2019-10-15Rework to remove Alexa voiceagent dependenciesScott Murray1-3/+84
Changes include: - The previous somewhat hard-coded Alexa voiceagent configuration in the app controller definition has been replaced with a scheme that allows instead specifying voiceagent configuration via the configuration file /etc/xdg/AGL/voice-high.json, and individual per-voiceagent configuration via JSON files in the directory /etc/xdg/AGL/voiceagents. See the updated README.md for more details. - The new file reading code for the above change was facilitated by bumping the C++ standard option to 17 (from 11) to allow use of the new standard library filesystem classes. - The configured voiceagents' APIs are now loaded dynamically using the afb_api_require_api call enabled by the recently exposed platform:apis:auto-ws widget permission. The widget configuration has been updated to add the permission, and also remove the previously hard-code dependency on the "alexa-voiceagent" API. - App controller event hooks are created dynamically for the events from the configured voiceagents. This is done by calling back into the app controller API at the appropriate place during initialization, replacing the previous hard-coding of events from "alexa-voiceagent". If future use cases require dynamic removal of voiceagents, then this scheme will need to be revisited, as the app controller API currently has no provision for removing events. - The IAFBApi interdace and AFBApiImpl implementation classes have been extended with additional getApi and requireApi calls to enable the above changes in a straightforward manner.

2019-02-25Refactored VSHL into vshl-core and vshl-capabilities.Naveen Bobbili1-18/+18
vshl-core: This API is responsible for request arbitration. Verbs exposed are 1. startListening 2. cancelListening 3. subscribe 4. enumerateVoiceAgents 5. setDefaultVoiceAgent Used by applications to subscribe to dialog, connection and auth states of underlying low level voiceagent bindings. Used by applications to trigger voice recognition routine of the underlying low level voiceagent binding. vshl-capabilities: This API exposes publish and subscribe methods for all the speech framework domains/capabilities. For eg. navigation, phonecontrol etc. This API is used by apps and low level voice agent binding to subscribe and publish these capability messages whenever applicable. The code for this is agl-service-voice-high-capabilities repository. This specific commit is for vshl-core API.
