Environment variables would be the if-all-else-fails solution to such a
problem.
For example, you would run this when you want to launch the new Nuke
session:
os.setenv("PATH_TO_SAVE_NUKE_SCRIPT_TO", "/path/to/thing.nk")
nuke.scriptNew() # or subprocess.Popen([...])
Then in a menu.py somewhere:
def example():
path = os.getenv("PATH_TO_SAVE_NUKE_SCRIPT_TO")
if path is None:
return
else:
# Clear env var to prevent it passing to further child-processes
os.environ['PATH_TO_SAVE_NUKE_SCRIPT_TO'] = ''
del os.environ[PATH_TO_SAVE_NUKE_SCRIPT_TO]
# Set root name
nuke.root()['name'].setValue(path)
nuke.addOnCreate(example, nodeClass = "Root")
