  [+ruby](https://github.com/junegunn/vim-plug/wiki/ruby) or
  [Neovim](http://neovim.org/))
- On-demand loading to achieve
  [fast startup time](http://junegunn.kr/images/vim-startup-time.png)
- Post-update hooks
- Can choose a specific branch or tag for each plugin
- Support for externally managed plugins

### Usage

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

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

Edit your .vimrc

```vim
call plug#begin('~/.vim/plugged')

" Make sure you use single quotes
Plug 'junegunn/seoul256.vim'
Plug 'junegunn/vim-easy-align'

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

" Using git URL
Plug 'https://github.com/junegunn/vim-github-dashboard.git'

" Plugin options
Plug 'nsf/gocode', { 'tag': 'go.weekly.2012-03-13', 'rtp': 'vim' }

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

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

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' }
```

`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 'Valloric/YouCompleteMe', { 'do': './install.sh' }
```

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.sh
  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 }
```
