String

Strings are defined as an array of characters:

type str = char[]

Of course, this is all internal, and they will be represented to you as "string". However, this will allow you to access the length of the string with <string>.len.

str my_string = "cookie 🍪"

for i in my_string {
  @print(my_string[i])
}
// c
// o
// o
// k
// i
// e
//
// 🍪

Format strings

You can insert values into format strings using {<value>}:

@print("This is a string with a number inside: {5 + 2}")
// This is a string with a number inside: 7

If you’d like to escape the {} characters, you can simply add a backslash \{}:

@print("This is an escaped string with an expression inside: \{5 + 2}")
// This is an escaped string with an expression inside: {5 + 2}

Multiline strings

You can declare a multiline string using """. This will also dedent the string to the position of the closing """, and also escape any " inside. For example:

str my_string = """
  Hello World
    Indented line
  Unindented line
  """

@print(my_string)

will output

Hello World
  Indented line
Unindented line

You can also use values inside multiline strings using the same syntax as described in Format strings. For example:

@print("""
3 + 5 = {3 + 5}
8 + 10 = {8 + 10}
""")

will output:

3 + 5 = 8
8 + 10 = 18
