Ruby: The future of frozen string literals

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

7 # integer literal

This list is based on aliases_spec.rb.

You can see also Module: RSpec::Matchers API.

matcher	aliased to	description
a_truthy_value	be_truthy	a truthy value
a_falsey_value	be_falsey	a falsey value
be_falsy	be_falsey	be falsy
a_falsy_value	be_falsey	a falsy value

rage-quit support for bash

HOW TO INSTALL

Due to the popularity of this Gist, and the work in keeping it updated via a Gist, all future updates will take place at the above location. Thanks!

Data visualization in one of three most important steps in data mining (https://github.com/entaroadun/hnpickup). Often times, it's impossible to understand data without proper visualization. I went looking for great tools to do that.

JS visualization frameworks

Two website list recent JS visualization frameworks:

	begin
	require "bundler/inline"
	rescue LoadError => e
	$stderr.puts "Bundler version 1.10 or later is required. Please update your Bundler"
	raise e
	end

	gemfile(true) do
	source "https://rubygems.org"

	#!/usr/bin/env ruby

	# 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.
	#
	# Here are some options you can pass in addition to the ones in rubocop:
	#

	require 'stringio'
	require 'timeout'

	class Object
	def methods_returning(expected, *args, &blk)
	old_stdout = $>
	$> = StringIO.new

	methods.select do \|meth\|
	Timeout::timeout(1) { dup.public_send(meth, *args, &blk) == expected rescue false } rescue false

	#Model

	@user.should have(1).error_on(:username) # Checks whether there is an error in username
	@user.errors[:username].should include("can't be blank") # check for the error message

	#Rendering
	response.should render_template(:index)

	#Redirecting
	response.should redirect_to(movies_path)
