Hi Martin,
You are bringing a good point. One can certainly write Cocoa apps without
Xcode, it's far from a requirement.
I used to have a small section in the book that was showing you how to
create a UI with Interface Builder, load the Address People Picker view
widget, simulate the UI and save it as a nib called 'picker.nib' (xib files
have to be compiled).
You can then open vim, textmate or whatever editor you fancy, and type the
following code:
framework 'Cocoa'
framework 'AddressBook'
app = NSApplication.sharedApplication
controller =
NSWindowController.alloc.initWithWindowNibPath(File.expand_path('picker.nib'),
owner:self)
controller.window
app.run
Save the file in the same directly than your nib file and launch the script:
$ macruby picker.rb
(you can also compile the file using macrubyc)
You will notice that the UI launches and seems to work fine until you try to
type some text in the text input box. (the text will show in the terminal
and not the UI)
Really, what you want is to create a .app and everything will be fine, but
doing that manually isn't really straight forward.
Also, having to bind UI elements with classes, actions and outlet is a pain
if you don't use Xcode.
At the end of the day, or we have something like HotCocoa/Rucola which works
fine and can be an alternative to Xcode, or every time you will want to
write a Cocoa app, you will rely on Xcode.
I still hope that Rich and Eloy will be able to finish their tools on time
so I can have a section on Xcode alternatives, but to start with, I think
it's better to show the "standard" way to write Cocoa apps in MacRuby, and
that means using Xcode.
I'm also planning on having a section on apps without an UI and for that, we
won't need Xcode.
I hope that makes sense, thanks for your feedback.
