Wheat Wizard

That regex provided in the comic is not the shortest

Kritixi Lithos

TNB!

Mayube

@KritixiLithos there's a space before ` [TN]`

@WheatWizard it's not about length

Wheat Wizard

What's it about then? alf.nu/RegexGolf is about length

Kritixi Lithos

4:06 PM

@WheatWizard oh gosh, people hacked the site

*hacked the scores

ETHproductions

What the heck with the usernames

Wheat Wizard

Or they are just really god

Mayube

nah

I don't know regex but I know javascript bitches

they're putting JS into the comments to change their score :D

Q: Output a string 1.5 times the length of the code

Create a code that outputs a string 1.5 times as long as the code itself. This is based off of the 'Output with the same length as the code' challenge, but I feel like this would be a bit more challenging. If rounding is needed, always round up. Standard golfing rules apply. Best code wins? This...

Kritixi Lithos

I'm trying to figure out how exactly they changed their scores

Wheat Wizard

4:10 PM

I want to change my score to 2, no one has scored 2 yet therefor its better than 1

Mayube

CMC: Write a regex that will match any string that does not contain 2 repeated letters adjacent to eachother (eg the ts in letters)

/^((.)(?!\2))+$/

/^(?!.*(.)\1)/

Oh, that's clever

User 1: gibberish. User 2: gibberish. User 1: "oh that's clever"

Kritixi Lithos

4:13 PM

why do you need the .* and the ^?

Leaky Nun

@Okx it is code golf now

@KritixiLithos without the .* it will only check the first two letters; without ^ it will match after the repeated letters

ETHproductions

I suppose if you really wanted you could do /(.)\1/ and negate the result :P

Mayube

K well, let's see you beat this one

CMC: Write a regex that will match only strings of a prime length

Leaky Nun

@Mayube that's quite standard

Christian

@PhiNotPi Assuming you aren't just making a joke about how regex looks like gibberish, regex is a super useful skill to have and I suggest taking some time to learn how it works :)

Mayube

4:15 PM

oh ._.

Leaky Nun

@Mayube /^(?!(..+)\1+$)/

ETHproductions

Actually it's only standard if all chars are the same. I don't know if it's possible if the chars can be different

Leaky Nun

@ETHproductions oh, right...

I think you can only do it with balancing groups if the chars can be different

Mayube

fair enough then, what about one that only matches strings in alphabetical order?

Leaky Nun

@Mayube /^a?b?c?d?e?f?g?h?i?j?k?l?m?n?o?p?q?r?s?t?u?v?w?x?y?z?$/

Mayube

4:17 PM

is that as short as it gets?

ETHproductions

Regex can't do comparison :P

Other than equality, of course

Erik the Outgolfer

equality is what regex is built to do :P

Kritixi Lithos

@LeakyNun s/\?/*/g

Erik the Outgolfer

ninja'd

Mayube

@LeakyNun wait that wouldn't work, it'd match the an in analyse, and if you enclose it in ^$, it wouldn't match something like access, I think you need asterisks not question marks

Leaky Nun

4:19 PM

I don't know if the order is strict

Kritixi Lithos

or y/\?/*/ if you are using sed

Christian

What is meant by "chameleon challenge"?

Leaky Nun

@Christian challenge that changes

Okx

Does anyone know why this post is a different shade to the others? puu.sh/wi4lV/b1da100b9f.png (I turned off the user-script before, that doesn't fix it)

Christian

@LeakyNun You mean like the OP edits the challenge?

Leaky Nun

4:21 PM

@Christian yes

@EriktheOutgolfer in case you still don't see what I mean... look at the answers that are posted there

Erik the Outgolfer

I totally get what you mean if it's what I think you mean

Phoenix

WTF, my terminal randomly changed from []pavel@localhost ~]$ to [pavel@matthew-sphone ~]$

How the hell did that happen

Leaky Nun

@EriktheOutgolfer deduce what happened then.

Phoenix

I am incredibly confused right now

The terminal window still says pavel@localhost

Kritixi Lithos

@Phoenix haxors

DJMcMayhem

4:25 PM

@Phoenix is your name Matthew?

Leaky Nun

@Christian did you request access to the wrong room?

no

Weird

@Phoenix hacked

ninja'd

4:26 PM

@LeakyNun No? The Jelly one?

Leaky Nun

@Christian alright.

Phoenix

ლ(ಠ益ಠლ)

Kritixi Lithos

quick, turn off your wifi

Shaggy

4:44 PM

@KritixiLithos Wait, did everyone just turn off their WiFi? It's gone awful quiet in here!

ETHproductions

@Shaggy What did you say? I can't hear you over the sound of people screaming that the wifi is shut off

Phoenix

I think this is the first time I've used ლ(ಠ益ಠლ) in the commands tacoscript

@EriktheOutgolfer What exactly is a chameleon challenge?

A: Sandbox for Proposed Challenges

@Christian challenge that changes

user165474

4:55 PM

Oh okay.

user165474

So like all those challenges that should have been sandbox that keep changing specs because the original was too bad?

Erik the Outgolfer

yeah...that's why I use the sandbox even though I'm sure my challenge doesn't need it

user165474

Ah okay. Yeah I might want to more because I skip the sandbox for some challenges I'm sure are fine. Almost all of the time I judged right (in fact now that I have more experience I hardly judge incorrectly)

user165474

but I had quite a few closed and deleted challenges when I was new here which is partly why it took me so long to get "curious"

Erik the Outgolfer

I'd advise to just to be on the safe side

btw I don't have curious yet

basically bad history

user165474

4:57 PM

Ah okay.

user165474

Yeah pretty much same for me.

user165474

So like I just got curious yesterday and I am close to getting the silver (Inquisitive)

Anonymous

@EriktheOutgolfer That's incorrect. This defines what a chameleon challenge is.

Anonymous

A chameleon challenge is ostensibly about one thing, but additional requirements (cumbersome I/O format, bonuses, error handling, etc.) overshadow the core challenge

user165474

Also did you get an answer about the shower temperature yet? I also have rep on Code Review apparently

Erik the Outgolfer

5:00 PM

yeah same as me

Leaky Nun

@Mego so I propagated a wrong definition.

Erik the Outgolfer

hence "Leaky's definition"...basically more like "what we were talking about" rather than "accurate fact"

Anonymous

@HyperNeutrino 20*N degrees Celcius, where N is the amount of rep

user165474

Including association bonus?

Erik the Outgolfer

btw why does Dennis get stars for starbait >_>

@HyperNeutrino No

@EriktheOutgolfer How is complaining about autocorrect starbait?

user165474

Phew. That would be 2620 for me then D:

user165474

Well now it's still 620 C

Phoenix

@Phoenix Update: terminal window name has also changed its name to pavel@matthew-sphone: ~

5:04 PM

if I don't show up ever again expect that I died from 620 C showers

Anonymous

@EriktheOutgolfer That did not answer my question even slightly

Erik the Outgolfer

first of all that wasn't even autocorrect...

Anonymous

@HyperNeutrino That's just under the ignition temperature of natural gas (659 C)

Anonymous

@EriktheOutgolfer It looked like a combination of autocorrect and mobile chat's propensity for sending duplicate messages

Anonymous

I have 10 non-bonus rep on CR, so I get a 200 Celsius shower (a bit above the ignition temperature of paper)

lucky you I get 600C

user165474

@Mego Oh gosh D:
