The Yui library assists in designing menu screens, pause menus, HUDs, and such.
Source code: @{https://git.doublefourteen.io/lua/yui}
Examples: @{https://git.doublefourteen.io/lua/yui-examples}
Pictures: @{https://git.doublefourteen.io/lua/yui-examples/src/branch/master/pics}
The main features: grid layout, widget navigation with keyboard/joystick buttons, support for managing custom
input devices (keyboard, mouse, touch, gamepad), and an easily extensible widget collection. The user interface is
described with a declarative approach: the layout is defined once, and events are handled in the callbacks.
Integrated support for localization was achieved through the use of another library: moonspeak.
(@{https://git.doublefourteen.io/lua/moonspeak})
Most of the widget and theme rendering code are re-used from Matthias Richter's SUIT library.
