If getValue is declared as an extension method ktlint thinks its unused

[JLLeitschuh]

Example:

import com.natpryce.konfig.PropertyGroup
import com.natpryce.konfig.getValue
import com.natpryce.konfig.stringType

interface EventConfiguration {
    val url: String

    companion object {
        private object rabbitmq : PropertyGroup() {
            val url by stringType // This is where getValue is used.
        }
}

This is how getValue is defined:

operator fun <G : PropertyGroup, T> ((PropertyLocation, String) -> T).getValue(group: G, property: KProperty<*>) =
        group.key(property.name, this)

operator fun <SCOPE, T> ((PropertyLocation, String) -> T).getValue(scope: SCOPE?, property: KProperty<*>) =
        Key(property.name, this)

Kt-lint thinks that import com.natpryce.konfig.getValue is an unused import so you have to disable the check using // ktlint-disable.

@JLLeitschuh Thank you. Fixed in 0.8.2 (Maven Central sync might take up to 25min).

While you are at it you should fix it for setValue
