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       = 'rubycoder@example.com'
  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.

Constructor Details

.new(name = nil, version = nil) {|_self| ... } ⇒ Specification

Specification constructor. Assigns the default values to the attributes and yields itself for further initialization. Optionally takes #name and #version.

Yields:

  • (_self)

Yield Parameters:

  • _self (Specification)

    the object that the method was called on

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(sym, *a, &b)

This method is for internal use only.

Track removed method calls to warn about during build time. Warn about unknown attributes while loading a spec.

[ GitHub ]

  
# File 'lib/rubygems/specification.rb', line 2184

def method_missing(sym, *a, &b) # :nodoc:
  if REMOVED_METHODS.include?(sym)
    removed_method_calls << sym
    return
  end

  if @specification_version > CURRENT_SPECIFICATION_VERSION &&
     sym.to_s.end_with?("=")
    warn "ignoring #{sym} loading #{full_name}" if $DEBUG
  else
    super

Class Attribute Details

.all (rw)

Returns all specifications. This method is discouraged from use. You probably want to use one of the Enumerable methods instead.

def self.all
  warn "NOTE: Specification.all called from #{caller.first}" unless

.all=(specs) (rw)

Sets the known specs to specs. Not guaranteed to work for you in the future. Use at your own risk. Caveat emptor. Doomy doom doom. Etc etc.

def self.all=(specs)
  @@stubs_by_name = specs.group_by(&:name)

def self.dirs
  @@dirs ||= Gem.path.collect do |dir|
    File.join dir, "specifications"

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.

Singular accessor for #licenses

# File 'lib/rubygems/specification.rb', line 2149

def license

end

#license=(o) (rw)

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'
[ GitHub ]

  
# File 'lib/rubygems/specification.rb', line 360

def license=(o)
  self.licenses = [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']

def licenses=(licenses)

#metadata (rw)

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

  "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.

# File 'lib/rubygems/specification.rb', line 2259

def platform
  @new_platform ||= Gem::Platform::RUBY # rubocop:disable Naming/MemoizedInstanceVariableName
end

#platform=(platform) (rw)

The platform this gem runs on.

This is usually Platform::RUBY or 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 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
