I wonder if that has false positives from the retina/trash challenge, but if that was the case the script would be pretty bad

quartata

It probably does, honestly :P

Searching for Retina answers is tricky because of that

Martin Büttner

@quartata nope

there are 208 results when searching for retina

quartata

Hm

Martin Büttner

only 38 of those are part of that challenge

You didn't win but you got pretty close

oh I like that

it contains transliteration and a multi-stage loop

Retina, 5 + 3 = 8 bytes + \n . * Every line goes in its own file, so I've added 1 byte for each additional file. Also, the \n should be replaced with an actual newline. Each pair of lines is a pattern-replacement pair. + matches one or more spaces and replaces it with a newline. . matches a...

But not that complicated

@quartata heh, with the latest update I would have beaten Pyth. 23:

@MartinBüttner Interesting

You could add that to the bottom

Oh, geez. There are so many deathclaws around me right now. ;-;

quartata

Retina has really evolved from "simple .NET regex executor" to "crazy thing"

@FlagAsSpam ?

Martin Büttner

@quartata and I still have bigger plans for it ^^

quartata

I saw the decimal to unary thing on your FizzBuzz answer

That's really cool

FlagAsSpam

@quartata Fallout. Bad news bears happening right now.

quartata

@FlagAsSpam Oh.

Never been much of a Fallout person although I do admire the reputation system

Martin Büttner

20:08

@quartata yeah, it's nice I can finally add new syntax to substitutions. the biggest thing that is still on the list is adding some things to the regex flavour that can be done via string manipulation of the regex. (so that I don't have to reimplement the regex engine.) for that I need to tokenise the regex correctly and I'm not looking forward to that.

FlagAsSpam

It's like bad had a evil twin sister in the game and gave birth to the things around me. ;-;

@FlagAsSpam I find this statement highly disturbing ರ_ರ.

Q: Can we standardise how percentage bonuses combine?

Has anyone used SPL before? It seems like a nice crossplatform language. Especially the way it handles (large) constant string literals.

@Mego What's the difference?

@ZachGates It's a lot simpler and loads the images in canvasses rather than a download button

I wonder if this would be fun: a code golf with a larger problem that requires 3 or 4 distinct stages of fairly different nature (some string processing, some arithmetic, whatever). answers can consist of multiple programs (in different languages) and you get pipes between those programs for free.

@quartata Huh?

Martin Büttner

@quartata no, I mean that's fine for a hardcore general-purpose golfing language. I just thought it's something noteworthy that Retina doesn't even try doing.

quartata

@MartinBüttner I know ;)

I don't need to defend Seriously against a DSL regex language. It'll just argue itself into circles anyway.

As opposed to an insane giant mess

@Mego I was just kidding.

Doorknob

@quartata So not all printable ASCII characters are allowed to be in barewords?

Anonymous

@quartata So am I. Except about Retina arguing itself into circles.

quartata

@Doorknob All printable ASCII chars are allowed to be in barewords yes

But I don't consider those commands

Doorknob

quartata

I'm still not sure why you're arguing so vehemently over this. APL's codepage is larger than 127, for instance.

@AlexA. that he does

printable ascii it seems

Alex A.

¯\_(ツ)_/¯

Ain't nothing wrong with that

quartata

Never said there was.

Doorknob

@quartata Achieving the goal of "beat Pyth" is pretty easy when you have access to more characters than it

Alex A.

20:38

I wasn't implying that I thought you said there was

quartata

@Doorknob "beat pyth" = easy

trichoplax

@MartinBüttner I wonder whether it would be better to set up a framework for what counts as free pipes between programs, or just to choose a large enough problem that it is advantageous to mix languages even without defining anything as free

quartata

"beat pyth by at least 40% at all challenges" = hard

And that's my goal.

But it doesn't matter I've given up on it. Jelly's better anyways.

Martin Büttner

@trichoplax the framework would be "the STDOUT of program 1 will be available on STDIN in program 2"

I don't want to split the problem into fixed stages myself

doing that should be part of the challenge

as well as defining an exchange string format that is golfy to generate in program 1 and golfy to parse in program 2

trichoplax

@MartinBüttner That sounds good - I also like not specifying boundaries between parts. Will there be anything to prevent someone just using one language? Or will the problem be chosen such that this is unlikely to be competitive?

@trichoplax well strings for Jelly. don't know what Pyth's weakness is

Alex A.

20:46

Actually, Pyth is pretty long when I write it.

quartata

Jelly is weak at strings, Pyth is weak at number theory.

Both don't have graphical output either.

Alex A.

Pyth does with PPM

quartata

Yeah, but still.

Also I didn't realize Jelly had strings yet at all

quartata

It does.
