Re: [boost] size() type
by Olaf van der Spek 18 Mar '12

18 Mar '12

Hi, Any progress on these tickets? Would be nice to have a solution. size() return type should be size_type, not difference_type: https://svn.boost.org/trac/boost/ticket/5971 data() for iterator_range: https://svn.boost.org/trac/boost/ticket/5930 Greetings, -- Olaf

I'm wondering about Beman Dawes 'Moving Boost to Git' on C++ Now! - has boost an official git-repo? Could I use it instead of svn-trunk? regards, Oliver

Hi All, Would it be possible to apply the patch I have just submitted to trac on bug 5993 ? It should be pretty harmless. https://svn.boost.org/trac/boost/ticket/5993 Many thanks, Julien

GSoC Proposal
by Subrata Biswas 18 Mar '12

18 Mar '12

Dear Sir/Madam, I want to design a new IPC for Linux(Which can be extended for windows and mac also) as a project in Google Summer of Code. I have already started it and developed its very basic prototype. I have also written the proposal according to your format. But I could not find the email id where I can send my proposal. I have used your irc but hardly anyone were available there. Can u kindly provide me the links where I can send my project proposal and direcly interact with the mentors. I hope my "Smart IPC" may enrich the smart boost c++ libraries towards smarter c++ libraries. -- Thanking You, Regards Subrata Biswas MTech (pursuing) Computer Science and Engineering Indian Institute of Technology, Roorkee Mob: +91 7417474559

C++ Now! Conference Program Highlights C++11
by Jon Kalb 17 Mar '12

17 Mar '12

C++ Now! (formerly BoostCon) is pleased to announce its 2012 program with 35+ inspiring C++ practitioners delivering more than fifty technical sessions. In honor of the release of the new C++11 standard, this May's conference will, for the first time, be offered in three tracks. In addition to the sessions that attendees have come to expecton topics like library design and usage, programming techniques, best practices, academic research, development tools, concurrency, reliability, and performancethis year's program includes a full track devoted to C++11 <http://cppnow.org/locations/c11/> and three keynotes by industry luminaries <http://cppnow.org/overview/> . For those eager to get on board with the new standard, the C++11 content features fifteen hours of tutorial material covering the most important new features and APIs, presented, in many cases, by the language designers themselves. C++ Now! is offering the most complete C++11 tutorial coverage of any conference this year! Conference speakers include book and library authors, academics, C++ Standard Committee members, tool builders, architects, and engineers. With our very high presenter-to-audience ratio, attendees will have ample opportunity for one-on-one interaction with leaders who are currently defining the state of the art in C++. Dave Abrahams, the conference co-chair, writes, "We planned for an expansion, but even I am surprised at the presenter response and the resulting depth of this year's program. I'm preparing for a flood of new attendees." Reserve your place today at http://cppnow.org/registration C++ Now! 2012, held May 13-18 in Aspen Colorado is hosted by Boost in cooperation with ACM. * Complete program: http://cppnow.org/schedule * Speakers: http://cppnow.org/participants * Registration: http://cppnow.org/registration Jon

[format] Mistake in documentation
by Yakov Galka 17 Mar '12

17 Mar '12

The current documentation ( http://www.boost.org/doc/libs/1_49_0/libs/format/doc/format.html) says: "In the Open-group specification, referring to the same argument several times (e.g. *"%1$d %1$d"*) has undefined behaviour." Perhaps it was right some time ago, but it's not longer true. The Open-group specification ( http://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html) explicitly allows this: "In format strings containing the "%*n*$" form of conversion specification, numbered arguments in the argument list can be referenced from the format string as many times as required." Thank you, -- Yakov

has_member_fnc?
by Neal Becker 17 Mar '12

17 Mar '12

It seems c++11 has a new way to spell enable_if, and this can be used to implement has_member_fnc, as in this example: http://pastebin.com/mH2cZ4NP I wonder if has_member_fnc would be a good addition to boost?

[range] adaptors and member functions pointers
by Yanchenko Maxim 17 Mar '12

17 Mar '12

Hi, While transforming and filtering sequences, it's pretty common to call the elements' member functions, so I think it's worth adding some syntactic sugar for range adaptors in order to achieve cleaner syntax. E.g. if we have a class struct Foo { std::string description() const; }; and we want to get all non-empty descriptions, we could just write this clean code: foo_list | transformed(&Foo::description) | filtered(&std::string::size) To enable this syntax, the attached patch should be applied to boost/range/adaptor/argument_fwd.hpp (diff against 1.47.0). Is there any interest to add this to Boost.Range? Thanks, Maxim

[thread] Jamfile issue
by Emil Dotchevski 16 Mar '12

16 Mar '12

Hello, In my own Jamfile targets, if I refer to Boost Thread as: alias thread : $(boost)//thread ; I get: error: No best alternative for boost_1_48_0/libs/thread/build/thread_sources next alternative: required properties: <threadapi>win32 <threading>multi not matched next alternative: required properties: <threadapi>pthread <threading>multi not matched I could do this instead: alias thread : $(boost)//thread/<threadapi>win32 ; But that clumsy, I'd be dispatching between POSIX and WIN32 configurations, which ideally should be done internally by Boost Thread's Jamfile. Is there a better way to refer to Boost Thread? Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
