MacRuby in Action was written to give Rubyists the ability to create rich Cocoa applications
for the Mac OS X platform without having to learn Objective-C. Our goal is to
have you, the reader, creating amazing Cocoa applications using MacRuby by the end
of the book. Throughout the book, you’ll learn in the ins and outs of MacRuby while
exploring the Cocoa framework, design patterns, system scripting, testing, and getting
your application into the Mac App Store. We know that sometimes the best way to
learn is to get your feet wet. That’s why you’ll be creating useful Mac applications
along the way so you can apply the key topics as you learn them.
Who should read this book

This book is aimed at developers interested in writing software for the Mac platform.
It doesn’t matter if you’re new to both the Mac and the Ruby language or you’re an
experienced Ruby developer looking to learn how to write Mac apps. If you have the
desire to create beautiful Cocoa applications for the Mac platform and want to do so
using the elegant and highly productive Ruby language, then this book is for you. If
you’re new to Ruby, we give you a brief overview of the language so you’ll feel comfortable
enough to take on the rest of the book.
MacRuby in Action is also a more approachable introduction to Cocoa development
than traditional Objective-C books. Throughout the book, we explore practical code
examples that you’ll face when creating your own applications. MacRuby in Action can
act as a guide for using MacRuby and Cocoa from the ground up, or you can use it as
a reference if you’re looking to dive deeper into MacRuby.
