RubyMotion

 

RubyMotion - Wat?

/ˈro͞obē-mōSHən/

noun trademark
1. A proprietary toolchain, created by HipByte SPRL, for developing native iOS, OS X, and Android applications on mobile devices and computers by statically compiling the Ruby programming language.

OR

Apps the Ruby Way

Quick Example

Objective-C button tap


  [button addTarget:self action:@selector(buttonTapped:) 
    forControlEvents: UIControlEventTouchUpInside];
  //  Elsewhere
  - (void)buttonTapped:(id)sender {
      self.view.backgroundColor = [UIColor redColor];
  }           

RubyMotion button tap


  button.addTarget(self, action:'button_tapped', forControlEvents:UIControlEventTouchUpInside)

  # Elsewhere
  def button_tapped
    self.view.backgroundColor = UIColor.redColor
  end         

Better Example

Objective-C button tap


  [button addTarget:self action:@selector(buttonTapped:) 
      forControlEvents: UIControlEventTouchUpInside];

  //  Elsewhere
  - (void)buttonTapped:(id)sender {
      self.view.backgroundColor = [UIColor redColor];
  }
            

RubyMotion button tap (with RedPotion gem)


  find(button).on(:tap) do
    self.view.backgroundColor = color.red
  end

and more like_ruby

- Clay Allsopp

What about Swift!?

Swift is great ... but.

Ruby is Evolving

Ruby is Chosen

Ruby is Everywhere

What's So Great About RubyMotion?

In my opinion

  • Gems and Community
  • Editor Independence
  • Testing!
  • Readability
  • Natively Compiled
  • The REPL

RubyMotion Analogy

RubyMotion is to Objective-C


 

As Coffeescript is to Javascript

... plus RMQ is kind of like jQuery

... plus MacBacon has spec tests like Jasmine would

... plus the REPL lets you live-modify like developer tools

... plus CDQ gives you a DB like CouchDB would

... plus it compiles and obfuscates your final codebase

 

... OK, this analogy got out of control

 

Let's Look At Code!

  • Classic - Hello World
  • Full App - Ruby Trivia
  • Games!

Hello WorlD App Delegate

 

 

 

 

 

 

 

 


  class AppDelegate < PM::Delegate
    def on_load(app, options)
      open HelloWorldController.new(nav_bar: true)
    end
  end

Hello WorlD

 


 class HelloWorldController < PM::Screen
    def on_load
      p "Hai"
    end
  end  

SImply prints "Hai"

 

We can add a label to the screen just as easily.

Code Example #2

Ruby Trivia

  • RedPotion
  • BubbleWrap
  • motion-concierge
  • and more ...

Now using Redpotion

Tests!

Let's look at the code!

Code Example #3

Game Dev

Totally Tacos!

A game made in one day!

Alternatives?

Native

Stuck on Language
No Cross Platform

Phonegap

Slower
Insecure
Half-assed

Other?

xamarin
Facebook REACT NATIVE
