[Feature] add option to ignore submodules

[rantoniuk]

Is this feature missing in the latest version?

• I'm using the latest release

Is your feature request related to a problem? Please describe.

It's great that the submodules are supported, but I would actually like to ignore submodules during the scans. This is because the changes for submodules should be normally managed in their own workflows, not in the target repository that is consuming them.

Currently I see in the logs:

Set 'fetch_additional_submodule_history: true' to fetch additional submodule history for: subm

Describe the solution you'd like?

I'd like to disable changed files detection in the paths defined by .gitmodules, e.g. ignore_submodules: true/false.

Describe alternatives you've considered?

I'm ignoring the submodule directory now via

files_ignore: |
  subA
  subB

but that doesn't improve the performance and it still shows the warning above. Also I need to maintain that list separately while it could be auto-populated from .gitmodules or from git submodule | awk '{print $2;}'.

Anything else?

Hi @rantoniuk you can now disable submodule diffs by setting the exclude_submodules to true using the latest https://github.com/tj-actions/changed-files/releases/tag/v44.1.0.
