Is there a way of knowing if bump detected an increment?

[m0wer]

I would like to programatically disable subsequent steps in a workflow if no increment is detected in this action (If cz bump detects no increment).

Does it make sense to add an output variable that states whether or not an increment was detected or is there a simpler way of approaching this?

cz bump throws an error code different than 0, this means that most pipelines will be interrupted.

If you are writing a POSIX shell script, you can do something like:

#!/bin/sh -e

if cz bump; then
    echo 'it was bumped correctly'
else
    echo "there was an error, whose error code is $?"
    exit 3  # 3 is the error code thrown by no commits found
fi

Thanks for your answer @woile. Unfortunately, it looks like cz bump returns 0 even if no increment is detected. Example:

$ cz bump --changelog
bump: version 1.3.0 → 1.3.0
tag to create: 1.3.0
increment detected: None
$ echo $?
0

And the same result happens when using this action in a workflow: https://github.com/now8-org/app/runs/4832942786?check_suite_focus=true (check the commitizen step output).

Nice catch, it is actually a bug on commitizen, not on this github action, I've submitted a PR to cz.
An error code should be returned instead (I think). (If) Once merged, it should solve this issue.

commitizen-tools/commitizen#473

Thanks for reporting

Can you test with the latest version?
Thanks

It's working now. Thanks.

In case it helps anyone what I did to condition the execution of subsequent steps was:

      - name: commitizen
        id: commitizen
        continue-on-error: true
        uses: commitizen-tools/[email protected]
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}

     - name: Some other task
        if: steps.commitizen.outcome == 'success'
        run: something
