How to lock commit if submodules have changed?

Question

Is it possible to lock the latch using the pre-latch hook if:

• Submodules have uncommitted changes
• Submodules do not change at least one remote
• Submodules are in a separate head state

Answer 1

Find uncommitted changes: git submodule -q foreach git status --short. If there is any conclusion - commit block.

Search untested changes: git submodule -q foreach git branch --verbose | grep "ahead\|behind".

Check the detached head: git submodule -q foreach git rev-parse --symbolic-full-name HEAD. If there is at least one "HEAD" in the output-block command.
