Emacs 重新缩进整个 C++缓冲

发布于 2024-10-01 04:28:56 字数 53 浏览 2 评论 0原文

我有一个 C++ 代码文件，但有相当难看的缩进。我如何告诉 emacs 对文件重新应用缩进？

Cx h CM-\

这两个命令选择整个缓冲区并运行 indent-region。

这是我放置在 ~/.emacs.d/defuns.el 文件中的“缩进整个缓冲区”代码。我采取了额外的步骤并将其绑定到快捷键 Cx \。这也将清除所有悬挂的空白，并将制表符转换为其空格等效表示。

(defun indent-buffer ()                                                                                                                                                            
  "Indents an entire buffer using the default intenting scheme."                                                                                                                   
  (interactive)                                                                                                                                                                    
  (point-to-register 'o)                                                                                                                                                           
  (delete-trailing-whitespace)                                                                                                                                                     
  (indent-region (point-min) (point-max) nil)                                                                                                                                      
  (untabify (point-min) (point-max))                                                                                                                                               
  (jump-to-register 'o))                                                                                                                                                           

(global-set-key "\C-x\\" 'indent-buffer)

编辑，合并下面的 @JSONs 建议将为您提供一个看起来像这样的 defun：

(defun indent-buffer ()                                                                                                                                                            
  "Indents an entire buffer using the default intenting scheme."                                                                                                                   
  (interactive)                                                                                                                                                                    
  (save-excursion                                                                                                                                                                  
    (delete-trailing-whitespace)                                                                                                                                                   
    (indent-region (point-min) (point-max) nil)                                                                                                                                    
    (untabify (point-min) (point-max))))

我对此进行了测试，它的工作原理就像以前一样。感谢您指出 JSON。

Here's the "indent entire buffer" code I place in my ~/.emacs.d/defuns.el file. I took the extra step and bound it to a quick key, C-x \. This one also will clear out all your hanging whitspace as well as convert tab characters into their space equivalent representation.

(defun indent-buffer ()                                                                                                                                                            
  "Indents an entire buffer using the default intenting scheme."                                                                                                                   
  (interactive)                                                                                                                                                                    
  (point-to-register 'o)                                                                                                                                                           
  (delete-trailing-whitespace)                                                                                                                                                     
  (indent-region (point-min) (point-max) nil)                                                                                                                                      
  (untabify (point-min) (point-max))                                                                                                                                               
  (jump-to-register 'o))                                                                                                                                                           

(global-set-key "\C-x\\" 'indent-buffer)

Edit, incorporating @JSONs suggestion below will give you a defun that looks like this instead:

(defun indent-buffer ()                                                                                                                                                            
  "Indents an entire buffer using the default intenting scheme."                                                                                                                   
  (interactive)                                                                                                                                                                    
  (save-excursion                                                                                                                                                                  
    (delete-trailing-whitespace)                                                                                                                                                   
    (indent-region (point-min) (point-max) nil)                                                                                                                                    
    (untabify (point-min) (point-max))))

I tested this out and it works just like before. Thanks for pointing that out JSON.

选择整个缓冲区并执行 Mx indent-region

(defun iwb ()
  "indent whole buffer"
  (interactive)
  (delete-trailing-whitespace)
  (indent-region (point-min) (point-max) nil)
  (untabify (point-min) (point-max)))

你可以使用这个小宏（我从 http://emacsblog.org 复制这个/2007/01/17/indent-whole-buffer/）

(defun iwb ()
  "indent whole buffer"
  (interactive)
  (delete-trailing-whitespace)
  (indent-region (point-min) (point-max) nil)
  (untabify (point-min) (point-max)))

You can use this little macro(i copied this from http://emacsblog.org/2007/01/17/indent-whole-buffer/)
