Provide a minimal init.vim with less than 50 lines (Required!)

" Your minimal init.vim
set runtimepath+=~/path/to/deoplete.nvim/
let g:deoplete#enable_at_startup = 1

Watch for a comparison between deoplete and mucomplete: https://asciinema.org/a/9gl1mctgceo6vojw28nxq8qf8

First I use deoplete and the pop up does not appear until I stop briefly, whereas with mucomplete, it is instant.

Though, the one problem with mucomplete being so fast is that sometimes, even though the popup has appeared but still flickering and thus not there briefly, I cannot always press <C-N> to cycle through. that seems to be a bug actually, lifepillar/vim-mucomplete#50

that feels so much better, thank you!

nhooyr commented Jan 8, 2017

@Shougo why is it set to such a high value by default?

@Shougo you should add it to the FAQ, I'm sure there are also people who want no delay.
