I have the perfect name for vycoder

Vyncode

Doesn't have any other search results and can plausibly sound like encode

Also, I've been doing some thinking about backwards compatibility for the compressor just in case we ever decide to refine the corpus or add new compression algorithms

When using the flags, the version can be set

And not including a version uses the latest version

And the version is inserted into the permalink, and displayed in answer templates

So something like

# Vyxal, 28 bits¹, 6.xx bytes

Where the superscript number changes to match the version

Multiple corpuses would need to be maintained of course

But it'd mostly just be a switch check thing

Now how the version gets passed as a flag is a good question

Maybe something like !{1} and ={1}

And what should the decode/encode flags be anyway?

I just chose ! for decode bits and = for use sbcs and encode

There might be more appropriate symbols

@VyxalBot you don't report rename events?

CMQ: Say you have a language that has programs that are strings of bits. And say that the string of bits can be any length, and that it is never guaranteed to be a length divisible by 2, 4 or 8. How do I store this file locally? And how do I read it? Note that bitstrings can't be padded to a nice amount of bytes, as padding changes program meaning.

yes, that is referring to vyncode :p

okay so on second thought, vyncode is going to be a jar offline

because turns out that js2py only does es5

scala.js outputs es6

@lyxal :O

it worked very well

would use again

:D

@lyxal wrong:

>>> js2py.eval_js6('let a = () => 11; a()')
11

> js2py.internals.simplex.JsException: SyntaxError: Line 16: ArrowFunctionExpression is not supported by ECMA 5.1.

I am not copy-pasting the entire 346kb file into the offline interpreter

and apparently, it says it's slow to execute es6

and the encoder is already slow

with js

sadge

12:54 PM

it goes nyoom with scala jvm

so now I'm once again rummaging through the v3 code base to steal stuff

!!/status

@Ginger I am doing what you told me to do. Argh, it takes so long.

The Vyncoder PR is now ready for review

I still don't understand how that works

Range coding (or range encoding) is an entropy coding method defined by G. Nigel N. Martin in a 1979 paper, which effectively rediscovered the FIFO arithmetic code first introduced by Richard Clark Pasco in 1976. Given a stream of symbols and their probabilities, a range coder produces a space-efficient stream of bits to represent these symbols and, given the stream and the probabilities, a range decoder reverses the process. Range coding is very similar to arithmetic coding, except that coding is done with digits in any base, instead of with bits, and so it is faster when using larger bases (e...

Basically, drawing patterns from the 1300+ vyxal answers on the site + other sites

ah, so black magic

Sbcs program in, bitstring out

@Ginger essentially

@lyxal the <sup>1</sup> indicates the first compression version of vyncode

Any changes to corpus or predictions would bump it to version 2

Basically, something scored under one version will always permalink the same

It's gonna be fun using this in the wild and seeing how people who haven't been following vyncode react to fracbyte vyxal

Yeah I've been wondering if there should be a meta discussion about whether mass edits of old answers should be allowed

Once this is all merged and live of course

Once it's merged, 2.21 can be released

what about v3?

2:03 PM

That's on the back burner for now

I don't like the "spawn a new process for vyncode" thing

feels too flimsy

what if no java?

@lyxal ah dang that should be more than 11 bits

what if installed from pip?

@Ginger online interpreter

@Ginger jar included

mmmmmmmmm

have you tested it with pip?

it just feels... wrong

Python projects should only be Python

I will stand by this statement

2:05 PM

@Ginger that's good if you don't need to have fronted python

but I suppose v2's going to be deprecated at some point

*frontend

GingerIndustries approved #1720 (Get a start on implementing fracbyte functionality.): "I don't like the Java-in-Python shenanigans, but the rest looks good."

Don't merge yet

I need to fix js output tomorrow

got it

2:06 PM

@VyxalBot how else am I supposed to have something both js and python understand and is also fast without having extreme code duplication

This way, the js and jar are from the same source

what's the deal with this PR?

Making test data nicer for vyxapedia

v3 test data

Right now, it's all in framework attributes

Whereas the v2 data is all in yaml

there's not been any work on it tho

There has

in March

2:09 PM

It just hasn't been worked on for a month

Neither has v3

I think we've all been busy with a thing called life lately

User and I have had exams, assignments due, that sort of stuff

I now have sleep due

well you go do that

3:07 PM

on this repo github.com/Vyxal/Vyncode theres a typo "fracitonal" in the readme and description

whoopsies

@Jacob fixed, thx

np

how do i save the input to be used later?

9:30 PM

@AlanBagel You probably want to use one of these ?⁰¹□ to access the input later

how do i use it?

for example vyxal.pythonanywhere.com/…

how does it work?
