Generation of Software Renovation Factories from Compilers - Sellink, Verhoef (ResearchIndex) When a compiler is designed carefully, it is possible to extract its grammar. We reengineer the extracted grammar to one that is geared towards reengineering. From this reengineering grammar we generate an architecture called a software renovation factory. This includes: generic analysis and transformation functionality and a native pattern language using the concrete syntax of the language for which the renovation is necessary. Moreover, we generate the grammar in HTML format so that reengineers can quickly understand the language. We applied our approach successfully to an exceptionally complex and large proprietary language.
