@heyq02/openui.mbt

MoonBit parser for OpenUI Lang, compiled to Wasm-GC.

parseProgram returns JSON whose expression nodes use the same k discriminant as @openuidev/lang-core. Loading the module instantiates the Wasm module synchronously.

import { parseProgram } from "@heyq02/openui.mbt/parser";

const program = parseProgram('root = TextContent("Hello", "large")');

materializeProgram(source, schema, rootName) returns the element tree plus errors, unresolved, orphaned, and incomplete.

createStream(schema, rootName) keeps a buffer in Wasm. Closed lines stay parsed. push and set take an optional complete flag and return the official ParseResult. An unfinished line is held back until finish or complete. dispose drops that session.

npm install @heyq02/openui.mbt @openuidev/lang-core
npx oui.mbt patch

oui.mbt patch rewrites the installed @openuidev/lang-core. createParser().parse and createStreamingParser() materialize in Wasm and return the official ParseResult shape. The Renderer stays in OpenUI. The patch matches lang-core 1.0.1. A different version, or a 1.0.1 bundle whose parser call sites have changed, makes the command exit before it writes either file.
