When using changie to generate your changelog, it is useful to be able to autogenerate a changelog file in the format expected by changie when a bot creates a PR. This action checks out the branch for the PR, creates a new changie yaml file, commits it and then pushes it to the PR.

A common use is PRs created by dependabot.

Automate changelog generation for more visability with automated bot changes.

Once a PR is created and it has been labeled as indicated. It will only create a new yaml file if none already exists on the PR.

An exampe use is for PRs created by dependabot. You can also manually trigger this by adding the specified label at any time.

• GITHUB_TOKEN: If you expect the resulting commit to add a changelog should retrigger workflows, you will need to use a Personal Access Token for the bot to commit the file. When using the GITHUB_TOKEN, the resulting commit will not trigger another GitHub Actions Workflow run. This is due to limitations set by GitHub. See the docs.
• commit_author_name: Author namw of the commit for the changelog file.
• commit_author_email: Email of the author of the commit for the changelog file.
• changie_kind: Type of changelog file # TODO: how does changie define this?
• label: GitHub label to trigger off

• commit_message:
  • description: Message to put on commit of new changelog file
  • default: "Add automated changelog yaml from template"
• custom_changelog_string: # is this the right way? could it be templated? start here and iterate.
  • description: The multi-line string containg the expected contents of the custom fields for a changelog entry.
