Git pre-commit hook to prevent pry stuff from getting into the codebase

pre-commit.sh

# Git pre-commit hook to check all staged files for pry references

PRY_PATTERN="require.+[\'\"]pry[\'\"]|binding\.pry"

# Redirect output to stderr.
exec 1>&2

if git diff --cached | grep '^\+' | grep -q -E $PRY_PATTERN; then
	echo "ERROR: There is left over pry stuff in this commit"
	git diff --cached --name-only | xargs grep -n -H -E $PRY_PATTERN 
	exit 1 # reject 
fi
exit 0

Adding console.log and debugger would be useful as well.

And :focus respectively focus: true, of course.

I've done something similar with eslint

#!/bin/zsh

function lintit () {
  OUTPUT=$(git diff --name-only | grep -E '(.js)$')
  a=("${(f)OUTPUT}")
  e=$(eslint -c eslint.json $a)
  echo $e
  if [[ "$e" != *"0 problems"* ]]; then
    echo "ERROR: Check eslint hints."
    exit 1 # reject
  fi
}
lintit

useful for the console stuff and to check your code style etc.
