ArrowQueue
- This article is not detailed enough and needs to be expanded. Please help us by adding some more information.
ArrowQueue is a two-dimensional esolang created by User:ChuckEsoteric08 inspired by Re:direction
Specification
ArrowQueue uses a single queue which stores Instruction Pointer's direction. There are following commands:
* - turn Instruction Pointer (IP) clockwise ~ - enqueue current direction + - dequeue element from the queue and set direction to it
Other characters are ignored. Program halts when it tries to dequeue from an empty queue or IP moves out of bounds.
Computational class
It is possible to translate Cyclic tag system into the language. 0 is encoded as (down, right) and 1 is encoded as (right, right). As an example here is Cyclic Tag program with initial data 1 and productions (011, 10, 101):
