Writing a brainfuck interpreter is a lot fun: Mine does recursion within loops. I also added functions: strings, you can cheat. Stackdump(!), Exit script(*) , go to first cell (^), go to last cell(?), nulling cell (0) It parses this for example: "retoor" ^[.>]. It will dump string retoor. Explanation: the string moves ptr to sixth place. ^ will reset pointer to first. [] is a loop that executes as long there's data in current cell. The "." prints char of current cell (Number if not alpha etc). ">" moves a cell to right. [.>] will thus print until it moved to an empty cell. To move to first, I could've also used my repeater function by adding times to repeat after command: <6 moves six places to left. .>.>.>.>.>.> is also a way to print six chars. +[,.] works as the Linux program "cat". , is one char keyboard input.
