Vimtex: Does bibliography completion cache some results?

Created on 24 Sep 2019 · 2Comments · Source: lervag/vimtex

Hi lervag, I have encountered this issue with completion of citations. Generally, I have noted that it affects very large bib files, but it seems I was able to create a small reproducible example.

Issue
Completion for bib file does not work as expected. It seems that the results are somehow cached.

minimal.vim

call plug#begin('~/.local/share/nvim/plugged')
Plug 'lervag/vimtex'
call plug#end()

" Vimtex options go here
let g:vimtex_view_method = 'zathura'
let g:vimtex_compiler_progname = 'nvr'

minimal.tex

\documentclass{article}
\begin{document}
This is an attempt to reproduce the issue
\cite{bar
\bibliography{bib2.bib}
\bibliographystyle{plainnat}
\end{document}

bib2.bib

@article{foo_2017,
    title = {Foo},
    journal = {Journal},
    author = {fooauthor},
    year = {2017},
}

@article{bar_2017,
    title = {Bar},
    journal = {Journal},
    author = {barauthor},
    year = {2017},
}

@article{none_2017,
    title = {Another title containing Bar},
    journal = {Journal},
    author = {barauthor},
    year = {2019},
}

Commands/Input

Open file with nvim -u mimimal.vimrc minimal.tex
Insert mode at the end of line 4 in minimal.tex, and call completion with <C-X><C-O>, which works as expected providing suggestions for bar_2017 and none_2017
Insert a new line and type \cite{f, then call <C-X><C-O>

Observed Behaviour
The pop-up shows again suggestions for bar_2017 and none_2017.

Expected Behaviour
Complete with foo_2017
