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 24

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

.null

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 39

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

.to_basic(list)

name, version, platform

tuples.

#==(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 101

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

#eql?(other)

Alias for #==.

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 114

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 48

def full_name
  case @platform
  when nil, "", Gem::Platform::RUBY
    "#{@name}-#{@version}"
  else
    "#{@name}-#{@version}-#{@platform}"
  end
end

#hash

# File 'lib/rubygems/name_tuple.rb', line 116

def hash
  to_a.hash
end

#inspect Also known as: #to_s

This method is for internal use only.
[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 84

def inspect # :nodoc:
  "#<Gem::NameTuple #{@name}, #{@version}, #{@platform}>"
end

#spec_name

Return the name that the gemspec file would be

[ GitHub ]

  
# File 'lib/rubygems/name_tuple.rb', line 73

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 80

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

#to_s

This method is for internal use only.

Alias for #inspect.
