end

Class Method Details

.from_list(list)

Turn an array of [name, version, platform] into an array of NameTuple objects.

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 26

def self.from_list list
  list.map { |t| new(*t) }
end

.null

A null NameTuple, ie name=nil, version=0

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 41

def self.null
  new nil, Gem::Version.new(0), nil
end

.to_basic(list)

Turn an array of NameTuple objects back into an array of

name, version, platform

tuples.

# File 'lib/rubygems/name_tuple.rb', line 34

def self.to_basic list
  list.map { |t| t.to_a }

attr_reader :name, :version, :platform

#prerelease?Boolean (readonly)

Indicate if this NameTuple is for a prerelease version.

#<=>(other)

[ GitHub ]

def <=> other
  [@name, @version, @platform == Gem::Platform::RUBY ? -1 : 1] <=>
    [other.name, other.version,
     other.platform == Gem::Platform::RUBY ? -1 : 1]
end

#==(other) Also known as: #eql?

Compare with other. Supports another NameTuple or an Array in the [name, version, platform] format.

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 104

def == other
  case other
  when self.class
    @name == other.name and
      @version == other.version and
      @platform == other.platform
  when Array
    to_a == other
  else
    false
  end
end

#eql?(other)

Alias for #==.

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 117

alias_method :eql?, :==

#full_name

Returns the full name (name-version) of this ::Gem. Platform information is included if it is not the default Ruby platform. This mimics the behavior of Specification#full_name.

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 50

def full_name
  case @platform
  when nil, 'ruby', ''
    "#{@name}-#{@version}"
  else
    "#{@name}-#{@version}-#{@platform}"
  end.untaint
end

#hash

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 119

def hash
  to_a.hash
end

#spec_name

Return the name that the gemspec file would be

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 75

def spec_name
  "#{full_name}.gemspec"
end

#to_a

Convert back to the [name, version, platform] tuple

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 82

def to_a
  [@name, @version, @platform]
end
