envconf

envconf

Kotlin library which makes it easy to use env variables for configs

Examples

// this gets the env variable "HELLO"
val HELLO by Environment

// this gets the env variable "HELLO_COUNT" and converts it into an int
val HELLO_COUNT by getEnv { it.toInt() }

// this does the same as the one above
val COUNT by getEnv("HELLO_") { it.toInt() }

// this does the same as the one above, but it uses 1 if the variable is missing
val COUNT by getEnv("HELLO_", 1) { it.toInt() }

// this does the same as the one above, but it uses null if the variable is missing
val COUNT by getEnv("HELLO_", String::toInt).optional()

class Konfig : Config("HELLO_") {
    // this outsources the prefix to the constructor
    val COUNT by getEnv("HELLO_", 1) { it.toInt() }
}
