用astyle格式化代码

有时候从网上copy来的代码格式不怎么友好，一行行的改，我实在不乐意。之前在windows下用VS自带的ALT + F8着实爽了一把，当然还有CodeBlocks的astyle……

现在linux下我也想这样，VS是不用想了，astyle倒是可以……

1、astyle介绍

网址：http://astyle.sourceforge.net/

这里有源码，自己下载后解压安装下就可以了。

风格选项：

Bracket Style Options: 
---------------------- 
    --style=allman  OR  --style=ansi  OR  --style=bsd 
        OR  --style=break  OR  -A1 
    Allman style formatting/indenting. 
    Broken brackets. 

    --style=java  OR  --style=attach  OR  -A2 
    Java style formatting/indenting. 
    Attached brackets. 

    --style=kr  OR  --style=k&r  OR  --style=k/r  OR  -A3 
    Kernighan & Ritchie style formatting/indenting. 
    Linux brackets. 

    --style=stroustrup  OR  -A4

    --style=whitesmith  OR  -A5 
    Whitesmith style formatting/indenting. 
    Broken, indented brackets. 
    Indented class blocks and switch blocks. 

    --style=banner  OR  -A6 
    Banner style formatting/indenting.

    Indented class blocks and switch blocks. 

    --style=gnu  OR  -A7 
    GNU style formatting/indenting.

    --style=linux  OR  -A8 
    Linux style formatting/indenting. 
    Linux brackets, minimum conditional indent is one-half indent. 

    --style=horstmann  OR  -A9 
    Horstmann style formatting/indenting. 
    Run-in brackets, indented switches. 

    --style=1tbs  OR  --style=otbs  OR  -A10 
    One True Brace Style formatting/indenting. 
    Linux brackets, add brackets to all conditionals. 

    --style=pico  OR  -A11 
    Pico style formatting/indenting. 
    Run-in opening brackets and attached closing brackets. 
    Uses keep one line blocks and keep one line statements. 

    --style=lisp  OR  -A12 
    Lisp style formatting/indenting. 
    Attached opening brackets and attached closing brackets. 
    Uses keep one line statements.

2、bash中使用

如下源码：

#include <stdio.h>
int main()
{int i;printf("Just a test!\n");for(i=0;i<10;++i)printf("%d\n",i);}return 0;}

执行命令：astyle test1.c

效果如下：

#include <stdio.h>
int main()
{
    int i;
    printf("Just a test!\n");
    for(i=0; i<10; ++i) {
        printf("%d\n",i);
    }
    return 0;
}

当然还有其他选项：

astyle --style=bsd test1.c

astyle --style=gnu test1.c

……

3、在vim中使用 

:%!astyle (simple case - astyle default mode is C/C++) 

或者 

:%!astyle --mode=c --style=ansi -s2 (ansi C++ style, use two spaces per indent level) 

或者 

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

4、批量格式化

bash命令如下：

for f in $(find . -name '*.c' -or -name '*.cpp' -type f); do astyle $f; done

即如下bash脚本：

#! /bin/bash

for f in $(find . -name '*.c' -or -name '*.cpp' -type f)
do
astyle $f
done

好，就这些了，希望对你有帮助。
