Sometime it is very useful to see task specific information in ecflowview.
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
%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:

#!/usr/bin/env python2.

...

...

import os
import ecflow 
 
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("f3").add_task("t1").add_label("info","") 
print defs

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:

  1. Modify the suite definition file or python script
  2. Create the new ecf script file $HOME/course/test/f3/t1.

...

  1. ecf
  2. Replace the suite definition
  3. Watch in ecflowview
