在 .emacs 中设置默认目录

Question

我真的不知道该说什么。

我一直致力于自定义我的 emacs，我注意到它实际上并没有在启动时加载我的 .emacs。根据（http://www.gnu.org/software/emacs/manual/html_node/emacs/Find-Init.html#Find-Init），emacs首先在HOME目录（~/）中查找初始化文件...

当我启动 emacs 时，我的 .emacs 文件 似乎 可以正确读取 - 例如，当我访问 .notes 文件时，会评估挂钩等等。令我惊讶的是：未设置默认目录 - 同一加载文件中的命令。我可以手动评估它，也可以简单地执行(load "~/.emacs")，它会正常工作。

我想问题可以总结一下：如果手动执行load命令按预期工作，为什么它在启动时不能自动工作？

默认目录是本地缓冲区。你的 .emacs 加载得很好；为您打开的每个新缓冲区（重新）设置默认目录的值。当您重新加载 .emacs 时，它只会更改您所在缓冲区的 default-directory 的值。
