## ✨ Features

- 📦 Manage all your Neovim plugins with a sleek and intuitive UI
- 🚀 Fast startup times thanks to automatic caching and bytecode compilation of lua modules.
- 💾 Partial clones instead of shallow clones
- 🔌 Automatic lazy-loading of lua modules and lazy-loading on events, commands, filetypes, and key mappings.
- ⏳ Automatically install missing plugins before starting up Neovim, allowing you to start using it right away.
- 💪 Async execution for improved performance
- 🛠️ No need to manually compile plugins
- 🧪 Correct sequencing of dependencies
- 📁 Configurable in multiple files
- 💻 Dev options and patterns for using local plugins
- 📊 Profiling tools to optimize performance
- 🔒 Lockfile `lazy-lock.json` to keep track of installed plugins
- 🔎 Automatically check for updates
- 📋 Commit, branch, tag, version, and full [Semver](https://devhints.io/semver) support
- 📈 Statusline component to see the number of pending updates

## ⚡️ Requirements

- Neovim >= **0.8.0**

## 📦 Installation

You can use the following Lua code to bootstrap **lazy.nvim**

<!-- bootstrap_start -->

```lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
 if not vim.loop.fs_stat(lazypath) then
   vim.fn.system({
     "git",
     "clone",
     "--filter=blob:none",
     "--single-branch",
     "https://github.com/folke/lazy.nvim.git",
     lazypath,
   })
   vim.opt.runtimepath:prepend(lazypath)
 end
```

<!-- bootstrap_end -->

Next step is to add **lazy.nvim** to the top of your `init.lua`

```lua
-- You can use a lua module that contains your plugins.
-- All sub modules of the lua module will also be automatically loaded
-- This is the preferred setup so your plugin specs can be properly cached.
require("lazy").setup("config.plugins", {
  -- add any optional configuration here
})

-- Alternatively you can specify a plugin list
require("lazy").setup({
    "folke/neodev.nvim",
    "folke/which-key.nvim",
    { "folke/neoconf.nvim", cmd = "Neoconf" },
  }, {
  -- add any optional configuration here
})
```

## 🔌 Plugin Spec

| Property | Type    | Description |
| -------- | ------- | ----------- |
| Item1.1  | Item2.1 | Item3.1     |
| Item1.2  | Item2.2 | Item3.2     |

<!-- spec_start -->

```lua
return {
  -- the colorscheme should be available when starting Neovim
  "folke/tokyonight.nvim",

  -- I have a separate config.mappings file where I require which-key.
  -- With lazy the plugin will be automatically loaded when it is required somewhere
  { "folke/which-key.nvim", lazy = true },

  {
    "nvim-neorg/neorg",
    -- lazy-load on filetype
    ft = "norg",
    -- custom config that will be executed when loading the plugin
    config = function()
      require("neorg").setup()
    end,
  },

  {
    "dstein64/vim-startuptime",
    -- lazy-load on a command
    cmd = "StartupTime",
  },

  {
    "hrsh7th/nvim-cmp",
    -- load cmp on InsertEnter
    event = "InsertEnter",
    -- these dependencies will only be loaded when cmp loads
    -- dependencies are always lazy-loaded unless specified otherwise
    dependencies = {
      "hrsh7th/cmp-nvim-lsp",
      "hrsh7th/cmp-buffer",
    },
    config = function()
      -- ...
    end,
  },

  -- you can use the VeryLazy event for things that can
  -- load later and are not important for the initial UI
  { "stevearc/dressing.nvim", event = "VeryLazy" },

  {
    "cshuaimin/ssr.nvim",
    -- init is always executed during startup, but doesn't load the plugin yet.
    -- init implies lazy loading
    init = function()
      vim.keymap.set({ "n", "x" }, "<leader>cR", function()
        -- this require will automatically load the plugin
        require("ssr").open()
      end, { desc = "Structural Replace" })
    end,
  },

  {
    "monaqa/dial.nvim",
    -- lazy-load on keys
    keys = { "<C-a>", "<C-x>" },
  },

  -- local plugins need to be explicitely configured with dir
  { dir = "~/projects/secret.nvim" },

  -- you can use a custom url to fetch a plugin
  { url = "git@github.com:folke/noice.nvim.git" },

  -- local plugins can also be configure with the dev option.
  -- This will use ~/projects/noice.nvim/ instead of fetching it from Github
  -- With the dev option, you can easily switch between the local and installed version of a plugin
  { "folke/noice.nvim", dev = true },
}
```

## ⚙️ Configuration

**lazy.nvim** comes with the following defaults:

<!-- config_start -->

```lua
{
  root = vim.fn.stdpath("data") .. "/lazy", -- directory where plugins will be installed
  defaults = {
    lazy = false, -- should plugins be lazy-loaded?
    version = nil,
    -- version = "*", -- enable this to try installing the latest stable versions of plugins
  },
  lockfile = vim.fn.stdpath("config") .. "/lazy-lock.json", -- lockfile generated after running update.
  concurrency = nil, ---@type number limit the maximum amount of concurrent tasks
  git = {
    -- defaults for the `Lazy log` command
    -- log = { "-10" }, -- show the last 10 commits
    log = { "--since=1 days ago" }, -- show commits from the last 3 days
    timeout = 120, -- kill processes that take more than 2 minutes
    url_format = "https://github.com/%s.git",
  },
  dev = {
    -- directory where you store your local plugin projects
    path = vim.fn.expand("~/projects"),
    ---@type string[] plugins that match these patterns will use your local versions instead of being fetched from GitHub
    patterns = {}, -- For example {"folke"}
  },
  install = {
    -- install missing plugins on startup. This doesn't increase startup time.
    missing = true,
    -- try to load one of these colorschemes when starting an installation during startup
    colorscheme = { "habamax" },
  },
  ui = {
    -- The border to use for the UI window. Accepts same border values as |nvim_open_win()|.
    border = "none",
    icons = {
      cmd = " ",
      config = "",
      event = "",
      ft = " ",
      init = " ",
      keys = " ",
      plugin = " ",
      runtime = " ",
      source = " ",
      start = "",
      task = "✔ ",
    },
    throttle = 20, -- how frequently should the ui process render events
  },
  checker = {
    -- automcatilly check for plugin updates
    enabled = false,
    concurrency = nil, ---@type number? set to 1 to check for updates very slowly
    notify = true, -- get a notification when new updates are found
    frequency = 3600, -- check for updates every hour
  },
  performance = {
    cache = {
      enabled = true,
      path = vim.fn.stdpath("state") .. "/lazy.state",
      -- Once one of the following events triggers, caching will be disabled.
      -- To cache all modules, set this to `{}`, but that is not recommended.
      -- The default is to disable on:
      --  * VimEnter: not useful to cache anything else beyond startup
      --  * BufReadPre: this will be triggered early when opening a file from the command line directly
      disable_events = { "VimEnter", "BufReadPre" },
    },
    reset_packpath = true, -- reset the package path to improve startup time
    rtp = {
      reset = true, -- reset the runtime path to $VIMRUNTIME and your config directory
      ---@type string[] list any plugins you want to disable here
      disabled_plugins = {
        -- "gzip",
        -- "matchit",
        -- "matchparen",
        -- "netrwPlugin",
        -- "tarPlugin",
        -- "tohtml",

## 📦 Differences with Packer

- **Plugin Spec**:

  - `setup` => `init`
  - `requires` => `dependencies`
  - `as` => `name`
  - `opt` => `lazy`
  - `run` => `build`
  - `lock` => `pin`
  - `module` is auto-loaded. No need to specify
