ok

great now it's segfaulting for no reason

probably should comment out the line that sets the recursion limit to a huge number

ASCII-only

@HyperNeutrino Segfaulting because infinite recursion... that's not no reason

HyperNeutrino

oh funnily enough it was the superclass's default behavior that broke it

@ASCII-only well fine I just couldn't find it k :P

hey look

I got the new version of Proton to print "1" from the REPL

ASCII-only

what.

HyperNeutrino

took me a couple of tries lol

other than literals, nothing else works yet. It's a start though! :P

hopefully the framework is set up well enough for me to just start translating

huh apparently Proton had const. I forgot about that.

CMP: Should I allow the customization of keyword to meaning mappings for Proton? So like, instead of if (condition) statement you could change it to si (condition) statement (if you're french :P)

I keep seeing weird control flow statements in Proton's source code and I can't even remember what they do lol

ASCII-only

00:15

@HyperNeutrino Yes. pls

HyperNeutrino

ok

anyway brb in a bit

ASCII-only

@HyperNeutrino link?

ATaco

Alright, now I've solved it in RProgN2, ARBLE, Threead, TacO, MaybeLater and ReRegex. Am I missing any of my languages?

ASCII-only

@ATaco JProgN, APN, Funky

ATaco

JProgN was an experiment. It's not on TIO and it will hopefully never be.

Same with APN.

Although Funky works, that $O(2^n)$ compile time makes it worthless.

Simply Beautiful Art

00:32

xD

ASCII-only

@ATaco Please explain why it's $2^n$ pls

HyperNeutrino

@ASCII-only github.com/alexander-liao/proton

ASCII-only

@HyperNeutrino to the control flow statments...

ATaco

Each time a token is parsed, it not only checks for the next expected token, but checks if this token is a prefix of another token.

HyperNeutrino

@ASCII-only github.com/alexander-liao/proton/blob/…

ASCII-only

00:39

@ATaco But it isn't 2^n....

ATaco

So for each token, it branches into two.

HyperNeutrino

@ATaco That sounds horribly inefficient but my regex tokenizer is probably no better :P

ATaco

And then for each of those two, it branches into another 2.

ASCII-only

@HyperNeutrino D: so verbose

HyperNeutrino

yes

ASCII-only

00:40

@ATaco But what if it's not a prefix... does it really not error/exit

HyperNeutrino

Oh I just realized what comp means

it's a list comprehension. I'm dumb lol.

ASCII-only

@HyperNeutrino :|

HyperNeutrino

:P

ATaco

Each prefix exists as both a token and a prefix of itself. This is so that expression+expression can be matched as an expression, where the first expression is the prefix.

ASCII-only

@ATaco :|

@ATaco ... ... ...

HyperNeutrino

00:45

Wait isn't that something the parser does?

ASCII-only

@ATaco How do you prevent infinite loops then

ATaco

How would this cause infinite loops?

A prefix needs to only fail to be a prefix once.

ASCII-only

But it can be a prefix of itself, how can it fail

HyperNeutrino

gah I'm dumb

ATaco

A prefix of it's token type, not the same token.

Funky was an experiment in a more generic language, which worked, but it was really slow and pretty aweful.

ASCII-only

00:50

@ATaco Then it's nowhere near 2^n...

But yes. If you just fix that... then isn't it fine

ATaco

I assure you that it is 2^n, I'm just really bad at explaining it.

ASCII-only

@ATaco pls prove ty

HyperNeutrino

well now I need to rework my entire memory system, which is really the hard part lol

ASCII-only

like does a 30 term program actually take like >1 second to parse

ATaco

I'm a hobbyist programmer, not a Mathematician, I ain't gotta prove nothin'

ASCII-only

00:52

@HyperNeutrino :| what

HyperNeutrino

currently the memory system uses strange hacks such that rewriting to actually be decent is a pain

ASCII-only

@HyperNeutrino memory system?

HyperNeutrino

actually no what the hell am I doing

@ASCII-only well like the way variables are stored

but yeah what the heck am I doing, I don't need to do any of that

ASCII-only

@HyperNeutrino protip: use Charcoal's Scope then open 100 issues when it doesn't do what you want it to

HyperNeutrino

Okay, thanks.

LegionMammal978

Anyone here know any U.S. politics? (don't worry, I'm not here right now to give out opinions)

muddyfish

01:05

I'll see if I can find it in uni library

Thanks

DJMcMayhem

01:18

@LegionMammal978 I know some

LegionMammal978

@DJMcMayhem Okay, so apparently, President Trump designated Ajit Pai as FCC chairman on January 23 of this year, but all I can find on it is Pai's response statement and media reports of the designation. Where would I be able to find any actual records of the designation itself?

DJMcMayhem

Uhhhhhh

I have no idea

LegionMammal978

Me neither

Checked the FCC records, the congressional records, the Federal Register, and the White House statement listings

Could only find his response

HyperNeutrino

lol my CS class finally got around to actually teaching programming

I wonder how badly I will fail this course simply because of bad coding style

ASCII-only

@HyperNeutrino Not very

HyperNeutrino

01:28

how so lol

I mean then again it's so simple that I can't even screw it up

like maybe the hardest we'll get to is recursive functions I think

ASCII-only

@HyperNeutrino Well apparently most uni programming graduates can't even do fizzbuzz

HyperNeutrino

what.

remind me what that is?

ASCII-only

:|

ATaco

Count up, if the number is divisible by 3, write Fizz, if it's divisible by 5, write Buzz, if it's divisible by both, write FizzBuzz, otherwise, write the number.

HyperNeutrino

it's print numbers ascending except fizz for 3|n, buzz for 5|n, and fizzbuzz for 15|n right

ASCII-only

01:31

Yes

Except not |

HyperNeutrino

i don't see how that's even remotely challenging :|

ATaco

It's not.

LegionMammal978

You know, I still don't understand the difficulty in understanding most cases of recursion

muddyfish

I did that about 9 years ago :(

LegionMammal978

I picked it up pretty quickly

ATaco

01:32

But the number of possible solutions and such makes it a great interview question.

muddyfish

It's really annoying that you've got to get through the lower levels at every stage of education

ASCII-only

@LegionMammal978 example pls

user202729

@HyperNeutrino I feel unfortunate that you have to learn at a level much lower than your programming skill. Does your school offer a harder class?

ASCII-only

@muddyfish yes. it is. :|

ATaco

Don't rush them, you'll never know what you'll pick up along the way, hopefully good habits and not using namespace std

ASCII-only

01:33

@ATaco I know good habits though >_>

LegionMammal978

@ASCII-only idk, programming courses seem to make it sound real difficult, looking at others' anecdotes

ATaco

Then you should breeze through it :D

HyperNeutrino

@user202729 Nope. Grade 12 is probably what I learned 2 years ago. Headstarts are both great and boring.

ASCII-only

@LegionMammal978 do you have a link to one such anecdote

@HyperNeutrino Do you not have AP CS wherever you are

ATaco

Year 12 taught me literally nothing about programming.

LegionMammal978

01:35

@ASCII-only ¯\_(ツ)_/¯

HyperNeutrino

@ASCII-only Nope.

@LegionMammal978 you lost an arm

(edit-ninja'd)

LegionMammal978

What if there was a site which could display ¯_(ツ)_/¯ or ¯\\_(ツ)_/¯ but not ¯\_(ツ)_/¯

ASCII-only

@LegionMammal978 There probably is

HyperNeutrino

I would murderize said site.

Except such a bad site would probably be a creation of mine lol.

ASCII-only

@Mego Why not :P

ATaco

01:37

With credit to my school, they didnt offer any course claiming it would teach me anything about programming.

ASCII-only

@HyperNeutrino *Taco's

HyperNeutrino

oh sick burn

ATaco

My year 10 course did the generic "This is HTML, make a terrible webpage"

@ASCII-only I'll have you know my sites are perfect.

HyperNeutrino

I skipped grade 10 CS ¯\_(ツ)_/¯

ASCII-only

@ATaco Isn't that what all Year 10 courses do

> .jsd

muddyfish

01:38

I'm learning Java this year. I haven't used Java before. I guess I'll be learning the syntax of Java. It's pretty simple so far

ATaco

@ASCII-only Yep.

@ASCII-only .jsd is perfect.

ASCII-only

@HyperNeutrino If I did CS I would skip the first two years of the uni degree

HyperNeutrino

lol

ASCII-only

@muddyfish if you know a C-derived language it's pretty easy

I have a friend in second year, they're doing networking in C

sounds terrible right?

ATaco

Before Java I hadn't used any Strictly typed langauge.

And it was basically the best thing.

ASCII-only

01:39

but they get a library that basically does everything for them >_>

ATaco

That is infact how you write C.

@ASCII-only Do these bad practices make you cry?

ASCII-only

yes

user202729

@ATaco But that is js.

ASCII-only

typing const 4 times ;_;

@user202729 On the server. >_>

muddyfish

I know python and it's pretty simple. I just dislike it's types and not quite compatible methods

ASCII-only

01:41

@ATaco Is this express

@muddyfish not quite compatible?

ATaco

@ASCII-only Nope, just .jsd

muddyfish

Array and List and the primative array for example

ASCII-only

@ATaco no i mean are you using express for server

@muddyfish array?????

ATaco

@ASCII-only Nope, just Node.JS

ASCII-only

@ATaco ... no i mean are you using http/https module? or express module...

muddyfish

01:45

I can't really remember. This was issues I had about 2-3 years ago when I was playing about with it. Haven't gotten to arrays and lists yet in the course

ATaco

@ASCII-only Just plain ol' https, You could probably have assumed this when I repeatedly said "no" to the question "are you using express"

ASCII-only

@ATaco .jsd is not https, neither is Node.JS...

ATaco

The point was that I said no to the question "Is this express"

Which means any future question, saying "is this express or..." probably assumes the latter.

Regardless, Express would have probably been logical and infinitely easier to work with, which is unacceptable.

@ASCII-only I'll have you know my sites are perfect.

ATaco

Absolutely perfect

The idea behind my JSD system was to allow for me to rapidly prototype webpages, and it achieves that perfectly.

858 was a neat thing I pushed out quickly.

muddyfish

01:55

I use aiohttp, jinja2 and Firefox's web developer tools

ATaco

If you're going to do something, might as well reinvent it!

ASCII-only

> Firefox's web developer tools

ATaco

I use them too.

ASCII-only

@muddyfish aiohttp?

muddyfish

An alternate to flask that uses asynchronous programming

Works nicely with other things such as apscheduler and discord.py for example

ATaco

02:05

I made snake in 858. Yay.

ASCII-only

@ATaco :| it freezes if you eat yourself

ATaco

Patched. Refresh.

But it is terrible for golfing.

ASCII-only

@user202729 Because really C# is much better

ATaco

Sure they both hit balls, but one isn't really suited to the task at hand.
