Would it be appropriate to add a community ad for an APL-only codegolf site?

DJMcMayhem

Of course

You can add a community ad for anything you like. If the community doesn't like it, it'll just be downvoted

Adám

@DJMcMayhem Cool. One of our customers ran a 9-hole codegolf tournament during our user meeting, and it was so well-liked that they want to make another one which is open to the public.

accurate description of how SE itself works lol

Question: I'm designing a golfing language attempting to be shorter than Jelly for certain types of challenges; what categories should I try to target?

I'm thinking mostly math, matrix, and array-manipulation

maybe sequence as well

ASCII-only

@HyperNeutrino ascii-art :P

HyperNeutrino

:P

no I'd never be able to beat Charcoal

you can see how my last attempt went

Also, does it make more sense for forks to associate left or right?

Magic Octopus Urn

@ASCII-only WTH is a vine.

HyperNeutrino

@MagicOctopusUrn you don't know what a vine is o_O

it's a video uploading platform where each video has like a 7 second limit or something like that

Magic Octopus Urn

@HyperNeutrino so it's a public snapchat?

HyperNeutrino

13:45

it was an interesting idea to share short funny films or maybe inspirational messages but it's dying I think

@MagicOctopusUrn sure?

Magic Octopus Urn

@HyperNeutrino odd... anyway, back to lurking.

HyperNeutrino

@MagicOctopusUrn pls first give me idea for in which general category of PPCG challenge I should try to have my language outgolf Jelly

Erik the Outgolfer

@HyperNeutrino that joke is becoming old...:p

HyperNeutrino

:P

but I'm actually planning on trying this time

@EriktheOutgolfer How does f g h j k l behave as a series of dyads in Jelly?

Erik the Outgolfer

at the very start of a line?

because in that case they behave differently

HyperNeutrino

13:49

like on its own

Erik the Outgolfer

like (f g h) j k l

f g h forks like g(f(x, y), h(x, y))

HyperNeutrino

ok so fgh is a fork and then what does jkl do?

(to rephrase my question, how does ð f g h j k l ð behave)

How to outgolf Jelly: Rename some of the atoms so that you get shorter builtins :D

Erik the Outgolfer

final result should be l(k(j(g(f(x, y), h(x, y)), x), y), y)

HyperNeutrino

ah ok

Erik the Outgolfer

like this for reference

HyperNeutrino

13:51

so my idea for my language is slightly different in at least one way

@EriktheOutgolfer thanks

Also ,,,,,, makes it slightly clearer

Erik the Outgolfer

hmm...

HyperNeutrino

1ð,,,,,,ð2 gives [[[[1, 2], [1, 2]], [1, 2]], 2]

Adám

@HyperNeutrino In J, A (f g h j k l) B is A f ((A g B) h ((A j B) k (A l B))) but in APL it is f ((A g B) h ((A j B) k (A l B))) (with f applied as a monad).

HyperNeutrino

ah ok thanks

Erik the Outgolfer

@HyperNeutrino yeah tbf I haven't really used a so long run of dyads

HyperNeutrino

13:53

mhm yup :P

Erik the Outgolfer

apparently it's doing the "fibonacci" thing there...

HyperNeutrino

in my language A (f g h j k l) B would look something like (((A f B) g (A h B)) j (A k B)) l B

@EriktheOutgolfer huh?

Adám

@HyperNeutrino OK, that's just mirrored J.

HyperNeutrino

so like it forks the first three to form a new dyad and then it forks (fgh), j, and k

Erik the Outgolfer

I can see it behaves like (,,,),(,)

HyperNeutrino

13:55

@Adám o

Erik the Outgolfer

@HyperNeutrino yeah

HyperNeutrino

huh

I wonder which one's golfier

Erik the Outgolfer

and this behaves likewise like ((,,,),,),,

HyperNeutrino

huh okay

TuukkaX

Once you use Jelly for a while, is it sufficient to understand a 25 byte program?

Just by looking at it for a while. Not a complex one.

HyperNeutrino

14:01

what do you mean by sufficient

TuukkaX

Not easy, not too hard.

HyperNeutrino

?

Erik the Outgolfer

if you have the tabs open sure

TuukkaX

I'm tired of writing scripts on my phone

Erik the Outgolfer

jelly is more like a "write-only" language :p

TuukkaX

14:02

I was thinking that Jelly could reduce typing...

HyperNeutrino

lol

@TuukkaX if you like copy-pasting 5000000 times sure

Erik the Outgolfer

reduce??? it uses unicode chars in its encoding

HyperNeutrino

but if you're thinking about using Jelly for production code, please reconsider your existence

you can't type most of the characters lol

TuukkaX

production - Jelly ? No such thing

HyperNeutrino

use Pyth to reduce typing

^^

TuukkaX

14:03

Yeah, but I could work around the unicode thing

Pyth sounds nice...

Erik the Outgolfer

with all chars though?

HyperNeutrino

you'd need a lot of copy-paste or you'd need a custom keyboard layout

TuukkaX

Custom keyboard would do it

Erik the Outgolfer

he's on a phone, not sure if such a layout exists?

TuukkaX

There must be. I'm running Android

HyperNeutrino

14:05

oh also I'm designing my language to use mostly characters that my keyboard supports

I think it's the Android Multi-Lingual Standard keyboard but idk

TuukkaX

Seems like a good thing to go for!

caird coinheringaahing

@EriktheOutgolfer Nah, if I try, I can decipher most Jelly scripts under about 30 bytes. Otherwise, I'm stumped :P

HyperNeutrino

I often forget which built-in is which

like is f with the dot filter-in or filter-out? (I know it's filter-out in this case because I just used it yesterday but still :P)

caird coinheringaahing

@HyperNeutrino Beat you to it. That's what Levant's (my new language) primary code page is designed around :P

HyperNeutrino

and like is A with the dot on top Any and All or is that the one with the dot under it?

@cairdcoinheringaahing lol my ideas have never been original

caird coinheringaahing

14:10

@HyperNeutrino looks at Proton, then at JavaScript and Python :P

HyperNeutrino

well that was designed to combine the best of both (also, Cheddar)

TuukkaX

@cairdcoinheringaahing Under 30, by head only?

caird coinheringaahing

@TuukkaX Normally yeah. It depends on the atoms and quicks used though

HyperNeutrino

@cairdcoinheringaahing Without looking on PPCG for my answer, decipher Ḋ=⁶Ḣ$¡UµÐĿ¹Ṛƭ€QY

@HyperNeutrino dequeue if the first character is a space, then reverse. Repeat that until the results no longer change. Next alternate between reversing and doing nothing. Finally deduplicate then join by newlines. And, without looking on main, I swear, I can tell you exactly what challenge that is for. The "Undress a string" challenge.

caird coinheringaahing

@HyperNeutrino Monadic or dyadic? I'm guessing dyadic, but just wanted to check

HyperNeutrino

monadic

what the heck

why am I using map, truthy, index

why not just filter

caird coinheringaahing

@HyperNeutrino Append and prepend 0 to the input list, then split at 3s. Call the helper link on each, then make that into a list of truthy and falsey values and index the argument into that list. Helper link: Is the index of that into 2 equal to the minimum of the list?

I'm not sure about that, that one is more difficult

HyperNeutrino

oh it is harder? huh

not quite; the s with a dot means "overlapping slices of length"

caird coinheringaahing

14:21

@HyperNeutrino Hehe

HyperNeutrino

lol

caird coinheringaahing

@HyperNeutrino Shhh, you're making me look bad :P

HyperNeutrino

so it appends and prepends 0 to the input list, and then slices it into overlapping slices of length 3. It calls the helper link on each, gets the indices of truthy values, and then takes elements from the original list at those indices. the helper link checks if the second element is equal to the maximum (if the middle is a local maximum). this program gets all local maxima

(I know because I wrote this code lol)

Airborne weather radar does much the same thing, at least the fancy ones.

(C# rawstring literals function like VB.NET string literals, in which the only escape sequence is "" to escape a quote mark.)

101

Q: Why can't Python's raw string literals end with a single backslash?

Technically, any odd number of backslashes, as described in the docs. >>> r'\' File "<stdin>", line 1 r'\' ^ SyntaxError: EOL while scanning string literal >>> r'\\' '\\\\' >>> r'\\\' File "<stdin>", line 1 r'\\\' ^ SyntaxError: EOL while scanning string literal It ...

AdmBorkBork

This is why PowerShell uses backtick as its escape key

Pavel

That's intresting. I like that.

Does powershell have rawstrings?

Can those contain a single backtick?

Geobits

15:28

@cairdcoinheringaahing I don't even python, but this seems to fit your weak rules: print r'\\'[0]

AdmBorkBork

Single-quote strings don't parse the string, only double-quote, so single-quote-backtick-single-quote is just a string literal composed of solely a backtick.

But can you imagine trying to write out Windows paths with backslashes if every one needed escaping? Ugh.

Hence, backtick.

Pavel

No it makes perfects sense

I like that a lot, actually.

@AdmBorkBork So single-quoted string can't contain single-quotes?

AdmBorkBork

@Pavel No, not that I'm aware.

Adám

Ugh, all these escape rules. APL strings are so simple: Single-quote-quoted. Single-quotes are doubled. Period.

Pavel

I think C# rawstrings might be the most superior.

@Adám So like C# rawstrings with single quotes instead of double quotes. Got it.

AdmBorkBork

15:35

@Pavel Huh. Apparently if you double-single-quote inside, it's counted as a single quote inside. So, guess I was wrong.

Adám

@Pavel Yeah, but extra @ syntax, and imho, single quotes are easier to read, especially when they need to be doubled. Compare @"Joe said ""Hello"" to me" to 'Joe said ''Hello'' to me'

AdmBorkBork

So PowerShell single-quote strings seem to function just like APL single-quote strings.

dzaima

This all quote talk makes me want to finally put my horrible unfinished language on github. But instead, now I'm gonna close all of PPCG so I could finally work on this project I should have done already. :p

@AdmBorkBork Seems so. But APL only has these, and no other strings. KISS.

Thomas Ward

Pavel

16:31

@Adám how do I put null bytes in string without \0

And there are times when I'd rather use \n over a literal newline

DJMcMayhem

Question: I'm about to write up a challenge that involves repeating some function on an array a certain number of times. The number of times you need to repeat it is very consistent except for with an input of 2. Should I say all inputs will be >2, or make people handle that edge-case?

(For more detail, you need to repeat the function until you arrive at the original array, which, if the array has length n, will always take n steps for odd n, 1 step for n == 2, and 2 steps for even n)

2 is just a weird edge case

dzaima

I'd say no to edge cases for anything because it distracts from the main goal, unless there's a good (and usable in code) reason for the edge case or the edge case is the point of the challenge.

DJMcMayhem

16:48

Well in this case, the reason for it is because it simply takes one step to return to the original array if it's length 2. Which is usable in code, but then answers couldn't precompute the number of iterations to run.

I'm not sure if that's a good or bad thing though

dzaima

Though I don't make many challenges, I try to allow any small potential variations or weird behaviour just to not give an advantage to languages which have a built-in to deal with the specific problem and to not disadvantage languages made for the challenge by adding silly restrictions. IMO a small edge case is as bad as only allowing output to STDOUT - some languages will benefit, some not.

DJMcMayhem

Hmm. Yeah, I'd agree with that. I'll just restrict it to >3 in that case.

dzaima

for example, SOGLs 1 byte ⁾ - subtract 2 - could benefit SOGL at an edge case for 2

but I guess ultimately golfing is about having the most built-ins :p

DJMcMayhem

Well, I can tell you that would not help in this case haha

Giuseppe

17:06

@dzaima well, as long as they're short

dzaima

@Giuseppe Well a 40 byte Mathematica answer that is two functions and syntax sugar is much more interesting than a complicated 15 byte jelly answer and can easily get more upvotes

Maltysen

@DJMcMayhem i don't see why that's a edge case

if u return to the original array twice

it'll be still the original arrray
