[MacRuby-devel] MacRuby class inside obj-c

[Laurent Sansonetti]

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)];
