REQUIREMENTS *lazy.nvim-lazy.nvim-requirements*
- Neovim >= **0.8.0** (needs to be built with **LuaJIT**)
- Git >= **2.19.0** (for partial clones support)
- a Nerd Font <https://www.nerdfonts.com/> **(optional)**
INSTALLATION *lazy.nvim-lazy.nvim-installation*
You can add the following Lua code to your `init.lua` to bootstrap
**lazy.nvim**
>lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
vim.fn.system({
"git",
"clone",
"--filter=blob:none",
"https://github.com/folke/lazy.nvim.git",
"--branch=stable", -- latest stable release
lazypath,
})
end
vim.opt.rtp:prepend(lazypath)
<
Nextstep is to add **lazy.nvim** below the code added in the prior step in
`init.lua`
>lua
require("lazy").setup(plugins, opts)
<
- **plugins**this should be a `table` or a `string`
- `table`a list with your |lazy.nvim-plugin-spec|
- `string`a Lua module name that contains your |lazy.nvim-plugin-spec|. See |lazy.nvim-structuring-your-plugins|
- **opts**see |lazy.nvim-configuration| **(optional)**
>lua
-- Example using a list of specs with the default options
vim.g.mapleader = " " -- Make sure to set `mapleader` before lazy so your mappings are correct
vim.g.maplocalleader = "\\" -- Same for `maplocalleader`
require("lazy").setup({
"folke/which-key.nvim",
{ "folke/neoconf.nvim", cmd = "Neoconf" },
"folke/neodev.nvim",
})
<
It is recommended to run `:checkhealth lazy` after installation.
PLUGIN SPEC *lazy.nvim-lazy.nvim-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 display 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 lazy-loading handlers triggers
enabled boolean? or fun():boolean When false, or if the function returns false, then
this plugin will not be included in the spec
cond boolean? or fun(LazyPlugin):boolean When false, or if the function returns false, then
this plugin will not be loaded. Useful to disable
some plugins in vscode, or firenvim for example.
dependencies LazySpec[] A list of plugin names or plugin specs that should
be loaded when the plugin loads. Dependencies are
always lazy-loaded unless specified otherwise. When
specifying a name, make sure the plugin spec has
been defined somewhere else.
init fun(LazyPlugin) init functions are always executed during startup
opts table or fun(LazyPlugin, opts:table) opts should be a table (will be merged with parent
specs), return a table (replaces parent specs) or
should change a table. The table will be passed to
the Plugin.config() function. Setting this value
will imply Plugin.config()
config fun(LazyPlugin, opts:table) or true config is executed when the plugin loads. The
default implementation will automatically run
require(MAIN).setup(opts) if opts or config = true
is set. Lazy uses several heuristics to determine
the plugin’s MAIN module automatically based on the
plugin’s name. See also opts. To use the default
implementation without opts set config to true.
main string? You can specify the main module to use for config()
and opts(), in case it can not be determined
automatically. See config()
build fun(LazyPlugin) or string or a list of build commands build is executed when a plugin is installed or
updated. Before running build, a plugin is first
loaded. If it’s a string it will be run as a shell
command. When prefixed with : it is a Neovim
command. You can also specify a list to executed
multiple build commands. Some plugins provide their
own build.lua which is automatically used by lazy.
So no need to specify a build step for those
plugins.
branch string? Branch of the repository
tag string? Tag of the repository
commit string? Commit of the repository
version string? or false to override the default Version to use from the repository. Full Semver
ranges are supported
pin boolean? When true, this plugin will not be included in
updates
submodules boolean? When false, git submodules will not be fetched.
Defaults to true
event string? or string[] or Lazy-load on event. Events can be specified as
fun(self:LazyPlugin, event:string[]):string[] or BufEnter or with a pattern like BufEnter *.lua
{event:string[]\|string, pattern?:string[]\|string}
cmd string? or string[] or Lazy-load on command
fun(self:LazyPlugin, cmd:string[]):string[]
ft string? or string[] or Lazy-load on filetype
fun(self:LazyPlugin, ft:string[]):string[]
keys string? or string[] or LazyKeysSpec[] or Lazy-load on key mapping
fun(self:LazyPlugin, keys:string[]):(string \| LazyKeysSpec)[]
module false? Do not automatically load this Lua module when it’s
required somewhere
priority number? Only useful for start plugins (lazy=false) to force
loading certain plugins first. Default priority is
50. It’s recommended to set this to a high number
for colorschemes.
optional boolean? When a spec is tagged optional, it will only be
included in the final spec, when the same plugin has
been specified at least once somewhere else without
optional. This is mainly useful for Neovim distros,
to allow setting options on plugins that may/may not
be part of the user’s plugins
------------------------------------------------------------------------------------------------------------------------------------
LAZY LOADING ~
**lazy.nvim** automagically lazy-loads Lua modules, so it is not needed to
specify `module=...` everywhere in your plugin specification. This means that
if you have a plugin `A` that is lazy-loaded and a plugin `B` that requires a
module of plugin `A`, then plugin `A` will be loaded on demand as expected.
If you don’t want this behavior for a certain plugin, you can specify that
with `module=false`. You can then manually load the plugin with `:Lazy load
foobar.nvim`.
You can configure **lazy.nvim** to lazy-load all plugins by default with
`config.defaults.lazy = true`.
Additionally, you can also lazy-load on **events**, **commands**, **file
types** and **key mappings**.
Plugins will be lazy-loaded when one of the following is `true`
- Theplugin only exists as a dependency in your spec
- It has an `event`, `cmd`, `ft` or `keys` key
- `config.defaults.lazy == true`
COLORSCHEMES
Colorscheme plugins can be configured with `lazy=true`. The plugin will
automagically load when doing `colorscheme foobar`.
**NOTE:** since **start** plugins can possibly change existing highlight
groups, it’s important to make sure that your main **colorscheme** is loaded
first. To ensure this you can use the `priority=1000` field. **(see the
examples)**
LAZY KEY MAPPINGS
The `keys` property can be a `string` or `string[]` for simple normal-mode
mappings, or it can be a `LazyKeysSpec` table with the following key-value
pairs:
- **[1]**(`string`) lhs **(required)**
- **[2]**(`string|fun()`) rhs **(optional)**
- **mode**(`string|string[]`) mode **(optional, defaults to "n")**
- **ft**(`string|string[]`) `filetype` for buffer-local keymaps **(optional)**
- any other option valid for `vim.keymap.set`
Key mappings will load the plugin the first time they get executed.
When `[2]` is `nil`, then the real mapping has to be created by the `config()`
function.
>lua
-- Example for neo-tree.nvim
{
"nvim-neo-tree/neo-tree.nvim",
keys = {
{ "<leader>ft", "<cmd>Neotree toggle<cr>", desc = "NeoTree" },
},
config = function()
require("neo-tree").setup()
end,
}
<
VERSIONING ~
If you want to install a specific revision of a plugin, you can use `commit`,
`tag`, `branch`, `version`.
The `version` property supports Semver <https://semver.org/> ranges.
Click to see some examples ~
- `*`latest stable version (this excludes pre-release versions)
- `1.2.x`any version that starts with `1.2`, such as `1.2.0`, `1.2.3`, etc.
- `^1.2.3`any version that is compatible with `1.2.3`, such as `1.3.0`, `1.4.5`, etc., but not `2.0.0`.
- `~1.2.3`any version that is compatible with `1.2.3`, such as `1.2.4`, `1.2.5`, but not `1.3.0`.
- `>1.2.3`any version that is greater than `1.2.3`, such as `1.3.0`, `1.4.5`, etc.
- `>=1.2.3`any version that is greater than or equal to `1.2.3`, such as `1.2.3`, `1.3.0`, `1.4.5`, etc.
- `<1.2.3`any version that is less than `1.2.3`, such as `1.1.0`, `1.0.5`, etc.
- `<=1.2.3`any version that is less than or equal to `1.2.3`, such as `1.2.3`, `1.1.0`, `1.0.5`, etc
You can set `config.defaults.version = "*"` to install the latest stable
version of plugins that support Semver.

USAGE *lazy.nvim-lazy.nvim-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:
--------------------------------------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------------------------------------
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()`):
>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 = {},
}
<
**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.
Example of configuring lualine.nvim ~
>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.
LOCKFILE LAZY-LOCK.JSON *lazy.nvim-lazy.nvim-lockfile-lazy-lock.json*
After every **update**, the local lockfile is updated with the installed
revisions. It is recommended to have this file under version control.
If you use your Neovim config on multiple machines, using the lockfile, you can
ensure that the same version of every plugin is installed.
If you are on another machine, you can do `:Lazy restore`, to update all your
plugins to the version from the lockfile.
PERFORMANCE *lazy.nvim-lazy.nvim-performance*
Great care has been taken to make the startup code (`lazy.core`) as efficient
as possible. During startup, all Lua files used before `VimEnter` or
`BufReadPre` are byte-compiled and cached, similar to what impatient.nvim
<https://github.com/lewis6991/impatient.nvim> does.
My config for example loads in about `11ms` with `93` plugins. I do a lot of
lazy-loading though :)
**lazy.nvim** comes with an advanced profiler `:Lazy profile` to help you
improve performance. The profiling view shows you why and how long it took to
load your plugins.
DEBUG *lazy.nvim-lazy.nvim-debug*
See an overview of active lazy-loading handlers and what’s in the module
cache.
STARTUP SEQUENCE *lazy.nvim-lazy.nvim-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| 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 *lazy.nvim-lazy.nvim-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.
MIGRATION GUIDE *lazy.nvim-lazy.nvim-migration-guide*
PACKER.NVIM ~
- `setup` `init`
- `requires` `dependencies`
- `as` `name`
- `opt` `lazy`
- `run` `build`
- `lock` `pin`
- `disable=true` `enabled = false`
- `tag='*'` `version="*"`
- `after` is **not needed** for most use-cases. Use `dependencies` otherwise.
- `wants` is **not needed** for most use-cases. Use `dependencies` otherwise.
- `config` don’t support string type, use `fun(LazyPlugin)` instead.
- `module` is auto-loaded. No need to specify
- `keys` spec is |lazy.nvim-different|
- `rtp` can be accomplished with:
>lua
config = function(plugin)
vim.opt.rtp:append(plugin.dir .. "/custom-rtp")
end
<
With packer `wants`, `requires` and `after` can be used to manage dependencies.
With lazy, this isn’t needed for most of the Lua dependencies. They can be
installed just like normal plugins (even with `lazy=true`) and will be loaded
when other plugins need them. The `dependencies` key can be used to group those
required plugins with the one that requires them. The plugins which are added
as `dependencies` will always be lazy-loaded and loaded when the plugin is
loaded.
PAQ-NVIM ~
- `as` `name`
- `opt` `lazy`
- `run` `build`
UNINSTALLING *lazy.nvim-lazy.nvim-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.

PLUGIN AUTHORS *lazy.nvim-lazy.nvim-plugin-authors*
If your plugin needs a build step, you can create a file `build.lua` or
`build/init.lua` in the root of your repo. This file will be loaded when the
plugin is installed or updated.
This makes it easier for users, as they no longer need to specify a `build`
command.
