Setup ctags on Mac for Rails development

The original ctags comes with Mac OS may say something like this when you run ctags -R:


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

To solve the problem, install a new version and disable the original one:

$ brew install ctags
$ cd /usr/bin/
$ sudo mv ctags ctags.orig

Then $which ctags will give you the new installed ctags in /usr/local/bin/ctags.
