Specifying Languages Using Aspect-oriented Approach: AspectLISA

Object-oriented techniques and concepts have been successfully used in language specification and formalization. They greatly improve modularity, reusability and extensibility. In spite of using OO paradigms in language specification, some semantic aspects still crosscut many language constructs. Improvements can be achieved with aspect-oriented techniques. The paper describes AspectLISA tool wich uses aspect-oriented approach for language specification (aspect-oriented attribute grammars). An example will be worked out in order to illustrate the approach. We will show how to identify an aspect, specify it in the concrete AspectLisa syntax, and how to gather parts in order to develop a complete language processor
