@ConorO'Brien APL, 15 14 bytes

Conor O'Brien

Huh. J doesn't beat APL often.

Zacharý

At least from what I have seen, unless your going against ngn, Adám, or marinus, J tends to beat APL about 1/3 of the time

Conor O'Brien

I'm considering "optimally golfed" (or at least close to) solutions. J tends to be longer by a character or two due to ligatures, but also sometimes shorter due to having specific functions

Adám

3:48 PM

@ConorO'Brien True.

dzaima

@Adám I thought a train would be golfier, but I have absolutely no idea how to use them successfully.

@Adám does that count as 13 or 11 bytes - do the parentheses add to the byte count?

Zacharý

No, parens are not counted

Conor O'Brien

4:03 PM

@Adám Does APL have a builtin function plotting library?

Adám

@dzaima This one happens to be an unreadable mess.

@ConorO'Brien Dyalog APL has SharpPlot.

Conor O'Brien

oh, I see. do you happen to know how SharpPlot handles infinities in line graphs?

Adám

@ConorO'Brien My kids are occupying my computer, so I can't test right now, but iirc it just chops the top of an otherwise near-vertical line.

Conor O'Brien

oh don't let me trouble you. that sounds about right, thanks

Zacharý

TIL OEIS still uses the font tag.

Adám

4:21 PM

@dzaima The reason it is so complicated is that we⍴e missing the atop operator. A direct translation of @ConorO'Brien's J code is (≢⊢)↑⊣,(≢⊣)↓⊢ because Dyalog still has not added J's @ atop operator. If f⍤g was atop, it would be just ≢⍤⊢↑⊣,≢⍤⊣↓⊢.

Zacharý

$? And *we're

Conor O'Brien

APL doesn't have atop? How odd. Is that because trains can do that implicitly?

Zacharý

Oh yeah, I've wished that APL had an atop operator for the longest time (never knew what it was called though)

Adám

@ConorO'Brien (fg) is atop in APL and hook in J. f∘g / f@g is hook in APL and atop in J.

Conor O'Brien

Huh. is there any good reason for either style?

Zacharý

4:30 PM

Wait, what's a "hook"?

Conor O'Brien

(f g) y becoming y f g y

Adám

@ConorO'Brien Almost. I was talking of dyadic only.

Conor O'Brien

Oh. so x (f g) y becoming x f x g y

Adám

@ConorO'Brien Pretty arbitrary, I think. Although I do find atop to be more "basic" than hook, and so it makes sense that "nothing" is atop, but I still think an explicit atop is useful.

@ConorO'Brien Hm, ∘ isn't that either, it is x f g y

Conor O'Brien

Wow, never thought APL's hook was different from J's. The equivalent of that in J is x (f g@]) y

Adám

4:34 PM

@ConorO'Brien So I have a mistake in the chart?

Conor O'Brien

no, I've just been programming wrong for the past year >.>

Zacharý

What are the shaded cells,proposals?

Adám

I have my chart hanging on the wall behind my screens at the office to keep my head straight.

@Zacharý Yes.

Zacharý

What's @ATaco's progress on the taco badge?

Conor O'Brien

4:53 PM

@Adám Does Dyalog APL have the notion of inverse functions at all? Or has it not been implemented yet?

Zacharý

Somewhat? ⍣¯1. It domain errors on functions for which it can't find the inverse

Adám

@ConorO'Brien As Zacharý said, *: is basically ⍣ which works with negative numbers, but it can also take a function right-operand to determine "when enough is enough". We don't have a way (yet) for the user to specify an inverse of their function, though a couple of ideas have been proposed.

Zacharý

"their" is the user, right?

Wouldn't that cause problems with incorrect inverse specifications?

ATaco

Taco badge not yet acquired

Zacharý

Hope you get it soon, looks like you have 3 answers left to go :)

Or 2

Conor O'Brien

5:04 PM

@Adám I see. I'd highly suggest how J does it, but I'm not sure as to how APL-like that is

Zacharý

How's that? Only use ASCII? :p

Conor O'Brien

No, haha. Use a specific conjunction (obverse in that chart). f :: g has a regular function of f and an inverse of g

Adám

@ConorO'Brien Uh, isn't J's more limited? The only stop condition you have is when y=f y by specifying f^:_ (that's ⍣∞ for APL readers).

@ConorO'Brien You mean :. because f::g is try f and if that fails, do g.

Conor O'Brien

Do you mean f^:_?

Zacharý

Um ... power infinity? Does that work?!

Conor O'Brien

5:13 PM

And yes I do @Adám, haha

Adám

@Zacharý Yes, that just means ⍣≡.

Conor O'Brien

^:_ is roughly equivalent to finding the fixed point of a function

Adám

@ConorO'Brien :. is in my chart with ⍫ proposed for APL.

Zacharý

@Adám Oh, okay

Conor O'Brien

@Adám to your first question, what else do you expect the inverse/obverse to do? And why mention stop conditions? I'm a bit confused

Adám

5:16 PM

@ConorO'Brien But how do you apply f until the value stabilises but the sign alternates each turn?

Conor O'Brien

That by definition has no fixed point, so it should throw a limit error

Zacharý

On an unrelated WTF note: there are OEIS sequences for n-1 to n-40

Adám

@ConorO'Brien They have nothing to do with with each other, except that the power operator/adverb can invoke inverses. I have another idea as to how to specify inverses.

@ConorO'Brien Well, in Dyalog APL f⍣g y applies f to y until y g f y. So application until the sign swaps, is f⍣(=∘-).

Conor O'Brien

In that case, you could do (|@f)^:_, that is, fix point for the absolute value.

Adám

@ConorO'Brien OK, that's a specific case. I'm trying to show a general idea.

@ConorO'Brien OK, how about append itself until the sum is at least 100?

CMC: Given a numeric list with sum>0, append it to itself until the total sum is at least 100.

E.g. [3,1,4,1,5,9,2] → [3,1,4,1,5,9,2,3,1,4,1,5,9,2,3,1,4,1,5,9,2,3,1,4,1,5,9,2]

CMC: Given a numeric list with sum>0, append 2×it to itself until the total sum is at least 100.

E.g. [3,1,4,1,5,9,2] → [3,1,4,1,5,9,2,6,2,8,2,10,18,4,6,2,8,2,10,18,4,12,4,16,4,20,36,8]

Conor O'Brien

5:28 PM

,~^:(100>:+/)^:_ should be what you are asking

Zacharý

(⊢,+/)⍣{100≤2×+/⍵} ?

Adám

@ConorO'Brien Ah, I see. But in Dyalog APL, you can do with just a single power ^.

Conor O'Brien

In general, using the power as a condition combined with a fixpoint can simulate loops

Wheat Wizard

@LeakyNun This is a place where I felt logical programming really paid off. I'm happy with the result

Adám

@Zacharý You mean ,⍨ or ⊢,2∘× depending on which CMC.

Leaky Nun

5:30 PM

@WheatWizard nice

Zacharý

I misread it.

SOrry

I appended the SUM to itself until the total sum was >= 100

Adám

@Zacharý My "it" wasn't clear. Could be the sum or the list.

Conor O'Brien

@Adám In J, instead of overloading u^:v to be a loop, u^:v(y) is just u^:(v y) y, e.g., <:^:* would move a number 1 step closer to zero. E.g., 3 -> 2 and -2 -> -1

Adám

@ConorO'Brien Right. I'm missing that operator/adverb in APL sometimes.

@ConorO'Brien That's a use-case for a hyperator (higher-order adverb) so that f op X g y is (f op (g y))y.

Zacharý

@Adám The latter could be ⊢,+⍨, right?

Adám

5:39 PM

@Zacharý yes, I always forget +⍨ and ×⍨.

Conor O'Brien

@Adám does APL allow the user to define hyperators? That's a cool feature

Zacharý

That's a proposal

And technically, it already exists with tradfns

Adám

@ConorO'Brien The syntax exists, it just isn't enabled yet.

@Zacharý How so?

Zacharý

I'm just misremembering that conversation, sorry!

Adám

@Zacharý Although you can fake it with "gerunds" (i.e. stringified operators).

Conor O'Brien

FlipTack

@ConorO'Brien Only nested to one level, or arbitrary?

Arbitrary.

@FlipTack Hi ⊖⊢

Catchy nickname

Your nickname is ~ṭ in Jelly :PO

Zacharý

5:55 PM

Since it's arbitrarily deep: Adám's other solution is invalid as well

Why don't we ... adám up and make his nickname (⊖⊢) + (~ṭ)

Adám

@ConorO'Brien Wait, do we have to just concatenate the items of the outer list, or do it on each level

Zacharý

Each level

Mr. Xcoder

I was thinking of equivalents to "Niladic" and I though of "Zero", then I thought of arity => "aric". Joining them I got "Zeroaric", but that din't sound well so I switched to "Zacharýc" :P

Conor O'Brien

@Adám the resultant list should only have 1 level (it should be a flat array with scalar elements). that is, 1=⍴⍴ result

Zacharý

Like I said before (mostly because I'm proud): MY, 3 bytes: ωḟ←

Conor O'Brien

5:58 PM

@Mr.Xcoder nilary perhaps

Mr. Xcoder

...nah... Still thinking

Conor O'Brien

how about "void"

Adám

@ConorO'Brien No 1=≡. ⍴⍴ is rank, ≡ is depth.

Zacharý

Nulladic?

Mr. Xcoder

@ConorO'Brien Nice... But not plain "Void"... I'll make it "Void<something>"

Zacharý

5:59 PM

Voïdic?

Mr. Xcoder

Voidaric :)

Conor O'Brien

voltairic

@Adám I'm not sure of the APL specifics, but I'm pretty sure ⍴ is the shape; a flat array has a shape of a single element, so 1=⍴⍴ determines a flat array.

Zacharý

No ... nested != multidimensional in APL

Mr. Xcoder

Voidic functions. Thanks to both of you

Adám

@ConorO'Brien Nope. APL is just like J in that respect. $$ isn't the depth.

Conor O'Brien

6:01 PM

well J doesn't have nested arrays either so I'm grasping at straws :P

Mr. Xcoder

Nah... Got it! Invariadic functions!

Adám

@ConorO'Brien Sure it does 'a';<'b c'`

Zacharý

Wait ... J doesn't have nested arrays?

Conor O'Brien

That's a boxed array, not a nested array. From what I've heard of APL, it has its own concept of nested arrays, right?

Adám

@ConorO'Brien The difference between boxed and nested is very little.

Conor O'Brien

6:04 PM

But there is a difference semantically. Specifically boxed arrays like you are talking about behave differently under the shape conjunction. I assumed APL arrays acted liked J arrays, that they would behave something like the following:

   i.4 4
 0  1  2  3
 4  5  6  7
 8  9 10 11
12 13 14 15
   $i.4 4

   $$i.4 4

   1=$$i.4 4

   i.16

   $i.16

   $$i.16

   1=$$i.16

Adám

 2 1  2 2  2 3  2 4
 3 1  3 2  3 3  3 4

      ⍴⍴⍳16
1
      1=⍴⍴⍳16

Conor O'Brien

so 1=$$ does determine a flat array...

Zacharý

Shouldn't this go to the APL room?

Conor O'Brien

naw, only if people have something better to talk about

Adám

@ConorO'Brien No, just like it doesn't in J!

Zacharý

6:07 PM

1=$$ is true for flat arrays, but that does not mean 1=$$ is false for non-flat arrays, from what I gather

Adám

   $$(<1 2);<<3 4

3 mins ago, by Conor O'Brien

But there is a difference semantically. Specifically boxed arrays like you are talking about behave differently under the shape conjunction. I assumed APL arrays acted liked J arrays, that they would behave something like the following:

can you confirm as to whether or not my assumption is correct? that APL has a distinct notion of nested arrays from boxes?

I am not including "boxed arrays" in my definition of nested arrays

Zacharý

I might be dead wrong here: enclosed within a scalar?

Conor O'Brien

no doubt that I'm wrong as well, I'm primarily confused

Zacharý

And that's why I don't program J, folks!

Adám

6:11 PM

Right, the main difference between APL's nested and J's boxed arrays is that APL doesn't let you enclose a simple scalar. Also, J doesn't let scalar functions/verbs operate on boxed data, while APL lets them penetrate.

Conor O'Brien

alright, I had thought there was a difference in the way APL counts its nested arrays in terms of shape. guess not

@Zacharý because of a programmer's confusion ? :P

Zacharý

And because of the way they call things. Can not stand calling things in programming nouns, verbs, adverbs, conjunction, gerunds ... blech!

Unless your programming AppleScript or something

Conor O'Brien

you don't have to use those names while programming in J :P

Zacharý

While reading docs on J...

Conor O'Brien

true enough

Adám

6:16 PM

@ConorO'Brien No, maybe you're thinking of K? K only has one type of "layers", where APL and J have two.

Zacharý

And $850, it's not likely to get $850 programming J :p

Conor O'Brien

oh, that might be it. :/

@Zacharý programming in J is its own reward young padawan

Adám

@Zacharý I jet a lot more programming APL than $850.

Zacharý

I know that, you work there! But how does one "jet" money?

Adám

@Zacharý Not "there". There are many places one can make a living off APL. Speaking of which: Who wants a job with 80% programming APL + 20% learning APL — after half a year's intensive (paid) APL training? Job is in New Jersey. Company is HUGE US corporation.

Conor O'Brien

Zacharý

Adám

@ConorO'Brien ?

Zacharý

That APL programmers actually program for "HUGE" corporations.

@Zacharý Not certain. It is hard to find people who are willing and able.

Conor O'Brien

355 miles and a good amount of school is in the way :P

Adám

@ConorO'Brien Ah, that's because they are enumerations rather than values.

Zacharý

7:00 PM

@ConorO'Brien For the latter portion, same here.

Conor O'Brien

@Adám oic

Adám

@ConorO'Brien Here:

]chart (⊢,!)¨.001×⍳5001

Conor O'Brien

ah, much better. I'm assuming this uses a fork?

Adám

@ConorO'Brien Yes. APL forks are the same as J forks, i.e. 3-trains.

Conor O'Brien

yeah

Zacharý

7:58 PM

Is it common to have a website that is just your last name? I'd assume they're already taken

Adám

@Zacharý Depends on your name. Mine is certainly available. Hm, adam@brudzewsky.net wouldn't be bad…

Zacharý

Yeah. Taylor would DEFINITELY be taken.

Conor O'Brien

not if you find the right website extension, perhaps

Zacharý

... Could be worse ... could be Smith or something ...

CMC: Anybody here actually own a website right now?

Conor O'Brien

it could also be "Wolfeschlegelsteinhausenbergerdorff"

Zacharý

8:07 PM

Um ... why did that come to mind?

Conor O'Brien

imagine owning "Wolfeschlegelsteinhausenbergerdorff.co.uk" or something

Zacharý

The cook islands, .ck uses the .co. convention as well... who made THAT bad decision?!

Adám

@Zacharý >Domains considered profane will not be considered on any level, and the application will be dissolved with the applicant being notified, and future requests for the same domain name will be ignored. '.ck' domains are monitored on the web, on a regular basis for profanity on the Internet if it is found to be doing so, or if the site is deemed inappropriate, the domain will be terminated without notification or refund.

@Zacharý APL, 1 byte: 1 (Dennis, e.g.)

Conor O'Brien

@Adám Retina, 0 bytes:

Adám

@ConorO'Brien Yup, I'm outgolfed.

Mr. Xcoder

8:16 PM

Any esolang creators with codepages around? If so, would this (the decode function) be a valid codepage creator, so that all the 256 characters can be represented as one byte? Since each character maps to an integer in the range [0, 256), and 255 is the highest integer which can be encoded in at most 8 bits.

IMO it is fine, right?

Leaky Nun

@EriktheOutgolfer why did you delete this answer though

Erik the Outgolfer

@LeakyNun because there's a sneaky dupe and I hate duping answers

Conor O'Brien

@Mr.Xcoder I think you still need to be able to read a file of raw bytes and interpret that in your language

Leaky Nun

lol

Mr. Xcoder

@ConorO'Brien Sorry, I am slow-minded. Example?

For instance, this is how Jelly does it:

def unicode_to_jelly(string):
	return ''.join(chr(code_page.find(char)) for char in str(string).replace('\n', '¶') if char in code_page)

I realised I am not sure how codepages work...

ah... >_<

Anyway, gtg now

Probably it will end up being ascii-only

It just took me 18 hours to update to ghc 8.2.2, it better be worth it.

Leaky Nun

CMC: given a positive integer smaller than 26, output the correct inclusion-exclusion formula. E.g. for 2, output |A∪B|=|A|+|B|-|A∩B|; for 3, output |A∪B∪C|=|A|+|B|+|C|-|A∩B|-|A∩C|-|B∩C|+|A∩B∩C|. You can use other symbols than ∩ and ∪; you can use lowercase instead of uppercase.

Wheat Wizard

Since addition is commutative can we output them in a different order?

Leaky Nun

yes

@Zacharý Yes why

@Blue You changed your username to Blue but the first sentence in your bio is Hi, I'm muddyfish. :P

Wheat Wizard

@MartinEnder How would you feel about a Hexagony + Klein language? There would be a total of 360 different topologies.
