romangraefs Java Config library.

I intend to mostly use this library for personal projects, so documentation might be lacking in parts. If you have questions, feel free to hit me up on Twitter. That being said:

Usage

Java:

public class ConfigurableClass1 {
    public ConfigVariable<String> someConfigProp = Config.getString("someProp"); // Define a config property

    public ConfigurableClass1() {
        Config.use(FilePropertiesProvider.create("config.properties")); // Define a config source.
    }

    public void someMethod() {
        System.out.println(someConfigProp.get()); // Load data from the config.
        someConfigProp.set("New value");
    }
}

Kotlin:

val someConfigProp = Config.get<String>("someProp")
var someOtherOption by Config.get<String>("someOtherOption")


fun main() {
    Config.use(FilePropertiesProvider.create("config.properties"))
    println(someConfigProp.get())
    println(someOtherOption)
    someOtherOption = "lul"
}

Api breakdown

The API is split up into 3 parts:

• Config variables.

These are what you interact with, for most of your code. You obtain an instance by either calling Config.get(someClazz, "propName") or you can use Config.get<SomeClass>("propName") in Kotlin. Some Common Types like String have shortcut methods like Config.getString("propName").

• Variable Transformers.

These parse / serialize a string value obtained from a config source. There are some default implementations for some types (String and Integer as of right now), but you can manually create transformers by extending TransformerConfigVariable<T>.

• Config providers.

You usually install one config provider at the very start of your main using Config.use(provider). Currently there is only one Provider, which is the FilePropertiesProvider which directly utilizes standard java properties. If you want to create your own provider, you can implement ConfigProvider

Installation

Gradle via Jitpack:

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    implementation("com.github.romangraef", "jrconfig", "v1.2")
}

The version can be either a git shortref, or a tag.

Alternatively, a uberjar/fatjar/ shadow/shadedjar can be obtained from the releases.
