Hi,
Thanks for org, "the best tool in the world"! ;) (*)
I have a simple org file (Linux / Emacs 27.1 + Doom):
--------------
#+TITLE: Test pdf links
+ [[file:~/test.pdf][PDF 1]]
--------------
When I click on the link with mouse1, the document is opened in Calibre. When I use mouse3, the document is opened in Emacs. I get a similar behavior with org-attached PDF documents: using 'o' will open them in Calibre, 'O' in Emacs.
Such a behavior for mouse1/'o' raises 2 questions:
- My OS settings are configured so that PDFs are opened in Evince. I configured this with "xfce4-settings-manager > Default Applications" (which runs "xfce4-mime-settings" under the hood) and it can be verified with "xdg-open test.pdf" or by opening Thunar and clicking on "test.pdf".
So, where in the world does org-mode/Emacs finds that it should use Calibre instead of Evince?
- Now, I would like to circumvent this global OS behavior, so that Emacs itself would be used specifically to open PDF links in files I open in Emacs. When I was using Vanilla Emacs, I was advised to use pdf-tools, and given a config that was working. I translated that into my DoomEmacs config.org as follows:
(use-package! pdf-tools
:magic ("%PDF" . pdf-view-mode)
:config
(pdf-tools-install :no-query)
)
But apparently it does not override org's (default) behavior of opening PDF file with external tools.
Is there
Sorry for these (probably very) basic questions, but I could not find anything relevant on the web (or I haven't found the correct keywords...). I would be very grateful of any help!
Have a nice Week end

See https://orgmode.org/manual/Handling-Links.html#Handling-Links
(search org-open-at-point). The app selection is controlled by
org-file-apps customization.

No problem. This mailing list is open to all Org-related staff,
including basic questions. Do not hesitate to participate in the
discussion or ask anything.

I would name it desktop environment configuration since OS may have more
settings and it is your issue.
These settings likely alters ~/.config/mimeapps.list
https://specifications.freedesktop.org/mime-apps-spec/mime-apps-spec-1.0.html
"Association between MIME types and applications"
Unfortunately Emacs does not support this part of XDG specs, so there
are no ready to use functions to work with .desktop files and MIME
associations. You may add entries calling xdg-open for file types you
wish to the `org-file-apps' custom variable.

You may have mailcap configuration where Calibre has higher priority
than Evince, check /etc/mailcap
RFC 1524. A User Agent Configuration Mechanism For Multimedia Mail
Format Information
https://www.rfc-editor.org/rfc/rfc1524.html
Emacs has limited support of mailcap and it is used by Org mode.
Besides system configuration, Emacs has a set of predefined association.
Unfortunately the latter is broken in Emacs-27, see
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40247
#40247 - 27.0.90; mailcap-mime-data erased when parsing mime parts - GNU

The code of `org-open-file' is tricky. You may instrument this function
for debugging and step through it to realize what actually happens.
Maybe pdf-tools vs. doc-view mode choice is controlled by `auto-mode-alist'.
Concerning external viewer configuration, you may adapt for Evince the
following approach:

Likely the following entry in `org-file-apps' to override maicap by
xdg-open may allow to achieve what you expect:
(system . (lambda (file _link) (browse-url-xdg-open file))))
However links with page numbers (supported for "docview:" type out of
the box) will not work with such generic handler.
