Andreas,
I need some advice regarding Wave. What I want to do is to operate with Wave on a token stream and extract the token stream representing macro calls after expansion. The twist is that I want the token stream after expansion to have the positions that another preprocessor would see on the already expanded output from Wave. E.g: #define MACRO_CALL int x; int main(){ MACRO };
Exands into #line 2 int main(){ int x; };
Where 'int x' should have a position of line 3 instead of line 1 after expansion. I also want the column number to represent what we see on line 3 instead of what we see on line 1. Is this possible ?
Ok, I've added a new pp hook (what else? :-P) to Wave:
///////////////////////////////////////////////////////////////////////////
//
// The function 'generated_token' will be called by the library whenever a
// token is about to be returned from the library.
//
// The parameter 'ctx' is a reference to the context object used for
// instantiating the preprocessing iterators by the user.
//
// The parameter 't' is the token about to be returned from the library.
// This function may alter the token, but in this case it must be
// implemented with a corresponding signature:
//
// Token const&
// generated_token(Context const& ctx, Token& t);
//
// which makes it possible to modify the token in place.
//
// The default behavior is to return the token passed as the parameter
// without modification.
