Dark powered asynchronous completion framework for neovim/Vim8

Build Status Join the chat at https://gitter.im/Shougo/deoplete.nvim Doc

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 specifically made for deoplete.nvim.

Install

Note: deoplete requires Neovim (0.3.0+ and of course, latest is recommended) or Vim8 with Python 3.6.1+ and timers enabled. See 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

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

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 --user pynvim

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

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

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

See

:help deoplete-options
for a complete list of options.
