lsp-mode is an Emacs client for the Language Server Protocol, providing IDE-like features such as completion, diagnostics, code navigation, and refactoring across many programming languages. It integrates with popular Emacs packages like company, flycheck, and lsp-ui.

Use cases

  • add IDE features to Emacs
  • get code completion and diagnostics in Emacs
  • use language servers with Emacs
  • set up LSP for Python, Java, Rust, or TypeScript in Emacs
  • navigate and refactor code in Emacs like an IDE
  • enable linting and code actions in Emacs

When to choose

  • you use Emacs and want full LSP v3.14 support
  • you want broad multi-language coverage from one package
  • you prefer deep integration with company, flycheck, and projectile

When to avoid

  • you use a different editor with native LSP support
  • you want a minimal Emacs setup without language servers
  • you need an IDE outside of Emacs
