The GodotSharp.SourceGenerators repository provides a set of Roslyn source generators designed to enhance the Godot Engine C# development experience. These generators inspect C# source code for specific attributes (such as `[SceneTree]`, `[AnimNames]`, `[AudioBus]`, etc.) and generate corresponding strongly-typed accessor code, eliminating the need for magic strings and improving compile-time safety. The project supports both Godot 3 and Godot 4 versions, with a clear migration path outlined in the documentation. The architecture follows a modular pattern where each feature (e.g., scene tree access, animation names) is implemented as a separate extension. Each extension consists of an attribute, a data model, a scraper to extract information from the project and source files, a source generator that uses Scriban templates to produce C# code, and the template itself. Shared utilities handle common tasks such as path resolution, string manipulation, and unique ID generation, promoting code reuse and consistency across generators. The repository includes extensive test suites for both Godot 3 and 4, validating the generated code against various scenarios including inheritance, same-name handling, nullable reference types, and edge cases. This ensures the generators remain robust despite Godot's evolving API. The project is actively maintained, with recent commits and a structured approach to handling breaking changes between versions.
WinFormsComInterop is a .NET library that provides a custom ComWrappers implementation for Windows Forms (and WebView2) to enable NativeAOT compilation and trimming. It includes a source generator that automatically produces Runtime Callable Wrappers (RCW) and COM Callable Wrappers (CCW) for arbitrary COM interfaces, reducing manual interop code. The repository also contains facade assemblies that stub out dependencies on System.Windows.Forms, WindowsBase, PresentationCore, and Microsoft.Web.WebView2.Core, allowing AOT-friendly builds without full desktop framework references. Multiple sample applications demonstrate usage with WinForms, Blazor Hybrid, hosted WinForms in native DLLs, and trimming. The project is actively maintained and targets .NET 6 through .NET 10, but relies on pre-release SDK versions and has some experimental components (WPF, WinUI) that are not production-ready.
