lsp-ui provides the higher-level UI modules for Emacs lsp-mode, including sideline diagnostics, peek definitions/references, documentation popups, and imenu integration. It is activated automatically by lsp-mode and configurable via simple use-package setup.

Use cases

  • show flycheck diagnostics inline in emacs
  • peek definitions and references in emacs
  • show hover documentation popup in emacs
  • display LSP code actions on current line
  • navigate cross references with jump list in emacs

When to choose

  • you use lsp-mode in Emacs and want richer UI for diagnostics, docs, and code navigation
  • you want VS Code-style peek definitions in Emacs
  • you want inline sideline display of hover info and code actions

When to avoid

  • you use a different editor or LSP client outside Emacs
  • you prefer minimal UI without sideline or doc popups
  • you use eglot instead of lsp-mode
