OpenGem

Simply opens the specified gem in your default editor.

gem open rails

If you just want to read documentation you can do:

gem read activerecord

Installation:

OpenGem require rubygems 1.3.2 or higher. You may need to update rubygems to take advantage of the new plugin support:

gem update --system

Just install like any normal gem:

gem install open_gem

Or for the edge version use GemCutter.org:

gem sources -a http://gemcutter.org
gem install open_gem

For more help:

gem open --help
