Showcase

Install In One Command!

Make sure you have the release version of Neovim (0.7+).

Linux:

bash <(curl -s https://raw.githubusercontent.com/lunarvim/lunarvim/master/utils/installer/install.sh)

To run the install script without any interaction you can pass the -y flag to automatically install all dependencies and have no prompts. This is particularly useful in automated installations.

The same way, you can use --no-install-dependencies to skip the dependency installation.

Windows (Powershell 7+):

Powershell v7+ is required for this script. For instructions on how to install, click here.

Automatic LSP support

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.

Configuration file

To install plugins configure LunarVim use the config.lua located here: ~/.config/lvim/config.lua

Example:

-- general
lvim.format_on_save = true
lvim.colorscheme = "onedarker"

lvim.leader = "space"
-- add your own keymapping
lvim.keys.normal_mode["<C-s>"] = ":w<cr>"
-- unmap a default keymapping
-- lvim.keys.normal_mode["<C-Up>"] = ""
-- edit a default keymapping
-- lvim.keys.normal_mode["<C-q>"] = ":q<cr>"
-- set keymap with custom opts
-- lvim.keys.insert_mode["po"] = {'<ESC>', { noremap = true }}

-- Use which-key to add extra bindings with the leader-key prefix
-- lvim.builtin.which_key.mappings["P"] = { "<cmd>Telescope projects<CR>", "Projects" }

-- Configure builtin plugins
lvim.builtin.alpha.active = true
lvim.builtin.notify.active = true
lvim.builtin.terminal.active = true

-- Treesitter parsers change this to a table of the languages you want i.e. {"java", "python", javascript}
lvim.builtin.treesitter.ensure_installed = "maintained"
lvim.builtin.treesitter.ignore_install = { "haskell" }

-- Disable virtual text
lvim.lsp.diagnostics.virtual_text = false

-- Select which servers should be configured manually. Requires `:LvimCacheReset` to take effect.
-- See the full default list `:lua print(vim.inspect(lvim.lsp.override))`
vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "pyright" })

-- set a formatter, this will override the language server formatting capabilities (if it exists)
local formatters = require "lvim.lsp.null-ls.formatters"
formatters.setup {
  { command = "black" },
  {
    command = "prettier",
    ---@usage specify which filetypes to enable. By default a providers will attach to all the filetypes it supports.
    filetypes = { "typescript", "typescriptreact" },
  },
}

-- set additional linters
local linters = require "lvim.lsp.null-ls.linters"
linters.setup {
  {
    command = "eslint_d",
    ---@usage specify which filetypes to enable. By default a providers will attach to all the filetypes it supports.
    filetypes = { "javascript", "javascriptreact" },
  },
}

-- Additional Plugins
lvim.plugins = {
    {"lunarvim/colorschemes"},
    {"folke/tokyonight.nvim"}, {
        "ray-x/lsp_signature.nvim",
        config = function() require"lsp_signature".on_attach() end,
        event = "BufRead"
    }
}
