I just setup Zathura to view PDFs. I'm using vim as the text editor, with vimtex as a plugin. I'm able to successfully view the PDFs, but the updates are delayed.
There seem to be two key difficulties: 1) I have to click on the PDF so the update is reflected 2) the update takes a few seconds to be reflected after clicking on the PDF.
Is there any way to resolve either or both of these issues?
Based on my personal experience, Mactex + Vimtex was quite slow when it comes to compile & preview processes. Until now, I still don't know why.
I am recently migrating to Visual Studio Code and used Vim & LaTeX Workshop extensions. It's working perfectly fine and fast. You should give it a try if you don't find any workaround on this later.
I am using vimtex for latex preview too. I am on macOS 10.15, and using skim instead of zathura to view PDFs and I don't have such an issue. You can give it a try to figure out whether the issues occur in zathura or vimtex. And you can also use :checkhealth in neovim (similar but different cmd for vim) to check if vimtex is working normally.
My settings are listed below:
" skim can be installed with brew
" vimrc
Plug 'lervag/vimtex', {'for': ['tex']}
"vimtex
let g:tex_flavor='latex'
let g:vimtex_view_method='skim'
let g:vimtex_quickfix_mode=0
set conceallevel=1
let g:tex_conceal='abdmg'
Happy vimming
