Ale: An error that should go silent

[sassanh]

Sometimes I get this on saving files (very rare in general, but often when I :Gwrite:

Error detected while processing function ale#events#SaveEvent[6]..ale#fix#Fix[25]..ale#job#Stop:
line    9:
E474: Invalid argument

I think even if it can't be avoided it should be silent and don't show error.

ALEInfo has paths of my computer I'm not comfortable to share. I also suggest removing those paths from it.

[w0rp]

You can redact paths before you share whatever output.

Do you have any steps for repeating that bug? That ought not to happen.

If it doesn't provide you the information you need then we can go with reproducing plan. I almost always get this error if I save file with :Gwrite from fugitive.

[w0rp]

If you can provide some steps for reproducing the bug, I'll have a look at this. Please also provide the full error message that you see, if there are any other lines output for the error message.

[sassanh]

There no more lines, that's the complete error message. What about making that error silent? I think it can be ignored.

This is the list of my python fixers for ale:

            \ 'python': [
            \   'autopep8',
            \   'isort',
            \   'remove_trailing_lines',
            \   {buffer -> {
            \     'command': '/usr/local/bin/add-trailing-comma --py35-plus --py36-plus %t',
            \     'read_temporary_file': 1,
            \   }},
            \   {buffer, lines -> map(lines, 'substitute(v:val, ''^\s*$'', '''', '''')')},
            \ ]

If and only if I remove autopep8, isort, and the custom add-trailing-comma fixers it doesn't raise the error. If only one of these 3 are there it always raises the error with :Gwrite.

[w0rp]

That error can certainly be fixed. I haven't looked at this yet.

[sassanh]

Great, I suggested making it silent in case it's not easy to fix.

[akinsho]

I also receive this error primarily when running the Gwrite fugitive command or on changing buffers (when I have autowrite set to on) when editing a file which uses prettier as a fixer(the only fixer i have enabled).
PS: just wanted to take the opportunity to also say thanks for the amazing plugin!!

[w0rp]

I should have fixed this now by just changing call jobstop(a:job_id) to silent! call jobstop(a:job_id).

[sassanh]

I tested it and it doesn't raise an error anymore. Thanks.
