git submodule foreach - Robust way to recursively commit a child module first?

Question

Is there a robust way to do a recursive depth-first git submodule foreach command? I am using the foreach --recursive command which does the job, except it is breadth-first. This is a problem because if I have the following structure:

• A
  • B
• C

And I have commits in all three, a foreach --recursive add -A && git commit ... will hit A, B, C, which is problematic if I want the supermodule to capture the commits of B at that time.

I found this discussion from 2008, but it does not look like any of the suggested features are in the current version of Git that I have (1.7.9.5).

I wrote a small bash function to do this (excuse the shorthand naming):

function git-sfed() { git submodule foreach "git submodule foreach '$*' && $*"; }

And testing it with the following fanciful command seems to work:

git-sfed 'python -c "import sys; print sys.argv" $path'

Does this command seem robust, or are there other common existing methods?

Answer 1

You can try this

git submodule  foreach --recursive  |  tail  -r | sed 's/Entering//' | xargs -I% cd % ; git add -A & git commit

This list (recursively) all the submodules , then reverse the list, tail -r so you get the directories in the order you want (child first), enter the directory and do what ever you want in it.
