Deoplete is the abbreviation of "dark powered neo-completion".  It
provides an extensible and asynchronous completion framework for
neovim/Vim8.

deoplete will display completions via `complete()` by default.

Here are some [completion sources](https://github.com/Shougo/deoplete.nvim/wiki/Completion-Sources) specifically made for deoplete.nvim.

## Install

**Note:** deoplete requires Neovim (0.2.0+ and of course, **latest** is
recommended) or Vim8 with Python3 and timers enabled.  See
[requirements](#requirements) if you aren't sure whether you have this.

For vim-plug

```viml
if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
let g:deoplete#enable_at_startup = 1
```

For dein.vim

```viml
call dein#add('Shougo/deoplete.nvim')
if !has('nvim')
  call dein#add('roxma/nvim-yarp')
  call dein#add('roxma/vim-hug-neovim-rpc')
endif
let g:deoplete#enable_at_startup = 1
```

For manual installation(not recommended)

1. Extract the files and put them in your Neovim or .vim directory
   (usually `$XDG_CONFIG_HOME/nvim/`).

2. Write `call deoplete#enable()` or `let g:deoplete#enable_at_startup = 1` in
   your `init.vim`

### Requirements

deoplete requires Neovim or Vim8 with `if_python3`.

If `:echo has("python3")` returns `1`, then you have python 3 support; otherwise, see below.

You can enable Python3 interface with pip:

    pip3 install neovim

Please install nvim-yarp and vim-hug-neovim-rpc for Vim8.

- <https://github.com/roxma/nvim-yarp>
- <https://github.com/roxma/vim-hug-neovim-rpc>

**Note: Python3 must be enabled before updating remote plugins**

If Deoplete was installed prior to Python support being added to Neovim,
`:UpdateRemotePlugins` should be executed manually in order to enable
auto-completion.

**Note: deoplete needs neovim-python ver.0.2.4+.**

You need update neovim-python module.

    pip3 install --upgrade neovim

If you want to read the Neovim-python/python3 interface install documentation,
you should read `:help provider-python` and the Wiki.

## Configuration

```vim
" Use deoplete.
let g:deoplete#enable_at_startup = 1
```
