Using comment characters for specific major modes

[martin-kemp]

I would not like to use the mini-buffer, but introduce the comment character 

according the the major mode being used on the buffer.



Is there a command that gets the current comment for the major mode used in the

working buffer ?



Would use the comment character twice  ";;"',  "cc", "!!", except for texinfo 
which

will use just "@c" as it is already composed of two characters.

OK and how do you propose to change the function?

Instead:

(defun my-fancy-thing ()
(interactive)
(let* ((initial (completing-read "Comment: " '("1 ;;" "2 !!") nil t))
(comment (substring initial 2))
(lena 10)
(string (make-string lena (string-to-char (substring initial 2)))))
(insert (concat comment " " string))))

then:

(defun my-fancy-thing ()
(interactive)
(let* ((initial (completing-read "Comment: " '("1 ;;" "2 !!") nil t))
(comment (substring initial 2))
(lena 10)
(string (make-string lena 59)))
(insert (concat comment " " string))))

;; ;;;;;;;;;;

Adopt the function to your needs.
