Browse the gems in your Gemfile and open their source in a new Sublime window, all without leaving the editor. Note: this plugin is for users of rvm gemsets. For other project structures, check out SublimeGemBrowser, on which this plugin is based.
Copy to your sublime packages directory. (In OS X: ~/Library/Application Support/Sublime Text 2/Packages)
Then add a keyboard binding:
{ "keys": ["super+ctrl+e"], "command": "sublime_gem_browser_gemset" }
Then hit ⌘-CTRL-e to fuzzy search your gems.
