Vim 使用 Vexplore 和终端自动启动

我想将 vim 设置为在大多数情况下表现得像传统的 ide。我想做的是，当我输入命令 vim 时，它会以这种方式打开：

Vim 窗口

问题是它是这样打开的：

vim 演示

我希望终端自动启动，但在上一个窗口中。我尝试阅读文档，但我不知道如何阅读文档并将其放入代码中，我的 vimrc 中的大部分代码都是复制粘贴的，还有一些我已经知道的基础知识。我会喜欢让它像第一张图片一样自动启动。

另外，还有一个问题我不确定在 vim 中是否可能，有时在 NetRW 中，当我单击缓冲区时，缓冲区会擦除目录树，然后会出现一个空白缓冲区。是否有办法禁用某些命令干扰终端缓冲区和目录树列表？一个例子是，如果我尝试打开一个文件，并且最后一个缓冲区是终端缓冲区，它会问我是否要保存当前缓冲区（终端）并打开该文件，我希望它能够更智能地在非终端缓冲区而不是终端。除了输入命令之外，基本上完全忽略终端。

这是我的 vimrc，可能很混乱，因为我除了复制和粘贴之外什么也没做：

请改用此自动命令：

autocmd VimEnter *
    \ Vexplore |
    \ execute "wincmd l" |
    \ rightbelow term bash

当您进入 Vim 时，这将执行整个序列一次。我使用续行符（后续行以反斜杠开头）和栏来运行多个命令。另请注意，autocmd运行 Ex 命令，因此前面的命令:并不是真正必要的。

第一个命令将按预期打开左侧的 NERDTree 窗口。

其次，wincmd l将移动到右侧的窗口（参见:help :wincmd）。这是您的尝试中缺少的步骤，这导致下一步分割 NERDTree 而不是主窗口。需要wincmd在 内部运行execute，否则它将尝试解释|其后面的 ，这将停止作为分隔符工作。

最后，最后一个命令打开终端，使用显式rightbelow（请参阅 参考资料:help :rightbelow）来打开底部的分割。就是这样！
