ReverseFuck

ReverseFuck is a Brainfuck modification created by Juraj Borza in 2006, which uses "reversed" brainfuck operators. This means that operator + acts as -, < acts as > and vice versa. The reason for this is that brainfuck may be too easy to understand for people, as + increments the current cell and > increments the pointer. But when this is reversed, it is harder to make sense of it.

Instructions: -	Increments the current cell (under the pointer). +	Decrements the current cell (under the pointer). >	Decrements pointer. <	Increments pointer. .	Inputs a character to current cell. ,	Outputs a character from current cell. ]	While the current cell value is not zero, do stuff inside ] and [ braces [	End while.

To compile ReverseFuck programs into Brainfuck and vice versa, you can use the converter. With a Unix-like shell, you can also use:

tr "\-+><.,][" "+\-<>,.[]" foo.b
