Overview

In the world of Haskell development, managing domain models can often lead to overwhelming amounts of boilerplate code and various complexities. This project seeks to streamline the process by utilizing Template Haskell to enhance how we define and interact with types within our domain models. By focusing on providing a clear and distraction-free method, users can elevate their focus on the data itself rather than getting bogged down by extraneous implementation details.

The solution introduced here leverages a specially designed YAML format called Domain Schema, which simplifies the definition of types and their relationships. This innovative approach not only resolves common issues associated with record declarations and conflicting constructor names but also eliminates unnecessary boilerplate, allowing developers to maintain and create models with more efficiency and clarity.

Features

Distraction-Free Declaration: Focus solely on defining the data and its relationships without being entangled in boilerplate code and syntax issues.
Template Haskell Integration: Seamlessly integrates with Haskell's Template Haskell, requiring no additional build tools, making it easy to incorporate into existing projects.
YAML-based Domain Schema: Utilize a YAML format specifically created for defining types, offering a straightforward and comprehensible way to represent domain models.
Automatic Instance Generation: Automatically derive required instances through an analysis of the schema, saving valuable time and reducing errors.
Custom Derivation Support: Easily extend the library with an API for creating custom derivers, providing flexibility to handle unique cases or requirements.
Simplicity in Complexity: By limiting the methods of defining types to product, sum, and enum, users can build comprehensive models without a steep learning curve.
Conflict Resolution: Effectively addresses name conflicts and provides a mechanism for disambiguating record fields, ensuring clean and maintainable code.

In summary, this project offers a robust, efficient solution to a common challenge in Haskell development, allowing for clearer and more manageable domain modeling.
