Keep cursor in same position on duplicated line in vim

I've added these shortcuts to duplicate a line based on the :t command, where :t. duplicates the current line onto the next line (keeps cursor on the second of the pair of lines), and :t-1 duplicates the current line onto the previous line (keeps cursor on the first of the pair of lines).

nmap <leader>D :t-1<cr>
nmap <leader>d :t.<cr>

In both cases the command moves the cursor position to the beginning of the line that has been created. How can I keep the cursor in the same position it was on (e.g. 20 characters in from the start of the line) on the new line?

Easiest solution is to use

:set nostartofline

Makes ex commands retain cursor column when possible, see h:nosol

Here is a solution:

nmap <leader>D mayyp`a
nmap <leader>d mayyP`a

It starts by placing a mark called a (ma) on the current cursor position, then copy the current line (yy) and paste it below (p). After that, it goes back to the original cursor position with `a. The second mapping uses P instead of p to paste the line above the current one.

This should do what you’re expecting.
