ruff is faster and handle everything we had prior. isort configuration done based on the indication from https://github.com/astral-sh/ruff/issues/4670, previousely based on reorder-python-import (#11896) flake8-docstrings was a wrapper around pydocstyle (now archived) that explicitly asks to use ruff in https://github.com/PyCQA/pydocstyle/pull/658. flake8-typing-import is useful mainly for project that support python 3.7 and the one useful check will be implemented in https://github.com/astral-sh/ruff/issues/2302 We need to keep blacken-doc because ruff does not handle detection of python code inside .md and .rst. The direct link to the repo is now used to avoid a redirection. Manual fixes: - Lines that became too long - % formatting that was not done automatically - type: ignore that were moved around - noqa of hard to fix issues (UP031 generally) - fmt: off and fmt: on that is not really identical between black and ruff - autofix re-order in pre-commit from faster to slower Co-authored-by: Ran Benita <ran@unusedvar.com>
