如果您使用的是VIM版本8+，只需键入Ctrl + n或Ctrl + p。

在插入模式下，使用Ctrl-N获取单词建议列表。键入:help i_CTRL-N以查看Vim关于此功能的文档。

下面是一个将Python字典导入Vim的示例。

还有https://github.com/Valloric/YouCompleteMe，它包括像Jedi这样的东西，也有模糊匹配。到目前为止，我发现YCM是我尝试过的最快的。

编辑:也有一些新的网站，如https://github.com/maralla/completor.vim

I recently discovered a project called OniVim, which is an electron-based front-end for NeoVim that comes with very nice autocomplete for several languages out of the box, and since it's basically just a wrapper around NeoVim, you have the full power of vim at your disposal if the GUI doesn't meet your needs. It's still in early development, but it is rapidly improving and there is a really active community around it. I have been using vim for over 10 years and started giving Oni a test drive a few weeks ago, and while it does have some bugs here and there it hasn't gotten in my way. I would strongly recommend it to new vim users who are still getting their vim-fingers!

另一个选项是coc.nvim。

它真的很快，补全很棒，因为它使用了与VScode相同的自动补全功能。 它还具有检测功能。这说明你可能有bug。 它支持多种语言。

它可能需要一些设置和配置，但我认为它是vim最好的自动补全引擎。

您可以从内置的omniunc设置开始。

把:

filetype plugin on
au FileType php setl ofu=phpcomplete#CompletePHP
au FileType ruby,eruby setl ofu=rubycomplete#Complete
au FileType html,xhtml setl ofu=htmlcomplete#CompleteTags
au FileType c setl ofu=ccomplete#CompleteCpp
au FileType css setl ofu=csscomplete#CompleteCSS

在你的。vimrc底部，然后在插入模式下键入<Ctrl-X><Ctrl-O>。

我总是依赖这个CSS完成。
