font-locking mysteries

font-locking mysteries

[Christian Gudrian]

Hello, there!

I am using Emacs 21.3.50 on WinXP-Cygwin with AUCTeX version CVS-5.383. 
  I have configured my LaTeX environment so that Emacs automagically 
inserts the characters `«' and `»' when pressing `"' on the keyboard. 
Usually, AUCTeX highlights text enclosed in `«' and `»'.

However this only works correctly, when entering `«' and `»' directly 
via Alt-Gr-Y and Alt-Gr-X.  When these quotes are inserted automagically 
they do not triger font-locking, instead I need to revert the buffer for 
font-locking to become active for the quoted text.

Which part needs tweaking?  Which handles have to be turned?

So it's an AUC-TeX issue.  Thanks!

Unfortunately Emacs does not allow the creation of mail buffers under 
Cygwin, since the buffer file name contains characters which might not 
be used on Windows file systems, I suppose.

Is there a different way of submitting a bug report?

Ugh, what?!?

You should report that, whatever it is, as a bug.

If you have a gnus session active and mail-user-agent set to
gnus-user-agent, then the buffer file name might be different when
calling mail.

Well, if I say M-x mail I get an error message saying

`Opening output file: no such file or directory, 
/home/Gudrian/#*mail*#1660Va0#'

Asterisks are no good in file names that are meant to be stored on file 
systems by Microsoft...  Which makes me wonder whether that would work 
on *nix systems.  Anyway I never got an error message like that on 
FreeBSD, and given the fact that CVS Emacs doesn't compile on Cygwin at 
the moment it might just be the combination of Cygwin and Emacs which 
causes this behaviour.  Never bothered me though, since I do not use 
Emacs for mailing.

Let me guess:

M-x report-emacs-bug

which in turn will try to open a mail buffer, right? :)

No, I'm sorry.  Don't bother.  I might dive into that some time later. 
But it's not worth it at the moment.  After all it's just a minor 
font-locking problem I was originally dealing with.

Is there a function which formats the mail buffer name?  Perhaps I can 
alter it in a way that will make reporting bugs work.

I was just wondering since I hardly ever use them.  Obviously there are 
reasons for some (so called) OSs not to allow *s in file names.

That is just the autosave file.  It won't get created before the
buffer.  The buffer should appear just fine.

If not, do
M-: set-variable RET auto-save-default RET nil RET
before doing your bug report.

Certainly.

If you refuse to apply any proposed measure, you can't use the
predefined bug reporting methods to report a problem with the
predefined bug reporting methods.

I should have thought that obvious.

And it is a major bug reporting problem you are dealing with now.

That does it.

If all major problems could be worked around that easily.

Thanks for your help,

By disabling autosave?  No thanks, I value my edited files.  You
should really just do this for the sake of being able to report the
bugs.  And certainly to report the bug reporting bug!

At first I wrote 'could be solved'.  But then I made up my mind and 
chose 'could be worked around' to point out, that it's nothing more than 
just that: a work around.

BTW, auto saving itself works perfectly for ordinary buffers.

Been there.  Done that.
