# THIS LIBRARY IS IN EARLY DEVELOPMENT
2023-03-31 08:17:44 +00:00
## 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
```
2023-03-16 09:26:36 +00:00
## sample usage
2023-03-12 21:12:07 +00:00
```python
import twnet_parser.packet
packet = twnet_parser.packet.parse7(b'\x04\x0a\x00\xcf\x2e\xde\x1d\04') # 0.7 close
2023-03-16 11:08:02 +00:00
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

Look elsewhere for these features. Or use this library to implement them on top.
This project is intentionally only covering parsing the protocol.
Not fully implemeting a state machine of the protocol.
Or a fully working client / server software.
If you want to build something with this library
you do have to understand how the protocol works
and when the client and server have to send what.
This [protocol documentation](https://chillerdragon.github.io/teeworlds-protocol/index.html)
should get you started to understand the basics.
