  (with any of `+job`, `+python`, `+python3`, `+ruby`, or [Neovim][nv])
- Creates shallow clones to minimize disk space usage and download time
- On-demand loading for [faster startup time][startup-time]
- Can review and rollback updates
- Branch/tag/commit support
- Post-update hooks
- Support for externally managed plugins

### Installation

[Download plug.vim](https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim)
and put it in the "autoload" directory.

###### Unix

```sh
curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

###### Neovim

```sh
curl -fLo ~/.local/share/nvim/site/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

###### Windows (PowerShell)

```powershell
md ~\vimfiles\autoload
$uri = 'https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
(New-Object Net.WebClient).DownloadFile($uri, $ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath("~\vimfiles\autoload\plug.vim"))

### Usage

Add a vim-plug section to your `~/.vimrc` (or `~/.config/nvim/init.vim` for Neovim):

1. Begin the section with `call plug#begin()`
1. List the plugins with `Plug` commands
1. `call plug#end()` to update `&runtimepath` and initialize plugin system
    - Automatically executes `filetype plugin indent on` and `syntax enable`.
      You can revert the settings after the call. e.g. `filetype indent off`, `syntax off`, etc.

#### Example

```vim
" Specify a directory for plugins (for Neovim: ~/.local/share/nvim/plugged)
call plug#begin('~/.vim/plugged')

" Make sure you use single quotes

" Shorthand notation; fetches https://github.com/junegunn/vim-easy-align
Plug 'junegunn/vim-easy-align'

" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-github-dashboard.git'

" Multiple Plug commands can be written in a single line using | separators
Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'

" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Using a non-master branch
Plug 'rdnetto/YCM-Generator', { 'branch': 'stable' }

" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }

" Plugin options
Plug 'nsf/gocode', { 'tag': 'v.20150303', 'rtp': 'vim' }

" Plugin outside ~/.vim/plugged with post-update hook
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }

" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'

" Initialize plugin system
call plug#end()
```

Reload .vimrc and `:PlugInstall` to install plugins.

### Keybindings

- `D` - `PlugDiff`
- `S` - `PlugStatus`
- `R` - Retry failed update or installation tasks
- `U` - Update plugins in the selected range
- `q` - Close the window
- `:PlugStatus`
    - `L` - Load plugin
- `:PlugDiff`
    - `X` - Revert the update

### Example: A small [sensible](https://github.com/tpope/vim-sensible) Vim configuration

```vim
call plug#begin()
Plug 'tpope/vim-sensible'
call plug#end()
```

### On-demand loading of plugins

```vim
" NERD tree will be loaded on the first invocation of NERDTreeToggle command
Plug 'scrooloose/nerdtree', { 'on': 'NERDTreeToggle' }

" Multiple commands
Plug 'junegunn/vim-github-dashboard', { 'on': ['GHDashboard', 'GHActivity'] }

" Loaded when clojure file is opened
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Multiple file types
Plug 'kovisoft/paredit', { 'for': ['clojure', 'scheme'] }

" On-demand loading on both conditions
Plug 'junegunn/vader.vim',  { 'on': 'Vader', 'for': 'vader' }

" Code to execute when the plugin is lazily loaded on demand
Plug 'junegunn/goyo.vim', { 'for': 'markdown' }
autocmd! User goyo.vim echom 'Goyo is now loaded!'
```

`for` option is generally not needed as most plugins for specific file types
usually don't have too much code in `plugin` directory. You might want to
examine the output of `vim --startuptime` before applying the option.

### Post-update hooks

There are some plugins that require extra steps after installation or update.
In that case, use `do` option to describe the task to be performed.

```vim
Plug 'Shougo/vimproc.vim', { 'do': 'make' }
Plug 'Valloric/YouCompleteMe', { 'do': './install.py' }
```

If the value starts with `:`, it will be recognized as a Vim command.

```vim
Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
```

If you need more control, you can pass a reference to a Vim function that
takes a single argument.

```vim
function! BuildYCM(info)
  " info is a dictionary with 3 fields
  " - name:   name of the plugin
  " - status: 'installed', 'updated', or 'unchanged'
  " - force:  set on PlugInstall! or PlugUpdate!
  if a:info.status == 'installed' || a:info.force
    !./install.py
  endif
endfunction

Plug 'Valloric/YouCompleteMe', { 'do': function('BuildYCM') }
```

Both forms of post-update hook are executed inside the directory of the plugin
and only run when the repository has changed, but you can force it to run
unconditionally with the bang-versions of the commands: `PlugInstall!` and
`PlugUpdate!`.

Make sure to escape BARs and double-quotes when you write `do` option inline
as they are mistakenly recognized as command separator or the start of the
trailing comment.

```vim
Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }
```

But you can avoid the escaping if you extract the inline specification using a
variable (or any Vimscript expression) as follows:

```vim
let g:fzf_install = 'yes | ./install'
Plug 'junegunn/fzf', { 'do': g:fzf_install }
```

### `PlugInstall!` and `PlugUpdate!`

The installer takes the following steps when installing/updating a plugin:

1. `git clone` or `git fetch` from its origin
2. Check out branch, tag, or commit and optionally `git merge` remote branch
3. If the plugin was updated (or installed for the first time)
    1. Update submodules
    2. Execute post-update hooks

The commands with `!` suffix ensure that all steps are run unconditionally.
