如何让Dired忽略具有特定扩展名的文件 [英] How to get Dired to ignore files with specific extensions

问题描述

我将以下内容放在我的.emacs文件中：

I put the following in my .emacs file:

(require 'dired-x)
(add-hook 'dired-load-hook '(lambda () (require 'dired-x)))
(setq dired-omit-files-p t)
(setq dired-omit-files
(concat dired-omit-files "\\|^\\..+$\\|-t\\.tex$\\|-t\\.pdf$"))

但是 Cx d 仍然显示我.pdf和.tex文件。在最后一行我有错误的语法吗？

But C-x d still shows me .pdf and .tex files. Did I get the syntax wrong in that last line?

奖金问题：有没有办法让Dired隐藏隐藏的目录，如.git文件夹？

Bonus question: Is there a way to get Dired to hide hidden directories, like .git folders?

推荐答案

您的正则表达式将匹配 * - t.tex 文件，而不是 *。tex 一个。

Your regexp will match *-t.tex files, not *.tex ones.

使用最新版本的Emacs，将以下部分添加到〜/ .emacs 过滤你想要的东西：

With recent version of Emacs, it should be sufficient to add the following section to ~/.emacs to filter what you want:

(require 'dired-x)
(setq-default dired-omit-files-p t) ; this is buffer-local variable
(setq dired-omit-files
    (concat dired-omit-files "\\|^\\..+$\\|\\.pdf$\\|\\.tex$"))

更新：默认情况下， dired-omit-files regexp过滤掉特殊目录。和。 。如果你不想要这个行为，你可以覆盖默认值（而不是用 concat 继承它们）：

Update: by default, dired-omit-files regexp filters out special directories . and ... If you don't want this behavior, you can just override defaults (instead of inheriting them with concat):

(setq dired-omit-files "^\\.[^.]\\|\\.pdf$\\|\\.tex$")

正则表达式 ^ \\。[^。] 将匹配任何长度为2+的字符串，起始于点，其中第二个字符是除了本身之外的任何字符。这不是完美的（不会匹配文件名，如.. foo），但大部分时间都应该可以。

The regexp ^\\.[^.] will match any string of length 2+ starting with a dot where second character is any character except the dot itself. It's not perfect (will not match filenames like "..foo"), but should be ok most of the time.
