interactive
Here are some examples of interactive
:
(defun foo1 () ; foo1
takes no arguments,
(interactive) ; just moves forward two words.
(forward-word 2))
⇒ foo1
(defun foo2 (n) ; foo2
takes one argument,
(interactive "p") ; which is the numeric prefix.
(forward-word (* 2 n)))
⇒ foo2
(defun foo3 (n) ; foo3
takes one argument,
(interactive "nCount:") ; which is read with the Minibuffer.
(forward-word (* 2 n)))
⇒ foo3
(defun three-b (b1 b2 b3) "Select three existing buffers. Put them into three windows, selecting the last one."
(interactive "bBuffer1:\nbBuffer2:\nbBuffer3:") (delete-other-windows) (split-window (selected-window) 8) (switch-to-buffer b1) (other-window 1) (split-window (selected-window) 8) (switch-to-buffer b2) (other-window 1) (switch-to-buffer b3)) ⇒ three-b
(three-b "*scratch*" "declarations.texi" "*mail*") ⇒ nil
