snø

snø is an esolang I've made for Truttle1's 2023 esojam!

It is a 2D, stack-based esolang of which the IP can only go in diagonal directions

To run main.sn just type python snø.py, if you want to run another file, use python snø.py path/to/file.sn

Commands

The interpreter ignores every other character than these, making them no-op

The IP's (@) default direction is bottom left

Command	Description
`@`	IP starting point
`0`-`F`	Push the corrisponding hex number as an integer
`!`	Pop the last value
`I`	Push user input (1 byte)
`O`	Output the last value to the console then pop it
`}`	Swap the last two values
`$`	Reverse the whole stack
`:`	Duplicate the top value
`+`	Add last two values together, leaving only the result
`-`	Subtract last two values together, leaving only the result
`*`	Multiply last two values together, leaving only the result
`\|`	Divide last two values together, leaving only the result
`^`	Raise last two values together, leaving only the result
`%`	Modulo last two values together, leaving only the result
`~`	NOR bitwise operator (you can make any bitwise operator with this!)
`Y`	If number is non-zero, set direction to bottom left, set to bottom right otherwise
`&`	End program

snø's arithmetic is NOS × TOS, meaning that it will duplicate the 2nd value on the stack by the last value on the stack

Here are some example programs! There are a lot of them (send help they spawn every single nanosecond I breathe)

The IP somehow cannot find the @ so it just gives up

Take the cat program and now put an unicode character such as 🍊, the output will be "ð"
