JavaVerbalExpressions

VerbalExpressions is a Java library that helps to construct difficult regular expressions.

##Getting Started

Maven Dependency:

<dependency>
  <groupId>ru.lanwen.verbalregex</groupId>
  <artifactId>java-verbal-expressions</artifactId>
  <version>1.0</version>
</dependency>

You can use SNAPSHOT dependency with adding to pom.xml:

<repositories>
  <repository>
    <id>ossrh</id>
    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
  </repository>
</repositories>

##Examples

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

Builder can be cloned:

// Produce: (.*)$
VerbalExpression regex = regex(regex().anything().addModifier('i')).endOfLine().build();
