很多时候，我们可能会在SI中直接编写代码，但是SI没有代码整理功能，比如整理符合c/c++规范
这时候，很是郁闷．．．但是可以将astyle.exe外挂到SI中，详细步骤如下：
1：从 上下载astyle.exe(开放源码，可以仔细阅读)；
2：将astyle.exe保存到磁盘，这里我放到C:\Program Files\astyle下
在SI菜单栏里，Options-->Custom Commands界面上选择：Add,在弹出对话框写入 Fomat with astyle,
3：在run中添加"C:\Program Files\astyle\astyle.exe" --style=ansi %f，其中，如果astyle.exe所在路径中有空格，务必用＂＂括起来，参数--style=ansi(如果你需要格式化java代码，这个地方改为：--style=java),其它命令参数可以参考astyle的帮助参数"%f"是指作用于当前文件，这个必须的．
4：此外，在此界面上还可以为这个命令设置快捷键，点击＂keys＂，添加你觉得方便的按钮；
5：在SI菜单栏里，Options-->Menu Assignments界面上，将这个命令添加到某工具栏下，在左面的Command列表里找到我们刚才添加的＂Fomat with astyle＂，在右面的Menu中选择你要加到那个菜单下，这里我加到＂Edit＂下，可以在＂Menu Contents＂选择适当位置，点击＂insert＂即可;
OK,世界简单了．．．另外，如何在vc中外挂astyle的代码整理功能，可以参考这篇文档：
下面是标准的程序文档，如果你想了解更多用法，可以一读；如果你只是像我一样日常使用该工具，就可以不看了。
Artistic Style 1.15.3 ()
(created by Tal Davidson, )
Modified edition by Qiongzhu Wan, 2004.09
Usage : astyle [options] < original > Beautified
astyle [options] Foo.cpp Bar.cpp [...]
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.
By default, astyle is set up to indent C/C++/C# 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.
Predefined Styling options:
--------------------
--style=ansi
ANSI style formatting/indenting.
--style=kr
Kernighan&Ritchie style formatting/indenting.
--style=gnu
GNU style formatting/indenting.
--style=java
Java mode, with standard java style formatting/indenting.
--style=linux
Linux mode (i.e. 8 spaces per indent, break definition-block
brackets but attach command-block brackets.
Indentation options:
--------------------
-c or --mode=c
Indent a C, C++ or C# source file (default)
-j or --mode=java
Indent a Java(TM) source file
-s or -s# or --indent=spaces=#
Indent using # spaces per indent. Not specifying #
will result in a default of 4 spacec per indent.
-t or -t# or --indent=tab=#
Indent using tab characters, assuming that each
tab is # spaces long. Not specifying # will result
in a default assumption of 4 spaces per tab.
-T# or --force-indent=tab=# Indent using tab characters, assuming tha
t each
tab is # spaces long. Force tabs to be used in areas
Astyle would prefer to use spaces.
-C or --indent-classes
Indent 'class' blocks, so that the inner 'public:',
'protected:' and 'private: headers are indented in
relation to the class block.
-S or --indent-switches
Indent 'switch' blocks, so that the inner 'case XXX:'
headers are indented in relation to the switch block.
-K or --indent-cases
Indent 'case XXX:' lines, so that they are flush with
their bodies..
-N or --indent-namespaces
Indent the contents of namespace blocks.
-B or --indent-brackets
Add extra indentation to '{' and '}' block brackets.
-G or --indent-blocks
Add extra indentation entire blocks (including brackets).
-L or --indent-labels
Indent labels so that they appear one indent less than
the current indentation level, rather than being
flushed completely to the left (which is the default).
-m# or --min-conditional-indent=#
Indent a minimal # spaces in a continuous conditional
belonging to a conditional header.
-M# or --max-instatement-indent=#
Indent a maximal # spaces in a continuous statement,
relatively to the previous line.
-E or --fill-empty-lines
Fill empty lines with the white space of their
previous lines.
--indent-preprocessor
Indent multi-line #define statements
Formatting options:
-------------------
-b or --brackets=break
Break brackets from pre-block code (i.e. ANSI C/C++ style).
-a or --brackets=attach
Attach brackets to pre-block code (i.e. Java/K&R style).
-l or --brackets=linux
Break definition-block brackets and attach command-block
brackets.
--brackets=break-closing-headers
Break brackets before closing headers (e.g. 'else', 'catch', ..).
Should be appended to --brackets=attach or --brackets=linux.
-o or --one-line=keep-statements
Don't break lines containing multiple statements into
multiple single-statement lines.
-O or --one-line=keep-blocks
Don't break blocks residing completely on one line
-p or --pad=oper
Insert space paddings around operators only.
--pad=paren
Insert space paddings around parenthesies only.
-P or --pad=all
Insert space paddings around operators AND parenthesies.
--convert-tabs
Convert tabs to spaces.
--break-blocks
Insert empty lines around unrelated blocks, labels, classes, ...
--break-blocks=all
Like --break-blocks, except also insert empty lines
around closing headers (e.g. 'else', 'catch', ...).
--break-elseifs
Break 'else if()' statements into two different lines.
Other options:
-------------
--suffix=####
Append the suffix #### instead of '.orig' to original filename.
-X or --errors-to-standard-output
Print errors and help information to standard-output rather than
to standard-error.
-v or --version
Print version number
-h or -? or --help
Print this help message
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.
2. The file called .astylerc in the directory pointed to by the
HOME environment variable ( i.e. $HOME/.astylerc ).
3. The file called .astylerc in the directory pointed to by the
HOMEPATH environment variable ( i.e. %HOMEPATH%\.astylerc ).
If a default options file is found, the options in this file
will be parsed BEFORE the command-line options.
Options within the default option file may be written without
the preliminary '-' or '--'.
