I have autocorrect disabled on my phone, yes

Also, I was typing with only my non-dominant hand, and my fingers were cold, dry, and shaking

lyxal

@user scastie.scala-lang.org/Uv8yGRs4Q5uxW007EyAuDg

Right hand side must be int

I need bigint on the right hand side

user

00:37

@lyxal Does BigInt(1) << bitsToAdd.toInt work?

lyxal

That might lose precision

user

How's that?

lyxal

bitsToAdd is bigint

user

Well ints go up pretty high

2^31 is nothing to sneeze at

Are we likely to have numbers bigger than 2^(2^32)?

lyxal

You never know

user

00:42

@lyxal Sorry about that before, I meant an extension method called ** on Int or BigDecimal ought to help

Isn't this just for encoding/decoding though?

lyxal

It's for raising 2 to the power of numbers

user

But this is only for the range coder thing, right?

lyxal

Yes

It requires arbitrary size numbers

user

idk how it works but is it actually possible for it to go up to 2^(2^32)?

Wouldn't that require having those many characters?

Or am I just not understanding how it works?

Wait let me look at it before I say more

2 days ago, by AndrovT

The encode and decode functions require BigInts to work so it's not straight forward to port it to JS

s/js/scala

Some internal values go up to int limits during the encoding

user

00:45

@AndrovT Does bits_to_add here go up to 2^31?

Great work on the encoder/decoder btw

lyxal

It really is good

I've been wanting something to compete with nibbles on a fracbyte level for a while

user

Sorry I meant this one, was looking at the original repo

Wait no that's Lyxal/

I thought there was a Vyxal/ fork

lyxal

There's a scala version in the org

user

lyxal

Androv's is the original, mine has a better corpus and the org one is a scala port

It's only going to scala because I need to access the encoder online without having to make server requests

And scala.js exists

user

00:54

@lyxal I just tried (bitsToAdd >> 1.toInt) and it works for me

Although it's supposed to be the other way around so nvm

lyxal

This is in absence of a 2**bigint method

user

imma commit BigInt(1) << bitsToAdd.toInt for now so it at least works

I'll leave a todo comment so we can chang eit later

lyxal

So either bitshift with bigint on the right or pow operator

Maybe spire is needed

user

Looking at the code right now, what's top?

lyxal

Good question

user

01:03

If it doesn't exceed 2^31 or whatever, then we can just do bitsToAdd.toInt and call it a day

lyxal

Probably an upper limit

@user I think it might

user

lyxal

But as I said, a pow operator would also work

user

Bit shifting is better

Is there any reason for binList accepting Ints rather than BigInts?

Because if it's okay to do binList(top.toInt, ...), then top doesn't exceed the max int, and bitsToAdd probably doesn't either

I'll just wait for Androv to respond

lyxal

01:20

@user oh dang that's probably a mistyped thing

Yeah we better wait

user

Made a commit with some minor changes

5 hours later…

lyxal

06:07

Okay so good news it's no longer making programs twice as long

Bad news is that it's still adding a bit to some programs and nowhere near the efficiency of the python

As in a literal bit

2 hours later…

AndrovT

07:52

@user it's always <= minBits

1 hour later…

lyxal

09:07

@AndrovT is minBits always less than 2^31?

AndrovT

09:25

@lyxal The default is 16 and it seems to work well enough

It is theoretically better with higher values but it get diminishing returns

but definitely below 2^31

The only values that need to be BigInts in the original python code are top, bottom and ranges (and acc in the decode funtion)

@Ginger I am doing whatever I feel like. You could try that sometime, instead of being a mindless sheeple.

@Ginger Restarting...

Ah'll be bahk.

Well, here we are again.

cool

@lyxal Vyxal supports some infinite arrays. But is it possible to use it in input, as in 05AB1E in this answer?
https://codegolf.stackexchange.com/a/260466/114511

The Thonnu

15:41

@lesobrod the 05ab1e answer doesn't have it in the input section, it has it in the header section

So I'm pretty sure you can do the same in Vyxal

@lesobrod just fyi, your solution would fail on e.g. 14 14 14 14 14 (more than four <15)

4 hours later…

lyxal

22:51

@lesobrod input can be placed on the stack before program execution
