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 - via lsp-execute-code-action, modeline (recommended) 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
  • Project errors on modeline
  • Debugger - dap-mode
  • Breadcrumb on headerline
  • Helm integration - helm-lsp
  • Ivy integration - lsp-ivy
  • Treemacs integration - lsp-treemacs
  • Semantic tokens as defined by LSP 3.16 (compatible language servers include recent development builds of clangd and rust-analyzer)
  • which-key integration for better discovery
  • iedit
  • dired
  • ido

Support the project

The emacs-lsp organization has more than 20.000 lines of code, to keep all of this working, we need to implement new features and help the community on a lot of issues.
