Overview

Client for Language Server Protocol (v3.14). lsp-mode aims to provide IDE-like experience by providing optional integration with the most popular Emacs packages like company, flycheck and projectile.

  • Non-blocking asynchronous calls
  • Real-time Diagnostics/linting via flycheck (recommended) or flymake when Emacs > 26 (requires flymake>=1.0.5)
  • Code completion - company-capf / completion-at-point (note that company-lsp is no longer supported).
  • Hovers - using lsp-ui
  • Code actions - using lsp-execute-code-action or lsp-ui sideline.
  • Code outline - using builtin imenu or helm-imenu
  • Code navigation - using builtin xref, lsp-treemacs tree views or lsp-ui peek functions.
  • Code lens
  • Symbol highlights
  • Formatting
  • Debugger - dap-mode
  • Helm integration - helm-lsp
  • Ivy integration - lsp-ivy
  • Treemacs integration - lsp-treemacs
  • Semantic highlighting (using either the theia semantic highlighting protocol as implemented by JDT LS and some versions of clangd, or the semantic tokens protocol defined by LSP 3.16)
  • which-key integration for better discovery
