Message Application for Neon AI

Neon Mana

Neon Mana (Messagebus Application for Neon AI) provides tools for interacting with the MessageBus.

Install the Mana utilities Python package with: pip install neon-mana-utils The mana entrypoint is available to interact with a bus via CLI. Help is available via mana --help.

Configuration

The default behavior of Mana is to connect to the default core bus (ws://0.0.0.0:8181/core). The connection can be configured for all mana commands via:

mana configure-messagebus --host "192.168.1.100" --port 18181

• --host specifies the host URL or IP address
• --port specifies the port the MessageBus is running on

Any unspecified arguments will use default values.

All configurations can be printed to the terminal with:

mana print-config

Monitoring

Mana can connect to a messagebus and log all Message objects sent on that bus.

mana tail-messagebus --format

• --format flag formats serialized messages printed to the shell

Filtering Messages by type

--include and --exclude arguments may be passed to include or exclude messages with msg_type matching specified prefixes. Global filters may be specified in: ${XDG_CONFIG_HOME}/mana/filters.yml. An example filter file is included here:

include:
  - recognizer_loop
exclude:
  - "recognizer_loop:utterance"

The spec above would log any Messages that start with recognizer_loop, except messages with type recognizer_loop:utterance.

Monitoring other MessageBusses

--host, --port, --route, and --ssl may be specified to monitor a different messagebus without changing the configured bus that is used for other commands. A common use case would be to monitor the GUI bus while interacting with the core bus.

Sending Messages

There are several commands available to interact with a connected Core.

send-message

Send an arbitrary Message over the MessageBus. The specified file should be a json or yaml serialized message. --response may optionally define a response message type to wait for and print to the terminal.

Basic Commands

These are commands supported by Mycroft and all derivative cores; they replicate some of the commands originally found in mycroft-core/bin.

listen

Send a mycroft.mic.listen Message.

stop

Send a mycroft.stop Message.

say-to

Send a recognizer_loop:utterance Message to skills for processing. This sends a minimal message that is not sufficient for testing user profiles or multi-user cores.

speak

Send a speak Message to TTS for generation and playback

Messagebus API

These commands are currently specified for neon-core only and are not supported by other cores. Work is ongoing to standardize these entrypoints across projects.

get-stt

Send a neon.get_stt Message and print the returned Message with transcriptions. This will only work under NeonCore.

get-tts

Send a neon.get_tts Message and print the returned Message with a path to generated TTS. This will only work under NeonCore.

get-response

Send a recognizer_loop:utterance Message with the appropriate context to return a klat.shout response. This will only work under NeonCore and will likely be refactored to reflect NeonCore changes.
