[pro] Lisp and DSLs

[Alexander Repenning]

We have been working on what we call domain oriented languages for some time ranging from the first visual programming language for the MIT programmable brick (later Mindstorms) http://www.cs.colorado.edu/~ralex/papers/PDF/VL95-LEGOsheets.pdf

to AgentCubes (a 3D environment for end-users): http://www.cs.colorado.edu/~ralex/papers/PDF/AgentCubes_JVLC_article_inpress.pdf

Both of these programming environment are built in Common Lisp, are based on the concept of rules and have domain oriented interfaces to turn visual languages (via Lisp macros) into Lisp code.

Not sure this is what you are looking for but many people (teacher, students, ...) are using these kinds of domain oriented languages to build games and simulations: http://www.9news.com/news/local/article/202987/222/Teachers-play-video-games-for-science-
