xpressive and white space skipping
by Jorge Lodos Vigil 29 Nov '07

29 Nov '07

Hi We are using xpressive with a grammar to match certain patterns. In some cases, we have the need to ignore white spaces. Using dynamic regexes, this can be achieved with the ignore_white_space constant. Is there a way to ignore white spaces using a grammar in xpressive other than modifying the grammar itself? We know spirit is an option, but we need to evaluate parsing speed with as many methods as possible. Thanks in advance. Cheers Jorge

Is there any interest in a casting library where you don't need to specify a type of receiver?
by Sergey Shandar 29 Nov '07

29 Nov '07

Hello all I have my own C++ framework (http://cbear.berlios.de, SVN: http://tools.assembla.com/svn/cbear/trunk/) which has some useful (IMHO) libraries. One of this library is "cast" library (http://tools.assembla.com/cbear/browser/trunk/cbear.berlios.de/cast) which allows you to convert objects without specifying a type: char c; int i; ... // if(c == static_cast<char>(i)) if(c == cast::static_::value(i)) { ... } It is useful when you want to convert an object to a type of another object. And this is also more safe, compare to standard casting, for example in previous code someone can change the type of c to wchar_t, and if you use static_cast, the compiler will not even warn you about incorrect casting. So, you have to manually check all the code. Currently there are several castings: static, reinterpret, const, dynamic, polymorphic (based on Boost.polymorphic_cast), polymorphic_down (based on Boost.polymorphic_downcast), explicit (calls an explicit constructor), safe_reinterpret (compare sizes of converting types), default (returns an object created by default constructor). Thank you. Best regards, Sergey Shandar.

[dataflow] version 0.8.1: runtime reflection, dataflow network modeling via BGL...
by Stjepan Rajko 29 Nov '07

29 Nov '07

Hello everyone, I have uploaded a new version of the dataflow library to the vault (in the Dataflow directory), and updated the docs at: http://dancinghacker.com/code/dataflow/ The new version introduces the Dataflow.Blueprint layer, which provides runtime reflection of components/ports, as well as modeling and analysis of dataflow networks via BGL. This new layer is still full of hacks, its documentation is limited to a messy example, but I'm excited about having started it. This version also has some documentation updates and some additional examples (such as a little image processing dataflow example using Boost.GIL). If anyone is interested, my roadmap to requesting review looks like this: * add lots and lots of docs. * bring the Dataflow.Blueprint to some reasonably usable state. * move functionality from the overabused Port-related concepts into the Component concept, which should clean up and simplify the concepts dramatically. With this, I think the library will be in decent shape to request a review (it will have one dataflow framework modeling the generic concepts - Dataflow.Signals, and one layer built on top of the concepts, - Dataflow.Blueprint). My goal is to get there in the next month (which is only 5 months after GSoC close! :-)) By the time it actually gets to be reviewed, I hope to also add in another dataflow framework that would in some way address the things currently missing from this library (there are many). Any feedback is appreciated. Thanks to Phil Endecott, Pavel Vozenilek, John Torjo, Roland Schwarz and Neal Becker for their helpful feedback on the previous version. Regards, Stjepan

[iterator] pure_traversal in zip_iterator?
by shunsuke 28 Nov '07

28 Nov '07

Hi, See this example, which doesn't compile for now: #include <list> #include <string> #include <boost/tuple/tuple.hpp> #include <boost/iterator/zip_iterator.hpp> #include <boost/iterator/transform_iterator.hpp> int to_value(int const &v) { return v; } int main() { std::list<int> rng1; std::string rng2; boost::make_zip_iterator( boost::make_tuple( boost::make_transform_iterator(rng1.begin(), &to_value), // BidirectionalInput rng2.begin() // RandomAccess ) ); } This incurs an error: boost::detail::error_not_related_by_convertibility<T1,T2>' : base class undefined with T1=boost::detail::iterator_category_with_traversal<std::input_iterator_tag,boost::bidirectional_traversal_tag>, T2=boost::random_access_traversal_tag in minimum_traversal_category_in_iterator_tuple. template<typename IteratorTuple> struct minimum_traversal_category_in_iterator_tuple { typedef typename tuple_impl_specific::tuple_meta_transform< IteratorTuple , iterator_traversal<> // !!!!! >::type tuple_of_traversal_tags; // ... }; Couldn't "iterator_pure_traversal<>" be used instead of `iterator_traversal<>` here? The iterator_pure_traversal<> could be something like this: template< class Iterator = mpl::_1 > struct iterator_pure_traversal : boost::detail::pure_traversal_tag< typename boost::iterator_traversal<Iterator>::type > { }; Once Category is turned into pure one, the above example compiles. Is there any pitfalls if Category is "purified"? Regards, -- Shunsuke Sogame

Policy: "preferred" method of reporting bugs
by David Abrahams 28 Nov '07

28 Nov '07

http://boost.org/more/bugs.htm still says that the preferred way to report bugs is to send an email message. Do we really mean that? It's way more reliable to open a Trac ticket. Is there any reason not to change the "preferred" approach? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

discrepancy between multi_array and its documentation
by Shawn D. Pautz 28 Nov '07

28 Nov '07

I believe that I have found a discrepancy between multi_array and its online documentation. In the reference manual at http://boost.org/libs/multi_array/doc/reference.html both the copy constructor and the assignment operator are described as calling the copy constructor of the stored type (element). No mention is made of the assignment operator of element. But in the implementation it appears that both functions call element's assignment operator (via calls to std::copy or boost::detail::multi_array::copy_n). Furthermore the multi_array assignment operator does not call element's copy constructor at all. Here is a simple program to illustrate the behavior: >more ./testMultiArray.cc #include <boost/multi_array.hpp> #include <iostream> using std::cout; using std::endl; class Foo { public: Foo() { cout << " Foo default constructor" << endl; } Foo& operator=(const Foo& foo) { cout << " Foo operator=" << endl; return *this; } Foo(const Foo& foo) { cout << " Foo copy constructor" << endl; } }; int main() { cout << "Calling multi_array extents constructor" << endl; boost::multi_array<Foo, 1> myFooArray(boost::extents[2]); cout << "\n\nCalling multi_array copy constructor" << endl; boost::multi_array<Foo, 1> myFooArray2(myFooArray); cout << "\n\nCalling multi_array assignment operator" << endl; myFooArray2 = myFooArray; } Here are the runtime results (compiled with gcc 3.4.5 against Boost 1.34.1): >./testMultiArray Calling multi_array extents constructor Foo default constructor Foo copy constructor Foo copy constructor Calling multi_array copy constructor Foo default constructor Foo copy constructor Foo copy constructor Foo operator= Foo operator= Calling multi_array assignment operator Foo operator= Foo operator= What are the intended requirements on the stored type? Does it need to be Assignable? The above example works since Foo is Assignable, but for other types (such as nested multi_arrays) the multi_array copy constructor will not work. Could someone either fix multi_array or update the documentation? Shawn Pautz

ASIO: Why does do_one use a one second timeout and loop whan called in blocking mode?
by James Talbut 28 Nov '07

28 Nov '07

The implementation of do_one in win_iocp_io_service.hpp causes the waiting thread to wakeup every second, but I can't see any reason for doing so. The wakeup causes unnecessary context switches, which could have an impact on a busy machine, so what is the reasoning behind them? Thanks.

What's the problem? could you help? thanks! -- ------------------------------- Enjoy life! Barco You
