Class: Gem::Specification

Inherits:
BasicSpecification show all
Extended by:
Enumerable, Deprecate
Defined in:
lib/rubygems/specification.rb

Overview

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       = '[email protected]'
  s.files       = ["lib/example.rb"]
  s.homepage    = 'https://rubygems.org/gems/example'
  s.    = { "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.

Constant Summary collapse

NONEXISTENT_SPECIFICATION_VERSION =

The version number of a specification that does not specify one (i.e. RubyGems 0.7 or earlier).

-1
CURRENT_SPECIFICATION_VERSION =

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

– When updating this number, be sure to also update #to_ruby.

NOTE RubyGems < 1.2 cannot load specification versions > 2.

SPECIFICATION_VERSION_HISTORY =

  • 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. = {
  "bug_tracker_uri"   => "https://example.com/user/bestgemever/issues",
  "changelog_uri"     => "https://example.com/user/bestgemever/CHANGELOG.md",

  "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}

end

#executablesObject

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'


576
577
578
# File 'lib/rubygems/specification.rb', line 576

def executables
  @executables ||= []

#extensionsObject

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.



593
594

# File 'lib/rubygems/specification.rb', line 593

#extra_rdoc_filesObject

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']

611
# File 'lib/rubygems/specification.rb', line 609

1934
1935
1936
# File 'lib/rubygems/specification.rb', line 1934

def file_name
  "#{full_name}.gem"
end

#filesObject

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" }

#license=(o) ⇒ Object

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 'lib/rubygems/specification.rb', line 344

def license=(o)

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']

2240
2241
# File 'lib/rubygems/specification.rb', line 2239

def platform
  @new_platform ||= Gem::Platform::RUBY
end

#platform=(platform) ⇒ Object

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
