Boo Boo Kitty Fuck

Boo Boo Kitty Fuck is a feline variant of Brainfuck.

Source Code

A Boo Boo Kitty Fuck program is a single JPEG or PNG file which contains a gallery of cat images laid out in a rectangular grid. The image grid is processed starting in the upper left corner, proceeding left-to-right and top-to-bottom. The images represent Brainfuck operators as follows:

Brainfuck Operator	Boo Boo Kitty Fuck Operator	Meaning
>		Increment the data pointer.
<		Decrement the data pointer.
+		Increment the byte at the data pointer.
-		Decrement the byte at the data pointer.
.		Output the byte at the data pointer.
,		Accept one byte of input, storing its value in the byte at the data pointer.
[		If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
]		If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.

Usage

The bin directory contains the following tools:

bbkf

If the program requires any input, it will be read from STDIN.

echo "test" | ./bin/bbkf example/echo.jpg
test
