## What it is
An asynchronous linter plugin for Neovim (>= 0.9.5) that spawns external linters, parses their output, and reports results via vim.diagnostic. It complements the built-in LSP client for languages without language servers or where standalone linters give better results.

## Use cases
- run external linters in neovim
- show lint diagnostics in neovim buffers
- lint files without a language server
- complement LSP with standalone linters
- configure linters per filetype in neovim
- lint on save with BufWritePost autocmd

## When to choose
- you use Neovim and want lightweight async linting without ALE's bundled LSP client
- your language lacks a language server or standalone linters give better results
- you want diagnostics integrated with vim.diagnostic

## When to avoid
- you need a full LSP client alongside linting (use ALE)
- you don't use Neovim
- you lint untrusted repositories without sandboxing, since linters execute local executables with your permissions
