bfcc

bfcc is a brainfuck compiler. It compiles "ISO" brainfuck to a number of other targets. Currently only C99.

Future ideas

It would be nice to be able to create libraries through C, so we can invoke compiled brainfuck from Haskell.

Usage

bfcc "filename.bf" > myprog.c
gcc myprog.c -o myprog

You can also call bfcc without a filename, which turns it into a REPL translator, for example:

$ bin/bfcc
#include <stdio.h>
int main(int argc, char *argv[]) {
        char storage[32768] = {0};
        char *p = storage;
++
        // token: incr
        (*p)+=1;
        // token: incr
        (*p)+=1;
-
        // token: decr
        (*p)-=1;

To finish the output in REPL you must send the end of input signal (usually CTRL+D on *nix.)

Problems

• The array is fixed to 32768 bytes.
• There is no bounds checking, please don't use bfcc for your modern jetfighter avionics.

How to build

Run make, note that MSys or a Linux environment is needed for this Makefile.

It can be compiled manually in any case, just compile and link the files together.
