Tip: #19 - Display line numbers
Created: February 25, 2001 Complexity: basic Author: scrott Version: 5.7 Karma: 446/180 Imported from: Tip#19
I have started doing all my code reviews on a laptop because of the number command.
This will display line numbers along the left side of a window:
:set number
You can also define a mapping to toggle the option, for example:
:nmap <C-N><C-N> :set invnumber<CR>
By pressing Ctrl-N twice in normal mode, Vim toggles between showing and hiding line numbers.
If you have Vim version 7 or greater, you can change the width of the "gutter" column used for numbering:
:set numberwidth=3
You can use the number column for the text of wrapped lines:
:set cpoptions+=n
Finally, you can change the color used for the line numbers. For example:
:highlight LineNr term=bold cterm=NONE ctermfg=DarkGrey ctermbg=NONE gui=NONE guifg=DarkGrey guibg=NONE
