Improve path

[mudlabs]

1. Allow path to be a glob
2. If the workflow that triggered the action is set to only run on an push or pr event to a specific path, is there a way this action can know that?
   • Under this use case, if the action can know the path, then the user would not need to specify the path input. Assuming that's the same path/file they want to diff.

Under development in the dev branch.

I've implemented number 2. if no path input is provided the action will find the workflow file and parse its contents for a paths array under the push/pull_request property. If it finds any it will use the first path (index 0).

It does not yet support glob strings.
