Is it time for a commit message saying "man unfrick trig?"

lyxal

00:30

Maybe... :p

Fmbalbuena

02:05

@lyxal

I want to learn, @lyxal

lyxal

Do you know how to write an if statement in Vyxal?

Fmbalbuena

yes

lyxal

Okay and how about a for/while loop?

Fmbalbuena

!!/help

Vyxal Bot

All of my commands start with @VyxalBot or !!/
- Use "ping me" or "don't ping me" to add/remove yourself from the ping list
- To evaluate Vyxal code, use "(execute|run|run code|evaluate)", followed by code, flags, and inputs inside inline code blocks (multiline code is not supported; provide multiline input in multiple code blocks)
- For a full list of commands, see https://github.com/Vyxal/VyxalBotSE/blob/master/instructions.md

lyxal

(I'm just asking so I can determine what to teach)

Fmbalbuena

(|)

I Know but i forget the syntax

lyxal

(variable|code)

{condition|code}

Fmbalbuena

oh i don't know

lyxal

02:17

Would you like me to explain the loops?

Fmbalbuena

yes

lyxal

Okay so there's two main kinds of loops: for and while loops

For loops pop a value off the stack and executes code for each item in that value

Numbers are converted to ranges btw

Fmbalbuena

i know for, each and while

lyxal

I know, but I'm just explaining how they work in Vyxal

So for example:

!!/run 10(1,)

Vyxal Bot

[@lyxal: 59604965]
1
1
1
1
1

lyxal

So then you're probably wondering how to get the current value it's iterating over

You can retrieve it using n

n is the context variable - it stores the arguments for the current structure

Fmbalbuena

or duplicate the stack?

lyxal

!!/run 10(n,)

Vyxal Bot

I mean like that

!!/run `String`(n,)

Vyxal Bot

[@lyxal: 59605003]
S
t
r
i
n
g

lyxal

See how n gets the current iteration value?

Fmbalbuena

No, no, it's fine. Experimentation is what helps you learn :)

Fmbalbuena

Vyxal is my favorite golfing language but not favorite programming language

lyxal

I'm happy with that

Anyhow, you can also specify the variable name for the loop if you don't want to use n

hyper-neutrino

despite everything i've said about lacking all the builtins I want it is actually one of the few golfing languages i can use

Fmbalbuena

@lyxal See my about

@Fmbalbuena :)

@hyper-neutrino well the lack of built-ins is purely from a lack of knowledge of built-ins that's still present from version 0 lol

hyper-neutrino

lol yeah

lyxal

Like version 3 will obviously have a better built-in set, because I know a whole lot more than I did when I first made vyxal, and before May even

Fmbalbuena

@lyxal why why

lyxal

02:27

@Fmbalbuena you want E instead

But that won't work online because the online interpreter is sandboxed for server safety

That works in the offline version though

Fmbalbuena

@lyxal how many easter eggs there are in vyxal

!!/run lyxal

lyxal

@Fmbalbuena I would say not that many but I don't really know

hyper-neutrino

wait did the thumbnail change?

lyxal

@hyper-neutrino yep

hyper-neutrino

02:29

interesting

lyxal

It changed quite a while ago (read: a few months)

hyper-neutrino

ah

lyxal

@Fmbalbuena yeah that's something hyper special-cased for the bot

Fmbalbuena

!!/run `@hyper-neutrino` ^

!!//hyperping

Vyxal Bot

@Fmbalbuena @hyper-neutrino

lyxal

02:32

That's because @ is used for function definitions and function calls

!!/run @triple:1|3*; c ``

Vyxal Bot

[@lyxal: 59605100]
0

STDERR:
global stack, register, printed, output, MAP_START, MAP_OFFSET, _join, _vertical_join, use_encoding, input_level, raw_strings, retain_items, reverse_args, this_function
def FN_triple(parameter_stack, arity=None):
    global context_level, context_values, input_level, input_values, retain_items, printed, register
    this_function = FN_triple
    context_values.append(parameter_stack[-1])
    parameters = []
    parameters.append(pop(parameter_stack))
    stack = parameters[::]

lyxal

As you can see, that's what it transpiles as

!!/run @triple:1|3*; 7 @triple;

Vyxal Bot

@lyxal 21

lyxal

And that's how you would call it

Fmbalbuena

@lyxal gtg

lyxal

02:34

Okay then, see you soon!

detailed explanation of function parameters btw

PyGamer0

04:17

@lyxal i learnt a lot after i joined tnb

lyxal

05:08

Mmm yes implementing custom floating point equality for test cases got me feeling good

lyxal

06:01

haha when you were using python default equality meaning it wasn't actually catching things like l returning a bool instead of int for two non-numbers

so that 59 failed is actually 61 failed

hey wait what

61?

wow

by fixing the processor, I didn't break too much

* I didn't reveal too many bugs

lyxal

06:23

Protip: don't do test case fixing until I upload my updated version

Razetime

08:40

@lyxal this is a thing? am I helping out here as well?

lyxal

09:55

@Razetime it is

Also, user's bounty as well

yesterday, by user

Once I get enough rep, I'll give 50 rep (only once, though) to anyone who fixes 5 elements

lyxal

10:22

@Razetime which answer do you want your bounty on

Because as you can see, that's 6 elements you implemented

And last time I checked, 6 is more than 5

Here I'll check again just to be sure

!!/run 6 5>

Vyxal Bot

@lyxal 1

lyxal

Yep 6 is more than 5

Meaning you're eligible for the one time bounty

lyxal

11:46

fun story:

0

A: Digit small numbers

Vyxal, 11 bytes KḂZƛṅL;?L>A Try it Online! Hmm yes Jelly porting goes brr. Explained KḂZƛṅL;?L>A K # factors_of(input) Ḃ # that, and that reversed Z # zip those two -> pairs of factors that have product = input ƛṅL; # join each on spaces and take length ...

it was originally 16 bytes

but then caird posted a 14 byte Jelly answer

which was originally 15 bytes

so I took that 2 byte beat and used it against caird with a 3 byte beat

code golf marxism ftw I guess

(that's a joke)

(that's in no way a political statement)

Fmbalbuena

12:14

@lyxal

lyxal

yes

Fmbalbuena

Can I learn vyxal?

lyxal

sure

so we left off on for-loops

and functions

to recap:

!!/run @triple:1|3*; 7 @triple;

Vyxal Bot

@lyxal 21

lyxal

that defines a function named triple that takes 1 parameter

and it returns that parameter times 3

so the next thing to note is that parameters can be named

that is, you can make it so that parameters can be accessed through variables

Fmbalbuena

12:17

What is the ASCII Number of o/

lyxal

you mean

!!/run \oC

Vyxal Bot

@lyxal 111

lyxal

or do you mean

!!/run `o/`C

Vyxal Bot

@lyxal ⟨111|47⟩

Fmbalbuena

no, decode String without letter "D".

lyxal

12:18

do you mean get a compressed string without using øD?

Fmbalbuena

"ø"

!!/run `ø`C

Vyxal Bot

@Fmbalbuena ⟨⟩

lyxal

Fun fact: there's a language bar that gives you all the characters of vyxal: abrudz.github.io/lb/vyxal

that's what it looks like

notice the character bar at the top

but to answer your question:

!!/run `\ø`C

Vyxal Bot

@lyxal 248

lyxal

!!/run 248C

Vyxal Bot

12:20

@lyxal ø

Fmbalbuena

@lyxal How i do?

lyxal

make a bookmark with the url

javascript:(d=>{let%20e=d.createElement("script");e.src="https://abrudz.github.io/lb/vyxal.js";d.body.appendChild(e)})(document)

it should look something like this

(ignore my questionable choice of music lol)

Fmbalbuena

Uhhh google dont think is url

lyxal

are you on mobile or desktop?

Fmbalbuena

desktop google

lyxal

12:23

I'm running vivaldi which is basically chromium

you might have to bookmark a random page and edit the URL of the bookmark after it's made

Fmbalbuena

this

lyxal

no you need to set the bookmark URL to

javascript:(d=>{let%20e=d.createElement("script");e.src="https://abrudz.github.io/lb/vyxal.js";d.body.appendChild(e)})(document)

that is the url

all of it

Fmbalbuena

Now i't works

i need to type "javascript" without copy and paste

!!/run `ß∆ ʁ⟑ ⌈⌊ λ¬ `

Vyxal Bot

@Fmbalbuena Islands santa Disappointed and

Fmbalbuena

@lyxal i typed random words

that's how the dictionary works

Fmbalbuena

Is santa Disappointed by Islands?

probably :p

!!/run `₴ṁ is ¤„`

Vyxal Bot

@Fmbalbuena lyxal is crazy

lyxal

yeah, there's a bunch of 3 letter combinations in the dictionary

Fmbalbuena

@lyxal Is possible to convert base n to base n? (list)

lyxal

do you have an example in mind?

Fmbalbuena

12:45

no.

i can create in python but not vyxal

lyxal

I more mean whether or not you have an example of the data

lyxal

@Adám Welcome to the Vyxal chat room! Type !!/help for my list of commands, and !!/info for info about Vyxal!

Adám

@Fmbalbuena OK, I'm here. Now, why do I look like the Vyxal Bot?

Fmbalbuena

see?

Adám

Oh, you mean because I "auto" greet people in the APL Orchard?

Fmbalbuena

@Adám means

Adám

So the bot here remembers who it has seen in the past?

@Fmbalbuena "means"?

Fmbalbuena

18:28

if someome posts a command like !!/run, vyxal bot posts

and the @user deletes. the message of vyxal bot is deleted!

Adám

Oh, that's what you mean!

It just makes the transcript more sensible, imo.

And btw, iirc, it was my idea for the bot to remove its response in such a case.

So it makes more sense to say that the Vyxal bot is like me, than that I'm like the Vyxal bot.

Aaroneous Miller

18:49

Our bot took some inspiration from some other bots and things, so I'd agree with Adam there.

hyper-neutrino

VyxalBot is inspired by APLBot

why? because I wrote both of them

Aaroneous Miller

v

hyper-neutrino

and a lot of APLBot's design is inspired by how Adam chats

because it's the bot I made for his room so of course I designed it the way he wants and took all the feedback from him

and a lot of his ideas I found really good and just applied them to VyxalBot too lol

user

21:57

Hmm, perhaps if we ever figure out a way to upload minds to computers, Adám will be one of the first thanks to HN's work :P

Fmbalbuena

@lyxal I still have questions about Vyxal.

@Fmbalbuena I'll be able to answer them in around 5 minutes

Because I'm currently eat breakfast

Fmbalbuena

ok

i'll wait

@hyper-neutrino can i see vyxal bot source?

user

It's right here

lyxal

@Fmbalbuena righto lets begin

What questions do you have?

Fmbalbuena

23:16

@lyxal sorry for late reply, Is possible to sleep x seconds?

lyxal

23:27

Not directly, but you can using E and python

!!/run `import time;time.sleep(1)`E

Vyxal Bot

[@lyxal: 59613536]
0

STDERR:
'integer_contents'
Most recently popped arguments: ['import time;time.sleep(1)']
Final stack: []

user

lol

lyxal

Obviously, it won't work online

user

Oh, safe mode

lyxal

Correct

user

23:28

Can't we use pwntools' safe eval?

lyxal

It is

It's only literals and stuff

No function calls

user

Oh, isn't it safe for general evals?

lyxal

I don't know

But we're moving away from pwntools anyway

Fmbalbuena

@lyxal how to define x equals top of stack using python exec?

user

Ah

Fmbalbuena

23:32

Is that possible?

lyxal

@Fmbalbuena you don't need to

→x assign top of stack to x

Fmbalbuena

But... In python code?

Like

lyxal

`x = pop(stack)`E

Fmbalbuena

But you manipulated the variables of code

lyxal

So you'd want to prefix the variable name with VAR_

`VAR_x = pop(stack)`E

Fmbalbuena

23:36

Like `tokens = float("inf")`E

lyxal

That can work too

Although I'd avoid that in general

Fmbalbuena

How it works without erroring?

Ah bulid python self-interpreter

lyxal

Run it offline using the v2.4.1 release

user

No, Vyxal's written in Python, but it's disabled for the online interpreter for safety reasons

lyxal

github.com/Vyxal/Vyxal/releases/tag/v2.4.1

Fmbalbuena

23:38

But I use mobile chatroom. I use the desktop later.

lyxal

So that bad people can't run any python they want on the site, arbitrary exec is disabled online

user

Huh?

lyxal

I honestly don't know.

user

Oh crap I edited the release description

Fmbalbuena

@lyxal how you disable like exit() or int("a")?

user

23:40

That really shouldn't run on edits too lol

→ 1 message moved to Trash

lyxal

@Fmbalbuena the online transpile knows to use safe evaluation online

Because it has an internal flag that disables using pythons exec

I made a small edit too

Fmbalbuena

What small edit?

lyxal

→ 1 message moved to Trash

@Fmbalbuena just to the release notes

I have become Italian

hyper-neutrino

what

@hyper-neutrino v0.4.1 was released last year, but editing the release notes makes it seem like it was released today

user

Is there any way to distinguish between the webhooks for new releases and edits?

@lyxal i'll fix that later

lyxal

Cool cool

Anyhow, I gotta go for now

I'll be back in maybe an hour or so
