Command Decorator

This file defines the Command decorator, which is used to mark class methods as script commands in the @sodacore/core library. It attaches metadata to methods, making them accessible as commands with optional descriptions and options.

---

Features

• Command Registration: Marks methods as commands that can be executed by the script system.
• Metadata Support: Allows attaching descriptions and options to commands for better documentation and usage.
• Automatic Collection: Collects all decorated methods into a metadata array for later retrieval.

---

Usage

import Command from './decorator/command';

class MyScript {
	@Command({ description: 'Say hello' })
	hello() {
		console.log('Hello!');
	}
}

• Only methods decorated with @Command will be registered as script commands.
• Classes without any @Command-decorated methods will not be loaded as script commands.

API

Command(options?: ICommandOptions): MethodDecorator

• options: Optional metadata for the command, such as description and options.
• Returns: A method decorator that registers the method as a command.

---

How It Works

• Retrieves the existing commands metadata from the target.
• Adds the new command (with its name, function, and options) to the metadata array.
• Updates the metadata on the target with the new array of commands.

---

Notes

• Use this decorator on all methods you want to expose as commands in your script system.
• The decorator relies on the Utils.getMeta and Utils.setMeta helpers for metadata management.
