/// # Patterns
///
/// `,`, it means one space, it formats the elements, which is before, space-split.
/// And insert a space after the prefix, unless it is at last.
///
/// `=>`, it means empty string, it formats the element, witch is before, without any split.
/// And insert nothing between two element.
///
/// `;`, it means newline(\n), it formats the element, witch is before, newline-split.
/// And insert a newline after the prefix, unless it is at last.
