Is there any progress on a TR1 conforming tuples implementation? I seem to remember it was going to be rewritten as part of the Phoenix code?
Fusion. The fusion code in the spirit directory *is-a* conforming tuple implementation. It's been there since 1.31. We've just
Oops. Lemme rephrase: The fusion code in the spirit directory *is-a* TR1 conforming tuples implementation.
I've tried converting the TR1 lib to use that implementation but I'm having trouble with the std::pair interface which appears not to work:
tuple_size<std::pair<int, long> > doesn't have a data member "value" apparently.
BOOST_STATIC_ASSERT((::boost::is_same< ::std::tr1::tuple_element<1, std::pair<int, long> >::type, long>::value));
Fails, I'm not sure what type tuple_element is reporting though.
Finally the "get" function appears not to work with pairs.
Oops, I knew I missed something. Well, that's easy enough to add. In fact, the latest Fusion (V2) has those interfaces. I can backport them to Fusion-1 in the weekend. Is that ok?
BTW is this implmentation documented anywhere?
Sorry, no. We're documenting Fusion-V2 though, the version that I asked a boost review for. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
