xdg-open

xdg-open

[Katsumi Yamaoka]

Hi,

On Fedora 10, Gnus passes all image/* MIME parts to xdg-open,
that is the bash script, for displaying externally because of
the /etc/mailcap entry:

image/*; /usr/bin/xdg-open %s

It works if using it manually like: xdg-open image.png
In that case, the eog command is used for displaying the image
file.  However, in Gnus it simply ends up immediately with no
displaying.  So far I don't know why it won't do.  Instead, I
added this one to the ~/.gnus.el file to remove xdg-open from
`mailcap-mime-data':

(mailcap-parse-mailcaps)

(dolist (major mailcap-mime-data)
  (dolist (minor (cdr major))
    (when (equal (cdr (assoc 'viewer (cdr minor)))
		 "/usr/bin/xdg-open %s")
      (delq minor major))))

It's not a good idea, though.

Regards,

I had this problem under gnome (although not kde).  I believe it
dies because the child process, gnome-open, dies when the parent
process, xdg-open, finishes.  I did a hacky remedy of adding
'setsid' before gnome-open in the xdg-open script.  Since it works
okay from the command line though (and it does for me as well),
there may be something changeable within emacs/gnus that could fix
it.
