## What it is
StyLua is a deterministic, opinionated code formatter for Lua and its dialects (Lua 5.1-5.4, LuaJIT, Luau, CfxLua), written in Rust and built on the full-moon parser. It parses code and reprints it from scratch to enforce a consistent style, similar to Prettier.

## Use cases
- format lua code
- enforce consistent lua code style
- format luau scripts for roblox
- add lua formatting to ci pipeline
- set up pre-commit hook for lua formatting
- auto-format lua files in editor

## When to choose
- you write Lua or Luau and want Prettier-like deterministic formatting
- you need CI or pre-commit integration for Lua style enforcement
- you work across multiple Lua dialects including LuaJIT and FiveM

## When to avoid
- you need a configurable formatter with many style presets rather than an opinionated one
- your project is not Lua-based

## Facets
- artifact type: cli-tool
- maturity: active
- function: formatter, cli, parser
- domain: developer-tools, programming-languages
- platform: cli, windows, rust
- tags: lua, luau, code-style, prettier-inspired, pre-commit, roblox, command-line, linux, macos
