In this section we show an alternative to time-based attributes, using time triggers.
The following suite based generated variables are available for time-based triggers.
(In ecflow_ui, select a suite, then look at the variables tab)
These time-based variables on the suite, use the suites calendar. The suites calendar can be configured with the clock attribute.
Here are examples of time attributes and the corresponding trigger examples
time 23:00 # trigger :TIME == 2300 date 1.*.* # trigger :DD == 1 day monday # trigger :DOW == 1 |
The ':' means a search for the variable up the node tree.
Triggers can also use AND/OR logic and the full range of operators <,>,<=,>=

Let us modify the previous definition file for family f2.
For brevity, we have omitted the previous family f1
# Definition of the suite test suite test edit ECF_INCLUDE "$HOME/course" # replace '$HOME' with the path to your home directory edit ECF_HOME "$HOME/course" family f2 edit SLEEP 20 task t1 trigger :ECF_DATE ==20200720 and :TIME >= 1000 task t2 trigger :DOW == 4 and :TIME >= 1300 task t3 trigger :DD == 1 and :TIME >= 1200 task t4 trigger (:DOW == 1 and :TIME >= 1300) or (:DOW == 5 and :TIME >= 1000) task t5 trigger :TIME == 0002 # 2 minutes past midnight endfamily endsuite |
For brevity, we have left out family f1. In python this would be:
import os from ecflow import Defs,Suite,Family,Task,Edit,Trigger,Complete,Event,Meter,Time,Day,Date,Edit def create_family_f2(): return Family("f2", Edit(SLEEP=20), Task("t1", Trigger(":ECF_DATE ==20200720 and :TIME >= 1000")), Task("t2", Trigger(":DOW == 4 and :TIME >= 1300")), Task("t3", Trigger(":DD == 1 and :TIME >= 1200")), Task("t4", Trigger("(:DOW == 1 and :TIME >= 1300) or (:DOW == 5 and :TIME >= 1000)")), Task("t5", Trigger(":TIME == 0002"))) 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_f2() )) print(defs) print("Checking job creation: .ecf -> .job0") print(defs.check_job_creation()) print("Checking trigger expressions") errors = defs.check() assert len(errors) == 0,errors print("Saving definition to file 'test.def'") defs.save_as_defs("test.def") |
