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")

txus / transients.rb

Created September 19, 2013 10:54

Transients in Ruby. Transients are a way to mutate an immutable object for a limited scope of changes and then make it immutable again.

	class Object
	def transient(&block)
	dup.tap(&block).freeze
	end
	end

	str = "hey".freeze

	new_str = str.transient do \|mutable_str\|
	mutable_str.upcase!

chastell / unindent.rb

Last active June 14, 2016 17:24 — forked from avdi/unindent.rb

	TEXT = <<EOF
	See, the interesting thing about this text
	is that while it seems like the first line defines an indent
	it's actually the last line which has the smallest indent

	there are also some blank lines

	both with and without extra spaces in them

	and it just goes on and on
