SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

RuboCop helps teams maintain consistent Ruby code quality by detecting style violations, potential bugs, and maintainability issues, and by offering safe automatic corrections.

Core Features & Use Cases

Static analysis across Ruby projects (Rails, RSpec, and Performance) to enforce style and best practices.
Safe autocorrection to fix common issues without changing behavior, plus configurable rules and extensions.
Detailed offense reports with line numbers, severities, and suggested fixes to guide code reviews and refactoring.

Quick Start

Install and run RuboCop in your project to scan all Ruby files and optionally enable Rails/RSpec extensions for richer checks.

FAQPage Schema

How do I run Ruby code linting and auto-formatting for a Rails project?▼

Ruby code linting and auto-formatting for a Rails project involves scanning files for style violations and maintainability issues. Enabling Rails extensions applies specialized checks, and safe autocorrection automatically fixes common style and behavior issues.

What is static analysis for Ruby code and how does it detect style violations?▼

Static analysis for Ruby code detects style violations, potential bugs, and maintainability issues by parsing source files without executing them. It provides detailed offense reports with line numbers, severities, and suggested fixes to guide refactoring.

Can I use RuboCop to lint RSpec test files?▼

Yes, you can lint RSpec test files by enabling RSpec extensions for richer checks. This specialized static analysis enforces best practices and style consistency within your test suite while providing safe autocorrections.

Does Ruby static analysis support safe autocorrection for performance issues?▼

Yes, Ruby static analysis supports safe autocorrection for performance issues by applying performance context rules. It automatically fixes common inefficiencies without changing runtime behavior, ensuring code remains functional while improving speed.

How do I configure custom rules for Ruby code style violations?▼

You configure custom rules for Ruby code style violations by adjusting configurable rule settings within your project. This tailors static analysis, enables specific extensions, and aligns offense reports and autocorrections with team coding standards.

What are the limitations of safe autocorrection in Ruby static analysis?▼

Safe autocorrection in Ruby static analysis is limited to fixing common style and performance issues without changing runtime behavior. It cannot resolve complex logical bugs or maintainability issues, requiring manual refactoring guided by offense reports.
