# Based on https://serebrov.github.io/html/2019-06-16-git-hook-to-add-issue-number-to-commit-message.html
#
# This hook works for branches named such as "123-description" and will add "#123 " to the commit message.
#
# 123-description >> #123
#
# Example:
#
# ``` 
# $ cd 123-description
# $ echo "commit msg" > foo
# $ sh .git/hooks/prepare-commit-msg foo
# $ cat foo
# #> #123 commit msg
# ```

# get current branch
BRANCH_NAME=`git rev-parse --abbrev-ref HEAD`

# search issue id in the branch name, such a "123-description" or "XXX-123-description"
ISSUE_ID=$(echo $BRANCH_NAME | sed -nE 's,(^[0-9]+)-.+,\1,p')

# only prepare commit message if pattern matched and issue id was found
if [[ ! -z $ISSUE_ID ]]; then
  # $1 is the name of the file containing the commit message
  echo -e "#$ISSUE_ID ""$(cat $1)" > "$1"
