Plugin Types & Entry Points

July 31, 2026 · View on GitHub

OPM discovers all OVOS plugins through Python package entry points. The PluginTypes enum in ovos_plugin_manager.utils maps plugin categories to their canonical entry point group names. A matching PluginConfigTypes enum has the .config sub-group names that plugins use to expose supported-language configuration.
