Given something like: struct MyType { MyType(); // ... private: int i1_; double d_; T1 *pT1_; T2 t2_; }; I'd like the code to generate: struct MyType { MyType() : i1_(0), d_(0.0), pT1_(0), t2_() { } // ... private: int i1_; double d_; T1 *pT1_; T2 t2_; }; It would be easy to write something that just default-constructs the members, but I'd like to make it smart enough to init bools to "false", ints to "0", doubles to "0.0", etc. My questions are: - Are there helper functions in c++-mode that can be used to enumerate member variables, or make life easier? - Is there code to do something like this already (I looked a bit and didn't find exactly what I wanted)? - Is GCC-XML worth looking into? I've looked at the output of a small C++ class and could use Python to do what I want. I haven't started the coding and wanted to get other people's input. Thanks.
