emacs 配置文件目录

在 windows 环境下，emacs 的配置目录可以通过下面几种方式来设置：

1. If the environment variableHOME is set, use the directory it indicates.
2. If the registry entry HKCU\SOFTWARE\GNU\Emacs\HOME is set, use the directory it indicates.
3. If the registry entry HKLM\SOFTWARE\GNU\Emacs\HOME is set, use the directory it indicates. Not recommended, as it results in users sharing the same HOME directory.
4. If C:.emacs exists, then use C:/. This is for backward compatibility, as previous versions defaulted to C:/ if HOME was not set.
5. Use the user's AppData directory, usually a directory called Application Data under the user's profile directory, the location of which varies according to Windows version and whether the computer is part of a domain.

HOME 是 String 类型的值。

然后运行 bin\runemacs.exe 就可以打开 emacs 了。
