Re: [AUCTeX] How to modify TeX-view-program-selection

[Greg Bognar]

Thanks for the suggestions.  Replacing "zathura" with "Zathura" helps, but also
removing the extra pair of parentheses around "((output-pdf "Zathura")):

(add-hook 'LaTeX-mode-hook 
'(lambda ()
  ;some other stuff
  (add-to-list 'TeX-view-program-selection '(output-pdf "Zathura"))
  ))

> There's no need to do this in LaTeX-mode-hook, it should be enough to have

(with-eval-after-load 'tex
  (add-to-list 'TeX-view-program-selection '((output-pdf "Zathura"))))

for reasons David mentioned.

Yes.  Thanks for pointing it out.

This leads to an error:

Wrong type argument: listp, "Zathura"

The value of TeX-view-program-selection:

(((output-dvi has-no-display-manager)
  "dvi2tty")
 ((output-dvi style-pstricks)
  "dvips and gv")
 (output-dvi "xdvi")
 (output-pdf . "Zathura")
 (output-html "xdg-open"))

I guess the problem is the extra period.

OK, but now each time I C-c C-c, I get a prompt:

View command: zathura file.pdf

Is it possible to get rid of the prompt?  Or should I just use C-c C-v instead?
