The Nineteenth Byte

@lyxal Wait wdym

You mean I forget / at the start if it's an absolute path?

@RydwolfPrograms imo Rust isn't much like JavaScript

I feel it's more like someone told C++ to go f*ck itself, so it did, and Rust was the product. Thankfully, the government took Rust away from C++ and handed it over to Haskell to raise

@user they probably just mean that ur username is "user" so like usr could refer to multiple things

Ohhh

@AidenChow this is the joke :p

There was a user called usr

I think 2x-1 or someone called themselves that temporarily

whos 2x-1

@AidenChow @lyxal

@AidenChow one of the greatest golfing minds I ever knew :p

Creator of multiple esolangs and golfing languages, the first non-me Keg and Vyxal user and a good friend

What happened to them anyway?

did he change his username or what... i cant find him?

@lyxal wats keg

update: it didn't work, trying something else

I'm almost out of something elses to try :b

1:07 AM

@user good question

@AidenChow well you see that's the thing - they deleted their account several times

And github accounts too

Notice how I pluralised accounts

chat.stackexchange.com/users/409789/petstorm

waaat... why they doing that

Eh you get used to it

wat

@AidenChow someone clearly doesn't know their esolang history :p

@user last I saw of 2x-1 was a follow on a weird looking a51 proposal that wasn't pldi

The proposal has since been closed and deleted for inactivity

(not pldi)

@Ginger this happened about 4 times I think

Come to think of it, how did each new account manage to be linked to the same chat profile?

so what happen... they delete their acct and never make a new one??

1:11 AM

me when parameter passing for argument of type ‘std::vector<long long unsigned int>::iterator’ changed in GCC 7.1

@AidenChow their last account was in August 2021: codegolf.stackexchange.com/a/233830/78850

we doing all sorts of cursed stuff today

> 4-month hiatus

Narrator: it was not

@AidenChow fun fact: if it wasn't for 2x-1, I wouldn't have come back to code golf in early 2019, I wouldn't have ever made a sbcs esolang and I wouldn't have stuck with the golfing language design grind as long as I have :p

Well, mid 2019 actually

Because may is the middle of the year

spongebob narrator: 2 years later

(I was going to insert an image here but I couldn't find one ;-;)

really hope this thing works

will be big sad if no

Did it work?

1:22 AM

still compiling lol

of course nobody ever expected someone to try to run this on a Raspberry Pi of all devices

@lyxal Are they okay?

^

@user good question

I would assume so

we almost at 50%

@user Hard to tell when there's no active accounts to communicate with :p

1:25 AM

gonna close firefox so it goes faster, see yall later

o/

@lyxal :(

Never knew this person but still sucks they're not active here anymore

Maybe they got a life and took up bowling :P

@lyxal u should ask them for discord or smth next time u see them

> next time you see them

Bingus I've never met them

Just like I've never met any of y'all

~~stalker time~~

@lyxal wait how u know that was their alt acct anyways??

1:29 AM

I uh, huh that's actually a good question

I forgor

Ah yeah github activity

Basically, I saw contributions and interactions with repos I knew they had previously been interested in

then how u figure out when they delete github accts?

I haven't

I don't know why that happened

so they link their github to the alt acct and u look in the activity of that github acct? is that wat u saying?

1:51 AM

I noticed the account interacting with some of my stuff and looked at the account and deduced it was the same account

Lang Design is the best part of CodeGolf IMO...

It really do be

idk anything about lang design :((((

Don't even have to make good langs

Just, write something that takes bytes in and thinks about it real hard

@AidenChow basically it's a matter of step through instructions using rules you create

And then figuring out how to turn instructions provided by users into instructions your code can understand

1:58 AM

ya idek how yall think of all these good lang ideas

That can range anywhere from using a visitor approach with a lexer and parser to just going character by character through a program

@AidenChow doesn't need to be good

Just needs to be fun

@lyxal tf is a visitor approach and lexer and parser

That's my point. You might not even need to know what that is to make a language

(but to answer the question: a lexer says "hey this bit of text is a number, that bit is a string, oh hey and this bit of text is an opening bracket" and so on. A parser says "hey this number, operator and number are a single unit of stuff imma group that together". A visitor approach says "I'll start at this group of stuff, move to the next stuff and so on and each group of stuff might be handled differently")

sound too complicated for me lol

Depending on the complexity of the language, you might not need it

E.g that'd be overkill for brainfuck, and completely out of the question for befunge and ><>

And you can always just have a character pointer to keep track of where you're up to in a program if commands are single characters

2:07 AM

the entire process of lang design sounds like super long and pain... like im literally gonna run into a million bugs before i even get simple program running

Not necessarily

Something like hq9+ or dead fish can have a simple interpreter whipped up without a million bugs

You might have one or two, but no more than that

Besides, once you get started doing lang design, you get used to it, and you start learning what to avoid when making languages

ya that sound like a steep learning curve

It's not. You start with "if I get command x, I do something. If I get command y, I do something else..." and then figure out how to break things down into command x and command y

There's no right way to do it. Sure there's ways which aren't as scalable or easy as others, but as long as it works

I started with Brainfuck, then Reverse Polish Notation

Brainfuck is a good first language to implement

As is something like befunge or ><>

2:16 AM

@lyxal i already do that before

Oh then you already have an idea of how to implement languages

ya but that one was kinda simple... i think more complex one will be super long and hard

@AidenChow I recommend Reverse Polish Notation

48

Q: Reverse Polish notation

You must evaluate a string written in Reverse Polish notation and output the result. The program must accept an input and return the output. For programming languages that do not have functions to receive input/output, you can assume functions like readLine/print. You are not allowed to use any...

From there, it's really easy to add your own commandlettes and make a turing complete language

@ATaco man that looks way too complicated :(

Don't let it daunt you, it's the same concept as Brainfuck but with a different memory structure

Split the program on Spaces

For each substring, perform an action. Numbers push a number to a stack, operands pop two values and push the resullt.

2:29 AM

oh shoot i didnt even realize u can do that

ok then it doesnt seem that bad
