Snow Leo ships with ctags not suitable for Ruby development. Ie if you try to generate tags recursively, it will error out:

$ ctags R
ctags: illegal option - R
usage: ctags [-BFadtuwvx] [-f tagsfile] file …

$ which ctags
/usr/bin/ctags
homebrew to the rescue:

$ brew install ctags
==> Downloading http://downloads.sourceforge.net/ctags/ctags-5.8.tar.gz

1. 100.0%
   ==> ./configure —prefix=/usr/local/Cellar/ctags/5.8 —enable-macro-patterns —mandir=/usr/local/Cellar/ctags/5.8/share/man —with-readlib
   ==> make install
   /usr/local/Cellar/ctags/5.8: 6 files, 392K, built in 12 seconds
   Now we need to alias ctags to use new version:

$ alias ctags=“`brew —prefix`/bin/ctags”
And now back to coding:

$ ctags -R
ctags: Warning: ignoring null tag in public/audio/audio-player.js
Dont forget to save ctags alias, ie like this:

$ alias ctags >> ~/.bashrc
And yes, homebrew rocks!
