Ciris Source for Hocon file format


ciris-hocon scaladex-badge travis-badge gitter-badge

ciris-hocon provides a HOCON configuration source for Ciris configuration loading library.

The implementation of this library was created by following the excellent Ciris documentation.


Add the dependency to your project build settings:

libraryDependencies += "lt.dvim.ciris-hocon" %% "ciris-hocon" % "0.2"

Or a snapshot from a snapshot repository for which you will need an additional resolver:

resolvers += Resolver.bintrayRepo("2m", "snapshots")
version scala ciris
0.1 2.12 0.12.1
0.2 2.13 0.13.0-RC1

Example usage

This library provides configuration sources as well as decoders from ConfigValue values.

import ciris._
import lt.dvim.ciris.Hocon._
import com.typesafe.config.ConfigFactory
import scala.concurrent.duration._
import java.time.Period

val config = ConfigFactory.parseString("""
    |rate {
    |  elements = 2
    |  burst-duration = 100 millis
    |  check-interval = 2 weeks

case class Rate(elements: Int, burstDuration: FiniteDuration, checkInterval: Period)

val hocon = hoconAt(config)("rate")
val rate = loadConfig(

rate.burstDuration shouldBe 100.millis
rate.checkInterval shouldBe Period.ofWeeks(2)
