分享我处理行号的小script
用gn在rnu, nu, nonu间转换
" relative line number by default
set rnu
let s:number_setting = 1
function ToggleNumber()
if s:number_setting == 0
set rnu
let s:number_setting = 1
elseif s:number_setting == 1
set nu
let s:number_setting = 2
else
set nonu
set nornu
let s:number_setting = 0
endif
endfunction
" map gn to toggle rnu -> nu -> nonu
nmap gn :call ToggleNumber()<CR>
