[thread] Memory usage of threads on 64bit linux
by Conrad Mercer 29 Aug '12

29 Aug '12

Hey, I have been using boost threads on 32bit linux for some time and am very happy with their performance so far. Recently the project was moved to a 64bit platform and we saw a huge increase in memory usage (from about 2.5gb to 16-17gb). I have done profiling and found that the boost threads are the source of the huge allocation. Each thread is allocating about 10x what it was doing on 32bit. I profiled using valgrind's massif and have confirmed the issue using only boost threads in a separate test application. I also tried using std::threads instead and these do not exhibit the large memory allocation issue. I am wondering if anyone else has seen this behaviour and knows what the problem is? Thanks --

[system] Viral C++11 change would break dependent libraries:-(
by Beman Dawes 28 Aug '12

28 Aug '12

Ticket #7278 asks that Boost.System add C++11 noexcept support. A reasonable request, and I implemented it this morning by adding BOOST_NOEXCEPT at the appropriate places specified in the standard. But there is a problem. noexcept is viral, so any classes that inherit from a class that uses noexcept must be changed to also use no except. An example: Boost.Filesystem has this class: class codecvt_error_cat : public boost::system::error_category { public: codecvt_error_cat(){} const char* name() const {return "codecvt";} std::string message(int ev) const; }; Compiling with GCC 4.7 -std=c++0x results in this error: ..\..\../boost/system/error_code.hpp:187:32: error: overriding 'virtual const char* boost::system::error_category::name() const noexcept (true)' To fix it, the filesystem class has to be changed: class codecvt_error_cat : public boost::system::error_category { public: codecvt_error_cat(){} const char* name() const BOOST_NOEXCEPT {return "codecvt";} std::string message(int ev) const; }; I've held off committing the Boost.System changes to trunk until we've had a chance to discuss how to approach this potential break to an unknown number of Boost and user libraries. Ideas? --Beman

[contract] Broken postconditions on throw
by Andrzej Krzemienski 28 Aug '12

28 Aug '12

Hi Lorenzo, I am now now playing with Contract library and trying to break it. I checked that the framework checks the class invariant even when member function exits via an exception. This is an expected behavior and the framework is working fine. However, I note that the precondition of a (non-member) function is not checked when the function exits via throwing an exception. See the following program: # include <contract.hpp> double get_random_weight() { return -1.0; // erroneous implementation } CONTRACT_FUNCTION ( void (set_weight)( (double&) w ) postcondition(w >= 0.0) ) { w = get_random_weight(); if (w < 0.0) throw 1; // (*) } int main() try { double w = 0.0; set_weight(w); } catch (...) { std::cerr << "CAUGHT EXCEPTION" << std::endl; } Function set_weight() is intended to assign its (output) argument with a value representing weight (in the physical sense). We guarantee that the value we set is always non-negative. The function clumsily attempts to verify the condition itself (the line with *). It signals the failure with an exception, but unfortunately fails to satisfy the postcondition. I expect that this situation should be reported as a postcondition violation. But no violation is reported, and the program successfully outputs "CAUGHT EXCEPTION". Regards, &rzej

[1.52.0] Open for merging
by Marshall Clow 28 Aug '12

28 Aug '12

The release branch (https://svn.boost.org/svn/boost/branches/release) is open for merging all stable changes from trunk, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, merging *does not* require permission from a release manager, except for new libraries.

[contract] a possible future extension
by Andrzej Krzemienski 28 Aug '12

28 Aug '12

Hi Lorenzo, This is definitely outside the scope of the review, but I was wondering whether it would be feasible for the macros in Boost.Contract to handle base class aliases, as described in this proposal: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2881.html The positive "side effect" of your framework is that it has the potential to add various missing language features. I am wondering if these aliases proposed in N2881 are worth the effort. Regards, &rzej

a (useful?) crtp trick
by pavel 28 Aug '12

28 Aug '12

hi all i post this in the hope someone finds this technique useful to make long story short, here is a snippet: template<typename t> //tag deducing util struct base_tag { typedef decltype(get_tag((t*)42)) type; }; template<typename type, typename tag = typename base_tag<type>::type> struct Base //crtp base class { friend tag get_tag(type*); //helper declaration, never defined }; template<typename type> //no mention of tag void f(const Base<type>&) //tag is deduced automatically {} struct Foo : Base<Foo, void> //derived type {}; int main() { Foo foo; f(foo); } the idea is that if we have an associated type (or types) along with the "real" type in the crtp pattern we can make that associated type deduced automatically and even pretend there is no such tag leaving it e.g. for advanced usage more on this here: http://programmizm.sourceforge.net/blog/2012/because-we-can -- Pavel P.S. if you notice a grammar mistake or weird phrasing in my message please point it out

[atomic] lockfree failure on msvc 64-bit
by Christoph Macheiner 27 Aug '12

27 Aug '12

As indicated by http://www.boost.org/development/tests/trunk/developer/output/cm_x64-boost-…. In boost/atomic/detail/interlocked.hpp, BOOST_ATOMIC_LLONG_LOCK_FREE must be defined to 2 if _WIN64 is defined (cas64strong.hpp is included afterwards). Because the library has not yet been released, I didn't bother to create a ticket and because the change is so trivial I didn't create a patch as well (if either or both is required or wanted, please let me know). Question: If I recall correctly, long long can be made lockfree also in 32-bit. If I am right, is there a reason why it hasn't been done? Thanks. --Christoph.

memory corruption in async_read_until using asio::ssl
by Jim Page 27 Aug '12

27 Aug '12

Afternoon All I am seeing an occasional memory corruption bug, using valgrind, in our web server application that is using boost::asio::ssl, and it seems to be related to calls to async_read_until, where several chunks of data are required before the terminating regex is found. What appears to be happening is that engine::perform() causes a write (via ssl3_read_bytes()) on a deleted memory region, the buffer into which decrypted data is written. This region was delete'd via invocation of the detail::io_op::handler, and in turn via read_until_delim_op::operator(), due to prepare() being called on the streambuf, and a std::vector<char> is delete'd in order to create a larger one. It seems like one of the chain of handlers is using a pointer which is becomes invalid when the streambuff is expanded after failing to find the regex terminator after one or more reads, and prepare() is called before the next async_read_some() on the underlying stream. I have included the valgrind output at the end - sorry for the large size. I am pretty certain that I have ruled out the obvious (multiple simultaneous attempts to read using the same streambuf), and I am only using one thread for the io_service. This seems a pretty common potential failure mode, so perhaps I am barking up the wrong tree - I'd appreciate anyone's opinion before I start a potentially tricky debug effort requiring modification to the boost libraries on our production servers. I'm using boost 1.49. There's a lot of optimization on the application which is why some calls are optimized out of the valgrind dump. The machines are running Centos 5.8, x86_64. Compiler is gcc 4.4.6.

Boost.Process 0.5 released
by Boris Schaeling 27 Aug '12

27 Aug '12

Boost.Process 0.5 has been released! Documentation and library can be found at: <http://www.highscore.de/boost/process0.5/> Why version 0.5? We have no official process management library in Boost yet. But we had countless drafts since 2006. In order not to get completely lost between all those drafts I gave them version numbers. For example, 0.1 was the very first draft in 2006. 0.31 is the draft documented at <http://www.highscore.de/cpp/process/>. And 0.4 was the draft which was rejected in a formal review in spring 2011. Version 0.5 is the latest attempt to create a process management library. What's new? Version 0.5 has a very different design than all other drafts before. The design was proposed by Jeff Flinn who introduced it briefly at BoostCon 2011 when we gave a presentation on Boost.Process. The goals of this new version are: * A lightweight implementation (no overly complicated code anymore). * A fully extensible library (no need for arbitrary "extension points"). * Support for system-level cross-platform concepts only (no Java-like constructs). Other goals like making the library easy to use were of course also targeted. But these were goals before. The goals above are important as those things have been criticized in earlier drafts and were as far as I see the main reasons why version 0.4 had been rejected. What now? Please have a look at the documentation and think about whether this library could fit into Boost. If you have more time, please download and play around with the new version. Concentrate on the bigger picture: Does the design make sense? Is it easy to understand? Can you do what you want to do? Does it look and feel like modern C++? This is not a formal review. But it would help to get some feedback to see a tendency. After six years, two Google Summer of Code projects, countless drafts and still a lot of interest from many people in a process management library in Boost, we might be able to get somewhere this time. (If you are on Windows: There is a bug in Boost.Iostreams which has been fixed in the release candidate 1 of Boost 1.51.0. See the documentation if you run into a problem when closing pipes.) Anything missing? We had a closed beta test in the previous two weeks with about ten people who had contacted me because of their interest in Boost.Process. I got already some good feedback and have to change a few details. These are only details though and shouldn't stop anyone from using this new version now. If everyone is happy with the overall design and architecture and it's only details we have to discuss, it's already a huge step forward. Last but not least: Boost.Process 0.5 wouldn't exist without the help of Intra2net AG (<http://www.intra2net.com/>). Intra2net AG sponsored a project to support the development of Boost.Process. It was this sponsorship which made it possible to create this new version. Thanks to them! Boris

[contract] "Duplicated globals" problem
by Andrzej Krzemienski 26 Aug '12

26 Aug '12

Hi Lorenzo, I think that installing broken contract handlers will not work correctly when a program is linking with DLLs on Windows. I do not know how dynamic linking works on Linux. Here is a sketch of a sample program that fails to work as expected. The program consists of two projects: one builds a DLL, the other builds an executable that links with the DLL: DLL: ==================================== # include <contract.hpp> # include "testdll.h" CONTRACT_FUNCTION ( int (give1) () postcondition(auto result = return, result == 1) ) { return 2; // obviously wrong } DLL_MODE void test_contracts() { int i = give1(); } ==================================== EXE: ==================================== # include <contract.hpp> # include "../testdll/testdll.h" void PostconditionHandler( contract::from const& context ) { std::cerr << "ERROR!!!" << std::endl; } int main() { contract::set_postcondition_broken(&PostconditionHandler); test_contracts(); } ==================================== I expect that the program would use the broken postcondition handler I installed, but it still uses the default one. The cause is that Contract is using some global object to store the installed handler, but when a program is linked with a DLL both the program and the DLL store their own copy of the global. The global is duplicated. THe one in the EXE registers my callback, but the global in the DLL still keeps the default handler. The only way to solve this issue is to -- at least in the cases when users' programs link with DLLs -- ship Contract with a small DLL that stores the unique copy of the globals. This is how Boost.Log handles this problem. Quoting the documentation ( http://boost-log.sourceforge.net/libs/log/doc/html/log/installation.html) *"If your application consists of more than one module (e.g. an exe and one or several dll's) that use Boost.Log, the library must be built as a shared object. If you have a single executable, you may build the library as a static library." * Regards, &rzej* *

complex acos and atanh
by Stephen Montgomery-Smith 26 Aug '12

26 Aug '12

Hey people, I was trying out your complex arc-trig functions, to compare them with some that I have written: http://people.freebsd.org/~stephen/catrig.c. I am finding that your acos function is getting some of them wrong. For example, your program evaluates acos(1.00000002785941 + I*5.72464869028403e-200) as 0 - I*0.000236048349018331 whereas it should be 2.42520172707401e-196 - I*0.000236048349018331. Also your complex atanh function does quite badly in some edge cases. I presume it is because Hull, Fairgrieve and Tang did not write a paper on that function. If you email Fairgrieve, he may give you a copy of the paper that was never published. He sent me a copy, but doesn't want it widely distributed. I devised my own algorithm at http://people.freebsd.org/~stephen/catrig.c, which actually turns out to be very similar to the unpublished algorithm of Hull, Fairgrieve and Tang. Anyway, I would be happy to work with whomever is currently working on these algorithms. I think someone must be, because I see that someone fixed a bug in asin since 1.48.0. Best regards, Stephen

[locale] Custom Gettext paths.
by Jookia 26 Aug '12

26 Aug '12

Hello! I'm extremely happy about Boost.Locale, but I've found a few things lacking. So at first I wrote a some wrappers to get around a few flaws with my usage of Boost.Locale. One of these flaws was how it's hardcoded to use the Gettext directory hierarchy. I'd rather store my stuff in 'lang/en_US.mo' rather than 'lang/en_US/LC_MESSAGES/my_app.mo'. The patch adds a 'path format' feature, which allows you to format the directory structure when finding Gettext catalogs, to achieve the effect above. All you really have to do is run: gen.add_path_format("{1}/{2}.mo"); // Use a smaller hierarchy. to achieve the result that I prefer, or gen.add_path_format("{1}/{2}/{3}/{4}.mo"); // Use a Gettext hierarchy. to achieve the result that Boost.Locale uses right now. Ripped straight from Doxygen comments: {1} A path to search for catalogs in. {2} The locale's name. {3} The locale's category. {4} The Gettext domain. I'm new to submitting patches and things, and I'm not sure how I could make this feature better or even acceptable if it isn't already, but I'm sure it'd help others out there. There are a few drawbacks I've found with my code: - To be backwards compatible I've had to add some hackery to add the Gettext format if the path formats vector is empty. - Without consulting documentation, the format is unreadable. - I haven't tested it on the Win32 backend. I'm 90% sure the code would work, it's only 4 lines of code added and it's identical to the code added in the other backends, but it's still untested code. - It's not tested properly. By properly, I mean the tests past with adding a format, and falling back to the default format, but I haven't tried having a 'compact' format. I'm not sure if this would indicate a fault in the formatting code though, as that'd be the only difference code-wise, unless there's more code that has the Gettext hierarchy hardcoded, that didn't fail when I didn't fix the tests. The patch itself is based off of SVN r80097, and despite the diff being for r80104 I haven't tested it in that.. I did the work internally in Git but I made the patch using SVN, in case that matters. I've attached the patch, but I'm not sure how well that's going to go over considering I'm new to mailing lists, and I'm using.. Thunderbird.. Yeah. In case the attachment fails, it's available at http://sprunge.us/VSiX . I'd also like to know if it's appropriate to put '[patch]' in the title for any future patches, and if it should go after '[locale]' or at the end of the title. Thanks, Jookia.

boost::filesystem -- using non-POSIX locale crashes on Solaris
by JonathonS 26 Aug '12

26 Aug '12

Hi, I am currently using boost::filesystem::path on Solaris, and I noticed that if I set the locale to anything except "C" or "POSIX" such as "en_US.UTF-8", that it crashes i.e. a run-time error gets thrown. I found a link describing the issue here: https://svn.boost.org/trac/boost/ticket/5928 My question is though, whether it is possible to use boost::filesystem without locales? Meaning, if I know my string is a UTF-8 string, is it possible to avoid the locale processing within the boost filesystem? Thanks, J

Everyone who takes the time to look at the library is qualified to vote, and every vote is valuable. - Other questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? (*) Well, OK, the review period officially started yesterday.

[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?

[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
