Creating Global Variable from Installation Node

[jbm]

“Who” needs to know the value of that variable?

Is that any of your program nodes?
If so, I recommend that the program nodes themselves get the variable directly from the Installation Node.
I.e. as suggested here:

Passing Information from Installation Node to Program Node

The HelloWorld example demonstrates how to get an Installation node, and call public methods within this class. In the HelloWorldProgramNodeContribution check out this part: private HelloWorldInstallationNodeContribution getInstallation() { return api.getInstallationNode(HelloWorldInstallationNodeContribution.class); } This is put into action in this case in the isDefined() method of the program node, in this way: getInstallation().isDefined() But in short, you could just do this: api.get…

If it is the user, you could consider making a “ScriptFunction” to allow the user to read this.
