Transformer: Matching by tokens vs match by character; also whitespace sensitivity

ID: 155

				
					using uCalcSoftware;

var uc = new uCalc();
// This examples shows the default match by
// token mode, as well as how to reconfigure
// it in order to do match by character
// along with a whitespace variation

var t = uc.NewTransformer();
var txt = "This is an island test, I said.";
t.FromTo("is", "<is>");

Console.WriteLine(t.Transform(txt));
Console.WriteLine("");

t.Tokens.Description = "Match by character";
t.Tokens.Add("."); // This overrides existing tokens
t.FromTo("is", "<is>");
Console.WriteLine(t.Tokens.Description);
Console.WriteLine(t.Transform(txt));
Console.WriteLine("");

// Note: whitespace sensitivity is off by default
// Whitespace token is re-introduced
// (after being overridden in the previous Token Add())
t.Tokens.Description = "By char + whitespace ignored";
t.Tokens.Add("[\\t\\v ]+", TokenType.Whitespace);
t.FromTo("is", "<{@Self}>");
Console.WriteLine(t.Tokens.Description);
Console.WriteLine(t.Transform(txt));
				
			
This <is> an island test, I said.

Match by character
Th<is> <is> an <is>land test, I said.

By char + whitespace ignored
Th<is> <is> an <is>land test, <I s>aid.
