A plugin for deoplete to get abook autocompletion functionality.
This plugin was created by looking at the implementation of deoplete-flow.
Currently only tested with NeoVim and Python3 client. Check out the deoplete documentation to get the basic setup.
Install this plugin with your favourite plugin manager. With dein you can do this:
call dein#add('frbor/deoplete-abook', {'on_ft': "mail"})
Also make sure abook is available as it will use this command for auto completion:
abook --mutt-query
# Binary path to your abook, defaults to your $PATH abook
let g:deoplete#sources#abook#abook_bin = 'abook'
