Ruby wrapper that supports all of the GitHub API v3 methods(nearly 200). It's build in a modular way, that is, you can either instantiate the whole api wrapper Github.new or use parts of it e.i. Github::Repos.new if working solely with repositories is your main concern.
Gemfile gem 'github_api', '~> 0.4.7'
