So i have a list of numbers in jelly. how would i convert it to a string?

lyxal

00:19

do you mean turn it into a single number?

Try it online!

does anybody here have experience with adding a language to code.golf?

Bubbler

Maybe you can ask directly to code.golf discord or open an issue on the official github repo

Seggan

@lyxal no as in [83, 115] = "Ss"

lyxal

@Seggan then I'd suggest you take a look at the monadic atoms list

Bubbler

@Seggan It's Ọ (chr; cast as character)

lyxal

Or that

Seggan

00:51

yeah, just figured it out myself "Ọ€"

lyxal

No need for the €

Bubbler

All functions that act to a single number auto-map or "vectorize" to entire array

Seggan

ah, ty. useful

Q: Fibonacci-like gap formula

Background The recurrence of the Fibonacci sequence is defined as $$ f(n+2) = f(n+1) + f(n) $$ From this recurrence alone, the following gap formulae (recurrences relating three terms with certain amount of gaps) can be derived: $$ f(n+4) = 3f(n+2) - f(n) \\ f(n+6) = 4f(n+3) + f(n) \\ f(n+8) = 7f...

@Bubbler is this a valid answer for your Fibonacci-like gap formula question?

Bubbler

05:05

@PyGamer0 Yes

PyGamer0

@Bubbler oh i was confused about the floating point error 7.00000000001 thing

Bubbler

FP error is generally acceptable

PyGamer0

ok

@hyper-neutrino you seem to have misspelt "Zsh is currently the second-top voted language for November's LotM - make sure to place your votes in time for next month to make sure it wins"

hyper-neutrino

well we now have a three-way tie

pxeger

but Add++ is the earliest, and Zsh is the second-earliest

Bubbler

I feel the need for more LotM nominations (there are like 20 languages on Codewars and 10 on code.golf that are barely used on CGCC and haven't yet been an LotM already)

pxeger

I'm gonna nominate Ruby

I like Ruby

Bubbler

but I don't feel like I'm the right one to write for any of them, mainly because I haven't tried seriously learning those

I could write some for Martin Ender's langs actually

labyrinth?

Bubbler

Labyrinth, Hexagony, Alice, Wumpus, Stack Cats

Maybe not Retina

Razetime

hexagony looks good tbh

there's an amazing editor for it

Bubbler

I have used four of them before

and yeah, hexagony IDE is crazy

Razetime

@pxeger ruby is too highly used afaik

pxeger

not many people use it regularly on this site

Razetime

06:50

me, dingus, level river st i think?

i've been lacking in answers lately :/

lyxal

@pxeger you seem to have misspelled "Zsh is currently the top voted language for November's LotM - make sure to place your votes in time for next month to make sure it wins"

pxeger

lol you didn't have to do that

Bubbler

Honestly "there are fewer than 10 PPCG users who regularly golf in this language" should be somewhat adjusted. Practically every lang meets this (we don't even have 10 regular users of Jelly or 05AB1E)

pxeger

oh 2 upvotes

I wasn't expecting for Zsh to end up as LotM so I need to prepare now lol

Razetime

there are 3 days left so let's not "curb your enthusiasm" ourselves

lyxal

06:54

@pxeger yes I did. I had to make the obvious joke

Razetime

@Bubbler even in the heyday this may not have been accurate

lyxal

It's probably to avoid having langs like python or js as lotm

Razetime

hm fair

@RedwolfProgrammed do you have a script to hide deleted answers

Bubbler

Suggested rule of thumb: "you seriously like the lang, you have seriously used it several times on CGCC, and you seriously think it is underused"

or has it been already done?

There's already a proposal for desmos

i like desmos, hope it turns up soon

07:36

@Razetime yes i joined reddit just for r/desmos :P

CMP: pygame or pyglet?

lyxal

pygame

emanresu A

PyGamer0

pyglet

much easier

lyxal

@PyGamer0 reddit username?

Bubbler

@PyGamer0 What do you want to do with either of them?

PyGamer0

07:45

@lyxal hint: same name

@Bubbler make games / simulations

Bubbler

Then arguably pygame

PyGamer0

@Bubbler and opengl dont forget opengl

Bubbler

because it makes easier to handle everything you'll need in making a game (graphics, sound, mouse/keyboard,...)

PyGamer0

@Bubbler i think pyglet is way easier for me

Bubbler

Then you have your choice :shrug:

lyxal

08:02

@PyGamer0 then your account must be too new to find

Ngl github copilot is more passive agressive then I thought it'd be

I was trying to get it to complete a for loop, and it just suggested the start of a comment

like this:

for var in whatever:
    #

very helpful

so I wrote

for var in whatever:
    # yes thank you for suggesting a comment start very cool

or something like that I don't remember exactly what

anyhow, it eventually got to the point where it suggested going to stackoverflow.com/questions/1265665/…

but there's just one problem with that

just one tiny little problem

pxeger

that question is not about converting to binary lol

lyxal

yeah exactly

so I wrote a comment saying "that's not even the right title idiot"

and it spammed that one link like 10 or 15 times

and that's my experience with the passive-aggressiveness of github copilot

Aaroneous Miller

i like that one

fortunately, changing that in the implementation is as simple as changing a single / to ,

that totally isn't what ><> uses and that totally wasn't subliminal inspiration for my suggestion

of course not

I could never even imagine something like that being the case

no

it's been 10 minutes now

Aaroneous Miller

12:38

shut up

lyxal

it can't take that long

hurry up and write it so I can upvote it and go sleep

Aaroneous Miller

i think its just about done, i just have to get the infinite loop going

lyxal

then it isn't just about done is it. it's only 50% done

the infinite loop is like half the fricking challenge

50% != almost aaron.

smh

Aaroneous Miller

but it's about 5-10% of the program

lyxal

that doesn't matter aaron it's 50% of the challenge which is more weighting than your "5-10%"

Aaroneous Miller

12:43

i suppose so

lyxal

did you not learn how percentages work at code golf school?

Aaroneous Miller

naw, college is wack

lyxal

ah ofc ofc

@Razetime I do, but only for the sandbox

I don't remember if I still have a copy, A username should though

thejonymyster

is a username the same person as emanresu a

Redwolf Programmed

Yeah, they reversed their username at one point for some reason

thejonymyster

alucard

Redwolf Programmed

And because they made a challenge about their reversed username, it's stuck (according to them)

thejonymyster

username challenge thought: if you make a challenge relating to having your program print a username, and allow the player to take the length of their username off their score, and their lang of choice and username just to happen to allow it, they could technically get a negative score

like say if someones username is just a bunch of 1s lol

Redwolf Programmed

13:28

Negative byte counts arem't too uncommon in challenges that allowed bonii

(The plural of bonus)

thejonymyster

oh, yay :]

pxeger

@thejonymyster or if you're Lyxal and you just include your username in your language's compression dictionary

thejonymyster

ofc lmao

thats the expletive version of ofc btw

Redwolf Programmed

Ash's dictionary actually had lots of usernames since I used CGCC's challenges as a corpus, and the usernames were included

thejonymyster

oh thats funny

imagining someones username just happens to have some useful properties

thatd be funny to come up in a challenge
