clang-format mirror for checking diffs

Yet another mirror of the clang-format package for the pre-commit tool.

As opposed to https://github.com/pre-commit/mirrors-clang-format/ (which we forked from), this one verifies the diffs instead of whole files. You'd expect that from clang-format-diff, but the tool that does the work, comes with clang-format and nicely integrates with git is cleverly named git-clang-format, so this is what this repo's hook uses and hence this is how it's named.

Using git-clang-format with pre-commit

Add this to your .pre-commit-config.yaml:

-   repo: https://github.com/aostrowski/pre-commit-mirror-git-clang-format
    rev: ''  # Use the sha / tag you want to point at
    hooks:
    -   id: git-clang-format

Implementation details

The tags for each clang-format version are generated automatically using the pre-commit-mirror tool. You can see the command invocation in .github/workflows/main.yml.

As of writing this, the tool didn't yet support adding multiple hooks in one repo, so if you wish to add another one, either improve the tool or just create another fork.
