[xpressive] wide character blank not matching properly
by Jean-Francois Bastien 29 Jun '07

29 Jun '07

It seems that xpressive's blank isn't matched properly to a space when used with wide strings. Here is a short example: #include <boost/xpressive/xpressive_static.hpp> #include <string> #include <iostream> #if 1 // 1 for wide character, 0 for normal. # define REGEX_TYPE boost::xpressive::wsregex # define REGEX_ITER_TYPE boost::xpressive::wsregex_iterator # define REGEX_MATCH_TYPE boost::xpressive::wsmatch # define STR_TYPE std::wstring # define STREAM_TYPE std::wcout # define STR(s) L##s #else # define REGEX_TYPE boost::xpressive::sregex # define REGEX_ITER_TYPE boost::xpressive::sregex_iterator # define REGEX_MATCH_TYPE boost::xpressive::smatch # define STR_TYPE std::string # define STREAM_TYPE std::cout # define STR(s) s #endif int main() { using namespace boost::xpressive; REGEX_TYPE expr = ( s1= ( STR("something") >> +( (*blank >> +alpha) ) ) ) ; STR_TYPE strings[] = { STR("something"), STR("something "), STR("somethingelse"), STR("something else") }; const int numStrings(sizeof(strings) / sizeof(strings[0])); for(int i(0); numStrings != i; ++i) { const STR_TYPE & s(strings[i]); STREAM_TYPE << "String \"" << s << "\":" << std::endl; for(REGEX_ITER_TYPE current(s.begin(), s.end(), expr), end; current != end; ++current) { const REGEX_MATCH_TYPE & what(*current); const STR_TYPE match(what[1]); STREAM_TYPE << "\t" << match << std::endl; } } return 0; } I would expect the last string to match (as it does with simple characters) but it doesn't. Using space instead, or using (set= STR(' '),STR('\t')) seems to work in both cases. I'm using MSVC 2005 SP1. I'm not sure if the problem is in the compiler's char traits and how blank uses them (if it does) or somewhere in the bowels of xpressive. Thanks, JF

[serialization] dynamically_initialized
by Nikolay Mladenov 29 Jun '07

29 Jun '07

Hi Robert, What is the reason for having both dynamically_initialized::instance and dynamically_initialized::get_instance ? The reason I am asking is because my program is crashing and I tracked it down to dynamically_initialized::instance being used to before it is initialized with dynamically_initialized::get_instance. It a compiler bug, but it seems to me it can be worked around by removing dynamically_initialized::instance . I am compiling with msvc8.sp1 Regards, Nikolay Mladenov

[unordered] Status, incompatible with Interprocess
by Aaron W. LaFramboise 29 Jun '07

29 Jun '07

The 18.03.2007 20:42 upload of unordered.tar.gz in the vault, which as far as I know is the most recent copy of the proposed Boost unordered containers library, is no longer compatible with Ion Gaztañaga's Boost Interprocess. See <http://lists.boost.org/boost-users/2007/06/28971.php> for the details of this change. Other than this recent change, I can report that the unordered containers seem to work fine with Interprocess. What is the status of the unordered containers library? I don't see it listed on the review schedule. Is it planned to be submitted for formal review any time soon?

Any interest in an "opaque iterator" library?
by lists＠mr-edd.co.uk 29 Jun '07

29 Jun '07

Hi folks, I've been working on an "opaque iterator" library that is designed to do for iterators what the pimpl idiom does for classes in general. A motivating example and some experimental code can be found here: http://www.mr-edd.co.uk/?p=36 Before I take it further I'd like to know if there's any interest in having such a library within the boost collection so I can start refactoring it in the rough direction needed for formal review. Thanks, Edd

Re: [boost] I'd like to write a static lambda library.
by Alexander Nasonov 29 Jun '07

29 Jun '07

I couldn't find out quickly if you're applying BOOST_TYPEOF to passed lambda expression but if you do, it would blow up your computer if compiler doesn't support native typeof (Hint: try passing -DBOOST_TYPEOF_COMPLIANT to compiler's arguments). Have you considered something like int (*static_fun)(int const&, int const&) = (_1 + _2 + 3).get_static_function(1, 2); get_static_function does not necessarily accept values, it may have a different interface: (_1 + _2 + 3).get_static_function<int const&, int const&>(); (_1 + _2 + 3).get_static_function(mpl::vector<int const&, int const&>()); Does your idea help to improve performance and/or reduce size of program that has a lot of conversions from lambda expressions to tr1::function? 26.06.07, 17:31, Atry <pop.atry(a)gmail.com>: > I wrote a intial version, I have tested it on cygwin ported gcc 3.4.4 and > msvc 7.1, for more infomation, see README and tests in zip packet in vault. > http://boost-consulting.com/vault/index.php?direction=0&order=&directory=Ge… > On 6/25/07, Atry <pop.atry(a)gmail.com> wrote: -- Alexander Nasonov

[smart_ptr] marking shared_ptr_move_test known failure
by Boris Gubenko 28 Jun '07

28 Jun '07

smart_ptr library test shared_ptr_move_test assumes the compiler support for rvalue references. The only platform participating in HEAD testing it compiles on is gcc-4.3.0_c++0x. I'd like to mark this test known failure for all the platforms in HEAD where it fails to compile because of the lack of the compiler support for rvalue references. Any objections? Thanks, Boris

[Property Tree] registry parser bug
by Johan Råde 28 Jun '07

28 Jun '07

boost::property_tree::read_registry does not handle registry keys that contain periods correctly. Example: When I run the following code boost::property_tree::ptree pt; string key = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32"; boost::property_tree::read_registry(HKEY_LOCAL_MACHINE, key, pt); boost::property_tree::write_xml("Drivers32.xml", pt); I get the output below. But there is no registry key "msacm". There are registry keys "msacm.imaadpcm", "msacm.msadpcm" etc. --Johan Råde <?xml version="1.0" encoding="utf-8"?> ... <\values> ... <msacm> <imaadpcm>imaadp32.acm</imaadpcm> <msadpcm>msadp32.acm</msadpcm> <msg711>msg711.acm</msg711> <msgsm610>msgsm32.acm</msgsm610> <trspch>tssoft32.acm</trspch> <msg723>msg723.acm</msg723> <msaudio1>msaud32.acm</msaudio1> <sl_anet>sl_anet.acm</sl_anet> <iac2>C:\WINDOWS\system32\iac25_32.ax</iac2> <l3acm>C:\WINDOWS\system32\l3codeca.acm</l3acm> </msacm> ... </\values> <\types> ... <msacm> <imaadpcm>1</imaadpcm> <msadpcm>1</msadpcm> <msg711>1</msg711> <msgsm610>1</msgsm610> <trspch>1</trspch> <msg723>1</msg723> <msaudio1>1</msaudio1> <sl_anet>1</sl_anet> <iac2>1</iac2> <l3acm>1</l3acm> </msacm> .... </\types>
