How to see which ACT Extensions are loaded with Workbench Journaling

Is there a way to check if a particular extension is already loaded (in 2023 R2)?

I have tried to do a try: except catch with Extensions.LoadExtensions but that isn't working for some reason:

try:
    Extensions.LoadExtension(
        Id="04a2fd24-d76b-45c8-8553-be985906c975",
        Version="232.12",
        Format="Scripted"
    )
except Exception as exc:
    if "Unable to find extension" in str(exc):
        raise RuntimeError("CloudConnect not installed.")
    # Message when extension is already loaded
    if "An error occurred during loading the EDRMedeso CloudConnect extension" in str(exc):
        pass

I tried using different exceptions as well

System.Exception
Ansys.Core.Scripting.ScriptingException

This is the error im getting from Workbench

System.Exception: The extension EDRMedeso CloudConnect is already loaded.

I just realized I was running a script file I had recorded, without the exception catching, that had the same name, but was in a different folder...

PEBCAK, the code in my question and your answer works as intended.

Apologies for the confusion.

try:  Extensions.LoadExtension(Id=ext_id.ToLower())
except Exception as exc:
    if "Unable to find extension" in str(exc):
        print "Extension not installed."
    elif "An error occurred during loading " in str(exc):
        print "Extension is already loaded."
    else:
        print "Unknown error loading extension."

Still having the same issue as in my original post, the exception catch is not working.

Im running the journal from File -> Scripting -> Run Script File... if that makes a difference

Landon Mitchell Kanner

print statement will not work when using "Run Script File...", but the methodology is working on my end.
What do you mean, "the exception catch is not working" ?

How about this?
for Ext in ExtAPI.ExtensionManager.Extensions: print Ext.UniqueId

Is there a way to access EXTApi in WB journaling?

Mike.Thompson

@Taneli

This script works for me in WB ACT console. "Journaling" is simply python scripting in WB. Journaling is a term used because you can record actions of the UI, but more often people use "scripting". I think this implies not only recording, but also building scripts from scratch. Either way, whatever you call it, it is the same thing.

Be sure to use proper capitalization as python is case sensitive. You can directly use "ExtAPI" in WB scripting/journaling.

@Mike.Thompson

I see, I was trying to run it in "journaling console" (File -> Scripting -> Open Command Window), since that's what were are using for the current project. Sorry for mismatching the terms there.

I tied it in the WB ACT console as well and that seems to working as intended, thanks!

The ACT console has many variables pre-defined that are not initially defined in WB scripting. Here is how to define ExtAPI in WB scripting (outside of ACT):
