This came up in private tech-support, may be useful for others as well. The attached Runner.gh file loads another gh file (example provided), sets a value to a parameter named “INPUT”, runs it, harvests the data in the parameter called “OUTPUT” and then outputs that as its own data. Runner.gh (6.1 KB) AutoFile.gh (9.1 KB)

I did’nt succed in translating this script into python. So I decided to implement it into a grasshopper file that I turned into a Rhino Command named GrasshopperPlayerOnce Instead of -GrasshopperPlayer "xx.gh" I use -GrasshopperPlayerOnce "xx.gh" It works well. The file is joined GrasshopperPlayerOnce.rhp (524 KB)

Since a newer version, my python script started working. Here is a GHPython component calling another Grasshopper file. It solve one of the limits of Hops Plugin, you can execute another Grasshopper containing some external plugin. GrasshopperPlayerOnce-launcher.ghx (52.4 KB) GrasshopperPlayerOnce-runner.ghx (15.3 KB)

Thanks, your script works pretty well for me. It´s sad that the grasshopper player is not really suited for more complex tasks (e.g. it keeps running in the background). Your script is exactly what I need. Thank you Gaspard!

I can’t make this plugin to work with files that require input from user (have Get inputs in definition).
