Have you looked at SuperC for inspiration? An example:
https://github.com/jeapostrophe/superc/blob/master/tests/superc/math.rkt /Jens Axel 2017-07-04 22:52 GMT+02:00 spearman <pearman...@gmail.com>: > I have built up a good toolchain for C programming including static > analysis and runtime testing tools, but I find the C preprocessor is really > lacking for metaprogramming facilities. > > Here is an implementation of "Lisp" macros for C: > https://github.com/eudoxia0/cmacro > > It doesn't seem to be actively maintained and a bit buggy (weird > formatting errors), and, well, it's Common Lisp :\ > > I made a start on converting the above into Racket: > > https://github.com/spearman/rcmacro > > At this point it is little more than a main module with command-line > options and stubs for the rest of the implementation. > > Two sticking points so far are error handling and finding a replacement > for the "packrat parser" (esrap) that cmacro relies on, as highlighted > here: https://github.com/eudoxia0/cmacro/blob/master/src/parser.lisp#L290 > > If there is something available for Racket along the same lines as esrap, > which uses TDPL grammar, I may be able to move forward with adapting this > code, otherwise it might be a lost cause and better off just coming up with > something from scratch (and I might learn something in the process). > However it seems like a large task and I would be essentially starting from > first principles. > > Before I make a choice on whether to proceed, I wanted check first if > there are already any Racket-based (or Scheme-based!) implementations of > macros for C. > There is this Racket implementation for C++: > > https://github.com/elfprince13/RacketMacros4Cxx > > but it requires a custom llvm/clang build, and the "demos" don't look very > much like what I had in mind. > > Mostly what I am looking for is a Scheme-like "macro-by-example" syntax to > provide some level of syntactic information (and hopefully hygiene) above > what the C preprocessor gives, but not necessarily full-blown "cooperating" > (MTWT) Racket macros. > > Comments/suggestions are appreciated. > > -- > You received this message because you are subscribed to the Google Groups > "Racket Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to racket-users+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- -- Jens Axel Søgaard -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
