kill the associated buffer when close the emacs-client frame by pressing Alt+F4

Question

I get used to emacsclient for the speedy response like vim, by putting emacs into sever mode with command "emacs --daemon". But I found it quite annoying that lots of buffers kept alive when I viewed some files and then closed them by pressing Alt+F4. I have to kill the buffer explicitly before closing the frame.

I want to know, if there is a way to make emacsclient behave more like a lightweight GUI editor(e.g. vim) in this point?

Answer 1

I think you're asking for trouble, but you you could try this:

(add-hook 'delete-frame-functions
          (lambda (frame)
            (let* ((window (frame-selected-window frame))
                   (buffer (and window (window-buffer window))))
              (when (and buffer (buffer-file-name buffer))
                (kill-buffer buffer)))))

Answer 2

I suggest that you use the command quit-window which does precisely what you want (with the prefix argument); it is already the binding for q in special-mode (i.e., not self-insert) buffers. You can bind it to, say, C-f4, and it will kill the buffer and the frame when you type C-u C-f4.
