I’m using a browser inside RF for testing fonts inside the app without any need to launch another program. So far the idea is working very well. But for some reason I need to launch a http server inside the RF which seems to be impossible. Running a simple http server outside RF is very simple. I just need to run this in shell:
> cd cwd
> python -m SimpleHTTPServer 8080
I’ve realized that every python command should be terminated in the Robofont and if the command is still running the app halts and launching the HTTPServer makes the app hang. If it was possible to run the server on another thread it would be great too but when the server is launched on another thread with the following method the server terminates after the interpreter reaches the last line.
import threading import SimpleHTTPServer import SocketServer class RunHttpdServer(): """ Runs a httpd server on another thread so you can do other things while the server is running. """ def __init__(self): self.Handler = SimpleHTTPServer.SimpleHTTPRequestHandler self.port = 8000 self.address = '' while True: try: self.httpd = SocketServer.TCPServer(('', self.port), self.Handler) self.address = 'http://localhost:%s/' %self.port print 'Serving on address:\n%s' %self.address self.thread = threading.Thread(target = self.httpd.serve_forever) self.thread.daemon = True self.thread.start() except SocketServer.socket.error as exc: if exc.args != 48: raise print 'Port', self.port, 'already in use' self.port += 1 else: break def stop(self): self.httpd.shutdown() print 'Server terminated on the address:\n%s' %self.address r = RunHttpdServer()
I can use the time.sleep(10) to make the server alive but it will also make the app hang. Do you think is there anyway to launch the server within RF and making it run forever (or a limited time) without making the RF hang? For example like launching another process in the background.

As far is I understand this example, this will run forever until a traceback is raised.
This seems to work fine with an htmlView inside RoboFont.
