pdf files with openwith only, and only this.

pdf files with openwith only, and only this.

[Joseph Vidal-Rosset]

Hi the list,

I do not want to use pdf-tools to view pdf in emacs, I want only to
use an external program (evince) to view pdf files. Unfortunately,
links to pdf do not work with openwith and my emacs open on a pdf. I
cannot delete pdft-tools that is a dependency of org-ref that I am
using. A solution for my setup would be welcome.

Best wishes,

Jo.

Try this:

(add-hook 'org-mode-hook
           '(lambda ()
            (delete '("\\.pdf\\'" . default) org-file-apps)
            (add-to-list 'org-file-apps '("\\.pdf\\'" . "evince %s"))))

Dear Colin (cc. John),

Many thanks ! Unfortunately, I have always the same result. Here is the message:

Viewing with pdf-view-mode
pdf-info-encrypted-p: pdf-info-epdfinfo-program is not executable

is org-ref the culprit? I cc. to John Kitchin.

Best wishes,

Jo.

That is odd. I slightly modified my code for your situation of using
evince. I actually use xpdf and

 (add-hook 'org-mode-hook
           '(lambda ()
            (delete '("\\.pdf\\'" . default) org-file-apps)
            (add-to-list 'org-file-apps '("\\.pdf\\'" . "xpdf %s"))))

works for me. I assumed just changing xpdf to evince would be
sufficient.

Something more subtle may be happening.

I don't think org-ref is responsible, except that it installs pdf-tools.
When I click on a link like
[[./2019-07-04.pdf]] it opens in acrobat for me.

I don't have anything fancy
org-file-apps is a variable defined in `org.el'.
Its value is
((auto-mode . emacs) ("\\.mm\\'" . default) ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

which I guess means on osx that it gets opened with "open".

It looks like you can do this

#+BEGIN_SRC emacs-lisp
(setf (cdr (assoc "\\.pdf\\'" org-file-apps)) "evince %s")
#+END_SRC

to make it open in evince.

Yes, that works for me too.

Dear John,

Thanks for  your reply. In  fact my problem is  only at the  moment with
pdf links  in gnus, not  in usual org files.  (Maybe I should  switch for
mu4e, but I  hesitate and I would be  happy to find a tutorial  to do it
with gmail.)

I    have    solved    temporarily    the   problem    with    eimp    :
https://emacs.stackexchange.com/questions/2433/shrink-zoom-scale-images-in-image-mode

and the pdf in emacs are now more easily readable for me. 

Best wishes, and again, to Colin and to you, many thanks.

My guess is the problem is with doc-view mode and possibly guns setup. I
had a similar issue some years back, but cannot quite remember how I
resolved it. My problem was that I had elisp I wrote which would use
external viewers for various document types (e.g. word doc, pdf, etc),
but when I tried to use it, Emacs would jump in the middle and use
docView mode to display it inside emacs itself.

From memroy, the basic fix was to turn off doc-view-mode (posibly check
out the customization group). With respect to gnus (and other mailers),
most of them include some sort of variable which sets which mime types
can be displayed internally. If you don't want to completely disable
doc-view-mode, you should be able to change this setting to say that
PDFs are tro be displayed externally using whatever program is
associated with that mime type.

Dear Tim, John and Colin,

You are right Tim, for Gnus, the solution to my problem was here :

https://www.emacswiki.org/emacs/MimeTypesWithGnus

and here:

https://lists.gnu.org/archive/html/info-gnus-english/2016-04/msg00002.html

But I just realize that Gnus gives the choice to open "internally", or
"externally"... :S

Best wishes and many thanks for your very kind help,

Jo.
