Hello! Please don't open pull requests on this repo, but rather open them for nori.ni, I really appreciate pull requests!

nori.io

nori.io is a Turing Complete stack-based esolang named after a stray cat I found!

The interpreter reads the program left-to-right, character per character, and always moves right.

Commands

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

Main commands

Command	Description
>	Push the value next to it
<	Pop the last value
N	Push the numeric user input
I	Push the user input
,	Push the user input as an ASCII value
O	Output the last value to the console then pop it
o	Output the last value to the console then pop it w/newline
X	Clear the output
.	Output the last ASCII 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
z	Square root the last value, leaving only the result
%	Modulo last two values together, leaving only the result
c	Ceil the last number
f	Floor the last number
r	Push a random number
b	Push a random bit (either 0 or 1)
B	Push a random byte
[	Jump past the matching ] if last value is 0
]	Jump back to the matching [ if last value is 1
?	If the popped value in non-zero, skip value next to it times
=	Set the IP position to the value next to it (GOTO)
W	Set the IP position to 0 (repeat the program)

nori.io arithmetic is NOS × TOS, meaning that >3>2*, for example, will duplicate 3 (2nd value) by 2 (last value).

Strings

You can define strings using "", for example, >"Hi"O pushes the string Hi and then outputs it.

Comments

You can even define comments in nori.io using the following syntax: ~~ comment ~~

Strings in nori.io are the same as Lua strings, so they might have weird behavior

Varibles

You can define variables in nori.io, |variable|"string" is an example.

|str|"str"
|int|1024
|flt|f5.1
|stk|<      ~~ This sets the variable to the popped value ~~

Example programs

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

Bit inverter

>1@-

Hello world

>"Hello, world!"O

Simple adder

NN+O

Cooler adder

NN@:O>" + "O:O+>" = "OO

Random CJK character generator

Note: might not work on all terminals

r>28607*f>12353+   ~~ generate a code point ~~
::>64/f>64*-       ~~ get the bottom 6 bits ~~
>128+@             ~~ store the last byte ~~
>64/f              ~~ remove the bottom six bits ~~
::>64/f>64*-       ~~ get the bottom 6 bits ~~
>128+@             ~~ store the next byte ~~
>64/f              ~~ remove the bottom six bits ~~
>224+              ~~ store the first byte ~~
...                ~~ print the character ~~
