How to use it in Github Actions?

[provokateurin]

Hi, I'm trying to use commitlint in Github Actions to validate commit messages in the CI. For some reason I can't get it to fail when it should. The current workflow is at nextcloud/neon@a32ce68. I was able to get it working locally with https://github.com/nektos/act when using --from=main --to=@, but that also didn't work on Github Actions. Can someone help me get this working? I'm not sure if the workflow is the problem or if there is a bug in this tool.

You can see the configuration in this repo https://github.com/hyiso/commitlint/blob/main/.github/workflows/pr_title.yml

That only validates the PR title but I can't get it working with the commit range of the PR

I've added a Github Action in this repo and created a PR to test it #8.

From The Action Running Log, the problem happened during getting commit messages in Github Action Runner, which seems to be not related to this package:

commitlint:read - from = main, to = feature/validate-pr-commit, edit = null
commitlint:read - git log --format=%B main..feature/validate-pr-commit
commitlint:read - stdout = 
commitlint:read - stderr = fatal: ambiguous argument 'main..feature/validate-pr-commit': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

Thanks for the investigation. Can we still try to fix it here? I already tried things like fetching the whole repo or pulling the main branch etc.

Can you try

      - uses: actions/checkout@v3
        with:
          fetch-depth: 0

After several tries, the following configuration works finally:

uses: actions/checkout@v3
        with:
          fetch-depth: 0
          ref: ${{ github.head_ref }}
...
dart run commitlint_cli --from="origin/${{ github.base_ref }}" --to="${{ github.head_ref }}"

You can see the log https://github.com/hyiso/commitlint/actions/runs/5560955537/jobs/10158300171?pr=8

The important parts are checkout with ref and --from with origin/ prefix

[provokateurin]

Thanks a lot! I'll try it out on my repo. I think ref: ${{ github.head_ref }} is not necessary for this to work.

[provokateurin]

Ok I was wrong, you need to set ref. It works in my repo too! Maybe you can also add an example to show how to set it up.

It works, but if someone creates a PR from a fork then it doesn't work because the branch can't be found :/
