Contributing¶

Contributions of any sort are more than welcome, so we hope this short introduction will help you to get started! Shortly put: we use black to format our code, isort to sort our imports, pytest to test our code, flake8 to do its checks, and doc8 for documentation checks.

See Development environment for setting up a development environment, and Adding support for new devices for some helpful tips for adding support for new devices.

Development environment ¶

This section will shortly go through how to get you started with a working development environment. We use poetry for managing the dependencies and packaging, so simply execute:

poetry install

If you were not already inside a virtual environment during the install, poetry will create one for you. You can execute commands inside this environment by using poetry run <command>, or alternatively, enter the virtual environment shell by executing poetry shell to avoid repeating poetry run.

To verify the installation, you can launch tox to run all the checks:

tox

In order to make feedback loops faster, we automate our code checks by using precommit hooks. Therefore the first step after setting up the development environment is to install them:

pre-commit install

You can always execute the checks also without doing a commit.

Code checks ¶

Instead of running all available checks during development, it is also possible to execute only the code checks by calling. This will execute the same checks that would be done automatically by precommit when you make a commit:

tox -e lint

Tests ¶

We prefer to have tests for our code, so we use pytest you can also use by executing:

pytest miio

When adding support for a new device or extending an already existing one, please do not forget to create tests for your code.

Generating documentation ¶

You can compile the documentation and open it locally in your browser:

sphinx-build docs/ generated_docs
$BROWSER generated_docs/index.html

Replace $BROWSER with your preferred browser, if the environment variable is not set.

Adding support for new devices ¶

Development checklist ¶

All device classes are derived from either miio.device.Device (for MiIO) or miio.miot_device.MiotDevice (for MiOT) (Minimal example).
All commands and their arguments should be decorated with @command decorator, which will make them accessible to miiocli (miiocli).
Status containers is derived from DeviceStatus class and all properties should have type annotations for their return values.
Creating tests (Adding tests).
Updating documentation is generally not needed as the API documentation will be generated automatically.

Minimal example ¶

Todo

Add or link to an example.

miiocli integration ¶

All user-exposed methods of the device class should be decorated with miio.click_common.command() to provide console interface. The decorated methods will be exposed as click commands for the given module. For example, the following definition:

@command(
    click.argument("string_argument", type=str),
    click.argument("int_argument", type=int, required=False)
)
def command(string_argument: str, int_argument: int):
    click.echo(f"Got {string_argument} and {int_argument}")

Produces a command miiocli example command requiring an argument that is passed to the method as string, and an optional integer argument.
