I use C-x d *.org to list only files with .org extension. Is there a way to make this permanent for that directory? I have to do this every time I open that directory, it would be nice to have it permanently.

EDIT: add better solution in response to comment

The earlier given solutions were the easiest I could think of (and I hoped they would satisfy your requirements). However, I now found that the exact solution to your question actually is more or less as easy. This time, we just add the following :filter-args advice on dired-noselect:

(defun my-dired-org-filter-advice (args)
  (let ((dir (expand-file-name (file-name-as-directory (car args)))))
    (when (string= dir "/full-path-to-dir/") ; include final slash here
      (setf (car args) (concat dir "*.org")))

(advice-add 'dired-noselect :filter-args #'my-dired-org-filter-advice)

I'll keep the original answer below for the alternative solutions and for the 'modification' suggestions.


It is probably easiest to simply define a custom command for it. The exact form of the function then depends on your exact requirements. Here is a simplest example, in case you'd only use it for opening a single directory.

(defun my-open-org-dir ()
  (dired "/path-to-dir/*.org"))

Of course, the function can be made more general, where you could prompt for selecting a dir first.

After evaluating the above code, e.g. by adding it to your init file, and restart Emacs, you can call the function via M-x or bind the function to some key(-sequence).

If you prefer to 'modify' the original dired (C-x d) command, then you could add a :filter-return advice on the function dired-read-dir-and-switches to conditionally add (concat) *.org after the filename for certain (matching) directories. For example, you could use the following advice for it:

(defun my-dired-org-filter-advice (output)
  (let ((dir (car output)))
    (when (string= dir "/full-path-to-directory/") ;; include the final slash
      (setf (car output) (concat dir "*.org")))
    (print output)))

(advice-add 'dired-read-dir-and-switches :filter-return #'my-dired-org-filter-advice)

where, of course, you should fill in the correct full directory path. If you'd like to use it for multiple dirs, then replace string= by member and pass your list of directories.

  • Thanks, but I didn't exactly understand how I can use this. I will be pasting the code to my .emacs then how do activate it?

  • OP: You invoke it using M-x my-open-org-dir. Or bind that command to a key and use the key to invoke it.

  • @dalanicolai: You might want to show an example of defining the advice.

    I always prefer solutions where the code is generic and I can influence it from the outside, without having to modify it. But you are right: that's a different question.
