The Defs, Suite, Family, and Task from form a node hierarchy: Every Suite, Family, and Task must have a name. This name must be unique between the peers.

The following example show shows different ways of adding node hierarchy(they produce identical definitions)

import ecflow

s.add_family(f)
f.add_task(t)

titleHybrid. mix and match. Uses += and +
from ecflow import *
defs = Defs(Suite('s1'))
defs.s1 += Family('f1') + Task('t1')


...

The following examples show alternative styles of adding suites, families, and tasks: They produce exactly the same suite as the firstabove.


Code Block
languagepy
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
languagepy
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
languagepy
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 third 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 familesfamilies but found " + str(len(suite)))
   for fam in suite:
      assert(len(fam)==5, " expected 5 tasks but found " + str(len(fam)))
