Git Pre Commit Hook for FIXME TODO

pre-commit

#!/bin/sh

# An hook script to verify changes to be committed do not contain
# any 'FIXME:' comments. Called by "git commit" with no arguments.
#
# The hook should exit with non-zero status after issuing an appropriate
# message if it stops the commit.
#
# To bypass this hook, use the "--no-verify" parameter when committing.

# Redirect output to stderr.
exec 1>&2

# Define colors
RED='\033[0;31m'
NC='\033[0m'

# Define what term will be searched for.
SEARCH_TERM_FIXME="FIXME:"
SEARCH_TERM_TODO="TODO:"

# Check for the presence of the SEARCH_TERM in updated files.
if [[ $(git diff --cached | grep -E "^\+" | grep -v '+++ b/' | cut -c 2-) == *$SEARCH_TERM_FIXME* ] || [ $(git diff --cached | grep -E "^\+" | grep -v '+++ b/' | cut -c 2-) == *$SEARCH_TERM_TODO* ]]
then
	printf "${RED}Error:${NC} Found ${SEARCH_TERM_FIXME} | ${SEARCH_TERM_TODO} in attempted commit.\n"
	printf "Please remove all occurances of ${SEARCH_TERM_FIXME} | ${SEARCH_TERM_TODO} before committing.\n"
	exit 1
