**lazy.nvim** is a modern plugin manager for Neovim.
![image](https://user-images.githubusercontent.com/292349/207705153-077e183e-ae5f-4cbe-b1d8-07b7bf86026e.png)
## ✨ 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
- 📚 Generates helptags of the headings in `README.md` files for plugins that don't have vimdocs
- 💻 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** (needs to be built with **LuaJIT**)
- Built for **Linux** and **MacOS**
- Git >= **2.19.0** (for partial clones support)
## 📦 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",
"git@github.com:folke/lazy.nvim.git",
lazypath,
})
end
vim.opt.runtimepath:prepend(lazypath)
```
<!-- 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 |
| ---------------- | ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `[1]` | `string?` | Short plugin url. Will be expanded using `config.git.url_format` |
| **dir** | `string?` | A directory pointing to a local plugin |
| **url** | `string?` | A custom git url where the plugin is hosted |
| **name** | `string?` | A custom name for the plugin used for the local plugin directory and as the dispay name |
| **dev** | `boolean?` | When `true`, a local plugin directory will be used instead. See `config.dev` |
| **lazy** | `boolean?` | When `true`, the plugin will only be loaded when needed. Lazy-loaded plugins are automatically loaded when their lua modules are `required`, or when one of the laz-loading handlers triggers |
| **enabled** | `boolean?` or `fun():boolean` | When `false`, or if the `function` returns false, then this plugin will not be used |

| **init** | `fun(LazyPlugin)` | `init` functions are always executed during startup |
| **config** | `fun(LazyPlugin)` | `config` is executed when the plugin loads |
| **build** | `fun(LazyPlugin)` | `build` is executed when a plugin is installed or updated |
| **branch** | `string?` | Branch of the repository |
| **tag** | `string?` | Tag of the repository |

| **version** | `string?` | Version to use from the repository. Full [Semver](https://devhints.io/semver) ranges are supported |
| **pin** | `boolean?` | When `true`, this plugin will not be included in updates |
| **event** | `string?` or `string[]` | Lazy-load on event |

## ⚙️ 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

disabled_plugins = {
-- "gzip",
-- "matchit",
-- "matchparen",
-- "netrwPlugin",
-- "tarPlugin",
-- "tohtml",
-- "tutor",
-- "zipPlugin",
},
},
},
-- lazy can generate helptags from the headings in markdown readme files,
-- so :help works even for plugins that don't have vim docs.
-- when the readme opens with :help it will be correctly displayed as markdown
readme = {
root = vim.fn.stdpath("state") .. "/lazy/readme",
files = { "README.md" },
-- only generate markdown helptags for plugins that dont have docs
skip_if_doc_exists = true,
},
}
```

## 🚀 Usage
You can manage all your plugins with the main `:Lazy` command.
Alternatively you can start any operation with a specific command, sub command or API function:

## ▶️ 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 files from `/plugin` and `/ftdetect` directories in you rtp are sourced (excluding `/after`)
2. all plugins with `lazy=false` are loaded. This includes sourcing `/plugin` and `/ftdetect` files. (`/after` will not be sourced yet)
3. all plugins' `/after/plugin` files are sourced
4. all `/after/plugin` files from the original rtp are sourced
5. all the plugins' `init()` functions are executed
Files from runtime directories are always sourced in alphabetical order.
## 📦 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
