[Pythonmac-SIG] scripting over Distributed Objects

[Georg Seifert]

Hi,

I try to script me app using the JSTalk framework. My app i written in  
cocoa. I works nice with Javascript and if I use python from within my  
app with "PyRun_SimpleString" but if I use python over the DO  
connection I get problems.

What the JSTalk framework does is it establishes a connection between  
two app (or one app and a python interpreter) over Distributed Objects.

In the script I get a reference to my NSApplication delegate and can  
use all its properties and function. But if I add some objects to my  
documents it works only as long as the script runs. It is a problem  
with the proxy objects. As long as the script runs, the proxy is  
working and the pyObjC bridge routes the method calls correctly.

I resolved this with copying the object in my accessors but then the  
reference to the object in the script becomes invalid (and I need an  
extra copy)

Does anybody has an idea what to do?
Can I somehow make python to return the actual cocoa object rather  
than the proxy?

Many Thanks
Georg


excerpt of my python code:

def application(appName):
	appPath =  
NSWorkspace.sharedWorkspace().fullPathForApplication_(appName);
	
	appBundle = NSBundle.bundleWithPath_(appPath)
	bundleId  = appBundle.bundleIdentifier()
	
	[..]

	port = bundleId + ".JSTalk"
	
	conn = None
	tries = 0
	
	while ((conn is None) and (tries < 10)):
		conn = NSConnection.connectionWithRegisteredName_host_(port, None)
		tries = tries + 1;
		
		if (not conn):
			time.sleep(1)
	
	if (not conn):
		print("Could not find a JSTalk connection to " + appName)
		return None
	
	return conn.rootProxy()

glyphs = application("Glyphs") # the reference to my App delegate

node = glyphs.node() # I need the method return a new instance as I am  
not in the scope of my app and python does not know of my classes.

path.addNode_(node)
