Gem Version Build Status


Powerpack offers some useful extensions to the standard Ruby classes (kind of like ActiveSupport, but less ambitious and more modular).


Add this line to your application's Gemfile (if you're using bundler, that is):

gem 'powerpack'

And then execute:

$ bundle

Or install it yourself as:

$ gem install powerpack



A listing of the extensions provided by Powerpack is available here.


To load the entire powerpack do:

require 'powerpack'

To load only the String extensions do:

require 'powerpack/string'

To load only a specific extension like String#format do:

require 'powerpack/string/format'


Powerpack's changelog is available here.
