Vim+Zathura+Synctex

• In a script called 'vimura':

#!/bin/sh
echo $1
zathura -s -x "gvim --servername $1 -c \"let g:syncpdf='$1'\" --remote +%{line} %{input}" $*

For zathura >= 0.3.2 remove -s.

• In your vimrc:

function! Synctex()
        " remove 'silent' for debugging
        execute "silent !zathura --synctex-forward " . line('.') . ":" . col('.') . ":" . bufname('%') . " " . g:syncpdf
endfunction
map <C-enter> :call Synctex()<cr>

• Build your latex doc with synctex enabled

pdflatex -synctex=1 ...

• Open PDF with vimura script.

• CTRL+Click in Zathura jumps to source in vim.

• CTRL+Enter in vim jumps to corresponding position in PDF.

The answer by @perelo led me to the following latex.vim snippet for my nvim configuration:

function! OpenZathura()
    let position = line('.') . ":" . col('.') . ":" . expand('%:p') . " "
    call jobstart("zathura -x 'nvr --remote +%{line} %{input}' --synctex-forward " . position . " " . substitute(expand('%:p'),"tex$","pdf", ""))
endfunction
map <leader><Enter> :call OpenZathura()<cr>

I would love to hook in any motion to automatically call the function (which by some miracle doesn't reopen a new process, unless it's not open yet), but only if I already opened Zathura manually. Any ideas on how to do this? Having one function to only open Zathura (which I thought I had), and one to re-sync the position sounds like the ideal solution.

As a note, I had misconfigured texlab (getting cmd ["texlab"] is not executable errors), causing me to have to press enter after pressing Ctrl+Click in Zathura. I disabled the LSP server for texlab, and synctex works without any problem. I still need to clean up the LSP. Regardless, is there some way of "ignoring" this error message, or appending a <cr> keypress through nvr?

You can have it trigger on CursorMoveI events on *.tex file patterns.

autocmd CursorMoveI *.tex call OpenZathura()

With this whenever you enter insert and move around your cursor, zathura would do the same.
But this also implies that you have to compile (if it's not compiled ) before entering insert mode.

I have another command to compile any *.tex file on BufReadPost and BufWritePost so i don't have to always remember about compiling it first.
In my case it's not necessary to have zathura opened already. If the pdf file already exist , it (that function ) would open up without any problem

Nice! Didn't know about CursorMoveI, I'll add this myself when I get to it :)

@mazunki
This is my tex autocmd group

  augroup latex
    autocmd! CursorMovedI *.tex call OpenZathura()
    autocmd! BufWritePost,BufReadPre *.tex silent !compiler %
  augroup end

Also a tiny detail:

Also imp to have the compiler (whaterver compiling script or command you have) mapped to a certain key binding without silent, for for debugging.
