Original Author: Tal Davidson
Usage : astyle [options] Source1.cpp Source2.cpp [...]
astyle [options] < Original > Beautified
When indenting a specific file, the resulting indented file RETAINS the
original file-name. The original pre-indented file is renamed, with a
suffix of ".orig" added to the original filename.
Wildcards (* and ?) may be used in the filename.
A 'recursive' option can process directories recursively.
可以用通配符指定要处理的文件,用-r递归处理子目录
By default, astyle is set up to indent C/C++/C#/Java files, with 4 spaces
per indent, a maximal indentation of 40 spaces inside continuous statements,
and NO formatting.
Option's Format:
----------------
Long options (starting with '--') must be written one at a time.
Short options (starting with '-') may be appended together.
Thus, -bps4 is the same as -b -p -s4.

Default options file:
---------------------
Artistic Style looks for a default options file in the
following order:
1. The contents of the ARTISTIC_STYLE_OPTIONS environment
variable if it exists.
从ARTISTIC_STYLE_OPTIONS环境变量读取选项
2. The file called .astylerc in the directory pointed to by the
HOME environment variable ( i.e. $HOME/.astylerc ).
从/home文件夹中的.astylerc文件读取选项
3. The file called astylerc in the directory pointed to by the
USERPROFILE environment variable ( i.e. %USERPROFILE%\astylerc ).
从USERPROFILE下的astylerc文件读取选项信息
If a default options file is found, the options in this file
will be parsed BEFORE the command-line options.
Long options within the default option file may be written without
the preliminary '--'.
--options的用法:
我的在source insight中的设置为 AStyle.exe --options=D:\TOOLS\AStyle\astyle.cfg %f
astyle.cfg内容为:
-s4 -SKFxpUcnlaC
#井号表示是注释
#-s4 行缩进用4个空格
#-S switch 与case不同列,case缩进
#-K 缩进case下面的语句
#-F 空行分隔无关块
#-x 删除多余空行
#-p 操作符两端出入空格
#-U 移除括号两端多余空格
#-c tab转空格
#-n 不做备份
#-l 处理定义和函数中的大括号
#-a 大括号保留在上一行
