如果你只想从当前缓冲区的缓存中自动补全，supertab比neocomplete更容易安装，可以在Mac预装的vim上工作，而不需要MacVim。

你可以在vim awesome上查看其他选择。

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。

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!

你可以使用像AutoComplPop这样的插件在你输入的时候自动完成代码。

2015编辑:我个人现在使用YouCompleteMe。

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

如果您使用的是VIM版本8+，只需键入Ctrl + n或Ctrl + p。
