Sometime it is very useful to see task specific information in ecflow_ui
For this we can define a label. A label is a string that is attached to a task
and that can be updated using the child command ecflow_client –label
   

Ecf Script

We will create new family f3 with a task t1.
Create ecf script $HOME/course/test/f3/t1.ecf

 

$HOME/course/test/f3/t1.ecf
%include <head.h>
n=1
while [[ $n -le 5 ]]                  # Loop 5 times
do
   msg="The date is now $(date)"
   ecflow_client --label=info "$msg"  # Set the label
   sleep 60                           # Wait a one minute
   (( n = $n + 1 ))
done

ecflow_client --label=info "I have now finished my work."

%include <tail.h>

Text

# Definition of the suite test. Note Family f1,f2 from previous pages are omitted
suite test
 edit ECF_INCLUDE "$HOME/course"
 edit ECF_HOME    "$HOME/course"
 family f3
     task t1
         label info ""
 endfamily
endsuite

Python

The following section shows how to add a ecflow.Label in python: ( Note: families f1 and f2 are omitted for brevity)

$HOME/course/test.py
import os
from ecflow import Defs,Suite,Family,Task,Edit,Trigger,Complete,Event,Meter,Time,Day,Date,Label

def create_family_f3():
    return Family("f3",
                Task("t1",
                Label("info","")))
 
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_f3()))
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

  1. Modify the suite definition file or python script
  2. Create the new ecf script file $HOME/course/test/f3/t1.ecf
  3. Replace the suite definition
  4. Watch in ecflow_ui
