cimgui is a C language binding generator and wrapper library for Dear ImGui, a popular C++ immediate-mode GUI library. It provides a programmatically generated C API (cimgui.h/cpp) that exposes both public and internal ImGui functions, structs, and enums, along with backend-specific wrappers for GLFW, SDL2/3, Vulkan, OpenGL, and DirectX11. The core of the project is a Lua-based code generator (generator.lua, cpp2ffi.lua) that parses ImGui C++ headers and emits C bindings, metadata files (JSON/Lua), and backend implementations. The repository includes example applications demonstrating usage with various graphics backends and a CMake-based build system for easy integration. While not a standalone application, it serves as a foundational library for embedding Dear ImGui in C projects or for generating FFI bindings to other languages (e.g., Python, Rust, C#). The generator is designed to be extensible, supporting custom configurations and inherited types, making it suitable for binding other ImGui-based libraries like cimplot or cimnodes.
nvml-wrapper is a Rust workspace providing safe, high-level bindings to the NVIDIA Management Library (NVML). It is a library crate, not an application: there are no binaries, servers, or CLIs. The workspace is split into `nvml-wrapper-sys` (low-level FFI bindings, including runtime loading of `libnvidia-ml.so`/`nvml.dll` via `libloading`) and `nvml-wrapper` (a safe, typed API). The primary entry point is `Nvml::init()`, which loads the NVML library and returns a handle; from there, `Device` exposes 100+ methods for querying GPU state such as memory, clocks, temperature, power, ECC, NvLink, vGPU, MIG, and GPM metrics. The crate also supports mutating operations like setting application clocks and fan speed, and includes a `legacy-functions` feature for older NVML versions.
