loading site start before .emacs

loading site start before .emacs

[Micha Feigin]

Is it possible (and are there any issues) to make the site startup
files load before .emacs?

the desktop package seems to have problems with a lot of things if they
are not being loaded before desktop-read is called (I had issues with
ecp and now with preview-latex).

What issues?  preview-latex should work fine with desktop as long as
the respective autoloads for AUCTeX (in tex-site.el) and
preview-latex have already been defined.  This is not about _loading_
those packages, but about providing the necessary load information
when desktop-read decides to call upon them.

preview-latex is loaded automatically by the site file, so when I open
new latex files it is available.

When using desktop, unless I add (load "preview-latex") before
desktop-read then preview latex is not available for latex files opened
by desktop for some reason.

It could be some other problem with the setup though. IIRC it did brake
at some point, but I am not sure.

Obviously false.  preview-latex might be added into the load-path by
your site file, but that appears to be about it.

(load "preview-latex") does not load preview-latex.  Take a look at
that file's contents.  It merely defines the autoloads for
preview-latex so that any references to preview-latex functions will
then cause preview-latex to be loaded.  In addition, it enters the
preview-latex setup function into LaTeX-mode-hook.

In short: preview-latex is most certainly not loaded, and not even
initialized, automatically by the site file as you claim.

I think some further evidence that the OP may be on the wrong track is
that according to the emacs info pages, the site-startup.el file is
loaded BEFORE the users .emacs file

Thanks to the comments I found out my mistake. preview-latex is setup
properly. I just used bad examples for setting up mode hooks and used
setq instead of add-hood, which, if I understand correctly, removed
previous hooks, and thus removed the preview latex hook.

Here is something stolen from Kai G that might help, it leaves a
message in `*Messages*' when something loads:

Put it early in site-start.el
;; make loaded files give a message [from Kai]
 (defadvice load (before debug-log activate)
(message "(Tip from Kai G): Now loading: %s" (locate-library (ad-get-arg 0))))


Might unravel what is loading when.

Use site-start.el instead of default.el.
I find that default.el is almost never the right answer.
