The Nineteenth Byte

Rewriting all the built-ins in Cthulhu. I will decide on the architecture later in the development process. It's going to be a long-time project to assure it's not a failed first language :0

Step Hen

@dzaima and there's a link to a pastebin

Mr. Xcoder

I am reticent when it comes to a stack-based approach though :/

But it won't be tacit either

Hmm

HyperNeutrino

prefix it

Even worse, use Anyfix :D

Step Hen

9:39 PM

why does no one like infix

HyperNeutrino

too hard to ~~use~~ implement

prefix is nice (just a lot of getNext()) and postfix is nice (stack); even anyfix is easier than infix with OOP.

Step Hen

@HyperNeutrino you use python don't you

HyperNeutrino

@StepHen yes :3

Step Hen

and my parser does infix with ease

no it's easy to implement

HyperNeutrino

mine does too (

PatternMatcher([('expression',), ('binary_operator', 'binary_operator', tuple(elem for elem in row if elem not in special)), ('expression',)], lambda x, y, z: y.addChild(x).addChild(z).addType('expression').rmType('binary_operator')) for row in lexer.binary_operators

)

Step Hen

9:40 PM

at least if you are already doing ASTs

Mr. Xcoder

@HyperNeutrino Yeah, that's what I think I'll do (but I'll write the interpreter after I design the actual language)

HyperNeutrino

@StepHen well that's the thing; most people don't for golflangs.

@Mr.Xcoder Ah okay

Step Hen

@HyperNeutrino cQuents automatically closes parens

HyperNeutrino

lol

Step Hen

@HyperNeutrino and you said it was hard to implement, not ungolfy :P

HyperNeutrino

9:41 PM

Huh I wonder what my first non-Java answer was.

@StepHen well I mean ASTs aren't the easiest things in the world (though they've gotten easier for me as I've used them more, as in twice)

Mr. Xcoder

Sorry. Moved to mobile because i have a netfall and I must use cell data

HyperNeutrino

rip :(

Well turns out my fourth answer is a Java answer that makes a Python program that does the task (as per the spec)

And my fifth is BF.

Mr. Xcoder

Bye, netfall again and I'm out of cellular data :'-(

o:

HyperNeutrino

rip :'-(

before I knew about the 44 meme

Mr. Xcoder

Yaay, wifi again

HyperNeutrino

9:44 PM

yaaay

Mr. Xcoder

@HyperNeutrino BTW, in that answer, can n%2==0 be n%2<1?

HyperNeutrino

yes, thanks.

Mr. Xcoder

@HyperNeutrino Oh no, negatives

HyperNeutrino

Oh right.

Because Java % keeps the sign of the left side, not the right side.

Mr. Xcoder

repcap 2 days in a row :o

HyperNeutrino

9:46 PM

:o

nice

I haven't repcapped in a while :3

;_; lol

Mr. Xcoder

@HyperNeutrino What is your epic badge progress?

HyperNeutrino

9/50

Mr. Xcoder

Just curious

@HyperNeutrino Haha, I have 13/50 and will have 14/50 in an hour and a half or so :P

HyperNeutrino

:(

Mr. Xcoder

Sorry for responding late, it still runs slow

BTW, out rep graphs are nearly identical in shape :)

HyperNeutrino

9:48 PM

that's alright i don't check back that often

hey that's cool :3

Mr. Xcoder

(Ignore the fact that you have more) :p

HyperNeutrino

:P

(I got yours and mine backwards ;_;)

Yours is still steeper :P

Mr. Xcoder

Another Hydra slayer?

HyperNeutrino

Also you edit/flag/vote more than I do.

Or rather, more that I have in the past 3 months.

Mr. Xcoder

Yeah, that I know

HyperNeutrino

9:50 PM

:P

Mr. Xcoder

That member for 3 months bothers me >_>

Now, gotta work for Cthulhu

I work on built-ins at 1 AM in the morning >_>

CMP: Sleep or Cthulhu?

ATaco

Cthulhu

dzaima

@Mr.Xcoder I work on SOGL sometimes from 2 AM to ~6 AM :p (also Cthulhu)

Mr. Xcoder

@ATaco That's what I would've picked too +1

HyperNeutrino

@ATaco hm what happened to recommending sleep huh? xD

@StepHen Maybe I should have listened to you about not using regex lexers...

My lexer is borking on all multibyte operators ;_;

Mr. Xcoder

9:56 PM

New face (inspired by my monster): «_«

HyperNeutrino

huh fixed

easy fix all I needed to do was not be stupid

Mr. Xcoder

I cannot focus with TNB open, so I'll have to leave. Bye!

o/

HyperNeutrino

I was doing [a for a in [b for b in c if d] if e] rather than [b for b in x if d and e] ;_;

o/

How to for loop: for i=0i<10i=i+1print(i)

Proton is surprisingly golfy

but += doesn't work lol

because lexer errors (ノ°Д°）ノ︵ ┻━┻

uh nvm I was just being dumb, fixed.

Hey fun fact: TNB room join/exit animations are back :D

Step Hen

10:19 PM

@HyperNeutrino animations happen when there are <32 active users

@HyperNeutrino and RE regex and infix, I figured out on the car ride home why you don't like infix: they don't go together too well

Wheat Wizard

I made a lost Quine!

Step Hen

@WheatWizard nice

Wheat Wizard

@DeadPossum I've posted my quine. If you outgolf me I'll still be willing to provide a significant bounty. (that also extends to everyone else)

2EZ 4RTZ

I have a genius idea

This involves GoL tetris

I am going to try and solve it with an idea I had

But first some Dota to relax

DJMcMayhem

10:35 PM

@WheatWizard So... You found a lost quine?

6

ppperry

Interesting question: what percentage of a Lost program's characters have to be redirectors to avoid an infinite loop?

2EZ 4RTZ

@DJMcMayhem I think you should just leave

Step Hen

@2EZ4RTZ why, it's already been solved

2EZ 4RTZ

@StepHen wat?

Step Hen

@2EZ4RTZ the Quest for Tetris guys are doing answer writeups, I played GoL tetris yesterday

2EZ 4RTZ

10:43 PM

@StepHen bs

Step Hen

@2EZ4RTZ github.com/QuestForTetris/WriteUp/blob/master/Overview.md

bottom for instructions on how to play

or the chat around here:

5 hours ago, by MD XF

Oh wow

2EZ 4RTZ

kmn

ATaco

10:55 PM

Oh my gosh, they actually did it, the mad men.

trichoplax

@StepHen What's the frame rate like...?

Step Hen

@trichoplax it's fine, but it's also not running it in GoL I believe

ASCII-only

@ATaco it's probably time to golf it by >99.9% then :P

Step Hen

@ASCII-only well good luck, they built a computer

trichoplax

Oh I see - proof of concept now that they have something that in principle runs in GoL?

Step Hen

10:58 PM

@trichoplax no, it's written basically in assembly

the assembly can run locally or on their computer

although I might be completely wrong and it might actually be running in GoL

I think it's just running on an interpreter though

trichoplax

But it's in a language that works in GoL, so proves it's possible?

Step Hen

@trichoplax They have a computer in GoL that can run it, yes

I believe the output there is the meta pixels

ASCII-only

@StepHen Yeah? Using metapixels

Step Hen

they can make the meta pixels in GoL

ASCII-only

which I think is super overkill

trichoplax

11:00 PM

I did not think I would live to see this day

Step Hen

@ASCII-only well you obviously didn't make it :P

ASCII-only

@StepHen yeah

but what i mean is logic gates + clocks exist using glider guns

trichoplax

I thought overkill was what the question called for...

ASCII-only

i thought it was a golf >_>

Step Hen

@ASCII-only well, do it then :P

ATaco

11:01 PM

They actually wrote an assembly language in GoL and it's my favourite thing this site has ever done.

Step Hen

@ASCII-only it is, their computer and what not is golfed as best as possible

ATaco

Get ready for news coverage.

ASCII-only

possibly could be compacted if you only have one glider gun but probably not

Step Hen

@ATaco you bet

ASCII-only

@StepHen not exactly

it just works and that's good

Step Hen

11:01 PM

@ASCII-only as I said you do better, they only made it as big as they needed (which is still massive)

trichoplax

As with any golf, the easy brutish solutions come first, then elegant but much more difficult to craft solutions later

ASCII-only

@StepHen this one is basically a POC i think, if this works then they can just make a glider CPU backend

trichoplax

I wouldn't expect the first working tetris implementation to be minimal

ASCII-only

exactly

Step Hen

I know Phi was talking about reverse golfing Cogol to golf the assembly better

ATaco

11:02 PM

Did the team invent this wireworld cell?

Step Hen

Is there a symbol for sequences like ∑ is for series?

trichoplax

The Sigma just indicates you should sum the sequence, so I'd guess leaving it off indicates the sequence?

ATaco

Ah, It was already a thing

Step Hen

@trichoplax yeah but I need a symbol for when I can't leave it off :(

trichoplax

Ah

Step Hen

11:04 PM

at least how my interpreter works atm

ASCII-only

Sequence

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. Formally, a sequence can be defined as a function whose domain is either the set of the natural numbers (for infinite sequences) or the set of the first n natural numbers (for a sequence of finite length n). The position of an element...

Step Hen

if you need to set any parameters or anything the mode is the break - and I currently have : for sequence, ; for series, and ? for "is it in the sequence", and I'm trying to implement SBCS now

ASCII-only

$T_n = <formula here>$

Step Hen

@ASCII-only I have that open, I'm looking for a symbol still :P

trichoplax

> When a symbol has been chosen for denoting a sequence, the nth element of the sequence is denoted by this symbol with n as subscript; for example, the nth element of the Fibonacci sequence is generally denoted Fn.

ATaco

11:05 PM

@ASCII-only (Please imagify that for those without the userscript)

ASCII-only

@StepHen a

@ATaco don't have the userscript :|

ATaco

Than why are you writing mathjax O.o

Step Hen

@ASCII-only I'm not using it like that, I need a symbol that means "the following identifies a sequence", not the following identifies an item in the sequence

ATaco

Step Hen

or at least, a would look wrong in my syntax

trichoplax

11:06 PM

Hmm, your renderer doesn't seem to support "formulahere"

ATaco

Which renderer does..?

trichoplax

:P

Step Hen

@trichoplax Pseudo code: fetch a random formula from OEIS and parse it into MathJax

discussion hyperlinks

ASCII-only

@StepHen a is the sequence, a_n is the term

Step Hen

11:09 PM

@ASCII-only I know how that works, but the way my syntax is, <params><mode><sequence definition>

and I need a mode identifier for sequence mode

ATaco

Fibbonacci.

Step Hen

the way ∑ identifies a series

ASCII-only

@StepHen a :P

Step Hen

@ASCII-only but... a means "pass me the nth term in the sequence" not "this is a sequence" :P

ASCII-only

@StepHen well there is none? sigma = sum, pi = product

@StepHen no?

Step Hen

11:12 PM

@ASCII-only that's what I was afraid of

ATaco

∏ = Product

HyperNeutrino

@totallyhuman what are you doing o_O you keep breaking the chat animations. First you left and joined at the exact same time and then everyone moved left and slid over your avatar :o

trichoplax

If it only needs to be an easy to remember thing, rather than consistent with literature, could you just use a lowercase sigma?

ATaco

σ

Step Hen

@trichoplax probably, that's a good idea

or I might just stick with : to keep it easy

HyperNeutrino

11:21 PM

@ATaco σ_σ

Step Hen

@trichoplax oh noes σ is divisors

Jordan

sup guys

trichoplax

@StepHen It's many things - good luck finding a symbol that doesn't already mean something else...

Step Hen

@trichoplax yeah but I actually wanted to use divisors

trichoplax

@HyperNeutrino I saw this coming...

Step Hen

11:22 PM

I just didn't know what the symbol was :P

HyperNeutrino

@trichoplax heh

in math symbols can mean hundreds of things depending on context

Jordan

Woah Totally Human is a wizard lol

@WheatWizard Nice! You did it!

HyperNeutrino

no wheat wizard is a wizard

totally human is a bot

I mean a human. totally human.

Step Hen

I'm not good at math. What does counted with multiplicity mean?

Or, what's the difference between oeis.org/A001221 and oeis.org/A001222

oh wait does that mean including duplicates?

that's a ~~dumb~~ ~~long~~ complicated way to say that

trichoplax

Yes it means you count the total number, not just the number of different things

ATaco
