Overview
Ciris is a functional programming library for loading configurations.
In particular, the following features are supported.
- Loading values from multiple sources and defining default values.
- Composing multiple configuration values into larger configurations.
- Preventing secret values from being shown, redacting sensitive errors.
- Decoding configuration values to various commonly used types.
- Accumulating errors when multiple values cannot be loaded.
Documentation is kept up-to-date, currently documenting v3.8.0 on Scala 2.13.
Getting Started
To get started with sbt, add the following line to your build.sbt file.
libraryDependencies += "is.cir" %% "ciris" % "3.8.0"
Published for Scala 2.12, 2.13 and 3.3, Scala.js 1.18 and Scala Native 0.4.
For changes between versions, please refer to the release notes.
If you are using Scala.js or Scala Native, make sure to replace %% with %%% above.
For Scala 2.12, enable partial unification by adding the following line to build.sbt.
scalacOptions += "-Ypartial-unification"

Compatibility
Backwards binary-compatibility for the library is guaranteed between minor and patch versions.
Version 3.a.b is backwards binary-compatible with 3.c.d for any a > c or a = c and b > d.
Please note binary-compatibility is not guaranteed between milestone releases.
Snapshot Releases
To use the latest snapshot release, add the following lines to your build.sbt file.
resolvers += Resolver.sonatypeRepo("snapshots")
