How to create small, unique tokens in Ruby

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

var Marquee = Class.create({

  initialize: function(element) {
    this.element = $(element);
    this.paused = false;

    // If everything fits don't bother with all this mess
    if(this.element.scrollWidth == this.element.clientWidth) return;

    // Defaults to scrolling through all content in 40 seconds.

A Note

Forking has been fixed, but the old repositories will still be corrupted.

Basics

The method page will create a new page: page "home" do "Hello, world!"
