My questions (please refer to the code):
<snip> Hi Hicham, First let me apologize for not answering your questions the first time you posted them. I thought, "That's a lot of questions. I'll get to it when I have time." And I just haven't. Some of your questions are easy, though, so I'll give you some tips and get to the rest as time allows. proto::_ can only match types, not non-type template parameters, so you need to change constant_tag to take an MPL Integral Constant. The first parameter to proto::extends must be an expression type, so on line 47, you should probably have "typename proto::terminal<constant_tag<subscript> >::type", or something. On line 56, make it: proto::terminal< proto::convertible_to<double> > to match any terminal expression that is convertible to a double. (It says so much in the users' guide in the section "fuzzy and exact matches of terminals".) You really need to reread the section on domains again. The parameter to proto::generator must be an expression extension class template. That's all I have for now. Good luck. And be sure to check the docs, because you could have found many of these answers there. -- Eric Niebler BoostPro Computing http://www.boostpro.com
