Websocket Client Library
Project description
# Dataplicity Lomond
Tranquil WebSockets for Python. [Docs](https://lomond.readthedocs.io/)
Lomond is a Websocket client which turns a websocket connection in to
an orderly stream of _events_. No threads or callbacks necessary.
## How to Use
First construct a `WebSocket` object, then iterate over it to generate
an orderly sequence of events.
## Example
The following is a silly example that connects to a websocket server
(in this case a public echo server), and sends a string of text
every 5 seconds.
```python
from lomond import WebSocket
websocket = WebSocket('wss://echo.websocket.org')
for event in websocket:
if event.name == 'poll':
websocket.send_text('Hello, World')
elif event.name == 'text':
print(event.text)
```
## Events
A successful websocket connection will result in a series of events
such as the following:
```
┌──────────────────────┐
│ Connecting │ Contacting server
└──────────────────────┘
│
▼
┌──────────────────────┐ Connected to server (but
│ Connected │ not yet sent data)
└──────────────────────┘
│
▼
┌──────────────────────┐ Negotiated Websocket
│ Ready │ handshake
└──────────────────────┘
│ ┌───────────┐
│ │ │
▼ ▼ │
┌──────────────────────┐ │ Send and receive
│ Binary / Text / Poll │──┘ application data
└──────────────────────┘
│
▼
┌──────────────────────┐ Websocket close
│ Closed │ handshake
└──────────────────────┘
│
▼
┌──────────────────────┐
│ Disconnected │ Disconnected TCP/IP
└──────────────────────┘ connection to server
```
