ℹ️ Project status

This is an excerpt from the announcement here.

nvim-lsp-installer is no longer maintained.

mason.nvim is the next generation version of nvim-lsp-installer. It builds on top of the very same foundation as nvim-lsp-installer (which means it's easy to migrate), but with a majority of internals refactored to improve extensibility and testability.

More importantly, the scope of mason.nvim has also been widened to target more than just LSP servers. mason.nvim supports DAP servers, linters, formatters, and more. As of writing, mason.nvim provides 150+ packages for 100+ languages. It can be thought of as a general-purpose package manager, native to Neovim, that runs everywhere Neovim runs (Windows, macOS, Linux, etc.).

Another big change with mason.nvim is that executables are now linked to a single, shared, location, allowing seamless access from Neovim builtins (shell, terminal, etc.) as well as other 3rd party plugins.

There have also been other improvements such as broader test coverage, more documentation, and a revamped UI - check it out!

nvim-lsp-installer

About

Neovim plugin that allow you to manage LSP servers (servers are installed inside :echo stdpath("data") by default). It works in tandem with lspconfig1 by registering a hook that enhances the PATH environment variable, allowing neovim's LSP client to locate the server executable installed by nvim-lsp-installer.2

On top of just providing commands for installing & uninstalling LSP servers, it:

  • provides a graphical UI
  • provides the ability to check for, and upgrade to, new server versions through a single interface
  • supports installing custom versions of LSP servers (for example :LspInstall rust_analyzer@nightly)
  • relaxes the minimum requirements by attempting multiple different utilities (for example, only one of wget, curl, or Invoke-WebRequest is required for HTTP requests)
  • hosts a suite of system tests for all supported servers
  • has full support for Windows

1 - while lspconfig is the main target, this plugin may also be used for other use cases
2 - some servers don't provide an executable, in which case the full command to spawn the server is provided instead

  • For Windows systems: powershell, git, tar, and 7zip or peazip or archiver or winzip or WinRAR

Additional requirements

Additional requirements to install & run all servers are (depending on usage):

  • Node.js (LTS) & npm

Installation

use {
    "williamboman/nvim-lsp-installer",
    "neovim/nvim-lspconfig",
}

vim-plug

Plug 'williamboman/nvim-lsp-installer'
Plug 'neovim/nvim-lspconfig'

Usage

nvim-lsp-installer will only make sure that Neovim can find your installed servers, it does not set up any servers for you automatically. You will have to set up your servers yourself (for example via lspconfig).

Setup

In order for nvim-lsp-installer to register the necessary hooks at the right moment, make sure you call the require("nvim-lsp-installer").setup() function before you set up any servers!

require("nvim-lsp-installer").setup {}

Refer to the Configuration section for information about which settings are available.

Commands

  • :LspInstallInfo - opens a graphical overview of your language servers
  • :LspInstall [--sync] [server] ... - installs/reinstalls language servers. Runs in a blocking fashion if the --sync argument is passed (only recommended for scripting purposes).
  • :LspUninstall [--sync] <server> ... - uninstalls language servers. Runs in a blocking fashion if the --sync argument is passed (only recommended for scripting purposes).
  • :LspUninstallAll [--no-confirm] - uninstalls all language servers
  • :LspInstallLog - opens the log file in a new tab window
  • :LspPrintInstalled - prints all installed language servers

Configuration

You may optionally configure certain behavior of nvim-lsp-installer when calling the .setup() function.

Refer to the default configuration for all available settings.

Example:

require("nvim-lsp-installer").setup({
    automatic_installation = true, -- automatically detect which servers to install (based on which servers are set up via lspconfig)
    ui = {
        icons = {
            server_installed = "",
            server_pending = "",
            server_uninstalled = ""
        }
    }
})
