## What it is
none-ls.nvim is the community-maintained fork of null-ls.nvim, a Neovim plugin that turns Neovim itself into a language server so non-LSP tools can inject diagnostics, code actions, formatting, hover, and completion via Lua. It includes built-in sources and helpers for wrapping command-line tools into LSP-compatible output.

## Use cases
- run linters in neovim without a language server
- format code inside neovim using external formatters
- get code actions from non-LSP tools in neovim
- bridge command-line tools into neovim's LSP client
- replace null-ls.nvim with a maintained fork
- add project-level diagnostics to neovim via lua

## When to choose
- you use Neovim and want diagnostics, formatting, or code actions from tools that don't speak LSP
- you want to avoid spawning separate language servers for simple lint/format tasks
- you were using null-ls.nvim and need a maintained replacement
- you want to write custom LSP sources in pure Lua

## When to avoid
- your tooling already has a proper language server with full feature support
- you don't use Neovim
- you need a production-guaranteed LSP implementation rather than a community-maintained beta plugin
