I am trying to link to a specific page in a pdf file using org-docview.
For example, I have a org file with the following header
** [[docview:~/Desktop/2013_test.pdf::3][Digital modulation notes]]
However, when I double click on the link I get the following error
Invalid image file name `nil'
Does anybody know to fix this problem ?
Thanks
M

Seems to work here[fn:1]. One thing that seems slightly broken is that
if the file is huge and docview takes a while to convert it, then the
goto-page part does not seem to be effective:
,----
| (defun org-docview-open (link)
| (when (string-match "\\(.*\\)::\\([0-9]+\\)$" link)
| (let* ((path (match-string 1 link))
| (page (string-to-number (match-string 2 link))))
| (org-open-file path 1) ;; let org-mode open the file (in-emacs = 1)
| ;; to ensure org-link-frame-setup is respected
| (doc-view-goto-page page)
| )))
`----
It stays on p.1 in that case. It works OK for small files.
Can you turn on debug-on-error and post the backtrace?

[fn:1] Org-mode version 8.0.2 (release_8.0.2-72-gccfe83 @ /home/nick/elisp/org-mode/lisp/)

Hi Nick,
I tried this, but no luck. I am using emacs 24.3.1 on the mac. Doc-view is included included in this version of emacs, will this conflict with org-docview ?
cheers

Not sure what "this" is: What exactly did you try?
In any case, org-docview is the implementation of links on top of doc-view, so
there is no conflict (iow, org-docview *requires* doc-view).

You seem to have a buggy version of doc-view.el: doc-view-current-files is
not used by doc-view-goto-page in the version that I have, which is the
version bundled with
GNU Emacs 24.3.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10)
of 2013-04-09
In my version of doc-view-goto-page, there is a comment that says:
,----
| ;; Update the buffer
| ;; We used to find the file name from doc-view-current-files but
| ;; that's not right if the pages are not generated sequentially
| ;; or if the page isn't in doc-view-current-files yet.
`----
which leads me to believe that you will need to upgrade your version
of doc-view (or perhaps your emacs).

Hi Nick,
I just updated to a newer version of emacs, which now solved the problem.
The only remaining issue is that I have to manually switch to doc-view-mode to view the pdf. Is there away to do this automatically ?
Thanks

AFAIK, this happens automagically (but I don't know what magic is used:
it does not seem to be hooks however, which was my first guess). Do you
get the raw PDF in Fundamental mode? Does C-c C-c do anything?

Check your auto-mode-alist: for PDF, the associated function should be
doc-view-mode-maybe.

Your suggestion worked. Adding doc-view-mode-maybe to the auto-mode-alist rendered my pdf automatically.
I really appreciate your help.
