org-file-apps settings?

hi Everyone,
I have been through this a million times, but I never seem to remember, and
have a hard time finding the answer online or in my archives.

On a Linux system, how should I set org-file-apps to allow org to open odt
files in libreoffice, html files in Firefox, and pdf files in evince
(especially in export-and-open commands)?

I have tried a couple of htings; this is what C-h v org-file-apps currently
says:

Its value is ((remote . emacs) (system . mailcap) (t . mailcap))
Original value was
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

There's no /etc/mailcap on my mahcine (?), and .mailcap reads:

*/*; xdg-open "%s"


Running `xdg-open file.odt` from a terminal will open the file in
libreoffice, but exporting to odt and opening with C-c C-e o O opens the
file in emacs.  What should I try next? Thank you!

Hi Matt,

I'm not sure what the solution is for your system, but here's my
configuration:

org-file-apps is a variable defined in `org.el'.
Its value is ((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

I'm on Ubuntu Trusty on this system, and /etc/mailcap is a large file
containing many specific references to opendocument filetypes, etc.
When I export to ODT with "C-c C-e o O", the resulting file opens in
LibreOffice.

Hope this helps.

Hi Matt,

I can't stand evince so I've explicitly modified the default for pdf
files to open xpdf. It could also be used to make open-office files use the
application you want:

(add-hook 'org-mode-hook
           '(lambda ()
            (delete '("\\.pdf\\'" . default) org-file-apps)
	    (add-to-list 'org-file-apps '("\\.pdf\\'" . "xpdf %s"))))


Best Wishes.

Huh.  I am not really able to figure this out. I imagine that part of the
problem may be that org tries to use mailcap as a method, and I don't have
any mailcap files. So I attempted this, which does not work:

'((system . "/usr/bin/xdg-open %s")
  (auto-mode . emacs)
  ("\\.odt\\'" . system)
  ("\\.mm\\'" . default)
  ("\\.x?html?\\'" . default)
  ("\\.pdf\\'" . default) )

*Messages* reports that xdg-open has been run, but the file doesn't
actually run.  seting the odt entry to "/usr/bin/libreoffice %s" doesn't
seem to have any effect at all -- the file just opens in emacs. The only
thing that works for now is this bizarre workaround:
'((system . "/usr/bin/libreoffice %s")
   (auto-mode . emacs)
   ("odt" . system)
  ("\\.odt\\'" . "system")
  ("\\.mm\\'" . default)
  ("\\.x?html?\\'" . default)
  ("\\.pdf\\'" . default))
I don't undertand why this would work while the others don't. Of course,
this is a pretty lousy workaround since now everything opens in libreoffice
by default!

That is really weird, all right.  If it would help any, I could send you
my /etc/mailcap file.  Since Arch doesn't use one, maybe you could just
drop the one from my Ubuntu system in, and maybe it would work without
causing other problems...
