This is the Esotope Brainfuck Compiler: the world's most optimizing Brainfuck-

to-something compiler. Well, it is not a Something-to-Brainfuck compiler like

Jeffry Johnston's BFBASIC, but it translates the Brainfuck code into efficient

target language code (and possibly human-readable), so in this sense it is

actually a _decompiler_ rather than compiler.

There are many Brainfuck-to-C compilers (or Brainfuck-to-ELF compiler, and so

on) available, but there are almost no compiler which can translate the

following Brainfuck code:

    >+++++++++[<++++++++>-]<.>+++++++[<++++>-]<+.+++++++..+++.>>>++++++++[

    <++++>-]<.>>>++++++++++[<+++++++++>-]<---.<<<<.+++.------.--------.>>+.

...into something like the following code:

    /* generated by esotope-bfc */

    #include 

    #include 

    #define PUTS(s) fwrite(s, 1, sizeof(s)-1, stdout)

    static uint8_t m[30000], *p = m;

    int main(void) {

        PUTS("Hello World!");

        return 0;

    }

Surprisingly I had seen no compiler reached this one! So I started to make my

own compiler; Esotope Brainfuck Compiler is the result. (Actually, there are

now one or two other compilers reached this state, but they are inspired by

Esotope Brainfuck Compiler.)

                                   HOW TO USE

                                   ==========

Esotope Brainfuck Compiler requires Python 2.5 or later. Optionally you can

use Psyco JIT compiler for better performance; Psyco is certainly required for

very large Brainfuck code, including Jon Ripley's The Lost Kingdom.

Use "esotope-bfc" Python script to invoke Esotope Brainfuck Compiler. It can

read the code from the given file, or standard input ("-"):

    $ ./esotope-bfc -

    +[]

    ^D

    /* generated by esotope-bfc */

    #include 

    #include 

    static uint8_t m[30000], *p = m;

    int main(void) {

        while (1); /* infinite loop */

    }
