Elegant command-parsing in an OOP-based text game

Question

I\'m playing with writing a MUD/text adventure (please don\'t laugh) in Ruby. Can anyone give me any pointers towards an elegant, oop-based solution to parsing input text? <

Answer 1

The Interpreter design pattern is the most object-oriented approach to parsing that I'm aware of, but I'm sure compiler experts will point out algorithms that are more powerful.
