iterator_adaptor: underlying iterator type?
by Aleksey Gurtovoy 20 May '05

20 May '05

Currently 'iterator_adaptor' exposes its underlying iterator _object_ (through 'base()'), but not its type, which stands in the way of a generic code manipilating adapted iterators/sequences, e.g.: template< typename Sequence > mtn::iterator_range< typename Sequence::iterator::base_type > // ^^^^^^^^^^^ // currently unavailable base_view( Sequence& seq ) { return mtn::make_iterator_range( seq.begin().base() , seq.end().base() ); } Any objections if I add the typedef (and update the docs correspondingly)? -- Aleksey Gurtovoy MetaCommunications Engineering

Tuples: how to get rid off the open/closing characters??
by Oliver Kullmann 20 May '05

20 May '05

Hello, looking into the code, the documentation, and the proposed standard I can't find a way to output a boost::tuple to a stream with no opening and closing characters??? tuples::tuple_open requires a character, and thus one has to use some opening character, and equally some closing character???? (I can't believe this: Everybody knows that adding strings is much easier than erasing them.) Oliver

[regex] match_partial and regex_search
by Eric Niebler 20 May '05

20 May '05

I noticed some surprising behavior with match_partial and regex_search. Consider: regex e("abc|b"); string str("ab"); smatch what; if(regex_search(str, what, e, match_default | match_partial)) { cout << (what[0].matched ? "full" : "partial") << '\n'; } This code displays "partial". Clearly, regex_search is bombing out just as soon as it finds a match, partial or otherwise. But in this case, if it kept looking, it would find a full match. My understanding is that full matches are always preferred to partial matches. I couldn't find any discussion about this case in the regex docs or the std proposal. Did I miss it? What's the intention here? Is the std proposal underspecified? -- Eric Niebler Boost Consulting www.boost-consulting.com

[random] Update for better TR1 compliance
by Jens Maurer 20 May '05

20 May '05

I've checked in changes to the Boost.Random library that add constructors and seeding for both template<class Generator> and unsigned long arguments, thereby moving Boost.Random one step further towards TR1 compliance. The random_test.cpp program now has basic tests for this feature. In order to guide overload resolution, I've used boost::enable_if<> and type traits to make sure that integral arguments don't try to call the "template<class Generator>" overloads. This could mean decreased compiler support, sorry. It works for me with gcc 3.4.3. Jens Maurer

Interest in C function pointer utility?
by Rene Rivera 20 May '05

20 May '05

In rewriting a plugin interface I use, which for language portability uses C function pointers as the entry points, I came up with a "make_c_function" utility. I use it to translate C++ functions, any of objects, binds, function, members, et. to _real_ C function pointers. For example: class P { public: int foo(int); }; P p; extern "C" { void * get_plugin_call(int n) { if (1 == n) { return make_c_function<P,int(int)>( boost::bind(&p,p::foo,_1)); } else { return 0; } } } [example much abbreviated from real life use] -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org

RE: Non-intrusive serialization with VC2003 (7.1) and building from CVS
by Marcin Tustin 20 May '05

20 May '05

It looks a lot like the problem I was having was caused by constness. To be clear, I was doing: template<class Archive> void serialize(Archive & ar, const Jrs::SmartPtr<D2::Message>& g, const unsigned int version) { //... } Now I'm doing: template<class Archive> void serialize(Archive & ar, Jrs::SmartPtr<D2::Message>& g, const unsigned int version) { // ... } The new version does compile, but as I am having problems building boost (from CVS), it doesn't link because the libraries don't exist. It compiles with the CVS version, but still does not compile under 1.32. As to building, I am trying to use the version of bjam I built to build 1.32, running it from the place it was built to: mt@penfold /cygdrive/c/new_boost/boost $ /cygdrive/c/boost_1_32_0/tools/build/jam_src/bin.ntx86/bjam.exe But this cannot create files or directories. Any suggestions?

[serialization][ptr_container] serialization of ptr_containers
by Felipe Magno de Almeida 20 May '05

20 May '05

Hi, I was trying to serialiaze ptr_containers and I couldnt find a way, so I copied some headers and modified them to serialize ptr_list(the only one I need to serialize in the moment), and it seems to be working. So If someone is interested, I could send it to someone. Im not an expert in the serialize library, so I dont even know if it is really right... But it worked to me(the objects are all serialized as pointers, so if there's two objects then it just serialize one...). I think that extending it to serialize others sequence containers would be very easy, but I didnt touch in the associative containers... The files that I created: ptr_collections_load_imp.hpp // from collections_load_imp.hpp ptr_collections_save_imp.hpp // from collections_save_imp.hpp ptr_list.hpp // from list.hpp Thank you. -- Felipe Magno de Almeida UIN: 2113442 email: felipe.m.almeida+spam at gmail com felipe.almeida+spam at ic unicamp br, felipe.m.almeida at gmail com, felipe+spam at synergy com (Remove the +spam from the email) I am a C, modern C++, MFC, ODBC, Windows Services, MAPI developer from synergy, and Computer Science student from State University of Campinas(UNICAMP).
