Awesome that you did this! Thanks!

I left some comments to simplify the code.

Thank you also for your code suggestions - the changes have been implemented.
This was my first GitHub workflow that I worked on. Perfect issue to get me started! ;)

Maybe I should add a diff or other output step after README creation to show the differences/results?

I thought about that. In general it's a good idea, so let's keep the git diff action there.

But then I also thought: why not let the action update the README in the pull-request? This way the author of the PR doesn't have to check the diff and correct it, it get's corrected automatically.

Could you therefore try this push-action?

      - name: Push README
        uses: github-actions-x/commit@v2.9
        with:
          commit-message: 'update ${{ matrix.roles }} readme'
          rebase: true
          files: roles/${{ matrix.roles }}/README.md

With omitting the branch, it should push top the branch where the action gets executed. With omitting the author, it should use the author for the PR, I hope.

You or I could also do this in another PR, if you want to get this merged, first!

[Nemental]

great thoughts, thanks! I would like to test this myself. I gratefully accept any opportunity to practice GitHub workflow. 😄✌️

[Nemental]

Damn, okay, now it has to work :D

[rndmh3ro]

Maybe just run a git diff without any arguments?

[rndmh3ro]

Seems that pushing to a fork is not easily possible. So instead, let's just push to the master branch when the action is running from master, like you initially did.

[Nemental]

No, I don't want to give up yet. As I can see from the logs, the branch name is the problem. Give me one more try.
I also removed the diff-step, which would no longer be necessary if push worked.

Why does commit-action want to use 705/merge as branch name...

[Nemental]

This PR will be my personal nemesis.

The action is running in the dev sec orga, not in your fork. So it checks it out as the number of the PR. The /merge is to show that your changes are merged into master before running the action.

If github.head_ref with default github.ref_name don't work, I don't know anymore.

Property name	Type	Description
github.head_ref	string	The head_ref or source branch of the pull request in a workflow run. This property is only available when the event that triggers a workflow run is either pull_request or pull_request_target.
github.ref_name	string	The short ref name of the branch or tag that triggered the workflow run. This value matches the branch or tag name shown on GitHub. For example, feature-branch-1.

Thanks! Let's see what happens!
