This one shouldn't, it is just inappropriate.

oh great he rolled back

Step Hen

@totallyhuman yeah... now it's weird again

does that mean "print( ... )" doesn't count?

totallyhuman

i dunno

Step Hen

you know what

how bout we ignore him and just do what we always do

totallyhuman

downvote and move on

@totallyhuman no need to downvote for someone who doesn't know what's up, the challenge is good and the Charcoal answer will come in sooner or later

I just realized that pure and <*> are the S and K combinators in Haskell

Is there a deeper meaning here?

17:20

most common line of @Mr.Xcoder: "You were quite short on tags."

Mr. Xcoder

yep

@EriktheOutgolfer he only had 1 tag which was irrelevant anyway

Erik the Outgolfer

yeah I removed that

it was a tag that didn't even exist...

Step Hen

@totallyhuman I got charcoal to work, but I'm sure it's twice as long as it needs to be

totallyhuman

idek how to print a string of length two lol

Step Hen

@totallyhuman well the way I did it was I printed in the direction without moving, moved right, then printed in the direction with moving

Step Hen

although I think that way would be shorter

Mr. Xcoder

Yay, use all the superscripts!

Step Hen

@Mr.Xcoder I promise it's not optimal

totallyhuman

that's how numbers are in charcoal

Step Hen

yeah ASCII is printed as-is

Mr. Xcoder

17:26

@StepHen It's longer than SOGL. You can do it in half those bytes, I promise

Step Hen

@Mr.Xcoder I can't, Neil could

Mr. Xcoder

Yeah or ASCII

Erik the Outgolfer

@Mr.Xcoder wow that seems so ungolfed...

Mr. Xcoder

I know

Step Hen

@EriktheOutgolfer it is, I don't know Charcoal

it's just "move around and print stuff"

no fancy commands or nothin

if you golf it down post your own :P

Erik the Outgolfer

17:31

heh I'll try

totallyhuman

i out-golfed you by 5 bytes

hah :P

Mr. Xcoder

@totallyhuman s/5/⁵/

Heh

totallyhuman

:P

i use verbose mode so regular 5 for me :P

Mr. Xcoder

Too many Ｐs and superscripts

ah, i still out-golf you by a byte though

Step Hen

@totallyhuman yeah I spent like 25 bytes finishing the top left and bottom right 0.o

28 bytes for most of it

totallyhuman

tip: use verbose version, it's waaay easier

Mr. Xcoder

Trying to outgolf you both :)

totallyhuman

also charcoal could most definitely use a cool interactive IDE

Step Hen

@totallyhuman oh you literally only outgolfed me because I printed the extra tail 0.o

Mr. Xcoder

Once you printed something, how do you continue from there?

cc @StepHen @totallyhuman

totallyhuman

^^^^^^ cc @ASCII-only

Step Hen

@Mr.Xcoder oh the cursor follows you

the M moves the cursor around

Mr. Xcoder

uh, what?

Step Hen

if you use P to print the cursor doesn't move though

arrow number moves the cursor and prints

P arrow number leaves the cursor where it started

Mr. Xcoder

17:51

Multiprint(:DownRight, 12)

Then I wanna print from there... Ah got it

Step Hen

Ｐ↘¹²→↘¹² is Print down right (leave cursor), move right, print down right (move cursor)

Mr. Xcoder

I use verbose

Step Hen

then you can't get satisfactory explanations from me :P

28 bytes for most of it

oh wait me dumb, I have the top part too

Mr. Xcoder

I want to outgolf you. If I don't succeed I'll tell you

You use that anyway, duh

totallyhuman

downright, upright, reflect?

Mr. Xcoder

18:02

prolly

Step Hen

@totallyhuman yup

totallyhuman

ye but y'know...

Step Hen

only I did downright, upright, move up, downleft, move upright, reflect

and then took another 25 bytes to add the tails

@totallyhuman tied you with Jump though

(Any language) CMC: Make a function that will sum all of the arguments (not a list).

I VTC HyperNeutrino's challenge as a duplicate of this one

Step Hen

how do you take dynamic args that aren't in a list? same as python?

Mr. Xcoder

Shh

HyperNeutrino

@StepHen yes

Step Hen

@HyperNeutrino *a=>sum(a)? or do I have that screwed up

Mr. Xcoder

18:05

args and kwargs?

HyperNeutrino

No kwargs

@StepHen nice. It can be 4 bytes though.

(that's right)

totallyhuman

totallyhuman

oh

HyperNeutrino

@totallyhuman no

totallyhuman

that was used for something... i don't quite remember what

Challenger5

///, 0 bytes. I/O is in Unary and input is done through insertion into the source code.

Step Hen

@HyperNeutrino so & makes a function then? :P

Mr. Xcoder

@HyperNeutrino nice +1. We don't really have proton installed, ya know

@StepHen I think & is args

HyperNeutrino

18:10

@StepHen yes :P &func is equivalent to *a => func(a)

There's also !!, %%, and @ for functions

Step Hen

@HyperNeutrino so f=∑ f(1,2,3,4)

HyperNeutrino

@StepHen yes

Step Hen

cool

HyperNeutrino

I need to add my operators to the wiki :P

totallyhuman

yes

Step Hen

18:11

@HyperNeutrino what do those do

Mr. Xcoder

@HyperNeutrino I want to challenge you in a couple of proton CMCs. Can you please join me in the room for Proton?

Step Hen

I want in @Mr.Xcoder

DJMcMayhem

@Challenger5 V, 9 bytes: ÎD@"éi\nØi

totallyhuman

@StepHen ...it's public

Mr. Xcoder

@StepHen Come to Proton

HyperNeutrino

18:12

!! will make the function return a partial function if not enough arguments are given

@ makes the function automatically cache its results

Challenger5

This is impossible in Haskell...

HyperNeutrino

%% makes the function automatically splat the output if it's a list, which can be useful for chaining

$ deletes everything from the cache, and $$ turns off caching

HyperNeutrino

DJMcMayhem

@WheatWizard Holy crap, that's genius. I wanted to do ([])({[{}]{}([])}{}) but that subtracts one per loop. But now it's so obvious to just add the stack height into the push command.

Wheat Wizard

18:18

Its one of my tips :)

DJMcMayhem

Yeah, the one I'm really bad at

totallyhuman

uhh

DJMcMayhem

Wait, is that push-pop redundancy, or something else? Because we don't really need to use the stack height normally, just if we're subtracting

* Circular convolution (`cconv`) implemented as `Z+` with 3 inputs; including Octave compatibility
* `Zc` with a single, non-cell input replaces nonzeros by 35 (ASCII for '#') and converts to char. Thanks to Conor O'Brien for the idea!
* Octave compatibility: `Zd` (`gcd`) and `Zm` (`lcm`) now allow char inputs
* Extended `Zs` with skewness and kurtosis
* Correction for set functions in Octave. The bug afffected Octave's compatibility functions for `setxor`, `setdiff`, `union` and `intersect`. Thanks to Sanchises for noticing!

Oh you changed your picture. I didn't recognize you.

@dzaima that's cool - something go wrong in a SOGL program? :P

dzaima

@StepHen surprisingly, no. Just an idea I had :p

@StepHen for things that did go wrong in SOGL programs, see this

@dzaima bytecount is too embarrassing

I got 1 year Mathematica for free for $400

2EZ 4RTZ

@HyperNeutrino For free for 400?

HyperNeutrino

yup

2EZ 4RTZ

???

Step Hen

@HyperNeutrino why don't you golf in it

HyperNeutrino

I paid $400 to go to the ARML competition (Pennsylvania Division) and ARML gives free 1 year license :P

ohh lol

HyperNeutrino

@StepHen because I have not been able to download it. My wifi always gets cut off halfway in between

2EZ 4RTZ

RIP

HyperNeutrino

it takes so long to download that my wifi cutoff rate is too high for it to download

Step Hen

@HyperNeutrino plug in an ethernet cable

HyperNeutrino

I'll try again sometime
