reftex: Figure Wrapper

 
 3.4.3 Figure Wrapping Macro
 ---------------------------
 
 Suppose you want to make figures not directly with the figure
 environment, but with a macro like
 
      \newcommand{\myfig}[5][tbp]{%
        \begin{figure}[#1]
          \epsimp[#5]{#2}
          \caption{#3}
          \label{#4}
        \end{figure}}
 
 which would be called like
 
      \myfig[htp]{filename}{caption text}{label}{1}
 
    Now we need to tell RefTeX that the fourth argument of the ‘\myfig’
 macro _is itself_ a figure label, and where to find the context.
 
      (setq reftex-label-alist
            '(("\\myfig[]{}{}{*}{}" ?f nil nil 3)))
 
    The empty pairs of brackets indicate the different arguments of the
 ‘\myfig’ macro.  The ‘*’ marks the label argument.  ‘?f’ indicates that
 this is a figure label which will be listed together with labels from
 normal figure environments.  The ‘nil’ entries for prefix and reference
 format mean to use the defaults for figure labels.  The ‘3’ for the
 context method means to grab the third macro argument: the caption.
 
    As a side effect of this configuration, ‘reftex-label’ will now
 insert the required naked label (without the ‘\label’ macro) when point
 is directly after the opening parenthesis of a ‘\myfig’ macro argument.
 
    Again, here the configuration in the customization buffer:
 
      [INS] [DEL] Package or Detailed   : [Value Menu] Detailed:
                  Environment or \macro : [Value Menu] String: \myfig[]{}{}{*}{}
                  Type specification    : [Value Menu] Char  : f
                  Label prefix string   : [Value Menu] Default
                  Label reference format: [Value Menu] Default
                  Context method        : [Value Menu] Macro arg nr: 3
                  Magic words:
                    [INS]
                  [ ] Make TOC entry    : [Value Menu] No entry
