@hyper-neutrino how would you sort by string?

hyper-neutrino

@Neil something like x.sort((a, b) => a.toString().localeCompare(b.toString())) or whatever it was

Neil

@hyper-neutrino yeah, but localeCompare is relatively recent and didn't exist when sort was invented

hyper-neutrino

oh

emanresu A

IMO sort should be able to take both monads and dyads

hyper-neutrino

I see

also yes I agree, though if only one is to exist I think taking a comparator is better

you can have comparator-based sorting in Python using built-in sort but only if you create a new class and override the comparison operators

Q: CGAC2022 Day 9: Playing with bits

Part of Code Golf Advent Calendar 2022 event. See the linked meta post for details. The Elves like playing number games. One day, Bin (a friend of Fen) suggests a new game: given a positive integer n, each Elf says a number which has exactly n runs of ones in binary. The first Elf must say the s...

@hyper-neutrino there's functools.cmp_to_key which does that for you

chatgpt thinks mpmath has a polymul function but I don’t see it documented anywhere. Does it just have better versions of the libraries that mere mortals can’t access?

This is totallly surreal “ You are correct, the mpmath library does not have a polymul() function. I must have confused it with the polymul() function from the numpy library. The mpmath library does provide support for polynomial multiplication, but it does not have a dedicated function for this purpose.”

That’s from chatgpt

oh wow

Literally 1984

Yep!

9:32 AM

copilot but unironically free?

mousetail

Ok that pricing page is great

Rare positive bait and switch

emanresu A

One thing that's nice about copilot is its ability to learn new langauges

UndoneStudios

9:57 AM

@mousetail true

mousetail

10:09 AM

Is there a easy way to check if a number is a exact power of some some smaller integer? And get the largest power

Adám

@mousetail I'd take the logarithms of the range, then find the largest integer.

@mousetail Wait, what is the largest power? If I find a few pairs mⁿ, are we looking for the largest m or the largest n?

E.g. 16 is 2⁴ and 4².

mousetail

I'd want 2^4, the largest power

so 8->3, 9->2, 27->3, 16->4 etc.

Thanks, logarithm would work. Though I'll look a bit more if I can find a more efficient way. My numbers are 10-20 digits long

Adám

If you're not golfing, then restrict the search space to √t

emanresu A

Search space can be a fair amount smaller than that - You can only have sqrt, cbrt, 4th root, etc... At some point it becomes optimal to start searching logarithmically

Adám

10:24 AM

{⊃⌽i∩⍵⍟⍨1↓i←⍳⍵-1} in APL.

mousetail

I'm not golfing, so restricting search space makes sense

lyxal

11:41 AM

CMC: Shortest regex to match a string literal which can contain escaped quotation marks (e.g. "abcdef" "this is a \"string\"" should pass, "no closing mark shouldn't)

pxeger

"([^"\\]|\\")*"

assuming no other uses of backslashes

mousetail

You can add |\\\\ to allow backslashes

Ginger

12:23 PM

@lyxal MY GOD

I am 100% making a Klein plugin for that

but,,, like, how tf do they profit???

Adám

Pro services, eventually.

lyxal

@Ginger not yet

@Ginger one very slight tiny problem that we covered last time I found something that was only half free (free for individuals)

closed source

Adám

$5/month: Will use var+=val instead of var=var+val

Ginger

@Adám I'm confused, "pro services" implies that we, the simpleminded nonpaying plebs, don't have some super cool features that the "pros" do have, but that looks like it's offering everything already

@lyxal for [$$!$]'s sake

lyxal

@Ginger might be more advanced features like replit's ai coder has

Adám

12:25 PM

Yes, the Pro features are not yet implemented.

Ginger

@lyxal which you always have to pay for, they kicked me out

I guess I could send them (Codeium) an email and ask them nicely if I could make an extension?

lyxal

you could

but then you also have to implement account authentication to allow users to use the extension

now sure that's just talking with their servers and (probably) storing an authentication key

but that's still something to consider

Ginger

easy, it looks like they can use Google OAuth so I'll just embed a webpage into the extension or smth

lyxal

not all people use Google OAuth with it though

Ginger

how'd'd've'd you logged in with their extension when you installed it?

lyxal

12:29 PM

redirect to their site

Ginger

ok, I can do that

lyxal

and you log in there

Ginger

I'll just do whatever the other extensions do

lyxal

but then it has to open some sort of link back in Klien

Ginger

Klein can open a popup with the site and do minor amounts of trolling to detect when the authentication is done

lyxal

12:31 PM

no no the codeium site opens a link that redirects back to Klein

Ginger

wait does it like ask you "Codeium wants to open a link in VSCode" or smth?

lyxal

it does

Ginger

even easier!

lyxal

codeium.com/vscode_tutorial

Ginger

no tomfoolery needed, just a bit of URI-handling

lyxal

12:32 PM

oh cool

Ginger

oh yeah I can do that easily (kinda)

although if they offer another way I might use that instead

lyxal

well see what they say

Ginger

well I'm not emailing them just yet, seeing as Klein can't do very much right now :p

I'll email them once I have the first beta release out that includes extension support

lyxal

2

Ginger

but you don't because Klein doesn't work yet

that's my point

lyxal

12:35 PM

on a feedback survey on the FAQ page under the heading "Will there be code editors other than VSCode and Jetbrains?"

mathcat

@lyxal Yeah, I program on a klein bottle too.

what even is that

Ginger

I'm 99% sure they'll want a version that at least works before they do anything else

lyxal

@Ginger obviously, but that could be a way to suggest klein if enough people submit responses :p

Ginger

also I'm not sure how much they'll like my requirement to have every plugin be Python and therefore open-source

@mathcat Klein is an IDE I'm working on

as in I created it

mathcat

oh right I remember

Adám

12:38 PM

Hm, I prompted Codeium with // Amend the Array prototype to add ceil and floor methods which map over the Array and it added:

// prototype.
Array.prototype.ceil = function() { return Math.ceil(this.length); };
Array.prototype.floor = function() { return Math.floor(this.length); };

Ginger

It's kinda what you asked for???

Adám

No, I expected

Ginger

well at least if I make a beta account it'll always be free for me :p

Adám

Array  .prototype.ceil=function(){return this.valueOf().map(e=>Math.ceil(e))}

OK, // Amend the Array prototype to add ceil and floor methods which act on each element of the array. worked.

Ginger

hmm, I tried to get it to make a function to iterate over an iterable pairwise and (after importing itertools) the solution it gave me was identical to the top-voted SO answer

at least it saved me looking it up :b

UndoneStudios

1:27 PM

hiya

@Ginger what lang is Klein being built on

Ginger

Python

UndoneStudios

wait a second what is Klein supposed to be? I'm reading transcripts but still don't understand

Ginger

it's an IDE that I'm making

UndoneStudios

for which lang?

Ginger

lots

UndoneStudios

1:31 PM

can I add my own lang to it?

once it's out

Ginger

if you have a language server made for it and you're willing to write the plugin yourself, sure

UndoneStudios

what would open(klein.py, 'w').write("\n# some random lang code here") do?

Ginger

it'd raise a syntax error because you didn't put klein.py in quotes

UndoneStudios

open("klein.py", 'w').write("\n# some random lang code here")?

Ginger

like inside a file being loaded as a language plugin?

UndoneStudios

1:36 PM

yeah

how bout you try it?

Ginger

it'd raise a FileNotFoundError

why are you asking me these questions?

UndoneStudios

cuz... I'd like to see if it's dynamic

Ginger

what?

UndoneStudios

like you can add your own programs

Ginger

...

UndoneStudios

1:38 PM

i mean, langs

Ginger

what are you talking about?

UndoneStudios

mainly trying to do stuff on klein

like... adding your own langs

Ginger

a language plugin doesn't contain the interpreter code, it just tells Klein how to run the interpreter

UndoneStudios

and then putting your own lang open-source

@Ginger ah I see

well also because just now i realised

Ginger

look, once I release Klein I'll include documentation for writing language plugins and then you can use that

@UndoneStudios tell me, what exactly is this language you want to add?

UndoneStudios

1:52 PM

@Ginger something called dterm

Ginger

hmm

UndoneStudios

similar to turtle, but you get control of pixels

and is very... verbose

Ginger

does it (or will it) have a language server? that's a requirement

UndoneStudios

@Ginger not yet

lyxal

@Ginger ooh that'll be nice

UndoneStudios

1:55 PM

besides I just realised

lyxal

Because there's a very distinct lack of clear tutorials on how to make a language server on the Internet

Ginger

@lyxal yeah, the last thing I'm going to do before release is spend a day or two documenting every single public-facing API

UndoneStudios

open("klein.py", 'w').write("\n# some random lang code here") empties klein's source code

before typing the comment

you're lucky it terminated with an error

i should've used mode 'a' rather than 'w'

sorry

... not sorry!

lyxal

@Ginger sounds good to me

UndoneStudios

@Ginger and besides if I have time I'll write a virus too

Ginger

2:04 PM

@UndoneStudios it would... were Klein stored in a single source file that happened to be located in the user's home directory

if you're going to make malicious code at least make it functional malicious code

UndoneStudios

@Ginger doesn't matter

that's a reincarnation of the same code I used to nearly wipe out your IDLE

Ginger

@lyxal I probably won't make a language server writing tutorial :p

UndoneStudios

fear me

Ginger

@UndoneStudios ~~it's hard to fear someone so laughably inept~~

3

lyxal

@Ginger well dang

UndoneStudios

2:06 PM

besides damaging one file damages the entire thing

Ginger

seeing as your "IDLE wipeout code" was so blatantly obvious a baby wouldn't have been fooled, and wouldn't have worked even if I did have the requisite lack of braincells needed to run it

@UndoneStudios except Klein does not have a SINGLE file named klein.py

UndoneStudios

@Ginger similar to IDLE. IDLE uses multiple files, and destroying the center is enough

besides it could also have been __init__.py, so yeah, that's true

@Ginger it will

I have that kind of a mindset

oops did the mods see already?

Ginger

just stop trying, please

UndoneStudios

@Ginger trying to what?

Ginger

be a l337 h4x0r

lyxal

2:10 PM

^

It's unfunny af

mousetail

Try open(__file__,'w'), not only more effective, but much shorter

Ginger

don't give him ideas, we're trying to make him stop

UndoneStudios

~~and besides you think IDLE is everything, and I have enough experience to declare the opposite~~

Ginger

are you off your rocker

mousetail

@Ginger It's equivelent to DDOSing 127.0.0.1

UndoneStudios

2:13 PM

@mousetail too obvious

Ginger

@mousetail oh, I'm stupid lmao

I rescind my previous statement, keep going

UndoneStudios

@Ginger no I'm not, it's that it's just too bad to be a good IDLE

lyxal

I think this conversation has reached a point where continuing it really won't benefit anyone. If y'all want to continue "arguing" for some obscene reason, go to OTTNB.

UndoneStudios

fine I will

Ginger

it wasn't benefiting anyone from the start really, but yea I have better things to do with my time

Radvylf Programs

2:17 PM

@UndoneStudios Maybe consider don'ting

Ginger

send it to OTTNB!

UndoneStudios

@Ginger do it

I mean, @lyxal

where is it?

nah forget it

Ginger

:/

UndoneStudios

what

you wanna continue

I'm fine

but not here

Ginger

just stop, please

UndoneStudios

2:21 PM

fine then

oh wow py3.11.1 released gtg download it

mousetail

py 3.11 has been out for a while already

UndoneStudios

.1

3.11 sucks though

so I hope the bugfix is better

mousetail

Why does it suck?

The performance improvement is great

UndoneStudios

Firstly help terminates with an error if you get the query wrong by accident

that truly seems bad

cuz I'll have to type it again

@mousetail I would have noticed a speedup in my answer to graffe's repdigit question then

mousetail

It's only really noticable in optimized code

UndoneStudios

2:32 PM

besides there aren't a lotta improvements I could use

I could easily port my 3.10 code to 3.11 without a character change

mousetail

Yes, that's the point of a minor version bump. You could run 3.0 code in 3.11 without a change

semver.org

This site explains how it works

UndoneStudios

is that a license or what

Ginger

._.

mousetail

No it's sematic versioning

It explains how versions work

UndoneStudios

@mousetail still looks like a license

mousetail

2:34 PM

In what way does it look like a licence?

Have you ever even read a licencee

UndoneStudios

> a licensee

mousetail

If anything it looks like a RFC

UndoneStudios

am I making a license or what

@mousetail Really Flippin' Cool?

mousetail

RFC

You really need to improve your search engine skills

UndoneStudios

besides if I make a license I would make it a little more fun to read

mousetail

2:36 PM

Why are you even discussion licenses? It has nothing to do with the topic

UndoneStudios

@mousetail what topic?

the 3.11 sucks thingy?

Why does Adobe Reader DC require a subscription just to turn a PDF?

UndoneStudios

2:57 PM

hiya

here to ask a question

what does "exactly n runs of ones in binary" mean?

mousetail

001110 has one run, while 11100001110 has 2

UndoneStudios

like consecutive groups of ones?

mousetail

Yes

UndoneStudios

so 11110011 has 2

right?

oh it does

my bad

can someone fix my IDLE I just updated, for something doesn't seem right:

PyGamer0

Oh huh, there was some snow recently apparently, and some of the skiing seems to be available: onthesnow.com/colorado/telluride/skireport

Guess the altitude makes a bigger difference than I thought, given that it's been like 30° all week here in Texas

user

@RadvylfPrograms I absolutely hate it when a website has a handy feature but they don't actually tell you they have it or document how it works

Like, okay, I've enabled keyboard shortcuts, now what? Do I just mash my keyboard until I find a new shortcut?

Why doesn't the search bar say that it has more advanced features and how do I use them?

They're supposed to be features, not easter eggs
