I don't need it that often either, but I had a sudden realization one
day, that pretty much the only times I DO need them, is when I'm
referring to code open in Vim while writing emails, problem reports,
and the like. So I put this gem in my .vimrc to automatically give me
absolute numbers only when I need them most often: when Vim doesn't
have focus.
if exists('+relativenumber')
" when Vim no longer has focus, relative line numbers are not
useful,
" although absolute numbers are
autocmd FocusLost * let s:FL_winnr = winnr() |
\ exec 'windo
\ if &ft !~ "txt" && &buftype=="" |
\ let w:nu_sav = &nu | let w:rnu_sav = &rnu | setl nu
|
\ endif' |
\ exec s:FL_winnr.'wincmd w' | unlet s:FL_winnr
autocmd FocusGained * let s:FL_winnr = winnr() |
\ exec 'windo if exists("w:nu_sav") |
\ let &l:nu = w:nu_sav |
\ unlet w:nu_sav |
\ endif |
\ if exists("w:rnu_sav") |
\ let &l:rnu = w:rnu_sav |
\ unlet w:rnu_sav |
\ endif' |
\ exec s:FL_winnr.'wincmd w' | unlet s:FL_winnr
endif
Incidentally, it was an earlier version of this which led to my
discovery that system() calls on Windows get FocusGained, but not
FocusLost. But that's even further off-topic than this discussion of
relative line numbering.
