Perspective Shared Script Session Props

[PGriffith]

Passing the session object is the only supported way. There is a gross hack you can do, but as mentioned in the thread, don't expect support or be surprised if it breaks suddenly on upgrade.

Referencing a session prop from a script library?

In theory, the InternalSession.SESSION ThreadLocal would be populated if you’re running a project script from a Perspective thread; so something like this might work: from com.inductiveautomation.perspective.gateway.session import InternalSession session = InternalSession.SESSION.get() if session is not None: system.perspective.print(session.custom.something)
