NeluaImGui

Dear ImGui / CImGui wrapper library and some examples with NeLua language

NeluaImGui: ImGui + CImGui 1.92.4 dock (2025/11)

(Another binding: NeluaImGui2: ImGui + Dear Bindings)

Prerequisites

---

• Install MSys2/MinGW (Windows OS)

• Install NeLua

• Windows OS 10 or later

  1. Install libraries

     pacman -S mingw-w64-x86_64-{gcc,clang,glfw,pkgconf,SDL2,SDL2_image} make

• Linux: Debian13 Trixie faimilies

  1. Install libraries

     $ sudo apt install gcc clang lib{opengl-dev,gl1-mesa-dev,glfw3-dev,sdl2-dev} make

• C/C++ Compiler
  GCC / Clang

Build and run on Windows OS

---

1. Download this project.

   git clone https://github.com/dinau/neluaImGui

2. Open MSys2 console and go to one of the examples folder ,

   cd neluaImGui/examples/glfw_opengl3
   make run 

Examples

imGuiToggleDemo

---

imGuiToggleDemo.nelua

imKnobsDemo

---

imKnobsDemo.nelua

imSpinnerDemo

---

Raylib + ImGui + rlImGui

---

rlimgui_basic.nelua

• Build and run

  1. Download Raylib binary for Windows: raylib-5.5_win64_mingw-w64.zip (for Linux: raylib-5.5_linux_amd64.tar.gz) then extracts it.

  2. Rename the folder name to raylib from raylib-5.5_win64_mingw-w64 (or raylib-5.5_linux_amd64).

  3. git clone https://github.com/AuzFox/Raylib.nelua
     (git SHA-1: a91ad75074e126679adbe91ab369f4d62d1563b4)

  4. Deploy them as follows,

     .
     |-- neluaImGui
     |-- raylib
     `-- Raylib.nelua

  5. cd neluaImGui/examples/rlimgui_basic
     make run

  6. If you are on Linux,

     LD_LIBRARY_PATH=../../../raylib/lib make run
