AFAIK, there is no variable default-directory-alist - at least, my
emacs does not know anything about it.
What you want is to change the default directory of the agenda buffer.
When the agenda buffer is created, org-agenda-mode is called to set
the major mode. Most major modes (including org-agenda-mode) define
hooks: a hook is a variable that holds a list of functions. The mode
calls each function in the hook when it is enabled. So the trick
is to add a function to the appropriate hook. Typically something
like this will suffice:
(add-hook 'org-agenda-mode-hook (function (lambda () (setq default-directory
org-directory))))
The only problem is where to add this line of code: if you add it to .emacs
or some other initialization file, you might get an error because
org-agenda-mode-hook is not defined yet. One way to get out of the
chicken/egg situation is to load org-agenda before you add the function
to the hook. Another way is to eval the above "on demand" when org
agenda is loaded:
(eval-after-load "org-agenda"
(quote
(progn
...
(add-hook 'org-agenda-mode-hook (function (lambda () (setq
default-directory org-directory)))))))
(the progn is there in case you have to do more than one thing when
loading the agenda: if you only have one thing, just remove the
ellipsis). This can safely be put into an initialization file like
.emacs.
You should also read the doc for add-hook (C-h f add-hook <RET>) and for
whatever hook variable you are modifying (e.g. C-h v
org-agenda-mode-hook <RET>: there are some fine points in add-hook that
I have not gone into above - otoh, org-agenda-mode-hook is bog-standard.
HTH,
Nick
