I would like to use

--changed-since

in a GitHub Actions workflow to know if anything in Django has changed and use that to run subsequent steps conditionally. How can this be achieved best with

pants --changed-since=HEAD django::

Copy code

- name: Create list of changed docker images
        id: changed-since
        run: |
          pants --changed-since=HEAD --filter-target-type=docker_image list > changed_since.txt
          
      - name: Check for Changes in Django
        id: django-changed
        run: |
          grep -q "django" changed_since.txt && echo "any-changed=true" >> $GITHUB_OUTPUT || echo "any-changed=false" >> $GITHUB_OUTPUT
      - name: Conditional step
        if: steps.django-changed.outputs.any-changed == 'true'

Better ideas?

Not sure I understand what you're trying to do achieve, but would either of

--changed-dependees=transitive

and

--filter-address-regex='^django'

help you here?

I just would like to know if in my source root django any files have changed

Ok; and what's the relation to the docker images? 🙂 They seem to be tied together.

So for example

pants --changed-since=HEAD --filter-target-type=docker_image --filter-address-regex='^django/.*' --changed-dependees=transitive

should list: all docker images, where the address starts with

django/

, which have changed, or whose dependencies have changed, since the last commit.
