Gem::Platform

Available list of platforms for targeting Gem installations.

See `gem help platform` for information on platform matching.

Constants

CURRENT

A platform-specific gem that is built for the packaging Ruby's platform. This will be replaced with Gem::Platform::local.

RUBY

A pure-Ruby gem that may use Gem::Specification#extensions to build binary files.

Attributes

cpu[RW]
os[RW]
version[RW]

==(other) click to toggle source

Is other equal to this platform? Two platforms are equal if they have the same CPU, OS and version.

 
               # File rubygems/platform.rb, line 130
def ==(other)
  self.class === other and to_a == other.to_a
end
Also aliased as: eql?
===(other) click to toggle source

Does other match this platform? Two platforms match if they have the same CPU, or either has a CPU of 'universal', they have the same OS, and they have the same version, or either has no version.

Additionally, the platform will match if the local CPU is 'arm' and the other CPU starts with “arm” (for generic ARM family support).

 
               # File rubygems/platform.rb, line 148
def ===(other)
  return nil unless Gem::Platform === other

  # cpu
  ([nil,'universal'].include?(@cpu) or [nil, 'universal'].include?(other.cpu) or @cpu == other.cpu or
  (@cpu == 'arm' and other.cpu =~ /\Aarm/)) and

  # os
  @os == other.os and

  # version
  (@version.nil? or other.version.nil? or @version == other.version)
end
=~(other) click to toggle source

Does other match this platform? If other is a String it will be converted to a Gem::Platform first. See === for matching rules.
