                                                                     *plug-pros*

 - Easier to setup: Single file. No boilerplate code required.
 - Easier to use: Concise, intuitive syntax
 - {Super-fast}{1} parallel installation/update (with any of `+job`, `+python`,
   `+python3`, `+ruby`, or {Neovim}{2})
 - Creates shallow clones to minimize disk space usage and download time
 - On-demand loading for {faster startup time}{3}
 - Can review and rollback updates
 - Branch/tag/commit support
 - Post-update hooks
 - Support for externally managed plugins

Vim~

You can automate the process by putting the command in your Vim configuration
file as suggested {here}{5}.

< Usage >_____________________________________________________________________~
                                                                    *plug-usage*

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

                                                           *plug#begin* *plug#end*

 1. Begin the section with `call plug#begin()`
 2. List the plugins with `Plug` commands
 3. `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~
                                                                  *plug-example*
>
    " Specify a directory for plugins
    " - For Neovim: ~/.local/share/nvim/plugged
    " - Avoid using standard Vim directory names like 'plugin'
    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-default 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()

< Example: A small sensible Vim configuration >_______________________________~

    call plug#begin()

    call plug#end()
<

< On-demand loading of plugins >______________________________________________~
                                             *plug-on-demand-loading-of-plugins*
>
    " 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 >_________________________________________________________~
                                                        *plug-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.
>
    Plug 'Shougo/vimproc.vim', { 'do': 'make' }
    Plug 'ycm-core/YouCompleteMe', { 'do': './install.py' }
<
If the value starts with `:`, it will be recognized as a Vim command.

                                                            *:GoInstallBinaries*
>
    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.
>
    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 'ycm-core/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.
>
    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:

                                                                 *g:fzf_install*
>
    let g:fzf_install = 'yes | ./install'
    Plug 'junegunn/fzf', { 'do': g:fzf_install }
<

< PlugInstall! and PlugUpdate! >______________________________________________~
                                                    *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.
