Hello. I've been reading a bit about C#'s linq and it's very cool in my opinion. I would like to see something similar in c++, and boost is the ideal place I think. As I would like to see something similar, I started a prototype adapted to c++.
For now I've been playing with the basics:
-from, where and select operators. -it just can be used (for now) with from, where and select, all in a row, but this will change. -it should work with any range: containers, boost.range, etc. -it's just a c++0x version. It works great with lambdas (gcc svn has lambdas). -Can use any boost.fusion sequence as the object type to query. (Although the plan is to be able to give data providers to use to query any type of source.
The prototype works in the following way. For example (C++0x) :
vector<int> numbers = {1, 2, 3, 4, 8, 5, 9 , 24, 19, 15, 12 }
auto query = from(numbers).where([](int i) { return i < 15 && i > 10}). select(fields::full_object);
I've proposed somethign very similar at boost'con 09 for a higher level query library. I'm all for it -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
