rubyfmt is a fast, opinionated autoformatter for Ruby source code, written in Rust. It runs as a CLI tool and integrates with editors like VS Code and Neovim.

Use cases

• format ruby files automatically
• autoformat ruby code on save
• enforce consistent ruby code style
• format ruby code from the command line
• format ruby code in neovim or vscode
• check formatting diffs for ruby files

When to choose

• you want a fast, opinionated Ruby formatter with editor integration
• you need CLI-based formatting with gitignore support and per-file opt-in/out
• you prefer a Rust-based alternative to RuboCop's formatter

When to avoid

• you need highly configurable formatting rules rather than opinionated defaults
• you need a linter, not just a formatter
• your team standardizes on RuboCop or another Ruby-native formatter
