Set an environment variable for Script Filter

[sigito]

Hi everyone. I have a simple workflow with a script filter. The executed script reads environment variables for the run configuration. Since the Script Filter is an input object, it ignores the variables set upstream. So what I can do is set the Workflow's global variables. However, I want to duplicate the script filter to have different configuration for different keywords, and global variables won't allow me this. IS there a way to do this per script filter?

It doesn't. You're likely doing something wrong.

The simplest solution would be to prefix the variables with the keyword, and have a different set of variables for each Script Filter.

I hope I do something wrong, but in my understanding the upstream variables are only applied if I trigger the wofrkflow with an input element before the variable element. E.g., if I put a Keyword before. But in case the variables are dangling, like on an attached screenshot, it doesn't work.

I think I would specify the desired variable values as options to the script filter, and parse them in the binary. That seems to be the easiest solution, which does not require hardcoding of the prefixes as you suggested. Thanks.

Yes. If your entry point is a Script Filter, then anything upstream of that doesn't get run.

If they don't need to be edited by the user, that's also perfectly fine.
