looping on a specific value. You can do that by defining a repeat attribute.
You can iterate over sequences of:
- strings
- integers
- dates
A sequence of integers or dates is created by specifying the
first and last element, with an optional increment (the default is one).
An ecFlow variable, whose name corresponds to the name of the repeat,
will be generated. This can be used in scripts or trigger expressions.
Ecf Script
We will add a new task /test/f4/f5/t1.
Create new ecf script file $HOME/course/test/f4/f5/t1.ecf to use these variables.
$HOME/course/test/f4/f5/t1.ecf
%include <head.h> ecflow_client --label=info "My name is '%NAME%' " " My value is '%VALUE%' " " My date is '%DATE%' " # Note the use of repeat date generated variables DATE_YYYY, DATE_MM, DATE_DD, DATE_DOW to automatically reference year,month,day of the month,day of the week # These can also be used in trigger expression. ecflow_client --label=date "year(%DATE_YYYY%) month(%DATE_MM%) day of month(%DATE_DD%) day of week(%DATE_DOW%)" sleep %SLEEP% %include <tail.h>
Text
Let us modify the suite definition file again
# Definition of the suite test. suite test edit ECF_INCLUDE "$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 20101230 20110105 label info "" label date "" endfamily endfamily endsuite
Python
$HOME/course/test.py
import os from ecflow import Defs,Suite,Family,Task,Edit,Trigger,Complete,Event,Meter,Time,Day,Date,Label, \ RepeatString,RepeatInteger,RepeatDate def create_family_f4(): return Family("f4", Edit(SLEEP=2), RepeatString("NAME", ["a", "b", "c", "d", "e", "f" ]), Family("f5", RepeatInteger("VALUE", 1, 10), Task("t1", RepeatDate("DATE", 20101230, 20110105), Label("info",""), Label("date","")))) print("Creating suite definition") home = os.path.join(os.getenv("HOME"), "course") defs = Defs( Suite("test", Edit(ECF_INCLUDE=home, ECF_HOME=home), create_family_f4())) 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")
What to do
- Type in the changes
- Replace the suite definition
- How many times will /test/f4/f5/t1 run?
- In ecflow_ui , try to modify the values of a repeat
- Since we are using 2 second delay, remember to use f5(refresh) to see the intermediate values. The default is to refresh every 60 seconds.
