@bigyihsuan id like to think that ppl think the same way about me when they see my answers, replacing "go" with "desmos"

@emanresuA yoo im still doing calc too

language feature idea: a way to call a function multiple times and assign the result to multiple variables

like let a, b, c <some symbol> new Thing() would create 3 new Things and assign each one to a, b, and c

ehhh

seems situational enough that it might just encourage over-use

Q: Render numeric string/date/time using unicode block drawing characters

Am looking for a way to render numeric string/date/time using unicode block drawing characters like in example below. Ideally this could have been solved with a figlet font but couldn't find one. Height is 3 characters, width is as tight as in example below. $ echo "\n█▀▀▀█▀▀▀███▀█▀▀▀███▀▀▀█▀███\...

Unrelated String

but as part of a general pattern of being able to invoke something multiple times into a sequence, and destructure that? that's good

like let a, b, c, *_ = ($()) <$> cycle Thing::new

in the worst mix of python, haskell, and rust syntax i've ever seen

emanresu A

I thought that was valid haskell lol

Steffan

2:43 AM

@bigyihsuan yeah i always think that

Unrelated String

@emanresuA it can't parse the *, needs brackets for the list destructure, and interprets ::new as a type annotation

not to mention it's kinda meaningless for something to take an argument of the unit type considering everything about how haskell works

like if you have some kind of state monad that you're initializing the objects in then the way you'd do that in actual haskell would be like uh

[a, b, c] <- sequence $ take 3 $ repeat newThing

in a do block

probably

@cairdcoinheringaahing So far we've covered basic linear algebra and vector valued functions (a second time, we also did that in calc II, but minus cross products and some other things), no clue what's in the rest of the class, but it's also called "multivariable calculus" if that's of any use

@emanresuA Aren't you like 15? "Still doing calc" is hardly something to be ashamed of :p

emanresu A

14, and aiden's 13

So I guess yeah

Radvylf Programs

At least in the US, most people either never learn it, or don't until college. If you're a year ahead you might finish calc II in high school.

emanresu A

What's the content of calc II?

All I know is that I've done nz scholarship calculus

Idk what that translates to

Unrelated String

@emanresuA wait you're 14

i always thought you were at least like 17

incidentally i actually browsed esolangs wiki in like middle school but never heard of cgcc until i started having things to look up on so :P

Ah okay (year 4 is around 9 here)

Radvylf Programs

It might actually be around 9 here too, I'm usually one of the older people in my class

Aiden Chow

@UnrelatedString opposite for me, i heard of cgcc first before i even knew about esolangs

got introduced to esolangs through cgcc actually

I made my first esolang sitting on the floor in an airport. It was very bad.

Radvylf Programs

It was called "pipe". The "pipe" was just an accumulator, but I didn't know that word yet, so the analogy I used was that all of the operators were like a "pipe" that the data travelled through, being transformed by each operator

emanresu A

How old were you?

Aiden Chow

@RadvylfPrograms interesting analogy!

Radvylf Programs

@emanresuA Esolangs says it was 2019, but that doesn't seem right at all

i mean is that not roughly what shell pipelines are

When is it going to start being called the "twenties"?

Radvylf Programs

I still haven't recovered my sense of time. A dangerous mix of COVID lockdowns and getting older.

@emanresuA I already try to call it that. I'd guess probably as we approach the 30s we'll actually need a name for the decade

Right now we've gotten into the habit of using generations instead of decades, but since 2020 is kind of a defining year in our perception of time and culture, it's a great time to switch back to decades

Unrelated String

@RadvylfPrograms joke's on you, i never had one to begin with :P

@UnrelatedString come to think of it maybe this was the trauma that sealed off my creative writing abilities forevermore

Radvylf Programs

@UnrelatedString neither do I

hell, I wrote a whole challenge based on my lack of time concepts

Radvylf Programs

@UnrelatedString This reminds me of one of my first JS projects, a really simple text adventure game where every choice you made was an if-else block. The width of the jsfiddle text box was what limited the complexity lol

Unrelated String

that sounds basically like my first JS project as well

@AidenChow same here

I discovered esolangs.org from cgcc, and liked esolangs so much I got a phone case with limes on the back

Radvylf Programs

My intuition is that is is, via some really annoying BF reimplementation

Actually I think it's almost trivial. You could easily have three stacks within easy access using scopes. Use the first stack as the tape to the left, the second as the tape to the right, and the third as the current tape item and any intermediate state necessary for things like -

CMC: Work out why toString() in JS does what it does

Steffan

4:03 AM

wdym does what it does?

like commaifying arrays and stuff?

emanresu A

As in just toString()

As a code snippet on its own

Steffan

It just stringifies

Oh

x=>x+'' as a code snippet

emanresu A

Try running console.log(toString())

Radvylf Programs

@emanresuA window.toString

emanresu A

Have you tried running it?

lyxal

4:05 AM

@emanresuA just prints [object undefined]

emanresu A

That's part of the puzzle, yes, but window.toString() gives [object Window]

Radvylf Programs

Because it's no longer bound to window, just like how saving "abc".replace to a varaiable makes it not work

So without a constructor it defaults to some symbol whose name I forgot, which is undefined here

emanresu A

Correct

JS is weird

PyGamer0

what - lol

Steffan

Yeah, but toString.bind(window)() should work

Radvylf Programs

4:08 AM

Steffan

Yeah

PyGamer0

what does this refer to?

Radvylf Programs

window.length

Steffan

developer.mozilla.org/en-US/docs/Web/API/Window/length

Radvylf Programs

Okay TIL

That's real weird

Steffan

4:10 AM

It won't work in Node

Radvylf Programs

Node has no window

emanresu A

length has so many different purposes lo

Radvylf Programs

It does have a globalThis, but with significantly fewer things

emanresu A

I think there's either global or self as well

Radvylf Programs

Honestly window being imported by default is so dumb

Just make Math and document their own things instead of everything having to inherit from one global variable whose properties are always in scope

Ooh I just came up with the most cursed thing ever: a Proxyd window

So you could add barewords to JS, among other things

emanresu A

4:13 AM

Oh no

Radvylf Programs

Fortunately I don't think JS allows you to override window or globalThis with a different object

emanresu A

Phew

Radvylf Programs

Okay so for backwards compat you can overwrite globalThis but it doesn't actually use what you write to it as the global scope, just shadows the identifier

Whoa, chrome bug

xyz is undefined but still shows up in autocomplete

It appears that the autocompletion is based on globalThis instead of window, overwriting globalThis removes all window autocompletions:

emanresu A

weird

Radvylf Programs

The dream is alive

There are so many insanely cool possible applications of this

I'm going to have to play around with it tomorrow

Unrelated String

wha

i assume proxies are some kind of namespace object?

Radvylf Programs

They're sorta like wildcard getters/setters

You can define a function that gets called any time a property of the object is used in any way

You can even make non-functions callable

or constructable

Unrelated String

oh so the proxy is what gives it the wildcard getter and with is what puts that all in scope

Radvylf Programs

yeah

Okay weird, you can't make something that was never callable in the first place callable with a proxy, but you can override what calling does if it was callable

And since you csn completely mimic a second object using any other object with a proxy, which is pretty much what they're for, you can just use () => {} as the proxied object and make calling do whatever you want

...which I realize is actually extremely useless since you can already make calling a function do whatever you want since that's the whole point of a function

Well, useless for making cursed objects with Proxy, but useful for its intended purpose of making certain modifications to existing objects

You could fairly completely change JS's syntax with the with (proxy) trick, since getters can be impure

E.g., do_x, do_y, do_z would be a series of function calls, despite having no ()s

And if you use stored state, you could even make a sort of assembly language syntax: add, x, y; jmp, x; mov, y, $20
