My solution -- since I now want to go deeper in Org (and would like to be able
to code, help, test, patch, etc.) -- would not address your last point (no
restart of Emacs), but is easy to use.
I'm using the following to add subdirectories to the `load-path' variable
(see [¹]):
--8<---------------cut here---------------start------------->8---
(defun my/add-to-load-path (this-directory &optional with-subdirs recursive)
"Add THIS-DIRECTORY at the beginning of the load-path, if it exists.
Add all its subdirectories not starting with a '.' if the
optional argument WITH-SUBDIRS is not nil.
Do it recursively if the third argument is not nil."
(when (and this-directory
(file-directory-p this-directory))
(let* ((this-directory (expand-file-name this-directory))
(files (directory-files this-directory t "^[^\\.]")))
;; completely canonicalize the directory name (*may not* begin with `~')
(while (not (string= this-directory (expand-file-name this-directory)))
(setq this-directory (expand-file-name this-directory)))
(message "Adding `%s' to load-path..." this-directory)
(add-to-list 'load-path this-directory)
(when with-subdirs
(while files
(setq dir-or-file (car files))
(when (file-directory-p dir-or-file)
(if recursive
(my/add-to-load-path dir-or-file 'with-subdirs 'recursive)
(my/add-to-load-path dir-or-file)))
(setq files (cdr files)))))))
--8<---------------cut here---------------end--------------->8---
and I'm using:
--8<---------------cut here---------------start------------->8---
(defvar local-site-lisp-directory
(concat (or (getenv "LOCAL_SHARE")
"~/Downloads") "/emacs/site-lisp/")
"Name of directory where additional Emacs goodies Lisp files (from the
Internet) reside.")
(my/add-to-load-path local-site-lisp-directory 'with-subdirs 'recursive)
--8<---------------cut here---------------end--------------->8---
to load everything under ~/Downloads/emacs/site-lisp/. Everything but the
directories beginning with a dot.
So, I could have there:
- org-mode-git
- .org-mode-6.35
- .org-mode-6.34
for example. And only the current Git version of org-mode would be loaded at
Emacs startup.
For switching to Org-mode 6.34, just remove the dot in front of the directory
name, add a dot to the current Org directory, and relaunch Emacs.
Note, though, that I'm considering the use of `.el' files only, not byte
compiled ones. But does that make a big difference?
Hope this helps.
Seb
