@AviFS I like this one too

Although I really like "Language of the weak" :P /s

AviFS

Thanks a bunch everyone! Posted!

DLosc

@cairdcoinheringaahing Haskell is one of those languages I've kinda wanted to learn and never gotten around to, so... it fits.

AviFS

@user Weren't you the one helping me write it up earlier?

@cairdcoinheringaahing Oh no! That's awesome

Slightly too long for the title anyway, but should definitely add to the CW of name ideas

user

9:03 PM

@AviFS I will neither accept nor deny that :P

AviFS

Well you're getting credit for it :P

See credits

user

So...may we write answers to the questions in the question?

caird coinheringaahing

That's sort of what questions are for - answering :P

user

@AviFS Thanks, I am particularly proud of the cocks I contributed to the question

@cairdcoinheringaahing lol

9:04 PM

I meant - should they all be CW things with a list of suggestions?

@cairdcoinheringaahing shuttlecock, cocktail, and a coconut

AviFS

Hey @JoKing!!

Just sent in a chat event idea. Was caird's

caird coinheringaahing

IIRC mods get notifications for new meta posts, so I suspect they already know :P

AviFS

Wait! We don't have a tag for events

Oh...

I'm just enjoying telling everyone tbh, haha

And I figured they might have some ideas/thoughts

Jo King

@cairdcoinheringaahing We do (but the mod symbol doesn't light up on mobile for some reason)

AviFS

GUYS! I'M FINALLY DONE

That was like an hour and a half of my life

Yup... 2 hours

Back to actually fun projects :P

I don't understand how you guys do this

A username

9:11 PM

I've spent longer on stuff like this

I did enjoy writing it

AviFS

Just on the explanation part?

A username

Yeah

AviFS

Ouch

A username

But it's funny that it has the worst score, it's just really well-thought out

AviFS

Yeah, I can def do that

A username

9:12 PM

It it my most popular answer

AviFS

Well, I upvoted

user

@NewPosts How does Learn You a Language for Great Good sound @AviFS?

AviFS

I didn't even read it

But upvoted :P

@user Caird added that!

A username

I've already repcapped today :p

caird coinheringaahing

@AviFS I had "Lang" instead of "Language"

user

9:13 PM

@AviFS rak did, actually

AviFS

@Ausername Show-off

Yeah.. we have to figure out what to do about those minor variations

I think I'll group them into families, just a sec

A username

I posted challenges today and yesterday, what do you expect?

Jo King

i like this idea. a good thought might be that the challenges don't neccesarily have to be new ones, you can also highlight existing challenges that don't have an answer in that language, or ones that do but might be improvable

rak1507

@user I didn't edit it in

user

Oh, if Avi was talking about the editing, then I did that

hyper-neutrino

9:16 PM

@cairdcoinheringaahing that only matters if i actually have an SE page open and am looking at it :p

AviFS

Here are the idea families

@JoKing Oooh, I really like that idea!

People could also collab on harder ones that don't have an answer in that lang towards the end

@JoKing Do you want to suggest that? I'm a bit written-out and I don't want to get a second wind!

TODO: Add JoKing's idea, someone & anyone!

Hmm, github doesn't recognize perl6 extension as .p6

github.com/GrayJoKing/Cascade

caird coinheringaahing

Isn't Perl 6 now Raku?

AviFS

Maybe, that does sound familiar

I don't really know what I'm talking about, tbh

I just noticed the 'other' by GH and the '.ph' by JoKing

I'm interested, how did you write that?

DLosc

@user As in, what was my coding process, or what tools did I use?

user

What tools did you use?

A username

That do be much cool

DLosc

9:49 PM

1) Esolangs article, 2) online IDE, and 3) my ASCII Piet translator which has switches for outputting both raw PNGs for the pretty picture and hexdumps of PNGs for the TIO interpreter.

Is Fishing on TIO?

caird coinheringaahing

Why do I get the feeling that you've used Piet before? :P

@Ausername Doesn't look like it

DLosc

@cairdcoinheringaahing The funny thing is, I've actually never written a program in Piet before today.

user

It's all good, someone else made it and then DLosc bought it from them :P

@DLosc Riiiiiiiiiiiiight :P

9:50 PM

How do ruby heredoc strings work again?

DLosc

I've seen it, read the Esolangs article, had a vague idea of how it worked... and I thought it was a shame that the current consensus here is that it should be scored by the size of the image file, when it's obvious that each codel is less than 1 byte of information. So I made a codepage for it.

BTW, if you agree that one-byte-per-codel is a better scoring method for Piet than "number of bytes in the PNG file," here's a meta post you can upvote. </shameless-plug>

caird coinheringaahing

> We should stop making up new scoring schemes for programming languages, which only serves to make things more difficult. Code golf contests are scored in bytes, so that's what matters. Everything else is artifical and prone to not take all details into account.

DLosc

@user It also helps that triangular numbers have a formula that's super easy to implement in Piet.

caird coinheringaahing

I stand by Dennis' answer tbh. I hate that so many languages have to have new ways of scoring, when there is a simple and easy way to score everything

DLosc

What's your opinion on all the languages with custom codepages?

caird coinheringaahing

9:57 PM

I think they make the encoding seem more complicated than it actually is

But I still use them, mainly out of convenience

DLosc

?

As in, the true form of the language is the (potentially unprintable) bytes, and the veneer of a mapping from those bytes to easily-displayable characters makes it more complicated?

caird coinheringaahing

"Custom code page" doesn't really mean anything. A Jelly program is just a collection of bytes (like all programs). You could use the standard Unicode characters to display it, but it wouldn't look as nice. Therefore, Dennis choose to "reassign" the characters that the bytes represent. But ultimately, “3ḅaė;œ» is just the byte stream fe 33 d4 61 ea 3b 1e fb

@DLosc Exactly

The number of times I've had "This is 7 characters, but not 7 bytes" commented below my Jelly answers is annoyingly high, because a lot of people don't get that custom codepages are just veneers

DLosc

That's fair.

APL did kind of open a can of worms there.

caird coinheringaahing

I may be a bit of a purist, but I maintain that if you have an interpreter which accepts a stream of n bytes that does what the challenge asks for, then you can claim a score of n. I don't really care about the arguments "Oh, but I can just write an encoder to do that, so why complicate it?" because I think that yes, you should complicate it if you want to claim that score

DLosc

So would you argue that ASCII Piet would be acceptable as a dialect of Piet iff there were a full interpreter that understood it, rather than a translator program whose output has to be fed into a different interpreter? (Not making any promises here, just hypothetically for the sake of argument)

caird coinheringaahing

10:06 PM

Yes

Things like shell piping and whatever (e.g. python unascii.py prog | python piet_interpreter.py) make it slightly more complicated, and I don't know enough about shells to pass informed judgement on those, but if people who do think that counts as a single language, I'll defer to them

DLosc

In any case, it would be easy enough to make a bash or PowerShell script that pipes the two together, and then you could call that script the interpreter.

What happened to #946 and 947?

caird coinheringaahing

While I welcome 945 and 948, please also say hello to 946 and 947 from me. They also deserve a great, welcomimg start of their career at SE. — rene Jul 28 at 20:47

rene welcomed them :P

But also, SE has close to 1000 total (former or current) staff, and 10 of them are on the CM team. I'm guesstimating that another 50 have, at one point, had a staff diamond. That's ~5% of their staff. I'd imagine that #946 is an accountant, or an intern or someone who is useful to the company, but will almost never interact with the communities in such a way that we'd need introductions :P

r/trees and r/marijuanaenthusiasts are a couple of good ones too :P

user

lol, aren't those the ones that got switched?

DLosc

11:17 PM

@user -5 bytes

caird coinheringaahing

Yeah, stoners "stole" r/trees, so a bunch of arborists created r/marijuanaenthusiasts as "revenge" :P

user

@DLosc Smart, thanks!

DLosc

@user You're welcome :)

Totally different approach from mine, BTW

user

Oof, I tried mapping, but f=x=>[...Array(x.length).keys()].map(i=>x.slice(0,i)) comes out to 53 bytes

@DLosc Hmm, I suppose yours yields the empty string naturally?

Anyone know how to get overlapping matches with regex in JS?

DLosc

@user Actually, no. The 37-byte version computes all the non-empty prefixes and then tacks the empty string on separately.

user

11:22 PM

Huh

DLosc

@user This all started because I found a really neat way to do it with regex, but unfortunately it's much longer in JS.

matchAll is a bit clunky.

user

It tells me matchAll isn't even a function :/

Whoops, nvm, I was using it on the regex, not the string

DLosc

It's a pretty recent addition, I believe

user

Oh, that's why TIO throws up

DLosc

(and don't get me wrong, it's much better than the previous options, from what I've seen)

@user Hint ;)

user

11:28 PM

Ohh

I assume it's something like x=>[...x].map((_,i)=>x.slice(0,i)) then?

Oddly enough, the output becomes ,a,ab, as if it's not a proper list anymore

DLosc

@user Yep, that's most of the way to my 38-byte version.

Oh wait... actually, I just found another golf so now it's 36.

Q: Flatten a parabola keeping the distances between points along the curve constant

Background Math SE's HNQ How to straighten a parabola? has 4,000+ views, ~60 up votes, 16 bookmarks and six answers so far and has a related companion HNQ in Mathematica SE How to straighten a curve? which includes a second part asking to move a point cloud along with the curve that we can ignore...

I wish this worked

@user Hm, interesting. But if it did, wouldn't it just be x.slice(0) a bunch of times?

Not in Python

reversed tho

user

I don't get why that prints the list weird tho

DLosc

11:41 PM

@Ausername My regex solution is s=>[...s.matchAll(/(?<=(.*))/g)].map(g=>g[1]) (doesn't work on TIO)

A username

Oh nice

user

@Ausername It doesn't put quotes around the string or brackets around the list for some reason

A username

What is ?<= again?

DLosc

Lookbehind

So basically it iterates over every zero-length match and puts the characters before the match in group 1.

But then I have to use an extra map to get the results of group 1 out of each match object, so it ends up too verbose.
