[ICL] interval_map::find(const domain_type_comparable&) instead of interval_map::find(const domain_type&)
by Denis 23 May '11

23 May '11

Hi Joachim One small note about Icl maps. I think would be useful to make interval_map::find()'s function accept any type comparable to map's key. For example, the key type is std::string and the user want to search using a 0-terminated string or a string defined as arbitrary pointer and a length. Then the user will have to allocate the temporary string only to pass it to interval_map::find() You may argue that the std::map works same way. But there is the difference. If I want to do the trick above, I can use boost::multi_index or at least instead of std::map<std::string, ValueT> I can define something like std::map<tuple<const char*, size_t>, tuple<std::string, ValueT>> with key's const char* and size_t pointing to the data hosted in value. This is not possible with interval_map, where the values can be joined

BoostCon video mirror
by Jeroen Habraken 23 May '11

23 May '11

Hi, After becoming annoyed with blip.tv I've created a mirror of the BoostCon videos with the help of Nikhef (http://www.nikhef.nl/en/) It can be found at http://wipkip.nikhef.nl/events/BoostCon/2010/ and there's a quick overview over at http://vexocide.org/boostcon.html. If desired we'll gladly host the 2011 videos as well. Regards, Jeroen Habraken

[btree] Status report
by Beman Dawes 22 May '11

22 May '11

The slides for my BoostCon "Proposed Boost B-tree Library" presentation are available: http://github.com/boostcon/2011_presentations/raw/master/tue/proposed_b_tre… Please be aware that while the library is progressing nicely, it isn't ready for production use: * There are outstanding bugs, particularly with variable length data. * Names and signatures may still change. * Documentation is barely started. * Build is failing on Mac OS X. That probably won't get fixed until after BoostCon. (Reported by Marshall Clow) That said, the response to the presentation was very positive and I'm actively continuing development. Anyone interested in the library is encouraged to take a look and give it a try. See http://github.com/Beman/Boost-Btree/blob/master/README for install instructions. Feedback welcome! Thanks, --Beman

Boost statechart viewer
by Petr Šilhavík 20 May '11

20 May '11

Dear Boost-Statechart developers and users, I would like to ask you to try the tool that I am developing in my bachelor thesis and give me your opinion about it. The tool is able to visualize state machines that use Boost-Statechart library. It uses Clang and LLVM *(version 2.9)* for producing the output files that can be visualized using dot. Now it can work with states (not the orthogonal states), transitions and custom reactions. You can find more information about it on the web page of this project where you can also download the source codes and see some examples of the output pictures. http://rtime.felk.cvut.cz/statechart-viewer/ I am looking forward to your answers. Best regards Petr Silhavik

How to inspect state of boost::mt19937?
by Matthew Gwynne 20 May '11

20 May '11

Hi, Does anyone know how I can access the internal state of the Mersenne twister (boost::mt19937) easily? That is the 623 state bytes. I am looking to initialise a random number generator and then inspect the state to compare it to another system which apparently implements MT19937 but gives different results. If someone could point me in the right direction, that would be great! Thanks! Matthew Gwynne http://cs.swan.ac.uk/~csmg/

Generic try, catch in boost::lexical_cast
by Jeroen Habraken 20 May '11

20 May '11

Hi, Whilst updating SVN today I spotted a change to boost::lexical_cast, https://svn.boost.org/trac/boost/changeset/71958, which introduces a try { } catch(...) { } construction. I'm curious as to why this catch-all is needed since it seems to be there to deal with boost::numeric_cast exceptions and whether it could lead to a std::bad_alloc being rethrown as a bad_lexical_cast. Kind regards, Jeroen Habraken
