dco-sign-off

A pre-commit hook that automatically adds a DCO Signed-off-by` line to your commit messages using your Git committer identity.

Usage

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

- repo: https://github.com/nineyards-robotics/dco-sign-off
  rev: v1.0.0
  hooks:
  - id: dco-sign-off

Then install the hook:

pre-commit install --hook-type prepare-commit-msg

The hook runs at the prepare-commit-msg stage, so it needs the --hook-type flag since pre-commit defaults to the pre-commit stage.

How it works

When you make a commit, the hook checks if a Signed-off-by: line is already present. If not, it appends one using the name and email from your Git config (equivalent to git commit -s).
