Hmm, what's our site ID?

Can't find it in full.js

Seggan

cmon just one more upvote and I’ve hit the rep cap

Catija

You've got an hour.

Rydwolf Programs

716

That's our site ID

Presuming 718 is our meta lemme check

Nope 717

Seggan

@Catija yeah that’s why I’m anxious

Henry WH Hack v3.0

@RydwolfPrograms Nice, how did you get that number?

Rydwolf Programs

23:06

Ended up just using the Network tab

Henry WH Hack v3.0

Inspect Elements?

Rydwolf Programs

Ooh wait, can you even watch the questions in a private beta if you're not in it?

The watch sockets don't authenticate right?

Yeah no they don't

Interesting

Henry WH Hack v3.0

@RydwolfPrograms Yes using the visit link on Area51.SE. After clicking that you will be taken to a login page, just click on the home link.

Seggan

@RydwolfPrograms can you still commit

Rydwolf Programs

Gah so many good questions and answers

Half my vote limit's gonna be stuff from the previous UTC day

Bbrk24

23:09

There's at least two things I'm going to upvote as soon as I'm able to in about an hour

Rydwolf Programs

Wait hang on I hope the API works for betas

Lemme go check

Henry WH Hack v3.0

I think it does I made some queries in the API for a private beta site before. The Data Explorer won't work for private betas.

Rydwolf Programs

Yep it does

nice

When our subdomain changes it's gonna break the bot, but oh well

Bbrk24

oh my. Look at how I implemented while loops over a year ago

case nodes.StatementType.WhileLoop:
    for (;;) {
        condition = evaluateStatement(statement.condition, scope).val;
        if (typeof condition != 'boolean') throw new TypeError();
        if (!condition) break;
        const result = interpretAST(statement.body, scope);
        if (result !== undefined) return { val: result, propogateReturn: true };
    }

Seggan

Fun

Bbrk24

23:12

Yes I wrote this interpreter in JavaScript for some reason

Seggan

@RydwolfPrograms when?

Rydwolf Programs

We're probably getting it changed to pldi or langdev or similar

There's a meta question atm

Q: What's the right domain name for this site?

The domain name for this site is languagedesign.stackexchange.com. I've been a programmer for more than two decades, but when I read it I still fail to comprehend it's about programming languages, unlike e.g. our sister site about Constructed Languages. Also, the title says implementation questio...

Seggan

Yeah I’m that, but ure so sure

Ooh we have a nice room ID

Q: What are some ways of reporting compilation errors?

What are some good ways to report errors when compiling code in a new programming language? One answer may be to just stop after the first error, but this can be unsatisfactory because it takes additional time to fix the error, re-compile, and then fix the next error. In contrast, if the language...

Q: What are advantages and disadvantages of C-style for loops?

There are two kinds of for loops: the kind that Python has, also called a "foreach": for i in [1, 2, 3]: print(i) and the kind that C has, which is syntactically heavy: int arr[] = { 1, 2, 3 }; for (int i = 0; i < 3; ++i) printf("%d\n", arr[i]); Some languages, such as C#, have both, but I'...

@Seggan what is that from

Catija

Tour

Seggan

I managed to get the other half

Rydwolf Programs

Okay I now have NPSP configured for PLDI, I just need to get it to persist in this room

lol I just found this buried in the code:

Ginger

23:20

sus

Rydwolf Programs

Someone forgot to change the room name when switching to prod room :p

Ginger

@RydwolfPrograms mmmmmm

I am pleased

@RydwolfPrograms wait why tf are you hardcoding your URLs

Rydwolf Programs

I had to do this one, it's a base URI

Ginger

Don't you just give the room ID to your chatbot lib?

Rydwolf Programs

I don't have a chatbot lib

Seggan

23:21

He doesn’t have one

Rydwolf Programs

I am the chatbot lib

Ginger

skill issue

Seggan

Oof chat delays

Rydwolf Programs

NPSP's so tightly integrated it doesn't make sense to factor out the chat stuff into a separate library

And since there was no existing Rust chatbot library, since I maintained the only semi-functioning chatbot library at the time and it was in Node and had dead bodies in it, that wasn't there as a reason to convince me to use one

Seggan

I should make that rust chat library we all need so much

Rydwolf Programs

23:23

@Seggan I'm working on one too

We should team up :p

Seggan

Esp since I’m working on lightchat

@RydwolfPrograms yeah /srs

Bbrk24

Thinking of putting a joke answer on my for loops question:

#define ever (;;)
for ever {}

I won’t actually put that

Ginger

Yeah, I do kinda have a monopoly on the chatbot lib market

Rydwolf Programs

Yeah chatbot.py is totally broken, I've had to make several tweaks to the copy OSP uses

Ginger

Well, not a monopoly

SOBotics are kinda doing their own thing tho

Rydwolf Programs

23:26

While the thing old NPSP and old VyxalBot used is still technically functioning, like I said, decaying corpses

Bbrk24

I wouldn’t mind writing a bot in Rust honestly

~~better than Python~~

Rydwolf Programs

I had to write a custom HTTP library that handled cookies and everything

lyxal

@RydwolfPrograms not really - it stopped working for us

Ginger

@RydwolfPrograms use sechat! Feel the power!

Rydwolf Programs

@Ginger Go convince caird then :p

They wrote OSP not me

Ginger

23:27

@RydwolfPrograms can confirm, I was the one that had to port Vyxal Bot from it q:

Rydwolf Programs

Wait really? lol sorry I made you go through that

Ginger

"Abomination" is too charitable for that mess

But now VB uses sechat v2 and it's way better

Rydwolf Programs

It's Node's fault

Ginger

But of course

Tell me, why did you decide to make it in Node?

Rydwolf Programs

It's the only backend language I was comfortable in

I could've done Python but chatbot.py was already seriously showing its age

Ginger

23:29

Thank Skeet for that "was" :p

Rydwolf Programs

So I'd have had to do the same amount of work either way

(I assumed)

(wrongly)

Bbrk24

Say what you will about JavaScript, it’s an incredibly portable language

Seggan

@Bbrk24 YES

@Bbrk24 Java(VM) is more

Bbrk24

No, it’s incredibly difficult to get Java code running on iOS

Seggan

Ok barring iOS, apple is too selfish

Bbrk24

23:33

The JVM breaks some of LLDB’s assumptions, so even when you do get it running you can’t debug it

Rydwolf Programs

Java also doesn't run on the web natively

Wait nvm

It doesn't do so nowadays

Seggan

Java was designed for the web silly

@RydwolfPrograms GWT would like to disagree

Bbrk24

Also, TIL D has built-in ObjC interop. …why?

Ginger

--why not---

Bbrk24

If you’re not interfacing with Apple’s frameworks, there’s not really a point, is there? The only other language I know with built-in ObjC interop is Swift, and that was made by Apple

Rydwolf Programs

23:42

Okay I just built NPSP

About to try it

yay!

No errors yet

I'll have to wait until someone posts a question to see if it's really working

Q: What are some options for function definition syntax?

What are some ways that existing programming languages handle function definitions, and what are the pros and cons of each method? By "function definitions" I mean either named (i.e. function foo(a, b) { return a + b; } in JavaScript) or anonymous (lambda) functions (i.e. (a, b) => a + b in JS). ...

Q: What are the advantages/disadvantages of prefix types on functions

Famously, C’s functions have their types specified before the function name: bar foo() {…} Most older C derivatives also use the prefix syntax (e.x. Java, C#, C++). However, many newer languages (e.x. Rust, Kotlin, Typescript) use a postfix type syntax for functions: function foo(): bar What ar...

Whoa that was fast

first question also

Rydwolf Programs

Yeah, it's slower than I'd like but workable

I can halve the average post time but it reduces the reliability

Wait did we just ask the same question twice?

Q: Utilising recursion schemes when implementing compilers

I haven't personally seen much use of recursion schemes when building compilers or interpreters, and I'm honestly not quite sure why. Almost all the common ones (cata/ana/para/apo) seem quite handy for various tasks, especially when manipulating ASTs. Is this just because most implementation lang...

Rydwolf Programs

Unacceptably slow smh

GitHub's updated if y'all want to see the updated code for some reason

Ginger

nah, I like my eyeballs

Rydwolf Programs

Nah this code's nice and clean for the most part

Well, aside from the fact that it's async Rust that does multiple things at once so there's so many Arcs it'd get shut down by the fire marshall

But yeah I'mma go ahead and push this to the droplet

Seggan

YES hit rep cap just in time

@RydwolfPrograms lol arcs are my savior from the borrow checker

@Seggan you're welcome
