Agenda

• Apple and Ruby: a love story• Cocoa development with Ruby!• Demos!• Q&A

Apple ♥ Ruby

• 2002: Ruby 1.6.7 enters Mac OS 10.2• 2005: Ruby 1.8.2 enters Mac OS 10.4

• 2007: Ruby 1.8.6, RubyCocoa, RubyGems, Rails enter Mac OS 10.5

• In the future... Rails 2.x, Passenger, MacRuby

Our Goal

Making Mac OS X the best platform for Ruby developers

Our Goal

Making Ruby a first class citizenin Mac OS X

Our Goal

Making Ruby a first class Cocoa programming language

in Mac OS X

Why Ruby?

• Cocoa is mostly implemented in Objective-C• Objective-C and Ruby are conceptually very similar

(SmallTalk inheritance)

こういうのを見てると「RubyでOS

Xで(or のために)作られたんじゃないだろうか」と感じてしまう

After seeing this (Ruby in OS X), we end up feeling "Wasn't Ruby made on

(or for) OS X?"

RubyCocoa

• A bridge between C / Objective-C and Ruby 1.8• Created in 2001 by FUJIMOTO Hisakuni• Bundled and supported since Mac OS X 10.5• Stable

Mac development with Ruby?

Web development with Ruby?

Why?

• Cocoa is hard to apprehend for Ruby developers• Ruby 1.8 and RubyCocoa have performance and design

issues to be used inside Cocoa

RubyCocoa Hello World

require 'osx/cocoa'; include OSX

app = NSApplication.sharedApplication

win = NSWindow.alloc.initWithContentRect_styleMask_backing_defer( [0, 0, 200, 60], NSTitledWindowMask|NSClosableWindowMask|NSMiniaturizableWindowMask|NSResizableWindowMask, NSBackingStoreBuffered, false)win.title = 'Hello World'

button = NSButton.alloc.initWithFrame(NSZeroRect)win.contentView.addSubview(button)button.bezelStyle = NSRoundedBezelStylebutton.title = 'Hello!'button.sizeToFbutton.frameOrigin = NSMakePoint((win.contentView.frameSize.width / 2.0) - (button.frameSize.width / 2.0), (win.contentView.frameSize.height / 2.0) - (button.frameSize.height / 2.0))button_controller = Object.newdef button_controller.sayHello(sender) puts "Hello World!"endbutton.target = button_controllerbutton.action = 'sayHello:'

win.displaywin.orderFrontRegardless

app.run


Why?

• Cocoa is hard to apprehend for Ruby developers• Ruby 1.8 and RubyCocoa have performance and design

issues to be used inside Cocoa

It’s a bridge!

Problem #1

Messaging syntax is different!

Problem #2

Ruby 1.8 has green threads and is not reentrant!

Problem #3

Both runtimes have differentgarbage collectors!

Problem #4

MacRuby

• Ruby 1.9 implemented on top of Core OS technologies• Objective-C runtime and garbage collector• CoreFoundation

• In development (0.4 very soon!)• First production-ready for the end of the year

• Meant to solve the Ruby 1.8 + RubyCocoa problems!

Where is the Bridge?!

• In MacRuby:• A Ruby class is an Objective-C class• A Ruby method is an Objective-C method• A Ruby object is an Objective-C object

これが成功すればRubyは名実ともにOSXの公式スクリプト言語とし

て定着するに違いない

If this (MacRuby) succeeds, there is no doubt Ruby

will establish itself, both in name and in reality, as the official scripting

language for OS X.

HotCocoa

• A thin Ruby layer on top of Cocoa• Builder-like API• Rich Kilmer is our hero

app.run

MacRuby in the Future

• Multicore support• JIT compilation• OSA+AppleEvent

Hello I’m a Mac?

In 2010, maybe...
