PyTradfri 2.0: sans-io

[balloob]

In the Python community there has been a movement to make Sans-IO libraries. For an intro, see this talk by Cory Benfield at PyCon 2016.

The idea is to separate the parser from the actual sending/receiving of messages so that there can be different implementations. With aiocoap being on the horizon (#28), I want to transform the library to be able to both support a sync and async API.

The code is already organized in such a way that the migration will be fairly painless. All writing is already done via a single method: set_values. Instead of having our methods call the API directly, we will have it return a command object. We then have different APIs that we can give the command to.

The sync API would look like this:

command = light.light_control.set_dimmer(100)
api(command)

If the API wants to consume the response from the command, we can have a callback method be added to the command that can automatically be called by an implementing API.

command = light.update()
yield from api(command)
# Under the hood api calls `command.set_result(result)`

@balloob Any news on movement to Sans-IO libraries?
