Dear all, I dare to ask this slightly off-topic question, because of the discussion about pdf-tools a day ago.
I installed pdf-tools (https://github.com/politza/pdf-tools). It is a _lot_ faster than doc-view. Many thanks to Matt Price (http://matt.hackinghistory.ca/2015/11/11/note-taking-with-pdf-tools/) I got it working with orgmode. But I'd like to use it to display my PDFs I produce with LaTeX (Emacs, AUCTeX) as well. The trouble is the automagic reloading of the PDF every time it get's changed on disk. Okular does this, but pdf-tools need some kind of invitation?! >From here https://github.com/politza/pdf-tools/issues/128 is this setup for .emacs: ============= 8< ============== (pdf-tools-install) (load "pdf-tools") (setq TeX-view-program-selection '((output-dvi "Okular") (output-pdf "PDF Tools") ;; )) (require 'subr-x) (defun th/pdf-view-revert-buffer-maybe (file) (when-let ((buf (find-buffer-visiting file))) (with-current-buffer buf (when (derived-mode-p 'pdf-view-mode) (pdf-view-revert-buffer nil t))))) (add-hook 'TeX-after-TeX-LaTeX-command-finished-hook #'th/pdf-view-revert-buffer-maybe) ================ >8 ============ If I compile a *.tex file again, I get the error "error in process sentinel: Symbol's function definition is void: when-let" ...and the PDF won't get updated. Can anybody help me to get a working setup? Really, this libpoppler behind pdf-tools is such a lot faster, it reminds me on xpdf. I'm on Linux, Emacs 24.5.1 and AUCTeX 11.89. Thanks! Alexander
