I'm looking for a library to be able to express, store and retrieve recurring appointments, like "every Monday at midnight". I saw Data.Time.Recurrence, which has a nice language, but how to store the appointments? A command like: *now <- getCurrentTime recur daily `begin` now* produces an infinite list of UTCTime.
You need to define your own serialization for its structures. If "recur" can't be serialized directly, your serialization needs to have a way to represent an invocation of "recur" instead of trying to store its result. This probably isn't provided because different people/applications have different serialization needs, and it's quite easy to roll the serialization yourself given the library as a starting point. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
