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:
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.summary = "Ruby based make-like utility." s.name = 'rake' s.version = PKG_VERSION s.requirements << 'none' 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
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.
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.
# File rubygems/package_task.rb, line 77 def initialize(gem_spec) init gem_spec yield self if block_given? define if block_given? end
Create the Rake tasks and actions specified by this Gem::PackageTask. (define
is
automatically called if a block is given to new
).
# File rubygems/package_task.rb, line 96 def define super gem_file = File.basename gem_spec.cache_file gem_path = File.join package_dir, gem_file gem_dir = File.join package_dir, gem_spec.full_name task :package => [:gem] directory package_dir directory gem_dir desc "Build the gem file #{gem_file}" task :gem => [gem_path] trace = Rake.application.options.trace Gem.configuration.verbose = trace file gem_path => [package_dir, gem_dir] + @gem_spec.files do chdir(gem_dir) do when_writing "Creating #{gem_spec.file_name}" do Gem::Package.build gem_spec verbose trace do mv gem_file, '..' end end end end end
