Defines cron-like utility for scheduled times.

Scheduled Times

CronSchedule determines its scheduled times using fields, where each field is a sorted sequence of distinct values specifying a component of time.

The times field specifies local times in schedule. It must include at least one value.

The daysOfMonth field specifies days of month in schedule. If empty, then every day is implied unless daysOfWeek is non-empty.

The months field specifies months in schedule. If empty, then every month is implied.

The daysOfWeek field specifies days of week in schedule. If empty, then every day is implied unless daysOfMonth is non-empty.

If both daysOfMonth and daysOfWeek are non-empty, then scheduled times are determined as a union of both fields.

import java.time.LocalTime.NOON
import java.time.Month.{ OCTOBER, NOVEMBER, DECEMBER }

import little.time.{ CronSchedule, TimeStringMethods }

// Create schedule
val schedule = CronSchedule(
 times       = Seq(NOON),
 daysOfMonth = Seq(1, 15),
 months      = Seq(OCTOBER, NOVEMBER, DECEMBER))

val start = "2020-10-01".toLocalDate
val end   = "2020-12-31".toLocalDate

// Iterate over scheduled times
schedule.between(start, end).foreach { time =>
 println(s"${time.toLocalDate} at ${time.toLocalTime}")
}

// Create schedule using cron-like syntax
val altSchedule = CronSchedule("0 12 1,15 10-12 *")
