file/local variables (and auctex?)

file/local variables (and auctex?)

[thorne]

Hello.  I am working on a file and in its current incarnation it has a
file variables (first) line that looks like this:

% -*- fill-column: 60; -*- 

and a local variables (last) section that looks like this:

% Local Variables: %
% mode:latex %
% mode:longlines %
% tab-width:5 %
% tex-open-quote:"\"" %
% tex-close-quote:"\"" %
% indent-tabs-mode:nil %
% indent-line-function:insert-tab %
% End: % 

The problem:  latex mode and longlines do turn on and everything works
except setting fill-column and setting the tex open/close quote
string.  C-h v fill-column RET tells me it is set to 68 instead of
60.  Stranger, is that the tex open/close quote string tells me (when
i do C-h v) that they _are_ set correctly... yet when i acually type
a quote in the buffer, it inserts the default tex quotes.  I am
baffled.  Can anyone clue me in on what may be wrong?  

[This is GNU Emacs 22.0.92.1 (i686-pc-linux-gnu... )]

Thanks!

There is some spurious whitespace at the end of the last line.  This
prevents the whole stanza from being processed since the suffixes do
not match.

You specified to call LaTeX mode in the local variables stanza.  This
mode will be called after `fill-column' is set and call
`kill-all-local-variables' which kills off the local value of
`fill-column'.  Solution: Set all variables in the local variables
stanza _after_ specifying the major mode.

The variables in AUCTeX are called `TeX-open-quote' and
`TeX-close-quote', not `tex-open-quote' and `tex-close-quote'.

Yeah, wow i actually found that last night and sure enough, it has an
effect.  That trailing whitespace would have an effect does not
seem... ideal.

Yeah, thanks.  I got it more or less fixed.

Wow.  So sure enough, i do have a variable called `tex-open-quotes'
and another one called `TeX-open-quotes'.  That does not seem to me to
be... ideal.

Well, it doesn't matter.  I think i am officially giving up on doing
what i want to do with either troff or LaTeX.  But thank you anyway.
When my next avenue of approach fails to pan out, maybe i will come
back to LaTeX.

That would have caused a "Local variables list is not properly
terminated" error.  In the particular case the suffix is " %" and
matches, the trailing space being ignored.

I actually got this very error when copying the lines above to a file
and opening it.

Indeed - I was confused because the OP didn't mention it the first time.
It's due to the "$" in

	  (let ((suffix
		 (concat
		  (regexp-quote (buffer-substring (point)
						  (line-end-position)))
		  "$"))

and I stand corrected.  Maybe we should write

	  (let ((suffix
		 (concat
		  (regexp-quote (buffer-substring (point)
						  (line-end-position)))
		  "[ \t]*$"))

instead.
