Most of time I do not use `interactive' for supply arguments to
function.
Thus instead of following:
(defun my-fun-1 (&optional name)
(interactive "MName: ")
(message "Hello %s" name))
I am using following:
(defun my-fun-2 (&optional name)
(interactive)
(let ((name (or name (read-from-minibuffer "Name: "))))
(message "Hello %s" name)))
as that gives me little more freedom:
- if I call (my-fun-1) ⇒ "Hello nil" that result is not what I
really want. It makes it difficult to get the wanted result. To
get the wanted result I need to use:
(call-interactively 'my-fun-1) ⇒ "Hello Bob"
- but if I call (my-fun-2) and NAME is not supplied, I will be
asked for name: (my-fun-2) ⇒ "Hello Bob" and will not get "NIL"
as result. In this case I need not complicate the call and use
`call-interactively`.
Additionall, complex `interactive` clauses I find often too
difficult to comprehend than reading the body of the function.
Fo this reason I recommend using this second approach with (or
ARGUMENT (GET-ARGUMENT)) rather then using `interactive` with
purpose to supply arguments.
