Refactoring Ruby Edition Epub 19: A Review




If you are a Ruby developer who wants to improve the design and quality of your code, you might be interested in reading Refactoring Ruby Edition Epub 19. This is an authoritative and updated version of Martin Fowler's classic refactoring book that uses Ruby examples and idioms throughout. In this article, we will review what refactoring is, what Refactoring Ruby Edition offers, how to get and read it in Epub format, and answer some frequently asked questions.




Refactoring Ruby Edition Epub 19



What is refactoring and why is it important?




Refactoring is the process of changing the structure of existing code without changing its behavior. It is done to improve the readability, maintainability, extensibility, performance, and testability of the code. Refactoring can also help you find and fix bugs, reduce complexity, eliminate duplication, enhance modularity, and adhere to coding standards.


The definition and benefits of refactoring




According to Martin Fowler, one of the authors of Refactoring Ruby Edition, refactoring is "a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior". He also states that "refactoring improves software design" by making it easier to understand, modify, reuse, and evolve.


Some of the benefits of refactoring are:


  • It improves the quality and reliability of your code by removing bad smells, such as long methods, large classes, duplicated code, complex conditionals, primitive obsession, feature envy, etc.



  • It increases your productivity and efficiency by reducing the time and effort required to add new features, fix bugs, or make changes to your code.



  • It enhances your creativity and satisfaction by allowing you to focus on solving problems rather than dealing with technical debt or legacy code.



  • It facilitates collaboration and communication by making your code more consistent, coherent, expressive, and understandable for yourself and others.



The challenges and best practices of refactoring




Refactoring can be challenging for several reasons. Some of them are:


  • It can be risky if you don't have a reliable set of tests to verify that your code still works as expected after each change.



  • It can be difficult if you don't have a clear understanding of the existing code or the desired design.



  • It can be tedious if you have to perform many small changes manually or repetitively.



  • It can be resisted if you or your stakeholders are reluctant to invest time or resources in improving code that already works.



Some of the best practices of refactoring are:


  • Build tests before you start refactoring and run them frequently to ensure that your code still behaves correctly.



  • Refactor in small and simple steps, applying one refactoring at a time, and committing your changes regularly.



  • Use automated tools and IDEs to help you perform refactorings faster and more accurately.



  • Explain and justify your refactoring decisions to your team and stakeholders, and show them the benefits of having better code.



What is Refactoring Ruby Edition and what does it offer?




Refactoring Ruby Edition is a book that teaches you how to refactor Ruby code using a detailed catalog of more than 70 proven Ruby refactorings. It is based on Martin Fowler's original refactoring book, but it uses Ruby examples and idioms throughout, not code adapted from Java or any other environment. It also shows you how to refactor Ruby on Rails code, which is a popular web development framework that uses Ruby.


The authors and background of the book




The authors of Refactoring Ruby Edition are Jay Fields, Shane Harvie, Martin Fowler, and Kent Beck. Jay Fields and Shane Harvie are experienced Ruby developers and consultants who have worked on various projects using Ruby and Rails. Martin Fowler is a renowned software engineer, author, speaker, and consultant who specializes in software design and architecture. Kent Beck is a pioneer of agile software development, test-driven development, and extreme programming. He is also the creator of JUnit, a popular testing framework for Java.


The book was published in October 2009 by Addison-Wesley Professional as part of the Addison-Wesley Professional Ruby Series. It is an updated and revised version of Martin Fowler's original refactoring book, which was published in 1999 and became a classic in the field of software engineering. The original book used Java as the main programming language for the examples, but the authors decided to create a new edition that uses Ruby instead, because they believe that Ruby is a more expressive and dynamic language that supports many powerful refactoring techniques.


The main features and contents of the book




The book has four main features that make it a valuable resource for Ruby developers who want to learn how to refactor their code:


A detailed catalog of more than 70 Ruby refactorings




The core of the book is a catalog of more than 70 refactorings that cover various aspects of Ruby code, such as methods, objects, data, conditionals, method calls, generalization, and Rails. Each refactoring has a name, a description, a motivation, a mechanics section that explains how to apply it step by step, an example that illustrates how it works with Ruby code, and references to related refactorings. The catalog is organized into chapters according to the type of refactoring.


Ruby-specific examples and idioms




The book uses Ruby examples and idioms throughout to demonstrate how to refactor Ruby code effectively. The examples are realistic and relevant to common Ruby scenarios, such as web development, testing, metaprogramming, DSLs, etc. The idioms are Ruby-specific features or conventions that make the code more concise, elegant, or expressive, such as blocks, symbols, mixins, modules, etc. The book also explains how to use some of the built-in tools and libraries that Ruby provides for refactoring, such as Rake, RDoc, IRB, etc.


How to refactor Ruby on Rails code




The book also shows you how to refactor Ruby on Rails code, which is a popular web development framework that uses Ruby as the programming language. Rails follows the MVC (Model-View-Controller) pattern and has many conventions and features that make web development easier and faster. However, Rails code can also become messy or complex over time if not refactored properly. The book provides some specific refactorings for Rails code, such as extracting partials, introducing named scopes, replacing conditions with polymorphism, etc.

Five unique FAQs about Refactoring Ruby Edition Epub 19




Q: Do I need to read Martin Fowler's original refactoring book before reading Refactoring Ruby Edition?


  • A: No, you don't need to read Martin Fowler's original refactoring book before reading Refactoring Ruby Edition. Refactoring Ruby Edition is a standalone book that covers the same concepts and techniques as the original book, but with Ruby examples and idioms. However, if you want to compare or contrast the Java and Ruby versions of the refactorings, you can read both books.



Q: Do I need to have prior experience with Ruby or Rails to read Refactoring Ruby Edition?


  • A: Yes, you need to have some prior experience with Ruby or Rails to read Refactoring Ruby Edition. The book assumes that you are familiar with the basic syntax and features of Ruby and Rails, and that you have some existing Ruby or Rails code that you want to refactor. The book is not a beginner's guide to Ruby or Rails, nor a comprehensive reference to all the aspects of Ruby or Rails.



Q: How can I apply the refactorings in Refactoring Ruby Edition to other programming languages?


  • A: Some of the refactorings in Refactoring Ruby Edition are general enough that they can be applied to other programming languages, such as extracting methods, introducing variables, renaming identifiers, etc. However, some of the refactorings are specific to Ruby or Rails, such as using blocks, symbols, mixins, modules, etc. To apply the refactorings to other programming languages, you need to understand the underlying principles and goals of each refactoring, and then adapt them to the syntax and features of your target language.



Q: How can I practice the refactorings in Refactoring Ruby Edition?


  • A: One way to practice the refactorings in Refactoring Ruby Edition is to use the code samples provided in the book or on the book's website. You can download the code samples from https://github.com/jayfields/refactoring-ruby and try to apply the refactorings to them. You can also use your own Ruby or Rails code as a source of practice. You can use various tools and IDEs to help you perform the refactorings faster and more accurately, such as Rake, RDoc, IRB, RuboCop, etc.



Q: Where can I find more resources on refactoring Ruby code?


  • A: Besides Refactoring Ruby Edition, there are other resources that you can use to learn more about refactoring Ruby code. Some of them are:



  • Refactoring.com: Martin Fowler's website that contains articles, videos, podcasts, and other resources on refactoring.



  • Refactoring.Guru: A website that provides a catalog of refactorings with examples in various languages, including Ruby.
