I have now finished porting at least backwards synchronization to the
new version of zathura. Patch attached.
Usage is as I described in the earlier mail:
-s: enables synctex support
-x <command>: sets the synctex editor (optional, see man synctex)
When synctex is enabled, ctrl-leftclick on the page will run "synctex
edit" with appropriate parameters, also forwarding the -x paratemer if
one was supplied to zathura. The synctex output goes to stdout/stderr of
zathura (but it's probably better to use the -x parameter to let synctex
automatically run the editor command instead of generating output).
When synctex is not enabled, ctrl-leftclick behaves just like normal
leftclick (same as without the patch).
I have tested this on Arch Linux with the default texlive installation
and the normal zathura packages installed (for the plugins).
I placed the new zathura binary in ~/bin and put the following lines in
.latexmkrc:
$pdf_previewer = "start ~/bin/zathura -s -x 'gvim --servername SYNCTEX
--remote +%{line} %{input}' %S";
$ps_previewer = "start ~/bin/zathura -s -x 'gvim --servername SYNCTEX
--remote +%{line} %{input}' %S";
