Install ctags in vim using home brew
brew install ctags
I have set up this mapping in my vimrc file for the ctags
<code>map &lt;C-F12&gt; :!ctags -R --exclude=.git --exclude=logs --exclude=doc . &lt;CR&gt;</code>
I just press <code>ctrl + fn + f12</code> and voilla I can use <code>ctrl + ]</code> to go the definition of function in a rails project.
The above did not find do tagging for gem specific functions.
I had to add
<code>bundle list --paths</code>
to the above line as well.
So now I have a new mapping which is something like this
<code>map &lt;C-F12&gt; :!ctags -R --exclude=.git --exclude=logs --exclude=doc . $(bundle list --paths)&lt;CR&gt;</code>
Now I go to a gem specific function and type <code>ctrl + ]</code> and voila I have migrated to the gem file and now I can have a look at the gem source.
