[Remind-Fans] help with "garbage day"

[brian hammond]

Oh I think I get what you are doing.  Mind if I double-check the logic since I'm not fully understanding SCANFROM?
 
   # SCHEDULE TRASH DAY
   # (locate first non-omitted weekday)
   REM Mon AFTER SCANFROM [trigger(today()-2)] SATISFY 1

REM Mon AFTER - this triggers a Mon or the next possible day after consecutive omitted days. If a particular Mon was omitted, this would trigger the next day, Tues, assuming that Tues is itself not omitted.

SCANFROM [trigger(today()-2)] - start looking at each date from 2 days prior to today.  What if today() is Thu?  Mon won't be found, right?  Shouldn't that be -7?

SATISFY 1 - "do nothing" since we don't want a msg displayed for the triggered date.

   # (schedule trash day on the next non-omitted day
   REM [trigger(trigdate()+1)] AFTER MSG trash


So the AFTER is here in case the next "non-omitted day" is in fact omitted?

Thanks, Brian

Crap, I misread your problem statement.  The same sort of logic should
work, but you'll have to start by triggering on the first non-omitted
weekday:

   # SCHEDULE TRASH DAY
   # (locate first non-omitted weekday)
   REM Mon AFTER SCANFROM [trigger(today()-2)] SATISFY 1
   # (schedule trash day on the next non-omitted day
   REM [trigger(trigdate()+1)] AFTER MSG trash

   # SCHEDULE PAPER RECYCLING DAY
   # (locate first non-omitted weekday)
   REM Mon AFTER SCANFROM [trigger(today()-4)] SATISFY 1
   # (locate trash day)
   REM [trigger(trigdate()+1)] AFTER SCANFROM [trigger(today()-3)] SATISFY 1
   REM [trigger(trigdate()+1)] AFTER MSG recycle paper

   # SCHEDULE PLASTIC RECYCLING DAY
   # (locate first non-omitted weekday)
   REM Mon AFTER SCANFROM [trigger(today()-7)] SATISFY 1
   # (locate trash day)
   REM [trigger(trigdate()+1)] AFTER SCANFROM [trigger(today()-6)] SATISFY 1
   # (locate paper recycling day)
   REM [trigger(trigdate()+1)] AFTER SCANFROM [trigger(today()-5)] SATISFY 1
   REM [trigger(trigdate()+1)] AFTER MSG recycle plastic

At this point things are getting a bit cumbersome.  I'd really like to
reduce this to about four REM statements, but ran into some problems
with the way OMITs interact with SCANFROM.  Perhaps someone else has a
better suggestion.
