Case Studies

Abstract

Three case studies are presented in this chapter to show the use of the unparser-complete metalanguage and the usability of the syntax-safe template evaluator in a practical setting. The syntax-safe template evaluator Repleo is used for implementing these case studies. Two case studies show a reimplementation of an existing code generator. The reimplemented code generators use a separated model transformation stage, resulting in less code and better maintainable code than the original implementations. The use of separated model transformation stage is also enforced by the unparser-complete metalanguage of Repleo. The maintainability is achieved by less code clones in the code generator specification and less entanglement of metacode and object code. The third case study shows the benefits of syntax-safe templates in the context of dynamic web page generation. Syntax-safe templates provide a solution against cross-site scripting attacks.
