[Rubycocoa-talk] Calling Ruby from Objective-C

[Stefan M. <ste...@po...>]

Hello

	I have a question about calling Ruby methods from Objective-C.

	The Introduction from rubycocoa.com only shows you how to do this
	for a user-defined method that uses underscores.

	[helper helpfullyAddX:x toY:y]
		=>
	 def helpfullyAddX_toY(i,j)

	But how am I supposed to call a function like Object.instance_eval
	It takes multiple arguments, and has not enough underscores.
	It can also take a single block.

	obj.instance_eval ( aString <, file <, line> > )
	obj.instance_eval ( { block } )

	The bridge only tries to call the method with the block.
	So how do I call the other Version with 2 or 3 params?
	
	I've made a proxy method that's a better fit for bridge and then  
calls the Ruby method,
	but I don't think it's ideal.

	def evaluate_source(script, source)
		self.instance_eval(script, source)	
	end
