Vim: Increment numbers in Vim

Hi,

I was wondering if it is possible to increment with VIM. For example
I'm trying to ping an IP range that needs to be contained in a file.
So I would like to create say 254 lines such as:

192.168.0.1
192.168.0.2
....
192.168.0.254

,without having the manually increment them yourself?

You can use <Ctrl-A> in command mode.

So if you have a line with

192.168.0.1

You can record a macro ("a") like:

qayyp$<Ctrl-A>q

And then:

252@a

to call the macro 252 times.

On GNU systems, you can also do:

:r! seq -f 192.168.1.\%g 254

Or if your shell is zsh:

:r! print -l 192.168.1.{1..254}

You can probably do some loops in vim language, but I don't do
that often enough for me to remember the syntax, so I'd need to
lookup the manual.

Hi Stéphane,

Great thanks, your macro idea was very useful, I must start trying to
use them more often.

With Vim's script language one can do

:for i in range(254) | execute 'normal o192.168.0.'.(i+1) | endfor

for example.

hi ,
it's a little a bit dirty but it works :
you need two marvellous features of Vim.

- you can record sequences of instructions with the 'q' command
(for exemple 'qa' will record the following sequence in the register 'a',
type 'q' again to close the sequence)
- C-a increment numbers !

so you type your first number
i 125.200.666.0
then you register the following sequence
qa yy p $ C-a q

Hit @a to execute your sequence and @@ to reexecute the last sequence.
50@a will do it 50 times.

I'm sure there is a clean way to put it into your vimrc or something
but I'm too lasy for searching .

I guess i've been too slow ^^.
I find Teemu's solution much better than mine.

To The List:

How may we nominate this as an example of brevity, simplicity, and
elegance?

could it be placed in the official Vim FAQ or one of the Vim
'Tips-n-Tricks' sites?

Hmm, let's make it even more elegant and simple:

:for i in range(1,254) | execute 'normal o192.168.0.'.i | endfor

The visincr plugin makes this pretty simple:
192.168.0.1
ma"ay'a (get a copy of the line into register a)
253"ap (make 254 total copies)

Now, use visual-mode (go to the rightmost 1, ctrl-v, G).
Using visincr: I

That'll make the visually-selected region an incremented list.

You can get visincr from:

http://mysite.verizon.net/astronaut/...x.html#VISINCR (cutting edge)
http://vim.sourceforge.net/scripts/s...?script_id=670 (stable)

Visincr also supports hexadecimal, octal, roman, day, and various date incrementing.

Anybody may add tips to the Vim tips wiki: http://vim.wikia.com/wiki/Main_Page
