Quick start

1. Add the Bintray repository:

repositories {
    jcenter()
}

2. Add the dependency for the module(s) that you are going to use

compile 'com.jdiazcano.cfg4k:cfg4k-core:$VERSION'

fun main(args: Array<String>) {
    val source = ClassPathConfigSource("global.properties")         // Create source
    val loader = PropertyConfigLoader(source)                       // Create loader
    val provider = ProxyConfigProvider(loader)                      // Create provider
    val databaseConfig = provider.bind<DatabaseConfig>("database")  // bind and use

    println("Name: ${databaseConfig.name()}")
    println("Url: ${databaseConfig.url()}")
    println("Port: ${databaseConfig.port()}")
}

/**
 * This interface defines a database configuration
 */
interface DatabaseConfig {
    /**
     * You can have javadocs inside your properties and this is really cool
     */
    fun url(): String
    fun port(): Int
    fun name(): String

    // if you have an unused property you know it and you can delete it
    val unused: String

    @Deprecated("You can even deprecate properties!")
    fun deprecated(): Boolean
    
    val youCanuseValuesToo: String
    val andNullables: Int?
}
