GS Commit Message Checker

A GitHub action that checks that commit messages match a regex patter. The action is able to act on pull request and push events and check the pull request title and body or the commit message of the commits of a push.

On pull requests the title and body are concatenated delimited by two line breaks.

Designed to be very flexible in usage you can split checks into various workflows, using action types on pull request to listen on, define branches for pushes etc. etc.

Configuration

See also action definition and the following example workflow.

More information about pattern and flags can be found in the JavaScript reference.

flags is optional and defaults to gm.

excludeDescription, excludeTitle and checkAllCommitMessages are optional. Default behavior is to include the description and title and not check pull request commit messages.
