Dollarstrings

Wirbel provides a syntax for embedding variables directly into strings - very much like in shell scripts:

name = "Hugo"
print($"His name was $name.")

The variables do not need to be of type string. They will be converted into strings automatically by making use of the function str:

years = 10
print($"And he was $years years old.")

You can even embedd expressions by enclosing them into braces:

print($"And that are ${years * 12} months.")

You can use arbitrary expressions as long as they do not contain braces or other strings.

Internally the Wirbel compiler parses dollar strings into expressions made of strings, + and calls to str. The previous example will produce exactly the same code as:

print("And that are " + str(years * 12) + " months.")

Dollar strings first appeared in Wirbel 0.1.10.
