Description

When trying to complete citations with bibtex, I was running into errors when I simply included the file name of the bib file. My bib files are located in my texmf tree directory, and are found by kpsewhich. However, in order for citation completions to work in vimtex I need to use the full path of the bib file.

E.g. merely having \addbibresource{somefile.bib} does not make the citation completion menu appear when I press <C-x><C-o>, but I need to include the whole path, \addbibresource{~/Library/texmf/bibtex/bib/somefile.bib}.

Steps to reproduce

1. nvim -u minimal.vim minimal.tex
2. Uncomment out the first bib file option "\addbibresource{somefile.bib}"
3. Go over to \cite{}
4. Try to complete citations using <C-x><C-o>

set nocompatible
let &runtimepath  = '~/test/vimtex,' . &runtimepath
let &runtimepath .= ',~/test/vimtex/after'
filetype plugin indent on
syntax enable
" Add relevant options and VimTeX configuration below.

\documentclass{minimal}
\usepackage{biblatex}

% \addbibresource{somefile.bib}
% \addbibresource{~/Library/texmf/bibtex/bib/somefile.bib}

\begin{document}

\cite{}

\end{document}

Expected behavior

The citation completion menu should pop up with all of the bibliography entries in somefile.bib

Actual behavior

There is no citation completion when using \addbibresource{somefile.bib}, but there is citation completion when using \addbibresource{~/Library/texmf/bibtex/bib/somefile.bib}.

However, compilation works on both versions without error and kpsewhich somefile.bib returns the location, the only issue is in completion.

Do you use a latexmkrc file?

No
