aw. why on earth was this question migrated to SU? It is a programming question related to a prorgramming tool. It doesn't get more SO than that. The programmers that focus on SO (like me) would now not be able to find this answer because 5 people don't know what vim is. Go figure.

if &nu == 1
   set rnu
elseif &rnu == 1
   set nornu
else
   set nu
endif

@JuanPablo: mmm. I like my version better :) – sehe Sep 24 '11 at 20:19
@sehe: I'd say the same about my version. :-) – ib. Sep 25 '11 at 3:51

Because I love a logic puzzle, and really love it when a vim command fits on a single line for succinct repeats (@: is a personal favourite):

:exec &nu==&rnu? "se nu!" : "se rnu!"

This will maintain the same cycle. I think it is mainly because let &nu=1 will implicitly set norelativenumber - for reasons probably found in the documentation :)

+1 as I can place it in my .vimrc file as one line of nmap <F3> :exec &nu==&rnu? "se nu!" : "se rnu!"<CR> to toggle through three options using F3. – nye17 Sep 24 '11 at 23:38

you could make that nnoremap <silent> <F3>... to reduce visual distraction and interfering with other mappings. – sehe Sep 24 '11 at 23:56
I came up with almost the same (but shorter :-) line when read the question: exe'se'&nu+&rnu?'rnu!':'nu'. – ib. Sep 25 '11 at 2:51
By the way, to assure yourself of the connection between number and relativenumber options, see :helpg When setting this option. – ib. Sep 25 '11 at 2:54
@ib: thanks for sharing. I really love your vim code golfs - there are gems in there that really speed up my everyday work; In this case, however, I have specificly selected my version (a net 3 characters longer - besides whtiespace cramp) because it is legible. In my view, there isn't any gain from condensing it further: it does get harder to type and a lot harder to remember even if you ever had to type it from memory. This is going to be in a mapping. So Benoit's version is fine, except for it not fitting nicely on a single line – sehe Sep 25 '11 at 12:08
