GolferNightmare

GolferNightmare is an esoteric programming language by User:Dragoneater67. As its name implies, it was meant to make code golfing difficult.

Overview

The program has access to a tape of unbounded nonnegative integer cells initialized to all 0s. The tape infinitely expands to the right direction. There is also a tape pointer that initially starts on the first cell and a 1-bit IO register initially set to 0. Instructions are executed left-to-right in an implicit infinite loop.

Instruction table

Instruction	Description
>	Move tape pointer right, then increment current cell.
<	Increment current cell, then set tape pointer to 0.
/	Increment current cell, if current cell is not equal to next cell, skip to after the next occurrence of /.
~	Toggle IO register.
.	If IO register is 1, input an ASCII character, then add its ASCII code to the current cell, else, output current cell's value mod 256 as an ASCII character.
Anything else	Do nothing.
