Not all reftex commands within latex block generate appropriate message

Not all reftex commands within latex block generate appropriate message

[Alain.Cochard]

Issued after 'org-edit-special' within a latex block (like the one
below) the command 'reftex-toc' generates the dreadful

   reftex-TeX-master-file: Wrong type argument: stringp, nil

Only after some debugging time and trying

   reftex-label

did I understand what I presume is the reason:

   reftex-access-scan-info: RefTeX works only in buffers visiting a file


#+begin_export latex
\documentclass{article}
\begin{document}
\section{1}
\section{2}
\end{document}
#+end_export

I think this is indeed likely to be the reason.

Similar issues arise with, for instance, ledger in that some of the
capabilities of ledger-mode assume that there is a file behind the
buffer.  Not sure there is any solution to this other than tangling your
code to a file and visiting that file.

Thanks for the confirmation.  I was hoping that someone can arrange so
that the self explanatory message is shown each time, not the cryptic
one :-)

I'd say that it is reftex bug. It is generally expected that major modes
do work in non-file buffers in Emacs.

Thanks.  I have sent a message to bug-auctex@gnu.org.
