The function to show current file's full path in mini buffer

I need to get the full path of the file that I'm editing with emacs.

  • Is there a function for that?
  • If not, what would be the elisp function for getting that?
  • How can I copy the result (path name) to a clipboard so that I can reuse it?

I'm using Mac OS X and Aqumacs. 

(setq filepath (get-fullpath-current-file)) ???
(copy-to-clipboard 'filepath) ???

ADDED

(defun show-file-name ()
  "Show the full path file name in the minibuffer."
  (interactive)
  (message (buffer-file-name))
  (kill-new (file-truename buffer-file-name))
)
(global-set-key "\C-cz" 'show-file-name)

Combining the two answers that I got, I could get what I want. Thanks for the answers. And some more questions.

  • What's for (file-truename)?
  • Can I copy the path name to System(OS)'s clipboard, not the kill ring so that I can use the info with the other apps?

You can if you shell out to something like xclip (Linux), pbcopy (Mac), putclip (Cygwin).

I personally use wrapper scripts c and p for copy and paste respectively, the first reading from standard input, the latter writing to standard output. That way, this works on all my development platforms:

(shell-command (format "echo '%s' | c" buffer-file-name))

I find this more reliable and configurable than using the Emacs clipboard support. For example, my c command copies the input to all 3 clipboards on Linux (primary, secondary, clipboard), so I can paste with either Ctrl-V or middle click.

To do what the title says (show the current file path in the minibuffer) you can do this:

M-x buffer-file-name

To permanently show it in the mode-line, you can use this:

(setq-default mode-line-buffer-identification
              (list 'buffer-file-name
                    (propertized-buffer-identification "%12f")
                    (propertized-buffer-identification "%12b")))

Or this (color + abbrev) :

(setq-default mode-line-buffer-identification
              '((:eval
                 (list (propertize (abbreviate-file-name
                                    (expand-file-name buffer-file-name))
                                   'face 'font-lock-string-face)))))
