Language servers

LunarVim uses filetype plugins to enable lazy-loading the setup of a language server. A template generator is used to create ftplugin files and populate them with the setup call.

lvim.lsp.automatic_configuration.skipped_servers contains a list of servers that will not be automatically configured by default, for example only tsserver is allowed for JS-family languages, and when a language has more than one server available, then the most popular one is usually chosen.

info

Any changes to lvim.lsp.automatic_configuration.skipped_servers must be followed by :LvimCacheReset to take effect.

Installing and updating a server‚Äč

Automatic installation‚Äč

By default, most supported language servers will get automatically installed once you open the supported file-type, e.g, opening a Python file for the first time will install pyright and configure it automatically for you.

Manual installation‚Äč

lvim.lsp.automatic_servers_installation = false

Please refer to mason to see the updated full list of currently available servers.

To install a supported language server:

:LspInstall `<your_language_server>`

You can also open :Mason and interactively choose which servers to install (press g? for keybindings).

Updating a server‚Äč

Open :Mason, select a server and update it with u. You can update all mason packages with <S-u>.

Changing the default server‚Äč

To use a different server than the default one add the default server to the skipped_servers list and remove the one you want to use.

info

Any changes to lvim.lsp.automatic_configuration.skipped_servers must be followed by :LvimCacheReset to take effect.

Example:

  • Use jedi_language_server instead of pyright

    -- add `pyright` to `skipped_servers` list
    vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "pyright" })
    -- remove `jedi_language_server` from `skipped_servers` list
    lvim.lsp.automatic_configuration.skipped_servers = vim.tbl_filter(function(server)
    return server ~= "jedi_language_server"
    end, lvim.lsp.automatic_configuration.skipped_servers)

Overriding settings‚Äč

Using :LspSettings‚Äč

To set settings for your language server:

:LspSettings <TAB>

Example:

  1. :LspSettings sumneko_lua

  2. {
    "Lua.hint.enable": false
    }

This will create a file in /lsp-settings to enable persistent changes. Refer to the documentation of nlsp-settings for a full updated list of supported language servers.

tip

Install jsonls LSP server for autocompletion.

By overriding the setup‚Äč

Add the server you wish to configure manually to lvim.lsp.automatic_configuration.skipped_servers.

vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "sumneko_lua" })
info

Any changes to lvim.lsp.automatic_configuration.skipped_servers must be followed by :LvimCacheReset to take effect.

Now you can set it up manually using the builtin lsp manager in $LUNARVIM_CONFIG_DIR/ftplugin/<filetype>.lua

Example:

-- $LUNARVIM_CONFIG_DIR/ftplugin/lua.lua
local opts = {
settings = {
Lua = { hint = { enable = false } },
},
}
require("lvim.lsp.manager").setup("sumneko_lua", opts)
