Is there a general "Interpret another language" challenge? I know that this challenge exists, but the language I want to interpret is actually a BSM due to a built-in memory size limit.

Is it okay to post quite a few challenges to the Sandbox like I've been doing, or should I slow down a bit?

Aaroneous Miller

02:47

@mathscat I'd have to go with this one. It's a bunch of gobbledygook, not to mention Vim is already intimidating to a programming beginner, even when you aren't using it like this. (and yes, I do consider Vim to be a praclang, just not in the traditional sense)

@Someone its fine

Someone

@Seggan thank you!

Golf an HQ9+ transpiler There was a prior question about golfing an HQ9+ compiler that translates HQ9+ code into the language it is written in, but that was closed as a duplicate of the interpreter challenge because converting an interpreter to a compiler is seen as trivial. This question is base...

Oh, the arbitrary quine requirement is evil

Someone

03:27

@bbrk24 it's not too hard in JavaScript; not sure how it will go for other languages

Doing it in a language that can't stringify functions would definitely be harder

Seggan

i.e. almost all

Someone

Is using eval in a quine normally considered cheating? If it is I'll make an exception for that

Seggan

i dont think so

Someone

Okay, I'll leave it as it

noodle man

yeah eval in quines is normal

Someone

03:34

s/it/is

Okay thank you!

noodle man

stringifying functions is a weird JS thing btw

Someone

Does it have a purpose other than making quienes a lot easier?

s/quienes/quines

noodle man

probably for debugging

Someone

That does make sense

noodle man

if people just do console.log(something) so they don't just get object Function

since JS lets you pass a value of any type to any function and just have it get converted

Bbrk24

03:44

To be fair console.log inspects the object anyways in browsers

console.log({a:1}) doesn't just say object Object

@SandboxPosts how would the output for the Q command be scored?

Neil

both eval and stringifying count as cheating in my book, because you're using data as code or code as data, which a true quine (e.g. one written in C) doesn't do

Encode PSK31 Given a string of ASCII text as output, encode it in BPSK31 using Varicode. If it is possible in your language, play the audio over the device speakers; otherwise, output an audio file in any common format in a way that is typical for your language.

ooh, YouTube finally fixed an annoying bug

math scat

14:20

which one?

Seggan

the one where they block adblockers?

noodle man

17:00

why was this edit made? it removes the restricted-source tag, but the challenge is clearly restricted-source

CMC Meta-cat but generated program has linear length to input and bounded amount of non-zerowidth characters

noodle man

what do you mean by: bounded amount of non-zerowidth characters

Neil

17:17

@mathscat the one where it would auto-advance off the end of a playlist if it contained an unavailable video

math scat

huh

l4m2

@noodleman bounded amount: There exist N such that for any input, the amount is <N. non-zerowidth characters: visible characters(counterexample: U+200B)

Neil

the content creators I watch often queue up a playlist of pre-recorded episodes to become available in the future. it used to be that if you watched such a playlist, then when you got to the last episode, the ui for auto"play" would appear, but be nonfunctional

(auto"play" is what YouTube calls auto advance to its suggested next video)

noodle man

i hope they fix the bug where if you click "block this ad" and it shows you the pop-up that you won't see that ad again, it proceeds to show only that ad for the duration of the video

l4m2

@noodleman or say do thing like github.com/lorossi/zero-width-steganography

noodle man

got it

Q: Ungolf the Wind

Weather conditions at airports are reported to pilots in METAR (METeorological Aerodrome Report) format. This format could be described as being "golfed." Here are some examples: METAR KPDX 241653Z 16003KT 1/4SM R10R/4500VP6000FT FG SCT000 01/M01 A3040 RMK AO2 SLP293 FG SCT000 T00061006 $ METAR ...

math scat

May the program only output the parsed wind or does it have to pad that info in?

Someone

@mathscat I'm not sure I understand your question? The parsed wind data is the only output.

@SandboxPosts Doing a quick drive-by Sandboxing here. The challenge itself is very easy to understand, the implementation less so. Mainly just checking that it's clear enough, will probably post within a day or two on main if so

@Someone okay, thx

math scat

19:35

uhhhhhh

lol

sus

okay wtf

math scat

bruh

I don't think we're allowed to do that?

Ginger

is this going to continue for the rest of the month lol

math scat

How strict is AOC's licence?

Ginger

IIRC the challenges are free to use

but reposting them just feels sleazy

emanresu A

... But copying challenges from elsewhere or asking for help with them is explicitly not allowed here

Not to mention they're invalid anyway, quite unclear

@mathscat just use a custom reason

eh too dank, I'll let yall handle it

I have an HQ9+ to Python transpiler that supports the arbitrary quine function fairly easily using an exec-based solution; it's a 361-byte JavaScript function and gets a score of 890

This is `QQQ` in Python: `c='print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");';exec(c)
c='print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");';exec(c)
c='print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");print(\'c=\'+repr(c)+";exec(c)");';exec(c)`

BTW why is it showing that I have 29.4k rep? I don't have that on any site, certainly not here.
