I love Textmate's simple when I'm working on Ruby or any RoR project. But sometime it is just too simple to a big Rails project. Some feature like auto_complete, simple refatoring, basic code navigation would give a lot productivity when you have a big codebase. I would like to give it a shot to bring those feature to Textmate through a bundel.
install
mkdir -p /Library/Application\ Support/TextMate/Bundles cd !$ svn checkout http://evil-rails.googlecode.com/svn/trunk EvilRails.tmbundle osascript -e 'tell app "TextMate" to reload bundles'
