String literal


string is zero or more characters written inside single or double quotes.

You can use quotes inside a string, as long as they don't match the quotes surrounding the string:

var
{
    var1 = "It's alright"
    var2 = "He is called 'Johnny'"
    var3 = 'He is called "Johnny"'
}

Single quotes

single quotes allow you to use the syntax of expressions within them.
The @ sign must be placed before the expressions.

dynamic
{
    item(title = 'windows dir path: @sys.dir')
}

Double quotes

double quotes allow you to use the Escape Character inside them only.
The backslash (\) escape character turns special characters into characters.
The sequence \" inserts a double quote in a string:

var
{
    var1 = "hello\"world"
    // result: hello"world
}

The complete set of escape sequences is as follows:

\'Single quote
\"Double quote
\\Backslash
\0Null
\aAlert
\bBackspace
\fForm Feed
\nNew Line
\rCarriage Return
\tHorizontal Tab
