Copy text at line N at point

Question

How can I make a function that copies text from line number N at point? I will be at some specific line and point position and want to copy the text from a different line N.

(defun foo (n)
  "Copy line N to the kill-ring.
N is the numeric prefix arg"
  (interactive "p")
  (save-excursion
    (goto-char (point-min))
    (forward-line (1- n))
    (kill-ring-save (line-beginning-position) (line-end-position))))

How would I use it? – Dilna Jan 28 '23 at 03:18
I would like to have a variation where I can pass the line number N from the mode-line. – Dilna Jan 28 '23 at 03:28
You say C-u N M-x foo RET C-y where N is the desired line number. – NickD Jan 28 '23 at 03:34
"... from the modeline" - you mean from the minibuffer? – NickD Jan 28 '23 at 03:35
From minibuffer that you say. – Dilna Jan 28 '23 at 04:07
Then change the interactive spec to prompt for a number. That's a trivial change. I answered the question as posed. If you want some specific behavior, you should specify it in your original question - don't "evolve" questions. – Drew Jan 28 '23 at 17:42
