Subject: [PATCH v5 1/9] submodule: add a print_config_from_gitmodules() helper
Date: Mon, 17 Sep 2018 16:09:32 +0200	[thread overview]
Message-ID: <20180917140940.3839-2-ao2@ao2.it> (raw)
In-Reply-To: <20180917140940.3839-1-ao2@ao2.it>

Add a new print_config_from_gitmodules() helper function to print values
from .gitmodules just like "git config -f .gitmodules" would.

This will be used by a new submodule--helper subcommand to be able to
access the .gitmodules file in a more controlled way.
