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).
The specification version applied to any new Specification instances created. This should be bumped whenever something in the spec format changes.
Specification Version History:
spec ruby
ver ver yyyy-mm-dd description
-1 <0.8.0 pre-spec-version-history
1 0.8.0 2004-08-01 Deprecated "test_suite_file" for "test_files"
"test_file=x" is a shortcut for "test_files=[x]"
2 0.9.5 2007-10-01 Added "required_rubygems_version"
Now forward-compatible with future versions
3 1.3.2 2009-01-03 Added Fixnum validation to specification_version
4 1.9.0 2011-06-07 Added metadata
An informal list of changes to the specification. The highest-valued key should be equal to the CURRENT_SPECIFICATION_VERSION.

This gem’s name.
Usage:
spec.name = 'rake'
This gem’s version.
The version string can contain numbers and periods, such as 1.0.0. A gem is a ‘prerelease’ gem if the version has a letter in it, such as 1.0.0.pre.
Usage:
spec.version = '0.4.1'
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"
The version of Ruby required by this gem
Usage:
spec.required_ruby_version = '>= 2.7.0'
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 URL of this gem’s home page
Usage:
spec.homepage = 'https://github.com/ruby/rake'
The metadata holds extra data for this gem that may be useful to other consumers and is settable by gem authors.
Metadata items have the following restrictions:
-
The metadata must be a
Hashobject -
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"
"funding_uri" => "https://example.com/donate"
}
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 path in the gem for executable scripts. Usually ‘exe’
Usage:
spec.bindir = 'exe'
The certificate chain used to sign this gem. See Gem::Security for details.
A message that gets displayed after the gem is installed.
Usage:
spec.post_install_message = "Thanks for installing!"
The RubyGems version required by this gem
The key used to sign this gem. See Gem::Security for details.
The version of RubyGems used to create this gem.
True when this gemspec has been activated. This attribute is not persisted.

Singular accessor for executables
# File tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 574
def executables
@executables ||= []
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 tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 1854
def executables=(value)
@executables = Array(value)
end
Sets executables to value, ensuring it is an array.

def extensions
@extensions ||= []
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 tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 1861

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 tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 1868

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]*'].to_a # or without Rake... spec.files = Dir['lib/**/*.rb'] + Dir['bin/*'] spec.files += Dir['[A-Z]*'] spec.files.reject! { |fn| fn.include? "CVS" }

Singular accessor for licenses
# File tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 351
def license=(o)
self.licenses = [o]
end
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/ approved.
The most commonly used OSI-approved licenses are MIT and Apache-2.0. GitHub also provides a license picker at choosealicense.com/.
You can also use a custom license file along with your gemspec and specify a LicenseRef-<idstring>, where idstring is the name of the file containing the license text.
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 right to use the code for any purpose.
You can set multiple licenses with licenses=
Usage:
spec.license = 'MIT'
# File tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 2093
def licenses
@licenses ||= []
end
Plural accessor for setting licenses
See license= for details
# File tmp/rubies/ruby-master/lib/rubygems/specification.rb, line 368
def licenses=(licenses)
@licenses = Array licenses
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']

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

spec.platform = Gem::Platform.local
