How can I turn off specific messages in syntastic (vim)?

Question

I'm trying to turn off some of the messages in syntastic.

For example, SC20148 in bash files (it complains there's no shebang).

After looking through the documentation, it seemed that perhaps this might be done through:

let g:synstatic_quiet_messages = {
  \ 'type': 'syntax',
  \ 'regex': 'SC20148' }

However this doesn't seem to work. How do I turn off specific messages?

Answer 1

The Devil is in the details:

1. the variable is actually called g:syntastic_quiet_messages
2. the error is actually SC2148
3. you probably don't want to disable syntax messages.

Thus:

let g:syntastic_quiet_messages = { 'regex': 'SC2148' }

Or just:

let g:syntastic_sh_shellcheck_args = '-e SC2148'

Answer 2

Turn off multiple kinds of warnings in syntastic in vim:

Add this line to your .vimrc

let g:syntastic_quiet_messages = { 'regex': 'SC2148\|SC1234\|SC6789' }

Also you can do it against the message itself like this:

let g:syntastic_quiet_messages = { "regex": 'superfluous-parens\|too-many-instance-attributes\|too-few-public-methods' }
