我正在编写一个 sml 程序（一种奇怪的函数式编程语言），并且正在警告我的.vimrc文件。但是，我的更改似乎没有对我的文件生效。我可以进行更改.vimrc，然后转到我的 sml 文件并键入 ( gg =G) 以尝试格式化，但更改似乎没有生效。例如，我尝试使用以下几行更改缩进的大小：
set tabstop=150
set shiftwidth=150
set expandtab
我正在尝试设置文本宽度set textwidth=20（20 只是一个测试数字）。
为什么我的.vimrc文件不起作用？我相信它在正确的位置（我的~ directory）。
这是我的全部.vimrc文件，供您参考。

答案1
您需要重新加载~/.vimrc以使更改生效。操作如下：
:source ~/.vimrc
但是，一般来说，在使用设置时，最好在命令行上进行操作，因为它们会立即生效并覆盖文件类型插件的设置：
:set option=value
~/.vimrc当它们满足您的需求时，您可以将它们添加到您的。

为什么要将 tabstop 和 shiftwidth 设置为 150？这似乎不太可能是您想要的。尝试:set在 vim 中以正常模式自行执行，看看 .vimrc 中的值是否正在加载。您还可以执行:echo $MYVIMRC此操作以确保 vim 在正确的位置查找。= 采取的操作取决于或是什么equalprg，indentexpr它可能被加载的 sml 特定 vim 设置所更改filetype plugin indent on。
