Changelog Generator Github Action

Github action that creates a changelog upon PR opening. The changelog will contain all the commit messages grouped by type and change level (major, minor, patch).

Dependencies

To use this action, you need to use it together with action/checkout from github. We need that to access git changes. See usage example under.

How it works

Whenever you open a PR to master branch, action will compare master branch with your branch and post a comment to PR with all the changes that are going to be merged to master branch.

There are a few assumptions that you should be aware, when you're using this action.

Assumption

• You're release branch is master
• You keep clean commit history (ideally squashing your changes so each commit correspond to single change/feature)
• You follow one of the following conventions when writing your commit messages - gitmoji or conventional commits. It will work also without that, but your grouping for minor and major changes might be off. For more details, see how we detect changes below.
• Besides grouping per change severity, we also sub-group based on change type. That means that first word in commit will be also used to group the changes and order them.

Change level

Major change

Major change is considered every commit that:

• includes emoji :boom: or
• includes key work BREAKING CHANGE or BREAKING_CHANGE or
• first word of the commit contains !

Minor change

Minor change is considered every commit that:

• includes emoji :sparkles: or
• first word of the commit contains feat

Other changes

Every change that is not MAJOR or MINOR falls under other changes.
