Auto load at startup

Auto load at startup

[Sébastien Kirche]

Hi,
for auto-loading elisp libraries at startup from a custom directory,
I though it was necessary to add something like

(add-to-list 'load-path "~/.my_elisp_dir/")

but it seems like emacs don't care of subdirs of my_elisp_dir.
Thus I have errors at startup if I add some

(require 'package)

if the named package is in a subdir.

But i put inside my_elisp_dir a file subdirs.el that *sould* have load 
these packages ?

Also, i found the following in the emacswiki :

,----[ Including subdirectories ]
|
| By default Emacs doesn't include subdirectories of a directory
| which is added to load-path. But you can do it by issuing a command
| in startup file:
|
| (normal-top-level-add-subdirs-to-load-path)
|
| which will add all subdirs of current directory. Note: current 
directory
| is not necessary that one, where your script is executed at the 
moment.
| So you first need to change directory to required one:
|
| (progn (cd "~/elisp") (normal-top-level-add-subdirs-to-load-path))
|
| In this example assumed that you want to add all subdirs of ~/elisp 
directory.

I tried this tip that seems to work, but I would like to understand why 
the subdirs.el fails/isn't sufficient.

Thanks for help

What exactly did you put in ~/.my_elisp_dir/subdirs.el that didn't work?

Well,
actually, i think after investigation that I could have fixed my 
problem.
It was mainly a mis-understand of behaviour of emacs about the 
load-path :
i first added the following in my .emacs :
,----
| (if (file-exists-p "~/.elisp/" )
|   (setq load-path (cons (concat "~/.elisp/" ) load-path))
| )
`----
and that subdirs.el in ~/.elisp :
,----
| (if (fboundp 'normal-top-level-add-subdirs-to-load-path)
|     (normal-top-level-add-subdirs-to-load-path))
`----

the lisp files that were in ~/.elisp were accessible, but i found that 
packages in subdirs were accessibles but not pre-loaded, that was what 
i mis-understood.

I corrected the following like this :
,----
| ; check either Emacs or XEmacs
| (defvar is-xemacs
|   (string-match "XEmacs" emacs-version)
|   "Variable interne differente de nil si on est dans XEmacs"
| )
|
| ; add my personal elisp directory to search path + preload
| (defvar my-elisp-path "~/.elisp" "Chemin vers mes packages elisp")
| (if is-xemacs
| 	(setq my-elisp-path (expand-file-name my-elisp-path))
| )
| (add-to-list 'load-path my-elisp-path)	
| (progn (cd my-elisp-path) (normal-top-level-add-subdirs-to-load-path))
`----
What do you think of that proposition ?

Thanks for any remark
Sébastien.
