In the case of your application behavior, there are many ways in which this can come in handy. Why bother logging? Basically, we log for the same reasons we record any kind of information -so we can get back to it later. I donРІР‚в„ўt really feel the need to add more to it, which frees us to get to a more interesting question: why log? WhatРІР‚в„ўs the Motivation for Logging? This definition is, in my opinion, as good as it gets itРІР‚в„ўs short, easy, and to the point. In this particular case I wonРІР‚в„ўt, though, since the one I like the most is the definition given in the first post of the series:Р”Р„pplication logging involves recording information about your applicationРІР‚в„ўs runtime behavior to a more persistent medium. I often use WikipediaРІР‚в„ўs definitions in posts since theyРІР‚в„ўre reasonably well written and can serve nicely as a starting point for discussion. Feel good about yourself yet? What Is Application Logging? This is your first attempt at logging with Ruby. Open the file and you should see the greeting message. So, run the app again, type your name, and the app should continue behaving the exact same way.Р”В«ut now navigate to the project folder and youРІР‚в„ўll see a new file there, accompanying the projectРІР‚в„ўs source files: ThereРІР‚в„ўs also a new variable, РІР‚Сљmessage,РІР‚Сњ that exists just to avoid a duplication. WeРІР‚в„ўve just added a new line of text that writes the greeting to a file. Go back to the РІР‚СљGreeterРІР‚Сњ class and edit it so it looks like this: def greet(user) ThereРІР‚в„ўs no shortage of options, of course, but since this is a РІР‚Сљget logging as quickly as possibleРІР‚Сњ guide, we donРІР‚в„ўt really want to get fancy. We also need to register the greetings somewhere, which can really come in handy in several ways. But now letРІР‚в„ўs say someone decided this isnРІР‚в„ўt enough. Jokes aside, weРІР‚в„ўve got our little toy app up and running! It successfully displays a greeting to the user. Unless your name is also РІР‚СљCarlos,РІР‚Сњ in which case I congratulate your parents on their good taste in names.

Like the previous installments of the series, weРІР‚в„ўll create a very simple toy app in order to demonstrate how to log.Р”Р„s weРІР‚в„ўve just said, weРІР‚в„ўre going to start with a very primitive -though functional -approach, and weРІР‚в„ўll then evolve it toward a more sophisticated and realistic solution. Finally, a very simple yet realistic example of proper logging, with help from the Ruby РІР‚СљLoggerРІР‚Сњ class.A discussion on the fundamentals of logging: why bother logging, which data to log, and where to log.How to implement a very rudimentary logger.TodayРІР‚в„ўs post will follow the basic structure thatРІР‚в„ўs been used in the previous articles. ThatРІР‚в„ўs exactly what weРІР‚в„ўre doing today by teaching you how to get up and running with logging, using the Ruby programming language.

So, what about tipping the scale to the side of dynamically-typed interpreted languages? After that, we proceeded to cover Java, and then we wrote about Python. Time for us to continue with our ongoing series, in which we teach you how to get started logging quickly in a variety of programming languages.
