(1) can I interactively call an e lisp function like "org-set-property" and
provide a single argument to it even if it expects 2, e.g.:
(call-interactively 'org-set-protertyt (vector "GRADE" ))? (I don't seem to
be able to pass ANY arguments via call-interactively so maybe I
misunderstand something fundamental).
(2) Is it possible to set the default value for interactive file selection
to something OTHER than the currect directory of the current buffer?
Something like:
(let
((base-dir "./Assignment1/"))
(org-attach--attach))
I'd like to set different base directories when attaching files to subtrees
of different first-level trees in a buffer. I guess I would set the value
for the base directory with a property.
thanks!
Matt

OK, I made some progress on this:
(let ((default-directory (concat default-directory "Assignment1/") ))
(call-interactively 'org-attach-attach))
However, I'd like to do something like:
(let
((parent-basedir nil))
(save-excursion
(outline-up-heading)
(setq parent-basedir (org-get-entry "BASEDIR")))
(let
((default-directory (concat default-directory parent-basedir) ))
(call-interactively 'org-attach-attach )))
But there are errors I don't understand in this code. Any hints? Thanks
again!

right, call-interactively uses the interactive form of the called
function to figure out the parameters and their values. Maybe you are
looking for something like this:
(defun set-foo-value (value)
(interactive
(list (read-string "prop value: " nil nil "<empty>")))
(org-set-property "foo" value))
(call-interactively 'set-foo-value)

well, I guess the errors are too secret to share them with us? The first
I can see is that org-get-entry doesn't need parameters. And the overall
structure looks strange, but that could be just me ;).
The reason for the current behaviour is the interactive form of
org-attach-attach. Ad hoc I have no idea how to change that. What I
would try is to (cd your-wanted-dir) before calling org-attach-attach.
Maybe a bit of cleanup if useful after calling the function.

The overall structure feels strange to me -- I just want a way of retaining
a temprary variable value in a let that also includes a temporary excursion
to the parent node. More on that shortly.

So it turns out that, like most interactive functions, org-attach-attach
uses the built-in read-file-name macro, which relies on the value of
"default-directory", which is buffer-local. By calling org-attach-attach
from inside a let statement, I can get the behaviour I want:
(let
((default-directory (concat default-directory "Galileo/")))
(org-attach-attach))
The problem now is that I need to access a property from the parent node
in order ot dynamically set the appropriate value for default-directory,
and I'm struggling to do that.
Here is a minimal test file:
* Galileo :ASSIGNMENT:
:PROPERTIES:
:BASEDIR: Galileo
:END:
** testing
#+BEGIN_SRC emacs-lisp
(let
((parent-basedir nil))
(save-excursion
(outline-up-heading)
(setq parent-basedir (org-entry-get (point) "BASEDIR"))
(message parent-basedir))
(let
((default-directory (concat default-directory parent-basedir) ))
(call-interactively 'org-attach-attach )))
#+END_SRC
This seems to work but so far I'm having issues actually opening the
attachment. This may be due to the way that org-attach constructs links to
attachments (I prefer not to copy, as my disk space is limited).
Anyway, thanks for your help; this seems to be getting closer, despite what
feels like substantial mental impairment due to increased cranial pressure
(ouch!)

don't worry and get well soon ;).

I use Emacs 25 and there outline-up-heading uses a mandatory
parameter. I changed that to (outline-up-heading 1).

I haven't used attachments before, so I'm not sure what to expect. But if
I use the code from above, I get the attachment related properties, as you
said. Next I do M-x org-attach o and I get prompted for the attachment,
which isn't right I think. The reason is IMO, that org-attach-open
searches the attachment below the default-directory, not in the changed
path. So, if the default-directory is /tmp, it searches /tmp/data/$ID,
not /tmp/Galileo/date/$ID. Thinking about it that makes sense, somehow ;).
So it looks like the are several more places where 'cheating' is needed
to make this work.

I can feel your pain. Last week I had something that could have been an
inflammation of the middle ear or something like that. For two nights it
felt like my ear and the associated part of the head will explode. One
don't need that too often ;).

Yes. Looks like I wold need to rewrite org-attach-attach and bind to my new
function; that feels hard so I've sort of given up on it for now.

sorry ofr the longdelay. If I don get around to rewriting org-attach-attach
I'll report back.
