Is this something ctags itself would maybe need to support? When I run ctags -R . in the root of an Elm project, it only seems to generate tags for the (quite mangled) symbols in elm-stuff.

(For what it's worth, ctags --list-languages returns a list of languages it supports, and Elm does not appear in the list on my machine.)

For what it is worth, I have created a rudimentary ctags extension for Elm: ctags-elm. I have not done any sort of integration with elm-vim though.

Regarding ctags -R . picking up symbols in elm-stuff, that is an issue in ctags-elm too. For the moment, ctags -R src, avoids the problem. Still looking for a better solution.

Thanks @kbsymanz! I think that is a great start.

To solve your immediate problem, you can use ctags -R --language-force=Elm to filter just the elm files. You are still going to get the elm files in your tests and examples of course.

I have added preliminary tagbar support based on your elm .ctags file. I will keep an eye on the repo and update as you improve it.

That did not work for me. JS files still were found in the tags file. But I did eventually get this to work pretty well.

ctags -R --exclude="*.js" .

The --exclude option can be used repeatedly in order to eliminate other file types.

I was actually using the following, but saw the --language-force option at the last minute and misunderstood its meaning. It seems to work.

ctags -R --languages=-all,+Elm

Yes, that does seem to work well. Thanks.
