Hi Ter,

Believe me I did a search and read tons of posts. I understood that 
parsing C++ was difficult (I had a look at the grammar, furtively 
though). But I would think that parsing the C++ code just to add 
some "easy funtions" like adding a toString(); function to all 
classes wouldn't be that hard.

For instance a class 

classA{ 
int i;
int j;
...
}

Parsing the code would generate

classA::toString(){
cout << "i: " << i << ", " << "j: " << j << endl;
....
}


Is that possible with ANTLR?

I read once about some product that parses C++ and offers a Script 
like language (interface) to walk the tree and generate C++ code or 
whatever. But I cannot find it anymore... 

Anyways... I'm really in an extreemly bad mood :(. I accepted some 
project and I'm stuck now... I have been told that there exists some 
C++ grammar and that could be easily done with ANTL. 

Apparently I should have investigated the matter further!

Thank you in any case :)
