Advanced Commit Linter

Advanced Commit Linter is a GitHub Action that lint commit messages of PR. It checks for issue trackers and upstream references. Results can be displayed as a status check or Pull Request comment when used together with issue-commentator GitHub Action.

How does it work

TBA

Features

Tracker references validator
Upstream references (cherry-pick) validator

Usage

To set up Advanced Commit Linter, we need three files:

Workflow that captures Pull Request metadata (number and commit metadata) and uploads this data as an artifact
Workflow that runs on workflow-run trigger, downloads artifact, and runs advanced-commit-linter GitHub Action
advanced-commit-linter.yml configuration

Note

Setup is complicated due to GitHub permissions on GITHUB_TOKEN. When used in workflow executed from fork it has read-only permissions. By using the workflow-run trigger we are able to safely overcome this limitation and it allows us to comment on Pull Requests.
