Emacs全局配置选项卡 [英] Emacs global configuration of tabs

问题描述

我试图从Vim切换到Emacs，但我正在撕裂我的头发，试图配置它来处理我想要的标签。我需要：

I'm attempting to switch from Vim to Emacs, but I'm tearing my hair out trying to configure it to treat tabs how I wish. I require:

• 插入标签以扩展为两个空格。 Emacs固执地坚持八个，不管我做了什么。


• 在屏幕上显示标签（即真实 \t 字符） 两个空格。


• 按TAB应该在光标中插入一个标签，而不是缩进整行。目前，我在任何地方按TAB，Emacs在该行开始时销毁所有的空格;这是迄今为止最令人激动的事情。

• Inserted "tabs" to be expanded into two spaces. Emacs stubbornly sticks to eight, no matter what I do.
• Tabs (i.e. real \t characters) to be represented on screen by two spaces.
• Pressing TAB should insert a tab at the cursor rather than indent the entire line. Currently, I press TAB anywhere and Emacs destroys all whitespace at the start of the line; this is the most infuriating thing so far.

我目前的〜/ .emacs 读取

(setq standard-indent 2)
(setq-default indent-tabs-mode nil)

但是我没有尝试从网络结束建议的配置，没有一个完成他们说的话。 （API是否不断变化，我正在使用 GNU Emacs 23.1.1 ，显然。）

but I have tried no end of suggested configurations from the web, none of which have done what they said they would. (Does the API constantly change? I'm using GNU Emacs 23.1.1, apparently.)

推荐答案

Emacs非常灵活地支持处理缩进。一般来说，您所处的模式决定了它们的工作方式 - 所以如果您正在使用C文件，那么按Tab键的方式将与使用Python文件的方式不同。

Emacs has extremely flexible support for handling indentation. Generally the mode that you are in dictates how they work - so if you're working on a C file then the way that pressing tab works will be different than if you're working on a Python file.

所以它确实取决于你正在工作的模式，这将限制你得到的答案。在大多数情况下，我建议您不要与之对抗 - 对我来说，缩进行为是emacs最好的功能之一。但是，您需要花时间为自己定制。

So it does depend which mode you're working in, which will limit the answers you get. In most cases I would recommend that you don't fight against it - for me the indentation behaviour is one of the best features of emacs. However, you do need to spend the time to customize it for yourself.

要更改选项卡的显示方式，您需要将tab-width设置为2.如果编辑Java或C样式代码，那么听起来你想关闭所有这些漂亮的缩进功能到NIL：

To change the way that tabs are displayed you need to set tab-width to 2. If you're editing Java or C style code then it sounds like you want to turn off all the nice indentation features by these to NIL:

• c tab-always-indent


• c语法缩进


• indent-tabs-mode

我建议您通过自定义界面进行设置。如果您使用Mx自定义组RET C，则可以看到C模式的各种设置。

I suggest you set these through the customization interface. If you use "M-x customize-group RET C" then you can see the various settings for C mode.

如果您正在编辑不同类型的文件，那么说明将不同的。

If you're editting different types of files then the instructions will be different.

也许emacs的文件模式是错误的。您可以尝试使用M-x基本模式来查看您是否喜欢该行为。

Perhaps emacs is in the wrong mode for your file. You could try doing "M-x fundamental-mode" to see if you prefer the behaviour there.
