问题 Alright, I've read the tutorials and scrambled my head too much to be able to see clearly now. I'm trying to capture parameters and their type info from a function signature. So given a signature like this: function(/*string*/a,b,c) I want to get the parts like this: type: string param:a param:b param:c This is Ok too: type: string param:a type: null (or whitespace) param:b type: null (or whitespace) param:c So I came up with this regex which is doing the common mistake of repeating the
