[etc/vim.git] / scripts / check_pre_commit_rev_in_example.py
1 """
2 Check that the rev value in the example pre-commit configuration matches
3 the latest version of Black. This saves us from forgetting to update that
4 during the release process.

6 Why can't we just use `rev: stable` and call it a day? Well pre-commit
7 won't auto update the hook as you may expect (and for good reasons, some
8 technical and some pragmatic). Encouraging bad practice is also just
9 not ideal. xref: https://github.com/psf/black/issues/420
