Is there a similar command to comment-kill that kills all comments in a given region and saves them to the kill ring?

  • You can narrow to region, put point at the beginning of the region, and call comment-kill with a large numeric prefix-arg. Pitingly that does not concatenate all kills. You can reach that with the following advice (caution: hacky!): (defun comment-kill-ad (fun &rest args) (kill-new "") (let ((last-command 'kill-region)) (apply fun args))) (advice-add 'comment-kill :around 'comment-kill-ad) – Tobias Sep 3 at 10:52
  • Presumably you don't just want to kill the region or copy it to the kill-ring. Instead, you want to kill only the comments in the region. Do you want them concatenated in the kill-ring, as one ring entry? Or do you want each comment to be a separate kill-ring entry. The question could be clearer. – Drew Sep 3 at 15:47

   (defun ar-kill-comment-atpt ()
      "Deletes comment at point if any. "
      (interactive "*")
      (ar-th-kill 'comment))

Requires stuff from https://github.com/andreas-roehler/thingatpt-utils-core providing the ar-th-kill basics.

Deletes all comments at point. Narrow to region before in order to restrict.
