Parsing Key-Value Text

Turn key=value lines into a lookup map.

KeyValue.scala

object Main {
  def main(args: Array[String]): Unit = {
    val lookup = 
    val text = "host=local\nport=8080\nuser=ann"
    val lines = text.split("\n").toList
    var config = Map[String, String]()
    for (line <- lines) {
      val eq = line.indexOf("=")
      val k = line.substring(0, eq)
      val v = line.substring(eq + 1)
      config = config + (k -> v)
    }
    val value = config.getOrElse(lookup, "?")

    println("size=" + config.size)
    println("value=" + value)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val lookup = 
    val text = "host=local\nport=8080\nuser=ann"
    val lines = text.split("\n").toList
    var config = Map[String, String]()
    for (line <- lines) {
      val eq = line.indexOf("=")
      val k = line.substring(0, eq)
      val v = line.substring(eq + 1)
      config = config + (k -> v)
    }
    val value = config.getOrElse(lookup, "?")

    println("size=" + config.size)
    println("value=" + value)
  }
}

key-value Each `key=value` line is split at the first `=` and stored in a map. Later code looks up a value by its key with a safe default.
