How can I detect if a template static member function exists?
by Vinnie Falco 16 Oct '16

16 Oct '16

I'd like to write a trait: template<class T> struct has_content_length : std::integral_constant<bool, ...>{}; which detects whether or not a template static member function is present in T. Here's a typical T: struct X { template<bool isRequest, class Body, class Headers> static std::uint64_t content_length( message<isRequest, Body, Headers> const& m); }; How can I detect if X::content_length(m) is callable for any m of type message template?

Re: [boost] [config] Changes to reflect Visual C++ "15" preview 5
by Tom Kent 15 Oct '16

15 Oct '16

I've now added a runner to the test suite with msvc-15.0 (preview 5 installed), it should show up in a couple hours as "teeks99-09o-win2012R2-64on64" (the far right column). The run only took a few minutes instead of an hour or two, so I'm expecting it to look pretty broken. Just glancing at the logs it looks like the compiler isn't even being found. Does this require b2 updates? Tom

[algorithm] New search algorithms
by Зайцев Александр 14 Oct '16

14 Oct '16

Hello. Now in Boost. Algorithm there are 3 algorithms for searching: Knuth-Morris-Prata, Boyer-Moore, Boyer-Moore-Horspool. They are good algorithms, but there are other efficient algorithms like Turbo-Boyer-Moore, Quick Search, etc. You can find some more here: http://www-igm.univ-mlv.fr/~lecroq/string/index.html Now i am working on new search algorithms for Boost.Algorithm. Maybe are there anybody,who familiar with string search algorithms? -- Best regards, Alexander Zaitsev

I would be very interested in seeing if I could adapt those function. Mine are placeholders and I've deliberately postponed the non-trivial task of adding cmath equivalents. It's come up - maybe a couple of times - whether these functions are desired and the response has been to just keep the proposal narrow so they are not included. There are interesting questions regarding how to implement some functions. For example, you surely don't always want the same inputs and outputs from functions involving angles. And hopefully these functions can be constexpr - unlike existing functions. Also, how have you approached the trade-off between speed and accuracy? I went for a very simple sqrt function which is adequate if the value is calculated at compile time but is likely not desirable at run-time. This isn't a problem that floating-point variants face. > I have also benched our fixed_point on bare-metalembedded systems both > 8-bit and 32-bit with verysatisfying efficiency results.

Announcing version 3 of the cxx_dual library
by Edward Diener 11 Oct '16

11 Oct '16

I have created version 3 of the cxx_dual library. version 3 is a large rewrite of the documentation to simplify the use of the library, as well as a change in the directory structure so that the basic usage of the library is through a single header file and the use of a namespace alias, and not through the macro interface. As in: #include <boost/cxx_dual/regex.hpp> void SomeFunction() { cxxd_regex_ns::regex re("A regular expression etc."); bool result(cxxd_regex_ns::regex_match("Some string...",re)); // etc. } What ! No macros ! Actually a few macros still exist for testing which dual library has been chosen and overriding the dual library chosen, but the basic functionality means almost no macros in user code. The library is available at https://github.com/eldiener/cxx_dual.git. What is it ? The Cxx Dual library, or CXXD for short, is a C++ macro header-only library which chooses between using a Boost library or its C++ standard equivalent library for a number of different C++ implementations, while allowing the end-user to use the same code to program either choice. An implementation is a Boost library which has a C++ standard library equivalent whose public interfaces are nearly the same in both cases. An 'implementation' is called a 'mod' for short and each of the possible Boost or C++ standard implementations for that mod are called a 'dual library'. The Cxx Dual library does this by automatically choosing either the Boost library or the C++ standard library for a particular mod, including the correct header file(s) needed for the dual library chosen, and creating a namespace alias for the namespace of the dual library chosen. CXXD also provides a macro-based solution for distinguishing between the Boost version and the C++ standard version of a dual library so that specific code for a particular dual library choice may be written in those cases where the public interfaces diverge.

Boost.Python NumPy extension

Hello, I'm happy to announce that I just merged the NumPy C++ wrappers from https://github.com/ndarray/Boost.NumPy into Boost.Python's development branch. (Online documentation for it can be browsed here: http://boostorg.github.io/python/develop/doc/html/numpy) I'd very much like to be able to merge this into the master branch for the next Boost release (version 1.63). At present I'm using SCons to build Boost.Python (stand-alone, against a separately installed Boost), which is also the infrastructure I use for CI testing (https://travis-ci.org/boostorg/python) I would like to ask for help with integrating the new NumPy extension into the Boost.Build-based build system, such that this will also be picked up by the regular Boost infrastructure. Please refer to https://github.com/boostorg/python/issues/89 if you'd like to help with this. Many thanks ! Stefan -- ...ich hab' noch einen Koffer in Berlin...

Upcoming changes to _MSC_VER
by Gabriel Dos Reis 07 Oct '16

07 Oct '16

Hi, This is a heads up. I spoke with Beman at CppCon about this: the upcoming release of Visual Studio (VS "15") has some changes to how _MSC_VER will be defined at every (future) update. These changes are already implemented in 'VS "15" Preview 5'. The full details are here https://blogs.msdn. microsoft.com/vcblog/2016/10/05/visual-c-compiler-version/ Internal testing showed that some components of Boost source code needed a few changes to use inequalities instead of equalities with _MSC_VER.

Extending Boost.Python with NumPy support
by Stefan Seefeld 04 Oct '16

04 Oct '16

Hello, I'm presently working on a few improvements to the Boost.Python module. As part of this I'm refactoring the numeric API to actually support NumPy. There has been quite a lot of effort we put into this in the past (notably a GSoC project I mentored a few years ago), but we never managed to include this into the Boost master branch, so it's never been formally released. As I'm now getting ready to polish this work off, I wonder whether any of this would require a formal submission as a new Boost library, or whether it can just be done under the Boost.Python umbrella ? I reckon this is somewhat of a gray area, so I'd like to clarify whether there are concrete rules for what changes / additions require a formal review process. Thanks, Stefan -- ...ich hab' noch einen Koffer in Berlin...

[concept_check] convert Concept to trait?
by Vinnie Falco 04 Oct '16

04 Oct '16

I don't see a place to open issues on https://github.com/boostorg/concept_check so I am posting this here. What I want to do is convert a concept into a trait. For example, given the ForwardIterator concept checking class, I would like to write: template<T> using is_ForwardIterator = std::integral_constant<bool, ...>; Which aliases to std::true_type if T meets the requirements of ForwardIterator and false otherwise. Or perhaps a general purpose alias: template<t> using is_concept<T, C> = std::integral_constant<bool, ...>;l Which aliases to std::true_type if T meets the requirements of concept C. Are such things possible, or perhaps already in the library? My preliminary analysis suggests the answers to these questions are no and no. Has this point been brought up elsewhere, and if so where could I find it? Regards
