FUR (Flexible UI Rules) is Perro's declarative UI markup system, similar to JSX or XAML. Write your interface structure in markup, and Perro handles the rendering.

What is FUR?

FUR allows you to define UI layouts using a simple markup syntax. It's designed to be familiar if you've used JSX (React) or XAML (WPF/UWP).

• Declarative - describe what you want, not how to build it
• Markup-based - write UI structure in text files
• Component-based - reuse UI elements
• Styled - control appearance with attributes

Basic Example

[UI]    [Panel bg=sea-5 padding=4]        [Text font-weight=bold text-color=white text-size=xl]            Hello Perro!        [/Text]    [/Panel][/UI]
