rufo
An opinionated Ruby code formatter that enforces a consistent style with minimal configuration.
What is rufo?
Rufo is an opinionated Ruby formatter designed for command-line use and editor integration to automatically format Ruby code on save or demand. It aims to establish a standardized 'one true format' for Ruby, similar to tools like gofmt and Prettier, to reduce style debates and enforce consistency with minimal configuration. It uses Ruby's Ripper parser and lexer for fast performance and preserves intentional code alignment by default.
Ruby developers and teams seeking an automated, low-configuration code formatter to enforce consistent style across projects, particularly those integrating format-on-save in editors like Atom, Emacs, Sublime Text, Vim, or VS Code.
Developers choose Rufo for its zero-config approach that enforces a unified Ruby code style without the complexity of extensive configuration, its fast performance due to using Ruby's built-in Ripper parser, and its unobtrusive default behavior that preserves intentional alignment choices while still formatting poorly aligned code.
