Scopt v3.3.0 Release Notes

Release Date: 2016-06-12 // almost 8 years ago

  • comma-separated values

    👍 scopt 3.3.0 adds support for comma-separated values that map to Seq[A] and Map[K, V] (where A, K and V are instance of Read).

    • A Seq[File] accepts a string containing comma-separated values such as --jars foo.jar,bar.jar
    • A Map[String, String] accepts a string containing comma-separated pairs like --kwargs key1=val1,key2=val2

    Here's how they can be used:

    opt[Seq[File]]('j', "jars") valueName("<jar1>,<jar2>...") action { (x,c) =>
  c.copy(jars = x) } text("jars to include")
opt[Map[String,String]]("kwargs") valueName("k1=v1,k2=v2...") action { (x, c) =>
  c.copy(kwargs = x) } text("other arguments")
