Highlights

This release brings a new feature for Scala 3 that allows users deriving Config instances using the Scala 3 derives keyword.
The syntax is enabled by adding the import zio.config.magnolia.* import in the file where the case class / sealed trait is defined:

import zio.Config
import zio.config.magnolia.*

case class Foo(key1: String, key2: Int) derives Config

Updates

  • Add type-discriminator support for scala-3 auto derivation. Note that this support already existed in scala-2 auto derivation
import zio.config._, magnolia._, typesafe._

@nameWithLabel("type")
sealed trait FooBar

case class Foo(name: String) extends FooBar
case class Bar() extends FooBar

case class MyConfig(a: FooBar, b: FooBar)

val hocon = 
 s"""
   {
     a : {
       type : Foo
       name : baz
     },

     # Bar is just name since it has no fields, and therefore no need of type descriminator 
     b : Bar
   }

 """

ConfigProvder.fromHoconString(hocon).load(deriveConfig[MyConfig])

Update

With this release, zio-config stopped considering comma separated values as list, and made it configurable.

Implementation detail

zio-config depends on ZIO's Flat even to handle indexed format with the recent changes and ZIO's Flat always consider list as comma separated. This resulted in reintroducing certain issues where values with comma were considered as list in HOCON, YML etc.

This behaviour is now made configurable within zio-config, with default behaviour as not having any such assumptions.

Updates

  • Fix issue in reading boolean values from HOCON
  • Simplify defining custom DeriveConfig instance, by adding mapAttempt into DeriveConfig in both scala2 and scala3

Example:

implicit val zonedDateTimeParse: DeriveConfig[ZonedDateTime] = DeriveConfig[String].mapAttempt(ZonedDateTime.parse)

// instead of
implicit val zonedDateTimeParse: DeriveConfig[ZonedDateTime] = DeriveConfig(deriveConfig[String].mapAttempt(ZonedDateTime.parse))
  • Update documentations

Updates

  • Support period (.) character in keys of YML and JSON/HOCON.
  • Ensure that zio-config works with the orElse combinator of ZIO's ConfigProvider. This allows zio-config's complex configurations to be part of the orElse combinator of ConfigProvider. This also fixes issues such as #1095 along with making sure that we can inject HOCON/YML config providers in ZIO.Runtime
  • Ensure that we support an empty list in YML and XML.
  • Ensure that we keep the order of values in list configurations.

Most of these changes rely on using the latest indexing support in core ZIO's ConfigProvider (2.0.10). See zio/zio#7823 and zio/zio#7891. Therefore this release uses ZIO 2.0.10
