## About
Companion plugin for [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) that allows you to seamlessly install
LSP servers locally (inside `:echo stdpath("data")`).
On top of just providing commands for installing & uninstalling LSP servers, it:
- provides a graphical UI
- optimized for blazing fast startup times
- supports installing custom versions of LSP servers (for example `:LspInstall rust_analyzer@nightly`)
- common install tasks are abstracted behind composable Lua APIs (has direct integration with libuv via vim.loop)
- minimum requirements are relaxed by attempting multiple different utilities (for example, only one of `wget`, `curl`, or `Invoke-WebRequest` is required for HTTP requests)
- <img src="https://user-images.githubusercontent.com/6705160/131256603-cacf7f66-dfa9-4515-8ae4-0e42d08cfc6a.png" height="20"> full support for Windows
## Installation
Requires neovim `>= 0.5.0` and [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig). The full requirements to
install all servers are:
- For Unix systems: bash(1), git(1), curl(1) or wget(1), unzip(1), tar(1), gzip(1)
- For Windows systems: powershell, git, tar, and [7zip][7zip] or [peazip][peazip] or [archiver][archiver] or [winzip][winzip]
- Node.js (LTS) & npm
- Python3 & pip3
- go
- javac
- Ruby & gem
[7zip]: https://www.7-zip.org/
[archiver]: https://github.com/mholt/archiver
[peazip]: https://peazip.github.io/
[winzip]: https://www.winzip.com/
### [Packer](https://github.com/wbthomason/packer.nvim)
```lua
use {
'neovim/nvim-lspconfig',
'williamboman/nvim-lsp-installer',
}
```
### vim-plug
```vim
Plug 'neovim/nvim-lspconfig'
Plug 'williamboman/nvim-lsp-installer'
```
## Usage
### 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
### Setup
```lua
local lsp_installer = require("nvim-lsp-installer")
-- Register a handler that will be called for all installed servers.
-- Alternatively, you may also register handlers on specific server instances instead (see example below).
lsp_installer.on_server_ready(function(server)
local opts = {}
-- (optional) Customize the options passed to the server
-- if server.name == "tsserver" then
-- opts.root_dir = function() ... end
-- end
-- This setup() function is exactly the same as lspconfig's setup function.
-- Refer to https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md
server:setup(opts)
end)
```
For more advanced use cases you may also interact with more APIs nvim-lsp-installer has to offer, for example the following (refer to `:help nvim-lsp-installer` for more docs).
```lua
local lsp_installer_servers = require'nvim-lsp-installer.servers'
local server_available, requested_server = lsp_installer_servers.get_server("rust_analyzer")
if server_available then
requested_server:on_ready(function ()
local opts = {}
requested_server:setup(opts)
end)
if not requested_server:is_installed() then
-- Queue the server to be installed
requested_server:install()
end
end
```
### Configuration
You can configure certain behavior of nvim-lsp-installer by calling the `.settings()` function.
_Make sure to provide your settings before any other interactions with nvim-lsp-installer!_
Refer to the [default configuration](#default-configuration) for all available settings.
Example:
```lua
local lsp_installer = require("nvim-lsp-installer")
lsp_installer.settings({
ui = {
icons = {
server_installed = "✓",
server_pending = "➜",
server_uninstalled = "✗"
}
}
})
```

[CUSTOM_SERVERS.md](./CUSTOM_SERVERS.md) for more information.
## Logo
Illustrations in the logo are derived from [@Kaligule](https://schauderbasis.de/)'s "Robots" collection.
## Roadmap
- Command (and corresponding Lua API) to update outdated servers (e.g., `:LspUpdate {server}`)
- More helpful metadata displayed in the UI window
- Cross-platform CI for all server installers
## Default configuration
```lua
local DEFAULT_SETTINGS = {
ui = {
icons = {
-- The list icon to use for installed servers.
server_installed = "◍",
-- The list icon to use for servers that are pending installation.
server_pending = "◍",
-- The list icon to use for servers that are not installed.
server_uninstalled = "◍",
},
keymaps = {
-- Keymap to expand a server in the UI
toggle_server_expand = "<CR>",
-- Keymap to install a server
install_server = "i",
-- Keymap to reinstall/update a server
update_server = "u",
-- Keymap to uninstall a server
uninstall_server = "X",
},
},
-- The directory in which to install all servers.
install_root_dir = path.concat { vim.fn.stdpath "data", "lsp_servers" },
pip = {
-- These args will be added to `pip install` calls. Note that setting extra args might impact intended behavior
-- and is not recommended.
--
-- Example: { "--proxy", "https://proxyserver" }
install_args = {},
},
-- Controls to which degree logs are written to the log file. It's useful to set this to vim.log.levels.DEBUG when
-- debugging issues with server installations.
log_level = vim.log.levels.INFO,
-- Limit for the maximum amount of servers to be installed at the same time. Once this limit is reached, any further
-- servers that are requested to be installed will be put in a queue.
max_concurrent_installers = 4,
}
```
