vim ctags goto definition and omni-complete August 16th, 2008
When you're reviewing or writing lots of code, it helps to have a sharp tool. I prefer to write ruby and just about everything else in vim since it's available on all platforms and I'm constantly switching from platform to platform (mostly Linux and OSX these days though).
Vim is a great, lightweight, powerful editor with all the features that any other editor can provide (yeah, even the famed textmate has nothing vim doesn't have). The steps below can get you going at a birds eye view.
1) compile vim with ruby support (if you don't already have it). To see if ruby support is enabled type 'vim --version' and look for "+ruby". If you see "-ruby" then ruby support is not enabled.
2) install ctags (via apt-get or ports). You can run it in your project's directory and jump-to-definition will start working:
ctags -R --exclude=*.js4) cook up a great .vimrc
