plugbegin

PlugBegin is a term used in software architecture to describe the initiation phase of a plugin-based system, typically the first stage of the plugin lifecycle when the host application discovers, loads, and initializes plugins. The concept is not a formal standard but a common label used in documentation and discussions to distinguish startup-time plugin handling from later lifecycle events.

During PlugBegin, the host performs discovery (scanning plugin directories or registries), integrity checks (manifest validation, version compatibility), dependency resolution (ensuring required interfaces or other plugins are available), and instantiation (creating plugin objects engineered to a common interface). It may also perform registration of plugins with central services, configuration wiring, and security checks such as sandboxing or capability assessment. After initialization, plugins typically expose lifecycle events or hooks for activation during runtime.

Variants and terminology: Some frameworks call this phase “plugin bootstrap,” “plugin initialization,” or “loading phase.” Others implement it as an event (PlugBegin event) that can be intercepted by the host or by individual plugins for custom setup.

Considerations: Error handling strategies are critical; a failed plugin during PlugBegin should not crash the host unless critical dependencies exist. Performance can be affected by synchronous versus asynchronous loading. Versioning policies and isolation strategies influence compatibility and stability.
