Can relative number be changed so that current line is 1?

Question

I knew this site would teach me more about my beloved vim :-) In posting a question/answer on how to delete large blocks without having to count lines, one of the answers taught me something I didn't know, that being relative line numbers along the lines of:

  2 This is line 1
  1 This is line 2
3   This is line 3, the current line.
  1 This is line 4.
  2 Line 5.
  3 Line 6.

Now, if you wanted to delete lines 3, 4 and 5, you can simply add one to the relative line number (2) and use that to set the count, the command being 3dd.

However, adding one seems a bit obscure so I was wondering if you could configure the line numbers in relative mode to be more like this:

  2 This is line 1
  1 This is line 2
3 1 This is line 3, the current line.
  2 This is line 4.
  3 Line 5.
  4 Line 6.

That way you could simply transcribe the number into the command without having to think about it.

Answer 1

Don't do that. A numbering system that goes from -1 to +1 without a zero in between is just asking for trouble.

As an alternative habit, I suggest d2j — "delete this line and the next two lines". That works both ways: d2k deletes upward.

A long-winded ex command version of that would be :+2d.

Answer 2

Maybe: d<number><CR>
