# 🚀 Usage

Plugins are managed with the `:Lazy` command.
Open the help with `<?>` to see all the key mappings.

You can press `<CR>` on a plugin to show its details. Most properties
can be hovered with `<K>` to open links, help files, readmes,
git commits and git issues.

Lazy can automatically check for updates in the background. This feature
can be enabled with `config.checker.enabled = true`.

Any operation can be started from the UI, with a sub command or an API function:

<!-- commands:start -->

| Command | Lua | Description |
| --- | --- | --- |
| `:Lazy build {plugins}` | `require("lazy").build(opts)` | Rebuild a plugin |
| `:Lazy check [plugins]` | `require("lazy").check(opts?)` | Check for updates and show the log (git fetch) |
| `:Lazy clean [plugins]` | `require("lazy").clean(opts?)` | Clean plugins that are no longer needed |
| `:Lazy clear` | `require("lazy").clear()` | Clear finished tasks |
| `:Lazy debug` | `require("lazy").debug()` | Show debug information |
| `:Lazy health` | `require("lazy").health()` | Run `:checkhealth lazy` |
| `:Lazy help` | `require("lazy").help()` | Toggle this help page |
| `:Lazy home` | `require("lazy").home()` | Go back to plugin list |
| `:Lazy install [plugins]` | `require("lazy").install(opts?)` | Install missing plugins |
| `:Lazy load {plugins}` | `require("lazy").load(opts)` | Load a plugin that has not been loaded yet. Similar to `:packadd`. Like `:Lazy load foo.nvim`. Use `:Lazy! load` to skip `cond` checks. |
| `:Lazy log [plugins]` | `require("lazy").log(opts?)` | Show recent updates |
| `:Lazy profile` | `require("lazy").profile()` | Show detailed profiling |
| `:Lazy reload {plugins}` | `require("lazy").reload(opts)` | Reload a plugin (experimental!!) |
| `:Lazy restore [plugins]` | `require("lazy").restore(opts?)` | Updates all plugins to the state in the lockfile. For a single plugin: restore it to the state in the lockfile or to a given commit under the cursor |
| `:Lazy sync [plugins]` | `require("lazy").sync(opts?)` | Run install, clean and update |
| `:Lazy update [plugins]` | `require("lazy").update(opts?)` | Update plugins. This will also update the lockfile |

<!-- commands:end -->

Any command can have a **bang** to make the command wait till it finished. For example,
if you want to sync lazy from the cmdline, you can use:

```shell
nvim --headless "+Lazy! sync" +qa
```

`opts` is a table with the following key-values:

- **wait**: when true, then the call will wait till the operation completed
- **show**: when false, the UI will not be shown
- **plugins**: a list of plugin names to run the operation on
- **concurrency**: limit the `number` of concurrently running tasks

Stats API (`require("lazy").stats()`):

<!-- stats:start -->

```lua
{
  -- startuptime in milliseconds till UIEnter
  startuptime = 0,
  -- when true, startuptime is the accurate cputime for the Neovim process. (Linux & macOS)
  -- this is more accurate than `nvim --startuptime`, and as such will be slightly higher
  -- when false, startuptime is calculated based on a delta with a timestamp when lazy started.
  real_cputime = false,
  count = 0, -- total number of plugins
  loaded = 0, -- number of loaded plugins
  ---@type table<string, number>
  times = {},
}
```

<!-- stats:end -->

**lazy.nvim** provides a statusline component that you can use to show the number of pending updates.
Make sure to enable `config.checker.enabled = true` to make this work.

<summary>Example of configuring <a href="https://github.com/nvim-lualine/lualine.nvim">lualine.nvim</a></summary>

```lua
require("lualine").setup({
  sections = {
    lualine_x = {
      {
        require("lazy.status").updates,
        cond = require("lazy.status").has_updates,
        color = { fg = "#ff9e64" },
      },
    },
  },
})

```

### 📆 User Events

The following user events will be triggered:

- **LazyDone**: when lazy has finished starting up and loaded your config
- **LazySync**: after running sync
- **LazyInstall**: after an install
- **LazyUpdate**: after an update
- **LazyClean**: after a clean
- **LazyCheck**: after checking for updates
- **LazyLog**: after running log
- **LazyLoad**: after loading a plugin. The `data` attribute will contain the plugin name.
- **LazySyncPre**: before running sync
- **LazyInstallPre**: before an install
- **LazyUpdatePre**: before an update
- **LazyCleanPre**: before a clean
- **LazyCheckPre**: before checking for updates
- **LazyLogPre**: before running log
- **LazyReload**: triggered by change detection after reloading plugin specs
- **VeryLazy**: triggered after `LazyDone` and processing `VimEnter` auto commands
- **LazyVimStarted**: triggered after `UIEnter` when `require("lazy").stats().startuptime` has been calculated.
  Useful to update the startuptime on your dashboard.

## ▶️ Startup Sequence

**lazy.nvim** does **NOT** use Neovim packages and even disables plugin loading
completely (`vim.go.loadplugins = false`). It takes over the complete
startup sequence for more flexibility and better performance.

In practice this means that step 10 of [Neovim Initialization](https://neovim.io/doc/user/starting.html#initialization) is done by Lazy:

1. All the plugins' `init()` functions are executed
2. All plugins with `lazy=false` are loaded. This includes sourcing `/plugin` and `/ftdetect` files. (`/after` will not be sourced yet)
3. All files from `/plugin` and `/ftdetect` directories in your rtp are sourced (excluding `/after`)
4. All `/after/plugin` files are sourced (this includes `/after` from plugins)

Files from runtime directories are always sourced in alphabetical order.

## 📂 Structuring Your Plugins

Some users may want to split their plugin specs in multiple files.
Instead of passing a spec table to `setup()`, you can use a Lua module.
The specs from the **module** and any top-level **sub-modules** will be merged together in the final spec,
so it is not needed to add `require` calls in your main plugin file to the other files.

The benefits of using this approach:

- Simple to **add** new plugin specs. Just create a new file in your plugins module.
- Allows for **caching** of all your plugin specs. This becomes important if you have a lot of smaller plugin specs.
- Spec changes will automatically be **reloaded** when they're updated, so the `:Lazy` UI is always up to date.

Example:

- `~/.config/nvim/init.lua`

```lua
require("lazy").setup("plugins")
```

- `~/.config/nvim/lua/plugins.lua` or `~/.config/nvim/lua/plugins/init.lua` **_(this file is optional)_**

```lua
return {
  "folke/neodev.nvim",
  "folke/which-key.nvim",
  { "folke/neoconf.nvim", cmd = "Neoconf" },
}
```

- Any lua file in `~/.config/nvim/lua/plugins/*.lua` will be automatically merged in the main plugin spec

For a real-life example, you can check [LazyVim](https://github.com/LazyVim/LazyVim) and more specifically:

- [lazyvim.plugins](https://github.com/LazyVim/LazyVim/tree/main/lua/lazyvim/plugins) contains all the plugin specs that will be loaded

### ↩️ Importing Specs, `config` & `opts`

As part of a spec, you can add `import` statements to import additional plugin modules.
Both of the `setup()` calls are equivalent:

```lua
require("lazy").setup("plugins")

-- Same as:
require("lazy").setup({{import = "plugins"}})
```

To import multiple modules from a plugin, add additional specs for each import.
For example, to import LazyVim core plugins and an optional plugin:

```lua
require("lazy").setup({
  spec = {
    { "LazyVim/LazyVim", import = "lazyvim.plugins" },
    { import = "lazyvim.plugins.extras.coding.copilot" },
  }
})
```

When you import specs, you can override them by simply adding a spec for the same plugin to your local
specs, adding any keys you want to override / merge.

`opts`, `dependencies`, `cmd`, `event`, `ft` and `keys` are always merged with the parent spec.
Any other property will override the property from the parent spec.

## ❌ Uninstalling

To uninstall **lazy.nvim**, you need to remove the following files and directories:

- **data**: `~/.local/share/nvim/lazy`
- **state**: `~/.local/state/nvim/lazy`
- **lockfile**: `~/.config/nvim/lazy-lock.json`

> Paths can differ if you changed `XDG` environment variables.
