How to properly load AUCTeX for Emacs 23+

How to properly load AUCTeX for Emacs 23+

[Sebastien Vauban]

Hello,

[This was posted first to comp.text.tex but did not receive any
answer -- trying here!]

Trying to make the smallest Emacs configuration needed for editing LaTeX
with AUCTeX (which has to work as well for Emacs 23), I came up with the
following:

--8<---------------cut here---------------start------------->8---
;; AUCTeX + preview-latex
(add-to-list 'load-path "~/.emacs.d/elpa/auctex-11.87.3") ;; <- update this!
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
--8<---------------cut here---------------end--------------->8---

from the current documentation found on
http://www.gnu.org/software/auctex/manual/auctex/Loading-the-package.html.

However,

- When loading a .tex file, I had different errors (such as
  "void-function font-latex-setup") which forced me to add different
  libraries to load during Emacs startup.

- `preview-latex.el' does NOT exist: it now (?) is `preview.el'.

Hence, this new configuration file which seems to work fine (so far):

--8<---------------cut here---------------start------------->8---
;; AUCTeX
(add-to-list 'load-path "~/.emacs.d/elpa/auctex-11.87.3") ;; <- update this!
(load "auctex.el" nil t t)
(load "font-latex.el" nil t t)
(load "tex-bar.el" nil t t)

;; preview-latex
(load "preview.el" nil t t)
--8<---------------cut here---------------end--------------->8---

Am I doing something wrong?  Is the doc NOT up-to-date?  Are both true? ;-)

Best regards,
  Seb

Your snippets indicate that you are using AUCTeX from ELPA.  In this
case, the smallest (and strongly recommended) configuration to load
AUCTeX properly is to have no configuration at all.

I've just created a new test user on my machine, fired up a fresh emacs
with it, installed auctex 11.87.4, and then edited a new tex file.
AUCTeX was loaded successfully and used in the resulting buffer, and
preview was also there (though I didn't test it because I just had a
terminal session).

Bye,
Tassilo

OK. Thanks for confirming.

Though, my question is more for people who would still use Emacs 23:
they don't have such an easy solution as for Emacs 24 -- though I now
see that, after downloading a custom package, they should be able to use
"package.el" (see http://www.emacswiki.org/emacs/ELPA#toc9).
