* MacRuby integration with Xcode relies on rb-nibtool, but the Xcode team has repeatedly signaled (not so subtly) that they are not interested in keeping this shim working.

I assume that rb-nibtool scans rb files to identify possible IBOutlet and IBAction targets. If this is it's only function then I would not miss it if it goes away. I have discovered that it is easy to define IBOutlet and IBAction targets in Objective-C files without recoding any ruby code into Objective-C. The results are much better because the linkage and error messages are very fast while the scanning of ruby files gets very slow on a large project.

To avoid adding a lot of files, I created a single Objective-C .h and .m file for each of my nib files, including the main, giving it a corresponding name.

@property (weak) IBOutlet id example_menu;

- (IBAction)makeNewEngine:(id)sender;

#import "MainWindow.h"

@implementation AppDelegate

@synthesize template_menu;
@synthesize example_menu;

- (IBAction)makeNewMachine:(id)sender {};
- (IBAction)makeNewEngine:(id)sender {};

@end

The IBActions are easy. I simply define empty methods for my actions. MacRuby will replace the empty methods with the ruby methods.

For each IBOutlet, I define a C property, remove the attr_writer or attr_accessor from my ruby class, then reference the property from my ruby class using the dot syntax.

For this example, I changed @template_menu to self.template_menu and @example_menu to self.example_menu:

# attr_writer :template_menu, :example_menu

@mail_bridge_window_controller = nil


self

engines = bundle.pathsForResourcesOfType( "engine", inDirectory:"Templates" )
engines.each do | path |
title = path.split( '/' ).last.split( '.' ).first
item = self.template_menu.addItemWithTitle( title, action:"open_engine_template:", keyEquivalent:"" )
item.setTarget( self )
end
