[Pythonmac-SIG] PyObjC and Criollo HTTP server

[Rand Dvorak]

Yep, that’s it.  Just for posterity here’s the successful proof of concept.

import objc 
from Foundation import NSLog, NSRunLoop

CRApplication = objc.lookUpClass("CRApplication")
objc.registerMetaDataForSelector(
	b'CRRouter',
	b'get:block:',
	{
	'arguments': {
		3: { 'callable': {
			'arguments': {
			0:{'type': b'^v'},
			1:{'type': b'@'},
			2:{'type': b'@'},
			3:{'type': b'@'}
			},
		'	retval': { 'type': b'v' }
			}
		   }
		}
	}
)
objc.registerMetaDataForSelector(
	b'CRRouter',
	b'add:block:',
	{
	'arguments': {
		3: { 'callable': {
			'arguments': {
			0:{'type': b'^v'},
			1:{'type': b'@'},
			2:{'type': b'@'},
			3:{'type': b'@'}
			},
		'	retval': { 'type': b'v' }
			}
		   }
		}
	}
)

global server

def helloHandler(request, response, handler):
	NSLog("%@ %@ %@", request, response, handler)
	response.send_("Hello World!")
	handler()

def completionHandler(request, response, handler):
	NSLog("Completion handler called")

if __name__ == "__main__":
	server = CRApplication.sharedApplication().delegate().server()
	NSLog("Server: %@", server)
	server.get_block_("/", helloHandler)
	server.add_block_("/", completionHandler)
	NSLog("Started...")
	listening = server.startListening()
	NSRunLoop.currentRunLoop().run()

Notice the infinite loop at the bottom which is needed because the interpreter finishes executing the file and exits.  It is needed to keep the python interpreter alive.  I need a better solution to keep the interpreter alive because this eats up too much cpu. It was just a hack to prove that is what was happening.

That means you’ll probably need to run the NSRunloop or CFRunloop.
