The next time you visit your repository’s edit screen you’ll see a new checkbox that should be pretty exciting for users hosting their RubyGem project on GitHub:

After checking that, managing your gem is as simple as managing a gemspec in your project’s root directory (example). Anytime you push a modified gemspec to GitHub, we’ll build and publish a new gem for you.
Feel free to give your open source friends a hard time when they don’t release a new gem version for a while, because they have no excuse now 🙂
One concept regarding our server that bears repeating is that your gem will always be prefixed with your username. Installing mojombo’s grit gem is done via the following:
$ sudo gem install mojombo-grit Successfully installed mojombo-grit-0.8.1
Using said gem works a couple of ways. First the regular require:
$ irb -rubygems >> require 'grit' => true
Update: The following also works if you have competing versions of the same gem:
$ irb -rubygems >> gem 'mojombo-grit' => true >> require 'grit' => true
The namespacing may feel awkward as first, but it really lends itself to the distributed nature of the service we provide. Forking a RubyGem project shouldn’t be any more complicated than forking any other type of project.
Visit http://gems.github.com for all of the details. Enjoy!
