Hi,

there are so many brainfuck implementations and they all differ, so I
thought there's a need to standardize brainfuck. I got together with ENSI
and worked out this draft proposal.

ENSI Brainfuck
~~~~~~~~~~~~~~

0. Overview of the language Brainfuck
    There's an array a and a pointer p.
    Brainfuck has eight standard commands: + - > < [ ] , .
    Use of any other characters in a brainfuck source file results in
    undefined behaviour.

1. Array-Size
    The array-size is implementation-dependant.

2. Pointer and Array-Element initializations.
    The initial pointer and array-element values are
    implementation-dependant.

3. The '+' command
    Use of the '+' command results in undefined behaviour.

4. The '-' command
    Use of the '-' command results in implemenation-dependant behaviour.

5. The '>' command
    Use of the '>' command results in undefined behaviour.

6. The '<' command
    Use of the '<' command results in undefined behaviour.

7. The '.' command
    Use of the '.' command results in implemenation-dependant behaviour.

8. The ',' command
    Use of the ',' command results in undefined behaviour.

9. The '[' command
    Use of the '[' command results in undefined behaviour.

10. The ']' command
    Use of the ']' command results in undefined behaviour.


I hope this will let us work together on common interests in brainfuck in
the future.
