Confessions of a Ruby Sadist sudo gem install flog
Flog shows you the most torturous code you wrote. The more painful the code, the higher the score. The higher the score, the harder it is to test. Run it against your best stuff. I double-dog dare you. Flog essentially scores an ABC metric: Assignments, Branches, Calls, with particular attention placed on calls. Run flog on all your code. Try this: find lib -name \*.rb | xargs flog Whatever is at
Refactoring From Inheritance To Composition To Data
“Prefer composition over inheritance” is a popular saying amongst programmers. In this article, I want to demonstrate what that looks like. We’re going to refactor some Rails classes from inheritance to composition. Then we’ll refactor again from composition to something even better: data. Inheritance (The Original Code) In an attempt to show “real” code, I’ve taken this example from the Rails cod
Railsで効率的かつ安全に未使用のメソッドを削除した話 - てくすた
ピクスタ開発部で毎日ヒィヒィ言いながらエンジニアをやっております @muramurasan です。 今回はPIXTAのとあるリポジトリにおいて、未使用のメソッドを削除しようとした際、gemを組み合わせることで、効率的かつ安全に削除することができたという話をしたいと思います。 よくやる方式 外部の勉強会などで、「未使用のメソッドを削除する際にどうしているか？」ということを聞いた際、よく聞くのが「未使用らしきコードを見つけ次第、ロギングを行うメソッド呼び出しを挟み込んでいく」というものでした。 この方式は、動的なメソッド呼び出しにも当然対応できますし、お手軽なので、一般的に好まれているようです。 問題点 ただし、この方式では以下の問題点があると私は考えています。 そもそも、未使用らしいメソッドを見つけるのが大変 プロダクションコードを汚してしまう これらの問題を解決するために、PIXTAでは
Why classes eventually reach 50 columns and hundreds of methods
Why classes eventually reach 50 columns and hundreds of methods … and check why 5600+ Rails engineers read also this Why classes eventually reach 50 columns and hundreds of methods There are dozens of small or bigger problems that we can have in our code. Like diseases, they affect our applications and make them harder to maintain, expand and enjoy. They give us a headache and they give bugs to ou
Refactoring Legacy Rails Controllers
Ruby on Rails controllers are like the bouncers of a nightclub. No identification at a club? You aren’t getting in. Without the proper clothes, you can expect to be turned away. Oh, you wanna say something slick? You’re definitely not getting in, and you might be getting a beatdown on your way out. Controllers are the bouncers of the Rails software stack. You aren’t logged in? See ya. You aren't a
7 Design Patterns to Refactor MVC Components in Rails — SitePoint
In our previous post, The Basics of MVC in Rails, we discussed theoretical aspects of the MVC design pattern. We defined what MVC stands for, identified what each MVC component is responsible for, addressed what happens when a component contains redundant logic, and, most importantly, we introduced the concept of refactoring. In this article, as promised, we’ll show you each design pattern at work
GitHub - seattlerb/debride: Analyze code for potentially uncalled / dead methods, now with auto-removal.
% debride lib These methods MIGHT not be called: MyClass good_method lib/some/file.rb:16 bad_method lib/some/file.rb:20 ... But you know that good_method is called (perhaps because it is public API), then you can whitelist it: % echo good_method > whitelist.txt % debride --whitelist whitelist.txt lib These methods MIGHT not be called: MyClass bad_method lib/some/file.rb:20 ... Usage example for a

Nobody knows bad code like Justin Searls—he writes bad code effortlessly. And it's given him the chance to study why the industry has gotten so good at making bad software. He co-founded Test Double, an agency focused on fixing what's broken in software. Until recently, we didn't talk much about "legacy Ruby". But today, so many companies rely on Ruby that legacy code is inevitable. When code is h
