alizarin-clm

Create a fully-functional mini-application using the Python package 'alizarin-clm' which serves as a Controlled List Manager extension for Alizarin. This application will be called 'CLM Buddy'. Here’s a detailed plan on how to build it:

1. **Project Setup**: Initialize a new Python project. Install the required dependencies including 'alizarin-clm'.
2. **Core Functionality**:
   - Implement functions to create, read, update, and delete controlled lists.
   - Utilize 'alizarin-clm' to manage these operations efficiently.
3. **User Interface**: Develop a simple command-line interface (CLI) for interacting with 'CLM Buddy'. Users should be able to add items to a controlled list, view all items in a list, modify existing items, and remove items from a list.
4. **Advanced Features**:
   - Integrate a feature that allows users to categorize lists and filter items based on categories.
   - Add a search functionality to quickly find items within large lists.
5. **Data Persistence**: Ensure that the data managed by 'CLM Buddy' is saved and can be restored after the application is closed. Use file-based storage for simplicity.
6. **Error Handling**: Implement robust error handling to manage invalid inputs and operational errors gracefully.
7. **Testing**: Write unit tests to verify the correctness of each function provided by 'CLM Buddy'.
8. **Documentation**: Prepare a README file explaining how to install and use 'CLM Buddy', along with examples of common tasks.

By the end of this project, you'll have a powerful yet easy-to-use tool for managing controlled lists, demonstrating the capabilities of 'alizarin-clm' in a practical context.
