Okay, let's try to clarify situation and to sort out different errors. > On Wed, Aug 11, 2021 at 10:43 AM Vladimir Lomov <[email protected]> wrote: [...] >> Besides, this in NOT an ERROR!

No wonder that bibtex warned me about missing '\bibdata' command (you may found that in that case running 'C-c [' would give message in minibuffer: "No valid bibliography..."; evaluating verbatim block wouldn't have 'bib' part). Let's compare the 'doc-samp3.ltx' document with following 'doc-samp.ltx' and 'doc-samp2.ltx' ones: %%% doc-samp.ltx ------------------------------------------------------------------------------ \documentclass{article} \usepackage{natbib} \begin{document} Sample text. Cite: \cite{test:2021aug}. \begin{verbatim} (insert "\n" (format "%S" (symbol-value reftex-docstruct-symbol))) \end{verbatim} Another cite: \cite{test2:2021aug}. \bibliographystyle{plainnat} % \bibliography{sample.bib} \bibliography{/home/vladimir/tmp/test/emacs/sample.bib} \end{document} %%% Local Variables: %%% TeX-master: t %%% End: ------------------------------------------------------------------------------ %%% doc-samp2.ltx ------------------------------------------------------------------------------ \documentclass{article} \usepackage{natbib} \begin{document} Sample text. Cite: \cite{test:2021aug}. \begin{verbatim} (insert "\n" (format "%S" (symbol-value reftex-docstruct-symbol))) \end{verbatim} Another cite: \cite{test2:2021aug}. \bibliographystyle{plainnat} % \bibliography{sample.bib} \bibliography{/home/vladimir/tmp/test/emacs/sample2.bib} \end{document} %%% Local Variables: %%% TeX-master: t %%% End: ------------------------------------------------------------------------------ The first document, 'doc-samp.ltx', cites some works and sets bibliography style (cp. with your "I found no '\bibstyle'" from blg file). Neither Emacs(+AUCTeX) nor (pdf)latex+bibtex would issue any warnings, document is typeset fine. The second document, 'doc-samp2.ltx', refers to a file that don't exist, so bibtex warns you and exited with error. You'll see the warning in minibuffer and excerpt from blg if run 'C-c C-l'. What would be correct way to check if something goes wrong: - make small complete example, like first document which cites some work, sets bibliography file with necessary information and bibliography style; - process it with latex engine and bibtex, check output (either in Emacs or just look into blg file), just look for error(s). If you do something weird, for example, citing a work but DO NOT PROVIDING bibliography information, latex as well as Emacs couldn't help you. It (latex) sees you want to cite something but it couldn't "expand" that into meaningful piece of text. The second document exactly shows that: if document refers to a file that don't exist bibtex will complain. What Arash was asking was another thing: he wanted to know if Emacs "knows" about the bibtex file, i.e. if it could parse your document, see the '\bibliography' command and could read it. The second document shows that if there is no such file Emacs(+AUCTeX+RefTeX) do not have 'bib' part.

Ahh, I thought it might be unclear but didn't ask. Emacs allows you to "evaluate" any part of buffer as Emacs Lisp code (see, e.g., "Operating on the Region" in Emacs manual), even code on a line (see "27.9 Evaluating Emacs Lisp Expressions") running "C-x C-e" on the line. > I try to eval the following in *scratch* buffer with `C-j', but obtain > `nilnil': > (insert "\n" (format "%S" (symbol-value reftex-docstruct-symbol))) > nilnil Do this in the buffer with open document. >> Of course I was able to typeset the document within Emacs as well as on >> command line.

OTOH, even I run the above step, I still can't find the .rel file. The .rel file was part of my configuration. I tried again and it works as you wrote. > Best, Hongyi --- WBR, Vladimir Lomov -- Never ask two questions in a business letter.
