Sharing Source Code From a Public git Repository

The simplest way (from the author’s perspective) to share a gem for other developers’ use is to distribute it in source code form. If you place the full source code for your gem on a public git repository, then other users can install it with Bundler's git functionality.

For example, you can install the latest code for the wicked_pdf gem in a project by including this line in your Gemfile:

gem "wicked_pdf", :git => "git://github.com/mileszs/wicked_pdf.git"

(Véase bundle help gemfile)

Installing a gem directly from a git repository is a feature of Bundler, not a feature of RubyGems. Gems installed this way will not show up when you run gem list.
