@mathcat how many bytes do you have for the latest challenge?

→ 1 sausage moved to The Nineteenth Bakery

mathcat

the canvas element one?

lyxal

No, the 69420 one

mathcat

Oh, I thought you meant my latest challenge

lyxal

No lol I mean the latest from the NP bot lol

mathcat

I didn't manage to do it

hey what the hell happened here

lyxal

There was a conversation on digital piracy

And it was moved to that room because it was off topic for here

Unrelated String

it was simply too based

Ginger

oh

emanresu A

@lyxal You realise infinite lists are allowed, right?

Ginger

yup, piracy is a totally normal thing to be discussing in a room for Crogramming Guzzles and Sode Eolf

lyxal

11:05

@emanresuA how about an infinite list of lists?

Ginger

feedback please!

Nobody Needs Names

o/ chinese class coming but actually i'll look at @Ginger 's stuff

emanresu A

@lyxal Nah, flattening is necessary

lyxal

Can't blame me for trying to remove the ;f lol

Ginger

I forgot I had my speakers turned up to test my ping sound and OH GOD LYXAL'S FRIDGE HAS BROKEN MY EARDRUMS

lyxal

11:08

It does that sometimes

Nobody Needs Names

As i said, maybe, for each rule, make it a bullet point and under it give an example of violation

and explain

o/

lyxal

@Ginger Why else do you think it gets nuked so often?

Ginger

oh

anything to say about my challenge?

mathcat

Why do you have plastic cups

why not glass cups

Ginger

Why do you not have plastic cups

mathcat

11:10

good point

Ginger

haha gotchu there

lyxal

@Ginger have a gray cup to match the plate colour scheme I have

I have blue, green, pink and gray plate

No yellow

I'm addicted to CGCC no...

mathcat

11:20

Addiction is only when you want to consume more and more of it daily.

I'd just say CGCC is a habit of mine.

Nobody Needs Names

@mathcat That's me, cuz I'm back again

mathcat

oh well

Nobody Needs Names

Ginger

@lyxal I meant more about the challenge

Nobody Needs Names

@lyxal oh no, yellow is my favorite color

emanresu A

11:33

lyxal's is #beedab

Ginger

my favorite is of course #01abda

hey you know what I don't like? the fact that the enable desktop notification text only has a 2 pixel margin

also:

who's this "lyaxl" guy?

Nobody Needs Names

idk

mathcat

lyxal's dark twin

Nobody Needs Names

#c0ffee actually looks good

#05ab1e is too green

I like #f0f000

but #f0000d is good when you are hungry

i have inspiration for a new challenge

CMC: given a dictionary of words output all 3 letter or 6 letter words that only include letters in "abcdefolsg"

and change all o to 0 and l to 1 and s to 5 and g to 9

and i to 1 too, i can be too

both #bad and #badbad seems good

lyaxl

@Ginger I dunno

I dunno who lyaxl could be

seems like a gamer

@graffe hour hand rotates at 0.5 deg/min minute hand at 5 deg/min i.e. 12 times faster. now imagine a second clock with its hour hand where the first clock's minute hand is, then the second clock's minute hand will be 144 times the angle of the first clock's hour hand. but we want that to be the same angle modulo 360 deg, so 143 times the angle is an exact multiple of 360 deg i.e. 12 hours, so as they are coprime there are 143 such times in a 12 hour period.

Nobody Needs Names

@lyaxl you used my method

lyxal

Nah, it's just what I already had on Arqade lol

and using site changes for different usernames isn't anything new either lol

emanresu A

Nobody Needs Names

oh ok

good

How do I delete one character of output in Python3?

For instance, I just ran

```python
print("Hello, World!")
```

But I want my STDOUT to say:

```
Hello, World
```
.

I will not accept answers that prints many newlines, but I will accept answers that clear the screen instead.

I am OK with modules, but I don't particularly flavor them.

Ginger

12:09

one second

Nobody Needs Names

ok

one second is up

jk

Ginger

Assuming the cursor is at the end of the line you want to erase, simply use: print("\x1b[1D\x1b[K")

final chance for feedback before I post!

Nobody Needs Names

@Ginger is there a reason you are not taking my advice?

for each rule, make it a bullet point and under it give an example of violation and an explanation @Ginger for your feedback

Ginger

12:24

It'd be too much trouble to implement

and also unnecessary for this challenge

Nobody Needs Names

ok then, tbh i dont understand it, but idc

Nobody Needs Names

12:35

@Ginger how is it unnecceesssssary i suc at speelingggggg

thejonymyster

12:50

unnecessary is a tough one

i find its a bit easier if you split it into un + necessary

also "definitely" = (define => definite => definitely)

Nobody Needs Names

technically i suck at typing it and i'm just a bit lazy to retype it

thejonymyster

woah, does python 2 not have ++

Nobody Needs Names

and unnecessary is hard to type wrong

@thejonymyster sorry, but python3 doesn't have it either

thejonymyster

wtf why lol

~~its so golfy they should add it~~

Nobody Needs Names

hmm

how often do you need ++?

Ginger

12:57

here's a trequel program using the function-definition syntax I jut came up with:

DEFINE SAYHI WITH NAME
	SHOW "Hello, " + NAME
DONE
NAME IS INPUT WHERE PROMPT IS "What's your name? "
CALL SAYHI WHERE NAME IS NAME

thejonymyster

can you CALL SAYHI WHERE NAME IS INPUT WHERE PROMPT IS "What's your name? "

Ginger

yes

thejonymyster

:D

Nobody Needs Names

@thejonymyster how often do you need ++?

and r u learning python?

Ginger

wait, that syntax is actuallt wrong

thejonymyster

13:00

@NobodyNeedsNames so much it is like my lifeblood

no uh :P

Ginger

it should be CALL SAYHI WITH NAME AS NAME

but tbh that's stupid and inconsistent

thejonymyster

@NobodyNeedsNames i was just looking at a python answer that had i+=1

Nobody Needs Names

@thejonymyster example

@thejonymyster which

thejonymyster

@NobodyNeedsNames i use js so... every loop :P

Nobody Needs Names

in python

...

b/c js has ++

thejonymyster

13:01

i dont use python :P

Nobody Needs Names

plus, ++i++ is so confusing

o/ gotta go

thejonymyster

@NobodyNeedsNames this :3

peace o/

also i do agree the ++i vs i++ thing confused the hell out of me

i google every tiem

what are those symbols?

Ginger

13:15

?

Nobody Needs Names

???

thejonymyster

%15? "? +1? 100? Those aren't letters are they? :P

Ginger

sorry what

thejonymyster

why have % when you can have MODULO

Ginger

I'm not that evil

Nobody Needs Names

13:16

you can do

thejonymyster

can i at least see what im doing if i use indents? :]

Nobody Needs Names

you can do this

txtpad.cn/ddddddd

too long to put in chat

Ginger

jesus shit I said evil not insane

thejonymyster

@Ginger how come its IF X DO SHOW but ELSEIF Y SHOW

where does the DO go

or does it need to be there at all

Nobody Needs Names

wait where's the buzz?

thejonymyster

13:22

probably one of those "FizzBuzz"es is meant to be a "Buzz"

Nobody Needs Names

yeah...

Ginger

oh whoops

DO IF NOT N%15 DO SHOW"FizzBuzz"ELSEIF NOT N%3 DO SHOW"Fizz"ELSEIF NOT N%5 DO SHOW"Buzz"ELSE SHOW N DONE FOR N IN DO N+1 TO EACH N OF RANGE WHERE END IS 100 DONE DONE

there fixed it

Nobody Needs Names

can you make it all letteers no space all upper?

thejonymyster

probably needs some spaces

... maybe

i think it might get confused by NOTN

Ginger

spaces are needed

thejonymyster

13:26

for sure

Nobody Needs Names

use

say

SPACE

Any thoughts on this layout?

@mathcat what are you trying to make

@mathcat The rightmost button clips off of my screen

mathcat

@PyGamer0 An interactive evolution program

PyGamer0

@Ginger lol i noticed that too

@mathcat nice

mathcat

@RadvylfPrograms the "start evolution" button?

Radvylf Programs

Yeah, and with dev tools open, all of the right panel is offscreen

Seggan

15:22

@mathcat whats that

nvm

mathcat

@RadvylfPrograms uff okay

Radvylf Programs

@mathcat Ooh I love making stuff like that

mathcat

I'll have to shrink the canvas then

Radvylf Programs

I think the canvas isn't the problem

It's the layout itself, you need to use flex or grid or something to dynamically resize things

Otherwise you're just kicking the can down the canvas

Ginger

yes, use flex

use flex for everything

mathcat

15:23

I'll flex

Ginger

my motto is "never stop flexing"

is there a challenge about maximizing the size of an error message

cause i found something pretty great

Ginger

why is my editor being possesed by demons

mathcat

@RadvylfPrograms can you send a screenshot?

DLosc

16:23

@thejonymyster I definitely remember a challenge like that... trying to find it

thejonymyster

@DLosc i know theres "output an error larger than source" but im thinking more like "largest number printable" but for errors instead of numbers :P

but please do tell me whatever you find :D

DLosc

Hmm. There's this, which was closed as a dupe of Largest Number Printable.

thejonymyster

aw what why is that a dupe lol

DLosc

I now suspect I may have been conflating that with Slow Error Quine Maker, which is about feeding the error output back into the interpreter and trying to get the longest chain before it repeats.

thejonymyster

drat

i probably was remembering that too

i found this fun js program: f=_=>eval(f=${f};f());f() dont run it in browser console or whatever

try it here

idk if this behavior is specific to this interpreter but its pretty great

havent tried on, say, tio yet

but an interpreter is an interpreter ~~you cant say its only a half~~ meaning it would count :P

Neil

16:42

hmm, someone doesn't like most of the answers to codegolf.stackexchange.com/q/248207 for some reason

pxeger

there is an exact correlation between answers which are downvoted and answers which acknowledge copying from the OEIS

Radvylf Programs

Without dev tools

With dev tools

@mathcat Done

mathcat

Of frick

I forgot people use monitors

Radvylf Programs

That's my laptop screen

mathcat

what

Radvylf Programs

16:51

3:2 gang ftw

mathcat

This is how it looks on my laptop

Radvylf Programs

Even for 16:9, lots of laptops nowadays are 1080p, so assuming 1366×768 isn't really a good idea

mathcat

ah okay

pxeger

assuming any fixed resolution or aspect ratio really isn't a good idea

Radvylf Programs

Yeah, but it's reasonable to assume something between 4:3 and 2:1 IMO, designing for things like square screens and mobile is way too annoying for a project where the focus is not on the UI

smarnav

17:39

question idea: baudot ascii art. I have looked a bit, and it doesn't seem to duplicate anything. I don't feel like writing a sandbox, as it takes a bit of time to write a decent post, and I can't get immediate feedback. my idea is: write a program or function that converts it's input into an ascii art punch tape like this: pastebin.com/raw/SnGBbnwX what do you think?

I do, and will in the future, but now I just need a bit of quick feedback. I try to put my best foot forward, but I don't have nearly enough time right now to sandbox it..

Ginger

yea I didn't fully read what you said

sorry

what drugs is replit on

Neil

18:43

@pxeger although strangely one of the non-downvoted answers acknowledges copying from an answer that acknowledges copying from OEIS

Radvylf Programs

Downvoting answers that port code from OEIS seems kinda silly

I'd guess at least a third of answers to new questions are ports, I don't think there's really anything wrong with that, and downvoting ones that "admit" to it is just punishing people for being transparent

Like, not everyone's going to invent their own way to solve a challenge, and there's still work to be done in changing the syntax and looking for golfs in the ported-to language.

smarnav

online encyclopedia of integer sequences?

Radvylf Programs

And one feature of CGCC is that answers are almost like a catalog of solutions in different languages, so while trivial ports maybe don't deserve upvotes, downvoting them discourages one useful aspect of our site from existing

pxeger

@smarnav yes

hyper-neutrino

there's already a sentiment that once someone's solved a challenge in an answer or in a certain byte count it gatekeeps the competition (like people saying it's too hard to get in a python answer because of good python golfers when we welcome someone submitting a worse scoring answer afterwards)

I think it would be extremely harmful to also set the sentiment that once someone's come up with a particular idea nobody else is allowed to anymore - especially with many challenges where either there's only one possible approach that isn't extremely convoluted/roundabout, or all other approaches aren't possibly as competitive

smarnav

19:08

where are the standard code golf runes for answers?

Seggan

?

smarnav

ᛟᛟᚹᛇ :P

I meant rules, but now that I think about it, a rune coding language would be interesting

Seggan

what do you mean by "code golf rules"

i.e. standard loopholes and i/o defaults?

smarnav

yes

I remember them being on some meta post...

Seggan

loopholes

i/o defaults

pxeger

19:16

a list of the most common things you'll want to know can be found at faq

and a comprehensive list of all the rules (including partially incorrect ones, annoyingly) should be constructible by looking at policy

OTL i posted a weird challenge idea i had (into the sandbox) but it was way too detailed and strange so i simplified it until it became something more manageable but then i looked at it and it had just become "count permutations"

emanresu A

@DLosc Looks like Pip's the LYAL?

DLosc

@emanresuA I'm planning on it :)

Trying to boil the language down into a crash course for chat, I've realized just how much there is to it. My other languages tend to be fairly simple (either by design or because I lose interest before they're fully fleshed out).

Seggan

...

i just realized Pip's not Pyth

DLosc

Or, rather:

Pip
Isn't
Pyth

They certainly have some superficial similarities: Python-based ASCII golfing languages that use an imperative paradigm.

thejonymyster

derivative lang named pnp (pnp's not pip)

DLosc

21:45

PNP was the original name I thought of (PNP's Not Python/Perl/PHP), before I realized I could tweak it to PIP and that would be pronounceable.

Radvylf Programs

If anyone makes a language called PNP I call the rights to NPN

It would be doped

Get it

Seggan

Then I call rights to TRANSISTOR

DLosc

22:03

CMC: Given a 2D array (or equivalent) of integers, return an array with the same dimensions that contains a single 1 in the upper left corner and 0s everywhere else.

thejonymyster

thats oddly specific, did you find this solution by accident :P

DLosc

I'm golfing this. I think that transformation might be helpful, but I'm having trouble thinking of a simple way to do it in BQN.

thejonymyster

ah i see, interesting

DLosc

Found a 7-byte solution in Pip, incidentally

Radvylf Programs

@DLosc rSN: x~(n=1;x$y~y$z~n=0

thejonymyster

22:13

the 1 in the corner really is what makes this tricky to do golfily

@DLosc js, a shameful 45 bytes x=>{x=x.map(w=>w.fill(0));x[0][0]=1;return x}

unless theres some way to grab the transformed value of x after x.map(w=>w.fill(0))[0][0]=1 im stumped

emanresu A

@thejonymyster return x is unnecessary

as you're modifying x by reference

thejonymyster

oh, i didnt know that worked like that in this context

sweet -9 :]

Wezl 'l o - o l'

x=>(x=x.map(w=>w.fill(0)),x[0][0]=1,x) also works btw

thejonymyster

oh interesting

Wezl 'l o - o l'

x=>((x=x.map(w=>w.fill(0)))[0][0]=1,x) too

thejonymyster

22:26

does it?

that seems like itd set x to 1

weird

how does htat evaluate?

oh i just caught the

extra parenthesis... ahaa

emanresu A

@Wezl'lo-ol' Again, returning x is unnecessary

thejonymyster

putting you at 34, nice golf

Wezl 'l o - o l'

true but I like returning x :P

emanresu A

Vyxal, 5 bytes

thejonymyster

g=x=>x.map((w,i)=>w.map((a,b)=>!i&&!b)) with true for 1 and false for 0 :P

if only js had builtins for all the gates

ignore my weird var choices

emanresu A

22:33

(fill by (multidimensional) coordinates -> all false)

thejonymyster

lol thats basically what i was doing :P

(kind of?)

emanresu A

Vyxal has better builtins ;)

des54321

been fiddling with this in python and i think the best python can do is 52 bytes: def f(a):x=[[0]*len(a)]*len(a[0]);x[0][0]=1;return x

att

apl 8 ⍴⍴1↑⍨≢∘,

@des54321 44: lambda m,i=2:[[i:=i//2for _ in r]for r in m]

des54321

hot damn i cant believe that works

Wezl 'l o - o l'

22:46

jq, map(map(0))|.[0][0]=1

att

@att wait it can be just 4 1↑⍨⍴

emanresu A

What does that do?

att

take (shape of input) elements from 1, filling with 0s

Radvylf Programs

Ooh a bunch of HTTP-related RFCs just got released, like 9110 (HTTP stuff), 9112-9114 which are for HTTP/1.1, /2, and /3

att

the 8byter flattened to do ↑ in 1d before reshaping but it also works with >1 dimension

emanresu A

22:57

@DLosc CMC: this with arbitrary dimensions

Wezl 'l o - o l'

the apl one already works IIUC

att

yeah it should

Wezl 'l o - o l'

sed, IO in (one-line) JSON, s/[0-9]/0/g;s/0/1/

att

@DLosc looks like the apl maps pretty easily to bqn 1↑˜≢

thejonymyster

23:17

@emanresuA something something eval, regex replace, string repeat...

user

@DLosc Scala 3: _.zipWithIndex.map{(r,i)=>r.indices.map{j=>1-1.min(i*j)}}

making a builtin that switches a character to its "alternate". i have lowercase<=>uppercase, open bracket <=> close bracket,
