I use omnicomplete in VIM and my vimrc is like below.
snipping...
" Autocompletion
set completeopt=longest,noselect,menuone
set omnifunc=syntaxcomplete#Complete
autocmd FileType py set omnifunc=python3complete#Complete
But, when I restart vim. omnifunc doesn't work as i set, even value is different from my vimrc settings
I thought my restoring option was problem. However, block below settings.
" Save and load former states
"autocmd BufWinLeave ?* mkview
"autocmd BufWinEnter ?* silent loadview
It still doesn't work... How can I resolve it? Appreciate all your help.
