commit-msg

#!/bin/sh
#
# Adds current branch name as a prefix for every Commit

# To enable this hook, rename this file to "commit-msg" and make sure it is executable

# Optionally you could specify a
# folder that contains a subtree
# and prefix every commit related
# to it with a special prefix, and
# otherwise fallback to original
# behaviour:
#
#SHARED=0
#for file in `git diff --cached --name-only`; do
#  if [ `echo $file | cut -c 1-6` == "shared" ]; then
#    SHARED=1
#  fi
#done
#if [ $SHARED == 1 ]; then
#  sed -i "1 s/^/[subtree-shared] /" $1
#else
#  ticket=$(git symbolic-ref HEAD | awk -F'/' '{print $3}')
#  if [ -n "$ticket" ]; then
#    sed -i "1 s/^/$ticket: /" $1
#  fi
