How to left-justify a multiline Scala string

If you ever need to left-justify a multiline Scala string, the solution is to use the stripMargin method, as shown in this example:

def getWordFormatted(s: String): String = {
      |Word of the Day
      |Word: $s

The | character has a special meaning when used in conjunction with stripMargin, so that method results in a string like this being output:

Scala: Convert a String with newline characters to a sequence/list of strings

If you ever need a Scala method/function to convert a string with newline characters in it to a sequence of strings (Seq[String]), here you go:

def convertStringWithNewlinesToSeq(s: String): Seq[String] =

You can convert the final result to a Vector, Seq, List, ArrayBuffer, Array, etc., but I prefer Vector. The Scala REPL demonstrates how it works:

scala> convertStringWithNewlinesToSeq("")
res0: Seq[String] = Vector("")

scala> convertStringWithNewlinesToSeq("foo")
res1: Seq[String] = Vector(foo)

scala> convertStringWithNewlinesToSeq("foo\nbar\nbaz")
res2: Seq[String] = Vector(foo, bar, baz)

scala> convertStringWithNewlinesToSeq("foo\nbar\nbaz\n\n")
res3: Seq[String] = Vector(foo, bar, baz)

How to create multiline strings in Scala

This is an excerpt from the Scala Cookbook (partially modified for the internet). This is Recipe 1.2, “How to Create Multiline Strings in Scala.”


You want to create multiline strings within your Scala source code, like you can with the “heredoc” syntax of other languages.


In Scala you create multiline strings by surrounding your text with three double quotes:
