Gemlou.pe & Easymarklet

(And a mention of SimpleDB)

Gemlou.pe

What is it?

A way to judge the relative "weight" of a gem before adding it to your Gemfile.

Uses a bookmarklet to add new information to pages on RubyGems.org and Ruby-Toolbox.com.

bookmark + applet = bookmarklet

Javascript from your site that is injected (at user request) into a remote site.

XSS for fun and profit?

Use your power for good.

Easymarklet

easy + bookmarklet = Easymarklet

A gem to help you create bookmarklets for your Rails app.

gem 'easymarklet'

Extracted from a project that uses a bookmarklet.

Packages boilerplate code for setting up RPC channels.

Definitions

Consumer

Loaded into the remote page.

Producder

Loaded on a page in your app.

DLux Bookmarklet

rails g easymarklet:dlux gemloupe

Inject a "buffer" iframe into the remote page. Keeps the RPC channel open.

Put an iframe in that iframe. This is a navigable iframe that displays pages in your app.

Communication

Consumer -> Buffer -> Producer

Producer -> Buffer -> Consumer

Easymarklet Structure

Takes advantage of the asset pipeline.

Single "bookmarklet" JS file contains logic for both consumer and producer.

var RemoteLoupeBookmarklet = {
  visible : true,
  protocol : 'https',
  consumer : {
    css : ['/assets/remote_loupe_bookmarklet.css'], // could be an array or a string
    methods : { ... }, // The methods that the producer can call
    init : function(url,producer){ ... }
  },
  producer : {
    buffer : "/remote_loupe_producer/buffer",
    path : "", // Avoid a flash before the correct page is set by the client
    methods : { ... }, // The methods that the consumer can call
    init : function(){ ... }
  }
}
window.RemoteLoupeBookmarklet = RemoteLoupeBookmarklet;

SimpleDB

NoSQL style key value store.

AWS::Record::Model

ActiveModel style ORM.

gem 'aws-sdk'
class Loupe < AWS::Record::Model

  string_attr :name
  string_attr :version
  string_attr :state, :default_value => 'new'
  integer_attr :runtime_weight
  integer_attr :development_weight
  timestamps

end

And Finally

Completely unrelated to anyting....
