Hi all,
I have a somewhat esoteric problem and I was wondering if anyone had suggestions about how to deal with it.
Basically I'm writing a Ruby class that wraps some Objective-C classes and provides a common interface to them, and I'm using method_missing to pass along messages if the wrapped object understands them. This works great for simple methods that don't have named parameters. However, by the time a call hits method_missing, MacRuby has already converted the method signature to a Ruby-style call.
For example, one object I'm wrapping has a method "doScript:in:" - but by the time that hits method_missing I have a method with signature "doScript:" and a list of arguments like "script, {:in => target}".
Now of course, I can add some logic to my method_missing handler to check if the second param is a Hash and reconstruct the Obj-C method signature from that. I'm just wondering if MacRuby provides a built-in way to do that, or if I'm missing an easier way to handle this...
Any input appreciated!
Thanks,
