Fzni

Fzni is a fictional open-source software framework used in instructional materials to illustrate modular, plugin-based architectures. It is not an actual project but serves as a neutral example to demonstrate how decoupled components can be designed, loaded, and coordinated at runtime.

In typical descriptions, fzni defines a core runtime that exposes a minimal API for loading plugins, routing events, and managing state. Plugins implement defined interfaces and can be added or removed without recompiling the core. The design emphasizes isolation, versioning of interfaces, and robust error handling to allow safe experimentation in a teaching or testing environment.

Common characteristics include a lightweight plugin loader, an event bus for loose coupling, and a configuration layer that can be driven by scripts. Cross-language examples are used in tutorials to show how a plugin written in one language can interface with the core through a defined bridge, illustrating interoperability without committing to a real-world implementation.

Usage of fzni is primarily educational, aimed at teaching software architecture, API design, and the testing of plugin systems. It is sometimes employed as a placeholder name in code samples to avoid referencing ongoing or proprietary projects, while still conveying practical concepts in modular design.
