Hi,
Below are my code:
------------------------------> Code start <------------------------------
(defun duplicate-line-above (&optional reverse)
"Duplicate current line above."
(interactive)
(let ((origianl-column (current-column))
line-content)
(setq line-content (buffer-substring (line-beginning-position) (line-end-position)))
(beginning-of-line)
(and reverse (forward-line +1))
(newline +1)
(forward-line -1)
(insert line-content)
(goto-column origianl-column)))
(defun duplicate-line-below ()
"Duplicate current line below"
(interactive)
(duplicate-line-above t))
(defun duplicate-line-above-comment (&optional reverse)
"Duplicate current line above, and comment current line."
(interactive)
(if reverse
(duplicate-line-below)
(duplicate-line-above))
(save-excursion
(if reverse
(forward-line -1)
(forward-line +1))
(comment-or-uncomment-region+)))
(defun duplicate-line-below-comment ()
"Duplicate current line below, and comment current line."
(interactive)
(duplicate-line-above-comment t))
------------------------------> Code end <------------------------------
You can find those code at http://www.emacswiki.org/cgi-bin/emacs/lazycat-toolkit.el
Below are my keybing for those command:
------------------------------> keybinding start <------------------------------
("C-S-o" . duplicate-line-above)
("C-S-l" . duplicate-line-below)
("C-S-s-o" . duplicate-line-above-comment)
("C-S-s-l" . duplicate-line-below-comment)
------------------------------> keybinding end <------------------------------
Enjoy!
