archtool

Create a simple task management application using Python that leverages the 'archtool' package to enforce a clean architecture and manage dependencies through dependency injection (DI). This application will allow users to add tasks, mark them as completed, and delete tasks. Here’s how you can structure and implement it:

1. **Define Interfaces**: Start by defining interfaces for the key components of your application such as TaskRepository (for managing tasks), TaskService (for business logic related to tasks), and TaskController (for handling HTTP requests).
2. **Implement Interfaces**: Implement these interfaces with concrete classes that perform the actual operations. For example, TaskRepositoryImpl could interact with a SQLite database to store tasks.
3. **Dependency Injection**: Use archtool to wire up these components so that your TaskController can receive instances of TaskService and TaskService can receive instances of TaskRepository without directly creating them. This setup ensures that your code remains loosely coupled and testable.
4. **Application Logic**: Ensure that your application can handle adding new tasks, marking tasks as completed, and deleting tasks through the defined service and repository layers.
5. **User Interface**: Provide a simple command-line interface (CLI) for interacting with the task management system. Users should be able to add tasks by providing a title and description, mark tasks as completed, and delete tasks by their IDs.
6. **Testing**: Write unit tests for each of your implemented interfaces to ensure they work as expected.
7. **Documentation**: Include comments in your code explaining how archtool is being used to enforce architectural layers and manage dependencies. Additionally, provide a brief README file that explains how to run the application and the purpose of each component.

This project not only demonstrates the practical use of archtool but also provides a useful tool for managing daily tasks.
