在 emacs 中设置 auto-mode-alist [英] Setting auto-mode-alist in emacs

问题描述

我注意到当前的自动模式列表条目都以单引号结尾，例如

I notice that the current auto-mode-alist entries all end with a single quote, for example

 ("\.java\'" . java-mode)

单引号的目的是什么.我本来希望看到

What is the purpose of the single quote. I would have expected to see

 ("\.java$" . java-mode)

我问的原因是我试图获取名称与正则表达式匹配的文件

The reason I ask is that I am trying to get files with names matching regexp

^twiki.corp.* 

以组织模式打开.我尝试了以下但没有成功:

to open in org-mode. I have tried the following without success:

(add-to-list 'auto-mode-alist '("^twiki\.corp" . org-mode))
(add-to-list 'auto-mode-alist '("\'twiki\.corp" . org-mode))

以下工作:

(add-to-list 'auto-mode-alist '("twiki\.corp" . org-mode))

但不是我想要的，因为嵌入了 twiki.corp 的文件名将在组织模式下打开.

but is not quite what I want since file names with twiki.corp embedded in them will be opened in org-mode.

推荐答案

\' 匹配字符串/缓冲区末尾的空字符串:

\' matches the empty string at the end of the string/buffer:

http://www.gnu.org/软件/emacs/manual/html_node/emacs/Regexp-Backslash.html el

$ 将匹配行尾:如果文件名中有换行符(非常不常见)，$ 将匹配换行符而不是字符串的结尾.

$ will match the end of the line: If you have newlines in your filename (very uncommon) $ will match the newline and not the end of the string.

正则表达式与整个文件名匹配，因此您需要包含/"以匹配目录分隔符:

The regex is matched against the whole filename, so you need include "/" to match the directory seperator:

(add-to-list 'auto-mode-alist '("/twiki\.corp" . org-mode))
