[AUCTeX] Referencing labels with refstyle.sty

[Alan Ristow]

Hi,

I often use refstyle.sty for managing cross-references. Since there 
doesn't seem to be a refstyle.el anywhere, I'm trying to modify my 
.emacs file to get RefTeX to insert references that are formatted for 
it. Without going into too much detail about refstyle itself, when I have:

\label{fig:foo}

it lets me write:

\figref{foo}

to mean:

Figure~\ref{fig:foo}

It has similar functionality for tables, equations, sections, chapters, 
etc., but once I have set up for one I should be able to easily extend 
it to the others. Focusing only on figures for the moment, I first tried 
this:

(setq reftex-label-alist
      '(("figure"   ?f "fig:"  "\\figref{%s}"  caption nil)))

This gets me halfway there, inserting \figref{fig:foo} rather than the 
\figref{foo} that I would like. Not being much of a Lisp programmer, 
after some struggle I came up with

(setq reftex-label-alist
      '(("figure"   ?f "fig:"  reftex-format-ref-function  caption nil)))

(defun reftex-format-ref-function (label default)
  (concat "\\" (replace-match "ref{" nil nil label ":") "}")
)

My intention here was to take the "fig:foo" label and replace ":" with 
"ref{", leaving me with "figref{foo", which I then concatenate between 
"\\" and "}" to give me "\\figref{foo}". In theory, anyway -- it doesn't 
work, telling me "reftex-reference: Wrong type argument: stringp, 
reftex-format-ref-function" when I try to insert a figure reference via 
C-c ) f.

I've done enough programming in enough languages to suspect that this is 
really a rather simple task, but thanks to my poor Lisp skills I'm 
finding myself totally lost. I think I need some help. Am I even close 
to a reasonable solution?

Thanks,

Alan
