How do I increase the spacing of the line number m

Question

I have a problem with my colorscheme in vim:

_{(source: tinygrab.com)}

The line numbers are too close to the code. How I can increase the width of the line numbers' right margin?

Answer 1

Looking at the code, it turns to be impossible (without patching the vim, obviously): vim always formats the line numbers to take up the whole available width, leaving just a single space afterwards (the "%*ld " format specifier in the code makes sure of that).

Answer 2

You can add the following line in your "~/.vimrc":

set nuw=6

Where "6" specfies the width of the column in terms of number of characters. Replace with a smaller or large number as needed. Only works with more recent (>=7?) versions of Vim, I think.

Answer 3

This bothered me, too; I hate having text crammed up against a block of solid color. It makes me claustrophobic.

Here's what I did as a workaround (in MacVim, but I expect the same technique will work elsewhere):

In your preferred colorscheme, set the background color of the line-number column to be the same as the background color for normal text, and the line-number foreground color to something low-contrast and unobtrusive (so it doesn't look like it's part of your normal text). I use white-on-black for normal text, and dark-grey-on-black for the line numbers:

hi LineNr  guifg=#505050   guibg=Black
hi Normal  guifg=White     guibg=Black

Admittedly, this doesn't fix the problem so much as hide it, but it's worked well for me.
