The Nineteenth Byte

Soaku

18:00

@Cowsquack (sorry, I'm new to CMCs) Can I assume the inputs contains only printable characters?

Zacharý

"You can choose the repeating char"

Soaku

ah, ok then

Poke

@Zacharý yeah i guess the java devs really care about golfing

Adám

@Cowsquack QuadR, 12 bytes Try it online!

Cows quack

@DJMcMayhem I have 10

DJMcMayhem

18:08

My python answer was golfed from 45, to 44, to 38

@Cowsquack Challenge accepted, don't let me see it yet

Cows quack

@Adám how does 1↓⍬ work?

dzaima

@Cowsquack SOGL, 5 bytes. 1st 2 bytes could be removed if 0 was an invalid input

Mr. Xcoder

@Cowsquack Jelly, 3 bytes. Hehe :P

@DJMcMayhem Does the 38 byter work for the empty string test case?

DJMcMayhem

No :|

Although I just fixed it for +0

Pavel

@Cowsquack F#: function|'-'::t-> -t.Length|s->s.Length

Takes a char list

DJMcMayhem

18:17

@Mr.Xcoder Do you have a python solution?

H.PWiz

@Cowsquack @DJMcMayhem I have 9 bytes pure Vim

Riker

@flawr @betseg I approve of this post

also, checkout r/calligraphy

H.PWiz

Oh no, It doesn't quite work

Mr. Xcoder

@DJMcMayhem Of course I do. Currently it's 39 bytes so well done :)

Does yours take input as a string?

DJMcMayhem

Yes

Mr. Xcoder

18:21

I would have 38 if handling "" wouldn't have been necessary.

DJMcMayhem

I also have a 26 byte brain-flak answer :)

@Cowsquack I give up

I'm out-vimmed today

Cat Wizard

@DJMcMayhem What's the challenge?

DJMcMayhem

27 mins ago, by Cows quack

CMC: Given a string that is the unary representation of an integer (negative integers have a - at the start), return the number it represents. You can choose the repeating char ##### => 5, -111 => -3, !!!!!!!!!! => 10, <empty string> => 0

Cat Wizard

Why not ([]<>)?

DJMcMayhem

My answer is sorta cheeky, though I believe it's valid.

@CatWizard Negatives

dzaima

18:23

@Cowsquack JS, 25: (a,l=a.length)=>a<0?1-l:l

DJMcMayhem

24 now

H.PWiz

Now I have 10 bytes pure vim.

Adám

@Cowsquack If input is nothing, gives ⍬. If input is ⍬⍬⍬ gives 1↓⍬⍬⍬⍬.

Cat Wizard

@DJMcMayhem 32

28

DJMcMayhem

@CatWizard Tip: I used 0x00 as the repeating character (which doesn't work on TIO, so on TIO I used char codes)

Cat Wizard

18:28

Ah yes cheeky

Adám

@Cowsquack APL (Dyalog Unicode), 11 bytes ⍎⍕,¨'+/0',⍞

DJMcMayhem

But not invalid ;)

That's pretty similar to mine

Cat Wizard

22 then

@DJMcMayhem Your's is 24?

DJMcMayhem

Yep: {{}([[][]]<>)<>}([]<>{})

Your's is nicer though

Cat Wizard

18

2

DJMcMayhem

18:32

@CatWizard 20 now

Ah dang

Oh clever!

That's beautiful. I had <{}>[[][]()] but that's a nice trick how [[]<{}>[]] is equivalent

Cat Wizard

I don't think the 18 can be beat

DJMcMayhem

@CatWizard That's a really elegant solution

Cat Wizard

Thanks.

H.PWiz

Hmm, my vim answer didn't work for 2 digit numbers. Here it is now 11 bytes

Soaku

Uhh, my answer works for everything but 0

flawr

18:36

@Riker hehe:)

DJMcMayhem

@Mr.Xcoder Counted wrong, I'm actually at 36. Do you want me to reveal?

Cat Wizard

@DJMcMayhem Another 18 this one is a bit easier to understand.

DJMcMayhem

Man, brain-flak competitions are fun.

Mr. Xcoder

@DJMcMayhem Yes, you can reveal. I am eating now so I'll get back to ~~trying to outgolf you later :P~~ your solution later

DJMcMayhem

Sometimes, I think I enjoy CMCs more than the main site

Mr. Xcoder

18:39

^

Cat Wizard

@DJMcMayhem Yeah, especially on relatively simple competitions

DJMcMayhem

@Mr.Xcoder Python 3, 36 bytes: lambda s:[len(s),-len(s)+1]['-'in s]

dzaima

@DJMcMayhem 1-len(s)? :p

DJMcMayhem

Oh doi

I always miss those stupidly obvious things

Soaku

If anyone understands Pepe, I've got this, but it doesn't work for 0... :/

H.PWiz

18:40

~len(s)?

DJMcMayhem

Nope

Neil

@Cowsquack Retina 0.8.2, 9 bytes

DJMcMayhem

That gives negative 5 for -111

Cows quack

too many pings :P

Cat Wizard

Haskell for 30

I'm pretty impressed that Brain-Flak is beating most of the high level languages.

DJMcMayhem

18:42

OK, semi-related CMC: print the first N terms of the following sequence: 1, -1, 11, -11, 111, -111, 1111...

Actually, scratch 0

Cows quack

@DJMcMayhem Try it online!

DJMcMayhem

Nice

Mr. Xcoder

@DJMcMayhem God I was close... I had lambda s:s.count("1")*(-1)**(s[:1]<"1")

Cows quack

@Adám oh, so ⍎⍵ is pre-processing?

now to crack the pure vim solution

dzaima

@DJMcMayhem Canvas, 9 bytes

DJMcMayhem

18:48

@Mr.Xcoder The end could be '-'in s for -2

Mr. Xcoder

I know after seeing yours.

Cows quack

@Adám nice one :)

AdmBorkBork

@DJMcMayhem PowerShell, 50 bytes -- Try it online!

Soaku

I don't know how I made it, but I guess I lost a lot of bytes.

H.PWiz

@Cowsquack Did you see that mine was 11 bytes in the end

Cows quack

18:55

yeah

Soaku

Something is wrong with the link, wait

H.PWiz

It's quite similar to what iI did here

Cows quack

@Cowsquack sed -r, 69 66 bytes, Try it online!

Soaku

Looks like my submission doesn't work online (it does offline), for some reason. Pepe, 86 bytes anyway

Cows quack

@H.PWiz do you think you can beat my V answer?

Soaku

19:00

It didn't work because I haven't pushed my last commit, dammit. Should work in a while

H.PWiz

Probably. Let me look at the docs

Cows quack

do you think this challenge (along with the reverse challenge) would be good on main?

Soaku

yes

Cat Wizard

I feel ambivolent but not apathetic.

Cows quack

I'm anyways thinking of posting it in anagol sometime (as a limited-time challenge) to get to see the shortest sed unary<=>decimal solutions

Adám

19:12

@Cowsquack No, post-processing.

Cows quack

ah, that makes sense

Zacharý

@DJMcMayhem RAD, 22 bytes (with RAD_IO being set to 0) (≢⊢↑⍨'-'=⊃)×1¯1⌷⍨'-'=⊃

H.PWiz

Does V have a synonym for @"?

DJMcMayhem

@H.PWiz No unfortunately, although @ at the end of a program/macro/certain ex commands will implicitly fill in to @"

Zacharý

Correction, that should be (≢⊢↓⍨'-'=⊃)×1¯1⌷⍨'-'=⊃

@Adám I assume ⍎ is implemented either in C/C++, or with a tradfn?

H.PWiz

19:24

@Cowsquack I can't come up with any way to shorten it in V

Zacharý

('Hello',⊢),
('Hello' <function deset1.<locals>.<lambda> at 0x7fb9700f3ea0>)

Ugh, now I have to fix the parser again.

Q: Finding Fastest Frog's Frolicks

A frog sits on a lily pad wishing it were on the other side of the river. There are some lily pads of varying sizes between the frog and the other side of the river. Larger lily pads allow the frog to jump further than smaller ones and the frog wishes to reach the other side of the river in as ...

Cows quack

@H.PWiz okay I'm spoilering myself now, nice use of the space as the separator, that's where I got stuck

Riker

@Cowsquack uh ok aren't you like a rising junior?

that's 2 years of weird name

as somebody who changes his steam name biweekly tha'ts too long per weird name

Cows quack

o_O

H.PWiz

19:39

Will you try this? @Cowsquack

Riker

i.sstatic.net/DpOcp.png 2 were an in-joke with a friend, 1 was 'rikersan' to help somebody friend me easily, 1 was a prototype for another name and only lasted like 5 minutes, the rest are over the last like 4 weeks

Cows quack

> donkey kobg

Riker

yeah I'm borrowing from @quartata's twitter

source

Cows quack

~~I know see the inspiration for quartatertot's tweets~~ oh wait it's the other way around

Riker

@Cowsquack yeah I don't konw where he comes up with this stuff

Cows quack

19:42

@H.PWiz yeah got there

DJMcMayhem

@H.PWiz Why doesn't spoiler work for that?

Cows quack

ZZ at the end

DJMcMayhem

Ah, that's right

Cows quack

like vimgolf

@Riker you might be interested in whatareyoudoinginmyswamp.com (warning sound and video)

Pavel

@Cowsquack Given I'm currently in public with people behind me, is it safe for me to click on that?

DJMcMayhem

19:50

@H.PWiz Ah, I didn't think that was possible in <12, until I realized the answer is really cheap :P

Actually wait, I can only do it in 11... o_O

Riker

that meme died a long time ago. let it stay dead

FreezePhoenix

Hi

Riker

FreezePhoenix

Hi laser cat

Riker

@FreezePhoenix do you just altenrate between blue and yellow avatars?

FreezePhoenix

19:57

@Riker I have a combo one

Riker

lol

FreezePhoenix

101 7

Riker

oh nice

FreezePhoenix

But mostly I alternate (Sorry if it causes any confusion)

Riker

np

Cows quack

20:08

@Pavel not really?

@Riker "crawling in my skin" is one of shrek's best

FreezePhoenix

@Cowsquack So? It still died.

Cows quack

but the url is 10/10

FreezePhoenix

So what

Anyone can put a 10/10 rating on their site!

Yes, it is true... anyone can put anything on their site

Zacharý

20:42

Anyone know how to reset local files to version in a remote repository using git?

FreezePhoenix

Uh... are you using git?

Zacharý

Yes ^

FreezePhoenix

Then look it up ;|

quartata

@Riker i will make a video detailing my process sometime

but i need to make more fake blood first

FreezePhoenix

gasp

Zacharý

20:46

@FreezePhoenix I think I already tried that, but I'll just do it the way I did the last few times: delete the local git folder; then just clone (I just wanted to know if there was a better way to do this)

FreezePhoenix

git reset --hard <branch>

Zacharý

... already deleted it, I'll try using that next time...

Erik the Outgolfer

wow how many active problems over anagol

FreezePhoenix

^ ?

Erik the Outgolfer

golf.shinh.org

anarchy golf

Riker

20:57

@quartata ok then

@FreezePhoenix can they rate things 5/7 though?

FreezePhoenix

yes.

Mr. Xcoder

21:19

@EriktheOutgolfer Oh my god! While PPCG is dying (literally), anagol's activity bursts :o

H.PWiz

PPCG is dying?

Erik the Outgolfer

well, most of them are low-quality though

PPCG can't die so easily, it's a graduated site

besides, Mego and others are already preparing Axtell :P

Zacharý

Can an APLer give me a ludicrous train involving ,, +, -, strings, and numbers? I've been having tons of bugs with RAD's train evaluator.

Mr. Xcoder

Eugh all are KCs? :c

@H.PWiz There are very very few challenges imho lately

Zacharý

@Mr.Xcoder PPCG has sort-of run out of material to use for challenges

Mr. Xcoder

21:23

And pretty much none of them actually atract me much for some reason. I haven't had that golf-enjoyment feeling in a while

H.PWiz

Purely looking at the analytics, I'm not convinced

Mr. Xcoder

Yeah but if you subtract the closed ones and the low quality ones and you compare their frequency to the last summer...

FreezePhoenix

  taxicabDistance( vector ) {
    vector = Vector.attemptConversion( vector );
    var distance = 0;
    distance += Math.abs(this.X - vector.X);
    distance += Math.abs(this.Y - vector.Y);
    distance += Math.abs(this.Z - vector.Z);
    return distance;
  }

Javascript... is not the best for code golf

Zacharý

22:03

V=>{v=Vector.attemptConversion(V);return Math.abs(this.X-v.X)+Math.abs(this.Y-v.Y)+Math.abs(this.Z-v.Z)}

What is this for?

Downgoat

@ConorO'Brien do you know if there is a reason TC39 never did a *[Symbol.iterator] for Object.prototype?
