Versioned hooks for this repo. Enable them once per clone:

git config core.hooksPath .githooks

Runs git-clang-format (clang-format 19, using the repo .clang-format) on the staged lines only and re-stages the result, so every commit is clang-format-clean and the CI format check passes. It never reformats the whole tree, only the lines you changed.

• Disable for a single commit: HTTRACK_NO_AUTOFORMAT=1 git commit ...
• If clang-format 19 isn't installed, the hook skips silently (CI still enforces). Install it with your distro's clang-format-19, or from apt.llvm.org.
• If a file has both staged and unstaged changes, the hook does not auto-mutate it (that would commit the unstaged part); it instead reports whether its staged lines need formatting and asks you to stage/stash the rest.

Git executes the hook directly, so if your working tree is on a noexec mount git cannot run .githooks/pre-commit. Point core.hooksPath at a copy on an exec filesystem instead:

mkdir -p ~/.httrack-hooks && cp .githooks/pre-commit ~/.httrack-hooks/
chmod +x ~/.httrack-hooks/pre-commit
git config core.hooksPath ~/.httrack-hooks
