Hi Daniel,

sorry for my late reply, I have just caught up with the list again.

The patch works for me, but as in your patch for xournal, there is a
problem with non-ASCII characters. An "ü" arrives in emacs as "%C3%BC",
which are the two URL-encoded bytes which make up the character in UTF-8.

I don't know if this one is a bug in org-protocol, though, because AFAIK
unix filenames are just a bunch of bytes and evince might not be able to
find out what the encoding is supposed to be.

As I already indicated in the "Protocol for PDFs" thread, I realized
that docview: is just a syntax for specialized file: links.

Take a look at the following patch I posted to the mailing list two
weeks ago:
http://thread.gmane.org/gmane.emacs.orgmode/21474

This allows you to define customized file: links.
These are some entries from my org-file-apps variable:

	Extension: \.pdf\'
	Command: evince "%s"

	Extension: \.pdf::\([0-9]+\)\'
	Command: evince -p %1 "$s"
	
	Extension: \.xoj\'
	Command: /home/jan/.local/bin/xournal %s
	
	Extension: \.xoj::\([0-9]+\)\'
	Command: /home/jan/.local/bin/xournal -p %1 %s

This allows me to link to PDFs and Xournal files using normal file:
links, both with and without page numbers.

You could easily define a custom regexp which captures the page number
and the selection with groups, then uses them in a command as %1 and %2.

You can also use the groups in custom lisp forms, like this:
	Extension: \.pdf::\(.*\)::\(.*\)\'
	Lisp form: (progn
(message (concat "Page Number: " (match-string 1 link)))
(message (concat "Selection: " (match-string 2 link)))
(message (concat "File Name: " file)))

HTH, Jan
