What would be the best way of trimming trailing lines that only contain whitespace?

fwiw I'm trying out codegolf.stackexchange.com/questions/109995/…

DJMcMayhem

@KritixiLithos What exactly do you mean? You can always do ÇÓ/d but I'm not sure that's exactly what you want

Kritixi Lithos

@DJMcMayhem Ah thanks, that's what I needed :)

DJMcMayhem

Oh, great. :)

That solution is really nice because doubly negating it is much shorter then the obvious approach ç^ó*$/d

DJMcMayhem

07:45

That awesome moment when you outgolf MATL by 5 bytes :)

Kritixi Lithos

:D

How does \z work?

DJMcMayhem

Oh, it's extremely useful.

\ze and \zs include/exclude parts of the matched pattern from the substitution

So :s/\d\zs\d will remove every second number

Kritixi Lithos

ooh

DJMcMayhem

And :s/\d\ze\d will remove every first number

And :s/\d\zs\d\ze\d will remove every middle number of three (so "123456" --> "1346")

Kritixi Lithos

Then how did you get the input e into the regex?

DJMcMayhem

07:53

<C-r>a

Kritixi Lithos

Ah, the argument is stored inside the a register

DJMcMayhem

Ugh, It's getting really late, and I'm running on 3 hours of sleep. :/

G'night

Kritixi Lithos

Cya

Kritixi Lithos

Now that I'm looking closer at your submission, you didn't have a newline after the replacement. How does that work?

DJMcMayhem

16:55

@KritixiLithos One of the features in proudest of :) The macro implicitly ends any command

Kritixi Lithos

17:37

Amazing! I think I can use this to golf my submission down further :)

DJMcMayhem

18:07

The cool thing about it is that it even applies several layers deep. For example, òçfoo/dd<CR>ò the carriage return and second d would both be filled in. And if it's at the end of the program, the ò would be too

Or another cool example is the 6th line of my keyboard answer: ç^/Ùòf T|v,r_

The ò is filled in by the end of the ç command

Kritixi Lithos

I have to say, pretty neat

Riker

@DJMcMayhem opinion on vim w/ gui?

DJMcMayhem

@Riker I use Windows, so IMO absolutely essential.

Riker

?

why?

DJMcMayhem

Cmd sucks and I'm too lazy to install conemu or something like that

Riker

18:11

ah

that makes sense lol

DJMcMayhem

It sucks slightly less on 10, but I frequently use 10 and 7

Riker

lol

DJMcMayhem

Although even though I use gvim, I always do :set guioptions=

Riker

?

wat that do

Kritixi Lithos

Did you intentionally leave out what comes after the =, or is it supposed to look like that?

Riker

18:14

I think it's intentional

DJMcMayhem

Yeah, that was on purpose. In English "set guioptions = nothing"

Riker

ninja'ed

but why?

DJMcMayhem

Just a sec, it's easier to show than tell

Riker

kk

DJMcMayhem

@Riker Default gvim:

With :set guioptions= :

s/defualt/default but with most of my settings and colorschemes

Riker

18:18

ahhh

so you use gvim so you don't have to use vim in a terminal

and you turn off the rest of the GUI options

DJMcMayhem

Yeah, but I still use it like vim, so no mouse, no GUI options, lots of :! command line stuff, etc.

Actually, not no mouse, but I generally avoid it

I still have :set mouse=all

Kritixi Lithos

Then what is the difference when using normal vim and gvim without the GUI options?

DJMcMayhem

Normal vim is crippled by whatever terminal you happen to be using. If you have a sucky terminal, vim has to suck because it has no other option.

If you have a good terminal, then it's fine, but cmd is definitely not a good terminal

Riker

and because windows is shit, it forces its shitness onto vim

@DJMcMayhem what's that do?

DJMcMayhem

Well, not just windows. Using vim in xterm is also a little weird

Kritixi Lithos

18:21

@Riker Enables mouse interaction in all the modes afaik

DJMcMayhem

For example, even if you have :nnoremap <C-s> :w!<cr>, pressing <C-s> still hangs the process because xterm intercepts it before vim has a chance to process it

^^ yeah, ninja'd

Riker

wtf does nnoremap do

I keep seeing it

DJMcMayhem

It's like map but doesn't suck

Kritixi Lithos

@DJMcMayhem I face similar problems with xquartz, a terminal emulator for macs.

Q: What are the differences between the map, noremap, abbrev and noreabbrev commands?

These commands transform one set of keystrokes to another in some way, but I am somewhat fuzzy on which one is most appropriate for some situation. In addition, there are the ! variants of them as well. At the moment, my usage of them is pretty haphazard, so could I know what are the pitfalls ass...

If you're ever curious, I have all of my vim settings on github

Kritixi Lithos

18:24

I copied the inoremap kj <ESC> from your dotfiles

It's really useful

DJMcMayhem

I definitely agree. :)

I didn't come up with it though

This is one of my favorite settings: nnoremap <C-z> :call ToggleFullscreen()<cr>

function! ToggleFullscreen()
  if &lines < 26 || &columns < 80
    "TODO: Check for linux version
    simalt ~x
  else
    set lines=25 columns=80
  endif
  redraw

Kritixi Lithos

What's the & do?

DJMcMayhem

Uhhhhh....

I wrote that a long time ago >_<

Kritixi Lithos

lol

Riker

@DJMcMayhem what's the diff between normal mode, visual, select, and operator modes?

DJMcMayhem

18:29

Oh wait, I remember! It means "The value of this setting"

Riker

normal is commands like :quit right

just normal :commands

DJMcMayhem

Nope, normal is like hjkl dw jj Y p

Riker

oh

cool

DJMcMayhem

@Riker That's command mode

Riker

ah

what's visual and select then?

DJMcMayhem

18:30

Do you know what visual mode is?

Kritixi Lithos

Visual gets triggered when you select something using V or v or something similar

Riker

ah

DJMcMayhem

And select is almost the same thing except pointless. I just pretend select mode doesn't exist

Riker

hahahaha

> I am a little confused because I don't understand why this mode was created: all I can see is that it is less convenient than visual mode and doesn't provide more features.

4

DJMcMayhem

Hahaha, exactly

Riker

18:31

from here

Kritixi Lithos

Wait, select is different from visual o_O

Riker

> select mode doesn't exist

@KritixiLithos what's select? :P

DJMcMayhem

@Riker On the other hand, operator mode really useful/interesting. It's not generally something you'd learn about until you get to more advanced vim

Riker

oh cool

@Riker @DJMcMayhem pin pls

DJMcMayhem

But anyway, it means the mode that you enter when you call an operator and a motion is pending. So if you press d, vim sits and waits for a motion in o mode

Riker

18:34

oh, cool

@DJMcMayhem can I have RO status

I need to be able to selfstar abuse

DJMcMayhem

So try nnoremap w 2w and do dw

Kritixi Lithos

Aren't operator pending mode and motion similar?

DJMcMayhem

It still just deletes a word but if you do onoremap w 2w then dw will delete two words

@KritixiLithos Yeah, somewhat

Riker

cool!

DJMcMayhem has added Riker to the list of this room's owners.

Riker

18:35

also, I keep thinking of nnoremap as somebody saying "no remap pls" with a stutter

Kritixi Lithos

@Riker btw do you use airline.vim? It shows when you are in normal/insert/visual mode

Feeds

DJMcMayhem has removed Riker from the list of this room's owners.

DJMcMayhem

:P

Kritixi Lithos

haha

Riker

lol

@KritixiLithos nope

DJMcMayhem

18:36

I gtg

Cyall later

Riker

onoremap sounds like "o no remap pls nno remap no"

Kritixi Lithos

bye o/

Riker

@DJMcMayhem cya
