[iterator] transform_iterator and move-only types
by Nathan Ridge 25 Aug '12

25 Aug '12

Hi, The following code fails to compile for me: #include <memory> #include <boost/iterator/transform_iterator.hpp> std::unique_ptr<int> foo(int i) { return std::unique_ptr<int>(new int(i)); } int main() { int a[5] = {1, 2, 3, 4, 5}; auto it = boost::make_transform_iterator(a, foo); } The error message I get with GCC 4.8 is pasted below. I think this should work because returning a move-only type from a function by value is a perfectly valid thing to do. Do you agree? Should I file a bug? Thanks, Nate In file included from boost/iterator/iterator_categories.hpp:20:0, from boost/iterator/iterator_adaptor.hpp:14, from boost/iterator/transform_iterator.hpp:12, from test.cpp:2: boost/type_traits/is_convertible.hpp: In instantiation of 'const bool boost::detail::is_convertible_basic_impl<std::unique_ptr<int>&, std::unique_ptr<int> >::value': boost/type_traits/is_convertible.hpp:296:5: required from 'const bool boost::detail::is_convertible_impl<std::unique_ptr<int>, std::unique_ptr<int> >::value' boost/type_traits/is_convertible.hpp:419:1: required from 'struct boost::is_convertible<std::unique_ptr<int>, std::unique_ptr<int> >' boost/mpl/aux_/nested_type_wknd.hpp:26:31: required from 'struct boost::mpl::aux::nested_type_wknd<boost::is_convertible<std::unique_ptr<int>, std::unique_ptr<int> > >' boost/mpl/aux_/preprocessed/gcc/and.hpp:23:8: required from 'struct boost::mpl::aux::and_impl<true, boost::is_convertible<std::unique_ptr<int>, std::unique_ptr<int> >, mpl_::bool_<true>, mpl_::bool_<true>, mpl_::bool_<true> >' boost/mpl/aux_/preprocessed/gcc/and.hpp:48:8: required from 'struct boost::mpl::and_<boost::is_convertible<boost::random_access_traversal_tag, boost::single_pass_traversal_tag>, boost::is_convertible<std::unique_ptr<int>, std::unique_ptr<int> >, mpl_::bool_<true>, mpl_::bool_<true>, mpl_::bool_<true> >' boost/mpl/if.hpp:67:11: [ skipping 6 instantiation contexts, use -ftemplate-backtrace-limit=0 to disable ] boost/iterator/detail/facade_iterator_category.hpp:187:8: required from 'struct boost::detail::facade_iterator_category<boost::random_access_traversal_tag, std::unique_ptr<int>, std::unique_ptr<int> >' boost/iterator/iterator_facade.hpp:104:17: required from 'struct boost::detail::iterator_facade_types<std::unique_ptr<int>, boost::random_access_traversal_tag, std::unique_ptr<int>, long int>' boost/iterator/iterator_facade.hpp:621:9: required from 'class boost::iterator_facade<boost::transform_iterator<std::unique_ptr<int> (*)(int), int*, boost::use_default, boost::use_default>, std::unique_ptr<int>, boost::random_access_traversal_tag, std::unique_ptr<int>, long int>' boost/iterator/iterator_adaptor.hpp:261:9: required from 'class boost::iterator_adaptor<boost::transform_iterator<std::unique_ptr<int> (*)(int), int*, boost::use_default, boost::use_default>, int*, std::unique_ptr<int>, boost::use_default, std::unique_ptr<int>, boost::use_default>' boost/iterator/transform_iterator.hpp:74:9: required from 'class boost::transform_iterator<std::unique_ptr<int> (*)(int), int*, boost::use_default, boost::use_default>' test.cpp:12:52: required from here boost/type_traits/is_convertible.hpp:136:23: error: use of deleted function 'std::unique_ptr<_Tp, _Dp>::unique_ptr(const std::unique_ptr<_Tp, _Dp>&) [with _Tp = int; _Dp = std::default_delete<int>]' static bool const value = sizeof( boost::detail::checker<To>::_m_check(_m_from, 0) ) ^ In file included from c++/4.8.0/memory:81:0, from test.cpp:1: c++/4.8.0/bits/unique_ptr.h:259:7: error: declared here unique_ptr(const unique_ptr&) = delete; ^ In file included from boost/iterator/iterator_categories.hpp:20:0, from boost/iterator/iterator_adaptor.hpp:14, from boost/iterator/transform_iterator.hpp:12, from test.cpp:2: boost/type_traits/is_convertible.hpp:129:41: error: initializing argument 1 of 'static boost::type_traits::yes_type boost::detail::checker<T>::_m_check(T, int) [with T = std::unique_ptr<int>; boost::type_traits::yes_type = char]' static boost::type_traits::yes_type _m_check(T, int); ^

[phoenix] Help needed with a custom terminal
by Andrey Semashev 25 Aug '12

25 Aug '12

Hi, I'm trying to define a custom terminal that acts as a replacement of operator<< in expressions when the right argument of the operator is of my special type. The terminal aggregates its left subexpression which results in reference to a stream, and result type of the terminal is the same reference. In short, it looks like this: namespace my { struct argument { std::string m_value; explicit argument(std::string const& value); }; template< typename LeftT > class output_terminal { public: typedef void _is_my_terminal; //! Self type typedef output_terminal this_type; //! Result type definition template< typename > struct result; template< typename ContextT > struct result< this_type(ContextT) > { typedef typename remove_cv< typename remove_reference< ContextT >::type >::type context_type; typedef typename phoenix::evaluator::impl< typename LeftT::proto_base_expr&, context_type, phoenix::unused >::result_type type; }; template< typename ContextT > struct result< const this_type(ContextT) > { typedef typename remove_cv< typename remove_reference< ContextT >::type >::type context_type; typedef typename phoenix::evaluator::impl< typename LeftT::proto_base_expr const&, context_type, phoenix::unused >::result_type type; }; private: //! Left argument actor LeftT m_left; //! Right argument std::string m_right; public: //! Initializing constructor output_terminal(LeftT const& left, std::string const& right); //! Invokation operator template< typename ContextT > typename result< const this_type(ContextT) >::type operator() (ContextT const& ctx) const { typedef typename result< const this_type(ContextT) >::type result_type; result_type strm = phoenix::eval(m_left, ctx); strm << m_right; return strm; } }; template< typename LeftExprT > inline phoenix::actor< output_terminal< phoenix::actor< LeftExprT > > > operator<< (phoenix::actor< LeftExprT > const& left, argument const& right) { phoenix::actor< output_terminal< phoenix::actor< LeftExprT > > > res = { output_terminal< phoenix::actor< LeftExprT > >(left, right.m_value) }; return res; } typedef phoenix::expression::argument< 1 >::type stream_type; const stream_type stream = {}; } // namespace my int main(int, char*[]) { function< void (std::ostream&) > func; func = my::operator<< (my::stream, my::argument("Hello, world!")); func(std::cout); return 0; } I also have specialized phoenix::result_of::is_nullary, phoenix::is_custom_terminal and phoenix::custom_terminal based on the _is_my_terminal tag. The problem is that the code doesn't compile. The compiler output is quite lengthy and it ends in this: ./boost/fusion/adapted/struct/detail/at_impl.hpp:24:16: error: invalid use of incomplete type ‘struct boost::fusion::extension::access::struct_member<boost::phoenix::vector1<const boost::phoenix::actor<boost::proto::exprns_::expr<boost::proto::tagns_::tag::terminal, boost::proto::argsns_::term<my::output_terminal<boost::phoenix::actor<boost::proto::exprns_::basic_expr<boost::proto::tagns_::tag::terminal, boost::proto::argsns_::term<boost::phoenix::argument<1> >, 0l> > > >, 0l> >*>, 1>’ It is not clear where the problem is but I think for some reason Boost.Phoenix thinks that output_terminal is a nullary terminal, despite the fact that I specialized is_nullary to return false. Is there something wrong with my code or is it a problem with Boost.Phoenix? I have posted the complete code here: http://pastebin.com/Vniq1b5Y and here is the compiler output: http://pastebin.com/8Beg4LiY I'm using release SVN branch and GCC 4.6. Thanks in advance.

[rational] Over/underflow checked update ready for comments
by Dan Searles 25 Aug '12

25 Aug '12

For those interested in rational, there is an updated version in https://svn.boost.org/svn/boost/sandbox/rational ready for comments. Quick overview of the update: the original usage and code of the template class remains mostly as before, ie boost::rational<int> RationalVar; should work as in the original version. Adding 'true' as a second template parameter, however, allows an exception to be raised if an operation with a class variable results in a value that can't accurately be represented, ie boost::rational<int,true> RationalVarChecked. Checking is only needed on limited precision integer types, and it has been tested with signed char, short, int and long long. Thank you for your constructive comments. Dan Searles

attempting sandbox svg_plot templates
by Roger Martin 25 Aug '12

25 Aug '12

Hi, Thought svg_plot (https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization/) is an interesting approach. Trying to stand it up and test it's implementation status. Using gcc 4.7 on Windows 7, Ubuntu 12.04 and CentOS 5. all 64 bit. Run into many template and friend issues. Anybody getting this lib to work? Much coming from https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization/boost/svg_pl…. First two: .............. In file included from ../../testing-grounds/divcon-support_libs/local/r.linux-x86_64.gcc-shared/include/boost/svg_plot/svg_2d_plot.hpp:32:0, from tests/plotting_tests.cpp:21: ../../testing-grounds/divcon-support_libs/local/r.linux-x86_64.gcc-shared/include/boost/svg_plot/uncertain.hpp:241:11: required from here ../../testing-grounds/divcon-support_libs/local/r.linux-x86_64.gcc-shared/include/boost/svg_plot/uncertain.hpp:97:24: error: template-id ‘operator<< <>’ for ‘std::ostream& boost::svg::operator<<(std::ostream&, const boost::svg::unc<false>&)’ does not match any template declaration ../../testing-grounds/divcon-support_libs/local/r.linux-x86_64.gcc-shared/include/boost/svg_plot/uncertain.hpp:102:24: error: template-id ‘operator<< <>’ for ‘std::ostream& boost::svg::operator<<(std::ostream&, const std::pair<boost::svg::unc<false>, boost::svg::unc<false> >&)’ does not match any template declaration .............. for the code: .............. friend std::ostream& operator<< <> (std::ostream& os, const unc<correlated>& u); /*! Output a pair of (X and Y) values with (if defined) uncertainty and degrees of freedom. \details For example: "1.23 +/- 0.01 (13), 3.45 +/- 0.06 (78)". */ friend std::ostream& operator<< <> (std::ostream& os, const std::pair<unc, unc>& u); ............... Seems to be where std::ostream is being extended or derived from. But I'm not discerning the template error or good at interpreting them. How to learn? Been looking for examples and where the gcc version makes a difference but get too many hits with google.

Re: [boost] What to do with platform defining 'null' as preprocessor symbol?

Boost doesn't avoid "min" and "max" but encloses them in parentheses to prevent preprocessor expansion. "null" could be treated similarly, though some may prefer to choose a different identifier. (At least there isn't an algorithm named "null"!) You'll need to find all the places where "null" occurs and file Trac tickets to get things fixed. If you supply patches against trunk, they are more likely to be applied. If you can apply the patches and run the tests yourself against several compilers on different platforms, you could send a summary reply to this thread with the Trac issues and the results of your testing. Then, someone might even submit all of your patches in one go. _____ Rob Stewart robert.stewart(a)sig.com Software Engineer using std::disclaimer; Dev Tools & Components Susquehanna International Group, LLP http://www.sig.com ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.

Sequence Printer (usually part or all of a container) using type_erasure
by Paul A. Bristow 24 Aug '12

24 Aug '12

With the recent acceptance of type erasure as a Boost library, I have continued experiments with the sequence printer provided as an example by Steven Watanbe. This seems to me to have very general usefulness, providing a way of safely, neatly and painlessly printing the contents of a container of any type. To give a flavour of what can be done, given some items in a container, one can print the whole container: double da[] = {1., 2., 3., 4., 5., 6., 7., 8., 9., 10., 11., 12. }; decor_printer line_printer; // Using all decor_printer defaults. line_printer.print(da, std::cout); // "1 2 3 4 5 6 7 8 9 10 11 12" // Prints all on one line, space separator and newline at the end. Instead of providing several printer types (as Steven did), I have concentrated just one printer class decor_printer derived from his abstract printer. But I have added to it several constructor parameters to control the number of columns, the width of the columns, and string to prefix, separate, suffix and final terminator. // Construct a printer for 3 ragged columns, and comma as separator. decor_printer plain_printer(3, 0, "\n", ", ", "\n", "\n"); plain_printer.print(da, std::cout); which outputs: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 We can also apply this to std::vector (and all the other STL container types) and a more complex type like quantity<length, measurement<double> > (where there is a measurement value and estimate of its uncertainty (+/-). // Array of Boost.Units quantity with an uncertain type. quantity<length, measurement<double> > q[] = { measurement<double>(45210.0, 1234.0) * meters, measurement<double>(765.3, 2.5) * meters, measurement<double>(12.34, 12.5) * meters, measurement<double>(5.67, 2.5) * meters, measurement<double>(0.789, 2.7e-2) * meters, measurement<double>(7890, 2.5e-2) * meters, measurement<double>(5.78e-4, 2.5e-4) * meters, measurement<double>(765.3, 2.5) * meters, measurement<double>(0.0789, 2.7e-4) * meters, measurement<double>(7890, 2.5e-1) * meters, measurement<double>(5.78e-7, 2.5e-8) * meters, measurement<double>(76.3, 2.5) * meters, measurement<double>(53.8e6, 2.34e5) * meters }; To list this neatly we may need a column width of 25. decor_ printer fancy_printer(4, 25, "\n", ", ", "\n"); // 4 columns, 25 char wide fancy_printer.print(q, std::cout); which outputs: 45.21(+/-1.234) km, 765.3(+/-2.5) m, 12.34(+/-12.5) m, 5.67(+/-2.5) m, 789(+/-27) mm, 7.89(+/-2.5e-005) km, 578(+/-250) um, 765.3(+/-2.5) m, 78.9(+/-0.27) mm, 7.89(+/-0.00025) km, 578(+/-25) nm, 76.3(+/-2.5) m, 53.8(+/-0.234) Mm (Unless the email destroys the layout L ) Note the cool autoprefixing of quantities so the units change from m to km, mm, Mm as appropriate. Finally, the parameter to the printer is a *range*, so *part* of any container can nearly as easily be printed. Does anyone share my enthusiasm for this? Paul PS I have also re-ordered the abstract_printer parameters in the hope of providing std::cout as default, so one can write just line_printer.print(da); // "1 2 3 4 5 6" But so far I can't get it to find the charT and traits parameters, despite providing defaults. Two files attached (and need the sandbox version of type erase library. Can anyone more expert get this to work? --- Paul A.

[config] NO_USER_DEFINED_LITERALS ?
by Matus Chochlik 24 Aug '12

24 Aug '12

Hello, does Boost.Config provide some macro for the detection of (un)availability of user-defined literals (N2765) ? I could not find any in the docs for 1.51.0 nor by grepping in the boost/config/* files. If not, would there be a big problem adding it (called for example BOOST_NO_USER_DEFINED_LITERALS), please ? Thanks in advance, Best regards, Matus

Equivalent of "bootstrap.sh --without-libraries" for Modularized and CMake-ified boost
by Julien Woillez 24 Aug '12

24 Aug '12

Dear boost(a)lists.boost.org, I'm trying to use CMake to build boost, using its Modularized and CMake-ified version at: https://github.com/ryppl/boost-zero I need to do the equivalent of --without-libraries=mpi with bootstrap.sh. Any idea if this is possible, and if so how to do it? Regards, -Julien
