generic script language binding
by Sascha Krissler 20 Dec '06

20 Dec '06

Hello, the langbinding list is abandoned, the cvs directories empty, nothing seems to be in the vault and i started the same thing (a generic langbinding library). So please tell me, is langbinding still developed or should i continue mine? PS: i had that aha moment when i realised that dispatch on all arguments can also be used for multiple dispatch within C++. That would be a nice boost library: a generic dispatcher for foreign languages and C++ itself. Right now i am finding out whether one can write an awkward-syntax-predicate- dispatcher in c++. what is the world's opinion on all this, i would like to know.

[system] - using error_code::new_category
by Oliver.Kowalke＠qimonda.com 20 Dec '06

20 Dec '06

Hello, It is not so clear for me how to use error_code::new_category. I've a library which uses two legacy libraries which have error codes (int) with the same value. How can I incorporate the error codes both libraries into boost::system? void f_calls_api_A() { int result( 0); if ( ( result = api_A_x() ) == -1) throw system_error( error_code( result, ...) ); // ? } void g_calls_api_B() { int result( 0); if ( ( result = api_B_y() ) == -1) throw system_error( error_code( result, ...) ); // ? } Void main() { try { f_calls_api_A(); g_calls_api_B(); } catch ( system_error const& e) { // how to know if it comes from A or B? } } Regards, Oliver

lcast_set_precision
by Gennadiy Rozental 20 Dec '06

20 Dec '06

Why following definitions in detail/lcast_precision.hpp doesn't cause an ambiguity with 1-2 argument calls? template<class T> inline void lcast_set_precision(std::ios_base& stream, T* = 0 ) { ... } template<class Source, class Target> inline void lcast_set_precision(std::ios_base& stream, Source* = 0, Target* = 0 ) { ... } As of now these definitions cause Boost.Test to fail build on Sun CC 5.3 compiler and I would really like it to be addressed somehow.

[Boost.Regex] Minor documentation issue
by Javier Estrada 20 Dec '06

20 Dec '06

I believe the function validate_card_format should take a const std::string& instead of a const std::string http://www.boost.org/libs/regex/doc/introduction.html bool validate_card_format(const std::string s) { static const boost::regex e("(\\d{4}[- ]){3}\\d{4}"); return regex_match(s, e); }

[thread] Proposal to add lightweight_mutex and atomic_count
by Andrey Semashev 20 Dec '06

20 Dec '06

Hello, There are "lightweight_mutex.hpp" and "atomic_count.hpp" files in the "detail" directory. I find these tools quite simple and useful in some projects where I don't want to link against the whole Boost.Thread library yet having a degree of portability. But every time I include it the nasty "detail" word in the path always makes me remember that I'm using library's internals that are not the part of public interface. Why not making these tools a part of Boost.Thread library, without any change, of course? A couple of forwarding headers in "boost/thread" and a documentation update would be a nice solution. Thank you. -- Best regards, Andrey mailto:andysem@mail.ru

If boost::fusion is the hammer, then what's the nail?
by Weapon Liu 20 Dec '06

20 Dec '06

I think this is the right place to ask this question. As cool as boost::fusion is, there's still one question that bothers me, that is, if boost::fusion is the hammer, then what's the nail? I sure know that it's generic( more so than boost::tuple) and it's complete( with a bundle of algorithms and cool utilities), and it seems that it "solves" some problem quite well( when I read the documents). However, I found it bothering that the documents didn't even mention one real-world application( boost libs aside). Based on my experience, the most frequent scenarios where boost::tuple/fusion is useful are those where one needs a generated-on-the-fly struct for holding return values bundle, or where one needs to return multiple values transparently( well, nearly so), just like those lua does. Other than that, I can't really imagine a scenario where this kinda stuff kicks butts. The biggest disadvantage of boost::fusion, I think, is that the size of it is known and fixed at compile time, which renders it not so qualified as a truly heterogeneous container. And by the bye, that it can be used to build a handy pseudo-struct that enables full introspection really is a good and fancy feature. However, there's something fundamentally irremediable of it, that is, it can't be used to build a full-fledged class( rather than a POD-struct), which, I think, will too reduce its usefulness w.r.t. this kinda situations. I personally very like this fancy facility, and that's why I present these mumbles here to annoy you guys( if so, my apologies go here:-)) Any comments?

Re: [boost] Accumulators accumulators. roc_distribution

In fact IIRC that was one of the examples. What might be a problem though is having multiple instances of the same accumulator. I was meaning to ask Eric about that but I wanted to try it first, looks you got there before me :) Matt Scanned by McAfee GroupShield {X3BTB534}
