the syntastic plugin is unhappy with a default mix.exs

[killerswan]

These errors (on opening the file, or saving) seem unfortunate:

Error detected while processing function <SNR>55_BufWritePostHook..<SNR>55_UpdateErrors..<SNR>55_Cache
Errors..240..239:
line    5:
E691: Can only compare List with List
E15: Invalid expression: status < 0

E712: Argument of filter() must be a List or Dictionary

That's on OS X with syntastic 3.6.0-130 (master, here) and Mix 1.0.5, after typing:

mix new portal --sup
gvim portal/mix.exs

After, also, enabling the syntax checker with these in my .vimrc:

let g:syntastic_elixir_checkers = ['elixir']
let g:syntastic_enable_elixir_checker = ['elixir']

Those functions are from syntastic. You should open this issue there. 😄

What's the version of Syntastic where this Elixir checker works for you, @kassio? I'll install that if you know it. :)

[kassio]

Actually I'm not using syntastic. 😊 But the function mentioned on the error 55_BufWritePostHook, it's from syntastic.

I've poked around under the hood enough now. If syntastic had this patch, I'd not have complained:
vim-syntastic/syntastic@master...killerswan:checker_enable_typecheck

And would have realized I needed this, instead:

let g:syntastic_elixir_checkers = ['elixir']
let g:syntastic_enable_elixir_checker = 1

:D

[kassio]

@killerswan nice! Now you just need to open a pull request there. 😄
