Embedding attribute grammars and their extensions using functional Zippers
| Resumo: | Attribute grammars are a suitable formalism to express complex software language analysis and manipulation algorithms, which rely on multiple traversals of the underlying syntax tree. Attribute Grammars have been extended with mechanisms such as references, higher order and circular attributes. Such extensions provide a powerful modular mechanism and allow the speci cation of complex computations. In this work we de ned an elegant and simple, zipper-based embedding of attribute grammars and their extensions as rst class citizens. In this setting, language speci cations are de ned as a set of independent, o -theshelf components that can easily be composed into a powerful, executable language processor. We have also developed techniques to describe automatic bidirectional transformations between grammars. We de ne a method to de ne transformation speci cations which, through our automatic mechanisms, are inverted and expanded and generate attribute grammars that specify a bidirectional environment. We have implemented several real examples of language speci cation and processing in our setting, some of which are presented in this work. We have also developed and implemented a DSL using our technique for embedding attribute grammars, which we have deployed in a web portal for software analysis. |
