'\lv' opens new instance of okular

[ZhiyuanLck]

Promblem

I'm using gvim with vimtex and the pdf viewer is okular obtained from chocolatey.

With arbitrary *.tex files the first call of :VimtexCompile causes okular to be lauched once with a popup saying "There is already a unique Okular instance running. This instance won't be the unique one." Enter "ok" and there is actually one instance. But when I use \lv to perform a forward search, the same popup occur. After "ok" is pushed, a new instance is created.

Viewer set in .vimrc

    let g:vimtex_view_general_viewer = 'okular'
    let g:vimtex_view_general_options = '--unique file:@pdf\#src:@line@tex'
    let g:vimtex_view_general_options_latexmk = '--unique'

[lervag]

Is this the same as #1364? If so, it should have been fixed recently. Can you confirm that you are on latest version of vimtex?

[ZhiyuanLck]

Not the same. I've read #1364 carefully and sure the code causing the problem in #1364 has been removed. It is when I call <plug>(vimtex-view) that the similar problem occurs.

[lervag]

I can not reproduce your problem, sorry. Can you specify a full minimal example, similar to this, and explain the steps required to reproduce?

[ZhiyuanLck]

Ok, I'll try it soon. I guess gvim has a strange reaction with xelatex.

[ZhiyuanLck]

Sorry, I'm late!
Here is the minimal example.
_vimrc

set rtp+=~/.vim
call plug#begin('~/.vim/bundles')
    Plug 'lervag/vimtex', {'for': ['tex', 'plaintex', 'bst']}
    let g:tex_flavor='latex'
    let g:vimtex_view_general_viewer = 'okular'
    let g:vimtex_view_general_options = '--unique file:@pdf\#src:@line@tex'
    let g:vimtex_view_general_options_latexmk = '--unique'
call plug#end()

test.tex

\documentclass{article}
\begin{document}
	hello
\end{document}

No .latexmkrc.

1. Run gvim test.tex and then :VimtexCompile. Then a popup occurs saying "There is already a unique Okular instance running. This instance won't be the unique one." Push the ok button and then a new instance of Okular is created.
2. Run :VimtexView, and then come with the same popup. Push the ok button, an another new instance is created. Hence then there are two windows of Okular.

[lervag]

Ok, I still can not reproduce.

Can you give me the output of :VimtexInfo when you've opened the minimal example?

Further, can you specify which system you are on? OS/Distribution, (g)vim version and okular version. Also, latexmk version may be relevant.

Thank you for helping me tirelessly. Below is the related information.

[lervag]

Thanks. I'm sorry to say that I can't be of much more help. I don't use Windows, and so I can't look into this directly. Okular works as expected on Linux. I was not aware that Okular was also available on Windows. In any case, have you tried to use the SumatraPDF viewer? I know that it should work quite well on Windows.

[ZhiyuanLck]

Thanks. I have tried SumatraPDF, and it has some little trouble reloading changed file, so I tend to okular. Actually the case in this issue is trivial and I have tried to use vimtex in manjaro. Whatever, so thankful to your help!

[lervag]

Happy to help, and sorry I could not be of more help. :)

[bernwo]

I also have the same exact problem on native windows (not WSL). My nvim info (installed using pre-built binary for Windows):

NVIM v0.9.0
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

and I'm running Okular version 22.12.1 straight from the Windows Microsoft Store (official by KDE).

[lervag]

I understand that it is annoying, but I sorry to say that I still don't have anything to add to my earlier statements on this matter.

[bernwo]

Fair enough. I will just use SumatraPDF which seems to work fine. Thanks!
