[math] Contribution and TODO-list implementation.
by Bikineev 06 Nov '13

06 Nov '13

Hello. I'm russian student. My department is Applied Math. I need to make my magister work and I would like to relate it with Boost.Math development. I think this work could be something like implementation of tasks mentioned in TODO-list. New feature development may take a long time. In the best case, I would be glad to take job and reviewer for it. If anyone has an idea - I'm ready to take serious and big job for 1,5 years. Thanks.

Boost API System or Library Calls ..
by Rahul Mathur 06 Nov '13

06 Nov '13

Out of curiosity, wish to know if BOOST ASIO calls like - boost::asio::read() boost::asio::transfer_all() boost::asio::write() BOOST LEXICAL calls like - boost::lexical_cast<std::string>() BOOST POSIX TIME calls like - boost::posix_time::microsec_clock::universal_time() boost::posix_time::microsec_clock::ptime() are LIBRARY or SYSTEM calls. How to know which calls of BOOST are SYSTEM and LIBRARY calls? Thanks.

Re: [boost] [modularization] Dependency to Boost.Exceptionunavoidable?
by Ahmed Charles 05 Nov '13

05 Nov '13

What about combining throw_exception.hpp and exception.hpp and move that header to config, since it won't depend on anything else and only really does configuration anyways? Note, if you don't like config as a choice, the new version of detail which only depends on config sounds nice as well. ________________________________ From: Emil Dotchevski Sent: 11/3/2013 12:29 PM To: boost(a)lists.boost.org Subject: Re: [boost] [modularization] Dependency to Boost.Exceptionunavoidable?

[unordered] Visual C++ 2013 initializer_list overload failure.
by Daniel James 05 Nov '13

05 Nov '13

Hi, I'm getting some test failures for inserting an initializer_list into the unordered containers: http://www.boost.org/development/tests/trunk/developer/output/teeks99-10-wi… I don't have access to Visual C++ 12 to investigate this. This is just a guess, but I think the problem is converting an initializer_list of string literals to an initializer list of std::string. This works okay with clang and g++ so I assume it's allowed. A minimal test might be something like the following (although it might not). #include <initializer_list> #include <string> template <typename T> struct thing { void insert(T const&) {} void insert(T&&) {} void insert(std::initializer_list<T>) {} }; int main() { thing<std::string> x; x.insert("a"); x.insert({"a"}); x.insert({"a", "b"}); }

[tweener] Doxygen documentation issues
by Julien Jorge 05 Nov '13

05 Nov '13

Hi, I am writing the documentation of Boost.Tweener and I encounter various difficulties. One of them is the generation of the class documentation with doxygen. It seems that it cannot extract the class and member documentation from .ipp files. I like to document the methods of my classes near the implementation. In Boost.Tweener, most of the class documentation is then in the .ipp files and I have written the following lines in the Jamfile.v2: import quickbook ; using boostbook ; using doxygen ; doxygen reference : [ glob ../../../boost/tweener/*.hpp ] [ glob ../../../boost/tweener/detail/*.hpp ] [ glob ../../../boost/tweener/detail/impl/*.ipp ] [ glob ../../../boost/tweener/detail/impl/easing/*.ipp ] [ glob ../../../boost/tweener/easing/*.hpp ] But when I try to build the documentation, I have the following error: boost_1_52_0/tools/build/v2/build/generators.jam:1085: in ensure-type from module generators error: target { ../../../boost/tweener/detail/impl/tweener_group.ipp. } has no type Moreover, if I remove the ipp files, the generation of the documentation does not fail but the doxygen documentation is not extracted, except for the private members. So, how can I also disable the extraction of the private members in the documentation? You can check the Jamfile.v2 in the git repository of the project: http://libclaw.git.sourceforge.net/git/gitweb.cgi?p=libclaw/boost-tweener;a… Regards, Julien

[modularization] Modularizing Boost (modularization)
by Stephen Kelly 05 Nov '13

05 Nov '13

Hi there, my plan for modularizing and modernizing Boost was roughly this: * Phase 0 - remove dead weight by bumping compiler feature requirements * Phase 1 - move some files around so that the modularized repos form a mostly directed graph * Phase 2 - Form some kind of 'boost core library' or 'boost feature normalization library' from the guts of existing libraries like type_traits, static_assert, config mpl and utilities. * Phase 3 - Try to port the mpl to variadic templates so that the dependency on Boost.PP is not needed when variadic templates are available. I recommend completing up to phase 2 before migrating to git, as otherwise files will have to be deleted from one repo, and added to another without history. Phase 0 is aborted, so let's look at phase 1. [Note: This should go without saying, but my experience on this list tells me it needs to be said: * I do not propose making many commits with the commit message 'migrate' * The below is scripted for your understanding only. Scripting gives an exactness which prose does not, and allows reproducibility. Don't take it too literally. * Of course, forwarding headers should be understood to be left behind when a file is moved, where possible. * Don't cry too loudly about where I'm moving files to. See Phase 2 above, and understand that this is partly only an experiment to see how modularization can be done. EndNote] If the dependencies between repositories are analysed, the result is this graph: http://steveire.com/boost/graph_all.dot http://steveire.com/boost/graph_all_small.png There are 104 nodes and 1159 edges. Each edge is a real dependency which exists between repos, and which will exist between boost modularized packages. They should not be considered optional.

Looking at the entire graph again, we get this: http://steveire.com/boost/graph_final.dot http://steveire.com/boost/graph_final_small.png Obviously, this is not perfect, but it is a beginning, and it is mostly now a directed graph. Any comments? Thanks, Steve.

[parameter] referring to argument types in BOOST_PARAMETER_FUNCTION return values
by Erik Erlandson 05 Nov '13

05 Nov '13

There is documentation that demonstrates using boost::parameter::value_type<> to extract the type of an argument in the boost::parameter library. However, the example does *not* use the BOOST_PARAMETER_FUNCTION() macro, and so the resulting function doesn't benefit from all the features you can get from that macro: Section 3.2.2: http://www.boost.org/doc/libs/1_54_0/libs/parameter/doc/html/index.html#mor… I was able to fairly easily obtain the same kind of arg type information inside of a BOOST_PARAMETER_FUNCTION() declaration, which I show in this example: https://gist.github.com/erikerlandson/7319975 To come up with that, I had to throw '-E' and examine the macro expansions to determine that 'Args' is the appropriate argument-pack template name to use. In other words, what I did doesn't appear to be officially supported: // not officially documented or supported? (typename boost::parameter::value_type<Args, tag::c, int>::type) However, I don't see any barrier to officially supporting the above. All it requires is a promise that 'Args' is the template name that will be generated by the macros. Alternatively, provide a new utility macro, such as: #define BOOST_PARAMETER_ARG_TYPE(arg_name) typename boost::parameter::value_type<[template arg name], [namespace]::arg_name, int>::type

[modularization] Improving/splitting up detail
by John Maddock 05 Nov '13

05 Nov '13

Lets say we wanted boost/detail to depend on nothing but config, here's what it would take: boost/detail/algorithm.hpp Used by graph lib only, suggest it's moved there. boost/detail/allocator_utilities.hpp Used by multi index, statechart and flyweight, suggest move to new "common" module. boost/detail/atomic_count.hpp Depends on smart_ptr's details only, suggest those details are moved to "detail" module. boost/detail/binary_search.hpp Used by python and test, move to "common". boost/detail/bitmask.hpp Only external dependency is boost/cstdint.hpp, either move to "common", or else move cstdint.hpp to "config". boost/detail/call_traits.hpp Move to call_traits (should be there already). boost/detail/catch_exceptions.hpp Only external dependency is boost/cstdint.hpp, suggest latter is moved to config. boost/detail/compressed_pair.hpp Move to compressed pair (should be there already). boost/detail/endian.hpp Move to "predef" boost/detail/has_default_constructor.hpp File appears to be unused, and not very useful, suggest we remove it. boost/detail/identifier.hpp File appears to be unused, suggest we remove it. boost/detail/indirect_traits.hpp Used by iterator and python, move to "common" boost/detail/is_incrementable.hpp Move to common, or better modify the libraies using this to use the newer type_traits equivalents. boost/detail/is_sorted.hpp Used by graph and range, move to "common" boost/detail/is_xxx.hpp Used by parameter and python, move to "common" boost/detail/iterator.hpp I suspect this may be obsolete now compiler requirements have been bumped, but whatever it's still used by multiple libs: move to "common" boost/detail/lcast_precision.hpp Only used by lexical_cast, move it there. boost/detail/lightweight_mutex.hpp Only extern dependency is smart_ptr's details, suggest move those to detail. boost/detail/named_template_params.hpp Appears to be unused, suggest we remove. boost/detail/numeric_traits.hpp Used by graph and iterator, move to "common" boost/detail/ob_compressed_pair.hpp Move to compressed pair, might also be obsolete by now. boost/detail/quick_allocator.hpp Only external dependency is smart_ptr's details, suggest those are moved here. Or since only serialization uses this, move this file there... boost/detail/reference_content.hpp Used by optional and variant, move to "common". boost/detail/winapi/* Depends on boost/cstdint.hpp only, suggest that belongs to config. Everything else in detail has no dependencies other than config. Thoughts? John.
