First came Vim, and next Gaizka added APIdock integration to Emacs. Now perhaps the biggest favorite of most Ruby and Rails developers, myself included: Textmate! Courtesy of one of Nodeta’s own, Ville Lautanala aka Lautis, you can get the Textmate bundles with APIdock goodness for Ruby and Rails from github with just a couple of simple git commands:

% mkdir -p ~/Library/Application\ Support/Textmate/Bundles
% cd ~/Library/Application\ Support/Textmate/Bundles
% git clone git:// "Ruby on Rails.tmbundle"
% git clone git:// "Ruby.tmbundle"
% osascript -e 'tell app "TextMate" to reload bundles'

Now, the keyboard shortcut


gets you the page for the current word from APIdock.
