Question

我试图在我的VIM中实现代码折叠。我相信它们的标准命令是za，zc，zo等。据我所知，人们不需要做任何特别的事情来使这些命令发挥作用。我主要是JS程序员。

但是这些命令都不能在我的VIM中运行。我正在使用VIM 7.2

下面是我的.vimrc文件我提出我的整个.vimrc文件的原因是因为我猜可能有一个我正在使用的插件可能导致折叠命令不起作用。

如果有人知道这里有什么不妥之处..请指出。

Answer 1

我相信要使折叠命令起作用，你需要设置foldmethod选项。在我看来，最简单的就是'缩进'。

Answer 2

我用：

vmap <F4> zf
vmap <F5> zd

在我的.vimrc文件中。这允许我使用F4和F5键进行折叠/展开。
