A similar report about using the *installed* evince for viewing DVI (instead of the not available xdvi): https://bugzilla.altlinux.org/show_bug.cgi?id=19557 . In 11.85-alt3 xdg-open is used instead xpdf. In this case emacs-mode-auctex should have a dependency on either xdg-utils or /usr/bin/xdg-open: $ rpmquery emacs-mode-auctex emacs-mode-auctex-11.85-alt3 $ rpmquery --requires emacs-mode-auctex | fgrep xdg $ We should better drop auctex-11.85-use-system-pdf-viewer.patch as it is: 1. contains a typo, leading to bug https://bugzilla.altlinux.org/show_bug.cgi?id=22278 2. patches in a wrong place, default system viewer should be changed by means of TeX-view-program-selection 3. xdg-open is not good replacement for evince, because it could not open a specified page of the document which is crucial when working in TeX-correlate-source (source specials) mode in auctex. В 4.0/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф. |
Description
Ivan Zakharyaschev 2009-03-18 23:30:36 MSKemacs-mode-auctex-11.84-alt1 emacs22-common-22.1-alt2 evince-gtk-2.20.1-alt0.M40.5 пакет xpdf не установлен I opened a LaTeX file, toggled the menu option "Command > TeXing options > PDF mode", C-c C-c (LaTeX), C-c C-c (View), and it wanted to run: xpdf -remote a -raise a.pdf although xpdf is not installed on this system (ALT Lite 4.0.3). But evince-gtk is. Expected: AUCTeX detects the installed program to view PDF, and uses it. (A trivial thing in modern times; something like that is expected from an OS nowadays, not manual setup of viewers for different types of files.) Comments on implementation of the feature: AFAIR, similar features for DVI (whether xdvi is available), dvips, dvilj etc. were implemented by making tetex-{xdvi,dvips,dvilj} put a scriptlet into /etc/emacs/site-start.d/ , which sets thevalues of the relevant Emacs variables. Perhaps, all the PDF viewers should put such a scriptlet to /etc/emacs/site-start.d/ , to inform Emacs how it can be used to view PDF. Another way would be to use the more common "database" of filetype-program associations (I don't know how it is called), so that Emacs just gives a command like "open a.pdf", and the system decides which program that is available to use.
