About:
rubyfmt is a code formatter for the Ruby programming language. It automatically reformats Ruby source code to a consistent, canonical style, eliminating debates over formatting and improving code readability. The tool is written in Rust, providing fast performance and reliability for large codebases.
Key Features:
  • High-speed formatting written in Rust
  • Idiomatic and consistent style output
  • Supports modern Ruby syntax and features
  • CLI tool for easy integration into workflows
Use Cases:
  • Enforcing a consistent code style across a Ruby project
  • Automated formatting in CI/CD pipelines
  • Refactoring legacy code to modern style standards
Alternatives:
  • RuboCop – RuboCop is a static code analyzer and linter that can also perform autocorrections, whereas rubyfmt is a dedicated, opinionated code formatter focused solely on style.
  • Prettier – Prettier is a popular formatter for JavaScript and other web languages; rubyfmt serves the same purpose but is specifically designed for Ruby.
