$> python setup.py install
```

using pypi package:
```
$> pip install nyamuk
```

Example
-------

Publishing a message with Qos 1 (with MQTT v3.1.1)
```python
import sys
from nyamuk import *

def nloop(client):
client.packet_write() # flush write buffer (messages sent to MQTT server)
client.loop() # fill read buffer (enqueue received messages)
return client.pop_event() # return 1st received message (dequeued)

client = Nyamuk("test_nyamuk", server="test.mosquitto.org")
ret = client.connect(version=4)
ret = nloop(client) # ret should be EventConnack object
if not isinstance(ret, EventConnack) or ret.ret_code != 0:
print 'connection failed'; sys.exit(1)

client.publish('foo/bar', 'this is a test', qos=1)
ret = nloop(client) # ret should be EventPuback

client.disconnect()
```

Subscribing a topic
```python
import sys
from nyamuk import *

def nloop(client):
client.packet_write() # flush write buffer (messages sent to MQTT server)
client.loop() # fill read buffer (enqueue received messages)
return client.pop_event() # return 1st received message (dequeued)

client = Nyamuk("test_nyamuk", server="test.mosquitto.org")
ret = client.connect(version=4)
ret = nloop(client) # ret should be EventConnack object
if not isinstance(ret, EventConnack) or ret.ret_code != 0:
print 'connection failed'; sys.exit(1)

client.subscribe('foo/bar', qos=1)
ret = nloop(client)
if not isinstance(ret, EventSuback):
print 'SUBACK not received'; sys.exit(2)
print 'granted qos is', ret.granted_qos[0]

try:
while True:
evt = nloop(client)
if isinstance(evt, EventPublish):
print 'we received a message: {0} (topic= {1})'.format(evt.msg.payload, evt.msg.topic)

# received message is either qos 0 or 1
# in case of qos 1, we must send back PUBACK message with same packet-id
if evt.msg.qos == 1:
client.puback(evt.msg.mid)

except KeyboardInterrupt:
pass

client.disconnect()
```
