diary sexp

[Raimund Kohl-Fuechsle]

Hiya,

I have a monthly meeting on the first Thu every month for the next 12
months.  Therefor I created a diary entry this way:

%%(diary-float '(11 12 1 2 3 4 5 6 7 8 9 10) 4 1) "The Easy Way
Discourses", Mannheim

Works.  No problem.

BUT:  I would like to have Emacs telling me the Discourse number ...
something like

"The Easy Way Discourses", No 3, Mannheim

Number 1 started in Nov, no. 2 will take place in Dec and so on.  How
can I do this?

cheers, ray

This reminds me of diary-anniversary. You can can specify %d which
gives you the age.  This is independent of the diary-remind below:

%%(diary-remind '(diary-anniversary 1 7 1997) '(1 2 3 4 5 6 7)) Silvana's birthday (now %d years old)

I don't think there is something for months or even monthly difference
though.  But this function could give you hints how to implement this.

This will be very messy; you need to rewrite diary-float, a fairly complicated
function.  The problem is that you need to get the particluar month for which
the diary entry applies, something acessible only deep in the internals of
diary-float.  If this is a one-time need, I'd suggest simply writing the diary
entries manually.  If this is a general need, you'll have to go digging in the
into the code for diary-float.
