# Setting up Inverse Search with Neovim, VimTeX and Zathura

Note 06.01.2023: With the release of VimTex 2.8, you probably don’t need to do this any more. See :help vimtex-synctex-inverse-search.

There are many reasons to write LaTeX in Vim instead of the more “traditional” LaTeX editors. Maybe you want to type long equations quickly with the help of UltiSnips, or you just want to make the most of Vim’s many features. VimTeX is a plugin for Vim (and Neovim) which allows for the easy authoring of LaTeX files using Vim, with useful features such as autocompilation, and Zathura is a minimalist, highly customisable document viewer with Vim keybindings by default.

Setting up inverse search allows you to jump to a point in your .tex file by Ctrl-clicking the corresponding place in your .pdf file, which can be especially useful for long documents.

First, install neovim-remote using pip3 install neovim-remote.

You next need to set NVIM_LISTEN_ADDRESS to /tmp/nvimsocket by adding export NVIM_LISTEN_ADDRESS=/tmp/nvimsocket to your ~/.bashrc, ~/.zshrc, or whatever the config file is for your specific shell. This allows, after having started a Neovim instance, the running of commands from other terminal windows, e.g. running nvr --remote file1 would open a file file1 in the Neovim instance. (I think Zathura takes care of setting NVIM_LISTEN_ADDRESS for you, but there is no harm in doing this anyway, plus it may be necessary for other PDF viewers, should you want to switch.)

Now, ensure synctex is enabled. There are various ways to do this, but the way I do this is by adding \synctex=1 to the preamble of the .tex document.

Add the following to your ~/.config/nvim/init.vim:

let g:vimtex_view_method = 'zathura'
let g:latex_view_general_viewer = 'zathura'
let g:vimtex_compiler_progname = 'nvr'


Add the following to your ~/.config/zathura/zathurarc:

set synctex true
set synctex-editor-command "nvr --remote-silent +%{line} %{input}"


After this, you should be able to Ctrl-Click on a part of the file in Zathura, and Neovim will go to that point in the .tex file.

Note that this will only work after a change has been made to the file, i.e. it won’t work if you just open the file and try to reverse search; you need to make a change and save it first.
