Setting file-local list variables

Setting file-local list variables

[Mark Elston]

(I sent this to the AucTeX mailing list as well but since this is
possibly more an Emacs issue I thought I would send it here as well.)

I have been trying to set a file local variable for a LaTeX file
I have been working on and it just doesn't seem to stick.  In
particular I am trying to set LaTeX-verbatim-environments.  I am
using the fancyvrb package and have developed some specific verbatim
environments and want AucTeX to deal with them appropriately.  These
environments are specific to the file I am working on and, so, I don't
want to customize AucTeX to *always* recognize them since they won't
appear in any other files.

However, when I put the following in my .tex file:

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% LaTeX-verbatim-environments: ("verbatim" "verbatim*" "CodeListing" 
"OldCodeListing" "NewCodeListing")
%%% End:

I get a warning when loading the file that setting the variable may
not be safe.  I hit 'y' to apply the local variables list and the file
is loaded.  However, even though I can look at the variable and see that
it is set appropriately, AucTeX doesn't handle these environments as
verbatim environments.

If I customize the variable then it works fine.

How do I set this variable so that it applies to the file?

Have you tried quoting?  I still get the same thing, when I try the
following document:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
\documentclass{article}
\begin{document}

\begin{verbatim}
Kiss this!
\sin(x)

\end{verbatim}
\begin{equation}
  \label{eq:1}
  \sin(x)
\end{equation}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% LaTeX-verbatim-environments: '("verbatim" "verbatim*" "CodeListing" "OldCodeListing" "NewCodeListing")
%%% End:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

@someone-who-knows: Does this just come up when a new variable is
introduced in a local variables list?

@OP: If so, what's wrong with marking the variables as safe and applying
them in the future (!)?

Yeah, it didn't work for me either.

I tried that, too.  It didn't work either.

I wonder if this is an AucTeX thing.  The AucTeX manual says that this variable controls
the verbatim-like environments.  However, in the help for the variable it says:



        LaTeX-verbatim-environments is a variable defined in `latex.el'.
        Its value is 
        '("verbatim" "verbatim*" "CodeListing" "OldCodeListing" "NewCodeListing")

        Local in buffer AddingStateMachineToClass.tex; global value is 
        ("verbatim" "verbatim*")

        Documentation:
        Verbatim environments.

        Programs should not use this variable directly but the function
        `LaTeX-verbatim-environments' which returns a value including
        buffer-local keyword additions via
        `LaTeX-verbatim-environments-local' as well.


I don't know if this means that setting the variables is the wrong way to go.

BTW, I have also tried setting 'LaTeX-verbatim-environments-local' both as a list
and a quoted list as well.  That, too, doesn't work.

I wouldn't expect it to work for you, if it failed for me ;)

What do you mean it didn't work?  Did you enter "!" when prompted?  From
the *Help* you show, it seems that it did "work" as far as setting the variable.

That's Emacs being a self-documenting editor.

Hmmmm...what is it you're trying to accomplish?  Refresh my memory.

Glad to help, if only for discussion's sake :)

It didn't apply these variables to the buffer as it was loaded.  Rather,
it didn't result in the proper faces being applied to the appropriate
regions.

It turns out it *is* an AucTeX thing.  See below.

I'm trying to set a list variable in a buffer so that AucTeX can apply
the proper faces to verbatim-like regions in my text.  I wound up with
the following:

%%% eval: (eval-after-load "latex" '(progn (add-to-list 'LaTeX-verbatim-
environments "CodeListing")(add-to-list 'LaTeX-verbatim-environments 
"OldCodeListing")(add-to-list 'LaTeX-verbatim-environments 
"NewCodeListing")))

Unfortunately, this still isn't quite right since it applies the 
changes *globally* and doesn't affect the *first* load of a file with
this line in it (I have to close the file and reopen it to get the
changes applied).

It turns out that these environments are created only for one LaTeX
file I am working with so I don't want to put this in my custom.el
forever.  Other files may have other verbatim-like environments to
make use of so I want this on a file-by-file basis.

Sigh.  Still looking for the best answer.
