@Calvin'sHobbies Calvin's? Your name keeps changing back and forth (I like this one better if you ask). Why the change this time?

Oh

Nov 2 at 18:38, by Calvin's Hobbies

@cairdcoinheringaahing This used to be my old username here, and I've stopped using Helka Homba so much.

Maybe this time you'll stick longer with this name :-D

Calvin's Hobbies

Hasn't changed that much. Like once per year.

I knew him as Calvin before I knew him as HH.

@Calvin'sHobbies No politics-related reasons this time :-)

Calvin's Hobbies

No. Ugh

12:15 AM

I'm finally going to give Funky the splat operator.

yaaaaay :D

You can already do t::apply(func), but I'd prefer to allow func(...t)

What do you plan on using for the syntax?

func(1, 2, ...t) mostly.

(And it's rather easy to add the syntax thanks to my tokenizer)

hm ok

I personally think it should either be *t or t... but ...t doesn't look awkward to me either

0/10 use * because golfier

12:20 AM

* would conflict with some things, and I prefer ...t because of the JS roots.

Funky is very much so not a golfing language.

ah ok

(Although it is fairly golfy in some areas, like variable names being allowed next to keywords)

wait what?

example?

Funky, 21 bytes a=1; ifa print("yes")

!!!

I must say, I disapprove of that lol

12:23 AM

That's fair, it was accidental.

> accidental

?how?

oh I can see how that might happen

The tokenizer greedily matches keywords

oh ok

I could make that happen in Proton by switching two lines xD

anyway gtg o/

12:38 AM

I've got Splats working when calling functions, but still need to make them work for defining functions. Should be easy enough.

12:48 AM

@HyperNeutrino @cairdcoinheringaahing I said that I had got a solution but I don't want to post it because it's brute-force.

yesterday, by user202729

Currently I have a solution to the next OEIS sequence (A000112) (MD5 = 1816cbca5788befa7e8ae62b89f257c2) but I don't feel like posting it because it is brute-force and takes a lot of time calculating for 4. I've tested for values 0 - 4 and it gives correct result. There are still 3 days remaining, if I can't understand the efficient algorithm listed on the OEIS page and no-one post any answer I will post this anyway.

@orlp Sorry for not replying, but the expression ($\lfloor \frac x {lo} \rfloor = \lfloor \frac x {hi} \rfloor $ is effectively equivalent to either the ceiling equal, or $x \over {hi}$ is a whole integer, in the latter case all the values $a$ such that $lo \leq a < hi$ has the same value of $\lceil \frac x a \rceil$ as that of $lo$, so they are all invalid.

Seems that you figured it out anyway.

@ATaco outgolfed

@HusnainRaza ↑ too.

(The semicolon is also optional)

@HyperNeutrino How can you even inject things into Discord? Can you?

Destructible Lemon

golfer?

golfest probably

12:56 AM

@user202729 inject? no, but a bot API exists

it's not great but it exists

uses webhooks

@DestructibleLemon ... what cmc is this?

Destructible Lemon

none

ah ok

golfiest

does funky have a repl?

Yes.

Oct 27 at 22:46, by ATaco

Alright! I made a Repl for Funky!

1:10 AM

ok, then Funky Repl: 5 bytes: "yes"

I suppose that does work.

Destructible Lemon

hah. not even a "yes solution

Splat syntax now added.

It'll work on the Repl, but not on TIO just yet.

Calvin's Hobbies

Splat would be a good language name.

1:34 AM

I wonder how much TC functionality you can get with the concept of splats alone.

@DestructibleLemon is that valid? I don't even know funky

It's not valid.

ok

@Calvin'sHobbies yes, preferably prefix though

(You should totally learn Funky tho)

function(args) would be f*a.b.c or something

@ATaco maybe later

1:41 AM

@Riker Was that a pun?

Destructible Lemon

your funky repl seems glitchy

It is very glitchy.

I should add an option to toggle that syntax highlighter.

It's also on TIO and Here

And rather basic documentation can be found here

@ATaco nope

CMP: Should I give Funky FileIO? On one hand, it makes me feel better about adding functions like require and even the execution of arbitrary JS and JS interfaces, however, it also ruins the "safe" property of it.

Destructible Lemon

3:04 AM

I found a cool game while looking at wikipedia

@ATaco So you added the capability to run a web server, but you're doubting adding File I/O?

That was sort of hacked in, actually.

The webserver code exposes the webserver functionality to Funky, rather than Funky having the functionality.

tehflamintaco.com/main.js

@ATaco Google translate thinks that's norwegian

@ATaco Yes you should add file io. I don't think that sort of "safety" is something to be desired.

@ATaco you could just use JS syntax highlighting, it would work 99% as well as the one you have therer

6:20 AM

Still I find the :: looks like C++ namespace/struct static access. Although you can't use : too.

What is the @ used for?

@user202729 that's not what it means in a lot of other languages...

@user202729 @ is essentially (a,b)=>a+b where + is the operator immediately after @

9:36 AM

@ASCII-only Outputs aren't included in the permalink. However, TIO would fail, because there's a size limit on outputs.

no i was thinking since it can't be generated fast enough to just compress it

turns out all that did was crash my Sublime >_>

Anonymous

You would also run into memory limits on TIO, even with compression, because you would still have to decompress it (unless you did some sort of streaming compression that could decompress digits in chunks)

Anonymous

I guess you could do naive decimal compression, where you store each digit in a nibble, so you could decompress and output 2 digits at a time

Anonymous

But that's only ~50% compression, so it would still be too huge

charcoal would probably use base 10 to 256 compression

which is only slightly better

unless brotli somehow performs magic

but really nobody can really tell the difference if it's over 128kb :P

Anonymous

9:43 AM

@ASCII-only Sure, but you could only output digits in 1280-digit blocks

Anonymous

Unless you did bit magic to manipulate sub-bytes

Anonymous

Wait no I did my math wrong

Anonymous

But still - it would be big chunks to output at once without sub-byte manipulation

56 digits per block, decompressing 196 bytes of base-256 at a time

funct"honk" in funky defines a function which takes an argument t and returns "honk"

9:54 AM

@ATaco VSL: fn t=>"honk"

func is acceptable instead of function, You don't need () around a single argument name eg. function a{}, a variable name can exist after a keyword fine, so funca or whatever, The function body can optionally be just an expression, and a string sits snuggly after a variable name.

Can someone give me a link to the PPCG definition of programming language? I cannot find it rn.

Oh no, I started finding the algorithm described in the PDF too hard, I think I'll post the naive bruteforce algorithm anyway.

CMP: Char-by-char or regex tokenizer?

@HyperNeutrino Char by Char

Sounds like char-by-char will be faster. (if you implement carefully)

1:17 PM

For Enlist?

Socratic Phoenix

@HyperNeutrino Char by char, just smush everything together and hope it works!

(that's what I did...)

@Mr.Xcoder No, for a new language that transpiles down to Python

(I don't want to make an interpreter because that's the worst part of making a language)

(So I'll just make a tokenizer+parser which makes adding features a bit slower but easier)

Any quick feedback on this? I'd like to post it during the next 30 minutes, although I just posted it to the sandbox.

@SocraticPhoenix ಠ_ಠ

Socratic Phoenix

1679 (1523 SLOC) lines of perfect smushed-ness...

1:20 PM

;_; only 1679 lines

Socratic Phoenix

@ASCII-only it is this

what is SLOC

Socratic Phoenix

significant lines of code

@Mr.Xcoder string, use regex only when needed

oh ok

so not comments and blank lines

1:21 PM

it's source line of code.

@user202729 and way harder. if you do it the conventional way it's waaay slower than regex

@HyperNeutrino What you're describing is LLOC.

New idea: use YACC

@user202729 oh huh ok

@Mr.Xcoder seems ok to me

well i guess it's more you're going to have a lot of trouble either 1. writing the grammars or 2. constructing the trie from the frammars

@HyperNeutrino you what? it's not hard...

So just use regex.

@J.Sallé Thanks!

Socratic Phoenix

1:24 PM

@ASCII-only Personally, I find writing the parser less fun...

@ASCII-only I found it hard :P at least for Proton, not for golflangs

@HyperNeutrino for each syntax construct:
parser: 1 line
interpreter: 1 line

if you do it sanely

uh not really

example?

charcoal

Socratic Phoenix

@ASCII-only s/sanely/not in java

1:25 PM

for each syntax construct

But Charcoal is a golfing language.

Quick poll: I'm building a (not golfy) language with a string literal. Should I ignore all \r characters in that literal?

@user202729 verbose mode isn't...

ಠ_ಠ golflangs don't count

yeah but do you need customizable variable types

@HyperNeutrino customizable?

1:26 PM

@ASCII-only Example code with many syntax construct? (I don't know Charcoal at all)

well like can you make your own classes/types

Socratic Phoenix

@NathanMerrill disallow them or don't ignore them... probably shouldn't just pretend they don't exist. (Just my opinion though)

hmm i guess verbose mode doesn't have infix operators yet

ಠ_ಠ

and I mean for adding a new syntax construct it's one line of parser and one if-statement of interpreter

but the base framework stuff is slightly tricky and very time-consuming

*one lambda of interpreter...

1:27 PM

@ASCII-only my code was actually designed semi-decently this time

https://github.com/somebody1234/Charcoal/blob/master/unicodegrammars.py
https://github.com/somebody1234/Charcoal/blob/master/interpreterprocessor.py

@SocraticPhoenix I ignore them in every other spot (mostly because my language doesn't care about whitespace)

:o semi-decently written neutrino code????? what is this?????

@NathanMerrill no

why? If I'm on a windows machine, and I type enter, I pretty much always mean \n, not \r\n

Socratic Phoenix

1:29 PM

But not everyone is on a windows machine...

in which case you're not typing a \r

Socratic Phoenix

And besides, doesn't " usually me "read everything after this, until the next " as literal data"

@NathanMerrill if you want then if platform is windows replace all \r\n with \n.

in all other cases leave it

CMC: Find the highest prime factorization exponent of an integer higher than 1 given as input.

@NathanMerrill Okay then, so imagine a user includes \r in a string... how likely is it that that was an accident?

@SocraticPhoenix right. I was going to do that as well, until I read that Go actually ignores \r

Do you have an example where it would be useful?

if you want to prevent a dyad-monad construct, you can turn the monad into a left dyad

you can also use that to make monads fork like dyads

I don't recall ever using it though lol
