deoplete

Deoplete is the abbreviation of "dark powered neo-completion". It provides an asynchronous keyword completion system in the current buffer. To view the current options, please consult the documentation.

Installation

Note: deoplete requires Neovim(latest is recommended) with Python3 and timers enabled. See requirements if you aren't sure whether you have this.

Extract the files and put them in your Neovim directory (usually $XDG_CONFIG_HOME/nvim/).
Execute the :UpdateRemotePlugins and restart Neovim.
Write call deoplete#enable() or let g:deoplete#enable_at_startup = 1 in your init.vim

For vim-plug

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

For dein.vim

call dein#add('Shougo/deoplete.nvim')

Requirements

deoplete requires Neovim with if_python3. If :echo has("python3") returns 1, then you're done; otherwise, see below.

You can enable Python3 interface with pip:

pip3 install neovim

Note: deoplete needs neovim-python ver.0.1.8+.

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. https://github.com/zchee/deoplete-jedi/wiki/Setting-up-Python-for-Neovim

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.
