Astyle格式说明

#### Option's Format:选项格式
## ----------------
## 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

## 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.

#### 大括号三种基本风格:
## attach:大括号前一个与上一行在同一行(java)
## break:大括号与前一块隔开为两行 (allman,bsd)
## linux:大括号在class,namespace,function分行,其他不分行(K&R,linux)
## --brackets=attach OR  -a 大括号前一个与上一行在同一行 Attach brackets to pre-block code (i.e. Java style).
## --brackets=break  OR  -b 大括号与前一块隔开为两行  Break brackets from pre-block code (i.e. ANSI C/C++, allman, bsd style).
## --brackets=linux  OR  -l 定义块 和 函数块中的大括号都被处理 Break definition-block brackets and attach command-block brackets.(k/r, linux)
## --brackets=stroustrup  OR  -u  只处理函数中的大括号   Attach all brackets except function definition brackets.

#### 风格花括号Style定义(默认都不处理namespace, 默认都在语句和代码块后分行):
##  --style=allman or --style=bsd or -A1
##  --style=java or -A2
##  --style=k&r or  --style=k/r or -A3
##  --style=stroustrup or -A4
##  --style=whitesmith or -A5
##  --style=banner or -A6
##  --style=gnu or -A7
##  --style=linux or -A8
A3

#### tab选项: 默认tab是4个空格.
## --indent=spaces=#  OR  -s#  默认行缩进为4个空格,可以将#替换为缩进量
s4
## --indent=tab  OR  --indent=tab=#  OR  -t  OR  -t#  行缩进用tab, 续行语句用空格
## --indent=force-tab=#  OR  -T#  行缩进用tab, 续行语句用也用tab
## --indent=force-tab-x OR --indent=force-tab-x=# OR -xT OR -xT#  比较复杂,不建议使用

#### 大括号选项: If no brackets option is set, the brackets will not be changed.
## --attach-namespaces / -xn  namespaces后的大括号不分行
## --attach-classes / -xc class后的大括号不分行
## --attach-inlines / -xl C++中定义的inlines函数的大括号不分行
## --attach-extern-c / -xk  C++中的extern "C" 后的大括号不分行
## --attach-closing-while / -xV  do while中的while条件不分行

#### 缩进选项:
## --indent-classes  OR  -C 缩进类定义中的public private protected标签.
## Indent 'class' blocks, so that the inner 'public:','protected:' and 'private: 
## headers are indented in relation to the class block.
##--indent-modifiers / -xG 类中的public private protected标签缩进改为1/2.
## Indent 'class ' and 'struct' access modifiers, 'public:', 'protected:' and 'private:', one half indent. 
## The rest of the class is not indented. This option is effective for C++ files only.
## If used with indent‑classes this option will be ignored.

## --indent-switches  OR  -S 缩进switch中的case块,case和switch不在同一列
## Indent 'switch' blocks, so that the inner 'case XXX:' headers are indented in relation to the switch block.
S
## --indent-cases  OR  -K 缩进case下面的语句
## Indent case blocks from the 'case XXX:' headers.
## Case statements not enclosed in blocks are NOT indented.

## Add extra indentation entire blocks (including brackets).

## --indent-brackets  OR  -B 缩进大括号
## Add extra indentation to '{' and '}' block brackets.

## --indent-namespaces  OR  -N 缩进命名空间定义行
## Indent the contents of namespace blocks.

## --indent-labels  OR  -L 缩进标签
## 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).

## --indent-preprocessor  OR  -w 缩进多行宏定义
## Indent multi-line #define statements.

## --max-instatement-indent=#  OR  -M#   跨行缩进,比如函数定义中的参数处在多行,那么参数缩进到同一列
## Indent a maximal # spaces in a continuous statement, relative to the previous line.

## --min-conditional-indent=#  OR  -m#
## Indent a minimal # spaces in a continuous conditional belonging to a conditional header.

## Insert empty lines around unrelated blocks, labels, classes, ...
