pdf viewer

[Kamil Jońca]

For some time emacs view pdf files with its internal viewer.
But I want to keep old behavior - open them with xpdf/evince
How can I do it? I google some but without success.

You can use mailcap-user-mime-data variable to override the (generated)
defaults in mailcap-mime-data:

    (setq mailcap-user-mime-data
          '(((type . "application/pdf")
             (viewer . "evince %s"))))

Is this from org-mode? If yes, this snippet works for me:

     (setq org-file-apps
          (cons
           '("\\.pdf\\(?:::\\([0-9]*\\)\\)\\'" . "xpdf %s %1")
           (assoc-delete-all "\\.pdf\\'" org-file-apps)))

Otherwise you might want to have a look at doc-view-mode: I think
this is the one responsible for displaying the pdfs whithin Emacs.

My emacs uses its internal viewer doc view, and yet I see this in my
predefined (I didn’t touch it myself) mailcap-user-mime-data:

#+BEGIN_SRC elisp
  ("pdf"
   (viewer . "okular '%s'")
   (type . "application/pdf")
   (test "test" "\"$DISPLAY\"" "!=" "\"\"")
   ("nametemplate" . "%s.pdf"))
#+END_SRC

Also mine is huge, wouldn’t what you proposed erase it all? Wouldn’t
`add-to-list' be more appropriated?

#+BEGIN_SRC elisp
  (add-to-list 'mailcap-user-mime-data
               '((type . "application/pdf")
                 (viewer . "evince %s")))
#+END_SRC

No, mainly from mails (gnus).

Are you sure you speak about mailcap-user-mime-data, not
mailcap-mime-data?

I have huge mailcap-mime-data, but mailcap-user-mime-data was
empty/undefined.

You are indeed right, I confused both: as it was undefined C-h v didn’t
worked, and I didn’t realize auto-completion did show me another
variable. Sorry.

You can also use a hook. This works for me:

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

While I understand you wanting not to use doc-view-mode, did you try
pdf-tools?  It replaced xpdf/evince for me almost completely.

The point is, pdf-tools works within Emacs. :)

Part of the trouble is that mailcap.el defines a sort function that
favours symbols over strings.  As a result, no matter what viewer
command you have, 'doc-view-mode will win out.

I have used a temporary fix which is to have

(require 'mailcap)
(setq mailcap-mime-data nil)
(mailcap-parse-mailcaps nil t)

in .emacs.  This is a crude fix, but it works for the time being.

I started a thread about this a few days ago in comp.emacs and there
have been some other ideas along the line of code to pickout the
'doc-view-mode a-list entries.

If this is true, we should have a bug report about this problem.

There had been "bug#23184: 25.0.92; User-friendly way to override
doc-view-mode as MIME viewer", but it seems you say that didn't solve
the problem for you.

I also found commit 7e47d44da4b54c518c5e09b4f3d58dafdd43033d "Prefer
settings from ~/.mailcap over system and Emacs settings" from Lars from
six months ago, dunno if it is relevant.
