[kepler-dev] Configuration of workflow

Funny you should mention workflow configuration, because that's what
I'm working on today.
$PTII/ptolemy/data/expr/ParameterSet.java is the prototype of what
Edward and I have planned. ParameterSet extends
ScopeExtendingAttribute and reads in a file in the format of option
#2. The idea is that the user drags in a ParameterSet attribute
which reads in a file that sets parameters. There is a cool trick
to display all the parameters as well.
I'm working on a UI that will allow the user to set the file
name and edit the file directly.
Option 3 is appealing. This is a life cycle management issue
and worth looking in to.
We chose to start with option #2 because we think it will be easier
for users to understand.
I should have something concrete by Wednesday. I welcome your
feedback on the design.
BTW - I'll be away in the desert Thursday, June 29 through July 11.
We have a workflow with lots of StringParameters and the user
executes it command-line (without GUI).
I am looking for ways to conveniently use a configuration file for the
workflow. Does anyone have a workflow that takes parameters from file?
Edit the workflow's xml file, for the StringParameter properties.
Ugly and user-hately.
Have a config file with format
And create a script that replaces the parameters' values in the workflow's
xml before running it.
Modestly-ugly but efficient and physicist-user-friendly.
Create a subworkflow to read the config file and set variables within the
workflow. This subworkflow should go in front of the rest of the workflow.
Nice, user-friendly and built-in solution.
Here I face the problem, that VariableSetter actor cannot accept variable
names, only the values. Is there any solution in Ptolemy/Kepler?
Native Ptolemy/Kepler support...? E.g. an actor written in Java.
Thanks in advance for advice or more options
