Reactive UI Toolkit

ReactiveUIToolKit brings the React component model to Unity UI Toolkit/uGUI — all in C#, no extra runtime. Write function components with hooks, compose them in UITKX (a JSX-like markup language a Roslyn source generator compiles to C# at build time), and watch changes appear instantly with built-in hot reload in Play Mode — no domain reload, roughly 100 ms. Precompiled components All runtime and editor C# ships as readable, editable source. Three assemblies ship precompiled because Unity loads them as a Roslyn analyzer and an editor plugin: Analyzers/Ruitk.SourceGenerator.dll, Analyzers/Ruitk.Language.dll and Editor/Plugins/Ruitk.Language.Editor.dll (the UITKX markup compiler and language service). They are not obfuscated, and are not intended to be edited.
