Pre-commit hook to enforce use of feature branches and reject commits to master

pre-commit

#!/bin/bash

# This pre-commit hook prevents commits on branch '<forbidden_branch>' and enforces the use of feature branches.
# To use it in your repository, follow these steps:
#   1. Copy this file to `.git/hooks/pre-commit`
#   2. Make the file executable, e.g. via `chmod u+x .git/hooks/pre-commit`
#
# If one wants to commit to the '<forbidden_branch>' branch, the commit is rejected (script exits 1).
# The user is asked to create and checkout a new feature branch in order to proceed with the commit.
#
# The commit will be accepted if the script exits with 0
#

# Specify name of the forbidden branch inside quotes
forbidden_branch="develop"
