Default application for org-reveal

Default application for org-reveal

[Florian Lindner]

Hello,

the Org Attach dispatcher offers a key "f" to open the attachment directory not in Emacs.

(defun org-attach-reveal (&optional if-exists)
  "Show the attachment directory of the current task.
This will attempt to use an external program to show the directory."
  (interactive "P")
  (let ((attach-dir (org-attach-dir (not if-exists))))
    (and attach-dir (org-open-file attach-dir))))

On my two systems this is the same a F, it opens in dired. xdg-open . uses dolphin to open inode/directory. How does Emacs/org determine which
application to use? How can I influence it?

Thanks,
Florian

P.S. Why are file associations such a mess on Linux. Emacs? KDE and Thunderbird all use different applications to open the same file...

The documentation of `org-open-file' points to variable `org-file-apps'.
You can customize `org-file-apps'.

E.g. the entry

[INS] [DEL] Cons-cell:
            Choice: [Value Menu] Links to a directory
            Choice: [Value Menu] Command: firefox %s

stands for opening directories in firefox.


Ciao

Ok, thanks. I've set org-file-apps like that now

org-file-apps '((system . "xdg-open %s")
                            ("\\.pdf\\'" . system)
                            (directory . system)
                            (auto-mode . emacs)))

and it seems to work.

IMHO should mailcap be deprecated in favor of xdg-open.

Best,
Florian
