How do I trigger a Github action if a file is not touched?

Question

I would like to trigger a Github action if the Pipfile is not touched.

I can do something like

on:
  push:
    branches:
      - master
    paths-ignore:
      - Pipfile*

but if a PR touches the Pipfile along with another non-Pipfile file, then the action triggers.

Is this possible?

To be sure that I understood you. You want to have workflow run when non-Pipfile is changed, right? — Krzysztof Madej

I want to have a workflow run when a Pipfile is not changed. It is a subtle difference but it matters. — Kent Shikama

Can you elaborate more? For instance with example folder/file structure? — Krzysztof Madej

Two files: Pipfile and foo.py. If only foo.py is modified, then action triggers. If only Pipfile is modified, then action doesn't trigger. If both foo.py and Pipfile is modified, then action doesn't trigger. — Kent Shikama

I'm afraid that this is not possible. You can only break a workflow if Pipefile is changed. — Krzysztof Madej

This is not possible, but what you need is actually a check step to see what file was changed and then exit workflow if Pipfile was changed. You can do this using this command

git diff-tree --no-commit-id --name-only -r ${{ github.sha }}

This triggers even if the Pipfile is modified, which is not what I want.
