No completion for bibliographical entries

[manuel-uberti]

Hi,

I updated Digestif yesterday by removing the .digestif directory and re-running digestif from the command line, but I cannot complete bibliographical entries any more.

This is a small recipe to reproduce the problem:

• mkdir /tmp/test-completion
• create a biblio.bib file with the following content:

@Book{test,
  author       = {testy, test},
  title        = {This is a test},
  date         = 2022,
  publisher    = {Test Press}
}

• create a test.tex file with the following content:

\documentclass[12pt, oneside]{book}

\begin{document}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

• emacs -Q
• M-x eglot RET
• after \begin{document}, try inserting \cite{te and press TAB (or M-x completion-at-point)

This is the content of the Eglot events buffer:

I am using GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.16.0) of 2022-12-31

For the sake of completeness, I have a more complex .tex file with this at the top:

\usepackage[backend=biber, style=ext-authoryear, giveninits=true]{biblatex}
\addbibresource{biblio.bib}

By working in this file is where I experienced the problem.

[manuel-uberti]

BTW, not sure if this is related, but M-. on \cite or \textcite results in: xref--not-found-error: No definitions found for: LSP identifier at point.

(Happy new year!)

[manuel-uberti]

Another debug update: hard resetting to commit f1b4202 makes completion and M-. work again.

In your original example, I need to add \bibliography{biblio} somewhere to the file, but otherwise it works as expected.

There is a simple integration test for citations on the CI, so if there was a regression it must be a more subtle issue.

[manuel-uberti]

In your original example, I need to add \bibliography{biblio} somewhere to the file, but otherwise it works as expected.

It does not work for me though with the following file:

\documentclass[12pt, oneside]{book}

\bibliography{biblio}

\begin{document}

\textcite{te|}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

Where | is the cursor where I try to complete. Probably something related to recent Emacs changes on master?

[astoff]

Okay, the last example doesn't work because \textcite is defined in biblatex and the file doesn't have the corresponding \usepackage call (so \textci TAB also doesn't complete the command name). But when I add \usepackage{biblatex} all is fine again.

[manuel-uberti]

I added \usepackage{biblatex} to the example, but still nothing for me here. Eglot event buffer says:

(:jsonrpc "2.0" :id 2 :method "textDocument/completion" :params

	   :context

[server-reply] (id:2) Tue Jan  3 13:46:03 2023:
(:result
 []
 :jsonrpc "2.0" :id 2)

This is so weird.

Also, sorry to waste your time on something that seems to be happening only here. :)
