Is it possible to get the start and end points in the buffer in which text is pasted?

Question

Like if you have a buffer containing hel! and paste in lo world after the third letter you get 4 and 11 respectively?

Emacs has many state variables, are there any that could help me in this case?

Answer 1

These are just point and mark right after the yank command. Just see the doc for yank or yank-pop. If you want to conserve these positions you could advice yank. Make sure that you save these values as markers or in buffer-local variables!

One more thing: If you want to see these values just once you can call M-: (mark) and M-: (point) right after the yank command.

Answer 2

Here's a quick snippet I came up with that does what you need on brief testing.

(defun my/get-yanked-text-boundaries ()
  "Yank and return the start and end boundaries of the yanked text in the buffer."
  (interactive)
  (let ((start (point))
        end)
    (call-interactively #'yank)
    (setq end (point))
    (message (format "Start: %0d End: %0d" start end))
    (list start end)))
