Hyprland is a dynamic tiling Wayland compositor written in modern C++. It implements a wide range of Wayland protocols (XDG shell, layer shell, screencopy, input methods, color management, etc.) and provides a full desktop environment with OpenGL rendering, blur effects, animations, and Lua-based configuration. The architecture is a monolithic compositor with modular internal components: a protocol layer, desktop state management, layout algorithms (dwindle, master, scrolling, floating, Lua custom), input handling, rendering pipeline (pass elements, blur providers, window transformers), and IPC via Unix sockets. It includes a plugin system (hyprpm) and a test harness (hyprtester) for integration testing. The codebase demonstrates high craftsmanship with reusable patterns like an event bus, signal/slot system, typed config values, damage ring, and promise-based async IPC. It is actively maintained with frequent commits and a large community.
C++ Insights is a source-to-source transformation tool built on LLVM/Clang that reveals compiler-generated code by making implicit C++ mechanisms explicit. It processes C++ source through Clang's AST, applies transformations to show template expansions, lambda desugaring, coroutine state machines, lifetime tracking, and other low-level details, outputting valid C++ that illustrates what the compiler does internally. The architecture centers on AST traversal via custom visitors and code generators, with modular components for different transformation modes (standard, Cfront-style, coroutine-specific). Key entry points include Insights.cpp (main driver) and specialized generators like CoroutinesCodeGenerator.cpp. The tool serves an educational purpose, helping developers understand C++ language semantics through visualizing compiler transformations.
This repository is a curated, structured dataset of C and C++ standard features (from C99 to C++29) with per-compiler support status across multiple toolchains (GCC, Clang, MSVC, Xcode, etc.). It includes YAML data files defining features, toolchain releases, and frontend metadata, along with a C++ validation tool that enforces schema compliance and semantic consistency (e.g., verifying that referenced tool versions exist and issue trackers are properly used). The dataset is designed to power a reference website (cppstat) and is accompanied by detailed Markdown explanations for each feature. While the primary artifact is the data itself, the validator and CI pipeline demonstrate strong data engineering practices, making the repository a reliable source for compiler feature support information.
