Dark deno powered completion framework for neovim/Vim8

Please read help for details.

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

ddc will display completions via complete() by default.

Introduction

I have chosen denops.vim framework to create new auto completion plugin. Because denops.vim is better than neovim Python interface.

• Easy to setup
• Minimal dependency
• Stability
• neovim/Vim8 compatibility
• Speed
• Library
• Easy to hack

Install

Note: ddc requires Neovim (0.5.0+ and of course, latest is recommended) or Vim8.2. See requirements if you aren't sure whether you have this.

For vim-plug

call plug#begin()

Plug 'Shougo/ddc.vim'
Plug 'vim-denops/denops.vim'

call plug#end()

For dein.vim

call dein#begin()

call dein#add('Shougo/ddc.vim')
call dein#add('vim-denops/denops.vim')

call dein#end()

Requirements

ddc requires both Deno and denops.vim.
