orgmode & pdf-tools

orgmode & pdf-tools

[AW]

Hi!

Linux, Orgmode 8.3.4, org-file with many links. Recently I discovered pdf-
tools, which can display PDFs inside Emacs, just like docview, but much 
faster. 

I'd like to 

1. open via a given link from inside the org-file using C-c C-o 

2. the PDF with pdf-tools 

3. on a given page. 

Result: PDF is being opened, but always on p. 1 instead of e.g. page 5!

.emacs:

(eval-after-load 'org '(require 'org-pdfview))
(delete '("\\.pdf\\'" . default) org-file-apps)
(add-to-list 'org-file-apps '("\\.pdf\\'" . org-pdfview-open))
(add-to-list 'org-file-apps '("\\.pdf::\\([[:digit:]]+\\)\\'" . org-pdfview-
open))

link in org-file:

[[./localfile.pdf::5]]


Same setup works under windows with other viewer. So probably there is an 
error in those lines above. Any hints? -- Thank you!

Regards,

Alexander

. . .   A N D  openSUSE!

Links of the form [[./foo.pdf::3]] still are being opened on p. 1 instead of 
page 3. For description of my issue, see my report from April 3rd below. 

Me, being a user, I can't solve this. I'm on openSuse, current Tumbleweed. I 
managed to install PDF-Tools properly, after I found out that you need to 
install Cask before loading down the package via Melpa.

Those lines below from my .emacs work in other installations, as the 
maintainer of org-pdfview.el wrote. 
(https://github.com/markus1189/org-pdfview/issues/10)

I build a short .emacs, only the necessary links and packages, to orgmode and 
PDF-Tools. No success. 

IS SOMEBODY READING THIS WHO USES openSUSE ?

I tried but failed to find an error with edebug, but this seems way beyond my 
skills.

   After edebugging org-open-file I found a possible solution. The
documentation string for org-file-apps should be modified for the sexp
case to use the link variable instead of file.

#+BEGIN_SRC elisp
(add-to-list 'org-file-apps '("\\.pdf\\'" . (org-pdfview-open link)))
(add-to-list 'org-file-apps '("\\.pdf::\\(\\d+\\)\\'" . (org-pdfview-open link)))
#+END_SRC

I'm not sure about what the initial problem is, but there is no more
"sexp" case in `org-file-apps' in development version. You can use
a function instead.

@ Pablo, thank you, that solved it! Great!

@ all:
My initial setup was:

(eval-after-load 'org '(require 'org-pdfview))
 (delete '("\\.pdf\\'" . default) org-file-apps)
 (add-to-list 'org-file-apps '("\\.pdf\\'" . org-pdfview-open))
(add-to-list 'org-file-apps '("\\.pdf::\\([[:digit:]]+\\)\\'" . org-pdfview-
open))

Now and working:

 (eval-after-load 'org '(require 'org-pdfview))
 (delete '("\\.pdf\\'" . default) org-file-apps)

(add-to-list 'org-file-apps '("\\.pdf\\'" . (org-pdfview-open link)))
(add-to-list 'org-file-apps '("\\.pdf::\\(\\d+\\)\\'" . (org-pdfview-open 
link)))

So the way to include org-pdfview-open did not work with openSuse and Emacs 
24.5

If somebody _please_ could swap the "sexp" in org-file-apps with whatever 
function, as Nicolas mentioned? It really is helpful to open a lengthy PDF at 
the right page...

And sorry for answering so late, I missed the email.

Alexander
