writing a grammar file, yacc's knowledge is helpful. # If you have not used yacc before, Racc is not too difficult. # # Here's an example Racc grammar file. # # class Calcparser # rule # target: exp { print val[0] } # # exp: exp '+' exp # | exp '*' exp # | '(' exp ')' # | NUMBER # end # # Racc grammar files resemble yacc files. # But (of course), this is Ruby code. # yacc's $$ is the 'result', $0, $1... is # an array called 'val', and $-1, $-2... is an array called '_values'. # # See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for # more information on grammar files. # # == Parser # # Then you must prepare the parse entry method. There are two types of # parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse # # Racc::Parser#do_parse is simple. # # It's yyparse() of yacc, and Racc::Parser#next_token is yylex(). # This method must returns an array like [TOKENSYMBOL, ITS_VALUE]. # EOF is [false, false]. # (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default. # If you want to change this, see the grammar reference. # # Racc::Parser#yyparse is little complicated, but useful. # It does not use Racc::Parser#next_token, instead it gets tokens from any iterator. # # For example, <code>yyparse(obj, :scan)</code> causes # calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+. # # == Debugging # # When debugging, "-v" or/and the "-g" option is helpful. # # "-v" creates verbose log file (.output). # "-g" creates a "Verbose Parser". # Verbose Parser prints the internal status when parsing. # But it's _not_ automatic. # You must use -g option and set +@yydebug+ to +true+ in order to get output. # -g option only creates the verbose parser. # # === Racc reported syntax error. # # Isn't there too many "end"? # grammar of racc file is changed in v0.10. # # Racc does not use '%' mark, while yacc uses huge number of '%' marks.. # # === Racc reported "XXXX conflicts". # # Try "racc -v xxxx.y". # It causes producing racc's internal log file, xxxx.output. # # === Generated parsers does not work correctly # # Try "racc -g xxxx.y". # This command let racc generate "debugging parser". # Then set @yydebug=true in your parser. # It produces a working log of your parser. # # == Re-distributing Racc runtime # # A parser, which is created by Racc, requires the Racc runtime module; # racc/parser.rb. # # Ruby 1.8.x comes with Racc runtime module, # you need NOT distribute Racc runtime files. # # If you want to include the Racc runtime module with your parser. # This can be done by using '-E' option: # # $ racc -E -omyparser.rb myparser.y # # This command creates myparser.rb which `includes' Racc runtime. # Only you must do is to distribute your parser file (myparser.rb). # # Note: parser.rb is ruby license, but your parser is not. # Your own parser is completely yours. module Racc unless defined?(Racc_No_Extensions) Racc_No_Extensions = false # :nodoc: end class Parser Racc_Runtime_Version = ::Racc::VERSION Racc_Runtime_Core_Version_R = ::Racc::VERSION begin if Object.const_defined?(:RUBY_ENGINE) and RUBY_ENGINE == 'jruby' require 'jruby' require 'racc/cparse-jruby.jar' com.headius.racc.Cparse.new.load(JRuby.runtime, false) else require 'racc/cparse' end unless new.respond_to?(:_racc_do_parse_c, true) raise LoadError, 'old cparse.so' end if Racc_No_Extensions raise LoadError, 'selecting ruby version of racc runtime core' end Racc_Main_Parsing_Routine = :_racc_do_parse_c # :nodoc: Racc_YY_Parse_Method = :_racc_yyparse_c # :nodoc: Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_C # :nodoc: Racc_Runtime_Type = 'c' # :nodoc: rescue LoadError Racc_Main_Parsing_Routine = :_racc_do_parse_rb Racc_YY_Parse_Method = :_racc_yyparse_rb Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_R Racc_Runtime_Type = 'ruby' end def Parser.racc_runtime_type # :nodoc: Racc_Runtime_Type end def _racc_setup @yydebug = false unless self.class::Racc_debug_parser @yydebug = false unless defined?(@yydebug) if @yydebug @racc_debug_out = $stderr unless defined?(@racc_debug_out) @racc_debug_out ||= $stderr end arg = self.class::Racc_arg arg[13] = true if arg.size < 14 arg end def _racc_init_sysvars @racc_state = [0] @racc_tstack = [] @racc_vstack = [] @racc_t = nil @racc_val = nil @racc_read_next = true @racc_user_yyerror = false @racc_error_status = 0 end # The entry point of the parser.

The system time zone is taken from # <tt>Time.local(year, 1, 1).zone</tt> and # <tt>Time.local(year, 7, 1).zone</tt>. # If the extracted time zone abbreviation does not match any of them, # it is ignored and the given time is regarded as a local time. # # ArgumentError is raised if Date._parse cannot extract information from # +date+ or if the Time class cannot represent specified date. # # This method can be used as a fail-safe for other parsing methods as: # # Time.rfc2822(date) rescue Time.parse(date) # Time.httpdate(date) rescue Time.parse(date) # Time.xmlschema(date) rescue Time.parse(date) # # A failure of Time.parse should be checked, though. # # You must require 'time' to use this method. # def parse(date, now=self.now) comp = !block_given? d = Date._parse(date, comp) year = d[:year] year = yield(year) if year && !comp make_time(date, year, d[:yday], d[:mon], d[:mday], d[:hour], d[:min], d[:sec], d[:sec_fraction], d[:zone], now) end # # Works similar to +parse+ except that instead of using a # heuristic to detect the format of the input string, you provide # a second argument that describes the format of the string. # # If a block is given, the year described in +date+ is converted by the # block.

Using # ERB, actual Ruby code can be added to any plain text document for the # purposes of generating document information details and/or flow control. # # A very simple example is this: # # require 'erb' # # x = 42 # template = ERB.new <<-EOF # The value of x is: <%= x %> # EOF # puts template.result(binding) # # <em>Prints:</em> The value of x is: 42 # # More complex examples are given below. # # # == Recognized Tags # # ERB recognizes certain tags in the provided template and converts them based # on the rules below: # # <% Ruby code -- inline with output %> # <%= Ruby expression -- replace with result %> # <%# comment -- ignored -- useful in testing %> # % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new) # %% replaced with % if first thing on a line and % processing is used # <%% or %%> -- replace with <% or %> respectively # # All other text is passed through ERB filtering unchanged. # # # == Options # # There are several settings you can change when you use ERB: # * the nature of the tags that are recognized; # * the binding used to resolve local variables in the template. # # See the ERB.new and ERB#result methods for more detail. # # == Character encodings # # ERB (or Ruby code generated by ERB) returns a string in the same # character encoding as the input string. When the input string has # a magic comment, however, it returns a string in the encoding specified # by the magic comment. # # # -*- coding: utf-8 -*- # require 'erb' # # template = ERB.new <<EOF # <%#-*- coding: Big5 -*-%> # \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>. # EOF # puts template.result # # <em>Prints:</em> \_\_ENCODING\_\_ is Big5. # # # == Examples # # === Plain Text # # ERB is useful for any generic templating situation.

A Tempfile # objects behaves just like a File object, and you can perform all the usual # file operations on it: reading data, writing data, changing its permissions, # etc. So although this class does not explicitly document all instance methods # supported by File, you can in fact call any File instance method on a # Tempfile object. # # == Synopsis # # require 'tempfile' # # file = Tempfile.new('foo') # file.path # => A unique filename in the OS's temp directory, # # e.g.: "/tmp/foo.24722.0" # # This filename contains 'foo' in its basename. # file.write("hello world") # file.rewind # file.read # => "hello world" # file.close # file.unlink # deletes the temp file # # == Good practices # # === Explicit close # # When a Tempfile object is garbage collected, or when the Ruby interpreter # exits, its associated temporary file is automatically deleted. This means # that's it's unnecessary to explicitly delete a Tempfile after use, though # it's good practice to do so: not explicitly deleting unused Tempfiles can # potentially leave behind large amounts of tempfiles on the filesystem # until they're garbage collected. The existence of these temp files can make # it harder to determine a new Tempfile filename. # # Therefore, one should always call #unlink or close in an ensure block, like # this: # # file = Tempfile.new('foo') # begin # # ...do something with file... # ensure # file.close # file.unlink # deletes the temp file # end # # Tempfile.create { ... } exists for this purpose and is more convenient to use. # Note that Tempfile.create returns a File instance instead of a Tempfile, which # also avoids the overhead and complications of delegation. # # Tempfile.open('foo') do |file| # # ...do something with file... # end # # === Unlink after creation # # On POSIX systems, it's possible to unlink a file right after creating it, # and before closing it. This removes the filesystem entry without closing # the file handle, so it ensures that only the processes that already had # the file handle open can access the file's contents. It's strongly # recommended that you do this if you do not want any other processes to # be able to read from or write to the Tempfile, and you do not need to # know the Tempfile's filename either. # # For example, a practical use case for unlink-after-creation would be this: # you need a large byte buffer that's too large to comfortably fit in RAM, # e.g. when you're writing a web server and you want to buffer the client's # file upload data. # # Please refer to #unlink for more information and a code example. # # == Minor notes # # Tempfile's filename picking method is both thread-safe and inter-process-safe: # it guarantees that no other threads or processes will pick the same filename. # # Tempfile itself however may not be entirely thread-safe. If you access the # same Tempfile object from multiple threads then you should protect it with a # mutex. class Tempfile < DelegateClass(File) # Creates a temporary file with permissions 0600 (= only readable and # writable by the owner) and opens it with mode "w+". # # It is recommended to use Tempfile.create { ... } instead when possible, # because that method avoids the cost of delegation and does not rely on a # finalizer to close and unlink the file, which is unreliable. # # The +basename+ parameter is used to determine the name of the # temporary file. You can either pass a String or an Array with # 2 String elements. In the former form, the temporary file's base # name will begin with the given string. In the latter form, # the temporary file's base name will begin with the array's first # element, and end with the second element. For example: # # file = Tempfile.new('hello') # file.path # => something like: "/tmp/hello2843-8392-92849382--0" # # # Use the Array form to enforce an extension in the filename: # file = Tempfile.new(['hello', '.jpg']) # file.path # => something like: "/tmp/hello2843-8392-92849382--0.jpg" # # The temporary file will be placed in the directory as specified # by the +tmpdir+ parameter. By default, this is +Dir.tmpdir+. # # file = Tempfile.new('hello', '/home/aisaka') # file.path # => something like: "/home/aisaka/hello2843-8392-92849382--0" # # You can also pass an options hash. Under the hood, Tempfile creates # the temporary file using +File.open+. These options will be passed to # +File.open+. This is mostly useful for specifying encoding # options, e.g.: # # Tempfile.new('hello', '/home/aisaka', encoding: 'ascii-8bit') # # # You can also omit the 'tmpdir' parameter: # Tempfile.new('hello', encoding: 'ascii-8bit') # # Note: +mode+ keyword argument, as accepted by Tempfile, can only be # numeric, combination of the modes defined in File::Constants. # # === Exceptions # # If Tempfile.new cannot find a unique filename within a limited # number of tries, then it will raise an exception. def initialize(basename="", tmpdir=nil, mode: 0, **options) warn "Tempfile.new doesn't call the given block.", uplevel: 1 if block_given? @unlinked = false @mode = mode|File::RDWR|File::CREAT|File::EXCL ::Dir::Tmpname.create(basename, tmpdir, **options) do |tmpname, n, opts| opts[:perm] = 0600 @tmpfile = File.open(tmpname, @mode, **opts) @opts = opts.freeze end ObjectSpace.define_finalizer(self, Remover.new(@tmpfile)) super(@tmpfile) end # Opens or reopens the file with mode "r+". def open _close mode = @mode & ~(File::CREAT|File::EXCL) @tmpfile = File.open(@tmpfile.path, mode, **@opts) __setobj__(@tmpfile) end def _close # :nodoc: @tmpfile.close end protected :_close # Closes the file.

Basically, a CGI program is called with the parameters # of the request passed in either in the environment (GET) or via $stdin # (POST), and everything it prints to $stdout is returned to the client. # # This file holds the CGI class. This class provides functionality for # retrieving HTTP request parameters, managing cookies, and generating HTML # output. # # The file CGI::Session provides session management functionality; see that # class for more details. # # See http://www.w3.org/CGI/ for more information on the CGI protocol. # # == Introduction # # CGI is a large class, providing several categories of methods, many of which # are mixed in from other modules. Some of the documentation is in this class, # some in the modules CGI::QueryExtension and CGI::HtmlExtension. See # CGI::Cookie for specific information on handling cookies, and cgi/session.rb # (CGI::Session) for information on sessions. # # For queries, CGI provides methods to get at environmental variables, # parameters, cookies, and multipart request data. For responses, CGI provides # methods for writing output and generating HTML. # # Read on for more details. Examples are provided at the bottom. # # == Queries # # The CGI class dynamically mixes in parameter and cookie-parsing # functionality, environmental variable access, and support for # parsing multipart requests (including uploaded files) from the # CGI::QueryExtension module. # # === Environmental Variables # # The standard CGI environmental variables are available as read-only # attributes of a CGI object. The following is a list of these variables: # # # AUTH_TYPE HTTP_HOST REMOTE_IDENT # CONTENT_LENGTH HTTP_NEGOTIATE REMOTE_USER # CONTENT_TYPE HTTP_PRAGMA REQUEST_METHOD # GATEWAY_INTERFACE HTTP_REFERER SCRIPT_NAME # HTTP_ACCEPT HTTP_USER_AGENT SERVER_NAME # HTTP_ACCEPT_CHARSET PATH_INFO SERVER_PORT # HTTP_ACCEPT_ENCODING PATH_TRANSLATED SERVER_PROTOCOL # HTTP_ACCEPT_LANGUAGE QUERY_STRING SERVER_SOFTWARE # HTTP_CACHE_CONTROL REMOTE_ADDR # HTTP_FROM REMOTE_HOST # # # For each of these variables, there is a corresponding attribute with the # same name, except all lower case and without a preceding HTTP_. # +content_length+ and +server_port+ are integers; the rest are strings. # # === Parameters # # The method #params() returns a hash of all parameters in the request as # name/value-list pairs, where the value-list is an Array of one or more # values. The CGI object itself also behaves as a hash of parameter names # to values, but only returns a single value (as a String) for each # parameter name. # # For instance, suppose the request contains the parameter # "favourite_colours" with the multiple values "blue" and "green". The # following behavior would occur: # # cgi.params["favourite_colours"] # => ["blue", "green"] # cgi["favourite_colours"] # => "blue" # # If a parameter does not exist, the former method will return an empty # array, the latter an empty string. The simplest way to test for existence # of a parameter is by the #has_key? method. # # === Cookies # # HTTP Cookies are automatically parsed from the request. They are available # from the #cookies() accessor, which returns a hash from cookie name to # CGI::Cookie object. # # === Multipart requests # # If a request's method is POST and its content type is multipart/form-data, # then it may contain uploaded files. These are stored by the QueryExtension # module in the parameters of the request. The parameter name is the name # attribute of the file input field, as usual. However, the value is not # a string, but an IO object, either an IOString for small files, or a # Tempfile for larger ones. This object also has the additional singleton # methods: # # #local_path():: the path of the uploaded file on the local filesystem # #original_filename():: the name of the file on the client computer # #content_type():: the content type of the file # # == Responses # # The CGI class provides methods for sending header and content output to # the HTTP client, and mixes in methods for programmatic HTML generation # from CGI::HtmlExtension and CGI::TagMaker modules. The precise version of HTML # to use for HTML generation is specified at object creation time. # # === Writing output # # The simplest way to send output to the HTTP client is using the #out() method. # This takes the HTTP headers as a hash parameter, and the body content # via a block. The headers can be generated as a string using the #http_header() # method. The output stream can be written directly to using the #print() # method. # # === Generating HTML # # Each HTML element has a corresponding method for generating that # element as a String. The name of this method is the same as that # of the element, all lowercase. The attributes of the element are # passed in as a hash, and the body as a no-argument block that evaluates # to a String. The HTML generation module knows which elements are # always empty, and silently drops any passed-in body. It also knows # which elements require matching closing tags and which don't. However, # it does not know what attributes are legal for which elements. # # There are also some additional HTML generation methods mixed in from # the CGI::HtmlExtension module. These include individual methods for the # different types of form inputs, and methods for elements that commonly # take particular attributes where the attributes can be directly specified # as arguments, rather than via a hash. # # === Utility HTML escape and other methods like a function. # # There are some utility tool defined in cgi/util.rb . # And when include, you can use utility methods like a function. # # == Examples of use # # === Get form values # # require "cgi" # cgi = CGI.new # value = cgi['field_name'] # <== value string for 'field_name' # # if not 'field_name' included, then return "". # fields = cgi.keys # <== array of field names # # # returns true if form has 'field_name' # cgi.has_key?('field_name') # cgi.has_key?('field_name') # cgi.include?('field_name') # # CAUTION! cgi['field_name'] returned an Array with the old # cgi.rb(included in Ruby 1.6) # # === Get form values as hash # # require "cgi" # cgi = CGI.new # params = cgi.params # # cgi.params is a hash. # # cgi.params['new_field_name'] = ["value"] # add new param # cgi.params['field_name'] = ["new_value"] # change value # cgi.params.delete('field_name') # delete param # cgi.params.clear # delete all params # # # === Save form values to file # # require "pstore" # db = PStore.new("query.db") # db.transaction do # db["params"] = cgi.params # end # # # === Restore form values from file # # require "pstore" # db = PStore.new("query.db") # db.transaction do # cgi.params = db["params"] # end # # # === Get multipart form values # # require "cgi" # cgi = CGI.new # value = cgi['field_name'] # <== value string for 'field_name' # value.read # <== body of value # value.local_path # <== path to local file of value # value.original_filename # <== original filename of value # value.content_type # <== content_type of value # # and value has StringIO or Tempfile class methods. # # === Get cookie values # # require "cgi" # cgi = CGI.new # values = cgi.cookies['name'] # <== array of 'name' # # if not 'name' included, then return []. # names = cgi.cookies.keys # <== array of cookie names # # and cgi.cookies is a hash. # # === Get cookie objects # # require "cgi" # cgi = CGI.new # for name, cookie in cgi.cookies # cookie.expires = Time.now + 30 # end # cgi.out("cookie" => cgi.cookies) {"string"} # # cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... } # # require "cgi" # cgi = CGI.new # cgi.cookies['name'].expires = Time.now + 30 # cgi.out("cookie" => cgi.cookies['name']) {"string"} # # === Print http header and html string to $DEFAULT_OUTPUT ($>) # # require "cgi" # cgi = CGI.new("html4") # add HTML generation methods # cgi.out do # cgi.html do # cgi.head do # cgi.title { "TITLE" } # end + # cgi.body do # cgi.form("ACTION" => "uri") do # cgi.p do # cgi.textarea("get_text") + # cgi.br + # cgi.submit # end # end + # cgi.pre do # CGI.escapeHTML( # "params: #{cgi.params.inspect}\n" + # "cookies: #{cgi.cookies.inspect}\n" + # ENV.collect do |key, value| # "#{key} --> #{value}\n" # end.join("") # ) # end # end # end # end # # # add HTML generation methods # CGI.new("html3") # html3.2 # CGI.new("html4") # html4.01 (Strict) # CGI.new("html4Tr") # html4.01 Transitional # CGI.new("html4Fr") # html4.01 Frameset # CGI.new("html5") # html5 # # === Some utility methods # # require 'cgi/util' # CGI.escapeHTML('Usage: foo "bar" <baz>') # # # === Some utility methods like a function # # require 'cgi/util' # include CGI::Util # escapeHTML('Usage: foo "bar" <baz>') # h('Usage: foo "bar" <baz>') # alias # # class CGI VERSION = "0.2.2" end require 'cgi/core' require 'cgi/cookie' require 'cgi/util' CGI.autoload(:HtmlExtension, 'cgi/html') ruby/prettyprint.rb 0000644 00000037631 15102661024 0010465 0 ustar 00 # frozen_string_literal: true # # This class implements a pretty printing algorithm.

The protocol is described in [IMAP]. # # == IMAP Overview # # An IMAP client connects to a server, and then authenticates # itself using either #authenticate() or #login(). Having # authenticated itself, there is a range of commands # available to it. Most work with mailboxes, which may be # arranged in an hierarchical namespace, and each of which # contains zero or more messages. How this is implemented on # the server is implementation-dependent; on a UNIX server, it # will frequently be implemented as files in mailbox format # within a hierarchy of directories. # # To work on the messages within a mailbox, the client must # first select that mailbox, using either #select() or (for # read-only access) #examine(). Once the client has successfully # selected a mailbox, they enter _selected_ state, and that # mailbox becomes the _current_ mailbox, on which mail-item # related commands implicitly operate. # # Messages have two sorts of identifiers: message sequence # numbers and UIDs. # # Message sequence numbers number messages within a mailbox # from 1 up to the number of items in the mailbox. If a new # message arrives during a session, it receives a sequence # number equal to the new size of the mailbox. If messages # are expunged from the mailbox, remaining messages have their # sequence numbers "shuffled down" to fill the gaps. # # UIDs, on the other hand, are permanently guaranteed not to # identify another message within the same mailbox, even if # the existing message is deleted. UIDs are required to # be assigned in ascending (but not necessarily sequential) # order within a mailbox; this means that if a non-IMAP client # rearranges the order of mailitems within a mailbox, the # UIDs have to be reassigned. An IMAP client thus cannot # rearrange message orders. # # == Examples of Usage # # === List sender and subject of all recent messages in the default mailbox # # imap = Net::IMAP.new('mail.example.com') # imap.authenticate('LOGIN', 'joe_user', 'joes_password') # imap.examine('INBOX') # imap.search(["RECENT"]).each do |message_id| # envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"] # puts "#{envelope.from[0].name}: \t#{envelope.subject}" # end # # === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03" # # imap = Net::IMAP.new('mail.example.com') # imap.authenticate('LOGIN', 'joe_user', 'joes_password') # imap.select('Mail/sent-mail') # if not imap.list('Mail/', 'sent-apr03') # imap.create('Mail/sent-apr03') # end # imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id| # imap.copy(message_id, "Mail/sent-apr03") # imap.store(message_id, "+FLAGS", [:Deleted]) # end # imap.expunge # # == Thread Safety # # Net::IMAP supports concurrent threads. For example, # # imap = Net::IMAP.new("imap.foo.net", "imap2") # imap.authenticate("cram-md5", "bar", "password") # imap.select("inbox") # fetch_thread = Thread.start { imap.fetch(1..-1, "UID") } # search_result = imap.search(["BODY", "hello"]) # fetch_result = fetch_thread.value # imap.disconnect # # This script invokes the FETCH command and the SEARCH command concurrently. # # == Errors # # An IMAP server can send three different types of responses to indicate # failure: # # NO:: the attempted command could not be successfully completed. For # instance, the username/password used for logging in are incorrect; # the selected mailbox does not exist; etc. # # BAD:: the request from the client does not follow the server's # understanding of the IMAP protocol. This includes attempting # commands from the wrong client state; for instance, attempting # to perform a SEARCH command without having SELECTed a current # mailbox. It can also signal an internal server # failure (such as a disk crash) has occurred. # # BYE:: the server is saying goodbye. This can be part of a normal # logout sequence, and can be used as part of a login sequence # to indicate that the server is (for some reason) unwilling # to accept your connection. As a response to any other command, # it indicates either that the server is shutting down, or that # the server is timing out the client connection due to inactivity. # # These three error response are represented by the errors # Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and # Net::IMAP::ByeResponseError, all of which are subclasses of # Net::IMAP::ResponseError. Essentially, all methods that involve # sending a request to the server can generate one of these errors. # Only the most pertinent instances have been documented below. # # Because the IMAP class uses Sockets for communication, its methods # are also susceptible to the various errors that can occur when # working with sockets. These are generally represented as # Errno errors. For instance, any method that involves sending a # request to the server and/or receiving a response from it could # raise an Errno::EPIPE error if the network connection unexpectedly # goes down. See the socket(7), ip(7), tcp(7), socket(2), connect(2), # and associated man pages. # # Finally, a Net::IMAP::DataFormatError is thrown if low-level data # is found to be in an incorrect format (for instance, when converting # between UTF-8 and UTF-16), and Net::IMAP::ResponseParseError is # thrown if a server response is non-parseable. # # # == References # # [[IMAP]] # M.

For details # of POP3, see [RFC1939] (http://www.ietf.org/rfc/rfc1939.txt). # # == Examples # # === Retrieving Messages # # This example retrieves messages from the server and deletes them # on the server. # # Messages are written to files named 'inbox/1', 'inbox/2', .... # Replace 'pop.example.com' with your POP3 server address, and # 'YourAccount' and 'YourPassword' with the appropriate account # details. # # require 'net/pop' # # pop = Net::POP3.new('pop.example.com') # pop.start('YourAccount', 'YourPassword') # (1) # if pop.mails.empty? # puts 'No mail.' # else # i = 0 # pop.each_mail do |m| # or "pop.mails.each ..." # (2) # File.open("inbox/#{i}", 'w') do |f| # f.write m.pop # end # m.delete # i += 1 # end # puts "#{pop.mails.size} mails popped." # end # pop.finish # (3) # # 1. Call Net::POP3#start and start POP session. # 2. Access messages by using POP3#each_mail and/or POP3#mails. # 3. Close POP session by calling POP3#finish or use the block form of #start. # # === Shortened Code # # The example above is very verbose. You can shorten the code by using # some utility methods. First, the block form of Net::POP3.start can # be used instead of POP3.new, POP3#start and POP3#finish. # # require 'net/pop' # # Net::POP3.start('pop.example.com', 110, # 'YourAccount', 'YourPassword') do |pop| # if pop.mails.empty? # puts 'No mail.' # else # i = 0 # pop.each_mail do |m| # or "pop.mails.each ..." # File.open("inbox/#{i}", 'w') do |f| # f.write m.pop # end # m.delete # i += 1 # end # puts "#{pop.mails.size} mails popped." # end # end # # POP3#delete_all is an alternative for #each_mail and #delete. # # require 'net/pop' # # Net::POP3.start('pop.example.com', 110, # 'YourAccount', 'YourPassword') do |pop| # if pop.mails.empty? # puts 'No mail.' # else # i = 1 # pop.delete_all do |m| # File.open("inbox/#{i}", 'w') do |f| # f.write m.pop # end # i += 1 # end # end # end # # And here is an even shorter example. # # require 'net/pop' # # i = 0 # Net::POP3.delete_all('pop.example.com', 110, # 'YourAccount', 'YourPassword') do |m| # File.open("inbox/#{i}", 'w') do |f| # f.write m.pop # end # i += 1 # end # # === Memory Space Issues # # All the examples above get each message as one big string. # This example avoids this. # # require 'net/pop' # # i = 1 # Net::POP3.delete_all('pop.example.com', 110, # 'YourAccount', 'YourPassword') do |m| # File.open("inbox/#{i}", 'w') do |f| # m.pop do |chunk| # get a message little by little. # f.write chunk # end # i += 1 # end # end # # === Using APOP # # The net/pop library supports APOP authentication. # To use APOP, use the Net::APOP class instead of the Net::POP3 class. # You can use the utility method, Net::POP3.APOP(). For example: # # require 'net/pop' # # # Use APOP authentication if $isapop == true # pop = Net::POP3.APOP($isapop).new('apop.example.com', 110) # pop.start('YourAccount', 'YourPassword') do |pop| # # Rest of the code is the same. # end # # === Fetch Only Selected Mail Using 'UIDL' POP Command # # If your POP server provides UIDL functionality, # you can grab only selected mails from the POP server. # e.g. # # def need_pop?( id ) # # determine if we need pop this mail... # end # # Net::POP3.start('pop.example.com', 110, # 'Your account', 'Your password') do |pop| # pop.mails.select { |m| need_pop?(m.unique_id) }.each do |m| # do_something(m.pop) # end # end # # The POPMail#unique_id() method returns the unique-id of the message as a # String. Normally the unique-id is a hash of the message. # class POP3 < Protocol # version of this library VERSION = "0.1.1" # # Class Parameters # # returns the port for POP3 def POP3.default_port default_pop3_port() end # The default port for POP3 connections, port 110 def POP3.default_pop3_port 110 end # The default port for POP3S connections, port 995 def POP3.default_pop3s_port 995 end def POP3.socket_type #:nodoc: obsolete Net::InternetMessageIO end # # Utilities # # Returns the APOP class if +isapop+ is true; otherwise, returns # the POP class.

Using SMTP.start with a block is the simplest # way to do this. This way, the SMTP connection is closed automatically # after the block is executed. # # require 'net/smtp' # Net::SMTP.start('your.smtp.server', 25) do |smtp| # # Use the SMTP object smtp only in this block. # end # # Replace 'your.smtp.server' with your SMTP server. Normally # your system manager or internet provider supplies a server # for you. # # Then you can send messages. # # msgstr = <<END_OF_MESSAGE # From: Your Name <your@mail.address> # To: Destination Address <someone@example.com> # Subject: test message # Date: Sat, 23 Jun 2001 16:26:43 +0900 # Message-Id: <unique.message.id.string@example.com> # # This is a test message. # END_OF_MESSAGE # # require 'net/smtp' # Net::SMTP.start('your.smtp.server', 25) do |smtp| # smtp.send_message msgstr, # 'your@mail.address', # 'his_address@example.com' # end # # === Closing the Session # # You MUST close the SMTP session after sending messages, by calling # the #finish method: # # # using SMTP#finish # smtp = Net::SMTP.start('your.smtp.server', 25) # smtp.send_message msgstr, 'from@address', 'to@address' # smtp.finish # # You can also use the block form of SMTP.start/SMTP#start. This closes # the SMTP session automatically: # # # using block form of SMTP.start # Net::SMTP.start('your.smtp.server', 25) do |smtp| # smtp.send_message msgstr, 'from@address', 'to@address' # end # # I strongly recommend this scheme. This form is simpler and more robust. # # === HELO domain # # In almost all situations, you must provide a third argument # to SMTP.start/SMTP#start. This is the domain name which you are on # (the host to send mail from). It is called the "HELO domain". # The SMTP server will judge whether it should send or reject # the SMTP session by inspecting the HELO domain. # # Net::SMTP.start('your.smtp.server', 25 # helo: 'mail.from.domain') { |smtp| ... } # # === SMTP Authentication # # The Net::SMTP class supports three authentication schemes; # PLAIN, LOGIN and CRAM MD5.

They are not recommended if you are performing many HTTP # requests. # # === GET # # Net::HTTP.get('example.com', '/index.html') # => String # # === GET by URI # # uri = URI('http://example.com/index.html?count=10') # Net::HTTP.get(uri) # => String # # === GET with Dynamic Parameters # # uri = URI('http://example.com/index.html') # params = { :limit => 10, :page => 3 } # uri.query = URI.encode_www_form(params) # # res = Net::HTTP.get_response(uri) # puts res.body if res.is_a?(Net::HTTPSuccess) # # === POST # # uri = URI('http://www.example.com/search.cgi') # res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50') # puts res.body # # === POST with Multiple Values # # uri = URI('http://www.example.com/search.cgi') # res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50') # puts res.body # # == How to use Net::HTTP # # The following example code can be used as the basis of an HTTP user-agent # which can perform a variety of request types using persistent # connections. # # uri = URI('http://example.com/some_path?query=string') # # Net::HTTP.start(uri.host, uri.port) do |http| # request = Net::HTTP::Get.new uri # # response = http.request request # Net::HTTPResponse object # end # # Net::HTTP::start immediately creates a connection to an HTTP server which # is kept open for the duration of the block. The connection will remain # open for multiple requests in the block if the server indicates it # supports persistent connections. # # If you wish to re-use a connection across multiple HTTP requests without # automatically closing it you can use ::new and then call #start and # #finish manually. # # The request types Net::HTTP supports are listed below in the section "HTTP # Request Classes". # # For all the Net::HTTP request objects and shortcut request methods you may # supply either a String for the request path or a URI from which Net::HTTP # will extract the request path. # # === Response Data # # uri = URI('http://example.com/index.html') # res = Net::HTTP.get_response(uri) # # # Headers # res['Set-Cookie'] # => String # res.get_fields('set-cookie') # => Array # res.to_hash['set-cookie'] # => Array # puts "Headers: #{res.to_hash.inspect}" # # # Status # puts res.code # => '200' # puts res.message # => 'OK' # puts res.class.name # => 'HTTPOK' # # # Body # puts res.body if res.response_body_permitted? # # === Following Redirection # # Each Net::HTTPResponse object belongs to a class for its response code. # # For example, all 2XX responses are instances of a Net::HTTPSuccess # subclass, a 3XX response is an instance of a Net::HTTPRedirection # subclass and a 200 response is an instance of the Net::HTTPOK class. For # details of response classes, see the section "HTTP Response Classes" # below. # # Using a case statement you can handle various types of responses properly: # # def fetch(uri_str, limit = 10) # # You should choose a better exception. # raise ArgumentError, 'too many HTTP redirects' if limit == 0 # # response = Net::HTTP.get_response(URI(uri_str)) # # case response # when Net::HTTPSuccess then # response # when Net::HTTPRedirection then # location = response['location'] # warn "redirected to #{location}" # fetch(location, limit - 1) # else # response.value # end # end # # print fetch('http://www.ruby-lang.org') # # === POST # # A POST can be made using the Net::HTTP::Post request class. This example # creates a URL encoded POST body: # # uri = URI('http://www.example.com/todo.cgi') # req = Net::HTTP::Post.new(uri) # req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31') # # res = Net::HTTP.start(uri.hostname, uri.port) do |http| # http.request(req) # end # # case res # when Net::HTTPSuccess, Net::HTTPRedirection # # OK # else # res.value # end # # To send multipart/form-data use Net::HTTPHeader#set_form: # # req = Net::HTTP::Post.new(uri) # req.set_form([['upload', File.open('foo.bar')]], 'multipart/form-data') # # Other requests that can contain a body such as PUT can be created in the # same way using the corresponding request class (Net::HTTP::Put). # # === Setting Headers # # The following example performs a conditional GET using the # If-Modified-Since header. If the files has not been modified since the # time in the header a Not Modified response will be returned. See RFC 2616 # section 9.3 for further details. # # uri = URI('http://example.com/cached_response') # file = File.stat 'cached_response' # # req = Net::HTTP::Get.new(uri) # req['If-Modified-Since'] = file.mtime.rfc2822 # # res = Net::HTTP.start(uri.hostname, uri.port) {|http| # http.request(req) # } # # open 'cached_response', 'w' do |io| # io.write res.body # end if res.is_a?(Net::HTTPSuccess) # # === Basic Authentication # # Basic authentication is performed according to # [RFC2617](http://www.ietf.org/rfc/rfc2617.txt). # # uri = URI('http://example.com/index.html?key=value') # # req = Net::HTTP::Get.new(uri) # req.basic_auth 'user', 'pass' # # res = Net::HTTP.start(uri.hostname, uri.port) {|http| # http.request(req) # } # puts res.body # # === Streaming Response Bodies # # By default Net::HTTP reads an entire response into memory. If you are # handling large files or wish to implement a progress bar you can instead # stream the body directly to an IO. # # uri = URI('http://example.com/large_file') # # Net::HTTP.start(uri.host, uri.port) do |http| # request = Net::HTTP::Get.new uri # # http.request request do |response| # open 'large_file', 'w' do |io| # response.read_body do |chunk| # io.write chunk # end # end # end # end # # === HTTPS # # HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=. # # uri = URI('https://secure.example.com/some_path?query=string') # # Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http| # request = Net::HTTP::Get.new uri # response = http.request request # Net::HTTPResponse object # end # # Or if you simply want to make a GET request, you may pass in an URI # object that has an HTTPS URL. Net::HTTP automatically turns on TLS # verification if the URI object has a 'https' URI scheme. # # uri = URI('https://example.com/') # Net::HTTP.get(uri) # => String # # In previous versions of Ruby you would need to require 'net/https' to use # HTTPS. This is no longer true. # # === Proxies # # Net::HTTP will automatically create a proxy from the +http_proxy+ # environment variable if it is present. To disable use of +http_proxy+, # pass +nil+ for the proxy address. # # You may also create a custom proxy: # # proxy_addr = 'your.proxy.host' # proxy_port = 8080 # # Net::HTTP.new('example.com', nil, proxy_addr, proxy_port).start { |http| # # always proxy via your.proxy.addr:8080 # } # # See Net::HTTP.new for further details and examples such as proxies that # require a username and password. # # === Compression # # Net::HTTP automatically adds Accept-Encoding for compression of response # bodies and automatically decompresses gzip and deflate responses unless a # Range header was sent. # # Compression can be disabled through the Accept-Encoding: identity header. # # == HTTP Request Classes # # Here is the HTTP request class hierarchy. # # * Net::HTTPRequest # * Net::HTTP::Get # * Net::HTTP::Head # * Net::HTTP::Post # * Net::HTTP::Patch # * Net::HTTP::Put # * Net::HTTP::Proppatch # * Net::HTTP::Lock # * Net::HTTP::Unlock # * Net::HTTP::Options # * Net::HTTP::Propfind # * Net::HTTP::Delete # * Net::HTTP::Move # * Net::HTTP::Copy # * Net::HTTP::Mkcol # * Net::HTTP::Trace # # == HTTP Response Classes # # Here is HTTP response class hierarchy.

Berger with suggestions from Florian Gross. # # Documentation by James Edward Gray II and Gavin Sinclair # The Forwardable module provides delegation of specified # methods to a designated object, using the methods #def_delegator # and #def_delegators. # # For example, say you have a class RecordCollection which # contains an array <tt>@records</tt>. You could provide the lookup method # #record_number(), which simply calls #[] on the <tt>@records</tt> # array, like this: # # require 'forwardable' # # class RecordCollection # attr_accessor :records # extend Forwardable # def_delegator :@records, :[], :record_number # end # # We can use the lookup method like so: # # r = RecordCollection.new # r.records = [4,5,6] # r.record_number(0) # => 4 # # Further, if you wish to provide the methods #size, #<<, and #map, # all of which delegate to @records, this is how you can do it: # # class RecordCollection # re-open RecordCollection class # def_delegators :@records, :size, :<<, :map # end # # r = RecordCollection.new # r.records = [1,2,3] # r.record_number(0) # => 1 # r.size # => 3 # r << 4 # => [1, 2, 3, 4] # r.map { |x| x * 2 } # => [2, 4, 6, 8] # # You can even extend regular objects with Forwardable. # # my_hash = Hash.new # my_hash.extend Forwardable # prepare object for delegation # my_hash.def_delegator "STDOUT", "puts" # add delegation for STDOUT.puts() # my_hash.puts "Howdy!" # # == Another example # # You could use Forwardable as an alternative to inheritance, when you don't want # to inherit all methods from the superclass. For instance, here is how you might # add a range of +Array+ instance methods to a new class +Queue+: # # class Queue # extend Forwardable # # def initialize # @q = [ ] # prepare delegate object # end # # # setup preferred interface, enq() and deq()... # def_delegator :@q, :push, :enq # def_delegator :@q, :shift, :deq # # # support some general Array methods that fit Queues well # def_delegators :@q, :clear, :first, :push, :shift, :size # end # # q = Queue.new # q.enq 1, 2, 3, 4, 5 # q.push 6 # # q.shift # => 1 # while q.size > 0 # puts q.deq # end # # q.enq "Ruby", "Perl", "Python" # puts q.first # q.clear # puts q.first # # This should output: # # 2 # 3 # 4 # 5 # 6 # Ruby # nil # # == Notes # # Be advised, RDoc will not detect delegated methods. # # +forwardable.rb+ provides single-method delegation via the def_delegator and # def_delegators methods.

It is written in # pure Ruby and uses its own protocol. No add-in services are needed # beyond those provided by the Ruby runtime, such as TCP sockets. It # does not rely on or interoperate with other distributed object # systems such as CORBA, RMI, or .NET. # # dRuby allows methods to be called in one Ruby process upon a Ruby # object located in another Ruby process, even on another machine. # References to objects can be passed between processes. Method # arguments and return values are dumped and loaded in marshalled # format. All of this is done transparently to both the caller of the # remote method and the object that it is called upon. # # An object in a remote process is locally represented by a # DRb::DRbObject instance. This acts as a sort of proxy for the # remote object. Methods called upon this DRbObject instance are # forwarded to its remote object. This is arranged dynamically at run # time. There are no statically declared interfaces for remote # objects, such as CORBA's IDL. # # dRuby calls made into a process are handled by a DRb::DRbServer # instance within that process. This reconstitutes the method call, # invokes it upon the specified local object, and returns the value to # the remote caller. Any object can receive calls over dRuby. There # is no need to implement a special interface, or mixin special # functionality. Nor, in the general case, does an object need to # explicitly register itself with a DRbServer in order to receive # dRuby calls. # # One process wishing to make dRuby calls upon another process must # somehow obtain an initial reference to an object in the remote # process by some means other than as the return value of a remote # method call, as there is initially no remote object reference it can # invoke a method upon. This is done by attaching to the server by # URI. Each DRbServer binds itself to a URI such as # 'druby://example.com:8787'. A DRbServer can have an object attached # to it that acts as the server's *front* *object*. A DRbObject can # be explicitly created from the server's URI. This DRbObject's # remote object will be the server's front object. This front object # can then return references to other Ruby objects in the DRbServer's # process. # # Method calls made over dRuby behave largely the same as normal Ruby # method calls made within a process. Method calls with blocks are # supported, as are raising exceptions. In addition to a method's # standard errors, a dRuby call may also raise one of the # dRuby-specific errors, all of which are subclasses of DRb::DRbError. # # Any type of object can be passed as an argument to a dRuby call or # returned as its return value. By default, such objects are dumped # or marshalled at the local end, then loaded or unmarshalled at the # remote end. The remote end therefore receives a copy of the local # object, not a distributed reference to it; methods invoked upon this # copy are executed entirely in the remote process, not passed on to # the local original. This has semantics similar to pass-by-value. # # However, if an object cannot be marshalled, a dRuby reference to it # is passed or returned instead. This will turn up at the remote end # as a DRbObject instance. All methods invoked upon this remote proxy # are forwarded to the local object, as described in the discussion of # DRbObjects. This has semantics similar to the normal Ruby # pass-by-reference. # # The easiest way to signal that we want an otherwise marshallable # object to be passed or returned as a DRbObject reference, rather # than marshalled and sent as a copy, is to include the # DRb::DRbUndumped mixin module. # # dRuby supports calling remote methods with blocks. As blocks (or # rather the Proc objects that represent them) are not marshallable, # the block executes in the local, not the remote, context. Each # value yielded to the block is passed from the remote object to the # local block, then the value returned by each block invocation is # passed back to the remote execution context to be collected, before # the collected values are finally returned to the local context as # the return value of the method invocation. # # == Examples of usage # # For more dRuby samples, see the +samples+ directory in the full # dRuby distribution. # # === dRuby in client/server mode # # This illustrates setting up a simple client-server drb # system. Run the server and client code in different terminals, # starting the server code first. # # ==== Server code # # require 'drb/drb' # # # The URI for the server to connect to # URI="druby://localhost:8787" # # class TimeServer # # def get_current_time # return Time.now # end # # end # # # The object that handles requests on the server # FRONT_OBJECT=TimeServer.new # # DRb.start_service(URI, FRONT_OBJECT) # # Wait for the drb server thread to finish before exiting. # DRb.thread.join # # ==== Client code # # require 'drb/drb' # # # The URI to connect to # SERVER_URI="druby://localhost:8787" # # # Start a local DRbServer to handle callbacks. # # # # Not necessary for this small example, but will be required # # as soon as we pass a non-marshallable object as an argument # # to a dRuby call. # # # # Note: this must be called at least once per process to take any effect. # # This is particularly important if your application forks. # DRb.start_service # # timeserver = DRbObject.new_with_uri(SERVER_URI) # puts timeserver.get_current_time # # === Remote objects under dRuby # # This example illustrates returning a reference to an object # from a dRuby call. The Logger instances live in the server # process. References to them are returned to the client process, # where methods can be invoked upon them. These methods are # executed in the server process. # # ==== Server code # # require 'drb/drb' # # URI="druby://localhost:8787" # # class Logger # # # Make dRuby send Logger instances as dRuby references, # # not copies. # include DRb::DRbUndumped # # def initialize(n, fname) # @name = n # @filename = fname # end # # def log(message) # File.open(@filename, "a") do |f| # f.puts("#{Time.now}: #{@name}: #{message}") # end # end # # end # # # We have a central object for creating and retrieving loggers. # # This retains a local reference to all loggers created.

By allowing external access to a Ruby object, you are # not only allowing outside clients to call the methods you have # defined for that object, but by default to execute arbitrary Ruby # code on your server. Consider the following: # # # !!! UNSAFE CODE !!! # ro = DRbObject::new_with_uri("druby://your.server.com:8989") # class << ro # undef :instance_eval # force call to be passed to remote object # end # ro.instance_eval("`rm -rf *`") # # The dangers posed by instance_eval and friends are such that a # DRbServer should only be used when clients are trusted. # # A DRbServer can be configured with an access control list to # selectively allow or deny access from specified IP addresses. The # main druby distribution provides the ACL class for this purpose. In # general, this mechanism should only be used alongside, rather than # as a replacement for, a good firewall. # # == dRuby internals # # dRuby is implemented using three main components: a remote method # call marshaller/unmarshaller; a transport protocol; and an # ID-to-object mapper. The latter two can be directly, and the first # indirectly, replaced, in order to provide different behaviour and # capabilities. # # Marshalling and unmarshalling of remote method calls is performed by # a DRb::DRbMessage instance. This uses the Marshal module to dump # the method call before sending it over the transport layer, then # reconstitute it at the other end. There is normally no need to # replace this component, and no direct way is provided to do so. # However, it is possible to implement an alternative marshalling # scheme as part of an implementation of the transport layer. # # The transport layer is responsible for opening client and server # network connections and forwarding dRuby request across them. # Normally, it uses DRb::DRbMessage internally to manage marshalling # and unmarshalling. The transport layer is managed by # DRb::DRbProtocol. Multiple protocols can be installed in # DRbProtocol at the one time; selection between them is determined by # the scheme of a dRuby URI. The default transport protocol is # selected by the scheme 'druby:', and implemented by # DRb::DRbTCPSocket. This uses plain TCP/IP sockets for # communication. An alternative protocol, using UNIX domain sockets, # is implemented by DRb::DRbUNIXSocket in the file drb/unix.rb, and # selected by the scheme 'drbunix:'. A sample implementation over # HTTP can be found in the samples accompanying the main dRuby # distribution. # # The ID-to-object mapping component maps dRuby object ids to the # objects they refer to, and vice versa. The implementation to use # can be specified as part of a DRb::DRbServer's configuration. The # default implementation is provided by DRb::DRbIdConv. It uses an # object's ObjectSpace id as its dRuby id. This means that the dRuby # reference to that object only remains meaningful for the lifetime of # the object's process and the lifetime of the object within that # process. A modified implementation is provided by DRb::TimerIdConv # in the file drb/timeridconv.rb. This implementation retains a local # reference to all objects exported over dRuby for a configurable # period of time (defaulting to ten minutes), to prevent them being # garbage-collected within this time. Another sample implementation # is provided in sample/name.rb in the main dRuby distribution. This # allows objects to specify their own id or "name". A dRuby reference # can be made persistent across processes by having each process # register an object using the same dRuby name. # module DRb # Superclass of all errors raised in the DRb module. class DRbError < RuntimeError; end # Error raised when an error occurs on the underlying communication # protocol. class DRbConnError < DRbError; end # Class responsible for converting between an object and its id. # # This, the default implementation, uses an object's local ObjectSpace # __id__ as its id.

This is most easily implemented by calling # DRb.recv_reply, providing a stream that sits on top of the # current protocol. # [alive?] # Is this connection still alive? # [close] # Close this connection. # # The protocol instance returned by #open_server().accept() must have # the following methods: # # [recv_request] # Receive a request from the client and return a [object, message, # args, block] tuple. This is most easily implemented by calling # DRbMessage.recv_request, providing a stream that sits on top of # the current protocol. # [send_reply(succ, result)] # Send a reply to the client. This is most easily implemented # by calling DRbMessage.send_reply, providing a stream that sits # on top of the current protocol. # [close] # Close this connection. # # A new protocol is registered with the DRbProtocol module using # the add_protocol method. # # For examples of other protocols, see DRbUNIXSocket in drb/unix.rb, # and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full # drb distribution. module DRbProtocol # Add a new protocol to the DRbProtocol module. def add_protocol(prot) @protocol.push(prot) end module_function :add_protocol # Open a client connection to +uri+ with the configuration +config+. # # The DRbProtocol module asks each registered protocol in turn to # try to open the URI.

You can redistribute and/or modify it under the same # terms as Ruby. ## # This library provides the Set class, which deals with a collection # of unordered values with no duplicates. It is a hybrid of Array's # intuitive inter-operation facilities and Hash's fast lookup. # # The method `to_set` is added to Enumerable for convenience. # # Set implements a collection of unordered values with no duplicates. # This is a hybrid of Array's intuitive inter-operation facilities and # Hash's fast lookup. # # Set is easy to use with Enumerable objects (implementing `each`). # Most of the initializer methods and binary operators accept generic # Enumerable objects besides sets and arrays. An Enumerable object # can be converted to Set using the `to_set` method. # # Set uses Hash as storage, so you must note the following points: # # * Equality of elements is determined according to Object#eql? and # Object#hash. Use Set#compare_by_identity to make a set compare # its elements by their identity. # * Set assumes that the identity of each element does not change # while it is stored. Modifying an element of a set will render the # set to an unreliable state. # * When a string is to be stored, a frozen copy of the string is # stored instead unless the original string is already frozen. # # ## Comparison # # The comparison operators `<`, `>`, `<=`, and `>=` are implemented as # shorthand for the {proper_,}{subset?,superset?} methods. The `<=>` # operator reflects this order, or return `nil` for sets that both # have distinct elements (`{x, y}` vs. `{x, z}` for example). # # ## Example # # ```ruby # require 'set' # s1 = Set[1, 2] #=> #<Set: {1, 2}> # s2 = [1, 2].to_set #=> #<Set: {1, 2}> # s1 == s2 #=> true # s1.add("foo") #=> #<Set: {1, 2, "foo"}> # s1.merge([2, 6]) #=> #<Set: {1, 2, "foo", 6}> # s1.subset?(s2) #=> false # s2.subset?(s1) #=> true # ``` # # ## Contact # # - Akinori MUSHA <<knu@iDaemons.org>> (current maintainer) # class Set include Enumerable # Creates a new set containing the given objects. # # Set[1, 2] # => #<Set: {1, 2}> # Set[1, 2, 1] # => #<Set: {1, 2}> # Set[1, 'c', :s] # => #<Set: {1, "c", :s}> def self.[](*ary) new(ary) end # Creates a new set containing the elements of the given enumerable # object. # # If a block is given, the elements of enum are preprocessed by the # given block. # # Set.new([1, 2]) #=> #<Set: {1, 2}> # Set.new([1, 2, 1]) #=> #<Set: {1, 2}> # Set.new([1, 'c', :s]) #=> #<Set: {1, "c", :s}> # Set.new(1..5) #=> #<Set: {1, 2, 3, 4, 5}> # Set.new([1, 2, 3]) { |x| x * x } #=> #<Set: {1, 4, 9}> def initialize(enum = nil, &block) # :yields: o @hash ||= Hash.new(false) enum.nil? and return if block do_with_enum(enum) { |o| add(block[o]) } else merge(enum) end end # Makes the set compare its elements by their identity and returns # self.

FasterCSV was # intended as a replacement to Ruby's then standard CSV library. It was # designed to address concerns users of that library had and it had three # primary goals: # # 1. Be significantly faster than CSV while remaining a pure Ruby library. # 2. Use a smaller and easier to maintain code base. (FasterCSV eventually # grew larger, was also but considerably richer in features. The parsing # core remains quite small.) # 3. Improve on the CSV interface. # # Obviously, the last one is subjective. I did try to defer to the original # interface whenever I didn't have a compelling reason to change it though, so # hopefully this won't be too radically different. # # We must have met our goals because FasterCSV was renamed to CSV and replaced # the original library as of Ruby 1.9. If you are migrating code from 1.8 or # earlier, you may have to change your code to comply with the new interface. # # == What's the Different From the Old CSV? # # I'm sure I'll miss something, but I'll try to mention most of the major # differences I am aware of, to help others quickly get up to speed: # # === \CSV Parsing # # * This parser is m17n aware. See CSV for full details. # * This library has a stricter parser and will throw MalformedCSVErrors on # problematic data. # * This library has a less liberal idea of a line ending than CSV. What you # set as the <tt>:row_sep</tt> is law. It can auto-detect your line endings # though. # * The old library returned empty lines as <tt>[nil]</tt>. This library calls # them <tt>[]</tt>. # * This library has a much faster parser. # # === Interface # # * CSV now uses Hash-style parameters to set options. # * CSV no longer has generate_row() or parse_row(). # * The old CSV's Reader and Writer classes have been dropped. # * CSV::open() is now more like Ruby's open(). # * CSV objects now support most standard IO methods. # * CSV now has a new() method used to wrap objects like String and IO for # reading and writing. # * CSV::generate() is different from the old method. # * CSV no longer supports partial reads. It works line-by-line. # * CSV no longer allows the instance methods to override the separators for # performance reasons. They must be set in the constructor. # # If you use this library and find yourself missing any functionality I have # trimmed, please {let me know}[mailto:james@grayproductions.net]. # # == Documentation # # See CSV for documentation. # # == What is CSV, really? # # CSV maintains a pretty strict definition of CSV taken directly from # {the RFC}[http://www.ietf.org/rfc/rfc4180.txt]. I relax the rules in only one # place and that is to make using this library easier. CSV will parse all valid # CSV. # # What you don't want to do is to feed CSV invalid data. Because of the way the # CSV format works, it's common for a parser to need to read until the end of # the file to be sure a field is invalid. This consumes a lot of time and memory. # # Luckily, when working with invalid CSV, Ruby's built-in methods will almost # always be superior in every way. For example, parsing non-quoted fields is as # easy as: # # data.split(",") # # == Questions and/or Comments # # Feel free to email {James Edward Gray II}[mailto:james@grayproductions.net] # with any questions. require "forwardable" require "English" require "date" require "stringio" require_relative "csv/fields_converter" require_relative "csv/match_p" require_relative "csv/parser" require_relative "csv/row" require_relative "csv/table" require_relative "csv/writer" using CSV::MatchP if CSV.const_defined?(:MatchP) # == \CSV # \CSV (comma-separated variables) data is a text representation of a table: # - A _row_ _separator_ delimits table rows. # A common row separator is the newline character <tt>"\n"</tt>. # - A _column_ _separator_ delimits fields in a row. # A common column separator is the comma character <tt>","</tt>. # # This \CSV \String, with row separator <tt>"\n"</tt> # and column separator <tt>","</tt>, # has three rows and two columns: # "foo,0\nbar,1\nbaz,2\n" # # Despite the name \CSV, a \CSV representation can use different separators. # # For more about tables, see the Wikipedia article # "{Table (information)}[https://en.wikipedia.org/wiki/Table_(information)]", # especially its section # "{Simple table}[https://en.wikipedia.org/wiki/Table_(information)#Simple_table]" # # == \Class \CSV # # Class \CSV provides methods for: # - Parsing \CSV data from a \String object, a \File (via its file path), or an \IO object. # - Generating \CSV data to a \String object. # # To make \CSV available: # require 'csv' # # All examples here assume that this has been done. # # == Keeping It Simple # # A \CSV object has dozens of instance methods that offer fine-grained control # of parsing and generating \CSV data. # For many needs, though, simpler approaches will do. # # This section summarizes the singleton methods in \CSV # that allow you to parse and generate without explicitly # creating \CSV objects. # For details, follow the links. # # === Simple Parsing # # Parsing methods commonly return either of: # - An \Array of Arrays of Strings: # - The outer \Array is the entire "table". # - Each inner \Array is a row. # - Each \String is a field. # - A CSV::Table object. For details, see # {\CSV with Headers}[#class-CSV-label-CSV+with+Headers]. # # ==== Parsing a \String # # The input to be parsed can be a string: # string = "foo,0\nbar,1\nbaz,2\n" # # \Method CSV.parse returns the entire \CSV data: # CSV.parse(string) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # \Method CSV.parse_line returns only the first row: # CSV.parse_line(string) # => ["foo", "0"] # # \CSV extends class \String with instance method String#parse_csv, # which also returns only the first row: # string.parse_csv # => ["foo", "0"] # # ==== Parsing Via a \File Path # # The input to be parsed can be in a file: # string = "foo,0\nbar,1\nbaz,2\n" # path = 't.csv' # File.write(path, string) # # \Method CSV.read returns the entire \CSV data: # CSV.read(path) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # \Method CSV.foreach iterates, passing each row to the given block: # CSV.foreach(path) do |row| # p row # end # Output: # ["foo", "0"] # ["bar", "1"] # ["baz", "2"] # # \Method CSV.table returns the entire \CSV data as a CSV::Table object: # CSV.table(path) # => #<CSV::Table mode:col_or_row row_count:3> # # ==== Parsing from an Open \IO Stream # # The input to be parsed can be in an open \IO stream: # # \Method CSV.read returns the entire \CSV data: # File.open(path) do |file| # CSV.read(file) # end # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # As does method CSV.parse: # File.open(path) do |file| # CSV.parse(file) # end # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # \Method CSV.parse_line returns only the first row: # File.open(path) do |file| # CSV.parse_line(file) # end # => ["foo", "0"] # # \Method CSV.foreach iterates, passing each row to the given block: # File.open(path) do |file| # CSV.foreach(file) do |row| # p row # end # end # Output: # ["foo", "0"] # ["bar", "1"] # ["baz", "2"] # # \Method CSV.table returns the entire \CSV data as a CSV::Table object: # File.open(path) do |file| # CSV.table(file) # end # => #<CSV::Table mode:col_or_row row_count:3> # # === Simple Generating # # \Method CSV.generate returns a \String; # this example uses method CSV#<< to append the rows # that are to be generated: # output_string = CSV.generate do |csv| # csv << ['foo', 0] # csv << ['bar', 1] # csv << ['baz', 2] # end # output_string # => "foo,0\nbar,1\nbaz,2\n" # # \Method CSV.generate_line returns a \String containing the single row # constructed from an \Array: # CSV.generate_line(['foo', '0']) # => "foo,0\n" # # \CSV extends class \Array with instance method <tt>Array#to_csv</tt>, # which forms an \Array into a \String: # ['foo', '0'].to_csv # => "foo,0\n" # # === "Filtering" \CSV # # \Method CSV.filter provides a Unix-style filter for \CSV data. # The input data is processed to form the output data: # in_string = "foo,0\nbar,1\nbaz,2\n" # out_string = '' # CSV.filter(in_string, out_string) do |row| # row[0] = row[0].upcase # row[1] *= 4 # end # out_string # => "FOO,0000\nBAR,1111\nBAZ,2222\n" # # == \CSV Objects # # There are three ways to create a \CSV object: # - \Method CSV.new returns a new \CSV object. # - \Method CSV.instance returns a new or cached \CSV object. # - \Method \CSV() also returns a new or cached \CSV object. # # === Instance Methods # # \CSV has three groups of instance methods: # - Its own internally defined instance methods. # - Methods included by module Enumerable. # - Methods delegated to class IO.

See {Field Converters}[#class-CSV-label-Field+Converters]. # - See {Header Converters}[#class-CSV-label-Header+Converters]. # # Also by default, each value to be written during generation is written 'as-is'. # You can use a _write_ _converter_ to modify values before writing. # - See {Write Converters}[#class-CSV-label-Write+Converters]. # # ==== Specifying \Converters # # You can specify converters for parsing or generating in the +options+ # argument to various \CSV methods: # - Option +converters+ for converting parsed field values. # - Option +header_converters+ for converting parsed header values. # - Option +write_converters+ for converting values to be written (generated). # # There are three forms for specifying converters: # - A converter proc: executable code to be used for conversion. # - A converter name: the name of a stored converter. # - A converter list: an array of converter procs, converter names, and converter lists. # # ===== Converter Procs # # This converter proc, +strip_converter+, accepts a value +field+ # and returns <tt>field.strip</tt>: # strip_converter = proc {|field| field.strip } # In this call to <tt>CSV.parse</tt>, # the keyword argument <tt>converters: string_converter</tt> # specifies that: # - \Proc +string_converter+ is to be called for each parsed field. # - The converter's return value is to replace the +field+ value. # Example: # string = " foo , 0 \n bar , 1 \n baz , 2 \n" # array = CSV.parse(string, converters: strip_converter) # array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # A converter proc can receive a second argument, +field_info+, # that contains details about the field. # This modified +strip_converter+ displays its arguments: # strip_converter = proc do |field, field_info| # p [field, field_info] # field.strip # end # string = " foo , 0 \n bar , 1 \n baz , 2 \n" # array = CSV.parse(string, converters: strip_converter) # array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # Output: # [" foo ", #<struct CSV::FieldInfo index=0, line=1, header=nil>] # [" 0 ", #<struct CSV::FieldInfo index=1, line=1, header=nil>] # [" bar ", #<struct CSV::FieldInfo index=0, line=2, header=nil>] # [" 1 ", #<struct CSV::FieldInfo index=1, line=2, header=nil>] # [" baz ", #<struct CSV::FieldInfo index=0, line=3, header=nil>] # [" 2 ", #<struct CSV::FieldInfo index=1, line=3, header=nil>] # Each CSV::Info object shows: # - The 0-based field index. # - The 1-based line index. # - The field header, if any. # # ===== Stored \Converters # # A converter may be given a name and stored in a structure where # the parsing methods can find it by name. # # The storage structure for field converters is the \Hash CSV::Converters. # It has several built-in converter procs: # - <tt>:integer</tt>: converts each \String-embedded integer into a true \Integer. # - <tt>:float</tt>: converts each \String-embedded float into a true \Float. # - <tt>:date</tt>: converts each \String-embedded date into a true \Date. # - <tt>:date_time</tt>: converts each \String-embedded date-time into a true \DateTime # . # This example creates a converter proc, then stores it: # strip_converter = proc {|field| field.strip } # CSV::Converters[:strip] = strip_converter # Then the parsing method call can refer to the converter # by its name, <tt>:strip</tt>: # string = " foo , 0 \n bar , 1 \n baz , 2 \n" # array = CSV.parse(string, converters: :strip) # array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # The storage structure for header converters is the \Hash CSV::HeaderConverters, # which works in the same way. # It also has built-in converter procs: # - <tt>:downcase</tt>: Downcases each header. # - <tt>:symbol</tt>: Converts each header to a \Symbol. # # There is no such storage structure for write headers. # # ===== Converter Lists # # A _converter_ _list_ is an \Array that may include any assortment of: # - Converter procs. # - Names of stored converters. # - Nested converter lists. # # Examples: # numeric_converters = [:integer, :float] # date_converters = [:date, :date_time] # [numeric_converters, strip_converter] # [strip_converter, date_converters, :float] # # Like a converter proc, a converter list may be named and stored in either # \CSV::Converters or CSV::HeaderConverters: # CSV::Converters[:custom] = [strip_converter, date_converters, :float] # CSV::HeaderConverters[:custom] = [:downcase, :symbol] # # There are two built-in converter lists: # CSV::Converters[:numeric] # => [:integer, :float] # CSV::Converters[:all] # => [:date_time, :numeric] # # ==== Field \Converters # # With no conversion, all parsed fields in all rows become Strings: # string = "foo,0\nbar,1\nbaz,2\n" # ary = CSV.parse(string) # ary # => # => [["foo", "0"], ["bar", "1"], ["baz", "2"]] # # When you specify a field converter, each parsed field is passed to the converter; # its return value becomes the stored value for the field. # A converter might, for example, convert an integer embedded in a \String # into a true \Integer. # (In fact, that's what built-in field converter +:integer+ does.) # # There are three ways to use field \converters. # # - Using option {converters}[#class-CSV-label-Option+converters] with a parsing method: # ary = CSV.parse(string, converters: :integer) # ary # => [0, 1, 2] # => [["foo", 0], ["bar", 1], ["baz", 2]] # -

The parser works in the Encoding of the IO # or String object being read from or written to. Your data is never transcoded # (unless you ask Ruby to transcode it for you) and will literally be parsed in # the Encoding it is in. Thus CSV will return Arrays or Rows of Strings in the # Encoding of your data. This is accomplished by transcoding the parser itself # into your Encoding. # # Some transcoding must take place, of course, to accomplish this multiencoding # support. For example, <tt>:col_sep</tt>, <tt>:row_sep</tt>, and # <tt>:quote_char</tt> must be transcoded to match your data. Hopefully this # makes the entire process feel transparent, since CSV's defaults should just # magically work for your data. However, you can set these values manually in # the target Encoding to avoid the translation. # # It's also important to note that while all of CSV's core parser is now # Encoding agnostic, some features are not. For example, the built-in # converters will try to transcode data to UTF-8 before making conversions. # Again, you can provide custom converters that are aware of your Encodings to # avoid this translation. It's just too hard for me to support native # conversions in all of Ruby's Encodings. # # Anyway, the practical side of this is simple: make sure IO and String objects # passed into CSV have the proper Encoding set and everything should just work. # CSV methods that allow you to open IO objects (CSV::foreach(), CSV::open(), # CSV::read(), and CSV::readlines()) do allow you to specify the Encoding. # # One minor exception comes when generating CSV into a String with an Encoding # that is not ASCII compatible. There's no existing data for CSV to use to # prepare itself and thus you will probably need to manually specify the desired # Encoding for most of those cases. It will try to guess using the fields in a # row of output though, when using CSV::generate_line() or Array#to_csv(). # # I try to point out any other Encoding issues in the documentation of methods # as they come up. # # This has been tested to the best of my ability with all non-"dummy" Encodings # Ruby ships with. However, it is brave new code and may have some bugs. # Please feel free to {report}[mailto:james@grayproductions.net] any issues you # find with it. # class CSV # The error thrown when the parser encounters illegal CSV formatting. class MalformedCSVError < RuntimeError attr_reader :line_number alias_method :lineno, :line_number def initialize(message, line_number) @line_number = line_number super("#{message} in line #{line_number}.") end end # # A FieldInfo Struct contains details about a field's position in the data # source it was read from.

Here, we're treating each key in # the hash as a node in the graph, and so we simply alias the required # #tsort_each_node method to Hash's #each_key method. For each key in the # hash, the associated value is an array of the node's child nodes. This # choice in turn leads to our implementation of the required #tsort_each_child # method, which fetches the array of child nodes and then iterates over that # array using the user-supplied block. # # require 'tsort' # # class Hash # include TSort # alias tsort_each_node each_key # def tsort_each_child(node, &block) # fetch(node).each(&block) # end # end # # {1=>[2, 3], 2=>[3], 3=>[], 4=>[]}.tsort # #=> [3, 2, 1, 4] # # {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components # #=> [[4], [2, 3], [1]] # # == A More Realistic Example # # A very simple `make' like tool can be implemented as follows: # # require 'tsort' # # class Make # def initialize # @dep = {} # @dep.default = [] # end # # def rule(outputs, inputs=[], &block) # triple = [outputs, inputs, block] # outputs.each {|f| @dep[f] = [triple]} # @dep[triple] = inputs # end # # def build(target) # each_strongly_connected_component_from(target) {|ns| # if ns.length != 1 # fs = ns.delete_if {|n| Array === n} # raise TSort::Cyclic.new("cyclic dependencies: #{fs.join ', '}") # end # n = ns.first # if Array === n # outputs, inputs, block = n # inputs_time = inputs.map {|f| File.mtime f}.max # begin # outputs_time = outputs.map {|f| File.mtime f}.min # rescue Errno::ENOENT # outputs_time = nil # end # if outputs_time == nil || # inputs_time != nil && outputs_time <= inputs_time # sleep 1 if inputs_time != nil && inputs_time.to_i == Time.now.to_i # block.call # end # end # } # end # # def tsort_each_child(node, &block) # @dep[node].each(&block) # end # include TSort # end # # def command(arg) # print arg, "\n" # system arg # end # # m = Make.new # m.rule(%w[t1]) { command 'date > t1' } # m.rule(%w[t2]) { command 'date > t2' } # m.rule(%w[t3]) { command 'date > t3' } # m.rule(%w[t4], %w[t1 t3]) { command 'cat t1 t3 > t4' } # m.rule(%w[t5], %w[t4 t2]) { command 'cat t4 t2 > t5' } # m.build('t5') # # == Bugs # # * 'tsort.rb' is wrong name because this library uses # Tarjan's algorithm for strongly connected components. # Although 'strongly_connected_components.rb' is correct but too long. # # == References # # R.

The easiest to use is SimpleDelegator. Pass an object to the # constructor and all methods supported by the object will be delegated. This # object can be changed later. # # Going a step further, the top level DelegateClass method allows you to easily # setup delegation through class inheritance. This is considerably more # flexible and thus probably the most common use for this library. # # Finally, if you need full control over the delegation scheme, you can inherit # from the abstract class Delegator and customize as needed. (If you find # yourself needing this control, have a look at Forwardable which is also in # the standard library. It may suit your needs better.) # # SimpleDelegator's implementation serves as a nice example of the use of # Delegator: # # require 'delegate' # # class SimpleDelegator < Delegator # def __getobj__ # @delegate_sd_obj # return object we are delegating to, required # end # # def __setobj__(obj) # @delegate_sd_obj = obj # change delegation object, # # a feature we're providing # end # end # # == Notes # # Be advised, RDoc will not detect delegated methods. # class Delegator < BasicObject VERSION = "0.2.0" kernel = ::Kernel.dup kernel.class_eval do alias __raise__ raise [:to_s, :inspect, :=~, :!~, :===, :<=>, :hash].each do |m| undef_method m end private_instance_methods.each do |m| if /\Ablock_given\?\z|\Aiterator\?\z|\A__.*__\z/ =~ m next end undef_method m end end include kernel # :stopdoc: def self.const_missing(n) ::Object.const_get(n) end # :startdoc: ## # :method: raise # Use #__raise__ if your Delegator does not have a object to delegate the # #raise method call. # # # Pass in the _obj_ to delegate method calls to.

The # following documentation is copied, with modifications, from "Programming # Ruby", by Hunt and Thomas; http://www.ruby-doc.org/docs/ProgrammingRuby/html/lib_patterns.html. # # See Observable for more info. # The Observer pattern (also known as publish/subscribe) provides a simple # mechanism for one object to inform a set of interested third-party objects # when its state changes. # # == Mechanism # # The notifying class mixes in the +Observable+ # module, which provides the methods for managing the associated observer # objects. # # The observable object must: # * assert that it has +#changed+ # * call +#notify_observers+ # # An observer subscribes to updates using Observable#add_observer, which also # specifies the method called via #notify_observers. The default method for # #notify_observers is #update. # # === Example # # The following example demonstrates this nicely. A +Ticker+, when run, # continually receives the stock +Price+ for its <tt>@symbol</tt>. A +Warner+ # is a general observer of the price, and two warners are demonstrated, a # +WarnLow+ and a +WarnHigh+, which print a warning if the price is below or # above their set limits, respectively. # # The +update+ callback allows the warners to run without being explicitly # called. The system is set up with the +Ticker+ and several observers, and the # observers do their duty without the top-level code having to interfere. # # Note that the contract between publisher and subscriber (observable and # observer) is not declared or enforced. The +Ticker+ publishes a time and a # price, and the warners receive that. But if you don't ensure that your # contracts are correct, nothing else can warn you. # # require "observer" # # class Ticker ### Periodically fetch a stock price. # include Observable # # def initialize(symbol) # @symbol = symbol # end # # def run # last_price = nil # loop do # price = Price.fetch(@symbol) # print "Current price: #{price}\n" # if price != last_price # changed # notify observers # last_price = price # notify_observers(Time.now, price) # end # sleep 1 # end # end # end # # class Price ### A mock class to fetch a stock price (60 - 140). # def self.fetch(symbol) # 60 + rand(80) # end # end # # class Warner ### An abstract observer of Ticker objects. # def initialize(ticker, limit) # @limit = limit # ticker.add_observer(self) # end # end # # class WarnLow < Warner # def update(time, price) # callback for observer # if price < @limit # print "--- #{time.to_s}: Price below #@limit: #{price}\n" # end # end # end # # class WarnHigh < Warner # def update(time, price) # callback for observer # if price > @limit # print "+++ #{time.to_s}: Price above #@limit: #{price}\n" # end # end # end # # ticker = Ticker.new("MSFT") # WarnLow.new(ticker, 80) # WarnHigh.new(ticker, 120) # ticker.run # # Produces: # # Current price: 83 # Current price: 75 # --- Sun Jun 09 00:10:25 CDT 2002: Price below 80: 75 # Current price: 90 # Current price: 134 # +++ Sun Jun 09 00:10:25 CDT 2002: Price above 120: 134 # Current price: 134 # Current price: 112 # Current price: 79 # --- Sun Jun 09 00:10:25 CDT 2002: Price below 80: 79 # # === Usage with procs # # The +#notify_observers+ method can also be used with +proc+s by using # the +:call+ as +func+ parameter. # # The following example illustrates the use of a lambda: # # require 'observer' # # class Ticker # include Observable # # def run # # logic to retrieve the price (here 77.0) # changed # notify_observers(77.0) # end # end # # ticker = Ticker.new # warner = ->(price) { puts "New price received: #{price}" } # ticker.add_observer(warner, :call) # ticker.run module Observable VERSION = "0.1.1" # # Add +observer+ as an observer on this object.

This is accomplished through the methods # method_missing and define_singleton_method. # # This should be a consideration if there is a concern about the performance of # the objects that are created, as there is much more overhead in the setting # of these properties compared to using a Hash or a Struct. # Creating an open struct from a small Hash and accessing a few of the # entries can be 200 times slower than accessing the hash directly. # # This is a potential security issue; building OpenStruct from untrusted user data # (e.g. JSON web request) may be susceptible to a "symbol denial of service" attack # since the keys create methods and names of methods are never garbage collected. # # This may also be the source of incompatibilities between Ruby versions: # # o = OpenStruct.new # o.then # => nil in Ruby < 2.6, enumerator for Ruby >= 2.6 # # Builtin methods may be overwritten this way, which may be a source of bugs # or security issues: # # o = OpenStruct.new # o.methods # => [:to_h, :marshal_load, :marshal_dump, :each_pair, ... # o.methods = [:foo, :bar] # o.methods # => [:foo, :bar] # # To help remedy clashes, OpenStruct uses only protected/private methods ending with `!` # and defines aliases for builtin public methods by adding a `!`: # # o = OpenStruct.new(make: 'Bentley', class: :luxury) # o.class # => :luxury # o.class! # => OpenStruct # # It is recommended (but not enforced) to not use fields ending in `!`; # Note that a subclass' methods may not be overwritten, nor can OpenStruct's own methods # ending with `!`. # # For all these reasons, consider not using OpenStruct at all. # class OpenStruct VERSION = "0.3.1" # # Creates a new OpenStruct object.

You can do that by pressing +n+: # # (rdb:1) n # goes to next line # (rdb:1) p foo # nil # # You now know that the original value of +foo+ was nil, and that it # still was nil after calling +get_foo+. # # Other useful commands for navigating through your code are: # # +c+:: # Runs the program until it either exists or encounters another breakpoint. # You usually press +c+ when you are finished debugging your program and # want to resume its execution. # +s+:: # Steps into method definition. In the previous example, +s+ would take you # inside the method definition of +get_foo+. # +r+:: # Restart the program. # +q+:: # Quit the program. # # === Inspecting variables # # You can use the debugger to easily inspect both local and global variables. # We've seen how to inspect local variables before: # # (rdb:1) p my_arg # 42 # # You can also pretty print the result of variables or expressions: # # (rdb:1) pp %w{a very long long array containing many words} # ["a", # "very", # "long", # ... # ] # # You can list all local variables with +v l+: # # (rdb:1) v l # foo => "hello" # # Similarly, you can show all global variables with +v g+: # # (rdb:1) v g # all global variables # # Finally, you can omit +p+ if you simply want to evaluate a variable or # expression # # (rdb:1) 5**2 # 25 # # === Going beyond basics # # Ruby Debug provides more advanced functionalities like switching # between threads, setting breakpoints and watch expressions, and more. # The full list of commands is available at any time by pressing +h+. # # == Staying out of trouble # # Make sure you remove every instance of +require 'debug'+ before # shipping your code.

It is much more # advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented # solution. # # === Features # # 1. The argument specification and the code to handle it are written in the # same place. # 2. It can output an option summary; you don't need to maintain this string # separately. # 3. Optional and mandatory arguments are specified very gracefully. # 4. Arguments can be automatically converted to a specified class. # 5. Arguments can be restricted to a certain set. # # All of these features are demonstrated in the examples below. See # #make_switch for full documentation. # # === Minimal example # # require 'optparse' # # options = {} # OptionParser.new do |parser| # parser.banner = "Usage: example.rb [options]" # # parser.on("-v", "--[no-]verbose", "Run verbosely") do |v| # options[:verbose] = v # end # end.parse! # # p options # p ARGV # # === Generating Help # # OptionParser can be used to automatically generate help for the commands you # write: # # require 'optparse' # # Options = Struct.new(:name) # # class Parser # def self.parse(options) # args = Options.new("world") # # opt_parser = OptionParser.new do |parser| # parser.banner = "Usage: example.rb [options]" # # parser.on("-nNAME", "--name=NAME", "Name to say hello to") do |n| # args.name = n # end # # parser.on("-h", "--help", "Prints this help") do # puts parser # exit # end # end # # opt_parser.parse!(options) # return args # end # end # options = Parser.parse %w[--help] # # #=> # # Usage: example.rb [options] # # -n, --name=NAME Name to say hello to # # -h, --help Prints this help # # === Required Arguments # # For options that require an argument, option specification strings may include an # option name in all caps. If an option is used without the required argument, # an exception will be raised. # # require 'optparse' # # options = {} # OptionParser.new do |parser| # parser.on("-r", "--require LIBRARY", # "Require the LIBRARY before executing your script") do |lib| # puts "You required #{lib}!" # end # end.parse! # # Used: # # $ ruby optparse-test.rb -r # optparse-test.rb:9:in `<main>': missing argument: -r (OptionParser::MissingArgument) # $ ruby optparse-test.rb -r my-library # You required my-library! # # === Type Coercion # # OptionParser supports the ability to coerce command line arguments # into objects for us. # # OptionParser comes with a few ready-to-use kinds of type # coercion. They are: # # - Date -- Anything accepted by +Date.parse+ # - DateTime -- Anything accepted by +DateTime.parse+ # - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+ # - URI -- Anything accepted by +URI.parse+ # - Shellwords -- Anything accepted by +Shellwords.shellwords+ # - String -- Any non-empty string # - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040) # - Float -- Any float. (e.g. 10, 3.14, -100E+13) # - Numeric -- Any integer, float, or rational (1, 3.4, 1/3) # - DecimalInteger -- Like +Integer+, but no octal format. # - OctalInteger -- Like +Integer+, but no decimal format. # - DecimalNumeric -- Decimal integer or float. # - TrueClass -- Accepts '+, yes, true, -, no, false' and # defaults as +true+ # - FalseClass -- Same as +TrueClass+, but defaults to +false+ # - Array -- Strings separated by ',' (e.g. 1,2,3) # - Regexp -- Regular expressions. Also includes options. # # We can also add our own coercions, which we will cover below. # # ==== Using Built-in Conversions # # As an example, the built-in +Time+ conversion is used. The other built-in # conversions behave in the same way. # OptionParser will attempt to parse the argument # as a +Time+. If it succeeds, that time will be passed to the # handler block. Otherwise, an exception will be raised. # # require 'optparse' # require 'optparse/time' # OptionParser.new do |parser| # parser.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time| # p time # end # end.parse! # # Used: # # $ ruby optparse-test.rb -t nonsense # ... invalid argument: -t nonsense (OptionParser::InvalidArgument) # $ ruby optparse-test.rb -t 10-11-12 # 2010-11-12 00:00:00 -0500 # $ ruby optparse-test.rb -t 9:30 # 2014-08-13 09:30:00 -0400 # # ==== Creating Custom Conversions # # The +accept+ method on OptionParser may be used to create converters. # It specifies which conversion block to call whenever a class is specified. # The example below uses it to fetch a +User+ object before the +on+ handler receives it. # # require 'optparse' # # User = Struct.new(:id, :name) # # def find_user id # not_found = ->{ raise "No User Found for id #{id}" } # [ User.new(1, "Sam"), # User.new(2, "Gandalf") ].find(not_found) do |u| # u.id == id # end # end # # op = OptionParser.new # op.accept(User) do |user_id| # find_user user_id.to_i # end # # op.on("--user ID", User) do |user| # puts user # end # # op.parse! # # Used: # # $ ruby optparse-test.rb --user 1 # #<struct User id=1, name="Sam"> # $ ruby optparse-test.rb --user 2 # #<struct User id=2, name="Gandalf"> # $ ruby optparse-test.rb --user 3 # optparse-test.rb:15:in `block in find_user': No User Found for id 3 (RuntimeError) # # === Store options to a Hash # # The +into+ option of +order+, +parse+ and so on methods stores command line options into a Hash. # # require 'optparse' # # params = {} # OptionParser.new do |parser| # parser.on('-a') # parser.on('-b NUM', Integer) # parser.on('-v', '--verbose') # end.parse!(into: params) # # p params # # Used: # # $ ruby optparse-test.rb -a # {:a=>true} # $ ruby optparse-test.rb -a -v # {:a=>true, :verbose=>true} # $ ruby optparse-test.rb -a -b 100 # {:a=>true, :b=>100} # # === Complete example # # The following example is a complete Ruby program.

session support for cgi scripts # # Copyright (C) 2001 Yukihiro "Matz" Matsumoto # Copyright (C) 2000 Network Applied Communication Laboratory, Inc. # Copyright (C) 2000 Information-technology Promotion Agency, Japan # # Author: Yukihiro "Matz" Matsumoto # # Documentation: William Webber (william@williamwebber.com) require 'cgi' require 'tmpdir' class CGI # == Overview # # This file provides the CGI::Session class, which provides session # support for CGI scripts. A session is a sequence of HTTP requests # and responses linked together and associated with a single client. # Information associated with the session is stored # on the server between requests. A session id is passed between client # and server with every request and response, transparently # to the user. This adds state information to the otherwise stateless # HTTP request/response protocol. # # == Lifecycle # # A CGI::Session instance is created from a CGI object. By default, # this CGI::Session instance will start a new session if none currently # exists, or continue the current session for this client if one does # exist. The +new_session+ option can be used to either always or # never create a new session. See #new() for more details. # # #delete() deletes a session from session storage. It # does not however remove the session id from the client. If the client # makes another request with the same id, the effect will be to start # a new session with the old session's id. # # == Setting and retrieving session data. # # The Session class associates data with a session as key-value pairs. # This data can be set and retrieved by indexing the Session instance # using '[]', much the same as hashes (although other hash methods # are not supported). # # When session processing has been completed for a request, the # session should be closed using the close() method. This will # store the session's state to persistent storage. If you want # to store the session's state to persistent storage without # finishing session processing for this request, call the update() # method. # # == Storing session state # # The caller can specify what form of storage to use for the session's # data with the +database_manager+ option to CGI::Session::new. The # following storage classes are provided as part of the standard library: # # CGI::Session::FileStore:: stores data as plain text in a flat file. Only # works with String data. This is the default # storage type. # CGI::Session::MemoryStore:: stores data in an in-memory hash. The data # only persists for as long as the current Ruby # interpreter instance does. # CGI::Session::PStore:: stores data in Marshalled format. Provided by # cgi/session/pstore.rb. Supports data of any type, # and provides file-locking and transaction support. # # Custom storage types can also be created by defining a class with # the following methods: # # new(session, options) # restore # returns hash of session data. # update # close # delete # # Changing storage type mid-session does not work. Note in particular # that by default the FileStore and PStore session data files have the # same name. If your application switches from one to the other without # making sure that filenames will be different # and clients still have old sessions lying around in cookies, then # things will break nastily! # # == Maintaining the session id. # # Most session state is maintained on the server. However, a session # id must be passed backwards and forwards between client and server # to maintain a reference to this session state. # # The simplest way to do this is via cookies. The CGI::Session class # provides transparent support for session id communication via cookies # if the client has cookies enabled. # # If the client has cookies disabled, the session id must be included # as a parameter of all requests sent by the client to the server. The # CGI::Session class in conjunction with the CGI class will transparently # add the session id as a hidden input field to all forms generated # using the CGI#form() HTML generation method. No built-in support is # provided for other mechanisms, such as URL re-writing. The caller is # responsible for extracting the session id from the session_id # attribute and manually encoding it in URLs and adding it as a hidden # input to HTML forms created by other mechanisms. Also, session expiry # is not automatically handled. # # == Examples of use # # === Setting the user's name # # require 'cgi' # require 'cgi/session' # require 'cgi/session/pstore' # provides CGI::Session::PStore # # cgi = CGI.new("html4") # # session = CGI::Session.new(cgi, # 'database_manager' => CGI::Session::PStore, # use PStore # 'session_key' => '_rb_sess_id', # custom session key # 'session_expires' => Time.now + 30 * 60, # 30 minute timeout # 'prefix' => 'pstore_sid_') # PStore option # if cgi.has_key?('user_name') and cgi['user_name'] != '' # # coerce to String: cgi[] returns the # # string-like CGI::QueryExtension::Value # session['user_name'] = cgi['user_name'].to_s # elsif !session['user_name'] # session['user_name'] = "guest" # end # session.close # # === Creating a new session safely # # require 'cgi' # require 'cgi/session' # # cgi = CGI.new("html4") # # # We make sure to delete an old session if one exists, # # not just to free resources, but to prevent the session # # from being maliciously hijacked later on. # begin # session = CGI::Session.new(cgi, 'new_session' => false) # session.delete # rescue ArgumentError # if no old session # end # session = CGI::Session.new(cgi, 'new_session' => true) # session.close # class Session class NoSession < RuntimeError #:nodoc: end # The id of this session. attr_reader :session_id, :new_session def Session::callback(dbman) #:nodoc: Proc.new{ dbman[0].close unless dbman.empty? } end # Create a new session id. # # The session id is a secure random number by SecureRandom # if possible, otherwise an SHA512 hash based upon the time, # a random number, and a constant string.

If not provided, then # it is retrieved from the +session_key+ parameter # of the request, or automatically generated for # a new session. # new_session:: if true, force creation of a new session. If not set, # a new session is only created if none currently # exists. If false, a new session is never created, # and if none currently exists and the +session_id+ # option is not set, an ArgumentError is raised. # database_manager:: the name of the class providing storage facilities # for session state persistence. Built-in support # is provided for +FileStore+ (the default), # +MemoryStore+, and +PStore+ (from # cgi/session/pstore.rb).

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone'
