A demonstration of embedding the NED text editor into an ImGui application. This project shows how to integrate NED's editor functionality into your own ImGui-based applications.

• Embedded NED text editor with full functionality
• ImGui-based user interface
• Tree Sitter syntax highlighting
• LSP integration support
• Terminal emulator
• Multi-cursor editing

• CMake (version 3.16 or higher)
• C++17 compatible compiler
• OpenGL
• GLFW3
• GLEW
• CURL
• FreeType

brew install clang-format cmake llvm glfw glew pkg-config curl freetype

sudo apt install cmake libglfw3-dev libglew-dev libgtk-3-dev pkg-config build-essential libcurl4-openssl-dev clang-format mesa-utils libfreetype6-dev

The dependencies are managed by the build script

Clone this repository with all submodules:

git clone --recursive https://github.com/nealmick/ImGui_Ned_Embed.git
cd ImGui_Ned_Embed

Important: This project uses submodules for both ImGui and NED. Make sure to clone the repo them recursively.

# Initialize all submodules
git submodule init

The NED submodule is configured to track the main branch. To get the latest features and bug fixes:

# Update NED submodule to latest commit on main branch
git submodule update --remote ned

Run the build script:

./build.sh

For Windows users run the automated build script using powershell:

./build-win.bat
# This may take 10-20 minutes as it requires Visual Studio
# Make sure you restart powershell when prompted

The demo launches automatically after building with build-win.bat. To run it manually:

cd build/Release
ImGuiDemo.exe

./ImGuiDemo

This project uses two main submodules:

1. ImGui (imgui/): The official ImGui library from the docking branch
2. NED (ned/): The NED text editor project with all its dependencies

The NED editor is embedded through the ned_embed library, which provides a API for integration.

You can customize the ImGui configuration by modifying the ned_imgui_config.h file in the NED submodule, or by creating your own configuration file.
