Order in which hooks and defaults are applied, especially set-fill-column.

Order in which hooks and defaults are applied, especially set-fill-column.

[Adam]

My ~/.emacs contains the following:

...
;; AucTeX
(require 'tex-site)
(add-to-list 'auto-mode-alist '("\\.tex\\'" . latex-mode))
;; auto-fill for certain modes
(setq-default fill-column 70)
(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'latex-mode-hook 'turn-on-auto-fill)
(add-hook 'html-mode-hook 'turn-off-auto-fill)
(add-hook 'xml-mode-hook 'turn-off-auto-fill)
(add-hook 'latex-mode-hook (lambda() (set-fill-column 100)))
...


But when I open a LaTeX file, auto-fill is on and it wraps at 70.  HTML 
and XML files both open the way I want (with auto-fill off).  Is it 
possible to configure it to run the way I want -- wrapping LaTeX at 100, 
not wrapping HTML and XML, and wrapping everything else at 70?

Thanks,
Adam

I don't think the problem is that the hooks are run in the "wrong"
order, but that latex-mode-hook isn't run at all -- otherwise, why would
the default value of fill-column be in effect?  (You could test that
with `C-h v fill-column'; if it doesn't say "Local in buffer foo.latex",
it was never set.)

Perhaps the name of the hook is tex-mode-hook, or Tex-mode-hook, or
LaTex-mode-hook.

The default LaTeX editing mode in Emacs is `latex-mode' and runs
`latex-mode-hook'.  The mode offered by AUCTeX is called `LaTeX-mode'
and runs `LaTeX-mode-hook'.

My ~/.emacs now includes the stuff below and I believe everything works 
the way I want.

...
;; AucTeX
(require 'tex-site)
(add-to-list 'auto-mode-alist '("\\.tex\\'" . LaTeX-mode))
;; auto-fill for certain modes
(setq-default fill-column 70)
(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'LaTeX-mode-hook 'turn-on-auto-fill)
(add-hook 'html-mode-hook 'turn-off-auto-fill)
(add-hook 'xml-mode-hook 'turn-off-auto-fill)
(add-hook 'LaTeX-mode-hook (lambda() (set-fill-column 100)))
...

Thank you very much for your help!
