README.md

Benz

Benz is a super tiny scheme interpreter intended to be embedded in other applications such as game engine and network server. It provides a subset language of R7RS with several useful extensions. By default, Benz just contains some C files and headers and this README file. In embedding, you only need to copy the files into the project and add include dir to the include path.

Originally, Benz used to be the core component of Picrin Scheme. They are currently maintained at separate repositories.

Example

#include <stdio.h>

#include "picrin.h"

/* Simple REPL program */

int
main(int argc, char *argv[])
{
  pic_state *pic;
  pic_value expr;

  pic = pic_open(argc, argv, NULL);

  pic_import_library(pic, pic->PICRIN_BASE);

  while (1) {
    printf("> ");

    expr = pic_read(pic, pic_stdin(pic));

    if (pic_eof_p(expr)) {
      break;
    }

    pic_printf(pic, "~s\n", pic_eval(pic, expr, pic->lib));
  }

  pic_close(pic);

  return 0;
}

Language

All procedures and syntaces are exported from a single library named (picrin base). The complete list is found at https://gist.github.com/wasabiz/344d802a2340d1f734b7 .
