insert-file-name-into-minibuffer

[Alexander Klimov]

It is quite common to insert the name of the current file into the 
argument of shell-command or compile command (both use 
read-shell-command). I wonder what it the preferred way to do it?

I currently use the following to allow M-. or C-u M-. to be used to
insert the file name or its full path:

(defun insert-file-name-into-minibuffer (full-path)
  (interactive "P")
  (let ((path (buffer-file-name (window-buffer (minibuffer-selected-window)))))
    (insert (if full-path
                path
              (file-name-nondirectory path)))))
(define-key minibuffer-local-map (kbd "M-.") 'insert-file-name-into-minibuffer)
