Literals

String literals

String literals are enclosed in double quotes or single quotes. For example "Hello $name" or ’Hello’.

String literals enclosed in double quotes are parsed and rendered.

Template example
Template	Output
#set( $str1 = 'hello' ) #set( $str2 = 'world' ) #set( $str3 = "$str1 cruel $str2" ) $str3	hello cruel world

Note:

Use double quotes only when needed (decreases performance).

String literals enclosed in single quotes are not parsed and rendered.

Template example
Template	Output
#set( $str1 = 'hello' ) #set( $str2 = 'world' ) #set( $str3 = '$str1 cruel $str2' ) $str3	$str1 cruel $str2

If the string literals are enclosed by single quotes, and you want to include single quotes in the output string, you must use two consecutive single quotes. The same applies to string literals enclosed by double quotes.

Template example
Template	Output
#set( $a = 'orange') $a #set( $b = 'Hi ''banana''') $b #set( $c = "Hi ""$a""") $c #set( $d = "Hi ""$a"" and 'apple'" ) $d	orange Hi 'banana' Hi "orange" Hi "orange" and 'apple'

Integer literals

Integer literals are specified as integers.

Template example
Template	Output
#set($myint = 10) $myint

Double floating point literals

Double floating point literals are specified as numbers with decimal representation.

Template example
Template	Output
#set($mydouble = 132.245) $mydouble	132.245

Boolean literals

Boolean literals are specified as either true or false.

Template example
Template	Output
#set($mybool = true) #if($mybool) Hello world #end	Hello world
