How Should We Use Struct?

It's common in Ruby to see some code setup a Struct like this:

class Specialized < Struct.new(:whatever)
  # ... define custom methods here...
end

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	[1] pry(main)> Class.new.respond_to?(:define_method)
	=> false
	[2] pry(main)> Module.new.respond_to?(:define_method)
	=> false
	[3] pry(main)> Class.new.send(:define_method, :yup) {}
	=> #<Proc:0x00000100a08cb8@(pry):3 (lambda)>
	[4] pry(main)> Module.new.send(:define_method, :yup) {}
	=> #<Proc:0x00000100d8f468@(pry):4 (lambda)>

	[user]
	name = Ben Hyrman
	email = [email protected]
	[core]
	autocrlf = true
	editor = vim
	excludesfile = C:\\Users\\Ben\\Documents\\gitignore_global.txt
	[credential]
	helper = !~/AppData/Roaming/GitCredStore/git-credential-winstore
	[merge]

	define(function (require) {

	var module;

	// Setup temporary Google Analytics objects.
	window.GoogleAnalyticsObject = "ga";
	window.ga = function () { (window.ga.q = window.ga.q \|\| []).push(arguments); };
	window.ga.l = 1 * new Date();

	// Immediately add a pageview event to the queue.

	# So, this is pretty horrible. If we just encode using btoa, any UTF-8 chars cause an error.
	# If we use either of the workarounds on MDN[1], the £ sign is encoded wrong. I suspect
	# Excel totally sucking at encodings is the reason why. So, the workaround is, to use
	# the MDN workaround on chars with values > 255, and allow chars 0-255 to be encoded
	# as is with btoa. Note that if you use either of the workarounds on MDN, chars
	# 128-255 will be encoded as UTF-8, which includeds the £ sign. This will cause excel
	# to choke on these chars. Excel will still choke on chars > 255, but at least the £
	# sign works now...
