The Nineteenth Byte

12:00 AM

@user Sounds like letter-wise max to me.

@user admittedly that doesn't seem useful

@Lyxal Distribute letters of one to the entire other: "abc" * "defg" gives ["adefg","bdefg","cdefg"]

(this one works for strings of mismatched lengths, while the capitalisation things doesn't)

@Adám That sounds like a better idea. The transfer of capitalisation could be good for two byte multiplication

Lobsters

This also makes sense in the sense that a 1D string times a 1D string gives a 2D string.

12:03 AM

* even looks like the multiplication symbol. Unfortunately, it is again not very useful.

@user How does * look like the multiplication symbol‽

@Adám I meant the multiplication symbol in "practical" languages

⍨

"practical"

ngn

@Adám it's the closest to a vertically centred "."

12:06 AM

@ngn I'd argue ' is, but whatever.

ngn

that's too high

@Lyxal Have you thought up character-character multiplication? If so, you could do a vector product or something

IIRC the asterisk was centered vertically on original TTYs

@Adám thank you for the suggestion. I've pushed that functionality to main

You can still see it on fonts like IBM Plex Mono

12:16 AM

@RedwolfPrograms I'm not sure how much you can infer from that. Surely, the early screen-based terminals simply emulated the typewriter-based ones, then they in turn emulated type-setting, where the asterisk was high to denote footnotes.

Every once and a while I'll decide to post something in a non-SE forum and immediately realize why I don't do that

3:33 AM

@Lyxal interleave them

@Razetime do you have is the limited brain function?

Are you incapable of sentence comprehension

very likely

Because I literally said that I don't want Interleaving done with multiplication

Because there's a built in for that

I know lmao

@Lyxal does vyxal have regex?

it might be cool if multiplication distributes over addition

addition i assume being ocncatenation

3:42 AM

wouldn't that just be cartesian product

It's really impossible to search for it. Perhaps there's some Chinese blog post about it but...

@cairdcoinheringaahing is the the centering one?

definitely helps a lot

Could anyone give me some feedback on this sandbox post? It's got a downvote, but I can't tell why.

6:10 PM

@user Don't usually solve these questions, but some people might dislike the "compile-time" restriction, (which don't really get)

@Razetime I mean, that's the interesting part - doing it at runtime is kinda boring. Maybe I should extend it to languages other than Scala?

I'm not sure how doing stuff at compile time works

if you have an explanation handy that would be cool

For the example I gave?

Gimme a minute to add an explanation in

@Razetime I added some Java to it

nah in general, like maybe some links pointing to how to do things at compile time

or so

Basically, Scala allows type members just as Java has fields and methods. The type member Plus is like a method taking one argument. The argument it takes is another type that extends Num (the base class for Peano numbers)

6:17 PM

@user cool

Oh ok

Alright, I've added some links now. This article is probably the most useful if anyone wants to try it out.

Heck it's morning

Wus popping with everyone?

Math class

And I'm almost done planning my esolang's codepage and commands

it's 4 pm here but it's so cloudy that it feels like 7

@UnrelatedString Same. It appears we live in the same timezone.

Y'all are an hour ahead of me

uh, 3 hours to midnight here.

9:12 PM

@user shocking

16 o'clock here too

Hmm, that's odd, why is everyone here from time zones where it's afternoon/evening right now? What happened to everyone for whom it's night?

they're sleeping

Sleeping? We're programmers! :p

@Wezl I know, I was kidding.

9:17 PM

@RedwolfPrograms not me

purely amateur, but maybe the spirit is the same even if unemployed

I mean it's not like I have a job in programming either I'm fifteen

my age remains undisclosed but I'll admit I joined SE without reading the full terms and conditions

@Wezl There were important terms and conditions?

@user stackoverflow.com/legal/terms-of-service/public#age

nothing atypical for something that asks for an email

Oh, alright, I thought I sold my soul or something.

9:42 PM

@user you did but not to se remember.

You belong to the redwolf hivemind

How do you forget this?

We literally gave you tasty cookies and decent health care remember

I thought that was just my mind, not my soul too.

100% or nothing

Because I've already put my soul as collateral for a loan from a certain shady figure.

You are belong to us

I can't give it to you guys too.

9:43 PM

@user let me guess... Razetime?

@Lyxal Not unless Razetime's account is operated by Satan.

@user you'd be surprised

TIL Satan is a programmer from India.

(for legal reasons thats a joke)

I think Razetime would understand.

No offence @Razetime, by the way, we were just kidding. But if you really are the Devil, that's cool too.

10:14 PM

@user how much was the loan? how much is your soul worth?

@Wezl I'm not allowed to say that.

1 hour later…

11:19 PM

@Lyxal remember how you said I should make left square bracket the inverse of right square bracket

I just thought of an oddly funny consequence of one way I could go about that

actually no it's not that funny because I thought of it wrong

actually no still one way that could

yeah

so [] could essentially end up being a cast to boolean if we ignore the fact that there is no such thing as a boolean

@UnrelatedString wdym there's no boolean

there literally is no concept of a boolean value

or truthy/falsy values

except for the like 30 builtins I'm going to lift from Jelly that use them anyways

booleans are a waste, especially in a glfing language

now someone has to make a "glfing" language and call it glf because that's short

11:35 PM

Sounds glfy

I'm adding booleans to my golfing language, since it means I can overload the functions even more

@Bubbler snds glfy, bblr

@RedwolfPrograms I see a potential: let one built-in do two things based on the true/false-ness of an input. The two things should be carefully chosen though

(Such thing is often said as a bad thing in software design, but who cares here)

Not as much that, more like having other (less used) boolean operators like NAND without using up a whole code point

Everything is based on truthiness/falsiness still, so booleans are just like a free way to add a few operators

Just make sure they mesh with other types

11:43 PM

As in?

and that you actually have use cases lined up

@RedwolfPrograms True + "abc"

True + False

6 + True

[1, 2, 3, 4, 5] / True

Type cohesion is where it's at.

(An APL built-in that does 25 different things)

(and ~50 different things)

@Lyxal All of that should work fine, I've set aside certain operators like basic arithmetic and concatenation to not be overloaded so that you don't end up with weird issues

@Bubbler essentially a 2-byte operator

@RedwolfPrograms have you decided how types interact together?

11:46 PM

Yes, I'm nearly done planning it
