Thanks Ramon,
Regarding your question, probably the bug is related to running a for
with all the buffers that are open. To get what you want you can try
something creating a minor mode for gpg files and adding a hook that
adds the buffer name of the gpg file that you open to a list of buffers
to kill:
#+BEGIN_SRC emacs-lisp
(define-minor-mode gpg-killing-mode
"A mode to kill gpg files"
:after-hook
(add-to-list 'gpg-buffers (buffer-name)))
(add-to-list 'auto-mode-alist '("\\.gpg$" . gpg-killing-mode))
(setq gpg-buffers nil)
(run-at-time t 120 '(lambda ()
(mapcar 'kill-buffer gpg-buffers)
(setq gpg-buffers nil)))
#+END_SRC
Instead killing all at the same time, I would probably kill each one
after a certain time, to avoid opening a file and have it right away
killed it was close to the end of the 2 min cycle:
#+BEGIN_SRC emacs-lisp
(define-minor-mode gpg-killing-mode
"A mode to kill gpg files"
:after-hook
(progn
(setq gpg-buffers (append gpg-buffers (list (buffer-name))))
(run-at-time 120 nil '(lambda ()
(kill-buffer (car gpg-buffers))
(setq gpg-buffers (cdr gpg-buffers))))))
(add-to-list 'auto-mode-alist '("\\.gpg$" . gpg-killing-mode))
(setq gpg-buffers nil)
#+END_SRC
Best,
Jorge.
