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
