An R formatter. Written in Rust.

This package provides the air command-line tool as a Python package, making it easy to install via pip or uv.

Install a global installation of air with uv:

uv tool install air-formatter

or with pip

pip install air-formatter

This puts air on the PATH, so you can run:

# Format R file
air format path/to/file.R

# Format all R files in a directory
air format path/to/directory/

Alternatively, invoke air via uvx for one-off formatting without a global install:

uvx --from air-formatter air format path/to/file.R

To use a specific version of air:

# Global install
uv tool install air-formatter@0.8.2

# One off runs
uvx --from air-formatter@0.8.2 air format path/to/file.R

Air is an opinionated R formatter built by Posit. For more information, see the main repository.
