[python][container] map_indexing_suite for flat_map
by MM 09 Jul '18

09 Jul '18

Hello, I've tried to adapt using myfm = boost::container::flat_map<const T*, V>; with boost::python::map_indexing_suite class_< myfm, myfm* >("myfm") .def( map_indexing_suite<myfm>{} ) ; I get a compile errors: /usr/include/boost/python/detail/invoke.hpp:75:14: error: no match for call > to ‘(const > boost::python::detail::specify_a_return_value_policy_to_wrap_functions_returning<const > T*>) (const T*)’ > ... > Caller = boost::python::detail::caller<const T* (*)(std::pair<const T*, > V>&), default_call_policies ...> I would suspect that there is some function that returns the key_type of the flat_map and takes a single argument of the value_type, but I can't find any. If there's one, I would need pick a return value policy for it. MM

Boost.Beast includes CRLF in HTTP fields
by David Demelier 08 Jul '18

08 Jul '18

Hello, It looks like HTTP response headers are saved with trailing CRLF in the message upon receiption after (async_)read. Since it usually does not add additional valuable information, would it be possible to remove them in next version of Boost.Beast? It will be more convenient as you don't need to trim them when you want to capture the field value. Regards, -- David

I see tutorial sample: https://www.boost.org/doc/libs/1_67_0/libs/spirit/example/qi/mini_xml3.cpp <https://www.boost.org/doc/libs/1_67_0/libs/spirit/example/qi/mini_xml3.cpp> on_error<fail> ( xml , std::cout << val("Error! Expecting ") << _4 // what failed? << val(" here: \"") << construct<std::string>(_3, _2) // iterators to error-pos, end << val("\"") << std::endl ); How print line number, or how print _2 and _3 . If I write _2 instead _4, is compiler error. -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html

[numeric/interval.hpp] compilation on clang++ vs g++
by M B 27 Jun '18

27 Jun '18

This may be a somewhat newbie question.This is cross-posted on stack exchange before I found this list. (https://stackoverflow.com/questions/51062374/different-behavior-with-enable…) I'm having trouble compiling the following piece of boost-based code: ***** #include <boost/numeric/interval.hpp> #include <complex> int main(){ std::complex<boost::numeric::interval<double> > my_interval(1,1); my_interval *= my_interval; return 0;} ***** When I compile using g++ (MacPorts gcc5 5.5.0_1), I get no compilation errors (g++ -std=c++14 main.cpp). When I compile using clang++ (Apple LLVM version 8.1.0 (clang-802.0.38)), I get compilation errors (clang++ -std=c++14 main.cpp). Summarizing the error, it appears that an enable_if in cmath (line 424: std::enable_if<std::is_arithmetic<_A1>::value, bool>::type) is preventing isnan from being defined for boost::numeric::interval<double> (at least in clang++). Am I doing something wrong or is there a work around? I realize that this might be more of a std::complex question than a boost question, but since it involves boost, I thought that I'd ask here. Thank you. The full and complete error is below. ***** Full and Complete Error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/complex:599:9: error: no matching function for call to 'isnan' if (isnan(__x) && isnan(__y)) ^~~~~/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/complex:312:27: note: in instantiation of function template specialization 'std::__1::operator*<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >' requested here *this = *this * complex(__c.real(), __c.imag()); ^main.cpp:6:15: note: in instantiation of function template specialization 'std::__1::complex<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >::operator*=<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >' requested here my_interval *= my_interval; ^/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/cmath:424:25: note: candidate template ignored: disabled by 'enable_if' [with _A1 = boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > >]typename std::enable_if<std::is_arithmetic<_A1>::value, bool>::type
