ALE (Asynchronous Lint Engine) is a Vim/Neovim plugin that provides asynchronous linting and syntax checking while you type, plus code fixing via external tools. It also acts as a Language Server Protocol client offering features like go-to-definition, completion, hover info, and symbol search.

Use cases

• lint code in vim while typing
• check syntax errors in neovim asynchronously
• fix and format files with prettier or eslint from vim
• get LSP go-to-definition and hover in vim
• show linter warnings before saving files
• autocomplete support in vim via language server
• find references and search symbols in neovim

When to choose

• you use Vim 8.2+ or Neovim 0.7+ and want zero-dependency asynchronous linting
• you want linting, fixing, and LSP features in a single plugin without a separate LSP client
• you want to only pay for the features you actually use

When to avoid

• you use a modern Neovim setup already built around the built-in LSP client and nvim-lint
• you use an editor other than Vim or Neovim
• you need a full-featured IDE-like LSP experience with advanced features beyond diagnostics and navigation
