I tried checking E201 and E241 of flake8 but ruff couldn't catch them and were fixed by black.

Both rules are marked as preview, so I assume they will only be enabled in the next ruff release: https://docs.astral.sh/ruff/rules/#error-e

That makes sense. But I tried some stable ones (E501 and E703), failed to catch them also. @SAMAD101 can you check if this is working for you?

[shivansh02]

Also since more than half of the pycodestyle rules are still in preview, should we enable ruff's preview mode or wait for them to get stable before trying to replace flake8?

Might be because it had to configured in ruff.toml Works fine now. Checked

Those seem to be working fine as well.
You can check them using: ruff check src/ --preview --select <rule_code>

You should reset your fork's master brach to upstream since it is diverged for a long time already.

Just to be clear slow linting isn't a problem we have. So this change should also simplify the config in some way or make it easier to run.

yeah, it does somewhat simplify the cofigs. And linting is just as easy to run as it was, we can use pre-commit or 'ruff check'
