Currently we have several types of repeats. In particular we have repeat date.
repeat date YMD 20090331 20121212 1 # <start> <end> <increment>
This allows loop over a set of dates using start/end and an increment in days.
Additionally this repeat can take part in a trigger, where the sub-expression can use date arithmetic:
trigger /suite/family:YMD + 1 > 20100101 # Here the sub expression ( /suite/family:YMD + 1) will use date arithmetic
However there can be occasions where we want an arbitrary list of dates. Currently the only way to implement this is with repeat enumerated.
repeat enumerated VARIABLE 20130101 20130102 20130103
However this repeat can be any list of integers or even strings, and thus the trigger exressions does NOT use date arithmetic.
This is where we have added a new repeat. datelist.
repeat datelist YMD 20130101 20130102 20130103 20200101 20190101
A repeat datelist is a list of arbitrary dates, using YYYYMMDD format. It will use the same date arithmetic as a repeat date.
