[Jaffe2718]

Add events for (Neo)Forge/Fabric:

NeoForge

@EventBusSubscriber(modid = "midnightlib", value = Dist.CLIENT)
public class MidnightLibNeoEvent {

    @SubscribeEvent
    public void onConfigRegistered(MidnightEvent.ConfigRegistered event) {
        // ...
    }

    @SubscribeEvent
    public void onConfigScreenOpened(MidnightEvent.ConfigScreenOpened event) {
        // ...
    }

    @SubscribeEvent
    public void onConfigScreenClosed(MidnightEvent.ConfigScreenClosed event) {
        // ...
    }

    @SubscribeEvent
    public void onSetValue(MidnightEvent.SetValue event) {
        // ...
    }

    @SubscribeEvent
    public void onWriteConfig(MidnightEvent.WriteConfig event) {
        // ...
    }
}

Fabric

public class MidnightEventTest {
    public static void registerEvents() {
        MidnightEvent.CONFIG_REGISTERED.register((modid) -> System.out.println("ConfigRegistered: " + modid));
        MidnightEvent.CONFIG_SCREEN_OPENED.register((modid, screen) -> System.out.println("ConfigScreenOpened: " + modid));
        MidnightEvent.CONFIG_SCREEN_CLOSED.register((modid) -> System.out.println("ConfigScreenClosed: " + modid));
        MidnightEvent.SET_VALUE.register((modid, fieldName, old, newValue) -> System.out.printf("SetValue[%s:%s]: %s -> %s%n", modid, fieldName, old, newValue));
        MidnightEvent.WRITE_CONFIG.register((modid) -> System.out.println("WriteConfig: " + modid));
    }
}
