Ruby and Rails Standards: Language 10

C65 LLC

Coding Standards now covers 10 languages with the addition of Ruby (including Rails-specific standards).

What’s New

Section titled “What’s New”

Ruby standards (lang-10) cover idiomatic Ruby patterns: method naming, block usage, exception handling, Sorbet/RBS typing, and RuboCop configuration. The standard follows community conventions — snake_case methods, ? and ! suffixes, frozen string literals.

Ruby on Rails standards (lang-11) complement the base Ruby standard and address Rails-specific patterns: Active Record best practices, controller/service object boundaries, view helpers vs. presenters, Action Cable conventions, and Rails security (strong parameters, CSRF, SQL injection via Active Record).

Both standards include security sections with Brakeman for SAST and bundler-audit for dependency scanning.

File Numbering Restructure

Section titled “File Numbering Restructure”

Adding Ruby required renumbering some existing standards to maintain alphabetical ordering within the lang-XX prefix scheme. The restructure keeps the numbering consistent and leaves room for future additions.

Coverage

Section titled “Coverage”

With Ruby and Rails, the framework now covers:

Python, Java, Kotlin, Swift, Dart, TypeScript, JavaScript, Rust, Zig, Ruby/Rails

All 10 language standards share the same structure: naming conventions, architecture patterns, testing requirements, error handling, and a security section referencing the P0-P2 severity model.
