^@ in output (unwanted newlines)

[nomasprime]

Expected behaviour

Getting this output for inline error message:

expect(described_class.all.size).to eq(2)^@  expected: 2^@       got: 1^@  (compared using ==)

Inline error messages shouldn't have repeated whitespace or multiple instances of ^@. Output in quickfix doesn't but it does have other escaped output (see tpope/vim-dispatch#291).

"^@" are newlines. The maker could clean them up. IIRC some do so already, and there's a generic helper method for it (also IIRC).

[blueyed]

Which maker is it?
You can check running it manually - see the logfile (let g:neomake_logfile = "/tmp/neomake.log") for how it runs and what it gets.

[nomasprime]

Looks like the maker is makeprg. It's called from vim-test.

@blueyed any suggestions?

I'm curious, as messages are displayed inline, why removing these characters isn't applied to all makers?

[nomasprime]

Unfortunately I can't get any of the postprocess doc examples to work.

[nomasprime]

Finally got correct output with let g:neomake_postprocess = 'neomake#postprocess#compress_whitespace'.

No idea why this isn't the default.

[blueyed]

@nomasprime
Sorry for the trouble - I'm glad you've figured it out.
It should maybe get added to the docs at least - using it by default might not be desirable, e.g. for when you care about the newlines etc.
But it could be added for the "makeprg" maker's default then maybe or something similar.
