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

Public Instance Methods
Is other
equal to this platform? Two platforms are equal if
they have the same CPU, OS and version.
# File lib/rubygems/platform.rb, line 128 def ==(other) self.class === other and to_a == other.to_a end
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 lib/rubygems/platform.rb, line 146 def ===(other) return nil unless Gem::Platform === other # cpu (@cpu == 'universal' or other.cpu == 'universal' 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
Does other
match this platform? If other
is a
String it will be converted to a Gem::Platform
first. See === for matching
rules.
