设置.emacs中的默认目录

Question

我真的不知道该说些什么。

我一直在努力自定义我的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在Home Directory（~/）中查看初始化文件。。

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，评估了挂钩等。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")，并且可以正常工作。

我猜这个问题可以总结：如果load命令在手动执行时按预期工作，为什么它不自动在启动上工作？

默认目录是buffer local。您的.emacs加载正好；为您打开的每个新缓冲区设置默认目录的值。重新加载.emacs时，它更改了您仅在的缓冲区的默认目录的值。
