@Lynn Oh, cool. <C-v> would be better though. Too bad it's unprintable

DJMcMayhem

It would also be really hard to get " and : with that approach

@LeakyNun wat is this python black magic

Leaky Nun

@TùxCräftîñg in math notation: ((a-1)%b)+1

DJMcMayhem

3:02 PM

@LeakyNun ooh, that's clever

Leaky Nun

@DJMcMayhem I thought that is what you have in mind

DJMcMayhem

It is, I just wasn't sure how to implement it

TùxCräftîñg

this is still black magic O_O

Lynn

@DJMcMayhem You also have @= I guess. Without = is tricky though (I assume that’s what you mean)

DJMcMayhem

@TùxCräftîñg think about it. 6 - 1 is 5, 5 % 3 is 2, 2 + 1 is 3

TùxCräftîñg

3:04 PM

clever

Leaky Nun

@TùxCräftîñg Think about it this way:

1%3 = 1
2%3 = 2
3%3 = 3
4%3 = 1
5%3 = 2
6%3 = 3
7%3 = 1
8%3 = 2
9%3 = 3

DJMcMayhem

@Lynn I'm actually unfamiliar with @=. What exactly does it do?

Leaky Nun

So you effectively shifted the residue set

Lynn

Run an expression as a macro

See :help @=

DJMcMayhem

You could do :h<cr>10jfahylZZp for equals.

Q: Tips for golfing in vim

I've recently realized how vim works great for golfing, especially for kolmogorov-complexity. Also, according to meta vim is a perfectly acceptable 'programming language' at least, for the scope of this site, that is. What general tips do you have for golfing in Vim? I'm looking for ideas which ...

Lynn

Nice idea. :h5↵kylZZp is even shorter

english golf CMC: how to golf "there were no"

DJMcMayhem

3:16 PM

@Downgoat There weren't

Releasing Helium Nuclei

@DJMcMayhem there weren't any

longer than "there were no"

DJMcMayhem

Or if you don't have to be perfectly grammatical "weren't"

Downgoat

@DJMcMayhem removing contraction, still same amount of woreds

and you'd need to add an "any" so its 3-4 words

Oh BTW @Downgoat did you hear about vim 8 coming out? Super exciting.

It's practically neovim

:O rly

@Downgoat ain't no

too informal :P

@LeakyNun Not me

@Lynn well firstly how do I construct a character without using Ọ :o

DJMcMayhem

3:22 PM

@Downgoat I'm on 7.4.2000+ so I'll barely notice a difference, but it adds some sane defaults (like dropping default compatible), drops support for some super old systems, and add asynchronous support. As well as some new keystroke combos.

@Downgoat you mean "q"?

Thanks for your attention

DJMcMayhem

@Downgoat That's weird, it works fine for me though I don't use very often. Are you on terminal or macvim?

Downgoat

terminal

zyabin101

I just watched 30 minutes of chat in time lapse. :3

DJMcMayhem

@Downgoat you should definitely get macvim. Although I suppose it's not really worth it if you just use neovim anyway

zyabin101

@Downgoat Nope? They are a decent idea?

Downgoat

3:27 PM

@DJMcMayhem mac terminal works perfectly fine. idk why macvim would be better

DJMcMayhem

@Downgoat out of curiosity, what do you see when you type i<M-a><esc>ga?

So, can I use the library for participating in challenges and what is required for that?

@zyabin101 i strongly don't reccomend using golfing lib. It's gonna get less upvotes than python because people don't understand it, and less upvotes than golfing lang because syntax still isn't short enough

4:35 PM

;-;

feersum

@Sp3000 We lucked out again. Maybe the short answer would be obvious if I had any idea what "CM12" is supposed to be counting, but there didn't seem to be any explanation on OEIS.

Downgoat

generic name suggestions pls?

Sp3000

As far as I could tell, CM(1,2) is a generalisation of the Catalan numbers defined in terms of generating functions, the link to which I've since lost

But somehow I dunno how relevant that is :P

feersum

In what way is it a generalization?

How is it at all related to Catalan numbers?

Catalan numbers have a clear interpretation in terms of balanced parenthesis sequences.

So I would want to see something like, the generalization counts, for example, the number of sequences using 2 kinds of barckets.

ΛεγίωνΜάμμαλϠΨΠʹ

Anyone here have a decreasing function from natural numbers to natural numbers?

(decreasing as in f(n) < n)

feersum

4:41 PM

f(0) < 0 seems tough.

Sp3000

citeseerx.ist.psu.edu/viewdoc/…

I think this was the one, with the c(x;a) definition

oeis.org/A064062 is the relevant sequence, and I'm sure you could come up with some parenthesis equivalent, based on the "Dyck n-paths" comment

ΛεγίωνΜάμμαλϠΨΠʹ

Okay, so f(1) ~~= 1~~ can be whatever and for n > 1, f(n) < n

Downgoat

question: are short-circut ops left-associative or right-associatitive

feersum

@Sp3000 So that's a good explanation of the diagonal at least.

Leaky Nun

What does "your favourite sport" in anagol mean?
