not print, append. Then after 4 appended newlines append a newline every 6 spaces

8:05 PM

Okay ... I'll probably write some D code then translate it to C.

That works :P

@DJMcMayhem well i suppose PPCG can be a code writing service. As long as you can make it have a winning criterion :P

I haven't gone that far yet

DJMcMayhem

@2EZ4RTZ ...

No

Nvm you misunderstood

#include<stdio.h>
void f(char*s){char c,i=0,j=0;while(c=*(s++)){putchar(c);if(c==' ')++i;if((j<4&&i==7)||(j>=4&&i==6)){i=0;++j;putchar('\n');}}}

@2EZ4RT ^

@TuxCopter wow. that is simpressive

8:09 PM

can definitely be golfed more

"simpressive" when impressive is just not enough

@2EZ4RTZ Could the size of the input be less than the four newline thingy?

@Zacharý no

@TuxCopter Well, it's not outputting, it's just returning.

@TuxCopter Don't worry, his code is completely ungolfed.

@TuxCopter I can't find a way to append to a string in c (instead of printing output return the new output as a char)

Is there a way to do that? SO didn't have a good answer

8:11 PM

Temporary string?

@2EZ4RTZ directly set the chars in the string and realloc if it becomes too big

@TuxCopter So make the spaces = \n

This is why I use D. I hate manual memory management.

Wait, would it be possible to do some of the move counting in a different language?

muddyfish

Before I ask on SO, does anyone know how to wrap a synchronous generator into async code? Sort of like

class BlockingIter:
    def __iter__(self):
        while True:
            return input()

(Python)

@NewMainPosts Why hasn't this had a massive amount of FGITW answers?

@muddyfish shouldn't it be yield input() not return input()

muddyfish

It should but I can't edit now :P

That's just the example of something I want to iterate over in a coroutine

8:36 PM

Can I get feedback on this as a challenge idea?

answer-chaining where, given n, output n in the base that your answer is

e.g. the first answer converts to base 1, the second to base 2 etc

List<string> Lines() {
    string s;
    while((s = Console.ReadLine()) != null) {
        yield return s;
    }
}

@cairdcoinheringaahing Because of input validation.

@Zacharý what do you think of ^^^

Hold on, I found a challenge where MY might be competitive!

@Zacharý He's removed that restriction!

8:40 PM

@cairdcoinheringaahing How to convert to base 300

Shoot.

Now it's FGITW.

Only exit or error.

Stephen

@Zacharý what is SFSDFSFSDFSDFS

Is MY on TIO?

Yes

@Zacharý you know that TIO has a preformat for code golf answers?

8:44 PM

@Stephen I updated it.

ppperry

@cairdcoinheringaahing The answer-chaining there doesn't really mean anything

@cairdcoinheringaahing I've just never used it.

@Zacharý Why not? It automatically has links to the pages required

Plus the byte count is always correct

(except for a few APLs)

If MY actually wins, holy crap.

@Zacharý my Jelly answer is 3 bytes, sorry :(

Shameless plee for help

GRRRRRRR.

@Zacharý Don't worry, now my 05AB1E answer outgolfs my Jelly answer :)

Hello there! My code-challenge question was put on hold. I already made serious improvements, what do you think? You're welcome to cast a reopen vote or give me hints how to improve the question in this SE chat room.

@Zacharý I have no way of alerting the other guy, and I didn't want to high rep user take it, so i want for it

You should try it with APL

One of my challenges got Necro'd

Necro'd? WTF is that?

Very old challenge that got an answer

ATaco

8:56 PM

It's gotten a fair few answers now.

@dessert sorry, but I still think that it's unclear. It is very subjective, which leads to a lot of loopholes. Whats to stop me defining a as a homoglyph of # and using that to circumvent the rules?

Would a challenge about interpreting a decimal number as binary, then converting it to hexadecimal be considered a dupe?

Probably. Regardless it sounds super boring

A: Sandbox for Proposed Challenges

@cairdcoinheringaahing How could you circumvent any of the rules with that? If you define # = a then every occurence of # in the code must give a in the output.

9:10 PM

What notation is the golfiest? Prefix, infix or postfix?

Downgoat

@TuxCopter postfix

k

prefix and postfix are basically the same

But postfix is easier.

easier to write? Its much easier to think in prefix notation than postfix

9:12 PM

@WheatWizard To parse.

postfix is kinda easier to implement

Yeah thats what I meant by write

Why are you asking?

I thought I fixed a bug in MY ... apparently I didn't. >_<

@dessert Then the entire competition is in choosing the language. If the question were open, then the best language would be ;#

@cairdcoinheringaahing Why that?

@cairdcoinheringaahing What abuot number of signs in the code = number of letters in the output?

i tried using rust for code golf... it was a bad idea

THe only time I saw rust for code-golf used was in the prime numbers without prime characters challenge, that was ... ugly as heck.

Sorry to bother you ppl with C again. But can I get help with C code? I have an alt room to talk about it to avoid "noise"

Link to that room?

9:30 PM

in rust, to convert a number from binary u8::from_str_radix(a, 2) isn't enough... it returns a Result, which you have to .unwrap()... painful

Perhaps we should Actually let Rust rust away? Seriously

just no

@2EZ4RTZ Puns R MY territory.

@Zacharý I will take this pun land and make it my pwn

guys Seriously...

9:31 PM

You should integrate Rust into the game Rust and force people to be on a multiplayer server for 30 minutes before they can run their code.

We have become a land of puns a gain.

@TuxCopter Hypocrite! You capitalized Seriously, therefore you meant it as a pun.

@Pavel Everything on stack overflow uses JQuery

@cairdcoinheringaahing you might define a sign to correspond to a letter, not null. If your code has only two distinct signs, your output can also have only two distinct letters (or homoglyphes of letters). I don't know what the longest English with only two distinct letters is, but it's sure not long. Do we misunderstand each other here?

Why does nobody in TNB actually know C enough to debug 20 lines of simple code?

That's offensive, but true.

@2EZ4RTZ The absence of a solution doesn't necessarily mean that no one can help. This just isn't the debugging help room. Please bear that in mind

@Zacharý it'd be more offensive if it wasn't a dead/dying langauge ._.

now that is offensive

10:34 PM

@MagicOctopusUrn That is definitely offensive. C isn't dead in the slightest.

You ninja'd me :(

I ADDED DYING.

C isn't dying, C11 is a thing.

Friggin everything will be npm or the slightly better other web-oriented crap soon enough.

Dying as in my company is phasing it out >_>. Then again we use COBOL for 40% of business.. so wtf do I know

<_> that is not good

Just ask @Adám, his company (Dyalog) still uses it a lot IIRC.

10:36 PM

We use ASP.NET and are phasing out C/C++/VB.NET in favor of accessible web solutions.

@MagicOctopusUrn COBOL. Seriously, COBOL. I'm wondering if anyone still uses Dartmouth flippin' basic.

I mean, yeah it's powerful in terms of math, but in terms of usability, scalability and maintainability... RIP.

@Zacharý oh man, it's not my fault 40% of <some mysterious company's> programs are in COBOL still... When in rome... Learn how to make the romans not be romans anymore...

Um.... nation's ... that makes me wonder who you work for.

Wat. I work for an insurance company... And Nation is in the name. 1 of.. 1 company.

@Zacharý That's right. But more and more of our code is in C++ and APL.

10:38 PM

Huh, I thought Dyalog was implemented in C#.

I expected the APL, obviously. Even ngn is trying to implement more in APL.

@Pavel o_o is that because of the .NET stuff? o_o

@Pavel Dyalog is cross-platform. C# is not.

Yes it is

@Adám So where is all the dotnet stuff coming from?

It's .NET. Just .NET

Well sandboxed my SO post

10:40 PM

The program that you use to build from the command line is called dotnet.exe

So you call it with dotnet build

You're gonna post it to SO? A plz send the codez question?!

SO have a sandbox??

@Pavel Well, which programming language was C# originally written in?

Right...

@Pavel Dyalog APL is one of the official .NET languages listed by Microsoft alongside C#.

Q: Should we start giving constructive criticism when questions are closed?

10:45 PM

Are there docs for Dyalog?

Dyalog's website seems to just link to some books.

WTF would you assume it only means what? :P

WTF is WTF ambiguous? And WTF are you getting these quotes from so fast? -_-

10:50 PM

@Zacharý Just be thankful that Arthur gave you a space between the columns.

@Adám In my defense, the page you linked for me only has pdf download links

Fast? That took over a year...

I mean WTF are you getting these from so quickly?

From the search page

I'm assuming you know that that existed?

10:51 PM

Yes I didn't just search on a whim - it got stars and stuck in the mind :)

@Pavel Excuse me: docs.dyalog.com/#OLH

Fine. All the information is technically there, but it's poorly laid out and hard to find things.

@Pavel Google is your friend. Just search for "dyalog MySearchTerm"…

@Adám Wait how high up are you in dylog?

Does APL on Linux allow .net interop with mono i.e. work on TIO?

@Adám Fair enough

10:56 PM

@2EZ4RTZ I'm not sure how to answer that. There's management/admin, and then Brian (the APL Tools Group leader). I'm in the Tools Group.

I don't think Dyalog has very many employes.

@Pavel I've looked at their "Meet team dyalog" page ... that is so true.

@Pavel No, unfortunately we do not support .NET on non-Windows, yet. We're looking into it though. Right now our priority development of the cross-platform built-in HTML renderer.

There's like 20 people there, that's not really enough for there to be different states of "high up"ness.

@Pavel True: dyalog.com/meet-team-dyalog.htm Very little company providing essential services to very large companies and organizations.

10:59 PM

And it seems (at least to me) that Dyalog has been losing members.

@Zacharý How so?

I am trying to find the SO blog post on SO academy. anyone know the links?

@Zacharý OK, getting off train. Time to bike…

@Adám Why did you have to announce that?

Because it means he's leaving.

TNBing on a bike is kinda hard.

11:04 PM

A simple GTG wouldn't be enough?

@Adám I like trains

though, you did at least possess some taste in flagging a bad pun =P

@2EZ4RTZ Unless there's been a recent change I don't believe there is a way to contact only site mods from chat. From the chatiquette:

> Chat flags are only for urgent or offensive violations of network wide SE policy, and alert all 10K users and mods across all SE chat rooms. Instead mention it to a room owner. If it needs to be private raise a custom flag (in need of moderator intervention) on main (not chat) on one of your own posts.
