Listeners and commands

Listeners

Any @Wired component that implements Listener is registered with the server automatically during BukkitWeft.enable. Make it a @Singleton so it is registered as a single instance, and weftkit's compile-time rule checks that each @EventHandler method is well formed.

@Wired
@Singleton
public final class JoinListener implements Listener {

    private final Greeter greeter;

    public JoinListener(Greeter greeter) {
        this.greeter = greeter;
    }

    @EventHandler
    public void onJoin(PlayerJoinEvent event) {
        event.getPlayer().sendMessage(greeter.greet(event.getPlayer().getName()));
    }
}

Commands

weftkit does not register commands for you, because command setup is specific to your plugin. Build the command object through the loader and attach it to Bukkit yourself.

@Wired
@Singleton
public final class HelloCommand implements CommandExecutor {

    private final Greeter greeter;

    public HelloCommand(Greeter greeter) {
        this.greeter = greeter;
    }

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        sender.sendMessage(greeter.greet(sender.getName()));
        return true;
    }
}

Wire it in onEnable, after enable has returned the loader.

getCommand("hello").setExecutor(loader.get(HelloCommand.class));

Then declare the command in plugin.yml.

commands:
  hello:
    description: Greet the sender
