I'm actually having trouble adding the following entry:
--8<---------------cut here---------------start------------->8---
\[[^]]*\<\(meta\)?label[[:space:]]*=[[:space:]]*{?\(?1:[^],}]+\)}?
--8<---------------cut here---------------end--------------->8---
I tested it with regexp-builder, it correctly matches the
metalabel={...} entries in my file.
But whether I add it through customize or with a (setq ...) command, it
doesn't seem to get picked up when I refresh the TOC buffer, either
through r or R.
Also, in tikz you can have label={...} keys, not only xlabel and
ylabel. They are currently picked by the latest version of your regexp
but I don't see how to exclude them without defining a list of
environments where reftex shouldn't look for labels which I imagine
would imply a lot of changes in the code.
Here is an example of such a tikzpicture label:
--8<---------------cut here---------------start------------->8---
\begin{tikzpicture}
\node [label={\RayonArc:$\theta$}] at (\AngleMilieu:\RayonArc) {};
\node [shape = vector out,label=left:$\vvEz $] {};
\end{tikzpicture}
--8<---------------cut here---------------end--------------->8---
Thanks for your help,
Julien.
