stjck

This is still a work in progress. It may be changed in the future.

stjck is an esolang created by user:cleverxia. There are no typos here. It has 2 stacks, a IP stack and a data stack

Program flow

every program in queje consist of some commands that does two things: change the IP, and does someting to a stack. Popping an empty stack gives a random number and it's the only way to get anything random. IP out of bounds wraps.

Caption text

command	meaning	what it does
_	advance/APLWSI	IP+=1
@	halt	halt
:	dup	pop stack top(let it be x),push x twice, then let IP=x
`	push	push IP to data stack, then IP+=1
_	discard	set IP to stack top (pops)
[	flag	push current IP to IP stack, then IP+=1
]	branch	set IP to IP stack top (pops)
? (wimpmode only)	condition	set IP to IP stack top (pops) if data stack top!=0 (also pops)
0~9	number	push the number (let it be X), then IP+=X (+1 if X==0)
+	add	pop a, pop b, push a+b, and increase IP by it
-	sub	pop a, pop b, push b-a, and decrease IP by it
*	mul	pop a, pop b, push a*b, and multiply IP by it
/	div	pop a, pop b, push b/a (integer divide, rounds to -inf, x/0=0), and divide IP by it
%	mod	pop a, pop b, push b%a (always positive, x%0=x), and modulo IP by it
<	output	pop a, output a as character, and set IP to it
>	input	input a character, push ASCII code to stack and set IP to it
)	rroll	roll the stack top to the bottom, and set IP to it
>	lroll	roll the stack bottom to the top, and set IP to it
