macruby: ruby for your mac
DESCRIPTION
Everyone wants to develop Cocoa in Ruby. It can create awesome Mac apps. But you need to develop in Objective-C. Which is not so pretty. However, they both share some of the same concepts and ideas.RubyCocoa exists, but it's a bridge. So conversion is happening and that is slow and resource intensive. And each runtime has a different garbage collector!MacRuby interprets Ruby on the Objective-C runtime. Kinda like JRuby does with the JVM.All objects in MacRuby inherit from NSObject.HotCocoa is a thin Ruby layer on top of Cocoa. He showed some code and it really looked like Ruby. Slick desktops apps for the Mac written in Ruby are coming for Christmas (the projected "Production Ready" date of MacRuby).From the audience: "What about iPhone apps?"Laurent: (said in an outrageous French accent) "I'm sorry I can not answer this question"Watch a video at http://www.bestechvideos.com/2008/12/08/rubyconf-2008-macruby-ruby-for-your-macTRANSCRIPT

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

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

RubyCocoa Hello World
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

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.

• Multicore support• JIT compilation• OSA+AppleEvent
Hello I’m a Mac?
In 2010, maybe...
