A powerful macrolanguage for C.


LISP/c turns

(header stdio) (main (@printf (str "Hello, world!")) (return 0))

into (after it being cleaned up)

#include <stdio.h> int main(int argc,char **argv) { printf("Hello, world!"); return 0; }


(lisp/c-macro for-m (vars nums &rest body) (if (or (null vs) (null nums)) `(block ,body nil) ;; "NIL" to get rid of extra {}s `(for (var ,(car vars) int 0) (< ,(car vars) ,(car ns)) (++ ,(car vars)) ,(apply for-m (cdr vs) (cdr ns) body)))))
(for-m (i j k l m) (3 3 3 4 5) (@printf (s. "%d %d %d %d %d") i j k l m))
will compile to
for(int i=0;((i)<(3));++(i)) { for(int j=0;((j)<(3));++(j)) { for(int k=0;((k)<(3));++(k)) { for(int l=0;((l)<(4));++(l)) { for(int m=0;((m)<(5));++(m)) { printf("%d %d %d %d %d",i,j,k,l,m); }; }; }; }; }
