In VIM, Change the number that relative lines numbers start from

Question

I've turned on vim's relative line numbers, it starts from 0 but doing somthing like 10dd means I only get up to line 9, leaving the last one behind (becuase it's 10 including the current line). Yes, I know, It's only a super simple equation (10 + 1) but it's time taken up when I just want to check the number in the gutter and instantly get the number.

Is there a way to change the number the relative numbers start on? From 0 to 1? I've googled but I can't find anything and I did check out VIM's help page on the 'relativenumber' and 'number_relativenumber' sections but I couldn't see anything on it (or I probably missed it if it's there).

So is there any way to do this or is just not possible?

Well, vim is open source. If you clone it from:

git clone https://github.com/vim/vim.git

You can make the following changes to src/screen.c to do what you want:

diff --git a/src/screen.c b/src/screen.c
index 20a778a68..38d4368a9 100644
--- a/src/screen.c
+++ b/src/screen.c

But sorry, examining the source confirms there's no existing option available to do what you want.

Answer 2

You seem to be confusing ranges with counts.

d, y c, etc, take counts, not ranges, so will not work the way you expect.

Commands that take a range, such as :substitute, will work with relative line numbering, the way you seem to want. For example, :.,+10s/^/1 / will insert a 1 at the beginning of the current line, and the next 10 lines, inclusive.

To change the start number for relative line numbering would cause problems with using them to calculate ranges.

However, after additional testing, I've solved your real problem:

To delete from the current line, to relative line 10, the command you would use is d10j, 'd'elete, from the current line, for a count of '10', in the direction of 'j', or down.
