About this codebase
Hazel is primarily an early-stage interactive application and rendering engine for Windows: it takes engine source (core platform, logging/assertions, renderer, events, scenes, and tooling layers), wires those systems into runtime update/render execution flows, and produces a working editor/viewer experience (and the educational material that grows it) as the current direction of development. It exists so that new engine capabilities—starting with fast 2D rendering and progressing toward high-fidelity 3D physically-based rendering—can be built and taught step-by-step in public while the more advanced Hazel-dev implementation is selectively integrated back into this repository for supporters.

Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.

How thecherno/hazel works
Hazel provides application entry points and Windows platform utilities under Hazel/Hazel and Hazel/src/Platform/Windows, which establish platform services for the engine. The Hazel module supplies core platform, logging, assertions, renderer, events, scenes, and tooling layers that feed runtime update and rendering flows. Hazelnut composes engine capabilities into an editor experience. Sandbox presents example application behavior through Hazel extension points. Hazel-ScriptCore provides C# vector types such as Vector2.cs, Vector3.cs, and Vector4.cs for scripted interaction. Dependencies.lua declares dependency expectations used by build scripts, while scripts supports setup and project-generation workflows.
Hazel Engine This page is a map of the thecherno/hazel repository, written primarily in C++, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 151 files and 1,544 symbols in 6 modules, led by C++, C# and Luau. Code health is 7.3 out of 10, rated good.
