Boost library incubator URL address
by Edward Diener 12 Oct '16

12 Oct '16

Is the Boost Library Incubator web site down or removed ? I cannot get to it anymore via a URL. I have this URL, http://www.rrsd.com/software_development/blincubator/index.htm, but it just hangs on me.

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.

Re: [boost] [beast] Request for Discussion
by Vinnie Falco 10 Oct '16

There's some great programming and design discussion related to Beast and HTTP going on in the GitHub issues for the project. And there are some interface changes looming. Stakeholders and interested parties should consider participating in these discussions if they would like to influence the outcome: Some of the discussions: HTTP 1 versus 2 namespacing https://github.com/vinniefalco/Beast/issues/121 HTTP/2 design https://github.com/vinniefalco/Beast/issues/122 Expect: 100-continue https://github.com/vinniefalco/Beast/issues/123 `basic_headers` to make better use of allocators and string_ref https://github.com/vinniefalco/Beast/issues/124

[git] some fetch errors
by Raffi Enficiaud 09 Oct '16

Hi all, I see the following errors: """ Fetched in submodule path 'libs/python', but it did not contain 0ca7db361b8a70540c5683ae3ba2219c3352f721. Direct fetching of that commit failed. """ while my agents were checking out version aa407db3a22120496d6c49d2e3bc0b494b5ceb76 of the boost superproject. Does anyone know why am I seeing this? I cannot find rev 0ca7db361b8a70540c5683ae3ba2219c3352f721 in libs/python Thanks, Raffi

To get this topic hopping again, I'll share a bit of news. With help from Howard Hinnant I've opened an issue against the Networking TS to make sure that its algorithms do not place unnecessary requirements on user-defined types: http://cplusplus.github.io/LWG/lwg-active.html#2779 This will affect Beast's buffer sequence adapters (such as buffer_cat).

Boost.Python NumPy extension
by Stefan Seefeld 09 Oct '16

09 Oct '16

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...
