Indentation

The text examples allow indentation. In python, indentation affects the logical meaning of the program. However, as we have seen we can use the Node constructor to provide indentation, to show the definition structure.

Listing 63 Using Node constructor to show definition structure

from ecflow import (
    Defs,
    Suite,
    Family,
    Task,
    Edit,
    Trigger,
    Complete,
    Event,
    Meter,
    Time,
    Day,
    Date,
)

print("Creating suite definition")
home = os.path.join(os.getenv("HOME"), "course")
defs = Defs(
    Suite(
        "test",
        Edit(ECF_INCLUDE=home, ECF_HOME=home),
        Family(
            "f1",
            Edit(SLEEP=20),
            Task("t1", Meter("progress", 1, 100, 90)),
            Task("t2", Trigger("t1 == complete"), Event("a"), Event("b")),
