Code Golf & Programming Puzzlescodegolf.stackexchange.com

Launched Q&A site for code golfers and for those who interested in code golfing (from beginners to experts), and programming puzzles.

ಠ_ಠ
 
@totallyhuman Wat? The most common co-signup with PPCG was CR‽
 
>_<
That's ... surprising
 
12:43 AM
anyone here use cmder?
 
@Downgoat o/
 
do you know how to add WSL ubuntu to cmder?
 
@Downgoat Yeah, if you make a custom configuration you can specify an executable to use with it. Let me switch to Windows quickly
@Downgoat Ok, so press Win-Alt-p to get to settings and go to Startup->Tasks
Create a new Task with the + icon and name it {bash::wsl} or something.
 
actually I got bash working, how to get zsh working?
I added -c zsh to the command and it still loads bash
 
@Downgoat Go to Bash, echo exec zsh > .bashrc
It's the only good way I can find.
 
1:17 AM
@Pavel can I make right-click not paste
also can I disable the weird background transparenyc
and increase character width
also is there a way to prevent the cursor from flashing
and enable mouse support / scrolling?
 
@Pavel what was that snippet that turned [] bracket style into ][ brackets?
can't find it
nvm found it
hmmm
 
@Adám Both sites were launched at the same time, chances are they were simply the two most active Area 51 entries at that time.
 
@Downgoat I believe your answers are No, Yes, yes, from your zshrc, and no.
 
Anyone want to write Hello, World! in pain flak for 50 rep?
 
Right click being copy/paste is just part of conemu and this is the behaviour you'll get on every Windows terminal. Transparency and character width are in cmder settings. The cursor shape is handled by the application cmder is running. If you don't have mouse scrolling, that means WSL is doing something funky that won't let it work since Cmder supports scrolling by default.
 
1:37 AM
@Pavel I mean like scrolling in vim
 
@Downgoat Oh, Vim mouse support only works with a certain set of terminals, and conemu isn't one of them unfortunatly.
 
I lost the game
 
1:59 AM
@Christopher2EZ4RTZ Are you sure it's even possible?
 
yes
I know it is possible
 
Eh, xkcd?
 
You just lost the game by thinking about it
wait crap
 
@Christopher2EZ4RTZ I still don't understand how Pain-Flak works. The source code > says Unclosed '>' character. Isn't the source code mirrored first?
@Christopher2EZ4RTZ Is it intentional that braceCheck(source) is executed before the source code transformation?
If not, I have a working Hello World.
 
hmmm
@Dennis I can't decide how I want to make it
the source is not mirrored it is run through this:
source2=source2.reverse.tr('[](){}<>','][)(}{><')
 
2:16 AM
Yes, that's mirroring.
 
@Christopher2EZ4RTZ Is that not then tacked onto the end of the original source?
 
@Pavel yeah
@Dennis it does check if it is balanced before the mirror is run
I was planning on keeping it like that but Idk if i should, what do you think?
 
Please make more idiomatic source+=source.reverse.tr(...)
@Christopher2EZ4RTZ Nah, move after.
 
I wouldn't make that decision right now.
 
2:21 AM
I am just adding it so by default it checks after mirror but you can flag with -l to change it back
 
Have yall seen this?
Everything about this angers me so much. 1. It's part of a huge circlejerk that Javascript is awful when this is really not evidence of such because you can do it in any language ...
 
Two words: Operator overloading.
 
2. Everyone keep insisting that this is an absolutely awful interview question and that no one should be expected to know the answer. I'm not an industry expert but to me that seems like something that a) most people should know the answer to if they are familiar with OOP and b) isn't that dissimilar from actual code that might be encountered. </rant>
@Pavel Yeah, I feel like devs should know they can define equals however they wish
 
@Dennis I finished the changes and push the new flag, so by default the code mirrors then brace checks but if -l is used or --hard then braces are checked before and after mirroring
My bounty is going only apply to the -l hello world

2:29 AM
Did I hear something about a bounty having to do with Brain-Flak ...
 
nope@
Pain Flak!
Dennis may push it to TIO tonight if he wants to
 
Which is a Brain-Flak derivative
 
what
can you not hammer reopen?
 
@HeebyJeebyMan sorta
@Dennis I pushed the hello world into the readme
 
There's no 'sorta' to it. It's undoubtetly a brain-flak derivative.
 
2:31 AM
@HeebyJeebyMan here
Has to be run with the -l flag to get the bounty
 
What is the -l?
 
Checks that braces are matched before mirroring code
 
Hah, no problem

I tried but everything broke

and he golfed you
 
I spent far more time than I would have liked finding my old Brain-Flak answer
 
... The parens are unreal
 
lol
I assume dennis is adding pain-flak to tio to claim his rep
 
2:41 AM
@Christopher2EZ4RTZ No he did not.
 
Not yet, anyway.
@Christopher2EZ4RTZ Are you sure you want to keep -l and not make it the default?
 
@Dennis I will swap it
 
2 bytes longer. not hard to shave off
 
Why have a soft mode at all? Isn't it supposed to be a pain?
 
2:44 AM
The soft mode is kind of interesting IMO. But I don't have an opinion.
 
@Dennis ok Pain-Flak is ready to hurt
and DJ floated in and out
I can't tell if dennis is golfing or if he is adding PF to TIO
 
@cairdcoinheringaahing -1 profile still says "i am clearly dog" but your avatar is clearly identicon help stuck in paradox
 
dog == identicon
 
hush
 
it's obviously the only logically valid explanation
 
2:51 AM
that's like saying because "pneumatics" is pronounced like "neumatics", "n" is the same as "pn", and therefore "n" == "pn", and finally "p" == "np"

Riker just solved p=np

To quote XKCD: "This entire think is the quote, not just the part in quote marks." [Quote marks, brackets and editor's note are all in the original. -ED.]
 
3:21 AM
If n==pn, that implies that p==1, but not that p==np :(
(or that one is zero, but that's just nonsense lol)
 
or that n==0
 
Yeah, like I said. Nonsense ;)
 
lol
oh. I thought you were saying that it would imply that 1==0
lol
 
Oh I see the confusion. Not well worded lol
And even with n==0, you can't get to p==np unless p is also zero :/
 
yep
 
3:29 AM
Well the best proof ever presented was busted. I guess the world will never know.

4:30 AM
What's that esolang that's literally just the C preprocessor? IIRC it's yours @pavel
 
Just call it "C preprocessor".
Why do we even need a new name for it?
 
I'm not making it, it already exists, it's called Preproc

bulk?

Anonymous
@Fatalize Usually we say something is available in bulk
 
Anonymous
I can't think of just one word that fits the description
 
Is this "aquire in one instance"? Otherwise amass or stockpile could work.
 
9:19 AM
but amassable and stockpileable don't exist ;_;
I'm gonna have to change my sentence. Thanks

Any word exists if you want it to - dictionaries might disagree, though :P
 
Just use undictionarable words :P

Dictionaries are not definitive sources for what words are in a language - rather, they're our best attempts at listing every word in the language
 
But muh French academy officially accepted words though…
Inventing words feels dirty
 
Good thing not everyone feels that way, or we'd have no words :)
Inventing words is easy. Making them mainstream is harder

and can we use spaces instead of dots or something?
 
@Riker Yeah, it looks fine
 
@AdmBorkBork it's actually said once in teh "further specifications" bit I think
 
@Riker I'm going to say no, because it's about making Triangularity programs valid, which they wouldn't then be
