Here's a small function I borrowed from this question on stack-overflow. It returns the full path of the file I currently edit in the buffer:
(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)
You'll note that this function is bind to
C-c z. So when typing it,
you should see the path showing in the minibuffer. As a bonus, it stores
the path in the kill ring, so
CMD-v works as well on my mac)
will paste the value.
