					using uCalcSoftware;

var uc = new uCalc();
var t = new uCalc.Transformer();
// Pattern: Capture first, optional middle, and last names.
// Replacement: The block `{middle: {middle}}` ensures a leading space is only added if a middle name exists.
t.FromTo("Name: {first:1} [{middle:1}] {last:1}",
"User: {last}, {first}{middle: {middle}}");

Console.WriteLine(t.Transform("Name: John Doe"));
Console.WriteLine(t.Transform("Name: John Quincy Adams"));
