translating event sexps to org for org-caldav

translating event sexps to org for org-caldav

[Myles English]

Hello,

After the recent discussion about org-caldav I thought I would give it a
try.  Unfortunately it won't work for my main diary that uses a lot of
sexps[fn:1]

From the org-caldav github page[fn:2] :

"""However, sexp-entries are insanely flexible, and there are limits as
to what the icalendar exporter will handle. For example, this here

** Regular event
   <%%(memq (calendar-day-of-week date) '(1 3 5))>

will not be exported at all."""

However, org-agenda uses these sexps to make entries in the agenda.

Would it be possible to reuse something from org-agenda to write these
entries as org items into a file that could be uploaded using
org-caldav?  Maybe org-get-entries-from-diary?  Is there a huge problem
with this that I haven't noticed?

Obviously this would just be a one-way push rather than a sync.

Thanks,
Myles

[fn:1] I think I started using sexps just because org-mode can't do
e.g. "every Monday, *between these two dates*"

This is tricky. Agenda has a notion of time span, "ox-icalendar" hasn't.
So you would have to test if sexp matches for every day between some
arbitrary chosen dates.

"ox-icalendar.el" relies on "icalendar.el" library, bundled with Emacs,
for converting diary entries. Alas, it doesn't handle sexp entries
either.

I use `org-class' for that.
