#!/bin/sh

# how to use:
# put  all of this in some directory (eg.  /home/micah/bin/superproject-post-push.sh) and then do this in the git  submodule directory:
# micah@minnow:~/leap/puppet/modules/apt$ git config alias.xpush "push && /home/micah/bin/superproject-post-push.sh"

# use git xpush for pushing

# this assumes a couple things:
# 1. you do the commit in the top level of the submodule (not any subdirectory within)
# 2. you have no local, uncomitted changes in your superproject when you do any submodule commit

# exit on any error
set -e

# change this variable to your superproject checkout
superproject=${HOME}/leap/puppet

submodule_base=`basename $PWD`
submodule=${submodule_base#puppet_}

# check out the latest version of the superproject
# note: this part is fragile, because if you have local, uncomitted changes in your superproject, then this pull will fail
cd  ${superproject}
git pull
git submodule update --init

# check out latest version of submodule
# according to https://we.riseup.net/riseup+tech/puppet-git-submodules
cd ${superproject}/modules/${submodule}
git remote update
git merge origin/master

# commit and push the submodule update commit
cd ..
git add $submodule
git commit -m "automatic update of submodule $submodule_base"
git push
