Hello!
I have some problem which I can't solve myself.
My goal is to run one specified function *each time* I enter
a directory in dired-mode. After some investigation I found
seemingly the right hook: dired-after-readin-hook. I defined the
test function foo:
(defun foo ()
(message "--> huhu"))
and add it to the above hook:
(add-hook 'dired-after-readin-hook 'foo)
Now when I enter first time a directory everything works fine -
I see in minibuffer '--> huhu'. The problem is when I leave the
directory (I do RET on '..', or press '^' - NOT kill buffer) and
enter this directory once again foo will be not called. I think
the reason is that in case of reenter of a directory - which
has already an existing buffer - dired only switch to this buffer
so the dired-after-readin-hook is not affected. But I can't find
no bufer hook that can solve my problem. Some analysis of lisp
code in dired.el (dired-find-file) and files.el (find-file)
brought no success.
Any ideas?
regards
Marc

Yes, I know, I talk to myself. However, this could also be interesting
to others. So I post my solution:
The advice idea was right! It works:
(defun foo ()
(message "--> hoho: current directory: %s" (dired-current-directory)))
(defadvice dired-find-file (after foo)
"Call foo each time on directory entry in dired."
(foo))
(ad-activate 'dired-find-file)

Hello Xah!
Please do not be offended but my answer is no. I completly disagree with
your Emacs and Lisp criticism and your "Emacs modernisation ideas" so I
don't want support your Emacs blogs. I don't want to be associated with
your point of view of Emacs.
regards
Marc
