This simple example actually has a lot of complexity, so I ll take it line by line, starting with the require at the top. You ll see that require 'osx/cocoa' is at the top of every RubyCocoa project. It hooks you up to the Objective-C runtime and dynamically generates the Ruby interface into the Cocoa classes. These classes, as well as all other exposed functionality, are available through the OSX module.

But you re still not quite ready to start using Cocoa yet. You first need to retrieve your application object. Calling the class method sharedApplication of NSApplication returns the singleton object that represents the current application. It also connects to the OS X windowing environment. So far, so good, right But what s up with line 3 It starts out like standard Ruby, using the NSWindow class from the OSX module. But what is this alloc method And why is initWithContentRect_styleMask_backing_defer named so weirdly

Figure 5-18. The default user jobs configuration screen Here you need to give a meaningful name to the user job, for example permanently remove cut list items, and then enter the previous command line in the command textbox. You can read more about setting up user jobs in the Setting Up the User Jobs section later in this chapter.

It s time to do a quick overview of Objective-C and Cocoa. Unlike Ruby, versions of Objective-C prior to 2.0 are not garbage collected. This means memory is managed manually. In other words, every time you create an object, you must at some later point explicitly delete it. This can be tricky to keep track of, which is why most languages are garbage collected these days. The garbage collector does the work for you. With that said, if you ve only ever managed memory in C (using malloc and free), you re in for a surprise. Life with Objective-C is a definite step forward. Allocation is performed using a class method (object-oriented how about that for a C-based language ) named alloc. Memory can be explicitly freed using dealloc. But

has_many :workouts, :dependent => :destroy has_many :exercises, :dependent => :destroy, :order => 'name asc' has_many :activities, :through => :workouts ( .remainder of User model ommitted for brevity)

Objective-C objects also support manual reference counting. When you re done using an object, you can call the release method to decrease its reference count. If you d like to hang on to an object (for example, in an add method of a collection class), you can call retain, which will increment the reference count. If the reference count ever hits 0, the object is deallocated. Here are some examples (written in real Objective-C, so you can get a look at the syntax which turns out to be important).
