MacRuby & RubyMotion - Madridrb May 2012

Transcript

1. MacRuby & RubyMotion Programming OS X and iOS apps with Ruby
2. Hi I’m @MarkVillacampa
3. Blame Him
4. MacRuby An implementation of the Ruby language that runs on top of the Objective-C runtime and garbage collection (libauto) Based on Ruby 1.9 Uses LLVM and supports both ahead-of-time and just-in-time compilation Ships with OS X 10.7 Lion!!
5. MacRuby Started by Laurent Sansonetti inside Apple Initial 0.1 release in March 2008 Latest stable release (0.10) March 2011 Nightlies are very stable (0.12) http://macruby.org/ https://github.com/MacRuby/MacRuby
6. Cocoa Apple's native object-oriented API for the Mac OS X operating system Foundation Kit + Application Kit + Core Data frameworks Cocoa Touch: Includes gesture recognition and different UI to use in iOS
8. How to install Install XCode (Mac App Store, Free) Install Command Line Tools (Preferences > Downloads) Install MacRuby Nightly If you are in OS X 10.6.8, install Bridge Support Preview 3 https://github.com/MacRuby/MacRuby/wiki/Setting-up-MacRuby
9. Key concepts: MacRuby objects are Objective-C objects >> "Hello Madridrb!".class.ancestors => [String, NSMutableString, NSString, Comparable, NSObject, Kernel] Can use Ruby & Cocoa methods >> "Hello Madridrb!".upcase <- Ruby => "HELLO MADRIDRB!" >> "Hello Madridrb!".uppercaseString <- Cocoa => "HELLO MADRIDRB!"
10. Key concepts: New method syntax: named parameters Cocoa classes need to be allocated and initialized >> NSString.alloc.initWithString(“Hello Madridrb!”) => "Hello Madridrb!" >> NSDictionary.alloc.initWithObjects(["foo"], forKeys: ["bar"]) => {"foo"=>"bar"}
11. 1. The syntax
12. Objective-C: Ruby: a = {"foo" => ["bar", "baz"], "oof" => 2} NSMutableDictionary *dict = [NSMutableDictionary dictionary]; [dict setObject:[NSArray arrayWithObjects:@"bar", @"baz"] forKey:@"foo"]; [dict setObject:[NSNumber numberWithInt:2] forKey:@"oof"];
13. Objective-C: Ruby: a = {"foo" => ["bar", "baz"], "oof" => 2} NSMutableDictionary *dict = [NSMutableDictionary dictionary]; [dict setObject:[NSArray arrayWithObjects:@"bar", @"baz"] forKey:@"foo"]; [dict setObject:[NSNumber numberWithInt:2] forKey:@"oof"];
14. 2. XCode
16. Interface Builder
17. 3. REPL Console ( Read Eval Pr int Loop )
19. 4. Gems
20. Any gem that works with Ruby 1.9 should work with MacRuby
21. 5. Behaviour-Driven Development
22. A small RSpec clone, with NSRunLoop powers. https://github.com/alloy/MacBacon MacBacon
23. 6. Mac App Store
24. http://briquetteapp.com/
25. http://shop.oreilly.com/product/ 0636920000723.do http://manning.com/lim/
26. RubyMotion Built on top of MacRuby Uses a new LLVM-based static compiler that generates optimized machine code Memory model similar to Objective-C ARC Based on Rake http://www.rubymotion.com/
27. RubyMotion Commercial product. Educational licenses available at discounted price. Laurent Sansonetti left Apple to work on it. Released May 3rd, 2012 Fast growing community!
29. HelloMadridrb app app_delegate.rb resources spec main_spec.rb .gitignore Rakefile $ motion create HelloMadridrb .rb files Main delegate Images, Sounds, .xib files Tests Configuration file
30. 1. Interactive Console
31. Holding and clicking in a UI element assigns that element to the self variable in the console
32. 2. CocoaPods
33. CocoaPods is like RubyGems but for Ojective-C projects. $ sudo gem install cocoapods $ pod setup $ sudo gem install motion-cocoapods Choose a pod: https://github.com/CocoaPods/Specs Edit Rakefile: require 'motion-cocoapods' Motion::Project::App.setup do |app| # ... app.pods do dependency 'JSONKit' end end
34. 3. TestFlight
35. TestFlight helps you distribute development builds of your app to your betatesters. $ sudo gem install motion-testflight Download TestFlight’s SDK and put it in the “vendor” directory inside your app. require 'motion-testflight' Motion::Project::App.setup do |app| # ... app.testflight.sdk = 'vendor/TestFlight' app.testflight.api_token = '<API token>' app.testflight.team_token = '<team token>' end http://testflightapp.com/sdk/download Edit Rakefile: $ rake testflight notes='First release!' Run:
36. 4. App Store
