Abstract

Languages and systems to support generative and transformational solutions have been around a long time. Systems such as XVCL, DMS, ASF+SDF, Stratego and TXL have proven mature, efficient and effective in a wide range of applications. Even so, adoption remains a serious issue - almost all successful production applications of these systems in practice either involve help from the original authors or years of experience to get rolling. While work on accessibility is active, with efforts such as ETXL, Stratego XT, Rascal and Colm, the fundamental big step remains - it's not obvious how to apply a general purpose transformational system to any given generation or transformation problem, and the real power is in the paradigms of use, not the languages themselves.

In this talk I will propose an agenda for addressing this problem by taking our own advice - designing and implementing domain specific languages (DSLs) for specific generative, transformational and analysis problem domains. We widely advise end users of the need for DSLs for their kinds of problems - why not for our kinds? And we use our tools for implementing their DSLs - why not our own? I will outline a general method for using transformational techniques to implement transformational and generative DSLs, and review applications of the method to implementing example text-based DSLs for model-based code generation and static code analysis. Finally, I will outline some first steps in implementing model transformation DSLs using the same idea - retaining the maturity and efficiency of our existing tools while bringing them to the masses by "eating our own dogfood".
