Add anonymous functions as denops API and return the identifiers

import { Denops } from "../mod.ts";
import * as anonymous from "./mod.ts";

export async function main(denops: Denops): Promise<void> {
  // Add anonymous functions
  const ids = anonymous.add(
    denops,
    () => {
      // Do what ever you want.
    },
    () => {
      // Do what ever you want.
    },
    // You can add as many callbacks as you want...
  );

  // Use ids to dispatch added functions from Deno
  await denops.dispatch(denops.name, ids[0]);
  await denops.dispatch(denops.name, ids[1]);

  // Or from Vim
  await denops.cmd("call denops#notify(name, id, [])", {
    name: denops.name,
    id: ids[1],
  });
}
