[MacRuby-devel] Creating ruby objects in Objective-C

Hi, Is there any way to inform an Objective-C class of the existence of a ruby class so that instances can be created in Objective-C code? Currently I am doing the following: [[MacRuby sharedRuntime] evaluateString:[NSString stringWithFormat:@"RubyClass.new('%@')", arg]]; If I'm adding quite a few objects (300+) to an array in a loop, this line of code is quite slow. My assumption (which may be false) is that either of the 3 options below would be quicker. [RubyClass performSelector:@selector(new:) withObject:arg]; [RubyClass new:arg]; [[RubyClass alloc] initWithArg:arg]; Are any of those options (or an equivalent) a possibility? Alan
