Code health

3.7out of 10At risk

This codebase scores 3.7 out of 10 for code health, which we rate at risk. It also scores maintainability 5.3 and static performance 9.8 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 314 of 1,814 files are git hotspots, and they average 2.7 — which is where the fixes pay off most.

Key features of azul

  • azul provides a reactive GUI framework for Rust, C, and C++.
  • azul uses the WebRender rendering engine for desktop interface rendering.
  • azul uses a CSS and HTML-like document object model for native desktop applications.
  • azul provides code generation for a stable public API across multiple languages.

How fschutt/azul works

Application inputs enter through platform shells as DOM and layout trees, CSS, glyph resources, and window events. The core runtime processes these inputs and builds render scenes for native desktop runtimes and a web UI or server. The layout module handles document layout, including window behavior in layout/src/window.rs. The layout/src/text3/cache.rs file manages text-related caching, while layout/src/solver3/fc.rs and layout/src/solver3/display_list.rs support layout solving and display-list generation. The dll module provides desktop integration, including platform-specific code in dll/src/desktop/shell2/macos/mod.rs. The resulting output includes interactive pixels and accessibility actions.

The codebase has 1,814 files and 84,401 symbols in 11 modules, led by Rust, C and Shell. Code health is 3.7 out of 10, rated at risk.

Getting started with azul

  1. Build the azul-doc package in release mode.
    cargo build -r -p azul-doc
  2. Generate the required public API code with azul-doc.
    ./target/release/azul-doc codegen all
  3. Set the dynamic linking path for Rust rebuilds.
    export AZ_LINK_PATH=/path/to/azul/target/release
  4. Add azul with dynamic linking and run a release build of a project.
    cargo add azul --features link_dynamic

Repowise built this map of fschutt/azul from its source and git history. It parses every symbol, draws the dependency graph, scores each file's health from complexity, duplication, coverage and churn, finds hotspots and owners in the history, and writes documentation for every module. Your coding agent reads the same index over MCP, so its answers cite real files.
