Description:

The search path for .el files in xemacs is not configured properly, many directories are missing.

xemacs-21.5.29-2

Steps to reproduce:

Write in test-lazy-shot.el the following:

(custom-set-variables
'(gnuserv-visit-hook (quote (lazy-lock-mode)))
'(lazy-lock-mode nil nil (lazy-lock))
'(lazy-lock-stealth-verbose nil)
'(lazy-shot-mode t nil (lazy-shot))
'(lazy-shot-verbose nil)
)

Then try: xemacs -debug-init -user-init-file $PWD/test-lazy-shot.el

It fails with Cannot open load file: "lazy-shot"
However xemacs-all-packages installed it, in /usr/lib/xemacs/xemacs-packages/lisp/edit-utils/lazy-shot.el

On other distros it works. The difference is that C-h v load-path shows only
"/usr/lib/xemacs/xemacs-packages/lisp" and a few other site-lisp dirs, while on other distros load-path contains many many directories, including all the subdirs of that base directory. E.g. the subdir edit-utils is missing for this one to work, but all other subdirs are missing too. I have no idea where's the code that sets the default load-path though, and why it would be different between distros...
This task depends upon

Why was this bug closed as fixed? I upgraded to 21.5.29-3 and the bug is still there, and
http://repos.archlinux.org/wsvn/packages?op=comp&compare[]=%2Fxemacs%2Ftrunk@63771&compare[]=%2Fxemacs%2Ftrunk@96361 doesn't show any change relating to the load-path.

Please have another look at this issue.

With which distro do you compare?
Comment by David Faure (dfaure) - Tuesday, 09 November 2010, 14:30 GMT
Well I'm comparing with kubuntu for instance, but I know for sure that my colleagues using OpenSUSE don't have to set the load-path by hand either.

OK I just had a deeper look on kubuntu: apt-get source xemacs21, and the diff.gz includes a xemacs21-21.4.22/debian/00debian.el which says

+(setq load-path
+ (append
+ (dir-and-all-good-subs
+ (expand-file-name "~/.xemacs/xemacs-packages"))
+ (dir-and-all-good-subs
+ (expand-file-name "~/.xemacs/packages"))
+ (list (concat "/etc/xemacs" debian-xemacs-major-version))
+ '("/etc/emacs")
+ (list (concat "/usr/local/share/emacs/xemacs-" debian-xemacs-version
+ "/site-lisp"))
+ '("/usr/local/share/emacs/site-lisp")
+ `(,@(dir-and-all-good-subs "/usr/local/lib/xemacs/site-lisp")
+ ,@(dir-and-all-good-subs
+ (concat "/usr/share/xemacs/site-lisp-"
+ debian-xemacs-major-version "/"))
+ ,@(dir-and-all-good-subs "/usr/share/xemacs/site-lisp/")
+ ,@(dir-and-all-good-subs
+ (concat "/usr/share/xemacs" debian-xemacs-major-version
+ "/site-lisp/"))
+ )
+ load-path
+ '("/usr/share/emacs/site-lisp")))

And above all this there's a (setq module-load-path '("/usr/lib/xemacs/site-modules")), not sure if related.

No idea how "upstream" xemacs is supposed to be used out of the box, with tons of missing dirs in load-path...

Can you please attach that diff.gz or send a link?
Comment by Stefan Husmann (stefanhusmann) - Friday, 15 April 2011, 08:04 GMT
Maybe Sergey can send some light on this.

I think we shoud provide a file $pkgdir/usr/share/xemacs/xemacs-packages/lisp/site-start.el in the package xemacs-all-packages with the relevant paths added to the load path, i.e.

(setq load-path
(cons "/usr/lib/xemacs/xemacs-packages/lisp/edit-utils"
load-path))

This has to be done for every subdir that is missing.

I added site-start.el into xemacs-all-packages-20110418-1-any.pkg.tar.xz. Please check it.
(On my machine it does not load site-start.el automatically, but after load-file it works)
