Adding Repeats

from ecflow import (
   Defs,
   Suite,
   Family,
   Task,
   RepeatDay,
   RepeatEnumerated,
   RepeatString,
   RepeatInteger,
   RepeatDateList,
)

def add_tasks(fam):
   for i in range(1, 3):
      fam.add_task(Task("t{}".format(i)))

defs = Defs()
s1 = defs.add_suite("s1")
f1 = s1.add_family("f1")
f1.add_repeat(RepeatDate("YMD", 20100111, 20100115, 2))
add_tasks(f1)

f2 = s1.add_family("f2")
f2.add_repeat(RepeatInteger("count", 0, 100, 2))
add_tasks(f2)

f3 = s1.add_family("f3")
f3.add_repeat(RepeatEnumerated("enum", ["red", "green", "blue"]))
add_tasks(f3)

f4 = s1.add_family("f4")
f4.add_repeat(RepeatString("enum", ["a", "b", "c"]))
add_tasks(f4)

f5 = s1.add_family("f5")
f5.add_repeat(RepeatDay(1))
add_tasks(f5)

f6 = s1.add_family("f6")
f6.add_repeat(
   RepeatDateList("YMD", [20130101, 20130102, 20130103])
)  # arbitrary date list
add_tasks(f6)

The following examples show alternative styles that produces the same definition:

defs = Defs(
   Suite(
      "s1",
      Family(
            "f1",
            RepeatDate("YMD", 20100111, 20100115, 2),
            [Task("t{}".format(i)) for i in range(1, 3)],
      ),
      Family(
            "f2",
            RepeatInteger("count", 0, 100, 2),
            [Task("t{}".format(i)) for i in range(1, 3)],
      ),
      Family(
            "f3",
            RepeatEnumerated("enum", ["red", "green", "blue"]),
            [Task("t{}".format(i)) for i in range(1, 3)],
      ),
      Family(
            "f4",
            RepeatString("enum", ["a", "b", "c"]),
            [Task("t{}".format(i)) for i in range(1, 3)],
      ),
      Family("f5", RepeatDay(1), [Task("t{}".format(i)) for i in range(1, 3)]),
      Family(
            "f6",
            RepeatDateList("YMD", [20130101, 20130102, 20130103]),
            [Task("t{}".format(i)) for i in range(1, 3)],
      ),
   )
)

defs = Defs() + Suite("s1")
defs.s1 += [
   Family("f{}".format(i)).add([Task("t{}".format(i)) for i in range(1, 3)])
   for i in range(1, 6)
]
defs.s1.f1 += RepeatDate("YMD", 20100111, 20100115, 2)
defs.s1.f2 += RepeatInteger("count", 0, 100, 2)
defs.s1.f3 += RepeatEnumerated("enum", ["red", "green", "blue"])
defs.s1.f4 += RepeatString("enum", ["a", "b", "c"])
defs.s1.f5 += RepeatDay(1)
defs.s1.f6 += RepeatDateList("YMD", [20130101, 20130102, 20130103])

Warning

In the second example above we use ‘defs.s1.*’ 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.
