String

Strings are defined as an array of characters. 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 myString = "cookie 🍪"

for i in myString {
  print(myString[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}

All values are converted to strings using the str() function when passed into a format string. If you'd like to use your own format, you can convert your value to a string yourself before passing it into the format string. For example:

fn intToDeciamlStr(int a) -> str {
  return str(decimal(a))
}

print("My number is {intToDecimalStr(10)}")
// "My number is 10.0

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 myString = """
  Hello World
    Indented line
  Unindented line
  """

print(myString)

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
