commit message check

A pre-commit (project) hook to verify commit messages conform to a pattern. Specifically it checks that the first n commits on a branch fit the pattern (checking evey commit is trivial with pygrep) This uses the commit-msg stage hook, be sure you have installed that hook.

the length of which branch?

This tool assumes you are following the common convention of creating small feature branches from a default branch. The default branch is found by inspecting origin/HEAD, you can overwrite this with the arg -b=<some-weird-branch>.

usage

Here's an example .pre-commit-config.yaml which enforces the first 3 commits on a branch have a message starting like ABCD-001, TICK-33310
