INTRODUCTION This is a Nu implementation of a Domain Specific Language example that appeared in the following article by Martin Fowler: "Language Workbenches: The Killer-App for Domain Specific Languages?" http://martinfowler.com/articles/languageWorkbench.html This Nu version is adapted from a nicely-done Common Lisp version of the example by Rainer Joswig. After Rainer saw the Java and C# versions that Martin Fowler and others had done in the above article, he knew he could do better. Rainer has an article explaining his take on the example problem: http://lispm.dyndns.org/news?ID=NEWS-2005-07-08-1 Even better, watch Rainer's screencast in which he develops the solution from scratch in about 15 minutes using Common Lisp. http://www.cl-http.org:8002/mov/dsl-in-lisp.mov I ported Rainer's Common Lisp version to Nu as part of testing out the new macro-1 features in Nu 0.4. I added a simple dispatching mechanism and some sample debugging output as part of the code-generation in the macro. SYSTEM REQUIREMENTS This code requires Nu 0.4 or above. AUTHOR The original Common Lisp code was written by Rainer Joswig. The Nu version was written by Jeff Buck.
