[Review] Type Traits Introspection library by Edward Diener starts tomorrow Friday 1
by Joel Falcou 15 Jul '11

15 Jul '11

According to the schedule, review for the Type Traits Introspection library by Edward Diener starts this friday and run till July 10th. =========== What is it? =========== The TTI library, which is an abbreviation for the 'Type Traits Introspection' library, allows a programmer to introspect at compile time the inner elements of a C++ type. The introspection process depends on specifying the name of the inner element by different macros for different types of elements, and then using a generated metafunction to determine whether that element exists within the enclosing type. The inner elements which can be introspected are type, class template, member data, member function, static member data, and static member function. The TTI library is based on the type_traits_ext portion of the Concept Traits Library, with improvements and additions, and also reproduces functionality ( without changing existing code ), for the purposes of completeness, from Boost.MPL regarding introspection of types and templates. The purpose of the library is to provide a consistent set of interfaces for doing compile-time introspection of a type, which other template metaprogrammers can use in their code. If you are at all interested in compile-time introspection of types, please take a look at the functionality of this library. =================== Getting the library =================== The library is available at http://svn.boost.org/svn/boost/sandbox/tti/ Note that this repository will be updated up to next thursday by Edward. =================== Writing a Review =================== The reviews and all comments should be submitted to the developers list, and the email should have "[TTI] Review" at the beginning of the subject line to make sure it's not missed. Please explicitly state in your review whether the library should be accepted. The general review checklist: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain? And finally, every review should answer this question: - Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion.

Re: [boost] [Boost-users] The last (I think) of the Boostcon videos
by Pascal Dennerly 15 Jul '11

Definite +1 from me too! Although I'm still having problems viewing http://blip.tv/boostcon/haskell-the-pseudocode-language-for-c-template-meta…. Keeps on telling me "Sorry, this episode may have just been added to blip.tv and isn't quite ready to watch yet. Please try again later." Does anyone else see this? Pascal

[Spirit] bin_float parser
by Vitaly Budovski 15 Jul '11

15 Jul '11

Hi, Now that Boost 1.47 has been released, I'm hoping to get the following parsers added for the next version. Attempt #2, which has hopefully addressed all of the issues from the previous submission. Please see attached diffs and test case. Cheers, Vitaly

BOOST_DATE_TIME_NO_LIB
by gpolo1＠tampabay.rr.com 15 Jul '11

15 Jul '11

Without the #define, boost tries to automatically link with the appropriate library. It just so happens that my boost installation does not have this library. So I was wondering if I even need this library? Aren't all boost classes compiled via hpp. I #defined BOOST_DATE_TIME_NO_LIB in my header file and the program compiles and works fine. So what is the purpose of this definition. I am using boost 1.32 along with Visual Studio 6.0. I have compiled it on Linux successfully, but I have not ran it yet.

Hi, I have read the Release notes. I wanted to confirm a few things with respect to Boost 1.47.0 : 1. Is RHEL 5.5 supported? 2. Is there a 64-bit support?

[AutoIndex] The AutoIndex tool is now in Boost Trunk.
by John Maddock 14 Jul '11

14 Jul '11

AutoIndex is now in Trunk, there are numerous small improvements based on the feedback from the review, so those existing users are encouraged to upgrade to the latest and greatest. I made some changes to the way HTML indexes are produced, so that formatting is now handled by the stylesheets, if anyone would like to suggest improvements to the CSS I'm sure they'd be most welcome, examples here: http://svn.boost.org/svn/boost/trunk/libs/type_traits/doc/html/index/s14.ht… Regards, John.
