No, only ⍎ and ⍕ and ⌶ can natively execute code.

@Adám How to transpile APL code with ⎕R to QR

@taRadvylfsriksushilani Is there a way to inspire commands for golfing languages?

Yes, you give them a little pep talk first

@Adám Can even ⍨ do it?

@Fmbalbuena Each regex of the left operand becomes a line of code, and each regex of the right operand becomes a a line of code. If the right operand is a function, write it as a dfn body (without braces) and use ⍵X where X is the initial of the member, e.g. ⍵.Match becomes ⍵M

@pxeger I mean, all you need is (⍎⍨∘#), right?

Or something like that

9:07 PM

@Adám then ⎕←'Hello, World!'⋄⋄ prints Hello, world!, right?

@pxeger Try it online!

@Fmbalbuena Try it online!

@Adám how this works?

transpiled APL code?

@Fmbalbuena Try it online!

ok

A: What is our consensus for fractional byte functions?

Fractional byte counts are always allowed It seems like one very simple solution to this problem is to allow fractional byte counts, for functions and full programs. WW's answer implies that some sort of custom designed file system would need to be written, after which point this would be the cas...

(Couldn't write this up until now because mobile)

@Fmbalbuena Well, I'd start by going through a few languages you like, and keeping any built-ins from those that seem useful. After that, you can start writing pseudocode with those operators, and see if there's anything you feel like you're missing.

E.g., if you keep using two built-ins together, it might be a good idea to add a build-in that does both of those in one byte. If you try to do something simple and it takes way too many bytes, think of some good general purpose built-ins that would make that task simpler.

Time to write FractionOS

ta Radvylf srik su shilani

Well, the point of my proposal is that we don't need the weird file system simulator :p

Doesn't mean we shouldn't make one for the memes

ta Radvylf srik su shilani

I've always wanted to make an OS

There is copy.sh/v86

9:51 PM

Hang on, my family's calling my cat rude names

Turn them into cats

ta Radvylf srik su shilani

@emanresuA Ooh I love that, I used to mess around with it and do stuff like rm -rf /var

My computer uses NTFS. I doubt you really want me to change most of my complete program scores to 1024 bytes (the size of a NTFS base record). — Nitrodon Jan 6 at 19:19

@taRadvylfsriksushilani The nice thing is, your cat probably doesn't understand what your family is calling it, just like your family doesn't understand the rude names your cat calls them.

A while ago, I posted this mostly as a meme, but it ended up being kinda fun. It'd be interesting to see how fast other golflangs could get.

ta Radvylf srik su shilani

10:01 PM

Feels nice not having any pins

I'm so used to skipping the first like, two messages lol

Kinda sad how we have 13 new users who've actually done something (+2 who suggested an edit).

@mathcat I can't remember the last time I've seen someone talk with their hands that much X^D

@emanresuA It's actually more: there 24 others who don't have an association bonus (currently on page 6).

And that's assuming that everyone with 101 rep has the association bonus rather than having received exactly 10 upvotes.

Oh true, didn't see/think of that

10:22 PM

@emanresuA I'm afraid to try it :P

Pip's probably faster than Vyxal

No prime builtins, though

Oh. Idk then

Output buffering is still the hard part

I guess I could port Neil's answer--it looks reasonably understandable.

Vyxal is very different from the rest in that it has completely optimised prime builtins but is very slow in general as everything gets pushed to a stack

10:36 PM

Pushing to a stack shouldn't make it that inefficient, honestly

For math stuff, sympy does most of the heavy lifting

I just realised, my one would be twice as fast if ∆Ṗ skipped even numbers

Actually maybe not twice as fast but still faster

...why don't we skip even numbers? ಠ_ಠ

And why isn't sympy skipping even numbers?

Because ∆Ṗ is next prime

Oh ok

Oh I mean in 2.4.1

In 2.6 sympy does it

10:40 PM

@taRadvylfsriksushilani give me some examples

ta Radvylf srik su shilani

Of languages to take from?

Jelly, APL, Vyxal, Husk, Python, etc.

No, challenges

   factor = 1
    while not is_prime(item + factor):
        factor += 1

@emanresuA item?

is item argument?

yes

10:41 PM

then i will recreate

(I have to put Prime checking, i will put to my lang)

It's Vyxal 2.4.1's source code for the next prime builtin, and it doesn't skip even numbers

@Fmbalbuena What are you writing it in?

@emanresuA tacit

I think what emanresu meant is what programming language you're writing it in

@user Python

@emanresuA Python 3

@emanresuA Ok, another challenge

Use sympy's prime stuff then

I'd highly recommend using sympy's rationals as well, it makes type handling a lot simpler.

10:49 PM

@emanresuA sympy?

@emanresuA I don't know how much of this slowdown is due to testing on Replit, but on Replit my (not terribly optimized) first attempt took almost 6 seconds to do primes up to 1000. And it didn't print them, just looped over them. :P

@Fmbalbuena sympy

@emanresuA I don't like Import

@emanresuA Check if the number is prime in sympy?

sympy.isprime(...)

py -m pip install sympy

10:53 PM

There are docs, use those

@emanresuA i don't see any.

Sorry, actually mantained docs

Weird, I'm trying to redirect my output to a file so I can measure how much there is, and the file is blank afterwards.

Is your output to stderr or something?

I don't think so, because it doesn't show up in the console either when I have the redirection in there. Something weird with timeout, maybe? Let me try it without timeout.

11:02 PM

←F1
⌹F|←F@-+1∇

@emanresuA ^ (I will choose which char does the loop and variables later)

I don't understand APL

@DLosc Are you taking implicit input? (I was having the same problem and that was why but idk if pip does that)

@emanresuA pseudocode, I will implement later.

= F 1
F + ARG, F PRIME NOT LOOP

@emanresuA Not quite sure what you mean--I am using a command-line argument at the moment

But it's definitely timeout.

When it doesn't hit the timeout, all is well; when it does hit the timeout, there's no output to the file (even though it outputs to stdout as normal if I don't do a redirect).

@DLosc Vyxal online takes implicit input and zeroes if there's no input, but Vyxal offline prompts for input

I would copy the command from the OP, but Replit doesn't have pv installed apparently

@emanresuA Oh, okay. Yeah, nothing like that.

11:07 PM

@emanresuA Which i'm missing? another challenge?

What do you mean?

@emanresuA which commands i need?

@DLosc I just went gtimeout 1m Vyxal.py file > e

@emanresuA Trying that... aaaand Replit doesn't have gtimeout either. I'll try on a Linux VM later.

timeout should also work, I just used gtimeout 'cos macos

11:10 PM

It's possible it has something to do with how timeout halts the program. I'm not sure if Pip always responds "nicely" to being force-halted.

(Although, again, it looks fine when I don't have a redirect... hmm)

Maybe I can try tee

Same result--no output to stdout or the file.

I'm almost wondering if it's something weird with Replit...

> ./pip.py primes.pip 100 | wc
     26      26      77
> timeout 1s ./pip.py primes.pip 100 | wc
     26      26      77
> timeout 1s ./pip.py primes.pip 1000 | wc
Terminated

If you'd like I can try with gtimeout?

If you want to, but I can try it on a Linux VM in a bit. Replit isn't the best place to run timing tests anyway, I'm sure.

Like TIO, it's not consistent enough

@emanresuA A trash challenge for my golflang?

Wdym?

11:20 PM

Huh--somebody just upvoted seven of my questions in rapid succession. Wonder if it'll get reverted. :P

@emanresuA You gave me a challenge

@DLosc gotta get that strategic vote cap

Because I gotta overtake gnat on the voting leaderboard

@lyxal ... That is a user with very surprising statistics.

11:27 PM

@cairdcoinheringaahing Their CGCC account isn't even tied to their other accounts (in which case, something's weird because how does they have an association bonus?)

caird coinheringaahing

@DLosc Hidden communities

:o

@DLosc by my calculations, I won't actually achieve the overtake until next year - if I consistently hit 40-vote vote caps this year, I estimate I'll be within a few thousand votes by year's end

Q: How do I hide my accounts on a specific Stack Exchange site?

Can I hide my accounts that I already participate in, for a specific site? For example, I'm in one where I don't want to make my accounts visible for others: Or is this not possible?

support hidden-communities

@lyxal I can subscribe to your channel?

11:30 PM

@lyxal You haven't this year, you have 677/720 votes. You'll probably be able to quite easily get electorate afterwards

caird coinheringaahing

@Fmbalbuena Only 21% of viewers subscribe to lyxal's channel, so if you like this video, please go ahead and subscribe, it'd really help lyxal out

@cairdcoinheringaahing done

@emanresuA a few close votes should help fix that, and the maximum would be 680 because vote cap hasn't reset yet

Also, answers being deleted probably subtract from my total

@cairdcoinheringaahing That's the second new thing about StackExchange I've learned here today. 2TIL.

@emanresuA Because I know I've vote capped every day this year

11:34 PM

@lyxal Oh

Oops I miscounted

caird coinheringaahing

@DLosc What was the first?

6 hours ago, by pxeger

you can also press Ctrl+K, which doesn't require you to have entered multiple lines

(for fixed font in chat)

... Which suddenly makes me wonder why the fixed font button isn't available unless you enter multiple lines, since fixed font is possible with one line. Hrm.

spaghetti code ¯\_(ツ)_/¯

caird coinheringaahing

@DLosc Because backticks exist for "fixed font" on single lines

@lyxal Oh, do close votes count as well?

Unrelated String

11:38 PM

so I guess it's to encourage not using the block formatting for single lines?

(In that case, I'd recommend using some delete votes)

@UnrelatedString Unless you're on mobile, then you kinda have to

caird coinheringaahing

You can't include replies (in the :<message-id> format) in fixed-font, but you can with backticks

@UnrelatedString Hmm, I guess it does take up more space.

@lyxal commented your video

backticks are also really cursed when you're trying to put backslashes or backticks in things but I suppose that's relatively niche

11:39 PM

As with language design, it's corner cases all the way down :P

Unrelated String

@emanresuA in what way

At least, I can't type backticks on mobile

Unrelated String

(typed on my iphone btw)

caird coinheringaahing

@emanresuA wait, really?

Unrelated String

typing three backticks is a pain in the ass on ios but single backticks are fine

don't know about android keyboards but i highly doubt it's impossible

caird coinheringaahing

11:40 PM

If you'er on iphone, press-hold on '

Oh

@emanresuA I think so

i actually have one of those replacement suggestion things set up for triple backticks

Thank you razetime

Very cool.

Yhat reminds me I have a draft typed up on mobile

caird coinheringaahing

@lyxal Fricking savage

@UnrelatedString prnt.sc/26ex3iq it's right there on the second page of symbols

caird coinheringaahing

@hyper-neutrino ...you have suit symbols available on your English keyboard?

apparently :P

Any feedback on BCD to binary, with bitwise?

caird coinheringaahing

11:46 PM

@lyxal Ask that on WindowsPhone.SE

ta Radvylf srik su shilani

@lyxal Ask on Windows Phone SE :p

What a ninja D:

caird coinheringaahing

I'm just that good :D

@lyxal Yes, but not SE because ES2020

ta Radvylf srik su shilani

Wait, SE uses ES2020 stuff?

Seems like they'd have more compatibility in mind

They upgraded their javascript recently

Idk why

What's the cutoff date for nominations to best of CGCC?

ta Radvylf srik su shilani

11:47 PM

They might do what YT and other sites do, and send different JS depending on user agent

Is it before the nominations started or in 2021?

ta Radvylf srik su shilani

In 2021

I've placed it on its charger so I'll check in to see if I can use chat on Windows phone a bit later

caird coinheringaahing

@emanresuA As in, for posts to nominate for categories? Anything posted between Jan 1st 2021 00UTC and Dec 31st 2021 23:59UTC

Any feedback?

11:48 PM

@cairdcoinheringaahing Ok

@Fmbalbuena Nice intro, could use a few testcases.

jk, codegolf.meta.stackexchange.com/a/24295/106959

Looks fine but give it a day or two

OK

ta Radvylf srik su shilani

seems like it's almost certainly a dupe of codegolf.meta.stackexchange.c…

@taRadvylfsriksushilani ...

11:52 PM

@emanresuA Another five-step sequence: CODE -> CODS -> COOS -> GOOS -> GOOF -> GOLF

caird coinheringaahing

@taRadvylfsriksushilani Nice :P

@taRadvylfsriksushilani You sort of got me, except that I always open links in a new tab and so I saw what that was before it started playing

ta Radvylf srik su shilani

Chat opens all links in a new tab anyway

@DLosc Nice :P

CMC: 1 or 2 only one is not rickroll

11:54 PM

@taRadvylfsriksushilani You got me good there

@taRadvylfsriksushilani But that focuses the new tab, whereas what I do keeps the focus on the current tab.

ta Radvylf srik su shilani

ah

I've noticed an advantage of having a slow computer/slow wifi is rickrolls take longer to load :p

3

On my chromebook I've got some time to react, but on my other laptop I have to act super fast or I'm out of luck

@taRadvylfsriksushilani this discovery may save alot of people across the internet

An update on using chat from a Windows phone: one of them seems to look like it'll charge properly. The other one doesn't seem to be reacting to having a charger in it

@taRadvylfsriksushilani The other thing is, when I clicked on it directly (For Science), I got an ad first.

11:57 PM

@DLosc adblocker is a double sided blade i suppose, ad was meant to protect you from being rickrolled

@Niko Truthfully, I'd rather watch 15 seconds of Never Gonna Give You Up than 15 seconds of most ads

Ok, finally went and made a rickroll blocker

Idea: ad blocker program that replaces ads with Rickrolls :P

ta Radvylf srik su shilani

Lemme guess...it's a rickroll?

Nope, it's a security error :p
