ctags definitions for Coffeescript. Very basic for now. "> ctags -e -R source_folder" and then M-. to jump to the definition of any function or variable (if you're using emacs)

Coffeescript ctags

--langdef=coffee
--langmap=coffee:.coffee
--regex-coffee=/^[ \t]*([A-Za-z.]+)[ \t]+=.*->.*$/\1/f,function/
--regex-coffee=/^[ \t]*([A-Za-z.]+)[ \t]+=[^->\n]*$/\1/v,variable/

Thanks for this great post.

I'm currently using vim and was wondering if you knew of a way to gave these tags listed in tagbar or taglist (http://majutsushi.github.com/tagbar/ or http://vim-taglist.sourceforge.net/). I'm currently resorting to basic vim tag usage which allows me to hop around tags but doesn't allow me to easily visualize all the tags available to me.

Hi, I'm happy you found this useful. I'm afraid I've never used Vim so can't help you out there :-/

Thanks! Also, the full identifier regex is [a-zA-Z_$][0-9a-zA-Z_$]* and functions can be bound (=> instead of ->).

Feel free to fork it! :)

To make ctags use these rules automatically, just add the lines above to ~/.ctags

To make the generated tags available in vim's TagList, add this line to your .vimrc

    let g:tlist_coffee_settings = 'coffee;f:function;v:variable'

Hopefully that answer dimroc's question.

This is one helpful example. The above notes for vim+tlist also helped a lot.

For others that find this gist and want more --regex-coffee to add to their ~/.ctags, take a look here:

👍 @benjie

I've added these 2 lines to ~/.ctags (after the lines which benjies pasted above)

--regex-coffee=/[ \t](.*\.)?([A-Za-z_0-9]+[ \t]=.*\))/\2/f/ 
--regex-coffee=/^([A-Za-z_.0-9]+[ \t]=.*\))/\1/f/

That allows completion out of the box in vim without snipMate:

in insertmode, after typing few characters, ctrl-x ctrl-] will popup any matching function with arguments

Very important to include

'(tags-case-fold-search nil)

This will make the tag search case sensitive, and that makes quite a bit of difference to navigation(reduces extraneous matches). Also, make sure to --exclude=anything_you_don't_care_about.
