ideasasylum / pre-commit

Created March 7, 2013 21:49

A pre-commit Git hook for preventing commits containing focus: true, debugger, binding.pry etc Based on a blog post I wrote http://jamie.ideasasylum.com/2013/02/preventing-the-stupid-mistakes-like-committing-focustrue/ (which in turn was based on someone else's script). This version allows you to easily setup new rules at the head of the script

	#!/usr/bin/env ruby
	spec_hits = []

	checks = {
	'_spec\.rb$' => ['focus:[:space:]*true'],
	'\.rb$' => ['binding\.pry', 'debugger']
	}

	# Find the names of all the filenames that have been (A)dded (C)opied or (M)odified
	filenames = `git diff --cached --name-only --diff-filter=ACM`.split("\n")
