label completion in the \ref auctex macro

[Daniel Schmitt]

Using the auctex macro \ref I would excpect that the key completion
using TAB to offer all labels in the current document.

For example starting from this document:
\documentclass[a4paper]{article}

\begin{document}
\begin{figure}
dfdsj
\caption{eins}
\label{fig:eins}
\end{figure}
\end{document}

using copy and paste:
\documentclass[a4paper]{article}

\begin{document}
\begin{figure}
dfdsj
\caption{eins}
\label{fig:eins}
\end{figure}

\begin{figure}
dfdsj
\caption{zwei}
\label{fig:zwei}
\end{figure}

\end{document}

Now, fig:zwei is not offered in the completion list.

Labels that you did not let RefTeX insert itself become known to it
only when reparsing the document. Use the menu "Ref/Parse Document".

Daniel didn't use any RefTeX command, but he used `C-x RET \ref RET'.
After C&P, `M-: (LaTeX-label-list) RET' only shows fig:eins.
After `C-c C-n' (<LaTeX> <Multifile/Parsing> <Reset Buffer> /
TeX-normal-mode), `M-: (LaTeX-label-list) RET' shows the updated list.

As an end user not familiar with AUCTeX's internals, Daniel expected
that AUCTeX might know about the labels after running LaTeX on the
document. Is `C-c C-n' the best way to deal with this problem?

Bye, Reiner.

Probably yes. I don't think it would be a good idea to search the
whole file for labels every time a new reference is about to be added.
This could become very annoying in larger files.
