Standard Ruby is a linter and formatter built on RuboCop that gives projects a shared set of style rules. It removes the need for teams to choose and maintain their own formatting conventions, while also checking for potential errors and inefficient code.
Its style rules are fixed, but its operation is configurable. Projects can select files to check, exclude particular offences, and add extra checks through plugins. Existing codebases can adopt it gradually without correcting every historical violation at once.
This is free and open source software.
Key Features
- Automatic correction of many offences, with a separate option for fixes that may change program behaviour.
- Performance checks supplied through standard-performance and rubocop-performance.
- Command-line and Rake interfaces for checking individual files or directory trees, including use in continuous integration.
- Generates a todo file recording existing violations so teams can address them incrementally while detecting newly introduced problems.
- Targeted exclusions for individual lines, sections, files, and filename patterns, including suppression of specific rules.
- Ruby LSP integration provides inline diagnostics, formatting, and code actions for applying fixes within compatible editors.
- A standalone language server offers diagnostics and formatting for editors with Language Server Protocol support.
- Plugins such as standard-rails and standard-sorbet add specialised checks without overriding the default ruleset.
- Supports additional rules through configuration extensions, parallel checking, and alternative report formats including JSON.
- Cross-platform support – runs on Linux, macOS, and Windows.
