# deoplete.nvim
> Dark powered asynchronous completion framework for neovim/Vim8
[](https://travis-ci.org/Shougo/deoplete.nvim)
[](https://gitter.im/Shougo/deoplete.nvim?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
[](doc/deoplete.txt)
Note: If you need to understand what's different between deoplete and other
similar plugins, please read "deoplete-faq" section in the documentation.
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.
<!-- vim-markdown-toc GFM -->
- [Install](#install)
- [Requirements](#requirements)
- [Configuration](#configuration)
- [Screenshots](#screenshots)
<!-- vim-markdown-toc -->
## Install
**Note:** deoplete requires Neovim (0.3.0+ and of course, **latest** is
recommended) or Vim8.1 with Python 3.6.1+ and timers enabled. See
[requirements](#requirements) if you aren't sure whether you have this.
Note: deoplete requires msgpack package 1.0.0+.
Please install/upgrade msgpack package by pip.
https://github.com/msgpack/msgpack-python
Note: If you really need to use older msgpack, please use deoplete ver.5.2
instead.
https://github.com/Shougo/deoplete.nvim/releases/tag/5.2
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:
python3 -m pip install --user pynvim
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 pynvim ver.0.3.0+.**
You need update pynvim module.
pip3 install --user --upgrade pynvim
If you want to read the Neovim-python/python3 interface install documentation,
you should read `:help provider-python` and the Wiki.
<https://github.com/deoplete-plugins/deoplete-jedi/wiki/Setting-up-Python-for-Neovim>
## Configuration
```vim
" Use deoplete.
let g:deoplete#enable_at_startup = 1
```
See `:help deoplete-options` for a complete list of options.
