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:
