LumConfig 1.0.3

LumConfig 1.0.2

A lightweight, reflection-free JSON configuration manager for .NET that supports AOT (Ahead-of-Time) compilation. Easily manage your application's configuration with simple set/get operations and seamless serialization/deserialization.

Quick Start

// Create
LumConfigManager config = new LumConfigManager();

config.Set("findmax", "xx");
config.Set("HotKey", 46);
config.Set("Now", DateTime.Now);
config.Set("TheHotKeys", new int[] { 46, 33, 21 });
config.Set("HotKeys:Mainkey", 426); // Nested configuration
config.Save("d:\\aa.json");


// Read existed file
LumConfigManager loadedConfig = new LumConfigManager("d:\\aa.json");
Console.WriteLine(loadedConfig.GetInt("HotKeys:Mainkey"));
Console.WriteLine(loadedConfig.Get("Now"));
var hotkeys = loadedConfig.Get("TheHotKeys") as IList;
foreach (var key in hotkeys)
{
    Console.WriteLine(key);
}

The config file aa.json

{"findmax":"xx","HotKey":46,"Now":"2025/9/11 10:25:50","TheHotKeys":[46,33,21],"HotKeys":{"Mainkey":426}}

Features

• 🚀 AOT-Compatible: Designed to work with AOT compilation environments
• 🔍 Reflection-Free: No runtime reflection required for operation
• 📝 Simple API: Intuitive methods for setting and retrieving values
• 🎯 Type Support: Handles basic JSON types (int, long, double, string, bool) and arrays
• 🔧 Flexible Structure: Supports nested configurations through key path notation
• 💾 Easy Persistence: Simple save/load functionality for JSON files

Installation

Add the library to your project via NuGet (LumConfig).

API Reference

Core Methods

• Set(string key, object value): Stores a value with the specified key
• Get(string key): Retrieves a value by key (returns object)
• GetInt(string key): Retrieves an integer value by key
• Save(string path): Saves configuration to a JSON file
• LumConfigManager(string path): Constructor that loads configuration from a file

Supported Value Types

• Basic JSON types: int, long, double, string, bool
• Arrays of supported types
• Complex objects are automatically stringified
• Nested configurations using colon notation (Parent:Child)

Configuration File Format

The library generates clean JSON files with support for nested structures and arrays.

Use Cases

• Application settings management
• Game configuration systems
• AOT-compatible environments (e.g., Unity IL2CPP)
• Systems where reflection is limited or prohibited
• Lightweight configuration needs without heavy dependencies

Requirements

• .NET Standard 2.0+ or .NET Framework 4.6.1+
• No external dependencies
