•  package util

  This is a Scala library of programming utilities.

  This is a Scala library of programming utilities. It is not intended to comprise a systematic collection but contains some tools that may be useful for some applications.

  Some highlights are a number of probability distributions, a command-line interface, a configuration package, an RSS utility, a class to handle temporary directories, control structures, a logger trait and a timer.

•  package config

  This package provides various configuration sources under a common trait Config, which is basically an immutable map.

  This package provides various configuration sources under a common trait Config, which is basically an immutable map. The following implementations are available:

  - ArgsConfig loads key/value pairs from an array of strings: array elements that contain a separator char (defined by ArgsConfig.SeparatorChar) are considered as key/value pairs, while elements not consumed by this rule can be retrieved by the remaining array (makes it suitable to scan a command line for such key/value pairs and parsing the rest with tools like described in [U1 Command-Line Interface](#u1-command-line-interface).

  - FileConfig loads key/value pairs from a specified resource file which must conform to the java.util.Properties#load(InputStream) method; there is also a factory method where the resource is looked up under the modified package name of a specified class.

  - BundleConfig loads key/value pairs from a resource bundle (according to the java.util.ResourceBundle class) of a specified base name using a locale option; there is also a factory method where the resource bundle is looked up under the modified package name of a specified class.

  * SystemPropertiesConfig is a Config object that represents the system properties of the JVM.

  * SystemEnvironmentConfig is a Config object that represents the system environment; note that the system may not support environment variables -- in this case, this object is empty.

  Multiple Configs can be combined using the standard map ++ operators, yielding an overall Config.

  Example:

  1. import de.h2b.scala.lib.util.config._
     val argsConfig = ArgsConfig("-x key1=val1 /y key2=val2 abc".split(' '))
     val sysConfig = SystemPropertiesConfig
     val otherConfig = Config("one"->1, "two"->2, "three"->3)
     val config = argsConfig ++ sysConfig ++ otherConfig
     println(config.get("key1")) //> Some(val1)
     println(config.get("java.version")) //> Some(1.8.0_121)
     println(config.get("two")) //> Some(2)
     println(argsConfig.remaining.mkString(" ")) //> -x /y abc
