Domain specific aspect languages (DSALs) are languages specifically designed for a domain with aspect-oriented features, obtaining benefits such as productivity and expressiveness. To embed a DSAL in an aspect-oriented general purpose language may present some advantages. To achieve this, one of the techniques used is language extensibility. XAJ (eXtensible AspectJ ) is an extensible language based on AspectJ, the main aspect-oriented language. The definitions of extensions to the language are modular, being encapsulated in a syntax class. Syntax class allow users define the syntax and semantics of a new construction, and represent it in the abstract syntax tree (AST ). The definition of the semantics of a new construction is given by the translation to already known constructs. At this point, the language can benefit from the advantages of metaprogramming. Metaprogramming is a technique of writing programs that generate or manipulate other programs. Metaprogramming commands are very ease to understand especially when they use a syntax that is very similar to the concrete syntax of the language. With an extensible metaprogramming mechanism, user defined constructs can be used in the definitions of new constructs. This work presents an extensible metaprogramming mechanism for the XAJ language, presenting examples of usage and its advantages.
