The following example shows how suites, families and tasks are added to a Python definition file.
| Code Block |
|---|
|
import ecflow
if _name_ == "_main_":
defs = ecFlow.Defs() # create an empty definition
suite = defs.add_suite("s1"); # create a suite and add it to the defs
family = suite.add_family("f1") # create a family and add it to suite
for i in [ "a", "b", "c" ]: # create task ta,tb,tc
family.add_task( "t" + i) # create a task and add to family
defs.save_as_defs("test.def") # save defs to file "test.def" |
The following examples show alternative styles of adding suites,families and tasks: They produce exactly the same suite as the first.
| Code Block |
|---|
| from ecflow import *
defs = Defs(
Suite("s1",
Family("f1",
[ Task("t{0}".format(t)) for t in ("a", "b", "c")])))
defs.save_as_defs("test.def") |
|
| Code Block |
|---|
| from ecflow import *
defs = Defs().add(
Suite("s1").add(
Family("f1").add(
[ Task("t{}".format(t))
for t in ("a", "b", "c")])))
defs.save_as_defs("test.def") |
|
| Code Block |
|---|
| from ecflow import *
defs = Defs()
defs += Suite("s1")
defs.s1 += Family("f1")
defs.s1.f1 += [ Task("t{}".format(t))
for t in ("a", "b", "c")]
defs.save_as_defs("test.def") |
|
| Warning |
|---|
In the example above we use 'defs.s1.f1' 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. |
The following example adds 5 suites, with 5 families with 5 tasks. However care needs to be taken, to ensure that python is readable. It is recommended that you check your results
| Code Block |
|---|
from ecflow import *
defs = Defs(
[ Suite("s{0}".format(i),
[ Family("f{0}".format(i),
[ Task("t{0}".format(i)) for i in range(1,6)] )
for i in range(1,6)] )
for i in range(1,6) ] )
assert(len(defs)==5, " expected 5 suites but found " + str(len(defs)))
for suite in defs:
assert(len(suite)==5, " expected 5 familes but found " + str(len(suite)))
for fam in suite:
assert(len(fam)==5, " expected 5 tasks but found " + str(len(fam))) |
