The Specification
class contains the information for a Gem. Typically defined in a .gemspec file or a Rakefile, and looks like this:
Gem::Specification.new do |s| s.name = 'example' s.version = '0.1.0' s.licenses = ['MIT'] s.summary = "This is an example!" s.description = "Much longer explanation of the example!" s.authors = ["Ruby Coder"] s.email = 'rubycoder@example.com' s.files = ["lib/example.rb"] s.homepage = 'https://rubygems.org/gems/example' s.metadata = { "source_code_uri" => "https://github.com/example/example" } end
Starting in RubyGems 2.0, a Specification
can hold arbitrary metadata. See metadata
for restrictions on the format and size of metadata items you may add to a specification.
The version number of a specification that does not specify one (i.e. RubyGems 0.7 or earlier).
A message that gets displayed after the gem is installed.
Usage:
spec.post_install_message = "Thanks for installing!"
Adds a development dependency named gem
with requirements
to this gem.
Usage:
spec.add_development_dependency 'example', '~> 1.1', '>= 1.1.4'
Development dependencies aren't installed by default and aren't activated when a gem is required.
# File rubygems/specification.rb, line 538 def add_development_dependency(gem, *requirements) add_dependency_with_type(gem, :development, requirements) end
Adds a runtime dependency named gem
with requirements
to this gem.
Usage:
spec.add_runtime_dependency 'example', '~> 1.1', '>= 1.1.4'
# File rubygems/specification.rb, line 549 def add_runtime_dependency(gem, *requirements) add_dependency_with_type(gem, :runtime, requirements) end
Executables included in the gem.
For example, the rake gem has rake as an executable. You don’t specify the full path (as in bin/rake); all application-style files are expected to be found in bindir. These files must be executable Ruby files. Files that use bash or other interpreters will not work.
Executables included may only be ruby scripts, not scripts for other languages or compiled binaries.
Usage:
spec.executables << 'rake'
# File rubygems/specification.rb, line 568 def executables @executables ||= [] end
Extensions to build when installing the gem, specifically the paths to extconf.rb-style files used to compile extensions.
These files will be run when the gem is installed, causing the C (or whatever) code to be compiled on the user’s machine.
Usage:
spec.extensions << 'ext/rmagic/extconf.rb'
See Gem::Ext::Builder
for information about writing extensions for gems.
# File rubygems/specification.rb, line 585 def extensions @extensions ||= [] end
Extra files to add to RDoc such as README or doc/examples.txt
When the user elects to generate the RDoc documentation for a gem (typically at install time), all the library files are sent to RDoc for processing. This option allows you to have some non-code files included for a more complete set of documentation.
Usage:
spec.extra_rdoc_files = ['README', 'doc/user-guide.txt']
# File rubygems/specification.rb, line 601 def extra_rdoc_files @extra_rdoc_files ||= [] end
The platform this gem runs on.
This is usually Gem::Platform::RUBY or Gem::Platform::CURRENT.
Most gems contain pure Ruby code; they should simply leave the default value in place. Some gems contain C (or other) code to be compiled into a Ruby “extension”. The gem should leave the default value in place unless the code will only compile on a certain type of system. Some gems consist of pre-compiled code (“binary gems”). It's especially important that they set the platform attribute appropriately. A shortcut is to set the platform to Gem::Platform::CURRENT, which will cause the gem builder to set the platform to the appropriate value for the system on which the build is being performed.
If this attribute is set to a non-default value, it will be included in the filename of the gem when it is built such as: nokogiri-1.6.0-x86-mingw32.gem
Usage:
spec.platform = Gem::Platform.local
# File rubygems/specification.rb, line 450 def platform= platform if @original_platform.nil? or @original_platform == Gem::Platform::RUBY then @original_platform = platform end case platform when Gem::Platform::CURRENT then @new_platform = Gem::Platform.local @original_platform = @new_platform.to_s when Gem::Platform then @new_platform = platform # legacy constants when nil, Gem::Platform::RUBY then @new_platform = Gem::Platform::RUBY when 'mswin32' then # was Gem::Platform::WIN32 @new_platform = Gem::Platform.new 'x86-mswin32' when 'i586-linux' then # was Gem::Platform::LINUX_586 @new_platform = Gem::Platform.new 'x86-linux' when 'powerpc-darwin' then # was Gem::Platform::DARWIN @new_platform = Gem::Platform.new 'ppc-darwin' else @new_platform = Gem::Platform.new platform end @platform = @new_platform.to_s invalidate_memoized_attributes @new_platform end
Specifies the rdoc options to be used when generating API documentation.
Usage:
spec.rdoc_options << '--title' << 'Rake -- Ruby Make' << '--main' << 'README' << '--line-numbers'
# File rubygems/specification.rb, line 631 def rdoc_options @rdoc_options ||= [] end
Paths in the gem to add to $LOAD_PATH
when this gem is activated. If you have an extension you do not need to add "ext"
to the require path, the extension build process will copy the extension files into “lib” for you.
The default value is "lib"
Usage:
# If all library files are in the root directory... spec.require_paths = ['.']
# File rubygems/specification.rb, line 501 def require_paths=(val) @require_paths = Array(val) end
The version of Ruby required by this gem. The ruby version can be specified to the patch-level:
$ ruby -v -e 'p Gem.ruby_version' ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0] #<Gem::Version "2.0.0.247">
Because patch-level is taken into account, be very careful specifying using `<=`: `<= 2.2.2` will not match any patch-level of 2.2.2 after the `p0` release. It is much safer to specify `< 2.2.3` instead
Usage:
# This gem will work with 1.8.6 or greater... spec.required_ruby_version = '>= 1.8.6' # Only with ruby 2.0.x spec.required_ruby_version = '~> 2.0' # Only with ruby between 2.2.0 and 2.2.2 spec.required_ruby_version = ['>= 2.2.0', '< 2.2.3']
# File rubygems/specification.rb, line 658 def required_ruby_version= req @required_ruby_version = Gem::Requirement.create req end
The RubyGems version required by this gem
# File rubygems/specification.rb, line 665 def required_rubygems_version= req @required_rubygems_version = Gem::Requirement.create req end
Lists the external (to RubyGems) requirements that must be met for this gem to work. It's simply information for the user.
Usage:
spec.requirements << 'libmagick, v6.0' spec.requirements << 'A good graphics card'
# File rubygems/specification.rb, line 678 def requirements @requirements ||= [] end
A long description of this gem
The description should be more detailed than the summary but not excessively long. A few paragraphs is a recommended length with no examples or formatting.
Usage:
spec.description = <<-EOF Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. EOF
A contact email address (or addresses) for this gem
Usage:
spec.email = 'john.jones@example.com' spec.email = ['jack@example.com', 'jill@example.com']
The metadata holds extra data for this gem that may be useful to other consumers and is settable by gem authors without requiring an update to the rubygems software.
Metadata items have the following restrictions:
The metadata must be a Hash object
All keys and values must be Strings
Keys can be a maximum of 128 bytes and values can be a maximum of 1024 bytes
All strings must be UTF-8, no binary data is allowed
You can use metadata to specify links to your gem's homepage, codebase, documentation, wiki, mailing list, issue tracker and changelog.
s.metadata = { "bug_tracker_uri" => "https://example.com/user/bestgemever/issues", "changelog_uri" => "https://example.com/user/bestgemever/CHANGELOG.md", "documentation_uri" => "https://www.example.info/gems/bestgemever/0.0.1", "homepage_uri" => "https://bestgemever.example.io", "mailing_list_uri" => "https://groups.example.com/bestgemever", "source_code_uri" => "https://example.com/user/bestgemever", "wiki_uri" => "https://example.com/user/bestgemever/wiki" }
These links will be used on your gem's page on rubygems.org and must pass validation against following regex.
%r{\Ahttps?:\/\/([^\s:@]+:[^\s:@]*@)?[A-Za-z\d\-]+(\.[A-Za-z\d\-]+)+\.?(:\d{1,5})?([\/?]\S*)?\z}
The license for this gem.
The license must be no more than 64 characters.
This should just be the name of your license. The full text of the license should be inside of the gem (at the top level) when you build it.
The simplest way, is to specify the standard SPDX ID spdx.org/licenses/ for the license. Ideally you should pick one that is OSI (Open Source Initiative) opensource.org/licenses/alphabetical approved.
The most commonly used OSI approved licenses are MIT and Apache-2.0. GitHub also provides a license picker at choosealicense.com/.
You should specify a license for your gem so that people know how they are permitted to use it, and any restrictions you're placing on it. Not specifying a license means all rights are reserved; others have no rights to use the code for any purpose.
You can set multiple licenses with licenses=
Usage:
spec.license = 'MIT'
# File rubygems/specification.rb, line 346 def license=o self.licenses = [o] end
The license(s) for the library.
Each license must be a short name, no more than 64 characters.
This should just be the name of your license. The full text of the license should be inside of the gem when you build it.
See license=
for more discussion
Usage:
spec.licenses = ['MIT', 'GPL-2.0']
# File rubygems/specification.rb, line 363 def licenses= licenses @licenses = Array licenses end
A short summary of this gem's description. Displayed in `gem list -d`.
The description
should be more detailed than the summary.
Usage:
spec.summary = "This is a small summary of my gem"
Files included in this gem. You cannot append to this accessor, you must assign to it.
Only add files you can require to this list, not directories, etc.
Directories are automatically stripped from this list when building a gem, other non-files cause an error.
Usage:
require 'rake' spec.files = FileList['lib/**/*.rb', 'bin/*', '[A-Z]*', 'test/**/*'].to_a # or without Rake... spec.files = Dir['lib/**/*.rb'] + Dir['bin/*'] spec.files += Dir['[A-Z]*'] + Dir['test/**/*'] spec.files.reject! { |fn| fn.include? "CVS" }
# File rubygems/specification.rb, line 249 def files # DO NOT CHANGE TO ||= ! This is not a normal accessor. (yes, it sucks) # DOC: Why isn't it normal? Why does it suck? How can we fix this? @files = [@files, @test_files, add_bindir(@executables), @extra_rdoc_files, @extensions, ].flatten.compact.uniq.sort end
Sets the default executable for this gem.
Deprecated: You must now specify the executable name to Gem.bin_path
.
The rubyforge project this gem lives under. i.e. RubyGems' rubyforge_project
is “rubygems”.
This option is deprecated.
The Gem::Specification
version of this gemspec.
Do not set this, it is set automatically when the gem is packaged.

Special loader for YAML files. When a Specification
object is loaded from a YAML file, it bypasses the normal Ruby object initialization routine (initialize). This method makes up for that and deals with gems of different ages.

Abbreviate the spec for downloading. Abbreviated specs are only used for searching, downloading and related activities and do not need deployment specific information (e.g. list of files). So we abbreviate the spec, making it much smaller for quicker downloads.
