This is a vim fork that enables fuzzy
search on completion candidates by the virtue of slightly modified
fzy. All you need to do is
set completeopt+=fuzzy and trigger completion popup somehow (I personally use
mucomplete plugin for that).
Some time ago I made a similar neovim fork, look
here for more info. But then fixing
neovim bugs became annoying and I decided to give vim a shot again. So here
you go. As usual, I'm not responsible for any damage you can cause or suffer
from during this fork usage.
