Library: format
w::format
is the main entry point for string interpolation in Wayward. It has two main modes of operation: Numbered and Named interpolation.
w::format
uses the standard operator<<(std::ostream&)
interface internally to convert arguments to strings. This may or may not change in the future.
Numbered Interpolation
This performs positional interpolation, and expects string placeholders in the format {n}, where n is a number starting at 0.
Example:
w::format("Hello, {0}!", "World"); // => "Hello, World!"
Example with numbers:
w::format("{0} + {1} = {2}", 123, 456, 579); // => "123 + 456 = 579"
Named Interpolation
Instead of positional arguments, w::format
also supports named arguments, like so:
w::format("Hello, {entity}! I am {subject}.", {
{"entity", "World"},
{"subject", "Simon"}
}); // => "Hello, World! I am Simon."
