Backtrace

BACKTRACE IF RELEVANT

[TheBB]

Yes, there's no company backend for coffeescript. If you find one, do let us know.

When I M-x invoke company-mode in coffee file, it realy works. So I think company-mode has support it, we just need to enable it?

[TheBB]

You're getting the basic autocompletion then, I believe, not semantic. Not sure how useful that is, since it's pretty straightforward and knows nothing of the language you're writing.

[huaoguo]

If you write coffeescript,you will know it is useful.

[syl20bnr]

We can add company to the coffeescript hook then.

Cool @syl20bnr

[JuanCaicedo]

On the latest develop, I see company-disabled with coffescript by default. How do I add it to the coffeescript hook like you mentioned @syl20bnr ? Or should it already be enabled by default and I'm seeing a bug?

I tried adding (add-hook 'coffee-mode-hook 'company-mode) to dotspacemacs/user-config, is that correct?
