# Rake::PackageTask

Create a packaging task that will package the project into distributable files (e.g zip archive or tar files).

The PackageTask will create the following targets:

`:package`

  Create all the requested package files.

`:clobber_package`

  Delete all the package files. This target is automatically added to the main clobber target.

`:repackage`

  Rebuild the package files from scratch, even if they are not out of date.

`"package_dir/name-version.tgz"`

  Create a gzipped tar package (if need_tar is true).

`"package_dir/name-version.tar.gz"`

  Create a gzipped tar package (if need_tar_gz is true).

`"package_dir/name-version.tar.bz2"`

  Create a bzip2'd tar package (if need_tar_bz2 is true).

`"package_dir/name-version.zip"`

  Create a zip package archive (if need_zip is true).

Example:

    Rake::PackageTask.new("rake", "1.2.3") do |p|
      p.need_tar = true
      p.package_files.include("lib   /*.rb")
    end

### Attributes

name[RW]

Name of the package (from the GEM Spec).

need_tar[RW]

True if a gzipped tar file (tgz) should be produced (default is false).

need_tar_bz2[RW]

True if a bzip2'd tar file (tar.bz2) should be produced (default is false).

need_tar_gz[RW]

True if a gzipped tar file (tar.gz) should be produced (default is false).

need_zip[RW]

True if a zip file should be produced (default is false)

package_dir[RW]

Directory used to store the package files (default is 'pkg').

package_files[RW]

List of files to be included in the package.

tar_command[RW]

Tar command for gzipped or bzip2ed archives. The default is 'tar'.

version[RW]

Version of the package (e.g. '1.3.2').

zip_command[RW]

Zip command for zipped archives. The default is 'zip'.

### Public Class Methods

new(name=nil, version=nil) click to toggle source

Create a Package Task with the given name and version. Use `:noversion` as the version to build a package without a version or to provide a fully-versioned package name.

                   # File rake/packagetask.rb, line 82
    def initialize(name=nil, version=nil)
      init(name, version)
      yield self if block_given?
      define unless name.nil?
    end

### Public Instance Methods

define() click to toggle source

Create the tasks defined by this task library.

                   # File rake/packagetask.rb, line 103
    def define
      fail "Version required (or :noversion)" if @version.nil?
      @version = nil if :noversion == @version

      desc "Build all the packages"
      task :package

      desc "Force a rebuild of the package files"
      task :repackage => [:clobber_package, :package]

      desc "Remove package products"
      task :clobber_package do
        rm_r package_dir rescue nil
      end

      task :clobber => [:clobber_package]

      [
        [need_tar, tgz_file, "z"],
        [need_tar_gz, tar_gz_file, "z"],
        [need_tar_bz2, tar_bz2_file, "j"]
      ].each do |(need, file, flag)|
        if need
          task :package => ["#{package_dir}/#{file}"]
          file "#{package_dir}/#{file}" =>
            [package_dir_path] + package_files do
            chdir(package_dir) do
              sh @tar_command, "#{flag}cvf", file, package_name
            end
          end
        end
      end

      if need_zip
        task :package => ["#{package_dir}/#{zip_file}"]
        file "#{package_dir}/#{zip_file}" =>
          [package_dir_path] + package_files do
          chdir(package_dir) do
            sh @zip_command, "-r", zip_file, package_name
          end
        end
      end

      directory package_dir_path => @package_files do
        @package_files.each do |fn|

          fdir = File.dirname(f)
          mkdir_p(fdir) unless File.exist?(fdir)
          if File.directory?(fn)
            mkdir_p(f)
          else
            rm_f f

    def init(name, version)
      @name = name
      @version = version
      @package_files = Rake::FileList.new
      @package_dir = 'pkg'

      @need_tar_gz = false
      @need_tar_bz2 = false

      @tar_command = 'tar'
      @zip_command = 'zip'
    end

package_dir_path() click to toggle source

    end

package_name() click to toggle source

The name of this package

                   # File rake/packagetask.rb, line 164

    end

tar_bz2_file() click to toggle source
