This is a simple github action that is triggered on github PR merging that will increment the git tag on the merge commit following semver and add a comment to the merged commit with the new tag.

To use this, simply define an action configuration yaml in the .github/workflows directory of your repository with the following contents:

name: Auto Tagger

on:
  pull_request:
    types: [closed]

jobs:
  auto-tagger:
    uses: RueLaLa/auto-tagger/.github/workflows/auto_tagger.yml@master

The default Github token created for the action to use has enough permissions to checkout, tag, and push the new tag on the repo that this action is defined in.

To test the semver component locally, install the python dependencies by running pip install -r requirements.txt where auto-tagger is checked out.

Then, cd to the directory you want to test in and run the below command:

DRYRUN=True GITHUB_SHA=$(git rev-parse HEAD) /path/to/auto-tagger/entrypoint.py

Once installed, when merging a pull request, simply include either #major, #minor, or #patch to the commit message. Alternatively, if you don't include of these, a patch level bump will be assumed. Below is an example from the pull request page:
