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.

Code Block
languagepy
titleUsing Node constructor to show definition structure
#!/usr/bin/env python2.7
import os
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")),
                Task("t3", Trigger("t2:a")),
                Task("t4", Trigger("t2 == complete"), Complete("t2:b")),
                Task("t5", Trigger("t1:progress ge 30")),
                Task("t6", Trigger("t1:progress ge 60")),
                Task("t7", Trigger("t1:progress ge 90"))),
            Family("f2",
                Edit(SLEEP=20),
                Task("t1", Time( "00:30 23:30 00:30" )),
                Task("t2", Day( "sunday" )),
                Task("t3", Date("1.*.*"), Time("12:00")),
                Task("t4", Time("+00:02")),
                Task("t5", Time("00:02")))))
print(defs) 

print("Checking job creation: .ecf -> .job0")  
print(defs.check_job_creation())

print("Checking trigger expressions")
assert len(defs.check()) == 0, defs.check()

print("Saving definition to file 'test.def'")
defs.save_as_defs("test.def")


We can also use python with statement to provide the indentation.

Here is the previous example using the with statement:

#!/usr/bin/env python2.7
from ecflow import Defs,Suite,Family,Task,Edit,Trigger,Complete,Event,Meter,Time,Day,Date
import os
import sys

version = sys.version_info 
if version[1] < 7: 
    print "This example requires python version 2.7, but found : " + str(version)
    exit(0)

print "Creating suite definition"  
with Defs() as defs: 
    
    with defs.add_suite("test") as suite:
        
        suite += Edit(ECF_HOME=os.path.join(os.getenv("HOME"),  "course"))
        suite += Edit(ECF_INCLUDE =os.path.join(os.getenv("HOME"),  "course"))
        
    with suite.add_family("f1") as f1:
        f1 += Edit(SLEEP=20)
        f1 += Task("t1", Meter("progress", 1, 100, 90))
        f1 += Task("t2", Trigger("t1 == complete"), Event("a"), Event("b"))
        f1 += Task("t3", Trigger("t2:a"))
        f1 += Task("t4", Trigger("t2 == complete"), Complete("t2:b"))
        f1 += Task("t5", Trigger("t1:progress ge 30"))
        f1 += Task("t6", Trigger("t1:progress ge 60"))
        f1 += Task("t7", Trigger("t1:progress ge 90"))
    
    with suite.add_family("f2") as f2:        
        f2 += Edit(SLEEP=20)
        f2 += Task("t1", Time("00:30 23:30 00:30"))
        f2 += Task("t2", Day("sunday"))
        f2 += Task("t3", Date(1, 0, 0), Time(12, 0))
        f2 += Task("t4", Time(0, 2, True))
        f2 += Task("t5", Time(0, 2))
            
print(defs)

print("Checking job creation: .ecf -> .job0")
print(defs.check_job_creation())

print("Checking trigger expressions")
print(defs.check())

print("Saving definition to file 'test.def'")
defs.save_as_defs("test.def")

Alternative styles:

languagepy
#!/usr/bin/env python2.7
