[AUCTeX] Customizing equation/figure label strings per document

[Ritesh Sood]

Hi all,

I want to change the equation/figure label strings in the following manner:

Environment                   Current (default)                       Desired 
equation                          eq:1                                                eq:P1-1
figure                                fig:1                                                fig:P1-1

 P1- stands for Part1-, and I'd like to have P2-, P3-, etc for different documents.  So the thing to do would be to write an AUCTeX style file and drop it in style/ subdir of the document directory. Only, I don't know elisp, and  couldn't make out what to do even after reading the AUCTeX and RefTeX documentation.

As an experiment, I changed

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "main"
%%% End:

to

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "main"
%%% LaTeX-equation-label: "eq:P1-"
%%% LaTeX-figure-label: "fig:P1-"
%%% End:

but that doesn't help either. As in C-( stil generates labels of the form eq:10, and there's an unsafe variable warning that pops up on starting emacs.

Can someone please give me an elisp code snippet that i can drop in style/ ?

Many thanks,
Ritesh
