A short note on how-to set a pdf-viewer for LaTeX-generated documents in Emacs.
My favourite editor Emacs provides a great support for LaTeX document preparation system. There are several modes that extend the default latex-mode. My favourite ones are: AUCTex (with Preview-latex) and CDLaTeX.
By-default LaTeX outputs DVI files and uses xdvi viewer with "View" command. However it's possible to configure LaTeX to outpud pdf files. In Emacs, you have to execute (M-x tex-pdf-mode) command to set the LaTeX's output to pdf. If you'd like to have a pdf output for all LaTeX documents, add
(setq TeX-PDF-mode t)
to your .emacs.
Now, let's add a pdf-viwer to be executed on "View" command (C-c C-v). I use GNOME's default Evince document viewer for pdf files. So, the code that should be added to .emacs is:
1 2 3 4 5
(defun pdfevince () (add-to-list 'TeX-output-view-style '("^pdf$" "." "evince %o %(outpage)"))) (add-hook 'LaTeX-mode-hook 'pdfevince t) ; AUCTeX LaTeX mode
