In 1994, Design Patterns replaced the panorama of object-oriented improvement via introducing vintage recommendations to habitual layout difficulties. In 1999, Refactoring revolutionized layout through introducing an efficient strategy for bettering code. With the hugely expected Refactoring to Patterns , Joshua Kerievsky has replaced our method of layout through eternally uniting styles with the evolutionary means of refactoring.

This booklet introduces the speculation and perform of pattern-directed refactorings: sequences of low-level refactorings that let designers to soundly movement designs to, in the direction of, or clear of development implementations. utilizing code from real-world tasks, Kerievsky records the pondering and steps underlying over dozen pattern-based layout differences. alongside the way in which he deals insights into trend transformations and the way to enforce styles within the least difficult attainable ways.

Coverage comprises:

  • A catalog of twenty-seven pattern-directed refactorings, that includes real-world code examples
  • Descriptions of twelve layout smells that point out the necessity for this book’s refactorings
  • General details and new insights approximately styles and refactoring
  • Detailed implementation mechanics: how low-level refactorings are mixed to enforce high-level styles
  • Multiple how you can enforce a similar pattern–and whilst to exploit every one
  • Practical how you can start whether you will have little adventure with styles or refactoring

Refactoring to Patterns displays 3 years of refinement and the insights of greater than sixty software program engineering inspiration leaders within the worldwide styles, refactoring, and agile improvement groups. no matter if you’re interested in legacy or “greenfield” improvement, this booklet will make you a greater software program dressmaker through assisting you tips on how to make very important layout adjustments appropriately and effectively.

You'll find out how to:
–Use the interactive Ruby shell (irb) to benefit key beneficial properties of the language
–Extend Ruby utilizing RubyGems, the Ruby package deal manager
–Create numerical utilities, in addition to utilities that technique and learn HTML/XML
–Implement merely useful and metaprogramming concepts to save lots of time and effort
–Optimize, profile, and attempt your code to ensure that it not just does its task, yet does it well
–Create internet purposes utilizing Rails

Ruby is the quickest becoming programming language this present day, and for strong cause: its based syntax and readable code make for prolific and chuffed programmers. however it will be obscure and enforce with out a little aid. Ruby by means of instance indicates you ways to exploit Ruby as you discover Ruby's basic ideas in action.

Um dos grandes desafios nos cursos de Tecnologia da Informação e em cursos correlatos é o ensino do paradigma orientação a objetos. Aprender o conceito de classe, objeto, herança, polimorfismo e outros conceitos do paradigma não basta. É necessário entender a aplicabilidade desses conceitos em dividir o software program em pequenas unidades que trocam mensagens entre si, aproveitando as reais vantagens desse paradigma.

Ao contrário do que ocorre em outras obras semelhantes, este livro introdutório não se prende às limitações de uma determinada linguagem. Para isso, esta obra explica os conceitos fazendo uso de códigos-fonte nas linguagens C++ e Python, ficando o leitor livre para reescrever os exemplos apresentados em sua linguagem orientada a objetos favorita.

Com uma linguagem casual, este livro tem nove capítulos e um capítulo de exercícios. No capítulo de exercícios, o autor associa a dificuldade de cada exercício a um objetivo educacional, fazendo uso da mesma metodologia usada em sala de aula.

O paradigma orientação a objetos comumente é ensinado aos alunos de graduação no terceiro semestre, quando estes já têm conhecimento de pelo menos uma linguagem estruturada (C, Pascal, entre outras). Assim, é recomendado ao leitor um contato prévio com alguma linguagem de programação.

Os códigos-fonte apresentados são escritos para Python 3.4 e C++ na versão C++11, disponíveis no git-hub para obtain e alterações, potencializando sua experiência de aprendizado.
