Scarecrow in the hillock
Paddy field --
How unaware!  How useful!

Passing through the world
Indeed this is just
Sogi's rain shelter.

A wild sea-
In the distance over Sado

What is this?

This little script lets you easily define a few things you want from a web page (using CSS selectors), the crawl the site until you get them all.

It's based on the way Kimono works, but it's much simpler and has no limit to the number of results you can get. It also uses your auth tokens from the browser, so it's just as secure as your browser (which you should still be suspect of).

How do I use it?

Put that script into your browser terminal and run it. If you use Chrome, I highly recommend saving it as a snippet for easy reuse. To start scraping a site, create a Scraper instance with your desired options:

var app = angular.module('myapp', ['ionic', 'firebase'])

app.controller('ctrl', function($scope, $firebaseArray) {

  // create a connection to Firebase
  var baseRef = new Firebase('https://webapi.firebaseio.com/rolodex');
  // create a scrollable reference
  var scrollRef = new Firebase.util.Scroll(baseRef, 'name');

  // create a synchronized array on scope

	document.addEventListener('DOMContentLoaded', noop);

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).
