Meta-programming Ruby for Fun & Profit
Location: Portland Ballroom 252 Audience level: Intermediate
This session shows one of the reasons that JRuby is the most powerful mainstream language today: meta-programming. It shows tons of meta-programming techniques in Ruby, including open classes, the shadow meta-class, defining methods, method_ & const_missing, dynamically adding and removing mixins, and more. And each of these comes with an example that actually makes sense!
