Introduction

Dependency Injection (DI) is a cornerstone of modern software development, enabling developers to build modular, maintainable, and testable systems. The SUP Dependency Injection (sup-di) framework is a robust tool designed to simplify the creation and management of complex object trees. By providing a templated approach to dependency injection, sup-di promotes separation of concerns without enforcing a specific interface to services or clients.

sup-di is built around the concept of an ObjectManager, which acts as the central hub for managing objects, dependencies, and functions. It supports XML-based configuration, modular design, and extensibility, making it a versatile framework for a wide range of applications.

Key features of sup-di include:

• Dependency Injection for Object Creation and Function Execution: Inject dependencies into constructors and (member) functions.

• XML-Based Configuration: Define object trees and dependencies declaratively.

• Modular Design: Extend functionality with custom components and services.

• Command-Line Application: Use sup-di-composer as the composition root.

• Error Handling and Validation: Robust mechanisms for diagnosing and resolving issues.

• Support for Shared Libraries: Dynamically load external components.
