一、YouCompleteMe

号称Vim中最好的

自动补全插件

，大名鼎鼎的YCM，不需多说。

只是最新版的YCM需要Linux中的gcc和g++支持C++17，且需要Vim版本为8.2.0及以上，需升级一下。

补全效果如下：

二、NERDTree

目录树插件，可以在Vim中直接看到

目录

，并打开

选中的文件

，效果如下图中的

左边栏

：

三、 highlight

语法高亮插件，可以使

STL中的类型名等

高亮，如string的效果如下（但貌似不能使

自己写的类

高亮）：

四、vim-airline, vim-airline-themes，powerline-fonts


vim-airline

用于在Vim中美化

上下标签栏

（如下图中的

绿色

标签）；但美化的主题需要通过

vim-airline-themes

下载；同时，想用如下图所示的小箭头标志的话，还要下载

powerline-fonts

以提供箭头字符的支持。最终效果如下：

上下绿色的标签就是vim-airline的作用了。如果用

NERDTree

打开多个标签，那么Vim的上边栏将是这个样子：

五、Vim更换主题

这个其实就不是插件了

。只要到github把喜欢的主题文件下载下来，把其中的颜色配置文件

xxx.vim

拷贝到

~/.vim/colors

文件夹中，然后在

~/.vimrc

中加入一行命令：

"xxx为颜色配置文件`xxx.vim`中的xxx"
colorscheme xxx 

就可以了。

如我用的

janah

主题颜色如下：

注：上面提到的所有Vim插件不止要下载，还要在

~/.vimrc

中配置一些选项。因此在这里附上我的

~/.vimrc

配置文件供大家参考：
