如何使Emacs自动缩进我的C代码？ [英] How do I make Emacs auto-indent my C code?

问题描述

我刚刚开始感受到emacs，但是当我按下返回键时，我很失望。我知道如果我按C-j它会做，但我不能陷入这种习惯。可新新旗新新新旗新新旗新新旗新新旗新新旗新新旗旗新新旗新新200新新我需要返回，我讨厌每次重新绑定。

I'm just starting to get a feel for emacs, but I am frustrated with it's tendency to not indent when I press the return key. I know if I press C-j it will do it, but I can't get into that habit. I just can't. I need to hit return, and I hate re-tabbing every time.

我进入选项，发现C模式挂钩，C ++模式挂钩等 - 和他们定义了两个关键字映射（10和13，我记得0A和0D是CR / LF，因为我在组装中使用了很多） - 我认为，因为一个说（lambda nil（define-key lisp-mode-map [13]（引用newline-and-indent）），而另一个相同，但是与（报价换行符）相反我只是把它和缩进结束了，并且认为它会奏效。

I went into the options and found C mode hook, and C++ mode hook, etc--and they defined two keymappings (10 and 13, and I remembered that 0A and 0D are CR/LF because I used them a lot in assembly)--I figured since one said "(lambda nil (define-key lisp-mode-map [13] (quote newline-and-indent))" and the other the same but with (quote newline) instead, I just put the -and-indent at the end of it and figured it would work.

但是它不会：我设置并保存它，尝试，无法重新启动emacs，仍然没有成功我如何使其缩进我的代码？这是非常疯狂的，emacs需要一个学位在lisp只是为了配置它的基本需求。

But it doesn't: I set and saved it, tried, to no avail. Restarted emacs, still no success. How do I make it indent my code? It's terribly insane that emacs requires a degree in lisp just to configure it for your basic needs.

另外，作为一个侧面的问题：我如何复制和粘贴从剪贴板？杀死/打屁股是方便的，除了我讨厌去编辑 - >每次我想要复制粘贴到其他地方。

Also, as a sort of side question: how do I copy to and paste from the clipboard? Killing/yanking is handy and all but I hate going edit->copy every time I want to paste to somewhere else.

- 编辑 -

好的，我将以下行放入我的.emacs，它的工作原理是：

okay, I put the following lines into my .emacs and it worked:

(add-hook 'c-mode-common-hook (lambda ()
      (local-set-key (kbd "RET") 'newline-and-indent)))

感谢您的帮助

推荐答案

查看 emacswiki - autoindent

根据建议，将.emacs中的以下代码

As suggested there, put following code in your .emacs

(defun set-newline-and-indent ()
  (local-set-key (kbd "RET") 'newline-and-indent))
(add-hook 'c-mode 'set-newline-and-indent)

您可以自定义变量C默认样式。在您的emacs中，选择 - >自定义Emacs->特定选项，然后键入c-default-style并设置为您的选择。通过这样做，你不需要打TAB。从行的开头输入，当你点击; ，它将自动缩进。

You can customize the variable C Default Styl. In your emacs go to Options->Customize Emacs->Specific Option, then type c-default-style and set to your choice. By doing this, you don't need to hit TAB. Type from start of the line and as you hit ";" , it will be automatically indented.
