michaelkl / rubocop.rb

Created March 19, 2020 11:47 — forked from skanev/rubocop.rb

A Rubocop wrapper that checks only added/modified code

	#!/usr/bin/env ruby
	# frozen_string_literal: true

	# Source: https://gist.github.com/skanev/9d4bec97d5a6825eaaf6
	#
	# A sneaky wrapper around Rubocop that allows you to run it only against
	# the recent changes, as opposed to the whole project. It lets you
	# enforce the style guide for new/modified code only, as opposed to
	# having to restyle everything or adding cops incrementally. It relies
	# on git to figure out which files to check.
