我无法在 macvim 中折叠我的代码

我的环境和设置位于要点链接 https://gist.github.com/poc7667/7035979

您的 .vimrc 实际上并未在任何地方启用折叠。默认情况下不启用折叠。你需要告诉 Vim 使用什么方法来折叠你的代码。

您使用的方法可能取决于您正在编辑的代码类型。一些语法突出显示文件定义基于语法的折叠。其他语法文件则没有。如果您的代码类型支持基于语法的折叠，那么您可以在加载文件后 :setlocal Foldmethod=syntax 。如果您愿意，您可以在 .vimrc 中的 autocmd 中执行此操作，例如 autocmd FileType c setlocal Foldmethod=syntax 或者您也可以手动执行此操作。

其他自动折叠方法包括“marker”、“expr”和“indent”。默认情况下，折叠方法是“手动”，您必须首先使用 zf 创建折叠才能使用折叠命令。
