How about Python 3
===========================

py3( https://github.com/liris/websocket-client/tree/py3 ) branch is for python 3.3. Every test case is passed.
If you are using python3, please check it.

Example
============

Low Level API example::

    from websocket import create_connection
    ws = create_connection("ws://echo.websocket.org/")
    print "Sending 'Hello, World'..."
    ws.send("Hello, World")
    print "Sent"
    print "Reeiving..."
    result =  ws.recv()
    print "Received '%s'" % result
    ws.close()

If you want to customize socket options, set sockopt.

sockopt example:

    from websocket import create_connection
    ws = create_connection("ws://echo.websocket.org/".
                            sockopt=((socket.IPPROTO_TCP, socket.TCP_NODELAY),) )


JavaScript websocket-like API example::

  import websocket
  import thread
  import time

  def on_message(ws, message):
      print message

  def on_error(ws, error):
      print error

  def on_close(ws):
      print "### closed ###"

  def on_open(ws):
      def run(*args):
          for i in range(3):
              time.sleep(1)
              ws.send("Hello %d" % i)
          time.sleep(1)
          ws.close()
          print "thread terminating..."
      thread.start_new_thread(run, ())


  if __name__ == "__main__":
      websocket.enableTrace(True)
      ws = websocket.WebSocketApp("ws://echo.websocket.org/",
                                  on_message = on_message,
                                  on_error = on_error,
                                  on_close = on_close)
      ws.on_open = on_open

      ws.run_forever()


wsdump.py
============

wsdump.py is simple WebSocket test(debug) tool.

sample for echo.websocket.org::

  $ wsdump.py ws://echo.websocket.org/
  Press Ctrl+C to quit
  > Hello, WebSocket
  < Hello, WebSocket
  > How are you?
  < How are you?

Usage

  -h, --help                           show this help message and exit
WebSocketApp
  -v VERBOSE, --verbose VERBOSE    set verbose mode. If set to 1, show opcode. If set to 2, enable to trace websocket module
