question: how do you refer to the top of the stack in an if conditional?

say I wanted to check if the top of the stack is equal to 1?

lyxal

you'd need to duplicate it using :

because the if condition will pop the top of the stack

Redz

ohhh

wait so would a code like 4+:100%0=[|,} add four, then check if not divisible by 100, then print if not

lyxal

yes

Redz

this is really cool

lyxal

however, you'd more likely print if divisible

+ you'd use the built-in does this number divide the other element too

Redz

02:13

how would you do two statements at the same time

100%0=400%0!=

or something?

lyxal

depends on what you prefer

there's a few ways

but my choice would be:

(give me a tick to write it)

∥100≛⑵400≛¬∧

Redz

um

lyxal

:100≛$400≛¬∧

Redz

uhh

how does that work

lyxal

the second one is simpler

literally dup, check for divisibility by 100, swap, check for non-divisibility by 400, logical and

Redz

02:16

wait so what is ≛

the weird equal thingy

lyxal

x divides y?

Redz

oh

lyxal

4 mins ago, by lyxal

+ you'd use the built-in does this number divide the other element too

Redz

and ¬ is logical not

lyxal

correct

∥100≛⑵400≛¬∧ is more fun though

it uses modifiers

Redz

02:17

so duplicate, check if divisible by 100, check if not divisible by 400, and both conditions

what does the $ do?

lyxal

swaps the top two values

1 2 $ reorders the stack to have 1 on top

Redz

why is that needed? is it because the first comparison adds to the stack?

lyxal

correct

after :100≛, the result of the check is on the top

if you 400≛¬ without swapping, you're operating on the result of the check

Redz

woah

lyxal

not the number you want to check

Redz

02:19

makes sense

so 400 weird equal sign automatically operates on the top

wait no everything just automatically operates on the top

lyxal

correct

that's how the stack works

things are always popped from the top

@Redz 400 divides? if you prefer literate mode

Redz

code.golf aint literate mode :P

but that makes sense

lyxal

you can convert literate to sbcs on the online interpreter :p

Redz

yeah but that's the easy way

~~ignore the fact school blocks the online interpreter~~

lyxal

oh dang

school never blocked code golf stuff for me :p

Redz

02:23

this is. the coolest language I have ever seen

no school blocks github pages in general weirdly

lyxal

@Redz array languages are like that :p

Redz

can probably get around it with enough time though

lyxal

@Redz I don't think it ever blocked it for me

must be different blocks

Redz

thankfully it doesn't block github in general

hey uh, how do i get the first n of an infinite list?

like i can use i to get one of the items but i don't really see how to get many

lyxal

10:42

@Themoonisacheese would it not just be take?

Themoonisacheese

yeah

i guess adding "first n" or something like that to the list of aliases wouldn't hurt

Themoonisacheese

11:20

well thanks it enabled me to make this codegolf.stackexchange.com/a/278381/88192

Themoonisacheese

what's the recursion limit?

because Vyxal 3, 30 bytes: #[4#]λ1|:e#⍰2∻⑵3×›¥›£1≠#⍰x¥}M Vyxal It Online!fails with n>3 and that's quite low imo

(it's also like, wrong, so maybe it's recursing much more than i think)

lyxal

@Themoonisacheese 100

Themoonisacheese

i mean that's low but i shouldn't be hitting it

lyxal

github.com/Vyxal/Vyxal/blob/…

Themoonisacheese

also the error isn't the standard "too much recursion" error, it's actually the scala too much recursion error

lyxal

wish it'd say what was recursing too much :p

@Ginger I am doing online dating. Man, there are a lot of weirdos out there. I'm proud to be one of them.

Ginger

based

Bridget

@lyxal [RubenVerg] hey they invented debuggers for a reason

lyxal

Doesn't mean the error has to not specify which scala thing is being called too many times

:p

Ginger

guess I don't have to do unified versions anymore since there aren't going to be any more versions :3c

but I feel like theseus still has potential... alternative RTO frontend, maybe? :p

Themoonisacheese

13:48

@Ginger yeah i thought about that yesterday

guess you're now compatible with all future versions

Themoonisacheese

14:16

i give up on implementing collatz stopping time

i understand why i hit the recursion limit (next 2 as lambda is a bad idea if one of the 2 is recurse) but even a thing that should be strightforwards fights me

my minimal example is Vyxal 3, 17 bytes: :1#{≠|:e#⍰½⑵3×›x} Vyxal It Online!

and i cannot for the life of me understand why it's stopping at 31 of all places

shouldn't all results be 1?

Weird Glyphs

15:48

The best solution I'm able to find currently is 21: 0${:1>|$›$:e#⍰½⑵3×›}$ Vyxal It Online!

@Themoonisacheese I will try to see if your code can be fixed

Themoonisacheese

@WeirdGlyphs fyi $[element]$ is always equivalent to ⎇[element]

i guess that works but i was trying to avoid putting something else on the stack and use registers

Weird Glyphs

@Themoonisacheese Nice then :) Still discovering how all of this works, so it's possible for me to miss obvious solutions

Themoonisacheese

no worries that's how you learn

good news the languages spec is now stable :D

Weird Glyphs

I can at least replace 1> with decrementing the value

Themoonisacheese

16:05

tbh you're better at this than i am

@lyxal worst part is that i had used it literally yesterday on code.golf

Weird Glyphs

16:18

The only problem with your previous code seems to be the #⍰ condition. If you use an elif statement, it works, but it doesn't otherwise, idk why

Bridget

17:40

[Themoonisacheese] that's so weird though, you use the same thing
