ekrich / sconfig

Scala cross platform configuration library supporting HOCON

Version Matrix


CI Scala.js

Configuration library written in Scala which is a direct translation of the original widely used Java library.

Scala JVM, Scala Native, and Scala.js are supported. Scala JVM is fully supported whereas the other platforms support a subset of the full API.

For motivation and background about this project see the PR to the original project. The TLDR is the library was ported to Scala to support Scala Native so scalafmt which uses HOCON configuration could be compiled into a native application.

Care has been taken to keep the API the same but changes were needed when moving from the Java API. Using Java is also possible as demonstrated by including the working Java examples.

If you are looking for the original Java API, see https://github.com/lightbend/config.


Maven Central

libraryDependencies += "org.ekrich" %% "sconfig" % "x.y.z"

To use in sbt, replace x.y.z with the version from Maven Central badge above.

For non-JVM projects use %%% but please refer to the guide below for critical Scala Native and Scala.js usage information. The TLDR is that you must add a java.time library dependency to your project. Currently, the only library available is sjavatime. Refer to the sjavatime home page for the current version.

Please refer to the original library documentation here. This is to reduce the maintenance burden of this library.

The intent is to keep the library in sync with the original but each PR needs to be be ported to maintain feature parity. The documentation could contain features that are not yet implemented in this library.
