Brain Ah Fuck or the full name brainahfuckohfuckwhydiditmultiplythevaluebytwopleasehelpmeihatethis is an esoteric programming language based on Brainfuck, but operating only on bits. It was made by User:Xarthan on June 2 2022 for only being pain.
Computational class
Brain Ah Fuck can be shown to be Turing-complete by reduction from brainfuck if I made it right.
Instructions
Brain Ah Fuck has the following commands:
| Cmd | Description |
|---|---|
s
|
Swap: sets 1 to 0 and 0 to 1 at the memory pointer |
0
|
0congoto: goto if 0 |
1
|
1congoto: goto if 1 |
>
|
Move right: Move data pointer right |
<
|
Move left: Move data pointer left |
.
|
Output: Output bit at data pointer |
,
|
Input: Input to data pointer moving right every bit |
Note: Trying to print any cell that is below id zero will halt.
Other note: Input starts at the least significant bit
Examples
Cat
A cat program writes its input directly to its output.
,<.0(2)1(2)
Hello, world!
A Hello, world! program is a trivial program which outputs a static string of text, usually
