I am writing a GH calculation program in which I use Value Lists as gates to free up the calculation flow. Since these calculations take a lot of time, I am looking for a way to return the Value Lists to the “closed” value whenever I open/close the program.
This avoids the frustration of opening the program after forgetting to close these calculation gates.
For now I am improvising a solution with MetaHopper and for this I need to generate a trigger that fires once, only when I open the program. But I haven’t found a consistent solution yet, because I am new to GH.
Speaking of that conversation, here’s using the same GHPython logic to set a list of named Value List to a given index when the Grasshopper document opens:
