Infbf

Infbf is an esoteric programming language by User:Fyr. It is a derivative of brainfuck with an infinite-dimensional hypercube tape where each dimension has two cells.

The brainfuck commands > and < are repurposed as rotation to a different dimension, instead | is used for moving to the other cell in the current dimension.

A brainfuck program can be converted into an Infbf program by replacing each > and < with |> and <|.

Commands

Command	Description
>	Increment the dimension
<	Decrement the dimension
|	Move to the other cell in the current dimension
+	Increment the current cell
-	Decrement the current cell
.	Output a character from the current cell
,	Input a character and store it in the current cell
[	Jump forward to the matching ] if the current cell is zero
]	Jump back to the matching [ if the current cell is nonzero

Examples

A program that prints "Hello World!":
