Virtual Object python implementation using a W3C WoT Runtime and the WoT Scripting API

VO-WoT

This repository is based on the Web of Things Python implementation WoTPy.

Introduction

This repository is a fork of the original WoTPy repository.

VO-WoT is an experimental implementation of a W3C WoT Runtime and the W3C WoT Scripting API in Python.

Inspired by the exploratory implementations located in the Eclipse thingweb GitHub page.

Features

• Supports Python 3 with versions >= 3.8
• Fully-implemented WoT interface.
• Asynchronous I/O programming model based on coroutines.
• Multiple client and server Protocol Binding implementations.

Feature support matrix

Feature	Python 3	Implementation based on
HTTP binding	:heavy_check_mark:	tornadoweb/tornado
WebSockets binding	:heavy_check_mark:	tornadoweb/tornado
CoAP binding	:heavy_check_mark:	chrysn/aiocoap
MQTT binding	:heavy_check_mark:	Yakifo/amqtt

Installation

pip install vo-wot

Development

To install in development mode with all the test dependencies:

pip install -U -e .[tests,docs]

Some WoTPy features (e.g. CoAP binding) are not available outside of Linux. If you have Docker available in your system, and want to easily run the tests in a Linux environment (whether you're on macOS or Windows) you can use the Docker-based test script:

$ WOTPY_TESTS_MQTT_BROKER_URL=mqtt://192.168.1.141 ./pytest-docker-all.sh
...
+ docker run --rm -it -v /var/folders/zd/02pk7r3954s_t03lktjmvbdc0000gn/T/wotpy-547bed6bacf34ddc95b41eceb46553dd:/app -e WOTPY_TESTS_MQTT_BROKER_URL=mqtt://192.168.1.141 python:3.9 /bin/bash -c 'cd /app && pip install -U .[tests] && pytest -v --disable-warnings'
...
Python 3.8 :: OK
Python 3.9 :: OK
Python 3.10 :: OK
Python 3.11 :: OK

WOTPY_TESTS_MQTT_BROKER_URL defines the url of the MQTT broker. It will listen to port 1883 by default. If your broker is set up in a different way, you can provide the port in the url as well.

WOTPY_TESTS_ZENOH_ROUTER_URL defines the url of the Zenoh router. An example router url value is tcp/192.168.1.1:7447 assuming the router is bound on the interface with the IP 192.168.1.1 and listens to port 7447. Check the Zenoh router's output (zenohd command) for more info.

You can also test only for a specific Python version with the PYTHON_TAG variable and the pytest-docker.sh script like this:

$ WOTPY_TESTS_MQTT_BROKER_URL=mqtt://192.168.1.141 PYTHON_TAG=3.8 ./pytest-docker.sh

Development in VSCode with devcontainers

We have also provided a convenient devcontainer configuration to better recreate your local development environment. VSCode should detect it if you have the Remote - Containers extension installed.
