External Configuration Build Status

This thing will load configuration from external folder, which you need to specify with -Dprops.dir system property

Out of the box it supports:

Btw, if you don't need any of those, it will not add any odd dependencies to your project

Examples

Manual use

To make something happen you need to call ExternalConfiguration.load() prior any other application calls

  import com.thenewmotion.externalconfiguration.ExternalConfiguration

  ExternalConfiguration.load()

If default options are not enough, you can add own function of type String => Any also knows as Configurable

  val myConfConfigurable: ExternalConfiguration.Configurable = propsDirPath => {
    val myConf = propsDirPath + "/myconf.myconf"
    // use myconf
  }

  ExternalConfiguration.load(ExternalConfiguration.defaultConfigurables + myConfConfigurable)
