E-Utils

EverlastingUtils (Minecraft)

Note: If you’re seeing this as a dependency or requirement for another mod, you can simply install it and ignore this documentation.

EverlastingUtils is a utility library for Fabric mod development. It provides implementations for common features that mod developers frequently need to implement:

• Configuration management with runtime reloading
• Command registration with permission handling
• Inventory GUI framework
• Utility functions and extensions

For mod developers looking to use this library, continue reading below.

Features

Config Management

• JSONC configuration with comments support
• Automatic config migration and backup
• File watching and hot reloading
• Type-safe config handling with Kotlin data classes

data class MyConfig(
    override val version: String = "1.0.0",
    override val configId: String = "mymod"
    // Your config properties here
) : ConfigData

val configManager = ConfigManager(
    currentVersion = "1.0.0",
    defaultConfig = MyConfig(),
    configClass = MyConfig::class
)

Enhanced Command System

• Fluent command builder API
• Built-in permission handling
• Subcommand support
• Alias support

commandManager.command("mycommand", permission = "mymod.command") {
    executes { context ->
        // Command logic
        1
    }
    
    subcommand("subcommand") {
        executes { context ->
            // Subcommand logic
            1
        }
    }
}

GUI Framework

• Simple inventory GUI creation
• Custom button support
• Interactive slot handling
• Dynamic content updates

CustomGui.openGui(
    player = player,
    title = "My GUI",
    layout = listOf(/* GUI items */),
    onInteract = { context ->
        // Handle interactions
    }
)

Dependencies

• Kotlin
• Fabric API
• Fabric Language Kotlin

Installation

Add to your build.gradle.kts:

dependencies {
    modImplementation "curse.maven:e-utils-1275646:6588136"
}

Usage Examples

Config Management

// Create a config
data class MyConfig(
    override val version: String = "1.0.0",
    override val configId: String = "mymod",
    var debugMode: Boolean = false
) : ConfigData

// Initialize manager
val configManager = ConfigManager(
    currentVersion = "1.0.0",
    defaultConfig = MyConfig(),
    configClass = MyConfig::class,
    metadata = ConfigMetadata(
        headerComments = listOf("My mod configuration")
    )
)

// Access config
val currentConfig = configManager.getCurrentConfig()

Command Registration

val commandManager = CommandManager("mymod")

commandManager.command("hello", permission = "mymod.hello") {
    executes { context ->
        val source = context.source
        CommandManager.sendSuccess(source, "Hello, World!")
        1
    }
}

GUI Creation

CustomGui.openGui(
    player = player,
    title = "My GUI",
    layout = listOf(
        CustomGui.createNormalButton(
            ItemStack(Items.DIAMOND),
            "Click Me!",
            listOf("Button Description")
        )
    ),
    onInteract = { context ->
        // Handle button clicks
    }
)
