kiln-ui

Reusable, game-agnostic terminal UI widgets built on ratatui.

Extracted from the kiln project so the same widgets can drive any ratatui front-end (a game editor, a text editor, …). The crate has no game-engine dependency.

Widgets

• code_editor::CodeEditor — a hand-written, modeless, keyboard-only full-screen code editor: selection, undo/redo, word/paragraph motion, system clipboard, and syntect syntax highlighting. (Highlighting is currently hardcoded to Rhai; a pluggable syntax/theme is a planned follow-up.)
• text_field::TextField — a single-line editable field (the building block for dialog inputs).
• dialog::Dialog<Ctx> — modal text-entry and filterable-list dialogs, generic over a host context they mutate only through callbacks.
• CursorOverlay / render_overlay / dim_area — the modal-overlay scaffolding: a widget paints into a buffer and returns where the caret goes; the host places it.

Notes

• Not WASM-compatible: pulls in syntect (highlighting) and arboard (system clipboard). The ratatui core itself is WASM-friendly.
• ratatui version: pinned to 0.30.x. Consumers exchange ratatui types with these widgets, so their ratatui must unify with this crate's.
