           astyle是一个开源工具,它可以方便的将代码格式化成自己想要的样式而不必人工修改。可以到网站()上下载源码自己编译,也可以使用指令(apt-get install astyle)安装。


下面介绍一下astyle的简单使用。例如有以下的源码:
  1. #include <stdio.h>
  2. int main()
  3. {int i;printf("Just a test!\n");for(i=0;i<10;++i)printf("%d\n",i);}return 0;}
然后在终端下输入一下指令:
  1. astyle test1.c
效果如下:
  1. #include <stdio.h>
  2. int main()
  3. {
  4.     int i;
  5.     printf("Just a test!\n");
  6.     for(i=0; i<10; ++i) {
  7.         printf("%d\n",i);
  8.     }
  9.     return 0;
  10. }

当然也可以加上一些选项,例如“astyle --style=bsd test1.c”,“ astyle --style=gnu test1.c”等等。


vim中的命令模式下,可以使用下面的某一种方式来格式化代码。

  1. %!astyle (simple case - astyle default mode is C/C++)
或者
  1. %!astyle --mode=c --style=ansi -s2 (ansi C++ style, use two spaces per indent level)

或者

  1. 1,40!astyle --mode=c --style=ansi (ansi C++ style, filter only lines 1-40)

为方便使用,可以把它写成一个脚本,代码如下:

  1. #! /bin/bash

  2. for f in $(find . -name '*.c' -or -name '*.cpp' -type f)
  3. do
  4.     astyle $f
  5. done
在格式化完代码后,会生成一个后缀为orig的文件,将脚本更改如下:
  1. #! /bin/bash

  2. for f in $(find . -name '*.c' -or -name '*.cpp' -or -name '*.h' -type f)
  3. do
  4.      astyle $f
  5. done

  6. # after formate the code,we need to rm '*.orig' files
  7. for f in $(find . -name '*.orig' -type f)
  8. do
  9.      rm $f
  10. done


astyle其使用说明如下:

点击(此处)折叠或打开

  1. Usage : astyle [options] Source1.cpp Source2.cpp [...]
  2. astyle [options] < Original > Beautified

  3. When indenting a specific file, the resulting indented file RETAINS the
  4. original file-name. The original pre-indented file is renamed, with a
  5. suffix of ".orig" added to the original filename.

  6. Wildcards (* and ?) may be used in the filename.
  7. A 'recursive' option can process directories recursively.

  8. By default, astyle is set up to indent C/C++/C#/Java files, with four
  9. spaces per indent, a maximal indentation of 40 spaces inside continuous
  10. statements, a minimum indentation of eight spaces inside conditional
  11. statements, and NO formatting options.

  12. Option's Format:
  13. ----------------
  14. Long options (starting with '--') must be written one at a time.
  15. Short options (starting with '-') may be appended together.
  16. Thus, -bps4 is the same as -b -p -s4.

  17. Predefined Style Options:
  18. -------------------------
