Overview

Ruby Gem Package Installer

The gem package installer installs ruby gems.

The installer has a single optional configuration: source. By changing source you can specify a given ruby gems repository from which to install.

Example Usage

First, a simple installation of the magic_beans gem:

package :magic_beans do
  description "Beans beans they're good for your heart..."
  gem 'magic_beans'
end

Second, install magic_beans gem from github:

package :magic_beans do
  gem 'magic_beans_package' do
    source 'http://gems.github.com'
  end
end

As you can see, setting options is as simple as creating a block and calling the option as a method with the value as its parameter.

def source(location = nil) #:nodoc:
  # package defines an installer called source so here we specify a method directly
  # rather than rely on the automatic options processing since packages' method missing
  # won't be run
  return @options[:source] unless location
  @options[:source] = location
end
