arity-cli

Arity is a language server, formatter, and linter for the R programming language.

Install

npm install -g arity-cli

This installs the arity command globally. The package detects your platform at install time and pulls in a prebuilt binary via npm's optional dependencies --- no Rust toolchain or postinstall download required.

You can also use it without a global install:

npx arity-cli format file.R

Usage

arity format file.R             # format in place
arity format <file.R            # read stdin, write stdout
arity format --check path/      # check without writing
arity lint --check file.R       # lint
arity lsp                       # start the language server

See arity --help and the documentation for the full feature list and configuration reference.
