问题描述

如何在 Emacs 中全局或仅对某些模式禁用自动缩进?

How to disable auto indent in Emacs globally or only for some modes?

我为 RubyOnRails 安装了许多软件包(ruby、html、js、css).

I have a number of packages installed for RubyOnRails (ruby, html, js, css).

假设我想为 css 模式禁用自动缩进.

Let's say I want to disable autoindent for css-mode.

推荐答案

您可能想要查找包含单词 electric 的变量名称.(这是 Emacs 的常用说法，用于在键入特定可见字符时自动发生的操作.)

You may want to look for variable names containing the word electric. (This is the common Emacs parlance for actions which occur automatically when particular visible characters are typed.)

在这种情况下，Mx apropos-variable RET electric RET 显示我知道有一个 css-electric-keys 变量包含一个应该触发重新缩进的自插入键"列表.

In this instance, M-x apropos-variable RET electric RET shows me that there is a css-electric-keys variable containing a list of "Self inserting keys which should trigger re-indentation."

你可以使用 Mx customize-variable RET css-electric-keys RET 将此列表设置为 nil，或将 (setq css-electric-keys nil) 添加到您的 init 文件中.

You could use M-x customize-variable RET css-electric-keys RET to set this list to nil, or add (setq css-electric-keys nil) to your init file.

有时会使用次要模式来实现电气行为，以便您可以更轻松地打开和关闭它们.那些很可能通过 Mx apropos-command RET electric RET 找到，和您可能会使用主模式挂钩来确保禁用电动次要模式，方式与此类似:

Sometimes a minor mode is used to implement electric behaviours, so that you can switch them on and off more easily. Those would likely be found via M-x apropos-command RET electric RET, and you would probably use a major mode hook to ensure that the electric minor mode was disabled, in a similar fashion to this:

(add-hook 'MAJORMODE-mode-hook 'my-MAJORMODE-mode-hook)
(defun my-MAJORMODE-mode-hook ()
  (ELECTRICMODE-mode 0))
