Syntastic unable to detect type on javascript file.

[fizzy123]

Hi! I've been using Syntastic for many years now and have enjoyed it. On this newest computer, I am encountering a strange new error. Syntastic doesn't seem to be able to identify the language on a javascript file.

When i open a javascript file and type :SyntasticInfo, I get the following:

Syntastic version: 3.10.0-32 (Vim 802, Darwin)
Info for filetype:
Global mode: active
Filetype  is active
The current file will be checked automatically
Available checkers: -
Currently enabled checkers: -
syntastic: 12.572107: &shell = '/bin/zsh', &shellcmdflag = '-c', &shellpipe = '2>&1| tee', &shellquote = '', &shellredir = '>%s 2>&1', &shelltemp = 1, &shellxquote = '', &autochdir = 0, &shellxescape = ''

When I check :SyntasticInfo javascript, I get the following:

Syntastic version: 3.10.0-32 (Vim 802, Darwin)
Info for filetype: javascript
Global mode: active
Filetype javascript is active
syntastic: 88.255584: system: command run in 0.590837s

which implies to me that syntastic is successfully finding checkers for javascript.

Any ideas on what else i could try? Thanks!

Syntastic doesn't seem to be able to identify the language on a javascript file.

That's Vim's job, not syntastic's. It's up to you to make sure all files have the proper filetype set before being checked by syntastic. One way to do it if Vim's autodetection fails is to put something like vim: filetype=javascript in a comment, near the top or bottom of the relevant files (cf. :h modeline).

That helped my issue. Seems like some versions of OSX don't have filetype enabled by default? I added the following to my vimrc:

filetype plugin indent on

And that fixed it. Thanks!
