A binding library of imgui for Go.

Try the example with go run github.com/nitrix/imgui-go/example@latest.

The sources for it are located here example/example.go.

You're currently limited to using the OpenGL and GLFW backends. The GLFW window must be created by this other library because the backends rely on recently added enums that not all the other popular bindings support.

This package requires CGO and a C++17-capable toolchain.

Native dependencies:

• Windows: a working Go CGO toolchain and OpenGL-capable graphics drivers.
• Linux: X11, OpenGL, and audio development headers. On Debian/Ubuntu, install libx11-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libgl-dev libasound2-dev libxxf86vm-dev.
• macOS: Xcode command line tools. The package links CoreFoundation, OpenGL, Cocoa, IOKit, and QuartzCore frameworks.

The generated API intentionally stays close to cimgui. Default arguments from C++ are explicit in Go, and overload suffixes are preserved where cimgui exposes them.

Variadic C functions keep their formatting-style API in Go, for example Text("count: %d", n). Escape literal percent signs as %%, just like imgui/cimgui.

See this repo for the bindings C library and this repo for the original C++ library.
