You mean Ruby calling Objective-C? Once the MacRuby runtime is initialized, you can access all your Objective-C objects from Ruby. For example, if you have an Objective-C class named Foo, you can do `Foo.new', etc.
Another possibility is to pass your Objective-C objects to a Ruby method by using -[NSObject performRubySelector:]. ruby: class Foo def test(o) o.something end end objc: MyObject *o = [MyObject new]; // where o responds to -something MacRuby *runtime = [MacRuby sharedRuntime]; id foo_obj = [runtime evaluateString:@"new Foo"]; [foo_obj performRubySelector:@selector(test:) withArguments: o, NULL]; Check out the whole API here: http://www.macruby.org/trac/browser/MacRuby/trunk/include/ruby/objc.h Laurent On Apr 28, 2010, at 2:17 PM, Alexander von Below wrote: > Thanks a lot! > > I have looked at the EmbeddedRuby app, but I did not see the way "back". > Could you point me in the right direction? > > Alex > Am 28.04.2010 um 22:55 schrieb Laurent Sansonetti: > >> Hi Alexander, >> >> On Apr 28, 2010, at 1:49 PM, Alexander von Below wrote: >> >>> Hello, >>> >>> I have a conceptual question: >>> >>> Is it possible for an embedded ruby script running in MacRuby to call back >>> into my Cocoa Application easily?
