arity(1)

💅 NAME 💅

okay so bestie, meet arity — it's literally a language server, a formatter, AND a linter for R, all in one little icon. yes, all three. main character energy fr fr 🎀

(this whole page lives in the General Commands Manual, section 1, iykyk 🦋)

---

✨ SYNOPSIS ✨

arity [--config] [--no-config] [--color] [-q|--quiet] [-v|--verbose]
[-h|--help] [-V|--version] <subcommands>

like, you give it some flags and then a subcommand and it just goes 🫶

🌸 DESCRIPTION 🌸

Arity: a language server, formatter, and linter for R

that's the vibe check. that's the whole thing. no cap. ⭐

---

💅 OPTIONS 💅

• --config <PATH> — points at an explicit arity.toml. like, you're being specific about it: this skips discovery and also skips ARITY_CONFIG. you know exactly what you want and honestly? respect. 👑
• --no-config — ignores all config files, including ARITY_CONFIG, and just uses the built-in defaults. full chaos mode but make it consistent 🙈
• --color <WHEN> — tells it when to use color in output. [default: auto]

possible values, bestie:

• auto: colorizes when writing to a terminal and NO_COLOR is unset (this is the default one 💖)
• always: always colorizes. no thoughts, just rainbow 🌈
• never: never colorizes. monochrome era 🖤

• -q, --quiet — suppresses informational output (errors still show up, don't worry). BUT — and this is the little detail everyone misses — under format --check this drops the per-file diff, so you're left with the list of files that would be reformatted plus the summary. concise queen behavior 💅
• -v, --verbose — prints extra informational output (e.g. per-command summaries). some of us just want to know everything and that's valid 🍓
• -h, --help — prints help (see a summary with '-h')
• -V, --version — prints version

---

🦋 SUBCOMMANDS 🦋

• arity-parse(1) — parses and displays the CST tree, for debugging purposes 🔍
• arity-format(1) — formats R files and package DESCRIPTIONs ✨
