No, that's not going to be part of the core language

emanresu A

How are people going to write it then?

Radvylf Programs

So in an answer you'd probably have an xxd of the catstruct code, and then you'd link to whatever transpiler you used and post the source code

emanresu A

I guess :P

Radvylf Programs

I might make a semi-official transpiler, but that won't be "catstruct", that'll be "pre-transpilation catstruct with Radvylf's transpiler"

emanresu A

In other news, I'm somehow now a RO of CG&CC Gaming

where can i read about catstruct, if anywhere

Radvylf has a gist somewhere

@RadvylfPrograms To enjoy this suffering yourself:

window.addEventListener("wheel", (info) => {
    info.preventDefault();

    window.scrollBy(0, info.deltaY);
}, { passive: false });

(Usually there's some sort of really ugly fake scrollbar too)

(And typically instead of deltaY they'll just make some number up and the scrolling will feel very unnatural)

thejonymyster

@Seggan how does H behave on odd / 0 / 1 length strings?

emanresu A

@RadvylfPrograms This is my normal scrolling lol

Radvylf Programs

Ah, are you on a mouse?

emanresu A

00:06

Trackpad

Radvylf Programs

Hmm. I guess for best effect you need to replace info.deltaY with 10

Oh wait, and with a Math.sign somewhere since that will only scroll down lol

emanresu A

Weirdly, scrolling doesn't work when I try fiddling with any of that

Oh well

catstruct programs consist of two parts:

- The structure of the program as a binary tree
- A list of operators

The binary tree represents dyads, monads, and nilads. There's two types of leaf nodes, one for nilads and one for inputs, which don't have an associated entry in the list of operators. This allows more complex implicit input and reduces overhead for functions.

^ Important context for that gist

thejonymyster

00:11

aha

Seggan

@thejonymyster returns the integer division result

@thejonymyster math

thejonymyster

@Seggan sorry, i misphrased

(odd/0/1) length strings

oh wait i see what you mean

Seggan

H3 = 1

@thejonymyster when needing an input not to be comsumed

see one of the example programs at the bottom

thejonymyster

ooh ok

Seggan

i think it was the hyperfactorial one

thejonymyster

00:16

so H"cat" => "c","at"?

Seggan

yep

lyxal

why longest at the back instead of at the front?

thejonymyster

how about H"a" and H""

is it ["a"] or ["a",""]

Seggan

@lyxal becuase integer division

thejonymyster

and is it [""] or ["",""]

is why i was askin

Seggan

00:18

2nd case in both

thejonymyster

works 4 me

lyxal

I wonder which is more useful: longest half at front or at back

Seggan

idk

thejonymyster

~~compiler flag~~

Seggan

but halving an integer does int div

so imo strings should too

lyxal

00:20

interesting

thejonymyster

challenge idea;
for a list of positive integers X, a "complement" of X is any list of positive integers Y such that X union Y is a list of consecutive integers with no repeats
e.g. [2,4,6,7,8] is a complement to [1,3,5]
any given posint list X has a smallest complement Y, which has a smallest complement Z... etc until you have the empty list

example:

[1, 2, 3,    5,       8,                13]
[         4,    6, 7,    9, 10, 11, 12]
[            5,       8]
[               6, 7]
[]

challenge: i dont know

caird coinheringaahing

Given a list X, output a complement of X?

Or, the "chain" of complements?

thejonymyster

outputting the whole chain seemed like a bit much to me? am i just off the mark abt that?

caird coinheringaahing

Seems like it'd just be repeated application of "output a complement"

Man bites dog

The phrase man bites dog is a shortened version of an aphorism in journalism that describes how an unusual, infrequent event (such as a man biting a dog) is more likely to be reported as news than an ordinary, everyday occurrence with similar consequences, such as a dog biting a man. An event is usually considered more newsworthy if there is something unusual about it; a commonplace event is less likely to be seen as newsworthy, even if the consequences of both events have objectively similar outcomes. The result is that rarer events more often appear as news stories, while more common events appear...

The "Examples of literal use in journalism" heading has a concerning amount of entries

lyxal

well after all, why not? Why shouldn't man be allowed to bite dog when dog bite man all the time?

emanresu A

I guess, yeah.

lyxal

@Neil actually there is a point

consider the case of "abcdef","daffodil"

o would return abcdef

@SandboxPosts I literally was thinking about making a challenge like this one the other day, @thejonymyster why are you reading my mind :P

wait that was the wrong NSP link I replied to

@SandboxPosts I meant this one, it is lyxal who is reading my brain

lyxal

05:49

because putting funny numbers into microwaves is a universal thing

anyone with even a grain of humour puts 3:69 instead of 4:09 like a normal person

des54321

I do think I have a good solution to that written in haskell now though

also on the subject of that post, I do think requiring the outputted times to be in order is sensible, partly as I have no idea how a solution that outputs them out of order would even work

lyxal

it could output ascending instead of descending

des54321

I suppose

another small question that pertains specifically to my solution is if a flat list (like [minute,second,minute,second,minute,second,minute,second....] is an acceptable output format

lyxal

that's something I was considering, and I don't know how I feel about it. On one hand, I'm totally fine with people coming up with creative ways to solve the challenge but on the other hand, it makes reading the output a little harder and doesn't exactly resemble the display of a microwave

I don't really know what complexity it has right now. My algo is really hard to analyse.

Is it basically a generator attached to a path finder (where the path finder is basically an answer to your original question)? Or are they combined or something?

I've made both versions. The generator attached to a path finder was able to generate up to 7 very fast, the combined version was able to get me 8.
