# Primitives

Primitives are fundamental types like booleans, integers and strings.

# Booleans

A boolean can either be true or false. It is comparable to a yes/no or on/off state.

# EBNF Notation

boolean = "true" | "false" ;

# Example

true
false

# Integers

Integers can be any valid whole number. They can not start with the digit 0.

# EBNF Notation

integer = "0" | [ "-" ] , "1".."9" , { "0".."9" } ;

# Example

0
-54
13

# Strings

A string is a sequence of characters. Strings are the basic of any text in the language. Strings are enclosed between single quotation marks '. To use variables inside of string you'll have to use the dollar sign, $ ,follow by variable castable to string. When using methods or accessing properties on an object the expression must be enclosed between curly brackets ${}. There are a set of restricted characters in Strings that should be escaped using a \, see Escape-sequences.

# EBNF Notation

escape = "\\" , "b" | "f" | "n" | "r" | "t" | "v" | "\\" | "'" ;
name = "a".."z" | "A".."Z" , { "a".."z" | "A".."Z" | "0".."9" } ;
template = "$" , name | ( "{" , expression, "}" ) ;
string = "'" , { any_character | template | escape } , "'" ;

_{any_character means all characters of the current character set
except for backslash, singlequote and dollar sign.}

# Example

'Hello, World!'

'Hello, $name'
'Hello, ${[expression]}'

_{See expression for details about expressions.}
