citation (bib(la)tex) suggestion/completion disappears

[atticus-sullivan]

Issue
When inserting \cite{, the available keys from the .bib are suggested. But when starting to type to narrow the keys, the completion menu vanishes.

This is a follow-up from https://vi.stackexchange.com/questions/31129/coc-vimtex-bib-completion-strange-suggstions/31130#31130, but I've messed up with the initial post (sorry @ lervag again).

minimal.nvim

call plug#begin('~/.config/nvim/plugged')
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'lervag/vimtex'
call plug#end()

minimal.tex

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\addbibresource{testing.bib}

\begin{document}
\cite{k

\printbibliography
\end{document}

Observed Behaviour
Already described above. And see the demonstration:

Expected Behaviour
I'd expect that the menu stays visible and filters the entries by the text inserted.

Thanks for the issue report.

Before I try to reproduce this, I have a couple of minor comments:

• I've simplified your minimal vimrc file (note that you don't need g:tex_flavor and there is no VimTeX option named g:vimtex_complete_bib_simple). Can you test again with the simplified file?
• Note that the option g:vimtex_complete_bib.simple is 0 by default, in case that was the option you wanted to disable.

[lervag]

Also, as you probably understand, coc.nvim is implicitly loading a bunch of extensions. Can you list the extensions you have installed and perhaps remove every extension that is not relevant? I propose that you uninstall all extensions first, then reinstall coc-vimtex and test again. Let me know if you can still reproduce the issue.

[atticus-sullivan]

Note that the option g:vimtex_complete_bib.simple is 0 by default, in case that was the option you wanted to disable.

Yes I thought maybe this defaulted to the wrong value and this would be part of the issue I'm having (but anyway yes this was a typo in the option name)

The extensions I had installed were coc-calc, coc-clangd, 'coc-marketplace', coc-pyright, coc-ultisnips and of course coc-vimtex.

Now I had all coc extensions removed and using the really minimal .vimrc, but sadly the issue remains.

[lervag]

Ah, yes, sorry, I was also confused myself.

[lervag]

Sorry, I posted the reply before I was finished writing. So, the point is, as the docs say: When you want to use an autocomplete engine such as coc.nvim, it is better to use the simple option, so:

call plug#begin('~/.config/nvim/plugged')
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'lervag/vimtex'
call plug#end()

let g:vimtex_complete_bib = {'simple' : 1}

This should work better and more as expected, I think. Please test.

Yes now searching in the keys works. Thanks
