The **Swim System** Python implementation provides a standalone set of
frameworks for building massively real-time streaming WARP clients.
The **Swim Python Client** is a streaming API client for linking to lanes
of stateful Web Agents using the WARP protocol, enabling massively
real-time applications that continuously synchronize all shared states
with ping latency. WARP is like pub-sub without the broker,
enabling every state of a Web API to be streamed, without
interference from billions of queues.
<br>
## Installation
`pip install swimos`
## Usage
```python
# Setting the value of a value lane on a remote agent.
import time
from swimos import SwimClient
with SwimClient() as swim_client:
host_uri = 'ws://localhost:9001'
node_uri = '/unit/foo'
lane_uri = 'info'
value_downlink = swim_client.downlink_value()
value_downlink.set_host_uri('ws://localhost:9001')
value_downlink.set_node_uri('/unit/foo')
value_downlink.set_lane_uri('info')
value_downlink.open()
new_value = 'Hello from Python!'
value_downlink.set(new_value)
print('Stopping the client in 2 seconds')
time.sleep(2)
```
## Development
### Dependencies
##### Code dependencies
`pip install -r requirements.txt`
##### Development tools dependencies
`pip install -r requirements-dev.txt`
### Run unit tests
##### Basic:
1) Install async test package: `pip install aiounittest`
2) Run tests: `python -m unittest`
##### With coverage:
1) Install async test package: `pip install aiounittest`
2) Install coverage package: `pip install coverage`
3) Generate report: `coverage run --source=swimos -m unittest`
4) View report: `coverage report -m`
### Run Lint
##### Manual
1) Install lint package: `pip install flake8`
2) Run checks: `flake8`
##### Automatic (before commit)
1) Install commit hook package: `pip install pre-commit`
2) Run hook installation: `pre-commit install`
### Build package
##### Building package distribution
1) Install build package: `pip install build`
2) Run: `python -m build`
##### Releasing a new version
1) Add version tag: `git tag VERSION (e.g. 0.1.0)`
2) Push to remote: `git push origin VERSION`
