Ralative 1 Bit

Ralative 1 Bit is a variant of 1 Bit, a quarter byte made by user:Krolkrol that has unbounded memory.

Instructions

The instructions stay relativly unchanged from the original, the only difference is that '1' inverts the next bit instead of the other one which allows for unbounded memory.

Examples

Binary Hello, World! + Quine

Implementation

def interpret(code):
    cp = 0
    code = list(code)
    while True:
        if code[cp] == '0':
            return "".join(code)
        elif code[cp] == '1':
            if cp < len(code) - 1:
                if code[cp+1] == '0':
                    code[cp+1] = '1'
                else:
                    code[cp + 1] = '0'
            else:
                if code[0] == '0':
                    code[0] = '1'
                else:
                    code[0] = '0'
                
        if cp < len(code) - 1:
            cp += 1
        else:
            cp = 0
