RubyMotion Query: A jQuery-like library for RubyMotion

RubyMotionQuery - RMQ

A fast, muggle, nonpolluting, zero-dependency, jQuery-like library for RubyMotion.

The RMQ Introductory Guide and other info is a great place to start.

Some of the very cool features:

• selecting (querying) views
• traversal through view hierarchy (moving around the tree)
• tagging
• events and gestures
• animations
• stylers and stylesheets
• colors
• fonts
• image utilities
• app
• device

Tested on iOS, not OS X (nor is there any OS X specific code)

Other wrapper libraries

There are a lot of great wrappers out there such as Teacup and Sugarcube. I've used these and I enjoy them. However, many of the wrappers heavily pollute the standard classes, which is great if you like that sort of thing. RMQ is designed to have minimal pollution, to be very simple and high performance (it will be when it's done). RMQ shouldn't conflict with anything.

RMQ doesn't require any other wrapper or gem.

If you preferred jQuery over Prototype, you'll love RMQ.

Some of the code in RMQ came from BubbleWrap and Sugarcube. Not too much but some did. I thank you BubbleWrap and Sugarcube teams for your work.

Prerender: Let search engines crawl your JS apps

Prerender Service

This is a node server that uses phantomjs to render a javascript-rendered page as HTML. It should be used in conjunction with prerender_rails or prerender-node middleware to serve the rendered HTML to crawlers for SEO. You don't have to run this service on your own since I have it deployed on Heroku already. Get started in two lines of code using Rails or Node

It is also meant to be proxied through your server so that any relative links to things like CSS will work.

It is currently deployed at http://prerender.herokuapp.com, or you can deploy your own.
