[PATCH] submodule--helper.c: add only-active to foreach

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Guillaume Galeazzi <guillaume.galeazzi@xxxxxxxxx>

On repository with some submodule not active, it could be needed to run
a command only for active submodule. Today it can be achived with the
command:

git submodule foreach 'git -C $toplevel submodule--helper is-active \
$sm_path && pwd || :'

Goal of this change is to make it more accessible by adding the flag
--only-active to the submodule--helper command. Previous example
become:

git submodule--helper foreach --only-active pwd
