Ty! Output filters work great with pylint too; see https://www.jetbrains.com/help/pycharm/configuring-third-party-tools.html#pylint-configure

Using this config with file watcher:

Can flake8 be configured to run automatically in pycharm?

How can I use a flake8 config file (setup.cfg) together with the external tooling?

I think you can add the setup.cfg to the Parameters:

Parameters: -m flake8 --max-complexity 10 --ignore E501 $FilePath$

and use the $ProjectFileDir$ to locate your setup.cfg.

Thank's a lot, really helpful info! 👍

thanks for helps!!

Created a small repo for pycharm external tools (currently flake8 and black supported ) for applying to a code selection from pycharm.
Maybe this will be somewhat helpful to anyone: https://github.com/haim0n/pycharm_ext_tools

Thank you, @haim0n!

Thank you, worked like a charm!

Cheers , glad to help :)

Just bear in mind that flake8 deprecated the support for --diff option in its next versions: https://flake8.pycqa.org/en/latest/release-notes/5.0.0.html#deprecations
