Tagging a class definition with a macro

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

#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:

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