This is the monolithic repository of the SixtyFPS project.

It is a toolkit to efficiently develop fluid graphical user interfaces in different languages. The aim of the project is to be

• Lightweight: We aim to provide a runtime that fits into a few hundred kilobytes of RAM and requires little processing power.
• Straightforward: We want programmers and designers to feel productive. It should be an enjoyable experience to design and developer the user interface. We aim to provide APIS that are idiomatic and easy to use for each target language, along with excellent documentation and modern tools.
• Native: We support many platforms. From embedded devices, to desktop, including mobile and web. One should feel at home on each platform. Both the user and the developer. The appearance and look and feel should match was is expected of an application build for this platform.

SixtyFPS UI comes with a mark-up language that is specifically designed for user interfaces: It provides a powerful way to describe graphical elements, their placement and the flow of data through the different states. Here's the obligatory "Hello World":

HelloWorld := Window {
    Text {
       text: "Hello, world"
    }
}
