@user Which one's L again?

user

Length? idk

Wait no it's top of stack joined by newlines

l is length of top of stack

emanresu A

Wait what

I confus

user

Like if someone uses jl to join the the stack and then get that string's length, how do you want it to work for infinite lists?

lyxal

It should just not halt

Also, I won't be able to be as active today, because I'll be out for a few hours

user

@VyxalBot See what I did in this branch was add a separator parameter to LazyList's output method so if you find the j flag you just call output.output(sep="") if the output is a lazylist, but if you want it to not halt, that's a lot harder ⍨

I'm available for the next 30ish minutes, but after that i might not be

user

lyxal

lol

@user it should be easy to not halt

If it's printing an infinite list, it'll not halt by default

user

Right but what do you do if you get l afterwards?

lyxal

It'll never evaluate

user

Or do you want it to do vy_print right when it gets the j flag and exit the loop?

Exit the loop it is then

[@lyxal: 60211083]
ALL flags should be used as is (no '-' prefix)
    H    Preset stack to 100
    j    Print top of stack joined by newlines on end of execution
    L    Print top of stack joined by newlines (Vertically) on end of execution
    s    Sum/concatenate top of stack on end of execution
    M    Make implicit range generation start at 0 instead of 1
    m    Make implicit range generation end at n-1 instead of n
    Ṁ    Equivalent to having both m and M flags
    v    Use Vyxal encoding for input file

user

Why do we even have the l flag anyway? Seems kinda cheaty

lyxal

For when you have an L at the end you want to get rid of

user

sus

(but really, I can't see why you can't just put an L at the end and take an L)

lyxal

A lambda followed by an L feels unsatisfying sometimes

Especially when it's at the end of a program

user

00:17

But unsatisfying things always happen, you can't make a flag for all of them

lyxal

It is what it is

Vyxal Bot

@Fmbalbuena Hello, World!

Fmbalbuena

@lyxal ^ polyglot?

lyxal

00:20

Looks like it

Fmbalbuena

@lyxal Explain in Vyxal?

user

Nice

lyxal

The print... part all does stuff to a bunch of 0s

The backtick string is pushed and the last " is ignored

Just use normal trash

Fmbalbuena

@lyxal Why?

Trash will be TLDR.

lyxal

Trash is shorter than `Trash`

user

00:27

I think that's my last PR for the day, then it's time to sleep and eat for me

Vyxal Bot

Lyxal approved on PR #658 (Vyxal/Vyxal)

Fmbalbuena

@lyxal This is recommended

lyxal

I'll use it next time

It might be beneficial to keep bursts of vyxal bot activity contained to the site

user

Meh, I don't think it really matters, but if it's a room where we're ROs, we could move "trash" back into Vyxal if necessary

lyxal

Ighto my mostly unavailability starts now

00:53

i think being able to move things back from trash is a somewhat overrated thing since i don't think we've had that need so far and you could just ask me

but yeah custom trashcan ain't a bad idea

what

no if people need messages moved from trash back to this room they can ask me since I'm automatically RO of pretty much every room I can see

user

01:32

What happens if you go blind? :o

Fmbalbuena

@user Nothing happens, but you can't learn Vyxal

emanresu A

03:16

@Fmbalbuena That should throw a parsing error...

user

04:02

@emanresuA could you nark shallow flatten done in the big chrcklist?

emanresu A

Btw for infinite output formatting I mean something like for item in result: print(item, end=' ') for joining on spaces for example

user

The formatting isn’t a problem, combining multiple flags is

emanresu A

Oh ok

user

But lyxal clarified that you exit the loop so /shrug

emanresu A

When userscript slow

user

04:15

Nah just movile

But i have definitely fgitwed tge userscript before lol

emanresu A

@user Oh lol

@lyxal I have a question

lyxal

If you ask it quickly enough I'll be maybe able to answer it

And if I can't I'll try again in 9 hours

mathcat

um no it'll probably take a bit time

lyxal

Ask

mathcat

okay

What are encodings? How do they define bytes? What encodings are valid for code golf? What do charactersets and codepages have to do about all this?

lyxal

Encodings are how computers interpret raw bytes

Or how they display them more accurately

The idea is that answers are actually just raw series of bytes

Meaning that Vyxal answers (and answers in non utf 8 langs) should be given as something like a hexdump

I say should, but I mean should very technically

Encodings make the raw bytes look nice

mathcat

13:25

hm okay. But why is Vyxal non utf-8?

lyxal

If you can make an encoding for your language that can run on a computer then it can be used

@mathcat because it uses all possible 8-bit combinations

If utf-8 was used, byte counts would become way longer

The idea is that a byte can only have 256 different values

Utf 8 has special rules for allowing bytes to be grouped together

Vyxal doesn't bother with that

Instead, it uses a custom SBCS

(single byte character set)

mathcat

So every character in Vyxal is one byte?

lyxal

In its own encoding, yes.

mathcat

nice

lyxal

Say your program was 7f 3a 1e 86 21 in raw bytes

If you use the vyxal encoding, it'll display as 5 characters

But if you use utf-8 encoding, it might display as only 3 or 4 characters

Even though it's the same program with the same byte count

mathcat

13:29

and last question: Are there any pros/contras for using utf-8 rather than a SBCS?

lyxal

Utf-8 allows a greater character set (millions rather than just 256)

But the moment you start venturing outside of ascii, characters become more than 1 byte

mathcat

oh, okay

nice thanks

lyxal

¡ is one byte using vyxal encoding

Two with ascii

That's technically a vyxal fizzbuzz

It's just presented using a different encoding

It'd need to be converted to raw bytes and the v flag would need to be used of course

But it'd work

mathcat

ok, I think I understood a bit, thanks

lyxal

₁ƛ₍₃₅kF½*∑∴ is what it looks like in Vyxal encoding

@mathcat see, that didn't take too long :p
