< Usage >_____________________________________________________________________~
                                                                    *plug-usage*

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

                                                           *plug#begin* *plug#end*

 1. Begin the section with `call plug#begin([PLUGIN_DIR])`
 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.
 4. Reload the file or restart Vim and run `:PlugInstall` to install plugins.


Example~
                                                                  *plug-example*
>
    call plug#begin()
    " The default plugin directory will be as follows:
    "   - Vim (Linux/macOS): '~/.vim/plugged'
    "   - Vim (Windows): '~/vimfiles/plugged'
    "   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
    " You can specify a custom plugin directory by passing it as the argument
    "   - e.g. `call plug#begin('~/.vim/plugged')`
    "   - Avoid using standard Vim directory names like 'plugin'

    " Make sure you use single quotes

    " Shorthand notation for GitHub; translates to https://github.com/junegunn/vim-easy-align
    Plug 'junegunn/vim-easy-align'

    " Any valid git URL is allowed
    Plug 'https://github.com/junegunn/seoul256.vim.git'

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

    " Using a non-default branch
    Plug 'neoclide/coc.nvim', { 'branch': 'release' }

    " Use 'dir' option to install plugin in a non-default directory
    Plug 'junegunn/fzf', { 'dir': '~/.fzf' }

    " Post-update hook: run a shell command after installing or updating the plugin
    Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }

    " Post-update hook can be a lambda expression
    Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

    " If the vim plugin is in a subdirectory, use 'rtp' option to specify its path
    Plug 'nsf/gocode', { 'rtp': 'vim' }

    " On-demand loading: loaded when the specified command is executed
    Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }

    " On-demand loading: loaded when a file with a specific file type is opened
    Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

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

    " Initialize plugin system
    " - Automatically executes `filetype plugin indent on` and `syntax enable`.
    call plug#end()
    " You can revert the settings after the call like so:
    "   filetype indent off   " Disable file-type-specific indentation
    "   syntax off            " Disable syntax highlighting

Example (Lua configuration for Neovim)~
                                     *plug-example-lua-configuration-for-neovim*

In Neovim, you can write your configuration in a Lua script file named
`init.lua`. The following code is the Lua script equivalent to the VimScript
example above.

    local vim = vim
    local Plug = vim.fn['plug#']

    vim.call('plug#begin')

 - `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`

< Example: A small sensible Vim configuration >_______________________________~
                               *plug-example-a-small-sensible-vim-configuration*
>
    call plug#begin()
    Plug 'tpope/vim-sensible'
    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 'preservim/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!'
<
The `for` option is generally not needed as most plugins for specific file
types usually don't have too much code in the `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 the `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.
>
    Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
<
To call a Vim function, you can pass a lambda expression like so:
>
    Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
<
If you need more control, you can pass a reference to a Vim function that
takes a dictionary 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') }
<
A post-update hook is 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 the `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 the `!` suffix ensure that all steps are run
unconditionally.
