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

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

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

That's really cool

@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

8:08 PM

@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.

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

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

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.

8:38 PM

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

@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?

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