pre-commit

#!/bin/bash
# Author: Nikolaos Dimopoulos
# Based on code by Remigijus Jarmalavičius
# Checks the files to be committed for the presence of print_r(), var_dump() and die()
# The array below can be extended for further checks

# Bruno's modifications:
# - Adds some JS checkup
# - Enable checkup in more languages
# - Fix the bug on the git status command
# - Add ESLint
# - Removes useless logs
