Piston uses Isolate which makes use of Linux namespaces, chroot, multiple unprivileged users, and cgroup for sandboxing and resource limiting. Code execution submissions on Piston shall not be aware of each other, shall not affect each other and shall not affect the underlying host system. This is ensured through multiple steps including:

• Disabling outgoing network interaction by default
• Capping max processes at 256 by default (resists :(){ :|: &}:;, while True: os.fork(), etc.)
• Capping max files at 2048 (resists various file based attacks)
• Cleaning up all temp space after each execution (resists out of drive space attacks)
• Running each submission as a different unprivileged user
• Running each submission with its own isolated Linux namespaces
• Capping runtime execution at 3 seconds by default (CPU-time and wall-time)
• Capping the peak memory that all the submission's processes can use
• Capping stdout to 1024 characters by default (resists yes/no bombs and runaway output)
• SIGKILLing misbehaving code

i love that i have to do this to get expr lead when working with unicode chars

what just happened 😭

this fixes uh

getting expr lead out of a location src

because before expr lead when calling foo(x); was giving weird results like (x); when i just wanted x out

[fleet cedar]

That makes it so it splits after that char instead of before, I guess

[valid jetty]

yeah

[fleet cedar]

You sure you don't want ctx.char_indices().nth(n).map_or(0, |x| x.0)?

[valid jetty]

uhhhhhh

[fleet cedar]

Using codepoint index is just silly though, why are you doing that

[valid jetty]

if i try to print an error on a line with japanese unicode symbols on it, it panics lol

using codepoints fixes it

[fleet cedar]

Uh

[valid jetty]

my old impl was just byte boundaries and was much tinier

pub fn get_expr_lead(&self) -> String {
    let ident = self.column - (self.ctx.len() - self.ctx.trim_start().len());

    let left = if ident >= self.length {
        ident - self.length
    } else {
        ident
    };

    self.ctx.trim_start().split_at(left).1.into()
}
``` but doesnt work

[fleet cedar]

Just be aware that byte offsets are objectively superior in every way

Does self.column do something that isn't byte offsets, or what

[valid jetty]

thats the case when working in ascii environments

[valid jetty]

lmao i guess

[valid jetty]

yes it tries to split on byte boundaries in some cases

https://cdn.discordapp.com/attachments/688124600269144162/1331420912871936107/image.png?ex=67e49c5a&is=67e34ada&hm=84fe869486bb4302f2278e225b8f528fc632bf175bb9de83c7bb0319242cae48&

or well it did

using code points fixes that

[fleet cedar]

That's because at some point, you are misinterpreting a codepoint offset as a byte offset

[formal belfry]

https://www.youtube.com/watch?v=UnbmwxYi18I

[valid jetty]

hm

[fleet cedar]

Codepoint offsets are worthless

Indexing by them is inefficient, and they aren't "meaningful" in any way that byte offsets aren't

[valid jetty]

the benefit of codepoint offsets is that i can iterate per unicode symbol which is useful in some cases

[fleet cedar]

Yes, iteration is useful

[lavish frigate]

does elle support emoji variable names

[fleet cedar]

It is unrelated to indexing

[valid jetty]

no i meant like

i can split a string containing unicode as if it was a string containing ascii, in a way

[fleet cedar]

Yep

It's just a sequence of bytes after all

[valid jetty]

well yeah ofc but like

in the string 「abc にゃ xyz」if i want to split into 「abc に」 and 「ゃ xyz」code points lets me treat the indexes as if all the characters were just ascii

its nicer to work with in a way

idk

ofc you could do the same with byte offsets

[fleet cedar]

You can't though

You can convert codepoint offsets to byte offsets and split at that

[valid jetty]

well

[lavish frigate]

is that a no...

another language that falls under the might of php

[valid jetty]

you can get each char's unicode code point length and increment the byte offset by that (instead of 1)

[lavish frigate]

lc.eval

<?php
$😀 = "fuck you";
echo $😀;

[visual shell]

​fuck you```

labsCore

[valid jetty]

no because it doesnt treat them as "identifiers" in the lexer

otherwise would be a yes

[fleet cedar]

Yes, converting codepoint offset to byte offset is O(n)

As opposed to converting byte offset to byte offset which is O(1)

[valid jetty]

i guess fair enough

[hoary sluice]

they could make the js ecosystem at least 10x better (still garbage tho) if they allowed trailing commas in json by default

[fleet cedar]

Noooo

Don't release an update to json, that'd be like python2->python3

[fleet cedar]

Sure it'd be objectively better, but it would ruin the ecosystem

[hoary sluice]

how

its fully backwards compatible

its not required

just less annoying

[fleet cedar]

How many hundred json parser implementations do you think there exist by now

[hoary sluice]

hundred thousands

[fleet cedar]

Yeah

[hoary sluice]

but surely theres an official json spec somewhere

they should allow trailing commas

[fleet cedar]

And how many of those do you think would update to support the new standard within 10 years

[hoary sluice]

seven

[fleet cedar]

Sounds about right

Which leaves 99993 json parsers that do not support the updated spec, meaning the updated spec is worthless

[hoary sluice]

then make it required

so the 99993 arent actually json parsers

and if someone says anything against trailing commas just kill them

[lavish frigate]

we should make json like js where we just constantly add to it but keep backwards compatibility in mind till we get incredibly ugly syntax

[fleet cedar]

Whichever linguistic tricks you choose to use, you are still splitting the ecosystem fatally

[hoary sluice]

maybe we need to switch off json

[fleet cedar]

This I can agree with though

[lavish frigate]

what about comments

[hoary sluice]

adding support for trailing commas is literally just deleting 1 line

[hoary sluice]

i dont comment anythin anyways

but having to retroactively add commas is annoying

[fleet cedar]

1 line in 4 million programs, half of which will never receive an update ever again

[lavish frigate]

with how much people configure in json files now we need comments imo

actually

can we ditch json please

[fleet cedar]

Json is, fundamentally, a data serialization format

Using it for configuration is foolish

[hoary sluice]

can we use rust struct for everything

[fleet cedar]

That's not a serialization format

Nor configuration

[lavish frigate]

toml & yaml & xml & ucl & ini:
"i cant wait for json to fall so i can rise from the ashes"

[fleet cedar]

Xml has had its turn, it's long dead

Tf is ucl

[lavish frigate]

its still used by

uh

html

and

microsoft...

[fleet cedar]

Html isn't xml though

[hoary sluice]

pub struct KeybindConfig {
  pub altK: Action,
}

let conf = KeybindConfig {
  altK: Action.whatever(),
}

here u go

config using rust structs

[fleet cedar]

But yeah, there exist some programs that do use xml (usually inside zip files)

[lavish frigate]

html is xml with a funny spec

and you cant tell me otherwise

[hoary sluice]

yea so its dead

[lavish frigate]

do you not like winui3?!?!?!

[hoary sluice]

html is just xml but something about it makes it incompatible

[fleet cedar]

It has superficial similarities in which tokens are used in the syntax

[hoary sluice]

i hate anything that is related to microsoft

[valid jetty]

theyre a "json subset parser"

[fleet cedar]

They are parsers for application/json

[valid jetty]

also isnt there jsonc which allows comments and trailing commas

[lavish frigate]

like the only thing that makes them incompatible is that html has some funny tags that you dont close (<br>, <img>, etc.)

[fleet cedar]

If you want to make a different format, give it a different name

[hoary sluice]

microsoft should do what microstrategy did
give up on software and buy a whole bunch of bitcoin, then take out debt against that bitcoin to buy more bitcoin

[valid jetty]

yes, jsonc

[lavish frigate]

json2

[hoary sluice]

jsonc makes it sound like its related to C

[valid jetty]

lol no json + comments is what the c stands for

[hoary sluice]

ik

dont call it json cause its no longer javascript object notation

[valid jetty]

@hoary sluice look at this very real code

static bool CheckNumbersUsedAreAllInNumbersAllowed(List<int> NumbersAllowed, List<string> UserInputInRPN, int MaxNumber)
{
    List<int> Temp = new List<int>();
    foreach (int Item in NumbersAllowed)
    {
        Temp.Add(Item);
    }
    foreach (string Item in UserInputInRPN)
    {
        if (CheckValidNumber(Item, MaxNumber))
        {
            if (Temp.Contains(Convert.ToInt32(Item)))
            {
                Temp.Remove(Convert.ToInt32(Item));
            }
            else
            {
                return false;
            }
        }
    }
    return true;
}
``` that the year above me is given as part of their exam for CS

i reimplemented

static bool CheckNumbersUsedAreAllInNumbersAllowed(HashSet<int> numbersAllowed, List<string> userInputInRPN, int maxNumber) {
    foreach (string item in userInputInRPN) {
        if (CheckValidNumber(item, maxNumber) && !numbersAllowed.Remove(Convert.ToInt32(item))) return false;
    }

    return true;
}
``` lol

[hoary sluice]

call it balls (braced all loveable lizard system)

[fleet cedar]

And all the other auto-closing rules such as for <p> and <td>, and that attributes can be unquoted, and that attributes don't need to have a value at all, and that there's no namespaces, and whatever the fuck DTDs are

[lavish frigate]

javascript objects allow for trailing commas so javascript object notation should too

[fleet cedar]

Javascript objects allow function() {} expressions, should json?

[lavish frigate]

auto-closing rules? you mean the thing that nobody needs anymore because people decades ago were too stupid to make vscode to tell them to close their tags?

:3

[lavish frigate]

of course

[fleet cedar]

I mean the things that are clearly specified in the spec

[valid jetty]

i write my code in notepad

[hoary sluice]

from the function signature what it should do is

return numbersUsed.all { it in numbersAllowed }

except it doesnt and it still has a really long name

the only justification for a really long name is if its descriptive of the function

[valid jetty]

its not lol

[lavish frigate]

like idk everything you described seems like stuff that was added cuz people were too stupid to write correct html nobody does that anymore

except like

attributes without values

[valid jetty]

the code is just so

omg

[fleet cedar]

Sure?

But the spec says so

[lavish frigate]

the spec is stupid

im going back in time to fix it

[hoary sluice]

just use rsx!

[fleet cedar]

Nobody cared for xhtml when it was invented 25 years ago

I don't think you're gonna have better luck now

[valid jetty]

@hoary sluice look at this one

[hoary sluice]

are you writing an compiler in cs

[lavish frigate]

yea vscode still didnt exist then to automate writing the boilerplate for that

! my beloved

[valid jetty]

no i would never write this code in my life

[hoary sluice]

if i ever have to write html again im probably gonna write rsx and then convert it to html

[valid jetty]

this is code that the year above me was given from the exam board as part of the CS exam

[lavish frigate]

c# is an insane language for insane people

[fleet cedar]

If html was to be redesigned in this age it probably wouldn't be text at all

[lavish frigate]

which one of you ordered sql inside their programming language

[valid jetty]

they have this code now and they have to answer questions on it and fix parts of it and add to it, during the exam

[hoary sluice]

were they told to refactor it or what was the task

[lavish frigate]

why would it not be text

[valid jetty]

[hoary sluice]

me when im at the based competition and my opponent is std::panic!("Chloe")

[fleet cedar]

Binary can be parsed faster

[valid jetty]

std::panic!("i left the cake in the oven for too long!");

[lavish frigate]

yeah but binary is also less accessible

[fleet cedar]

So what?

[hoary sluice]

yea why is http plain text

[fleet cedar]

Who writes html by hand these days

[hoary sluice]

who thought that was ever a good idea

[lavish frigate]

most websites still run on jquery 😭 like idk accessibility is what made the web the web in the first place

[valid jetty]

but people arent writing performance critical software theyre writing todo lists and ai chat apps lol

[lavish frigate]

you cant just go "it would be in binary cuz its better!" it would fail

[fleet cedar]

It's not like html would cease to exist, just like http still exists even though all the big ones use http2

[lavish frigate]

people would make an accessible format and people would put their shit on there

id be all for a binary format if it was optional but google would want to support it so there is no point

how many people started programming from html?

[valid jetty]

i mean if you want to send binary data nowadays you use protobuf right

[fleet cedar]

Zero because html is not programming

[valid jetty]

bold claim lol

may not be programming in the traditional sense but its still "declarative scripting" in a way

[lavish frigate]

if i was implying that html was a programming language i wouldve used with not from, young devs started with html then went onto real programming languages from there

[valid jetty]

yeah ^

[fleet cedar]

That's fair I guess

[valid jetty]

even i started in python and html lol

but that was boring tbf

[hoary sluice]

arguing that html isnt a programming language is stupid its all just semantics

[fleet cedar]

I started with minecraft redstone, which isn't a programming language either

[hoary sluice]

like yea markdown isnt a programming language but its also not the main component of websites

[lavish frigate]

if i didnt get curious making stupid html sites in class i would probably not have started with programming

[hoary sluice]

who says it isnt

[valid jetty]

erm actually 🤓 👆 html is a markup language not a programming language

[hoary sluice]

someone made a bitcoin miner with minecraft redstone id argue thats a programming language

[hoary sluice]

erm actually smb

[valid jetty]

have you seen mattbatwings videos, redstone is turing complete

[shrewd canopy]

Not everything wants to receive protobuf, e.g Minecraft servers
But i think I prefer making a byte array, write stuff there, and send it

[hoary sluice]

redstone is literally just electrical engineering but in java

branch elimination, branch prediction hinting, memory alignment are great optimisation techniques

[valid jetty]

@hoary sluice @deep mulch @placid cape look at this delightful code i have to write to get branched dispatch working for both chars and strings

local fn __internal_throw_invalid_needle(ElleMeta meta, ElleMeta caller_meta, ...args) {
    io::cprintf(
        "[%s:%d:%d] ERROR: Expected a second argument of type 'string' or 'char'.\n",
        caller_meta.file, caller_meta.line, caller_meta.column
    );

    for i := 0; i < meta.arity; i += 1 {
        if meta.types[i] == "string" {
            io::cprintf("%s", args.yield(string));
        }
    }

    libc::abort();
}

fn string::contains(ElleMeta meta, string self, ...args) -> bool {
    if meta.arity != 2 {
        __internal_throw_invalid_needle(meta, "The needle argument was not provided.\n");
    }

    if meta.types[1] != "char" && meta.types[1] != "string" {
        __internal_throw_invalid_needle(meta, "Got a value of type ", meta.types[1], " instead.\n");
    }

    needle := nil;

    if meta.types[1] == "char" {
        char temp[2];
        temp[0] = args.yield(char);
        temp[1] = nil;
        needle = temp;
    } else {
        needle = args.yield(string);
    }

    return (void *)strstr(self, needle) != nil;
}

[hoary sluice]

how have i never heard of this

[valid jetty]

(spoiler its NOT this hard when working in user code, this is the stdlib so i dont have access to methods like $panic, string::as_string, string::format, and more)

[deep mulch]

Rosie is a genius

[hoary sluice]

why do you not have access to stdlib methods in stdlib

[valid jetty]

because string::format uses string::as_string which does dispatch for all the primitive types

how do you check what type was passed in? the contains method.

and also $panic uses string::format

with the stdlib methods its about this hard to get the same behavior lol

local fn __internal_throw_invalid_needle(string message, ElleMeta caller_meta) {
    $panic("Expected a second argument of type 'string' or 'char'.\n{}", message);
}

fn string::contains(ElleMeta meta, string self, ...args) -> bool {
    if meta.arity != 2 {
        __internal_throw_invalid_needle("The needle argument was not provided.\n", meta);
    }

    if meta.types[1] != "char" && meta.types[1] != "string" {
        __internal_throw_invalid_needle("Got a value of type {} instead.\n".format(meta.types[1]), meta);
    }

    needle := meta.types[1] == "char"
        ? string::as_string(args.yield(char));
        : args.yield(string);

    return (void *)strstr(self, needle) != nil;
}

[deep mulch]

Rosie I am terrified

[valid jetty]

the reason i wrote the whole dispatch thing is because i couldnt do "01".contains(x) where x is a char

oh yeah another cursed thing i wrote

use std/prelude;

fn main() {
    while true {
        bin := Array::from_string(io::input("Enter a binary string: "));

        if !bin.every(fn(char x) "01".contains(x)) {
            $eprintf("Invalid string: {}", bin);
            continue;
        }

        mult := math::pow(2, bin.len());
        res := 0;

        for c in bin {
            c == '1' && (res += mult /= 2);
        }

        $dbg(res);
    }
}

binary to denary

this is my favourite elle expression so far c == '1' && (res += mult /= 2);

[deep mulch]

AAAAA

[valid jetty]

i wouldve loved to define bin in the if statement BUt @placid cape told me not to do that because thats what python does xd

[hoary sluice]

why are u cheating on ur cat in ur pfp

[deep mulch]

idk

[valid jetty]

@royal nymph do you love c == '1' && (res += mult /= 2);

uh oh

@ornate quiver do you think a ColorPickerState would make sense to switch to or leave as is

[ornate quiver]

I don't see any reason how a dedicated state would improve anything

everything is already contained in Color

[deep mulch]

well

the hsv technically isnt

[ornate quiver]

oh because converting between RGB and HSV is lossy?

[deep mulch]

yes

[ornate quiver]

i guess in that case state would be good

[deep mulch]

if R == G == B then hue and saturation is lost

[ornate quiver]

better than manually specifying 3 parameters

[deep mulch]

idk if itll help much im thinking

[ornate quiver]

I think it would be good in that case

[deep mulch]

i pay you to do

i might request for Color class to better support hsv somehow

[ornate quiver]

I would do

[frosty obsidian]

technically the color class is a packed value wrapper

[deep mulch]

yes

value class

[frosty obsidian]

its not guaranteed to be rgb

compose devs are good and made it support different color spaces

[ornate quiver]

really

[deep mulch]

wrong

[frosty obsidian]

yeah

[deep mulch]

HSV and RGB are the same color space

[frosty obsidian]

it supports rgb, srgb, xyz, and lab

well doesnt he not use gh xd

[royal nymph]

yeah obv lol

just saying the unverified is cause I signed it (with my signature) but he doesn't have any uploaded

[wheat kernel]

gotta keep using mailing lists

ohh i thought it meant he has the vigilant mode thing on

[royal nymph]

he either doesn't sign or github mirror strips it

[ornate quiver]

where was the fake torvalds commit

today i discovered rlwrap

[placid cape]

whats that

[valid jetty]

its so cool it lets you basically get a readline interface on any cli without needing to implement it in the src

by readline i mean like in a repl

where you can use arrow keys to look at previous commands, uhhh do reverse search, jump around the current line

stuff like that

[placid cape]

okay interesting

lmao internal serevr error

reddit down

[valid jetty]

its slightly broken with that preceding character but that doesnt show up when you send it to the repl

idk if thats an rlwrap issue or an issue in elle maybe im not flushing the stream or something

[dawn ledge]

iirc nushell also published a package ni the vein of readline

https://github.com/nushell/reedline

[dawn ledge]

yeah so this issue is i assume rlwrap is not handing the keys it reads and directly sends it to stdout

its similar to how sh behaves

oh

thanks thats epic didn't know I could do that hehe

[lavish frigate]

the api probably just does exactly that 😭

[eternal wigeon]

you know your javascript

[hoary sluice]

you didnt know your computer had a clock?

[eternal wigeon]

is there tho..

[dawn ledge]

needs 500 micro dependencies

[eternal wigeon]

lmao

[royal nymph]

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/DateTimeFormat#using_options

[hoary sluice]

depends on nextjs

[eternal wigeon]

wym this isn't a perfectly optimized workflow?

get time from api

[still jolt]

once you receive the time from the api it'll already be out of date, kinda ironic

[eternal wigeon]

lol

[dawn ledge]

what in the chatgpt wrapper is this

[eternal wigeon]

it's a very awesome tool im building a huge chatbot that also spies the responses and extracts the relevant info

[hoary sluice]

so a chatgpt wrapper

[eternal wigeon]

i wrote that like a r*tard

no, it's a bot made in typebot

typebot alr has all ai integrations

[hoary sluice]

just admit its a chatgpt wrapper

[eternal wigeon]

lmfao I'm so weird I shouldn't have written it like this

[eternal wigeon]

no, chatgpt isnt allowed to respond to my end user

its groq coder btw

it generates a json with the relevant data if it finds it

ai is fucking awesome

[royal nymph]

[eternal wigeon]

and getting date from an external api made the conversation start 2 second slower which was bad

lol

How can i access the webpackChunkdiscord_app array from the Discord/app.../discord_desktop_core/core.asar unpakced .js files ? (its not in the window obj too). Trying to mod the official client so i can see experiments by default

[dawn ledge]

look at vencord

[royal nymph]

do you understand different electron processes

main, preload, renderer

[proud kayak]

sadly never done anything with electron before, just random pure js stuff

[royal nymph]

well then learn basic electron before trying to mod (or just use vencord)

there are three processes:
main: nodejs host process
renderer: sandboxed browser process
preload: bridges the two

webpackChunkdiscord_app is inside the renderer process

core.asar is main process

they are separate isolated processes and you need to use IPC to communicate

main process can't access webpackChunkdiscord_app

[proud kayak]

oh damn, will look into it, tysm

[royal nymph]

main process is what starts the browser window and has native code

preload runs pre-load of the browser (duh) and allows you to register ipc listeners and inject code into the browser

then browser loads and it's literally just chromium

[dawn ledge]

you dont necessarily have to inject into the main process js
you can also mitm the client js ^:)

[jade stone]

what format is electrons app.asar

all file tells me is that it's data

[royal nymph]

the way Vencord patches discord (very simplified) is:

1. We replace discord's main entry point with our own
2. Our main patches Electron's BrowserWindow class (what you use to create a new browser window)
3. Whenever Discord creates a browser window we specify our own preload script on it instead of Discord's
4. Then our main script loads Discord's main script
5. Discord now creates the BrowserWindow
6. Electron runs Vencord's preload script now, which injects Vencord's renderer script and then loads Discord's original preload
7. Vencord's renderer script is what contains 99.9% of Vencord's code and that then patches webpack

[royal nymph]

It's an original archive format

[jade stone]

love

[royal nymph]

very similar to tarball but custom

[dawn ledge]

its just [MAGIC][JSON for FILE STRUCTURE and size][...concated files]

they have documented it

[royal nymph]

install @electron/asar from npm

[dawn ledge]

its open

yeah

[royal nymph]

then asar e app.asar to unpack and asar p app to pack

[jade stone]

ofc its open, isnt all of electron opne?

[royal nymph]

it's an incredibly simple format

you can open it with a text editor

[dawn ledge]

its so simple i wrote a rust crate for it in one day (incomplete) and published it like a stupid idiot

[dawn ledge]

i wouldnt recommend it tho
reading concated files aint the best experience

[royal nymph]

the header is just a JSON

and then contents of all files uncompressed

GPL jumpscare

[dawn ledge]

some times i wish i could delete crates from crates.io

[lavish frigate]

i just opened this project im gonna be sick 🤢

[fleet cedar]

They didn't commit their linter rules?

[lavish frigate]

no you see there are layers of problems here the first one is that i opened a file and i get linter warnings (they have eslint installed and configured correctly)

[fleet cedar]

If you mean "I don't like their code style", that's a different thing

[lavish frigate]

the next layer is that they are not following the company default code styling

[ionic lake]

you should just configure vscode to not show style lints but they still will be fixed

[lavish frigate]

it was made by backend devs

[lavish frigate]

nah im going through everything and fixing the code styling

[austere idol]

rate this code plz:

use std::env;
use std::fs;

fn main() -> Result<(), Box<dyn std::error::Error>>
{
    let args: Vec<String> = env::args().collect();

    if args.len() < 2 {
        panic!("specify file with links");
    }

    let data: String = fs::read_to_string(&args[1])?;

    for link in data.split("\n") {
        if link == "" { continue; }
        let link_s = link.to_string();

        if !fs::exists(&link_s[link_s.rfind('/').unwrap() + 1..])? {
            println!("{}", link);
        }
    }

    Ok(())
}

[formal belfry]

the first one is that i opened a file and i get linter warnings

first time?

[ornate quiver]

collecting args into vec is unnecessary
im fairly certain there's a better function to read lines that also handles CRLF

[lavish frigate]

yes, .lines() https://doc.rust-lang.org/std/io/trait.BufRead.html#method.lines

[fleet cedar]

Or str.lines()

BufRead.lines() has the drawback that it allocates a new String every time

str.lines() on the other hand requires the whole String to be read into memory upfront

Which doesn't work well with streaming input like stdin

[lavish frigate]

tbh i just took the first .lines result on google 😭

[fleet cedar]

You can do BufRead.read_line() in a loop to avoid reallocation, though it's a bit of a slog

Instead of &link_s[link_s.rfind('/').unwrap() + 1..], use .rsplit_once('/')

And what's with the let link_s = link.to_string();, it looks completely unnecessary

Both the to_string'ing, and that you give it a different name

[lavish frigate]

Oh thats co- WHAT????

    let data: String = fs::read_to_string(&args[1])?;
    for link in data.lines() {
        let (_, fname) = link.rsplit_once('/').unwrap();
        if !fs::exists(&fname)? {
            println!("{}", link);

vibe coding is yet another fad used by techfluencers to sell you their course, it will die in a few months hopefully

[blazing haven]

had to look that up

read the first sentence

Vibe coding is an AI-dependent programming technique

automatically disqualified

[ionic lake]

vibe coding is when you leave an llm entirely to do the programming for you and you just manage and prompt the project

[fleet cedar]

It's when you want to be a PM without hiring anyone

[blazing haven]

@deep mulch microsoft is going to make me go insane

they use $(CC) in their nmakefiles

but use normal link

[deep mulch]

whats that mean

[valid jetty]

why is that bad

other than the fact they hardcode flags which wouldn’t work on non-windows compilers

[royal nymph]

u cant override linker

[valid jetty]

how would hardcoding msvc make it so you can override it?

[royal nymph]

$(LINKER)

[valid jetty]

can’t you also just use -fuse-ld=foobarbaz

or is that not a thing on windows

[royal nymph]

but ig if the flags are not universal it doesnt make sense anyway

you can probably do smth like

@hoary sluice can’t wait to vibe code aoc next year !

@fleet cedar @valid jetty how do i block whisper_rs stdout, i dont think i can configure the library to not print anything

[fleet cedar]

If it uses println then you can't

[valid jetty]

^

#[no-std]

[fleet cedar]

Send a pr I guess

[hoary sluice]

solution: dont use whisper

@valid jetty imma apply to this https://career.cloudflight.io/jobs/2541992-site-reliability-engineer-m-f-x

i did an internship with them last year

the company is pretty cool but i had to use js so i hated it

[valid jetty]

but this isn’t a vibe coding job

do you really want to do real engineering smh

[lavish frigate]

the obvious solution is to send a pr to your terminal adding functionality to block outputting lines based on regex

[jade stone]

Nah, I'm just going to apply a git patch

Or just pipe through grep -v

Though that'll run into issues with isatty detection for coloring

the point is that i can do that question easily but its funny to write an unreadable linq 1 liner for it instead

i can only imagine like some kind of package repositories being affected

@valid jetty our measurement systems teacher said we can do anything we want in the next lab excercise, should i make a digital filter calculator in haskell

[deep mulch]

I don't like java

omg should i make it in elle

im gonna make it in elle

[deep mulch]

yes

[hoary sluice]

@valid jetty make an elle lsp and formatter before monday

[deep mulch]

@valid jetty make Elle FFT library

[hoary sluice]

i will actually do that

[hoary sluice]

@valid jetty why did u add so many deps

[valid jetty]

i didnt

i added chrono to build deps

[deep mulch]

Elle will take 5 hours to build and need 32 GB of ram and 200 GB of storage

[hoary sluice]

how do i add something to the elle stdlib

where are all the external fns implemented

[valid jetty]

in std/runtime

[hoary sluice]

i found it

[deep mulch]

I will make Elle better

[hoary sluice]

so the ones in std/ are just header files basically?

[valid jetty]

to add something, make a file in std/runtime, import it in std/runtime/registry.le then make the relevant std/ header

[valid jetty]

yes

[deep mulch]

horror

[hoary sluice]

there will be an fft question in advent of code and you will get #1/#1 with my elle fft lib

[valid jetty]

oh dont forget to make after to reinstall the runtime

[valid jetty]

:3

[deep mulch]

@valid jetty you will be used as crab bait

[valid jetty]

@hoary sluice keep in mind if you want your functions to be generic you need to put their body in std/ directly

you cant have generic functions in the runtime

[hoary sluice]

why not

[valid jetty]

because the runtime builds into an object file then a static lib

you cant have non-monomorphized functions in an object file

[hoary sluice]

ok

[deep mulch]

what

[hoary sluice]

do u use an lsp

[deep mulch]

that's not a real word

[valid jetty]

cmd-k m, select c++

[deep mulch]

@valid jetty hii

[valid jetty]

hii

also @hoary sluice on real terms they would never put fft in aoc thats too complicated for the average developer to figure out

[hoary sluice]

uhh

[valid jetty]

i know i would struggle

or well

[hoary sluice]

your face when the 2019 day 16

[valid jetty]

oh

[hoary sluice]

(its not actual fft)

but its in the spirit of fft

[valid jetty]

oh fun

[deep mulch]

@valid jetty @valid jetty make me smart

[valid jetty]

yeah i didnt expect a full on fft

[valid jetty]

become autistic or something

[deep mulch]

I think I am

[valid jetty]

get hyperfixated on programming then

[deep mulch]

I don't have hyper fixation

I just have anxiety

[valid jetty]

ouhhh

sad

[hoary sluice]

its not actual fft like you cant use fft lib for it but it probably doesnt hurt to know how fft works

[valid jetty]

i mean fft isnt that hard to just call a function lol

[deep mulch]

@hoary sluice 🦅ly

[valid jetty]

but the theory is the hard part

[hoary sluice]

well yea thats why he changed it

its still a sum of products over a list of numbers which is what dft is

just with a different formula without complex numbers

[valid jetty]

yeah

oh btw i found a simpler way to do that string thing from earlier

fn string::contains(ElleMeta meta, string self, ...args) -> bool {
    if meta.arity != 2 {
        __internal_throw_invalid_needle(meta, "The needle argument was not provided.\n");
    }

    if meta.types[1] != "char" && meta.types[1] != "string" {
        __internal_throw_invalid_needle(meta, "Got a value of type ", meta.types[1], " instead.\n");
    }

    needle := meta.types[1] == "char"
        ? #[args.yield(char), '\0']
        : args.yield(string);

    return (void *)strstr(self, needle) != nil;
}

instead of a buffer thing i can just use a static array lol

[hoary sluice]

i dont think i read that

[valid jetty]

you did i think

[hoary sluice]

i read the align

[valid jetty]

yeah hi

[hoary sluice]

oh

i guess i did

[valid jetty]

the improvement is

needle := nil;

if meta.types[1] == "char" {
    char temp[2];
    temp[0] = args.yield(char);
    temp[1] = nil;
    needle = temp;
} else {
    needle = args.yield(string);
}

needle := meta.types[1] == "char"
    ? #[args.yield(char), '\0']
    : args.yield(string);

[hoary sluice]

needle := nil

why do you have nil

[valid jetty]

nil is just a void* typed constant to 0

[hoary sluice]

yea why do null pointers exist

[valid jetty]

because elle isnt memory safe??

[deep mulch]

Elle will have undefined as well

and NaN

[hoary sluice]

elle will have ===

[deep mulch]

Elle will have implicit string concatenation like js

[valid jetty]

and anyway thats a benefit here because you can write this code

lexer := Lexer::new(args[0]);
tokens := [Token *;];

while current := lexer.next_token() {
    tokens.push(current);
}
``` and this loop exits when `lexer.next_token()` returns `nil` (a null pointer)

[deep mulch]

;]; looks so wrong

[valid jetty]

lmao

true but idk another place to put it

[deep mulch]

@valid jetty is silly

[valid jetty]

no i explicitly made it so you CANT do that

[deep mulch]

@valid jetty

[valid jetty]

you have to either ```rs
x := "hi";
x <>= string::as_string(1);

OR
```rs
x := "hi";
x <>= "{}".format(1);

the behavior internally differs slightly but you get the same string in the end

[deep mulch]

oh my god

<>= 😭

fish operator

[valid jetty]

lmao yeah !!!

<> is the concat operator

[deep mulch]

why not just +=

[valid jetty]

$assert("x" <> "y" == "xy")

[valid jetty]

you forget elle is also a low level language

strings are char*

you can use + to offset a string

[deep mulch]

guuuhhh

[valid jetty]

i need to add function overloading at some point so you can make the same function return different things

like i want to make it so when you index by a number you get T but when you index by a range you get T[]

currently you can only index by a number

because even though you can do dispatch to take in both a number and range, you cant return T or T[]

[hoary sluice]

why does it point to a _- thingy

how do i link the stdlib

[valid jetty]

i have to fix that actually thats because it uses the wrong location printer for those errors

[valid jetty]

you dont its automatically linked at comptime

you can do --nostd to unlink it

uh hold on i may have to install qbe

[valid jetty]

that too

[hoary sluice]

lmao

[valid jetty]

make clean after installing qbe

then make -B

to install qbe just uhhh, clone the qbe git, cd into it, run make, then move it to somewhere in your $PATH

[hoary sluice]

or just pacman -S qbe lol

[valid jetty]

is that latest git tree tho

[hoary sluice]

idk but it works

[valid jetty]

does the runtime compile

[hoary sluice]

its probably pretty recent

if it stops working i can do yay -S qbe-git

[valid jetty]

oh

fun
