nic☒live

nic☒live is a straight C++ port of the D-based nijilive library. It aims to mirror the original node graph and rendering behavior as closely as possible, while documenting compatibility gaps.

Live Demo

• WASM/WebGL sample: https://pub-681295a74302457bbc68d86467905d4f.r2.dev/nijikan/index.html

Goals

• Implement full compatibility with nijilive in C++ (node graph + render behavior)
• Serve as a drop-in native library for the Unity plugin (replace D-based plugin)
• Enable WASM builds for web environments
• Replace D-based development to avoid platform/library constraints (graphics backends, toolchains, etc.)

Dependencies

• CMake 3.20+
• C++20 compiler
• Boost headers (uses property_tree / qvm; header-only is sufficient)
• stb_image (bundled at core/third_party/stb_image.h)
• (WASM build) Emscripten toolchain + Node.js (Emscripten uses node as emulator) and Boost headers available to the toolchain

Build

Generic (Unix-like / cross-platform)

cd nicxlive
cmake -S . -B build
cmake --build build

Windows (MSVC + vcpkg)

See BUILD.md for a step-by-step guide (vcpkg classic, Boost headers, CMake toolchain file).

Build for WASM (Emscripten)

# Set up emsdk and PATH to emcc, then:
emcmake cmake -S . -B build-wasm -DBUILD_WASM=ON -DCMAKE_BUILD_TYPE=Release \
  -DBoost_INCLUDE_DIR=$(brew --prefix)/include
cmake --build build-wasm

BUILD_WASM=ON is only honored when using the Emscripten toolchain. If you need specific exports, uncomment and adjust the add_link_options hints in CMakeLists.txt.

Progress

See doc/compat-*.md for detailed compatibility notes and remaining gaps.
