ejpcmac/typed_struct

This system is the TypedStruct library for Elixir, which provides a domain-specific language for defining structs with enhanced type safety and enforcement capabilities. It supports advanced features such as opaque types, field defaults, and a plugin system that allows users to extend struct behavior at compile time. The project also includes comprehensive tooling for static analysis, testing, and documentation generation to ensure code quality and maintainability.

TypedStruct now includes a plugin interface that allows users to inject custom code at various stages of struct definition. This new capability enables the integration of helpers for all fields or the struct as a whole, such as adding descriptions or modifying field options at compile time. Users can implement callbacks like \init/1\, \field/4\, and \after\_definition/1\ to customize how structs are generated, providing a flexible way to extend the library's functionality without modifying core code.

The project now uses Nix to manage the development environment, replacing the previous manual setup instructions. A new \.check.exs\ configuration centralizes static analysis, running the compiler, tests, formatter, and documentation generation only on the last supported Elixir version to avoid compatibility issues in CI. The Credo configuration has been significantly expanded to include more checks and support for monorepo-style directory structures, and the \.gitignore\ has been updated to exclude Nix-specific artifacts like \.direnv/\.

The core \TypedStruct\ library has been significantly refactored to support a more flexible and feature-rich domain-specific language. Users can now define structs in a dedicated submodule by passing the \module:\ option to \typedstruct\. The DSL introduces a plugin system, allowing users to register plugins via the \plugin/2\ macro to extend struct behavior. Additionally, the library now supports opaque types via the \opaque: true\ option and provides better control over field enforcement with a global \enforce: true\ option that applies to all fields by default unless overridden. The documentation has also been updated to reflect these new capabilities.

The configuration file has been updated to use the modern \import Config\ syntax instead of the deprecated \use Mix.Config\. Additionally, the conditional logic for the \mix\_test\_watch\ application has been changed to apply only in the \:test\ environment, ensuring the console is cleared before each test run, whereas it previously applied to the \:dev\ environment.

Added tests for the TypedStruct plugin system; Expanded test coverage for TypedStruct macro behavior.

TypedStruct has been updated to version 0.3.0, bringing significant dependency upgrades including Credo to 1.6.3, Dialyxir to 1.1.0, and ExDoc to 0.28.0. The project now uses ExCheck for static analysis and has refined its development tooling by moving Credo and Dialyxir to dev-only dependencies, configuring custom PLT paths for CI caching, and adding a helper to append development revision status to version numbers. Documentation generation has been enhanced with additional extras and formatters, while the package description has been updated to better reflect the library's purpose.
