Cron4s module for PureConfig

Adds support for Cron4s's CronExpr class to PureConfig.

Add pureconfig-cron4s to your project

In addition to core PureConfig, you'll need:

libraryDependencies += "com.github.pureconfig" %% "pureconfig-cron4s" % "0.17.4"

Example

To load an CronExpr into a configuration, create a class to hold it:

import cron4s.expr.CronExpr
import com.typesafe.config.ConfigFactory.parseString
import pureconfig._
import pureconfig.generic.auto._
import pureconfig.module.cron4s._

case class MyConfig(schedule: CronExpr)

We can read a MyConfig with the following code:

val conf = parseString("""{ schedule: "10-35 2,4,6 * ? * *" }""")
// conf: com.typesafe.config.Config = Config(SimpleConfigObject({"schedule":"10-35 2,4,6 * ? * *"}))

ConfigSource.fromConfig(conf).load[MyConfig]
// res0: ConfigReader.Result[MyConfig] = Right(
//   MyConfig(CronExpr(10-35, 2,4,6, *, ?, *, *))
// )
