File path to clipboard in Emacs

Question

What is the most simple way to send current full file name with file path to clipboard?

What I am using now is messages buffer: I copy file name that appears there after

Answer 1

In Emacs Prelude I use:

(defun prelude-copy-file-name-to-clipboard ()
  "Copy the current buffer file name to the clipboard."
  (interactive)
  (let ((filename (if (equal major-mode 'dired-mode)
                      default-directory
                    (buffer-file-name))))
    (when filename
      (kill-new filename)
      (message "Copied buffer file name '%s' to the clipboard." filename))))
