Our approach to teaching object-oriented programming focuses on conceptual modeling, emphasizing that object-orientation is not a bag of solutions and technology; rather, object-o...

Rewritable Reference Attributed Grammars (ReRAGs) is a recently developed compiler-compiler technology based on object-orientation, aspect-orientation, reference attributed grammars, and conditional rewrites. In this paper we describe our experiences from using ReRAGs for implementing Java compilers. We illustrate how the usage of ReRAGs renders a rather compact, yet easy-to-understand and modu...
