Mukha

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

Mukha is one-dimensional esolang by User:ChuckEsoteric08 which is endowed with the faculty of boustrophedon motion across a one-dimensional program, while employing an integer-valued accumulator and a stack of integers for conditionally skipping instructions as well as realizing goto operations.

Commands

Command	Operation
+	add 1 to the accumulator
-	subtract 1 from the accumulator. If result was less than zero, skip next command
(	Push IP to the stack
)	Pop element from the stack, and set IP to it. If stack was empty do nothing
;	Pop element from the stack. If stack was empty, skip next command
:	Go back to the start of the program
>	move IP to the right
<	move IP to the left
\	if moving left skip next instruction
/	if moving right skip next instruction

Examples

Increment and decrement via a loop

The following program increments the accumulator to the value 3, then repeatedly decrements it in a loop until it reaches a negative state, finally exiting the program.

+++(-)

Increment from left to right, decrement from right to left

This program increments the accumulator to the value 3 while traveling in a sinistrodextral airt, then decrements it to 0 during its athwart traversal.

+\/-+\/-+\/-<

Increment accumulator forever

>+<
