  3. def <>(that: => ConfigSource): ConfigSource

    <> is an alias to orElse.

    <> is an alias to orElse. Try this (configSource), and if it fails, try that (configSource)

    For example:

    Given three configSources, configSource1, configSource2 and configSource3, such that configSource1 and configSource2 will only have id and configSource3 act as a global fall-back source.

    The following config tries to fetch Id from configSource1, and if fails, it tries configSource2, and if both fails it gets from configSource3. Age will be fetched only from configSource3.

    val config = (string("Id") from (configSource1 orElse configSource2) |@| int("Age"))(Person.apply, Person.unapply)
read(config from configSource3)

  7. def convertKeys(f: (ConfigSourceModule.K) => ConfigSourceModule.K): ConfigSource

    Convert the keys before it is queried from ConfigSource.

    Convert the keys before it is queried from ConfigSource.

    For example:

    Given two configSources, configSource1 and configSource2, such that configSource1 can have uppercase ID and lowercase age, and configSource2 can have lowercase ID and uppercase age.

    The following solution will not help here, as you would imagine. config.mapKeys(_.toUpperCase) from configSource1 orElse config.mapKeys(_.toLowerCase) from configSource2)

    A correct solution here would be the following, indicating the fact configSources act differently for different fields.

    val idSource = configSource1.convertKeys(_.toUpperCase) <> configSource2.convertKeys(_.toLowerCase)
val ageSource = configSource1.convertKeys(_.toLowerCase) <> configSource2.convertKeys(_.toUpperCase)

val config = (string("Id") from idSource |@| int("Age") from ageSource)(Person.apply, Person.unapply)
read(config)
