M001 is not working

[adriangb]

With ruff v0.0.59 given a file like:

def foo() -> None:
    a = 1  # noqa: F401
    print(a)

Running:

ruff --extend-select M001 test.py

There are no errors

Interestingly I actually get:

∴ ruff --select M001 foo.py
Found 1 error(s).
foo.py:2:10: M001 Unused `noqa` directive for: F401
1 potentially fixable with the --fix option.

Does ruff --show-settings test.py have anything interesting?

[adriangb]

Oh duh user error, I had a config file floating around...

[charliermarsh]

Out of curiosity: what was the config file doing? Did it have an explicit ignore on M001? Something else?

Did it have an explicit ignore on M001?

Yes 🤦🏻 , I don't even remember why I put it in there. Embarrassing.

[charliermarsh]

Not embarrassing at all! It's bad that it was confusing for you as the user. If you explicitly --select something that's ignored by the config, we should warn you.
