Hi
The latest auctex version 11.88 uses the following custom variable
(defcustom TeX-style-path
(let ((path))
;; Put directories in an order where the more local files can
;; override the more global ones.
(mapcar (lambda (file) (when file (add-to-list 'path file t)))
(append (list TeX-auto-global TeX-style-global)
TeX-auto-private TeX-style-private
(list TeX-auto-local TeX-style-local)))
path)
"List of directories to search for AUCTeX style files.
Per default the list is built from the values of the variables
`TeX-auto-global', `TeX-style-global', `TeX-auto-private',
`TeX-style-private', `TeX-auto-local', and `TeX-style-local'."
:group 'TeX-file
:type '(repeat (file :format "%v")))
the variable TeX-style-private is a name of a directory in which local
files dwell. Now I have set this variable in Xemacs and in GNU emacs via
custom (different custom files of course) to the value
/home/oub/tex/sty/auto
The issue is that TeX-style-path should contain also the value of
TeX-auto-private, /home/oub/tex/sty/auto
in GNU emacs it does, in Xemacs it does not.
Is there anything in the above definition Xemacs does not understand?
thanks
Uwe Brauer

No. Did you set TeX-auto-private to something other than `nil'? If
you did, is it possible that there's a function that checks that the
file/directory exists and resets it to `nil' if it doesn't exist?
Perhaps there's a typo in your init file or other custom setting?

Nope, its value is:

I tried it with and without the "/" at the end of the path.

Where you can see that the value of TeX-style-private is missing. The same
operation in GNU emacs leads to a correct value of TeX-style-path.
Tassilo suspects that it is the (add-to-list 'path file t)
call which might cause the problem, and has changed it.
A workaround is to customize directly TeX-style-path, which I am doing
right now. I was just curious to understand the reason behind this.

I'm getting confused. In the previous mail you mentioned both
TeX-auto-private and TeX-style-private, but claimed that
TeX-auto-private is missing. Now you're saying TeX-style-private is
missing, and its value is named "auto".
I guess that XEmacs isn't lying when you copy the output from C-h v,
but overall it's very hard to be confident of the reliability of your
reports.

Do you "(require 'tex)" before you set (eg, in custom.el) the
TeX-*-private variables? Traditionally, and probably in GNU Emacs,
custom was loaded before init, but there was a rash of people who had
reasons to load init before custom (typically they wanted to share
their init and custom files among different Emacsen and/or platforms,
and needed to compute values that were used by custom defaults), so
XEmacs switched the order about 10 years ago, because it's trivial to
load custom at the beginning of init when the default is to load
custom afterward, but essentially impossible to unload custom once
it's loaded.
What you should do is move the (require 'tex) late in init and put a
call to (load "/path/to/.xemacs/custom") *before* that. (It actually
probably doesn't matter where you put the `load' call as long as it's
before the (require 'tex).)
(Technically, to be perfectly sure you don't screw things up by
loading custom twice, you do
(progn
(load "/path/to/.xemacs/custom" t t)
(setq custom-file nil)
(add-hook 'after-init-hook
(lambda () (setq custom-file "/path/to/.xemacs/custom"))))
), but that's likely overkill.
Tassilo suspects that it is the (add-to-list 'path file t)
call which might cause the problem, and has changed it.
I don't think that's very likely. If that were the problem, I'd
expect you to get `nil' as the value of TeX-style-path. There's no
reason why the code you showed would treat TeX-*-private variables
specially, except that they are not given values until after you load
"tex".
Ie, if you comment out the defvar or defcustoms defining the
TeX-*-private variables, I bet you'll get a error of "unbound
variable" at init time.

Ok, I should not write reports when I am overworked, sorry.
I try to restart from scratch. I have deleted the relevant parts in my
custom file and restarted xemacs.
The relevant parts of my .emacs file look like that
(load-file "~/xemacs/init/xemacs_init.el")
(setq custom-file "/home/oub/xemacs/init/custom-init.el")
In the xemacs_init.el file there is a require to tex, well actually to
(require 'tex-site) which does all the necessary initializing.
Now all my auctex variables, which I have configured via custom, work
without problems.
So first to the value of the TeX-style-path variable
,----

|
| Value: ("/usr/local/var/auctex/"
"/usr/local/share/xemacs/xemacs-packages/etc/auctex/style"
"/home/oub/.emacs.d/auctex/auto" "/home/oub/.emacs.d/auctex/style"
"auto" "style")

`----
Now to the value of TeX-style-private variable
,----
|
| `TeX-style-private' is a variable declared in Lisp.

|

|

`----
This is the standard setting. So since my style files do not sit in
"/home/oub/.emacs.d/auctex/style" I change this variable (either by
substituting its value or my adding a new directory (it does not matter);
Say I add a directory via customize and its value is now:
,----
| `TeX-style-private' is a variable declared in Lisp.
| -- loaded from "tex"
|
| Value: ("/home/oub/.emacs.d/auctex/style" "/home/oub/tex/sty/auto")
|
| Documentation:

|
| These correspond to the personal TeX macros.
`----
However the value of TeX-style-path has *NOT* changed:
,----
| `TeX-style-path' is a variable declared in Lisp.
| -- loaded from "tex"
|
| Value: ("/usr/local/var/auctex/"
"/usr/local/share/xemacs/xemacs-packages/etc/auctex/style"
"/home/oub/.emacs.d/auctex/auto" "/home/oub/.emacs.d/auctex/style"
"auto" "style")

`----
I swear: I do the *same* steps in GNU Emacs (with different init files
in different directories) and the value of TeX-style-path changes.
What you should do is move the (require 'tex) late in init and
put a
call to (load "/path/to/.xemacs/custom") *before* that. (It actually
probably doesn't matter where you put the `load' call as long as it's
before the (require 'tex).)
Well the customization of all the other AUCTeX variable work, so your
advice sounds strange but I will try it out.
Result:
I does not help. Actually the problem on a practical level has an easy
fix, just customize directly the variable TeX-style-path variable.
I find it just curious that in xemacs the modification of the value of
TeX-style-private is not passed to TeX-style-path.
