Basic Nim bindings for the Clay layout library

Apr 25, 2025

To call nicbarker/clay from Nim, we only need to cover the basic types. The CLAY macro is optional, and you can recreate it with templates/macros if needed.

Each element is declared like this:

  OpenElement()
  ConfigureOpenElement(ClayElementDeclaration(
    id: clayId("CenterBox"),
    layout: ClayLayoutConfig(
      sizing: ClaySizing(
        width: sizingAxisFixed(100),
        height: sizingAxisFixed(40),
      ),
    ),
    backgroundColor: ClayColor(r: 255, g: 0, b: 0),
    cornerRadius: cornerRadius(5)
  ))
  CloseElement()

clay.c is simply:

#define CLAY_IMPLEMENTATION
#include "clay.h"

Get the binding module here: turbo/clay.nim

Demo:

Note that Clay doesn't do any rendering, you need to hook it into your existing renderer.
