ImGuinZ

This project aims to simply and easily build Dear ImGui (CImGui) / ImPlot (CImPlot) examples in Zig language with less external dependencies.

• ImGui / CImGui version 1.91.6dock (2024/12)

• OS: Windows and Linux

• Frontends and Backends

  	GLFW	SDL2	SDL3
  OpenGL3 backend	v	v	v

• Features

  • Included Font Awesome Icon fonts.
    
  • Included GLFW 3.3.9 static library (for Windows)
  • Included SDL2/SDL3 libraries (for Windows)
  • Included STB libraries (only stb_image) for Load / Save images
  • Available ImPlot (CImPlot) with ImDrawIdx="unsigned int"
  • Enabled Input method (IME) flag with IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS

Prerequisites

---

• Zig version confirmed

  1. Windows: zig-windows-x86_64-0.14.0-dev.2625
  2. Linux: zig-linux-x86_64-0.14.0-dev.2625

• WindowsOS

  • Windows10 or later
  • MSys2/MinGW basic commands (make, rm, cp, strip ...)

• Linux OS (Ubuntu / Debian families)

  $ sudo apt install xorg-dev libopengl-dev libgl1-mesa-dev

  and for glfw3 and sdl2,

  $ sudo apt install libglfw3 libglfw3-dev

Build and run

---

1. Download this project.

   git clone --recurse-submodules https://github.com/dinau/imguinz

2. Go to one of the examples folder,

   cd imguinz/examples/glfw_opengl3

3. Build and Run

   make run   # or  zig build --release=fast run
