Only one org-open-at-point at a time?

Only one org-open-at-point at a time?

[Simon Guest]

Hi,

I'm using org-mode 5.10b on Debian GNU/Linux.

The first time I follow a hyperlink to a PDF file, using C-c C-o, it
works fine, and opens up the PDF file in the PDF reader specified in
/etc/mailcap, kpdf in my case.

If I leave that running, and try to follow another link to another PDF
file, I get told:
A command is running.  Kill it?  (yes or no)

It does not seem possible to view the second PDF file without killing
the first reader.

I would really like to be able to have both PDF files open at the same
time.  Is this easily possible?

(Of course, I doubt this is specific to PDF files, but this is the
case I am facing.)

cheers,
Simon

This small patch let you start a new process when you open an external
viewer from Org:

Bastien,

Thanks for this, just what I needed.

You could try using a shell link instead of a file link...
Something like: 

[[shell:kpdf%20foo.pdf][foo.pdf] 

If that doesn't work, you could try to design your own hyperlink type for pdf-
files.
See the org-manual (pdf version):
Appendix A.2 Adding hyperlink types 

Off-course it can also be that your kpdf viewer only allows on file opened at a 
time?

Hi Renzo,

Bastien already supplied a nice fix which works well - see his email.

cheers,
