Philosophy

Kura is a foundation for compiling declarative UI into efficient, reactive execution graphs for real-time engines.

It targets:

• practical for real-time engines
• lightweight enough for native engines
• expressive like Typst
• composable like Haskell
• safe like Elm

Kura compiles UI descriptions into structured UI IR, and a compiler-derived reactive graph, enabling incremental invalidation and rendering at native speeds.

Kura is not

• a general-purpose systems language
• a scripting language for game engine logic
• an ECS framework
• a browser runtime

Kura is

• A purely functional UI composition language with explicit, compiler-driven reactivity

Influences

Kura borrows core ideas from:

Influence	Contribution
Elm	Predictable UI state model
Haskell	Functional composition and purity
Typst	Expressive declarative syntax
React	Declarative UI structure and diffing concepts
ImGui	Immediate, low-overhead UI interaction patterns
