Hi Larry,
Take a look at: http://trac.calendarserver.org/
It's Apple's open source page which includes their iCal web server...
Maybe something can be pulled from that? Just something to think
about and see if it helps :)
Also... Not sure if you've looked at the CalDav protocol but that is
what it basically runs off of so if you haven't checked it out, you
might get some better results :)

Hi folks. I am looking for a good iCal processing library (open
source / GPL compatible). Unfortunately, everything I've been able
to find so far is half-assed, incomplete, buggy, or so horribly
designed that I'd be embarrassed to use it (or several of the
above). I was hoping someone could recommend one that actually
works. I'd prefer an OO interface as it seems a natural fit, but at
this point I'll settle for whatever works.
I am not looking for an application with UI and form integration and
stuff. I just want a working stand-alone parser. (If it can be
ripped out of something more complete, that's fine.)
My needs:
1) Given raw data (provided by a user form that I can already
handle), construct iCal VEVENT information including RRULEs and
EXRULEs.
2) Given a VCALENDAR / VEVENT object, generate the appropriate iCal
text string that I can write to a file or return to the browser with
the appropriate mime header.
3) Given a VCALENDAR / VEVENT object with RRULEs and EXRULEs in it,
be able to say "give me the start/end dates of the next X
occurrences from some date" or "give me all the start/end dates of
occurrences until date Y".
What I've found so far:
http://www.kigkonsult.se/iCalcreator/ - This is the best I've found
so far, and it's what I'm using now. It's missing requirement #3,
though, as near as I can tell. Actually if I could add that
functionality to it without too much trouble I'd probably stick with
it, but it's non-trivial functionality. It's also PHP 4 OO, but I
can deal.
http://phpicalendar.net/ - This claims to do #3, I think, but it's
integrated into a web app. The code for it is also horrific, as the
entire parser is build on include files that rely on global
variables without using any functions. The security implications of
that alone scare me to death to say nothing of side effects and
stability.
http://code.google.com/p/qcal/ - Documentation is sorely lacking, as
it is listed as "pre-alpha, real alpha to be released in January".
That post was made in December, and there's still no "real
alpha". :-) So I can't really tell if it does what I need or not.
A quick search turned up nothing in PEAR, and Zend Framework has
only a proposal from 2 years ago, not an actual library.
Any others I don't know about? This seems like an area that cries
out for a good standard library, but as of yet I haven't found one
that works. Help or pointers would be much appreciated.
