evaluating-worker-manager

Usage

evaluating.worker.ts:

import { asRuntimeError, asScope, evaluate, execute, parse } from "dicexp";
import { functionScope, operatorScope } from "@dicexp/builtins";
import { startWorkerServer } from "@dicexp/evaluating-worker-manager/internal";

const scopes = {
  "standard": asScope([operatorScope, functionScope]),
};

export type Scopes = typeof scopes;

const dicexp = { parse, execute, evaluate, asRuntimeError };
startWorkerServer(dicexp, scopes);

main.ts:

import { EvaluatingWorkerManager } from "@dicexp/evaluating-worker-manager";

// 假设在用 Vite，总之 `DicexpEvaluatingWorker` 的类型是 `new () => Worker`
import DicexpEvaluatingWorker from "./evaluating.worker?worker";
import type { Scopes } from "./evaluating.worker";

let manager: EvaluatingWorkerManager<Scopes> | undefined;

async function roll() {
  // `result` 的类型是 `EvaluationResult | ["error", "worker_client", Error]`。
  // “dicexp” 包的 README 中有列举 `EvaluationResult` 需要处理的分支。
  const result = await manager!.evaluate("d100", {
    execute: { topLevelScopeName: "standard" },
  });
  console.log(result);
}

manager = new EvaluatingWorkerManager(
  () => new DicexpEvaluatingWorker(),
  (ready) => ready && roll(),
);
