This is a 2d esolang I made for fun, it is Queue based, it is hell

it also has multi threading by way of creating multiple pointers

the playfield scales based on the input (or at least it should, didn't test, didn't care)

Syntax

• ><V^ are used to move the instruction pointer around

• .> creates an instruction pointer moving to the right

• <. creates an instruction pointer moving to the left

• same works for up and down.

• ! skips the next instruction always

• ? skips the next instruction if the front of the queue is zero

• "FooBar" puts the ASCII values for FooBar on the queue

• 0 1 2 3 4 5 6 7 8 9 put that value on the queue

• p prints the first value as ASCII

• P does the same, but with a newline

• o outputs the first value as a number

• O outputs the first value as a number, with newline

• h outputs the first value as hex

• H outputs the first value as hex, with newline

• + - / * and % are supported, they take the first two values and apply themselves ([a, b] + [a + b])

• are ignored

• i reads the first char from stdin

• I reads an integer from a line in stdin

• # adds the amount of items currently in the queue to the end

• r recycles the first item in the queue (brings it to the back)

• R reverses the entire queue

• d duplicates the first item by dequeueing it and then adding it to the end twice

• D duplicates by peeking and then enqueueing once

• , allows for the construction of meeting points (,>,) where both pointers wait and then transfer the value according to the direction of the arrow

• inside a string you can escape values by using , only \", \0, \n, \r and \a are permitted because I could not be bothered to add more

• if a character is not recognized and the pointer is not in string mode, the program should throw

• x kills the pointer
