gpui-rhai

The Rust runtime for GPUI Rhai, a desktop UI system where editable Rhai source produces a validated declarative UiNode tree and GPUI performs native layout, rendering, input, and retained work.

[dependencies]
gpui-rhai = "0.2"

For a complete application scaffold and editable first-party components:

cargo install gpui-rhai-cli --locked
cargo new my-app && cd my-app
gpui-rhai init --profile productivity
gpui-rhai add button input form_field
gpui-rhai check

What the runtime owns

• restricted Rhai compilation, lifecycle, typed state, stores, effects, and transactional reconciliation;
• a stable UiNode boundary instead of exposing GPUI Window, Context, Div, or AnyElement to scripts;
• native input/textarea, overlays, virtual collections, Canvas, motion, CodeViewer, DiffViewer, accessibility, themes and the token environment (density, size, corners), locales, the composition audit, and Host extensions;
• optional native composable charts with typed/streaming data, Geo2D, interaction, motion, Rust extensions, and SVG/PNG export;
• FileScriptView and EmbeddedScriptView preparation for standalone or embedded GPUI windows;
• explicit resource budgets and no dependency on gpui-component.

Components, layouts, themes, the token base, the typed component stylesheet, locales, and small assets are source-owned by the application after gpui-rhai-cli copies them from the version-matched gpui-rhai-registry package. The runtime itself has no visual opinions; the official design system is specified in docs/design.
