OpenStack + pre-commit⌗

Many OpenStack projects, including Ironic and many SDK and oslo projects, now utilize pre-commit to perform linting at commit time.

This tool has a major downside: git hooks have to be enabled locally. If you’re someone who can easily forget things, and works in many diverse repos, this can lead to not utilizing this tool, which is unfortunate.

Luckily, I’ve found a solution! Templates are supported for git configs when you git clone or git init a repo, these are located. This means we can enable a pre-commit hook by default in all our repos:

git clone https://opendev.org/openstack/ironic ironic
cd ironic
pre-commit install
sudo cp .git/hooks/pre-commit /usr/share/git-core/templates/hooks/

This means every new cloned or initialized git repo on this system will have the pre-commit hook by default. This means you get an non-fatal error on repositories with no pre-commit config – no big deal for me.

Hope you find this trick helpful!
