@Lembik did you read my message?

What a good icon to indicate "reaction" or "quick reflexes"?

Lembik

@LeakyNun about the time until the bounty ends?

Leaky Nun

@Lembik yes

Lembik

@LeakyNun We could improve the question

Leaky Nun

edit it howsoever thou willest

@HelkaHomba Lightning bolt

Lembik

9:48 AM

It should link to the coding question Arthur posed, and copy some of the examples over

Helka Homba

@Mego ooh, yes, thanks

Lembik

I don't have time today sadly @LeakyNun

CMC: animate a rotating fan, each iteration is shown separated by newline here:

Jim

@isaacg What was the reason that prevented you from using characters in the range [128, 255] for Pyth? Like éçëà«

Kritixi Lithos

each iteration of the rotation takes 1 second long

Is Science the knowledge of what is around us? Please give your opinion. I request you.

Jim

@isaacg Also, do you still add features to Pyth?

@Arjun Ono. Not this again

Kritixi Lithos

no that's a bad challenge, too much hardcoding

Arjun

@Jim Have you changed your username recently?

Jim

@Arjun No, I just remembered exactly what someone else told last time you started talking about philosophical stuff.

Mayube

@Jim what would that be?

Leaky Nun

9:59 AM

@Jim what features do you want?

Arjun

@Jim Oh okay.

Jim

@Mayube "Ono. Not this again"

@LeakyNun It's not "the features I want", I just want to know if there is still room for improving Pyth

isaacg

@Jim I wanted Pyth to be always typable, so I restricted it to printable ASCII. The most recent feature I added was a default function effect for arity 1 functions, added June 5.

To all those who use Pyth: I've finished my semester, and I'll be implementing issues and new features.

Leaky Nun

@isaacg what causes the double backslash error?

github.com/isaacg1/pyth/issues/211

isaacg

10:03 AM

Pyth's online interpreter blacklists lots of stuff to prevent hacking. Unfortunately, it's a little overzealous.

Jim

@isaacg And is there an official place where to make suggestions?

Leaky Nun

@isaacg but it works in other location

Jim

Other than making pull requests

Leaky Nun

just not the third argument of replace

@Jim issues

isaacg

github.com/isaacg1/pyth Create an issue

Leaky Nun

10:04 AM

github.com/isaacg1/pyth/issues/new

Jim

@isaacg Okay. Actually I filled an issue once already for Pyth :)

isaacg

@LeakyNun All I know is that it works offline, and fails offline in safe mode (-s).

Arjun

@Mego What was Be Nice, people. for?

isaacg

-s does nothing more than impose the blacklist.

Anonymous

@Arjun People weren't being nice to each other.

Leaky Nun

10:07 AM

@isaacg and what is the blacklist?

Anonymous

@Arjun If you don't see it, then there's no reason to bring it back up.

:38421176 please don't delete messages after they're replied to...it disrupts conversation flow

Leaky Nun

CMC: highest digit (digit in the highest position) (for god's sake, when did highest digit mean biggest digit?)

restriction: you must take in an integer if your language allows it

Erik the Outgolfer

@LeakyNun Jelly, 2 bytes (full program): ṾḢ

Anonymous

@LeakyNun Actually, 2 bytes: $F

Erik the Outgolfer

10:12 AM

or 3 bytes if function: ṾḢV

or...Jelly, 2 bytes: DḢ

^ = both program and function

Jim

@LeakyNun Pyth, 2 bytes: h`

Leaky Nun

@Jim h`

Jim

@LeakyNun Disturbing, eh?

Leaky Nun

rip formatting

Anonymous

Yeah good luck with trying to escape a single backtick

Anonymous

10:15 AM

I think `h``` works

Leaky Nun

done

Urgh

totallyhuman

@Dennis derp sorry

Anonymous

At least chat formatting sucks slightly less than comment formatting

isaacg

@LeakyNun The one causing the issue is this one: github.com/isaacg1/pyth/blob/master/pyth.py#L751 removing imports. Imports can have too much power, like importing os, so they're disallowed.

Leaky Nun

10:19 AM

@isaacg I don't see how that causes the issue

Kritixi Lithos

@LeakyNun what does that mean?

isaacg

Me neither, but that's the error message.

Kritixi Lithos

the first digit

I take it

Leaky Nun

yes

Kritixi Lithos

that'd be a not bad challenge

A: Sandbox for Proposed Challenges

Deep-dichotomize a list Given a list, dichotomize it, then dichotomize both resulting sublists, etc., until you reach sublists of length 1. For example, given [1,2,3,4,5,6,7,8]: Dichotomize: [[1,2,3,4],[5,6,7,8]] Map dichotomize: [[[1,2],[3,4]],[[5,6],[7,8]]] Map map dichotomize: [[[[1],...

isaacg

Too trivial for my taste

Erik the Outgolfer

yeah too trivial for main

Anonymous

@KritixiLithos Every solution would be of the form n.toString()[0]

Kritixi Lithos

>_< I did not see that coming for some reason

Erik the Outgolfer

maybe if we disallow indexing...but then it'd be do x without y

Kritixi Lithos

10:24 AM

~~I just want to answer a challenge to get enough rep to get back to my position in the leaderboard, especially with ErikTheOutgolfer catching up~~

Erik the Outgolfer

and then it'd again be python 2 lambda x:x/10**~-len(`x`)

Jim

@isaacg In Pyth how would you decompose an integer in a list of its digits? Other than msd` ?

isaacg

j ... T

Jim

@isaacg Whoa, finally I got a shorter version!

For the time I searched for it…

Erik the Outgolfer

jbT would be convert to base 10...but often there are other ways to cleverly manipulate with digits

assuming variable is b

Jim

10:26 AM

@EriktheOutgolfer Yeah, I've looked into the doc

Erik the Outgolfer

unless you have set T to something, in which case it'd be either jb10 or sM`b (latter is preferred because no leading or trailing digit)

former would have golfability issues in e.g. +j 123456 10 7

Jim

@EriktheOutgolfer I don't understand what you mean by "no leading or trailing digit". The perk I see is that you can omit the variable in the latter version (for implicit input)

Erik the Outgolfer

@Jim see ^^

isaacg

@EriktheOutgolfer You could use h9 instead of 10 to half-solve it.

Erik the Outgolfer

the latter would be shorter: +sM`123456 7

Jim

10:30 AM

@EriktheOutgolfer Got it

isaacg

Also remember that if T is your lambda variable, you can use ; to mean 10.

For instance, f}TjQ;

Erik the Outgolfer

@isaacg I'm talking about the case you have set T to something yourself, with =..T

isaacg

Yeah, that comes up too.

Jim

@isaacg I remember having hard times before I knew this trick. Like: "Oh no, I cannot use k because I'm in .e…"

isaacg

That's why I added it.

Erik the Outgolfer

10:35 AM

of course the ; case would only be useful for f

btw how does Pyth still beat Jelly et al. sometimes? I just don't get it...

especially if you need .n0 (3 bytes) for a single constant

Q: Change text from string input

Try to come up with something that replaces a random text with the given text below. Make it in Python or Java Doesnt matter how long the code is It has to replace all the text with the given simbols and code Ex: "I play pokemon go" or "i p l a y p o k e m o n g o" Outcome: "△⟓◪G⃞⟓ X/P⏂♓︎O...

string

isaacg

@EriktheOutgolfer Pyth and Jelly are just good at different stuff. When Pyth can make all its variables implicit and Jelly has to use separator characters, for instance.

Erik the Outgolfer

@isaacg not exactly...Jelly also has implicit variables, but it's tacit not polish

isaacg

That's what I meant

The tacit system sometimes needs separator characters.

Erik the Outgolfer

sometimes you would need ⁸⁹ to represent left/right arguments, and rarely you'd also need spaces

Maybe somebody should make an alternative to PHP, that's just PHP with all the shit removed, and call it OGO
