Q: AoCG2021 Day 23: Finding the best seat

Part of Advent of Code Golf 2021 event. See the linked meta post for details. Related to AoC2020 Day 11, Part 2. You enter the waiting area for a ferry, and you see a bunch of people sitting at a bunch of seats. The seats form a grid like this (. is a floor, L is an empty seat and # is an occupi...

Probably the trigger here is "best"

Ah yes "Challenge", very descriptive

lyxal

mmm yes I have a "bytes" long answer in Language to that challenge

Redwolf Programs

I'm considering answering in language

But it could very well take an amount of time

hyper-neutrino

I think you could save some bytes by golfing

caird coinheringaahing

Potentially, you might have to use a few different builtins

I just got IRL spam from a college I really want to go to!

Spam is fun when you want to be spammed

And not one of the 20 schools that've sent me email spam in the last two days

That's not even an exaggeration

caird coinheringaahing

@RedwolfPrograms Tell them that if they let you in, you'll improve their email spam so that its less obviously spam :P

Redwolf Programs

But this wasn't email spam! It was actual mail spam!

It means they're willing to spend a whole 2¢ to send it to me

caird coinheringaahing

Oh, that's so much worse :/

hyper-neutrino

who even uses snail mail anymore smh

Redwolf Programs

@cairdcoinheringaahing Nah, I only get mail spam from actually good colleges for some reason

So it's fun to collect it

caird coinheringaahing

01:38

Personally, if I want to "mail" something to someone, I scrunch it up into a ball and throw it in the vague direction of their house and hope

Redwolf Programs

I mean it's kinda cool that you can just write someone's address on a piece of paper, put a sticker on it, drop it in a box, and it'll show up at their mailbox in like a week

user

Imagine not immediately throwing away spam from good colleges because you know you won't get in :P

@RedwolfPrograms ~~Very convenient for spreading anthrax~~

Cool, and I was afraid no one would come over for Christmas! :P

Do you think FBI agents prefer chocolate cookies or brownies?

~~You can put anthrax in both equally well~~

Imagine if COVID-19 was like DVD-R and DVD+R, where COVID+19 did the same thing but you had to buy two immune systems since they're technically incompatable because sony made one of them

Inspired by the most recent xkcd tooltip

I find it oddly fun to poke around in the inner workings of online interpreters by running console.log(require('fs').readdirSync("."));

You can make a cheating quine in TIO with console.log(require("fs").readFileSync(".code.tio","utf-8"));

pxeger

02:47

@RedwolfPrograms use Zsh, and just do ls :)

Redwolf Programs

Well, I had to do that when I was poking around in ATO :p

pxeger

there's nothing there, muahaha

it's all ~~hidden~~ one directory up

ato.pxeger.com/run?1=m724qjhjwYKlpSVpuhYrc4oVdHMSFfT0IHyoMEwaAA

Redwolf Programs

CMQ: What are your must-have languages for an online interpreter? Preferably less common ones; stuff like JS, Python, Jelly, Ruby, Haskell, etc. are obvious choices

pxeger

Zsh 5.8

Python 3.10

Ruby 3.0

Node 17

basically I want everything to always be very up to date

Redwolf Programs

Oh, that's a good one

I wonder if things like nvm exist for other languages...that could be an easy way to automate keeping them up to date

pxeger

02:55

rvm for ruby (which I think nvm was based on, actually)

I think there's one for Python but noone uses it because Python's just that good and has very few breaking changes

Python's also very easy to build from source

user

@RedwolfPrograms Java, C, C++ are very commonly used (unless you're talking specifically for golfing, and even then they're pretty common)

I like Husk and Scala, so those would be nice to have too

Oh nvm you want less common ones

Redwolf Programs

Those are good too though, Scala's one I wouldn't have thought of

user

Having both Scala 2 and 3, on all three platforms (JVM, JS, native) would be pretty good

Redwolf Programs

How different are the platforms?

user

Then the various APLs

@RedwolfPrograms Not super different, honestly, although Scala.JS allows some drawing stuff, I guess

Redwolf Programs

03:04

Well that's not super useful in a text-based online interpreter lol

user

Ah ok

There are big differences between Scala 2 and 3 though, it'd be great if you could support both once you have the time

Redwolf Programs

And the good thing about RTO's model is that even if I ignore you and don't add any Scalas at all, you can just add them yourself :p

user

Wait really? :o

Redwolf Programs

RTO's being designed to be updatable, even in the long-term abscence of its maintainers

And people can add their own esolangs at any time

user

How would that work? People have access to write to your server?

Redwolf Programs

03:08

(They have to go through some approval stuff first of course)

@user There'd be a few ways you can do it, docker images being one

Or, if the language your interpreter's written in is already installed, you can have that language's image call your interpreter

E.g., you could write brainfuck.py, and then just submit it and whenever somebody runs brainfuck code it'd spin up a python instance and run brainfuck.py in it

Everything is, of course, safely sandboxed, so a malicious language wouldn't be able to do much, but there's going to be an approval process

user

Wouldn't someone be needed to approve PRs, though?

Also, time to go PR a modified version of ATO's Scala image(s) :)

Redwolf Programs

Not PRs, it's uploaded through the site

user

Oh

ATaco

03:26

@RedwolfPrograms Lua. Can't live without it.

lyxal

@RedwolfPrograms what if it's too big to upload?

Redwolf Programs

Umm...is there a specific languages you have in mind?

lyxal

Probably vyxal

Redwolf Programs

How big is it?

lyxal

Last time I checked its 30mb maybe

Probably mote

*more

Redwolf Programs

03:37

Those are rookie numbers

The Node image is over a gigabyte

(It comes with a full debian install)

lyxal

But I more mean generally what if there is a language someone wants to add but can't upload for some reason

Redwolf Programs

It's hard to answer that, there's just too many unknowns

lyxal

Would there be a way to just link the github/gitlab/whatever repo and have that cloned locally?

Redwolf Programs

Possibly, that's a good idea

lyxal

@RedwolfPrograms example: someone can't download the language files needed because they don't have enough space on their own computer or they don't want to have the files locally

Also, will there be options to have multiple language versions at once?

ATaco

03:40

I miss TIO. I hope Dennis is doing okay.

10

Redwolf Programs

@lyxal Yes, definitely

I'm adding a feature where every language can have variants, such as different versions, or CPython vs. PyPy type stuff

ATaco

Is the intention only major languages, or would esoteric/golf languages be within scope?

Redwolf Programs

All languages will be within scope

lyxal

@RedwolfPrograms Would there be a limit on how many subversions allowed?

Redwolf Programs

Possibly, but if so, it'll be a large number

lyxal

03:42

Because I know python 3 has quite a few fun little subversions

Redwolf Programs

For common languages like Python or Vyxal, especially if a small linux distro like Alpine is used as the base, I'd probably be fine with close to a hundred

lyxal

Oh

Well dang

Ooh I have a feature suggestion

People can also add pre-loaded examples for languages

Basically the "Hello world" button on TIO but customisable

Redwolf Programs

Ooh, that's a great idea

I was also planning on having an "info" tab along with "run" and "post", for docs and explanations of examples

lyxal

How about also on screen keyboards for sbcs languages

Redwolf Programs

That could also be a good idea, although it probably won't be in the initial release

lyxal

03:47

Also, customisable themes stored locally with cookies or something

That would be cool

Redwolf Programs

Eh, seems like anyone who cares enough to customize the theme would already have a userstyles extension

lyxal

Not necessarily

It'd be for people who aren't good with css

Like me

Maybe I'm missing something obvious, but... how does hyper's CodeReview.SE answer about Vyxal have syntax highlighting on the code blocks? There doesn't seem to be any language specification. Does CR try to guess a language automatically?

lyxal

I thought language guessing was a standard part of SE networks

DLosc

IDK, I mostly hang out here and on non-programming stacks. Do our code blocks try to guess a language? I've always thought you had to specify one explicitly if you wanted highlighting.

lyxal

That's the thing though... TIO always inserts the highlighting scheme at the top of languages in applicable answers

Someone would have to experiment

BRB gonna go commit science

Looks like it doesn't guess

DLosc

I'm pretty sure I remember somebody editing one of my old (pre-TIO) Python answers just to add syntax highlighting

Bubbler

@DLosc The syntax highlighting framework tries to guess the language (from the list of known languages for it) from the given block of code. To entirely disable syntax highlighting, you need to insert a comment line  or something

or specify none as the language in the triple-backtick block

lyxal

05:10

But it doesn't seem to do that here

E.g codegolf.stackexchange.com/a/205046/78850

I edited out the default tio highlight rule and now it doesn't have any colour

Bubbler

Idk the specifics, you could ask a meta Q about it

DLosc

C(R)MQ: How many esolangs have tags on Code Review? I know I've seen questions there in BF, Lolcode, and Vyxal

uniform statistically independent?

if you just specify that they should be chosen uniformly that's fine

@UnrelatedString so basically apply at certain indices

Unrelated String

ye

¦ is apply at given indices but it does so by applying to the entire list then masking the before and after together

hyper-neutrino

yeah... like wtf is this lol

same with the at-odd and at-even; they all work like this

lyxal

@hyper-neutrino is that supposed to replace the items with their length?

hyper-neutrino

nope, it takes the length of the whole list and replaces elements at those indices with that value

it looks like it's supposed to replace items with their length

but that isn't how it's implemented

granted, this is actually fairly reasonably designed because you can just stick a euro after the L and the other way around would not be possible

lyxal

@hyper-neutrino wait tf?

That doesn't seem very helpful / golfy

hyper-neutrino

10:15

i don't think i've found a proper use for that functionality yet

either i just use euro or the thing i do vectorizes anyway so it doesn't matter

sticking a euro after it doesn't always work either because it will then run it on each index and mask, so if there are any errors thrown you can't bypass those

okay so here's undeniable proof that we are in a society:

'we' can be represented by unicode array [119, 101], where each number is index of character in unicode table
Array [119, 101] has 2 items in it
'in a society' can be represented by unicode array [105, 110, 32, 97, 32, 115, 111, 99, 105, 101, 116, 121], where each number is index of character in unicode table
Array [105, 110, 32, 97, 32, 115, 111, 99, 105, 101, 116, 121] has 12 items in it
Number 12 is even, just like 6 is
Alright, so now 'we' = 2 and 'in a society' = 6
Take a closer look at number 2, which represents 'we'

generated here

actually, here's a better proof that we live in a society:

'we' can be represented by unicode array [119, 101], where each number is index of character in unicode table
Array [119, 101] has 2 items in it
'a society' can be represented by unicode array [97, 32, 115, 111, 99, 105, 101, 116, 121], where each number is index of character in unicode table
Array [97, 32, 115, 111, 99, 105, 101, 116, 121] has 9 items in it
Alright, so now 'we' = 2 and 'a society' = 9
