@dreamscript/paper

Typed Paper command and event authoring APIs for DreamScript Script Packages. Install this package with @dreamscript/server and the target-compatible @dreamscript/paper-api Binding Package.

import { definePackage } from "@dreamscript/server";
import { ServerCommandEvent } from "@dreamscript/paper-api/org/bukkit/event/server/ServerCommandEvent";
import {
  literal,
  registerCommand,
  registerEvent,
  stringArgument,
} from "@dreamscript/paper";

export default definePackage({
  enable() {
    registerCommand(
      literal("greet").then(
        stringArgument("target").executes((context) => {
          context.sender.sendMessage(`Hello ${context.arguments.target}`);
        }),
      ),
    );

    registerEvent(ServerCommandEvent, (event) => {
      if (event.getCommand() === "stop-now") {
        event.setCancelled(true);
      }
    });
  },
});

The command subset supports a root literal and one single-word string argument. Event handlers are synchronous. DreamScript owns command and event registrations and releases them with the Runtime Generation that created them.
