How do you automatically remove the preview window after autocompletion in Vim?
VimAutocompletePreviewVim Problem Overview
I'm using omnifunc=pythoncomplete. When autocompleting a word (e.g., os.<something>), I get the list of eligible class members and functions, as expected, as well as a scratch buffer preview window with documentation about the selected member or function. This is great, but after selecting the function I want, the preview window remains.
I can get rid of it with :pc, but I'd like it just to automatically disappear after I've selected my function, a la Eclipse. I've played around with completeopt but to no avail.
Vim Solutions
Solution 1 - Vim
Put the following in your vimrc:
" If you prefer the Omni-Completion tip window to close when a selection is
" made, these lines close it on movement in insert mode or when leaving
" insert mode
autocmd CursorMovedI * if pumvisible() == 0|pclose|endif
autocmd InsertLeave * if pumvisible() == 0|pclose|endif
Solution 2 - Vim
Even though there is already an accepted answer I found this directly from the docs which will work for any plugin that is having this issue.
autocmd CompleteDone * pclose
Solution 3 - Vim
If you have the supertab plugin installed, there is an option called supertab-closepreviewonpopupclose.
Put the following in your .vimrc:
let g:SuperTabClosePreviewOnPopupClose = 1
Solution 4 - Vim
I don't know how to close it automatically, but you can type
> :pclose
to close the scratch preview manually.
Solution 5 - Vim
You could throw in the following mappings to have certain keys try to close the preview window.
inoremap <space> <C-O>:wincmd z<CR><space>
inoremap ( <C-O>:wincmd z<CR>(
inoremap ) <C-O>:wincmd z<CR>)
inoremap , <C-O>:wincmd z<CR>,
inoremap <CR> <C-O>:wincmd z<CR><CR>
inoremap <esc> <esc>:wincmd z<CR>
You could also use autocommands to close the preview window when you're finished in insert mode:
augroup GoAwayPreviewWindow
autocmd! InsertLeave * wincmd z
augroup end

I know this question is very old, but after days of looking for a "clean" solution I just found the CompleteDone autofunction that does the job:
au CompleteDone * pclose
Solution 7 - Vim
You can type that in the .vimrc:
set completeopt-=preview
