Class Gem::PackageTask
In: lib/rubygems/package_task.rb
Parent: Rake::PackageTask

Create a package based upon a Gem::Specification. Gem packages, as well as zip files and tar/gzipped packages can be produced by this task.

In addition to the Rake targets generated by Rake::PackageTask, a Gem::PackageTask will also generate the following tasks:

"package_dir/name-version.gem"
Create a RubyGems package with the given name and version.

Example using a Gem::Specification: 

  require 'rubygems'
  require 'rubygems/package_task'

  spec = Gem::Specification.new do |s|
    s.platform = Gem::Platform::RUBY
    s.summary = "Ruby based make-like utility."
    s.name = 'rake'
    s.version = PKG_VERSION
    s.requirements << 'none'
    s.require_path = 'lib'
    s.autorequire = 'rake'
    s.files = PKG_FILES
    s.description = <<-EOF
  Rake is a Make-like program implemented in Ruby. Tasks
  and dependencies are specified in standard Ruby syntax.
    EOF
  end

  Gem::PackageTask.new(spec) do |pkg|
    pkg.need_zip = true
    pkg.need_tar = true
  end

Attributes

gem_spec  [RW]  Ruby Gem::Specification containing the metadata for this package. The name, version and package_files are automatically determined from the gemspec and don‘t need to be explicitly provided.

Public Class methods

new(gem_spec) {|self if block_given?| ...}

Create a Gem Package task library. Automatically define the gem if a block is given. If no block is supplied, then define needs to be called to define the task.

Public Instance methods

define()

Create the Rake tasks and actions specified by this Gem::PackageTask. (define is automatically called if a block is given to new).
