# A more versatile way to define event hooks than the YAML format of `config.yaml` is through native Python scripts.
|
|
# You can define hooks as simple Python functions that use the `platypush.event.hook.hook` decorator to specify on
|
|
# which event type they should be called, and optionally on which event attribute values.
|
|
#
|
|
# Event hooks should be stored in Python files under `~/.config/platypush/scripts`. All the functions that use the
|
|
# @hook decorator will automatically be discovered and imported as event hooks into the platform at runtime.
|
|
|
|
# `run` is a utility function that runs a request by name (e.g. `light.hue.on`).

Note that in this specific case we can leverage the token-extraction feature of SpeechRecognizedEvent through
