工具/分析器为$ P $#如果pprocessor陈述? [英] Tool/Parser for preprocessor #if statements?
问题描述
我的工作,其中包含许多preprocessor许多C源$ C $ C文件#如果
, #elseif
和的#else
语句。
I am working on many C-sourcecode files which contain many preprocessor #if
, #elseif
and #else
statements.
这语句经常检查了的#define
,例如
This statements often check for a #define
, e.g.
#if(Switch_TestMode == Switch_TestModeON)
/* code 1 */
#else
/*code 2 */
#endif
这通常preprocessor语句都设在C-if语句,这使得源$ C $ C几乎无法读取人类beeings。
Often this preprocessor statements are located within c-if statements which makes the sourcecode nearly unreadable for human beeings.
的的#define
使用范围是这个preprocessor #如果
语句一个额外的文件中定义。
The #define
s used for this preprocessor #if
statements are defined within an extra file.
我的想法是现在有一个工具来做这个的#define
D开关设置,然后只复制源$ C $ C的使用当前#适用线定义/开关设置。
My idea now is to have a tool which checks this #define
d switch settings and then only copies the lines of sourcecode which apply using the current #defines/switch settings.
对于上面的例子,我想获得该只包含一个新的.c文件
For the above example I would like to get a new .c file which contains only
/*code 2 */
假设的#define
的 Switch_TestMode
不等于 Switch_TestModeON
。
是否有工具(免费||成本低),可里面做这份工作吗?
还是我来写这个我自己的preprocessor解析器?
Are there tools (freeware || low-cost) available which do this job? Or do I have to write my own preprocessor parser for this?
(这是不可能的,我使用的做这件工作的特殊参数运行编译器,因为我们公司是创建C源$ C $ C,另一家公司正在编制)。
(It is impossible for me to run the compiler using a special parameter which does this job, because our company is creating the C-sourcecode, another company is compiling.)
感谢您的任何暗示!

推荐答案
尝试 Sunifdef
