Subject: [Reftex] Using the keyword label in a tikzpicture enviornment shows
 up incorrectly in reftex
Date: Thu, 23 Feb 2017 22:38:09 +0000

[Message part 1 (text/plain, inline)]

When using a tikzpicture enviornment as follows
  \begin{tikzpicture}
    \matrix[]{
                      % First row
      \node[scale=1.3,label=below:(a)]
{\input{./latex/CH4/dishole_schematic}}; &
      \node[label=below:(b)~$20$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_20}}; &
      \node[label=below:(c)~$40$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_41}}; \\ % end of
row
      \node[label=below:(d)~$160$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_160}}; &
      \node[label=below:(e)~$400$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_400}}; &
      \node[label=below:(f)~$800$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_800}};\\
            };
  \end{tikzpicture}

The label keyword used to label the node is picked up by Reftex as a
valid label when the ref command is invoked. Perhaps one can avoid
scanning for a 'label' keyword within a tikzpicture environment?

Nishan

RefTeX provides a variable for this purpose:

,----[ C-h v reftex-label-ignored-macros-and-environments RET ]
| reftex-label-ignored-macros-and-environments is a variable defined in ‘reftex-vars.el’.
| Its value is nil
| 
| Documentation:
| List of macros and environments to be ignored when searching for labels.
| The purpose is to ignore environments and macros that use keyval
| style label=foo arguments, but the label has a different meaning
| than a \label{foo}.  Standard \label{...} definitions are never
| ignored.
| 
| E.g., TikZ defines several macros/environments where [label=foo]
| defines the label to be printed at some node or edge, but it’s
| not a label used for referencing.
| 
| Note that this feature is only supported if you are using AUCTeX
| and the functions ‘TeX-current-macro’ and
| ‘LaTeX-current-environment’ are bound.  Also note that this
| feature might slow down the reftex parsing process for large TeX
| files.
| 
| You can customize this variable.
| 
| This variable was introduced, or its default value was changed, in
| version 24.4 of Emacs.
`----

You can customize this variable and add "node" if you want to ignore the
macro or "tikzpicture" for the entire environment.

Best, Arash

Thank you so much! Adding "node" to the value of a variable works.

You're welcome.  I close this issue.
