I provide ANTLR consulting expertise including ANTLR debugging, tutoring and optimization. From straight parsers and command line interfaces to code transformation and translation systems, I've taken ANTLR to its limits. Please email me for more information monty@codetransform.com
Browse my GCC translation framework at http://www.antlr.org/grammar/cgram or download it at http://www.antlr.org/grammar/cgram/cgram.tgz. It's a complete source to source transformation system based on antlr. Possible applications include extending the C language with type safe pointers, instrumenting code, implementing an Aspect Oriented compiler, source code analysis, or specialized debugging and profiling code generation. It's like having a compiler without the executable generations.
I also wrote an Advanced Revelations R/BASIC to Visual Basic translator to translate 240,000 lines of Arev code for the Harry and David catalog company's order entry system. I don't own the code I wrote for them but I know the translation strategy very well and would love to do such a project again. Email me if you are interested in me doing this for you.
I provide a good deal of free support as well. You can see what I've been up to recently from these links.
