How to read environment variables in Scala

Question

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

Is there a way to do this in Scala?

Answer 1

Using directly a default with getOrElse over the sys.env Map (val myenv: Map[String, String] = sys.env):

sys.env.getOrElse(envVariable, defaultValue)

You get the content of the envVariable or, if it does not exist, the defaultValue.
