@DJMcMayhem Do I put that in my vimrc?

DJMcMayhem

12:08 AM

Or in test.vim and source it directly, whichever one is more convenient

Christopher

Being salty that golf-langs are better at code-golf challenges is really annoying

DJMcMayhem

Anyway, the problem I'm running into is that fG and FG should behave the same, but they aren't.

Particularly when ran from the middle of the buffer

Phoenix

@DJMcMayhem IDK how to do that one.

DJMcMayhem

I usually just do :e test.vim and then :w | source %

Phoenix

So what should I test.

DJMcMayhem

12:11 AM

Put a couple lines into a buffer, and then go to the middle of the buffer and see if fG and FG behave the same way

Christopher

Narnia

DJMcMayhem

They should both work as if you pressed VG, but one of them acts like Vggo

Phoenix

fG selects until start, FG selects until bottom.

DJMcMayhem

Ugh. That's what I was getting too

Such a weird bug

@Phoenix Does it also leave your cursor on the same line as you started on?

Phoenix

Yes

DJMcMayhem

12:14 AM

Neovim has the same bug.

Phoenix

Does V?

DJMcMayhem

So I think (not positive) that the issue is the first one sets '[ to 1 and '] to '[ regardless of where you run it from

@Phoenix By extension, yes

It's a vimscript bug, so V has no way around it

@Phoenix If you don't mind me asking, what version of vim are you on? And what OS?

caird coinheringaahing

Ahhhh! Someone please explain "iff" to me! Why 2 "f"s???

ATaco

@Christopher the A just means singular, and I might be able to make that userscript, but I'm not sure how just yet

Phoenix

@cairdcoinheringaahing It's a term meaning "If and only if"

caird coinheringaahing

@Phoenix why?!

Phoenix

What would you rather it be.

It's a clear, concise way if saying it.

caird coinheringaahing

12:36 AM

just plain old "if"

betseg

Writing if and only if is too long, so we write iff instead?

Phoenix

@cairdcoinheringaahing That doesn't mean the same thing though.

if allows for other possible sufficient conditions.

iff specifies a necessary and sufficient condition.

betseg

a if b implies b can be true even if a isn't. a iff b implies b can't be true if a is wrong.

@Dennis Perhaps I worded it confusingly. You get two distinct characters, one of which is !, and you can use as many of each as you need (as long as you use at least one of each). It is possible.

@KritixiLithos Oh btw, I've got some V news (2 different things)

1) I've found out the stupid G, gg issue with the reverse operator. It's a stupid vim bug, ugh

And 2) I've got a new command I'm very excited about. I don't have a name or mnemonic for it, but it'll replace a line with the number of matches of a certain (compressed) regex

Erik the Outgolfer

> (compressed)

compression in V? can't believe it

Kritixi Lithos

number of matches, interesting

DJMcMayhem

4:38 PM

Only regex compression

Erik the Outgolfer

yeah

string compression isn't quite worth it imo...

DJMcMayhem

I've thought about adding it

Kritixi Lithos

that might be useful for unary number manipulation

Like using /../g to perform floor division

DJMcMayhem

@KritixiLithos The biggest thing it'll be useful for is decision-problem. V is terrible at output a Truthy/falsy value

Erik the Outgolfer

how is truthy/falsey defined in V?

DJMcMayhem

4:41 PM

It isn't

There aren't conditionals

Erik the Outgolfer

then you have to add conditionals

DJMcMayhem

Or just go with 0, 1

Erik the Outgolfer

consensus is that it should act like truthy in an if-like construct

DJMcMayhem

The closest thing to Truthy/falsy that V has is non empty line/empty line

@EriktheOutgolfer 0 and 1 works well enough since there is a do n times command

And it's pretty standard

@KritixiLithos Any idea for a mnemonic? Maybe <M-/> since it's related to searching? Probably depends on if we want an uppercase variant or not

Uppercase would probably be replace buffer with number of matches

Kritixi Lithos

@fergusq Hi, I had a look at your mafia implementation in Röda after it appeared in my GH feed. What does the path @http.handle "/cmd/new used for? Is it the path from locahost:port/ or is it the host computer's path? (I don't really understand anything to do with servers and stuff)

@DJMcMayhem then what would lowercase be? replace buffer with matches?

oh wait, it's the difference between buffer and line

lowercase --> line; uppercase --> buffer

That would have to be metagolf obviously, unless there's an easy way to optimize every number

Helka Homba

Is 8 the first number where you can save space? 11^111

DJMcMayhem

@Downgoat :q!

Downgoat

wait what is difference between :q and :tabd

ETHproductions

Yeah, 11*111 isn't worth it

DJMcMayhem

@Downgoat no clue. But q always closes the current buffer

Kritixi Lithos

coincedentally, I opened up a page in my math book that says "what is the best number to choose for the base b?" under the heading "The number e"

Downgoat

@DJMcMayhem oh, I guess tabd keep buffer then

yeah, looks like that is it

base (10 in base (11 in base 2016))

Kritixi Lithos

I said :q 9 minutes ago :P

@ETHproductions Are there any above 8 where you can't save space? (assuming only +-*/^) 11 can be 11*11111+1, 13 can be 111^11+11

ETHproductions

From a brief mental check, no

Helka Homba

congrats unary 7, you are special

ETHproductions

Once you get up to around 20 it seems you can always express it in half the chars (or a little more)

Helka Homba

Though in terms of number of 1's (not counting operators) it's different

7 = 111*11+1 has 8 chars but 6 ones

ETHproductions

Seems like once you get past 5 every number can be expressed with fewer ones

Helka Homba

6:50 PM

yeah

Kritixi Lithos

fun fact: the number of operators will never exceed the number you are expressing

Helka Homba

unless you allow unary + :)

++++++1

ETHproductions

Is that expressing 1 or 7?

Kritixi Lithos

@HelkaHomba "unary" + ":)"? :P

Helka Homba

@ETHproductions 1 as in +(+(+(1))), but my point was more of a joke than really pertinent

ETHproductions

6:53 PM

Heh, clever :P

totallyhuman

downvotes for all

Helka Homba

@KritixiLithos 1:)1 = :D

ETHproductions

So what is 11*1:)1?

Helka Homba

XD

ETHproductions

Perfect XD

CMC: make an esolang out of this
