Description

@Pierre-Sassoulas I'm not sure if this warrants a changelog entry? I haven't added one.

I'll do a follow-up for epylint, as it requires some additional changes to its Run class.

Closes #5320

Oops, I based on the wrong branch. This should be better!

Great ! I think a changelog would be bice, if only to advertise the feature. I'll approve either way.

How do we call this?

"When invoking pylint, symilar or pyreverse programatically you can now pass an arguments keyword"? I'm really not sure...

"When invoking pylint, symilar or pyreverse programatically you can now pass an arguments keyword"? I'm really not sure...

Maybe : "The API of pylint, symilar and pyreverse now do not rely exclusively on sys.argv and also permits to pass args programmatically" ?

👌 You're doing so much lately, you're carrying 2.13.0 on your back 😄

I'm probably a bit late on this one.

I would suggest using args or argv instead, without the keyword requirement. This is what I usually see in these cases.

def main(argv: Optional[Sequence[str]] = None):
    argv = argv or sys.argv[1:]
    ...

Keyword only isn't really necessary here, it's just one argument. Even with more, the first will likely always be args / argv. More detail (optional) once can always be keyword only later, although even then not strictly necessary.
