You might look at the fold<> transform (I suggest you run the sources through the preprocessor first). And then try to wrap your head around the fold_to_list<> transform to see how the runtime component of the transform works. Once you understand that, you'll know proto's transforms inside and out.
Eric,
I've tried to get boost build to create a preprocessor output file without success. I've had to use make to do that; consequently, I've had to have 2 methods of building. Have you been able to create some boost build v2 rules that produce the preprocessor output? If so, could you publish it. I did pose this question to the boost build list:
I simply do it by hand, going to the directory containing (for instance) fold.hpp and running: g++ -E -P -C -I<top of boost tree> -xc++ fold.hpp > fold.pp regards, Maurizio
