==============================================================================
INTRODUCTION *defx-introduction*
*defx* is the abbreviation of "dark powered file explorer".
==============================================================================
INSTALL *defx-install*
Note: defx requires Neovim 0.4.0+ or Vim8.2+ with Python3.6.1+.
Note: The latest Neovim is recommended, because it is faster.
Please install nvim-yarp plugin for Vim8.
https://github.com/roxma/nvim-yarp
Please install vim-hug-neovim-rpc plugin for Vim8.
https://github.com/roxma/vim-hug-neovim-rpc
1. Extract the files and put them in your Neovim or .vim directory
(usually `$XDG_CONFIG_HOME/nvim/`).
2. Execute the ":UpdateRemotePlugins" if Neovim.
If ":echo has('python3')" returns `1`, then you're done; otherwise, see below.
You can enable Python3 interface with pip: >
pip3 install --user pynvim
Note: defx needs pynvim ver.0.1.8+. You need update pynvim module.
>
pip3 install --user --upgrade pynvim
<
If you want to read for pynvim/python3 interface install documentation,
you should read |provider-python| and the Wiki.
https://github.com/zchee/deoplete-jedi/wiki/Setting-up-Python-for-Neovim
You can check the Python3 installation by |:checkhealth| command in neovim.
