vim-lsp

vim-lsp is a Language Server Protocol client for Vim 8 and Neovim that brings modern IDE-style features into a lightweight editor. It uses Vim’s async jobs and timers (or Neovim’s RPC) to talk to external language servers without blocking the UI. Integrates with external completion frameworks for omnifunc/completion menus. With a server configured, you get go-to-definition, hover docs, signature help, references, rename, code actions, and diagnostics. It is designed to be minimal and extensible, often paired with completion plugins like asyncomplete or others for a full experience. Works with many language servers via simple server configuration blocks. The project aims to stay close to the LSP spec while exposing familiar Vim commands and mappings. It allows per-project or per-filetype setups, so multiple languages can be enabled side by side.
