Visual language framework for LISA

Compiler construction is a difficult task. Therefore more suitable solutions than the existent ones are needed. In this paper a framework (domain-specific visual language) for visual language design is presented. The framework automatically generates the compiler/interpreter by using visual notation. The main advantage of this approach is the use of a more appropriate visual notation and abstractions in comparison to classical textual notation of formal language specifications for compiler generators. Special attention is paid to better flexibility and reusability of the predefined semantic constructs
