Watch a file for updates to version number and then automatically adds a git tag

post-commit

#!/bin/bash

# Options
file="style.css"
prefix="Version:"

# Do not edit below
tag=$(git tag | tail -1)
version=$(grep -F  $prefix $file)
version=${version##*:}

function version { echo "$@" | awk -F. '{ printf("%d%03d%03d\n", $1,$2,$3); }'; }

if [ $(version $version) -gt $(version $tag) ]; then
	# Tag git with the new version number
	git tag $version
