Tagging a class definition with a macro

Let's say we have following macro that defines a class definition:

view plaincopy to clipboardprint?

1. #define DEFINE_A_CLASS(aClass) \  
2.     class aClass: public Base<aClass##Req, aClass##Res>  
3.   
4. DEFINE_A_CLASS(Foo)  
5. {  
6.     public:  
7.         Foo() : mBar(0)  
8.         {  
9.         }  
10.     public:  
11.         int mBar;  
12. };  

#define DEFINE_A_CLASS(aClass) \ class aClass: public Base<aClass##Req, aClass##Res> DEFINE_A_CLASS(Foo) { public: Foo() : mBar(0) { } public: int mBar; };

To make the exuberent-ctags to tag this file correctly, you can use --regex-<LANG> option:

1. ctags --fields=+iaS --extras=+q --languages=C++ --regex-c++='/DEFINE_ACTION_CLASS\(([A-Za-z][A-Za-z0-9_]*)\)/\1/c,class,class definition/'  

ctags --fields=+iaS --extras=+q --languages=C++ --regex-c++='/DEFINE_ACTION_CLASS\(([A-Za-z][A-Za-z0-9_]*)\)/\1/c,class,class definition/'
