Goatoo is an esoteric programming language created in May 2021. It is especially made for people who hate the goto command. The official interpreter is written in python and published on github under a GPLv3 license.

Language Overview

The language uses 2 different memory systems: a stack, containing ascii codes (up to 255), and a cell system, containing booleans. Goatoo has 23 commands:

Command	Description
:X	Go to line X
=X	Check if the ascii value of letter X is equal to the number at the top of the stack, and save the result to the cell at the pointer
~X	Check if the number X is equal to the number at the top of the stack and save the result to the cell at the pointer
!	Invert the state of the cell at the pointer (True <-> False)
>	Move the pointer right
<	Move the pointer left
?	Skip the next line if the cell at the pointer contains False
]	Output the symbol of which the ascii value is equal to the number on top of the stack
[	Get a symbol as input and save it's ascii value to the top of the stack
}	Output the number on top of the stack
{	Get a number as input and save it to the top of the stack
|X	Save the ascii value of symbol X to the top of the stack
(X	Save number X to the top of the stack
+	Pop the top two numbers on the stack, add them up, and save the result to the top of the stack
-	Pop the top two numbers on the stack, subtract the lower number from the top number, and save the result to the top of the stack
*	Pop the top two numbers on the stack, multiply them, and save the result to the top of the stack
/	Pop the top two numbers on the stack, divide the top number by the lower number, and save the result to the top of the stack
%	Pop the top two numbers on the stack, divide the top number by the lower number, and save the remainder to the top of the stack
\	Swap the top two items on the stack
&	Copy the top value on the stack
^	Pop the top item on the stack
;	End the program
#	Comment (skips the line)

The program always has to end with ;, otherwise it will cause an exception, this however also terminates the program.
