Get started – Python

fuaran_ui.ui is the Pythonic author surface – snake_case names, keyword arguments, and encode that serialises byte-identically to the shared corpus.

Install

pip install fuaran-ui

Author a tree

A bare str becomes a Literal; a bare number becomes a Static binding.

from fuaran_ui.ui import fuaran, encode

tree = fuaran.dashboard(
    "root",
    children=[
        fuaran.heading("title", "Channel performance"),
        fuaran.markdown("note", "**Hello** from a Fuaran tree."),
    ],
)

Encode to canonical wire JSON

wire = encode(tree)   # canonical JSON, byte-identical to every other host

The tree you just built

Rendered by this very site from the same canonical JSON, with a one-click link into the playground:

Channel performance

Hello from a Fuaran tree.

{"accessibility":{"role":"main"},"id":"root","kind":{"$type":"Box","children":[{"id":"title","kind":{"$type":"Heading","level":2,"text":"Channel performance","variant":"Standard"}},{"id":"note","kind":{"$type":"Markdown","text":"**Hello** from a Fuaran tree."}}],"layout":{"$type":"Auto"},"role":"Dashboard"}}

The Python host is headless (authoring + codec); render the wire with any conformant host – F#, TypeScript, or the playground.
On .NET? The same tree authors in F#, C#, or VB – byte-identical on the wire.
A tree carries traits and actions, not only kinds: any node may take a hint or a text direction, and a control's action may print, or copy a value the reader is looking at. See traits and actions.
See the component reference and the guide.
