regular expressions in a simple way: VerbalExpressions

Surfing to find new things, i found this important library.. amd i thought:
‘how is possible survive to regular expressions, without using this VerbalExpressions???

If you worked with regex, when you read the initial example.. the smile open your face…

 

VerbalExpression testRegex = VerbalExpression.regex()
                                                .startOfLine().then("http").maybe("s")
	           				.then("://")
	           				.maybe("www.").anythingBut(" ")
	           				.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\.)?(?:[^\ ]*)$

Is it very very fantastic?

enterprise logging using jboss tools

Reading the errors of wildfly – weld, sometimes you can see some NUMBERS to identify the error..

/**
* Log messages for Contexts
* Message Ids: 000200 – 000299
*/

@MessageLogger(projectCode = WELD_PROJECT_CODE)
public interface ContextLogger extends WeldLogger

 

@LogMessage(level = Level.TRACE)
@Message(id = 200, value = “Looked for {0} and got {1} in {2}”, format = Format.MESSAGE_FORMAT)
void contextualInstanceFound(Object param1, Object param2, Object param3);

Vert.x – From zero to (micro)-hero

Clement Escoffier, Julien VietVersion 0.5,August 30th, 2016

 

Let’s start from the beginning…. Vert.x. What’s Vert.x ? That’s a pretty good question, and probably a good start. If you go on the Vert.x web site, Vert.x is defined as “a toolkit for building reactive applications on the JVM”. This description is rather fuzzy no ? What’s atoolkit ? What are reactive applications ? In this lab, we are going to explain these words, and build an application using Vert.x illustrating what Vert.x is. This application is going to be composed by microservices. Another buzzword to be trendy ? No, Vert.x was promoting microservices before everyone and his dog jumped on the bandwagon…..
