Re: key-val label style

[Wierdl Máté]

This really works now perfectly, Arash.  I do not even have to do C-c C-n.

Nope, the new one I posted here is more user friendly in terms parsing
the `label prefix' argument and making it available to AUCTeX and
RefTeX.  Putting things like this:

    %%% Local Variables:
    %%% mode: latex
    %%% TeX-master: t
    %%% eval: (add-to-list 'LaTeX-label-alist '("theorem" . "thm"))
    %%% eval: (reftex-add-label-environments '(("theorem" ?m "thm:" "~\\ref{%s}" nil ("Theorem" "theorem") nil)))
    %%% End:

in your .tex file is not necessary.  You can use diff on those styles to
see the changes.

This is the expected behaviour.  AUCTeX sees the \usepackage{my} macro
and tries to load my.el.  Save the next lines as my.el and put it in a
directory where AUCTeX can find it.

    (TeX-add-style-hook
     "my"
     (lambda ()
       (TeX-run-style-hooks "tcolorbox" "tcolorboxlib-theorems" "cleveref")
       (LaTeX-add-tcolorbox-lib-theorems-newtcbtheorems
        '("defn" "defn")
        '("thm" "thm")))
     :latex)

Now open your file again and hit `C-c C-n'.

Best, Arash
