And by trying a bit I see blocks are not supported, am I right? 2010/5/18 Laurent Sansonetti <lsansonetti@apple.com>
Indeed, methods with normal arities (0..n arguments) conform to the Objective-C ABI, so using the bracket syntax just works. But for Ruby methods using complex arities (like splat or optional arguments), you will likely get a crash. This is why the -performRubySelector: method was introduced. It is better to always use that method, because it always works (in theory).

great! I can even seem to send messages directly to my MacRuby classes and instances... like: id obj = [Foo new:@"objc"]; and [obj hello];
but in the second case I get a compiler warning: "No -hello method found"??

Hi Louis-Philippe,
Assuming MacRuby code defines:
class Foo def initialize(message) @message end def hello puts "hello #{message}" end end
You should be able to retrieve a reference to Foo using:
Class Foo = [[MacRuby sharedRuntime] evaluateString:@"Foo"];
Or, more simply:
Class foo = NSClassFromString(@"Foo");
You might want to use the first way in case the class has a complex path (if it's defined inside modules, like "Foo::Bar").
Later, you can send messages to it.
id obj = [Foo performRubySelector:@selector(new:) withArguments: @"objc", nil]; [obj performRubySelector:@selector(hello)];

Hi, I don't know if this is the good list to ask this question as it is my first... So,
I saw how I can have a MacRuby cocoa app, importing objective-c classes. I can't find info on how to do the opposite... having an Objective-C cocoa app, importing and using MacRuby Classes...
All I managed to do is to "evaluateFileAtPath:" and "evaluateString:"
Thanks!
