pretty sure this can be done. I export only events to an ics file that
have a start and an end date and are not in a certain category. For this
I use
(defun org-mycal-export-limit (content backend info)
"Limit the export to items that have a date, time and a range. Also
exclude certain categories."
(when (eq backend 'icalendar)
(setq org-tst-regexp "<\\([0-9]\\{4\\}-[0-9]\\{2\\}-[0-9]\\{2\\} ...
[0-9]\\{2\\}:[0-9]\\{2\\}[^\r\n>]*?\\)>")
(setq org-tstr-regexp (concat org-tst-regexp "--?-?" org-tst-regexp))
(save-excursion
; get categories
(setq mycategory (org-get-category))
; get start and end of tree
(org-back-to-heading t)
(setq mystart (point))
(org-end-of-subtree)
(setq myend (point))
(goto-char mystart)
; search for timerange
(setq myresult (re-search-forward org-tstr-regexp myend t))
; search for categories to exclude
(setq mycatp (member mycategory org-export-exclude-category))
; return text if ok, nil when not ok
(if (and myresult (not mycatp)) content nil))))
(defun org-mycal-export ()
(let ((org-export-filter-final-output-functions
'(org-mycal-export-limit)))
(org-icalendar-combine-agenda-files)))
NB org-export-exclude-category is defined somewhere else
You can look up org-export-filter-final-output-functions and other hooks
at http://orgmode.org/worg/doc.html. I overwrite that hook and have it
return the content if I like the item and skip it by returning nil if I
don't like it.
You can probably use org-entry-is-done-p or org-get-todo-state to figure
out if your entry is DONE or not and org-get-scheduled-time/
org-get-deadline-time to figure out if it's scheduled.
