flake8 ignores --config args

With the following config

    -   id: flake8
        args: ['--config=setup.cfg']

Any settings in setup.cfg are never read. Adding additional settings e.g. args: ['--config=setup.cfg', '--max-line-length=500'] will set max line length to 500 but will ignore anything set in setup.cfg.

It will also selectively ignore and choose some of your other settings so something more like this should work:

    -   id: flake8
        args: ['--config=setup.cfg', '--ignore=E129,E2']
        exclude: ...

Ah yes I’ve found this as well.

If you have this config:

[flake8]
exclude = foo/

and you run flake8 foo/bar.py it’ll still try and lint foo/bar.py

What we’ve been doing in our repos is not using flake8’s exclude but instead use pre-commit’s exclude:

   -  id: flake8
      exclude: ...
