Labyrinth

This is my 2d array-programing langauge. It's a WIP.

Your "Minotaur" starts at the upper-left corner of the program (0,0) with an initial velocity of one to the right. At the beginning of "round," every minotaur goesmy

Commands

Movement

Command	# of args	Description	Equivalent to
`	`	0	If moving vertically, whitespace; If moving horizontally, spawn another Minotaur and fork.
-	0	If moving horizontally, whitespace; If moving vertically, spawn another Minotaur fork.
>	0	Sets the velocity to 1 right
<	0	Sets the velocity to 1 left
^	0	Sets the velocity to 1 up
v	0	Sets the velocity to 1 down
{	0	Increase the velocity by 1 in the current direction
}	0	Decreases the velocity by 1 in the current direction; If this results in 0 velocity, the direction is swapped instead.
J	0	Steps an additional time, skipping what would be the next instruction.	1j
j	1	Steps n times

Control Flow

Command	# of args	Description
?	1	If the topmost element is falsey, turn 90º right.
I	1	If the topmost element is falsey, turn 90º left.
T	1	If the topmost element is falsey, pop the penultimate element.

Stack manipulation

Command	# of args	Description	Equivalent to
.	0	Duplicates the topmost element on the stack	1#
:	0	Duplicates the penultimate element on the stack	2#
#	1	Duplicate the nth element on the stack (topmost is 1)
,	0	Pops the topmost element off the stack	1@
;	0	Pops the penultimate element off the stack	2@
@	1	Pops the nth element off the stack
$	0	Swaps the topmost and penultimate elements on the stack	:3@
C	0	Pushes the length of the stack before C is executed

Math

Command	# of args	Description	Equivalent to
+	2	Adds the top two elements of the stack together
_	2	Subtracts the topmost element from the penultimate element
*	2	Multiplies the top two elements of the stack together
/	2	Divides the topmost element from the penultimate element
R	0	Pushes a random integer onto the stack
=	2	Pushes whether the top twomost elements are equal.
l	2	Pushes whether the penultimate element is smaller than the topmost element.
g	2	Pushes whether the penultimate element is smaller than the topmost element.
c	2	Pushes 1, 0, and -1 depending on how the penultimate element compares to the ultimate.
!	1	1 if the topmost element is 0 or an empty array; pushes 0 otherwise
X	1	Increment by one
x	1	Decrement by one

Integer <-> String functions.

Command	# of args	Description
A	1	chr; cast the topmost value as an char and create a string.
a	1	ord; cast the topmost value as a string and return the codepoint of the first element.
s	1	Converts the topmost element from an int to a string.
i	1	Converts the topmost element from a string to an int.

Array functions.

Command	# of args	Description
L	1	Pushes the length of the topmost element.
G	3	todo: explain more. (str[index..index+len])
S	3	todo: explain more. (str[index..index+len] = value)

I/O functions.

Command	# of args	Description	Equivalent to
P	1	Interprets the topmost value as a string, and prints it followed by a newline.	p10P
p	1	Interprets the topmost value as a string and prints it.
N	1	Interprets the topmost value as an integer and prints it, followed by a newline.
n	1	Interprets the topmost value as an integer and prints it.	n10P
D	0	Dumps the interpreter out and then exits.	dQ
d	0	Dumps the interpreter out.
Q	0	Exits with status code 0.	0q
q	1	Exits with status code n.
U	0	reads a line from stdin.
