Simple, single line output when there is a file with incorrect formatting

[Nogweii]

So that yamlfmt's output can be parsed by other tools to highlight which files need to be fixed, like reviewdog. Much like the existing -quiet flag, but without the preamble.

I'd imagine taking the existing -quiet output:

2024/02/28 15:23:20 The following files will have formatting changes:

foo/bar.yaml

and turning it into:

foo/bar.yaml: [warning] the file is not formatted correctly

(The exact wording is not required, just a demonstration.)

Hi @nogweii,

Thanks for the suggestion. It's not the first time someone's asked for something like this, I'll find a way to address it. I think I'll come up with some sort of adapter setup so it's possible to implement other kinds of output formats. Will work on this when I have time over the next week.
