Scala - play2 config get section

Question

I decided to try scala out with play2. I am trying to somehow get a config section out of application config. It looks like this (by section I mean whole mail part)

services: {
  rest: {
    mail: {
      uri: "xyz",
      authorization: {
        username: "xyz",
        password: "xyz"
      }
    }
  }
}

Code

import com.typesafe.config.ConfigObject
import play.api.Play.current

val config: Option[ConfigObject] = current.configuration.getObject("services.rest.mail")

This gives Some(SimpleConfigObject()) and trough there the only way I am able to actually get mail section and use it as a ConfigObject is trough

config.get.toConfig.getString("uri")

Or I can get the actual value with

config.get.get("uri").unwrapped().toString

Or for fun:

config.get.toConfig.getObject("authorization").toConfig.getString("username")

Either way it seems to me I am doing it overly complicated. Is there some easier way to get a section from config?

Answer 1

I will post this as an answer for future reference.

After another while of playing with the code I have found parseResourcesAnySyntax method which does exactly what I want and since I have my config split into multiple parts for separate environments (application.dev.conf, etc.) I can simply do

import com.typesafe.config.{Config, ConfigFactory}
import play.api.Play._

val config: Config = ConfigFactory.parseResourcesAnySyntax("application.%s.conf" format current.mode)

and then use

config.getString("uri")

// or

config.getString("authorization.username")

// or if I want to use part of it as another section

val section: Config = config.getConfig("authorization")
section.getString("username")

Of course, another viable alternative is using a wrapper as mister Stebel recommended.
