A teeworlds network protocol library, designed according to sans I/O (http://sans-io.readthedocs.io/) principles

# THIS LIBRARY IS IN EARLY DEVELOPMENT

Do not get bamboozled by the mature looking readme!
This project is not in a very usable state yet. It is in very early development!
APIs might change and many essential features are missing!

## install

```bash
pip install twnet_parser
```

## sample usage

```python
import twnet_parser.packet
packet = twnet_parser.packet.parse7(b'\x04\x0a\x00\xcf\x2e\xde\x1d\04') # 0.7 close

print(packet) # => <class: 'TwPacket'>: {'version': '0.7', 'header': <class: 'Header'>, 'messages': [<class: 'CtrlMessage'>]}
print(packet.header) # => <class: 'Header'>: {'flags': <class: 'PacketFlags7, 'size': 0, 'ack': 10, 'token': b'\xcf.\xde\x1d', 'num_chunks': 0}
print(packet.header.flags) # => <class: 'PacketFlags7'>: {'control': True, 'resend': False, 'compression': False, 'connless': False}
for msg in packet.messages:
    print(msg.message_name) # => close
```

## Non-Features (also not planned for this library)

| Feature                        | Status  | Where to find it                            |
| ------------------------------ | ------- | ------------------------------------------- |
| Networking                     | :x:     | TODO: link if someone implemented it on top |
| Protocol version detection     | :x:     | TODO: link if someone implemented it on top |

Look elsewhere for these features. Or use this library to implement them on top.
