如何清除Emacs缓冲区历史记录? [英] How to clear the Emacs buffer history?

问题描述

当我按下 C-x b ( ido-switch-buffer )时，我得到了很多不想看到的缓冲区.我想清除缓冲区历史记录.

When I press C-x b (ido-switch-buffer) I get a lot of buffers that I don't want to see. I'd like to clear the buffer history.

我尝试评估此表达式(使用 M-x eval-buffer ):

I tried evaluating this expression (using M-x eval-buffer):

(setq ido-buffer-history '())

它生效了；我可以说是因为我用 C-h v ido-buffer-history 看了变量.但是，当我按 C-x b 时，更改没有反映在迷你缓冲区中.

And it took effect; I can tell because I looked at the variable with C-h v ido-buffer-history. However, the change did not get reflected in the minibuffer when I press C-x b.

我还应该做什么?我还需要清除其他变量吗?

What else should I do? Are there other variables I should be clearing?

更新:我看到的额外"缓冲区未激活.有趣的是， C-x C-b ( ido-fallback-command )准确地显示了我的期望.这是我感兴趣的缓冲区历史记录.(有关更多上下文，请参见 buffer-name-history 和 ido-buffer-history 变量.)

UPDATE : The 'extra' buffers that I'm seeing are not active. Interestingly, C-x C-b (ido-fallback-command) shows exactly what I would expect. It is the buffer history that I'm interested in. (See the buffer-name-history and ido-buffer-history variables for more context.)

注意:也许会有助于提及我使用的是安装了 ido-ubiquitous 的emacs-starter-kit.

Note: Perhaps it will help to mention that I'm using the emacs-starter-kit which has ido-ubiquitous installed.

推荐答案

在init.el中添加以下内容:(setq ido-use-virtual-buffers nil)

Add the following to your init.el: (setq ido-use-virtual-buffers nil)

后代:

这些都是会话中所有活动的缓冲区.您可以使用以下命令来清理它们:

Those are all the active buffers in your session. You can clean them with the following commands:

• M-x clean-buffer-list 将关闭您一段时间未使用的所有干净缓冲区
• M-x kill-some-buffers 将访问每个缓冲区并询问是否要关闭它
• M-x kill-matching-buffers 将提示输入有关缓冲区名称的正则表达式，您可以将其保留为空白

• M-x clean-buffer-list will close any clean buffers you haven't used in a while
• M-x kill-some-buffers will visit each buffer and ask if you want to close it
• M-x kill-matching-buffers will prompt for a regex over buffer names, which you can just leave blank

您还可以通过 C-x C-b 获得无聊的旧缓冲区菜单.在此菜单中，可以按住 d 直到将每个缓冲区标记为要删除，然后按 x 进行提交.

There's also the boring old buffer menu you get with C-x C-b. In this menu, you can hold d until it marks each buffer for deletion, then press x to commit.
