Literals/String: Difference between revisions

=={{header|Kotlin}}==

Kotlin supports two kinds of string literals (UTF-16 encoded):

* escaped string literals, enclosed in double-quotes, which can contain 'escaped characters'.

* raw string literals, enclosed in triple double-quotes, which ignore escaping but can contain new lines.

The language also supports character literals - a single UTF-16 character (including an escaped character) enclosed in single quotes.

Here are some examples of these :

<lang scala>// version 1.0.6

fun main(args: Array<String>) {

val cl = 'a' // character literal - can contain escaped character

val esl = "abc\ndef" // escaped string literal - can contain escaped character(s)

val rsl = """

This is a raw string literal

which does not treat escaped characters

(\t, \b, \n, \r, \', \", \\, \$ and \u)

specially and can contain new lines.

"Quotes" or doubled ""quotes"" can

be included without problem but not

tripled quotes.

"""

val msl = """

|Leading whitepace can be removed from a raw

|string literal by including

|a margin prefix ('|' is the default)

|in combination with the trimMargin function.

""". trimMargin()

println(cl)

println(esl)

println(rsl)

println(msl)

}</lang>
