The following suite definition is NOT a real design, it just demonstrates all the variety of way of adding time dependencies.
from ecflow import Defs,Suite,Task,Day,Date,Cron,Time,TimeSlot,TimeSeries start = TimeSlot(0, 0) finish = TimeSlot(23, 0) incr = TimeSlot(0, 30) time_series = TimeSeries(start, finish, incr, True) defs = Defs( Suite("s1", Task("date", Date(1, 0, 0), # first of every month and every year Date("2.*.*"), # second of every month and every yea Date(28,2,2026)), # 28 February 2026 Task("day", Day("monday"), Day(Days.tuesday)), Task("time", Time("+00:30"), # 30 minutes after suite has begun Time("+00:30 20:00 01:00"), # 00:30,01:30,02:30....07:30 after suite start Time(0, 59, True), # 00:59 - 59 minutes past midnight Time(TimeSlot(20, 10)), # 20:10 - 10 minutes pas eight Time(TimeSlot(20, 20), True), # +20:20 - 20 minutes and 20 hours, after suite start Time(time_series), Time(0, 10), Time("+00:40"), Time("+00:40 20:00 01:00")), Task("cron", Cron("+00:00 23:00 00:30",days_of_week=[0,1,2,3,4,5,6],days_of_month=[1,2,3,4,5,6],months=[1,2,3,4,5,6]))))
The following show alternative example that produces the same definition:
start = TimeSlot(0, 0) finish = TimeSlot(23, 0) incr = TimeSlot(0, 30) time_series = TimeSeries(start, finish, incr, True) cron = Cron() cron.set_week_days( [0,1,2,3,4,5,6] ) cron.set_days_of_month( [1,2,3,4,5,6] ) cron.set_months( [1,2,3,4,5,6] ) cron.set_time_series( "+00:00 23:00 00:30" ) defs = Defs().add( Suite("s1").add( Task("date").add( Date(1, 0, 0), Date("2.*.*"), Date(28,2,2026)), Task("day").add( Day("monday"), Day(Days.tuesday)), Task("time").add( Time("+00:30"), Time("+00:30 20:00 01:00"), Time(0, 59, True), Time(TimeSlot(20, 10)), Time(TimeSlot(20, 20), True), Time(time_series), Time(0, 10), Time("+00:40"), Time("+00:40 20:00 01:00")), Task("cron").add(cron))) | start = TimeSlot(0, 0) finish = TimeSlot(23, 0) incr = TimeSlot(0, 30) time_series = TimeSeries(start, finish, incr, True) defs = Defs() + ( Suite("s1") + Task("date") + Task("day") + Task("time") + Task("cron")) defs.s1.date += [ Date(1, 0, 0), Date("2.*.*"), Date(28,2,2026) ] defs.s1.day += [ Day("monday"), Day(Days.tuesday) ] defs.s1.time += [ Time("+00:30"), Time("+00:30 20:00 01:00"), Time(0, 59, True), Time(TimeSlot(20, 10)), Time(TimeSlot(20, 20), True), Time(time_series), Time(0, 10), Time("+00:40"), Time("+00:40 20:00 01:00") ] defs.s1.cron += Cron("+00:00 23:00 00:30", days_of_week=[0,1,2,3,4,5,6], days_of_month=[1,2,3,4,5,6], months=[1,2,3,4,5,6]) |
In the example above we use 'defs.s1.date' to reference a node by name. This is useful in small designs but will produce maintenance issues in large designs IF the node names are changed.
