Multiline Strings

This is the second of three lessons on the Scala String data type.

Use triple-quotes to create multiline strings:

val address = """
    Alvin Alexander
    123 Main Street
    Talkeetna, AK 99676
"""

Formatting multiline strings

With stripMargin and |
Using a different character, like #

Without stripMargin:

val a = 1
val b = "two"

val c = s"""
    $a
    $b
"""

With stripMargin:

val c = s"""
    |$a
    |$b
""".stripMargin.trim

// with stripMargin('c')
val c = s"""
    #$a
    #$b
""".stripMargin('#').trim

Multiline formatted string that uses a class and class members:

case class Address(
    street1: String,
    street2: String,
    city: String,
    state: String,
    zip: String
)

val a = Address(
    "P.O. Box 123",
    "",
    "Talkeetna",
    "AK",
    "99676"
)

val formattedAddress = s"""
    |${a.street1}
    |${a.street2}
    |${a.city}, ${a.state} ${a.zip}
""".stripMargin.trim
