RuboCop is a static code analyzer and linter for Ruby. It functions as a static analysis tool designed to detect potential bugs, identify style violations, and improve overall code quality in Ruby projects.
The project provides an automated code formatter that rewrites source code to align with established community standards. It also implements a language server protocol to surface linting and formatting errors directly within text editors.
Its capabilities cover automated code linting and the analysis of Ruby code style to ensure consistency across a project. These functions are driven by a rule-based engine and a configuration-driven policy.
