Hi
I'm lagging behind the list... I recently saw the new duplicate-line
function and I feel I have an alternative, which also takes the region into
account:
;;
;; Duplicate region
;;
(defun duplicate-region-after (beg end add-cr)
"Insert a newline and duplicate after selection"
(let ((dupstr (buffer-substring-no-properties beg end)))
(goto-char end)
(when add-cr (insert "\n"))
(insert dupstr)))
(defun duplicate-line-or-region (arg)
"Duplicate the region or the line when nothing is selected"
(interactive "p")
(save-excursion
(let ((b (if mark-active (region-beginning)
(line-beginning-position)))
(e (if mark-active (region-end)
(line-end-position)))
_ign)
(dotimes (_ign arg)
(duplicate-region-after b e (not mark-active)))
)))
When and if I have CPU cycles I'd like to expand this to take a rectangular
region into account.
Best, /PA
