Clay Lua (LuaJIT + BGFX + GLFW)

A LuaJIT renderer + UI demo for [Clay], running on BGFX and GLFW via FFI.
Includes demo pages (corner radius, long lists, text alignment, floating inventory, UI controls, etc.).

A demonstration of clay_lua_bindings

Features

• Clay UI elements and scrolling with pointer integration
• Text measurement and Rich Text parsing via font_manager and stb truetype
• BGFX rendering path (rectangle, rounded corners, borders, text, images)
• Demo pages: Home, Corner Radius, Long List, Text Alignment, Floating Inventory, UI Controls

Project Layout (selected)

• main.lua — entry point; sets up window, bgfx, Clay, loads shaders, and runs the main loop.
• window.lua — GLFW window creation + callback plumbing exposed to Lua.
• font_manager.lua — text measuring utilities for Clay.
• demo/ — demo page modules loaded dynamically by the app’s body.
• component/ — UI components (checkbox, radio, slider, scrollbar, color picker, edit, property, listview, resizable).
• clay/ — Clay C header (vendored).
• shader/ — precompiled BGFX shaders (clay.vs.bin, clay.fs.bin).

Build & Run

Requirements

• LuaJIT 2.1 (runtime + dev headers)
• BGFX shared library for your OS
• GLFW shared library

Quick start

• Linux: ./run.sh
• Windows: run.bat
  (These run luajit main.lua from the repo root.)

Linux example

Run make
