`from' and `to' are variables but you used them like functions.  
Furthermore you write it as an interactive function but that function
should get called from `boxquote-kill-ring-save'; on the other hand
`buffer-name' is a function not a variable.

So it could be like that:

(defun my-title-function ()
  (save-restriction
    (widen)
    (format "%s [Lines: %s --- %s]" 
            (buffer-name)
            (line-number-at-pos (region-beginning))
            (line-number-at-pos (region-end)))))

Or you forget about the name and write:

(setq boxquote-kill-ring-save-title
        (lambda ()
          (save-restriction
            (widen)
            (format "%s [Lines: %s --- %s]" 
                    (buffer-name)
                    (line-number-at-pos (region-beginning))
                    (line-number-at-pos (region-end))))))

Thanks for pointing those out, I should read the lisp intro again!

That's much more efficient than mine.


Thank you!

title function for boxquote

[Sebastian Luque]

This should be simple, but I'm flailing badly here. I'm trying to put a title
to a boxquote that has been yanked from a region killed with
boxquote-kill-ring-save. Something that looks like:

file name [Lines: such -- such]

So I came up with this, but it doesn't work:

(defun my-title-function (from to)
   "Provide a phrase for boxquote-kill-ring-save-title."
   (interactive "r")
   (save-restriction
     (widen)
     (let ((first-line (count-lines (point-min) (from)))
 	  (last-line (count-lines (point-min) (to))))
       (concat buffer-name "[Lines: " first-line " -- " last-line "]"))))

(setq boxquote-kill-ring-save-title
      'my-title-function)

What's wrong with this picture? Thanks in advance.

Some debugging later...I got it:

,-----[ .emacs -- Lines: 277 - 288 ]
| (setq boxquote-kill-ring-save-title
|       (lambda ()
|  	(let ((from-line (count-lines (point-min) (mark)))
|  	      (to-line (count-lines (point-min) (point))))
|  	  (setq my-title
| 		(concat (buffer-name)
| 			" -- Lines: "
| 			(number-to-string from-line)
| 			" - "
| 			(number-to-string to-line)))
| 	  my-title)))
`-----

if anybody is interested.
