[zathura] synctex, open a new file on a specified line

[Maxim Gonchar]

Hi,

after some playing and searching the internet I was able to use zathura
synctex support, by opening a file:
zathura -s -x 'gvim --servername SYNCTEX --remote +\%{line} \%{input}'
Introduction_en.pdf
and switching to the specified line:
zathura --synctex-forward 100:1:<fullpath>/Introduction_en.tex
Introduction_en.pdf

If I try to combine these two commands I get an error saying that the
opened instance for Introduction_en.pdf is not found.
I wonder why this distinction is made? Is there a way to open zathura and
sync if file is not opened, or simply sync if the opened instance exists?

Here is the vim code to sync or run zathura, which is ugly, because
instead of one function I need three:

function! StartZathura( pdfname )
let cmd = "silent !zathura -s -x "
let backcmd = "'gvim --servername ".v:servername." --remote
+\\%{line}
\\%{input}' "
let execstr = cmd.backcmd.a:pdfname.'&'
exec execstr
endf

function! SyncZathura( pdfname, status )
let cmd = "silent !zathura --synctex-forward "
let path = line(".").":".col(".").":".expand("%:p")." "
let execstr = cmd.path.a:pdfname
if !a:status
let execstr.=' &'
endif
exec execstr
return v:shell_error
endf

function! StartOrSyncZathura( pdfname )
if !SyncZathura( a:pdfname, 1 )
return
endif
call StartZathura( a:pdfname )
sleep 300m
call SyncZathura( a:pdfname, 0 )
endf

regards,
Maxim

It's just that nobody had any use for anything like that yet so it's just not
there - doing anything after a document has been opened was always a pain to
time right. But if there's interest in something like that, we can fix that.

That would be great! Thanks.

Something like this is very useful when I open up a PDF viewer from my
editor (Vim of course). I'd like to have one mapping that opens a PDF
(if it's not already open) and then syncs to the current location.

However, this functionality can be trivially added with a little
scripting. See here:

PS: Thanks a ton for implementing forward searches. I finally was able
to abandon Xdvi, and now do everything with PDF files.
