Scala – How to read environment variables in Scala


In Java, reading environment variables is done with System.getenv().

Is there a way to do this in Scala?

Best Solution

Since Scala 2.9 you can use sys.env for the same effect:

scala> sys.env("HOME")
res0: String = /home/paradigmatic

I think is nice to use the Scala API instead of Java. There are currently several project to compile Scala to other platforms than JVM (.NET, javascript, native, etc.) Reducing the dependencies on Java API, will make your code more portable.
