@DJMcMayhem do you have any CMC in V for me to practice?

DJMcMayhem

2:33 AM

@LeakyNun print this: Try it online!

(the code, not the output)

Leaky Nun

Do we have alphabet?

DJMcMayhem

No, but there is range

oh

<M-,>

in utf?

2:44 AM

@LeakyNun ¬

Leaky Nun

@DJMcMayhem yeah I found it

@DJMcMayhem what is escape?

DJMcMayhem

0x1B

Leaky Nun

How do you reference the count?

14 bytes: ¬ag¬ga6ñÙ7|2x>

Leaky Nun

4:33 AM

@DJMcMayhem how should I do it?

DJMcMayhem

6:13 AM

@LeakyNun Your 14 byte solution seems pretty optimal

Leaky Nun

@DJMcMayhem what is your solution?

I thought there would be a built-in for reversing

DJMcMayhem

Yeah, there isn't yet but I've been working on it recently

Leaky Nun

I see

DJMcMayhem

There's some weird edge cases I'll need to figure out though

But it'll be æ once I add it

Leaky Nun

Do you have another CMC for me?

DJMcMayhem

6:17 AM

I could think of one, but I'm pretty tired right now

Leaky Nun

alright

Kritixi Lithos

7:10 AM

@LeakyNun I have one for you, generate this cross: Try it online!

Leaky Nun

@KritixiLithos thanks

Kritixi Lithos

The code I used to generate this is 31 bytes (or 29 bytes if I had a trailing newline)

Leaky Nun

@KritixiLithos what does « do?

Kritixi Lithos

It increments the count

Leaky Nun

what is the count?

Kritixi Lithos

7:12 AM

So À«é5 would insert argument+1 5s

Leaky Nun

oh

Kritixi Lithos

The count is what is supplied to a command to repeat it x times. So in 5éa, 5 is the count to é. And the program inserts 5 as

btw I got mine to 26/24

Leaky Nun

what is 26/24?

Kritixi Lithos

without trailing newline/with trailing newline

@LeakyNun Are you on Windows?

Leaky Nun

yes

Kritixi Lithos

7:24 AM

Macs are weird, the alt combinations are different.

Leaky Nun

@KritixiLithos would you give me some hints?

Kritixi Lithos

How much do you have so far?

Leaky Nun

9 bytes

is this the right approach?

Kritixi Lithos

@LeakyNun As my math teacher used to say, "There is more than one way to skin a cat".

Leaky Nun

true

Kritixi Lithos

7:35 AM

What I have is much simpler, it first generates the vertical line, and then goes for the horizontal one

Leaky Nun

but I don't see any obvious way

I don't know any vertical commands

Kritixi Lithos

Hint: newlines

Leaky Nun

I could generate a horizontal string and convert it to vertical

Kritixi Lithos

exactly

Leaky Nun

oh heh

how to shift all those lines?

Kritixi Lithos

7:42 AM

All you need to do is to Insert X spaces on every line

Leaky Nun

don't have a shortcut?

Kritixi Lithos

Îcommands performs commands on every line

Leaky Nun

I must be blind

@KritixiLithos Î9> doesn't seem to work

Kritixi Lithos

But Î9>> does

Leaky Nun

why?

Kritixi Lithos

7:48 AM

> is a motion. To indent a line you would use >>.

V autocompletes the second > under certain circumstances

Scratch that

> is a command, it requires a motion as it's argument, like >{motion}.

>> indents the line you are on, but V autocompletes the second > under special circumstances

Leaky Nun

how to delete the whole line including the indentations?

Kritixi Lithos

And because it requires a motion, you can do something like 9>G(or 9>H if you are on last line) to indent everything by 9 spaces

Leaky Nun

interesting

Kritixi Lithos

@LeakyNun So a\nb\nc => a\n\nc or a\nc?

Leaky Nun

never mind

Kritixi Lithos

7:54 AM

okay I am messing up commands and motions

Using 9>H instead of Î9É gives me a bytecount of 24/22

Leaky Nun

28 bytes without trailing newline... ¬09¬80Ùò^ld$ïpòHj9>GHddMpkdd

I have much to learn

Kritixi Lithos

You can change the dd to just d because V autocompletes the d since it is at the end of the program

d$ = D

Leaky Nun

are there registers?

Kritixi Lithos

Yes, in both Vim and V

Leaky Nun

not the temporary register created by dd etc

Kritixi Lithos

7:59 AM

You can store stuff into registers

Leaky Nun

how?

Kritixi Lithos

"{register}{command}{motion}. For example, "aY copies the current line into register a

"*Y copies the current line into the clipboard

"kdj deletes this line and the line below and stores it into register k

Leaky Nun

it doesn't save much bytecount...

25 bytes: ¬09¬80"kYò^lDïpò9>HMdd"kP

at least I out-golfed you :p

Kritixi Lithos

8 mins ago, by Kritixi Lithos

Using 9>H instead of Î9É gives me a bytecount of 24/22

Leaky Nun

never mind

Kritixi Lithos

8:05 AM

I got yours to 24:

¬09¬80Ùòlé
òHj9>GHddMpkd

Leaky Nun

oh..... that is clever

I always thought of it as 2D

I also have this for 24 bytes:

¬09¬80"kY^òlé
ò9>HMdd"kP

Do you have any more hint?

Kritixi Lithos

20 bytes:

¬09¬80Y^òlé
ò9>HMPjd

Leaky Nun

oh that's nice

Kritixi Lithos

Now you golfed me :)

Leaky Nun

now there's one language you're better than me at :p

Kritixi Lithos

8:10 AM

My solution is:

¬08¬80YÓ./&\r
9>HMPãá9

Leaky Nun

I hate regex :p

Kritixi Lithos

(add a Gd to remove the trailing newline)

Leaky Nun

is that regex?

Kritixi Lithos

Indeed

Ó./&\r: on this line, replace every character with itself and a newline

Our solutions are very identical

@LeakyNun I'll bet DJ will come here and golf us both :P

Leaky Nun

anymore challenge?

Kritixi Lithos

8:14 AM

Why not try one of your challenges: codegolf.stackexchange.com/q/86986/41805 (note: there is both a Vim and V answer to the challenge)

Leaky Nun

alright, I won't peek

Kritixi Lithos

But today's V can beat that V (because of new functions)

Leaky Nun

11 bytes: ¬AZ25ñÙx$pñ

let's see the solution...

36 bytes... nvm

oh, the method is the same lol

and I don't even need the final ñ

Kritixi Lithos

^

Leaky Nun

Alternative 10 bytes: ¬AZ25ñÙlDP

anymore challenge?

Kritixi Lithos

8:20 AM

Do you want a mega-challenge (also on PPCG)?

Leaky Nun

depends on what that challenge is

namely, string manipulation is good

Kritixi Lithos

V was the only language to beat Bubblegum in that challenge (and it won)

Leaky Nun

don't expect me to do arithmetics

@KritixiLithos which challenge?

Kritixi Lithos

109

Q: A keyboard so real you can almost TASTE it

... Not that you would, would you? The task is simple, output the following text: ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ________ ||` |||1 |||2 |||3 |||4 |||5 |||6 |||7 |||8 |||9 |||0 |||- |||= |||BS || ||__|||__|||__|||__|||__|||__|||__|||__|||__|||__|||__|||__|||...

Leaky Nun

looks complicated...

Kritixi Lithos

8:21 AM

The V answer also won two bounties

Leaky Nun

my userscript says 149 bytes...

let's move on :p

I think the room description should include vimgolf.com

Kritixi Lithos

oh yeah, that's a nice website

Leaky Nun

let's do this

(transform the input to the code)

Kritixi Lithos

Trailing newlines allowed?

Leaky Nun

I don't think it is allowed

Kritixi Lithos

8:32 AM

12 bytes: 2dd3gJ$xÍ,/ò

Badly golfed

Leaky Nun

I see

Kritixi Lithos

What do you have?

Leaky Nun

not really anything lol

Kritixi Lithos

CMC: output this

a
 b
  c
   d
    e
...

Up to z

Leaky Nun

thanks

Kritixi Lithos

8:47 AM

and obviously, trailing spaces on each line and a trailing newline are allowed

Leaky Nun

16 bytes: ¬az25ñÙlhr ñÎ^lD

I feel like this is too long

13 bytes:

¬az^òlé
òÎj>G

@KritixiLithos how long is your solution?

Kritixi Lithos

9:04 AM

I haven't started on it yet

That's a nice solution

Leaky Nun

@KritixiLithos CMC: all prefixes of input

my solution is 5 bytes

from passwordsgenerator.net/sha512-hash-generator

Kritixi Lithos

What do you mean by that?

Could you give an example?

Leaky Nun

Hello, world!
Hello, world
Hello, worl
Hello, wor
Hello, wo
Hello, w
Hello,
Hello,
Hello
Hell
Hel
He
H

For input Hello, world!

Kritixi Lithos

@LeakyNun that's mine as well :P

lol

Leaky Nun

nice

@KritixiLithos let's do this

nah I'm just kidding

Q: This is my pillow

...will you help me immortalize it? I've had this pillow a few years now, and apparently it's time to get rid of it. Can you please write a function or program, that I can bring with me and use to recreate this pillow whenever I want to reminisce a bit. It must work with no input arguments. ...

code-golf ascii-art kolmogorov-complexity

Let's do this

Kritixi Lithos

9:21 AM

all right

Leaky Nun

20 bytes

Kritixi Lithos

27 bytes, yikes

26 now

5é/5á\|6ä$4ÙGd5l$p3ÙGVHy2P

Leaky Nun

9:38 AM

way to go

Kritixi Lithos

It's still 26 bytes

How did you approach it?

Leaky Nun

hint: rotation

Kritixi Lithos

I'm still puzzled, rotate what and how?

Leaky Nun

so I created the entire first line in the first 10 bytes or so

then duplicate -> rotate -> duplicate -> rotate -> etc.

Kritixi Lithos

Do you mean this: Try it online!?

Leaky Nun

9:46 AM

something similar

Kritixi Lithos

22 bytes now

What's your solution?

Leaky Nun

6ñ5á/5á\ñ6ñ4ÙG5x$pñd

Kritixi Lithos

Ah, 5x instead. For some reason, I thought 5x would not work

that's nice

DJMcMayhem

10:18 AM

@KritixiLithos 2dd --> dj

(and not just cause I'm narcissistic and put my name into code :P)

Kritixi Lithos

lol

DJMcMayhem

@LeakyNun IMO, I would consider that a bug. (Although I do understand exactly why it happens)

@KritixiLithos can you see any potential downsides mapping î to ç^/?

Kritixi Lithos

Don't you mean Î instead?

DJMcMayhem

Î

Ah, code block changes it

Yes, that's the same

Kritixi Lithos

The commands after ç^/ get interpreted as normal commands, right?

DJMcMayhem

10:23 AM

Yes, but they operate slightly differently

Kritixi Lithos

How exactly?

DJMcMayhem

For example, :%norm Yp (which is Î) creates a bunch of copies of the first line, but :g/^/norm Yp (which is ç) duplicates every line

ç it's definitely the more convenient of the two

Kritixi Lithos

In this case, I think ç is more useful

ninja'd

DJMcMayhem

Yeah, I'll look into changing that tomorrow. That'll also fix leakys bug

I'd also like to add a motion for in the current line

So doing ä<whatever> would be like |ä$

Ok, it's 4:30 AM, I should not be awake xP

Good night everyone

Kritixi Lithos

o/

Leaky Nun

12:48 PM

@KritixiLithos any CMC?

Kritixi Lithos

not yet

Leaky Nun

@KritixiLithos this isn't my challenge lmao

Kritixi Lithos

oh lol, I didn't realise that

Leaky Nun

1:11 PM

@KritixiLithos do you think we can make the diagonal alphabet challenge on main?

Leaky Nun

2:26 PM

òlé
òòddPgJkj

Try it online!

@KritixiLithos @DJMcMayhem \o/

DJMcMayhem

5:25 PM

@LeakyNun I think it would a good challenge. (And I've got a 14 byte solution)

Leaky Nun

@DJMcMayhem scroll up to see my 13-byte solution

I out-golfed the creator yet again :p

DJMcMayhem

Well damn

Leaky Nun

what is your solution?

DJMcMayhem

¬azÓ./&ò
Hòj>G

Leaky Nun

we share the j>G component \o/

what does `ò
Hò` do?

DJMcMayhem

5:31 PM

@LeakyNun Down to 12 bytes now

Leaky Nun

:o

DJMcMayhem

@LeakyNun The first one is part of the regex, not a recursive command

Leaky Nun

and the second one?

DJMcMayhem

It says Replace each occurrence of any character with that character followed by a newline

@LeakyNun The second one is a recursive command

Leaky Nun

why do we need a recursive command?

9 hours ago, by Leaky Nun

¬az^òlé
òÎj>G

DJMcMayhem

5:33 PM

Either one is fine

Do you know what the recursive command does?

Leaky Nun

I see

@DJMcMayhem I know

DJMcMayhem

So then

¬azÓ./&ò
Îj>G

Is another valid one (13)

regex :o

@LeakyNun 11 now. :)

whaaaat

5:34 PM

Would you like to see it?

Leaky Nun

give me a few minutes

DJMcMayhem

OK

Ping me if you want to see it

Kritixi Lithos

Wait for me

Leaky Nun

alright

@DJMcMayhem regex cant match empty strings :/

DJMcMayhem

I'll give you a hint though. Since ¬az puts the cursor at the end of the line, all of our solutions so far require going to the start of the line before modifying the buffer. This one does not

@LeakyNun What do you mean? Yes it can

Leaky Nun

5:36 PM

@DJMcMayhem ¬azÓ/ò doesn't work as intended

DJMcMayhem

Oh yeah, not like that

Kritixi Lithos

I got a 12-byter that goes z to a
