Generate a new buffer name

Generate a new buffer name

[mopi]

Hello friends

I use a lot of different buffers during a normal day. Often I don't
care what their names are, actually I feel that being forced to name
them interrupts me. I'm perfectly happy with the default naming that
other text editors use (Untitled-1, Untitled-2 etc).

I'm trying to replicate this behaviour in emacs. So far I have placed
this in my .emacs:

(global-set-key [(control n)]
		(lambda() (interactive)(switch-to-buffer(get-buffer-create
"Untitled1"))))

This gives me a new buffer named Untitled1. How can I make a variable
that increments so when I press C-n again I get a buffer named
Untitled2 and so on?

Maybe you could use `make-temp-name'?

Example:

 (make-temp-name "Untitled-")

  => "Untitled-3744WiN"

It is certainly possible to write a more advanced function that looks
for old "Untitled" buffers and increases the suffix with 1, but the
above might work for you.

Thanks. That works great!

(defvar next-untitled-buffer-number 0
   "document variable here")

(global-set-key [(control n)]
		(lambda()
		  (interactive)
		  (switch-to-buffer
		   (get-buffer-create
		    (format "Untitled-%d"
			    (setq next-untitled-buffer-number
				  (1+ next-untitled-buffer-number)))))))

(switch-to-buffer (generate-new-buffer "Untitled"))
