# A hook to add [$branch] to the beginning of a commit message
# if certain conditions are met.
#
# This is a prepare-commit-msg hook.
#
# To install this you can either copy or symlink it to
# $GIT_DIR/hooks, example:
#
# ln -s ../../git-tools/hooks/prepare-commit-msg \\
#   .git/hooks/prepare-commit-msg
#
# Make sure it is executable.

# strip off ref: refs/heads/
branch="$(cat $GIT_DIR/HEAD | sed 's/ref: refs\/heads\///g')"

# * only run when normal commit is made (without -m or -F;
#   not a merge, etc.)
# * also make sure the branch name begins with bug/ or feature/
if [ "$2" = "" ] && [ $(echo "$branch" | grep -e '^\(bug\|feature\)/') ]; then
