Passing variables to commit_message

[stevehillsTB]

First, thank you for a really excellent action. I appreciate you!

I was wondering if there is a way to pass variables to the commit_message argument. I can't seem to resolve variables such as default environment variable '$GITHUB_RUN_NUMBER'. For example:

 - name: Commit Build Number
   uses: stefanzweifel/git-auto-commit-action@v4
   with:
     commit_message: Build Number ${GITHUB_RUN_NUMBER}
     file_pattern: version.h

Thanks.

Best Regards,
Steve

Hi Steve,

This should definitely be possible.
I think this should be solvable by using contexts.

Maybe a simple change like the one below works for you?

- name: Commit Build Number
  uses: stefanzweifel/git-auto-commit-action@v4
  with:
    commit_message: "Build Number $GITHUB_RUN_NUMBER"
    file_pattern: version.h

I've also found the following StackOverflow questions/answers that seem to e similar to what you want to achieve:

• https://stackoverflow.com/questions/60347162/github-actions-env-use-pre-defined-environment-variables-on-rhs-within-env-sec
• https://stackoverflow.com/questions/60432844/how-to-perform-string-manipulation-while-declaring-env-vars-in-github-actions

Just to clarify: git-auto-commit accepts any message for the commit message and is not responsible of what is allowed or how that message is built. That "logic" is part of GitHub Actions itself.

Thank you, @stefanzweifel !

Your answer is correct, using the context property github.run_number allowed the run number to be resolved correctly.

- name: Commit Build Number
  uses: stefanzweifel/git-auto-commit-action@v4
  with:
    commit_message: Build Number ${{ github.run_number }}
    file_pattern: version.h

Best,
Steve
