It is sometimes useful to repeat the same task or family several times,
looping on a specific value. You can do that by defining a repeat attribute.
There are three kinds of data you can loop on:
- strings
- integers
- dates
Integers and dates are specified as a range, with an optional increment (the default is one).
Ecf Script¶
We can write a ecf script /test/f4/f5/t1.ecf to use these variables
%include <head.h>
ecflow_client --label=info "My name is %NAME%" "My value is %VALUE%" "My date is %DATE%"
sleep %SLEEP%
%include <tail.h>
Text¶
Let us modify the suite definition file again
# Definition of the suite test.
suite test
edit ECF_INCLUDE "$HOME/course"
edit ECF_HOME "$HOME/course"
family f4
edit SLEEP 2
repeat string NAME a b c d e f
family f5
repeat integer VALUE 1 10
task t1
repeat date DATE 19991230 20000105
label info ""
endfamily
endfamily
endsuite
Python¶
#!/usr/bin/env python2.7
import os
import ecflow
def create_family_f4():
f4 = ecflow.Family("f4")
f4.add_variable("SLEEP", 2)
f4.add_repeat( ecflow.RepeatString("NAME", ["a", "b", "c", "d", "e", "f" ] ) )
f5 = f4.add_family("f5")
f5.add_repeat( ecflow.RepeatInteger("VALUE", 1, 10) )
t1 = f5.add_task("t1")
t1.add_repeat( ecflow.RepeatDate("DATE", 20101230, 20110105) )
t1.add_label("info", "")
return f4
print "Creating suite definition"
defs = ecflow.Defs()
suite = defs.add_suite("test")
suite.add_variable("ECF_INCLUDE", os.getenv("HOME") + "/course")
suite.add_variable("ECF_HOME", os.getenv("HOME") + "/course")
suite.add_family( create_family_f4() )
print "Checking job creation: .ecf -> .job0"
print defs.check_job_creation()
print "Saving definition to file 'test.def'"
defs.save_as_defs("test.def")
What to do:
- Type in the changes
- Load and begin the suite
- How many times will /test/f4/f5/t1 run?
- In ecflowview, try to modify the values of a repeat
