Source lookup for word under cursor

[Ben Rady]

I've been messing around with a way to quickly lookup source from vim. What I've got here is something that will pull the current word under the cursor when you hit <leader>v (my leader key is comma) and use the gem command to find the corresponding file in a gem. It then opens that file in a new tab. It falls down in a few places, but it's a good start.

function! OpenRubySource()
  let class_name = expand("<cword>")
  let ruby_file = system("gem which ".class_name)
  exec "tabe ".ruby_file
endfunction

nmap <Leader>v :call OpenRubySource()<cr>

Is there already a plugin that does something like this? I did some searching before diving into this but I didn't find anything.

Ben,

Have you taken a look at ctags?  It's a very mature tagging tool with a vim plugin.  Here's a few links related to using it in vim with ruby (which I haven't personally done).
