Git pseudo post-push hook for updating supermodel when changes are made and pushed to submodule

Git post push hook for updating supermodule when submodule is updated

Create file named git-push-wh with the following content and add it to your path

#!/bin/sh

GIT_DIR_="$(git rev-parse --git-dir)"

BRANCH="$(git rev-parse --symbolic --abbrev-ref $(git symbolic-ref HEAD))"


POST_PUSH="$GIT_DIR_/hooks/post-push"


git pull --rebase origin $BRANCH
git push origin $BRANCH

test $? -eq 0 && test -x "$POST_PUSH" &&
    exec "$POST_PUSH" "$BRANCH" "$@"

chmod +x to the new file to make it executable
create the post-push hook by creating a file named post-push and adding it to the parent repo root .git/modules/themes/pfw-wp-puff-pastry-parent-theme/hooks with the following content:

#!/bin/bash
set -e

echo '-> Navigate to the repo root'
ROOT=$(git rev-parse --show-cdup)
if [[ '' != $ROOT ]]; then cd $ROOT; fi

echo '-> Check that this is a submodule'
echo `pwd`;
if [ ! -f .git ]; then echo "You must invoke me from inside a submodule."; exit 1; fi

echo '-> Get a reference to the current directory'
DIR=`pwd`
BRANCH=`git rev-parse --abbrev-ref HEAD`

echo '-> Get commit message'

MESSAGE=$( git log -1 HEAD --pretty=format:%s )

echo 'Your last commit message'
echo $MESSAGE
echo 'Will be used'

echo '-> Update supermodule (puffpastry repo) from submodule'
cd ../..

NEW_DIR=`pwd` 
git pull --rebase origin master

echo '-> Commit submodule change into puffpastry repo, in the master branch'
git add $DIR
git commit -m "$MESSAGE"
git push origin master

echo '-> Go back to where you came from'
cd -

git checkout $BRANCH

Again make the hook executable by running chmod +x post-push

Now you can push your changes to the submodule by running git push-wh from within the submodule directory and it will update the changes to the supermodule parent repo and push up to beansalk.
