EverlastingUtils

EverlastingUtils is a powerful, server-side utility and API library for the Fabric modding toolchain. It provides a robust framework for common, yet complex, features that mod developers frequently need, allowing them to focus more on their mod's unique content.

Core Features

EverlastingUtils is designed to accelerate development by providing ready-to-use, high-quality systems for:

* Utilities: A type-safe, multi-file configuration system with JSONC support, live reloading, and automatic version migration. * Utilities: A server-aware scheduler that properly handles synchronous (main thread) and asynchronous tasks, preventing common concurrency issues. * Utilities: A fluent, Brigadier-based command builder with integrated permission handling. * Utilities: A simple yet powerful framework for creating interactive inventory-based GUIs, including standard and anvil types. * Utilities: A collection of helpers for things like MiniMessage color parsing and toggleable, per-mod debug logging.

System Spotlights

Configuration System (`ConfigManager`)

The `ConfigManager` is a sophisticated system designed to handle all aspects of configuration management with minimal boilerplate.

Metadata & Comments * Metadata & Comments: Uses Kotlin data classes for type-safe config access and JSONC for human-readable files with comments. * Metadata & Comments: Automatically reloads configuration files from disk when they are changed, allowing server owners to adjust settings without a restart. * Metadata & Comments: Manages a main `config.jsonc` and any number of "secondary" configs in sub-directories, perfect for organizing complex data like Pokémon or loot pools. * Metadata & Comments: When you release a new version of your mod, the `ConfigManager` compares the version number in the user's config file with your mod's current version. If they don't match, it automatically merges their existing settings into a new, updated config structure, preserving their changes. * Metadata & Comments: Programmatically add header comments, footer comments, and per-field descriptions to your config files, making them self-documenting.

Example Usage: ```kotlin // 1. Define your configuration structure data class MyConfig( override val version: String = "1.0.0", override val configId: String = "mymod", // Used for the config folder name var debugMode: Boolean = false, var welcomeMessage: String = "<green>Welcome to my server!" ) : ConfigData

// 2. Initialize the manager in your mod's entry point val configManager = ConfigManager( currentVersion = "1.0.0", // Your mod's current version defaultConfig = MyConfig(), configClass = MyConfig::class, metadata = ConfigMetadata( headerComments = listOf("Main configuration for MyMod."), sectionComments = mapOf("debugMode" to "Enables detailed console logging.") ) )

// 3. Access your config anywhere val isDebug = configManager.getCurrentConfig().debugMode ```

Task Scheduler (`SchedulerManager`)

The `SchedulerManager` provides a safe and efficient way to schedule delayed or repeating tasks, built specifically for the Minecraft server environment.

Tracked Tasks * Tracked Tasks: The scheduler is tied to the server lifecycle. It automatically shuts down when the server stops and recreates its thread pool on restart, preventing thread leaks and errors. * Tracked Tasks: Easily specify whether a task should run Tracked Tasks on the main server thread (necessary for almost all Minecraft API calls) or Tracked Tasks on a worker thread (for heavy, non-API work like database queries). * Tracked Tasks: Uses a shared, managed thread pool to prevent individual mods from creating excessive threads and bogging down the server. * Tracked Tasks: All scheduled tasks are tracked by a unique ID, allowing you to cancel them later if needed.

Example Usage: ```kotlin // In your server-side initializer (e.g., inside ServerLifecycleEvents.SERVER_STARTED) val server = ... // Get the MinecraftServer instance

// Schedule a task to run every 5 minutes on the main server thread SchedulerManager.scheduleAtFixedRate( id = "mymod-broadcast-task", // Unique ID for this task server = server, initialDelay = 0, period = 5, unit = TimeUnit.MINUTES, runAsync = false, // IMPORTANT: false runs on the main server thread task = { // This code is safe to run because runAsync is false server.playerManager.broadcast(Text.literal("It has been 5 minutes!"), false) } ) ```

Other Features

Command System (`CommandManager`)

A fluent builder for creating Brigadier commands with less boilerplate. It handles permission checks automatically, supporting both vanilla OP levels and the Fabric Permissions API.

```kotlin val commandManager = CommandManager(modId = "mymod")

commandManager.command("hello", permission = "mymod.hello") { executes { context -> context.source.sendFeedback({ Text.literal("Hello, world!") }, false) 1 // Success } subcommand("admin") { executes { context -> /* ... */ } } } // Don't forget to register it! commandManager.register() ```

GUI Framework (`CustomGui` & `AnvilGuiManager`)

Quickly create interactive GUIs for your players with callback-based logic, dynamic updates, and full MiniMessage support for titles and lore.

```kotlin // Example of a simple chest GUI CustomGui.openGuiFormatted( player = player, title = "<gradient:gold:yellow>My Awesome GUI", layout = listOf( CustomGui.createFormattedButton( ItemStack(Items.DIAMOND), "<blue>Click Me!", listOf("<gray>This is a button."), player ) ), onInteract = { context -> if (context.slotIndex == 0) { player.sendMessage(Text.literal("You clicked the button!")) CustomGui.closeGui(player) } }, onClose = { /* ... */ } ) ```
