Crate arity_formatter 

Deterministic, rule-based formatter for the R language.

This crate is the formatting engine of arity, extracted so that other tools (e.g. a dprint plugin) can embed it. Output is decided solely by the formatter’s rules and its best-fit layout engine; the input’s existing line breaks never influence the result. The target style is the tidyverse R style guide.

The primary entry points are [format] and format_with_style, configured via FormatStyle. Their format_verified counterparts additionally check normalized syntax, ordinary comments, and idempotence. With the serde feature, FormatStyle is (de)serializable; the schema feature additionally derives schemars::JsonSchema.

A package’s DESCRIPTION is a second grammar with its own entry point, format_description; see formatter::description.
