So what?  Most documents will still run through LaTeX nevertheless,
and if preview-latex finds that you have configured AUCTeX to run
pdflatex, current versions will just run latex for generating the
previews, nevertheless.

Two angles must be dealt with.  Angle 1 is that the Emacs part needs
to get away with batch operation.  If that is accomplished, other
converters can be dropped in as well.  Angle 2 is that all the
important information must be written out into PDF specials, which I
have no clue about.

An optional angle 3 would involve running GhostScript in damon mode
operation like we do it for PostScript: in that case, one would need
to know how, for example, GhostView can navigate freely through PDF
files.  This would probably be the most ambitious part, and it would
mostly obliterate the need for angle 1 as well (which we nevertheless
want to arrive at).

No, windows allow transparent windows. It has nothing to do with E.

You're recommending the OP start using e.g. Eterm or gnome-terminal with
their transparent background abilities, that's all.

More to the point, you totally lose the point of having emacs being an X
application: the mouse-interaction will be fubarred and there won't be any
scope for a toolbar, nor even for a graphical representation of the
menubar.

Some, of course, would say this was a good thing ;8)

Look into getenv:

    getenv is an interactive compiled Lisp function in `env'.
    (getenv VARIABLE)

    Get the value of environment variable VARIABLE.
    VARIABLE should be a string.  Value is nil if VARIABLE is undefined in
    the environment.  Otherwise, value is a string.

    This function consults the variable `process-environment'
    for its value.

There is also dired-do-chgrp which perhaps could be used (or suitably
modified for your purpose).

I have the following in ~/.emacs:

(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'latex-mode-hook 'turn-on-auto-fill)

I now want to set the fill-column differently for LaTeX files.

This doesn't do anything (I verified with C-h v that the value of 
fill-column is 70, the default):
(add-hook 'latex-mode-hook '('set-fill-column 100))

This gives an error when starting emacs:
(add-hook 'latex-mode-hook ('set-fill-column 100))

What's the correct syntax?


Also, once I've done that, can I set it differently for mail-mode and 
text-mode?

Thanks,
Adam
