## What it is
A Language Server Protocol implementation for Lua, written in Lua, providing features like autocompletion, type checking, diagnostics, formatting, and go-to-definition. It works with any LSP-compatible editor such as VS Code and Neovim.

## Use cases
- get Lua autocompletion and hover docs in my editor
- type check my Lua codebase
- lint and format Lua code
- rename Lua symbols across a project
- generate documentation from Lua annotations
- set up Lua language support in Neovim

## When to choose
- you write Lua in VS Code, Neovim, or any LSP-capable editor
- you need type checking and diagnostics for Lua 5.1 through 5.5 or LuaJIT
- you want annotation-based documentation generation for Lua

## When to avoid
- you need language support for a language other than Lua
- your editor does not support the Language Server Protocol

## Facets
- artifact type: application
- maturity: stable
- function: linter, formatter, editor, type-system, documentation, developer-tools
- domain: programming-languages, developer-tools, text-editors, parsers
- platform: cross-platform, editor-plugin, cli, windows
