幫助構建復雜正規表達式的Java類庫：JavaVerbalExpressions

VerbalExpressions是一個Java類庫，能夠幫助構建復雜正規表達式。

VerbalExpression testRegex = VerbalExpression.regex()
                                                .startOfLine().then("http").maybe("s")
                            .then("://")
                            .maybe("www.").anythingButNot(" ")
                            .endOfLine()
                            .build();

// Create an example URL
String url = "https://www.google.com";

// Use VerbalExpression's testExact() method to test if the entire string matches the regex
testRegex.testExact(url); //True

testRegex.toString(); // Outputs the regex used:
                      // ^(?:http)(?:s)?(?:\:\/\/)(?:www\.)?(?:[^\ ]*)$

VerbalExpression testRegex = VerbalExpression.regex()
                                                .startOfLine().then("abc").or("def")
                                                .build();

String testString = "defzzz";

//Use VerbalExpression's test() method to test if parts if the string match the regex
testRegex.test(testString);       // true
testRegex.testExact(testString);  // false
testRegex.getText(testString);    // returns: def
