[bimap][math][fusion][type traits][function]Missing and old generated documentation
by Daniel James 04 Feb '08

04 Feb '08

Hi, I've been building the documentation and comparing with the files that are checked in. The following files seem to be missing from subversion: libs/bimap/doc/html/boost_bimap/the_tutorial/additional_information.html libs/math/doc/sf_and_dist/html/math_toolkit/main_overview/compilers_overview.html And the following files might be obsolete now (i.e. they're in subversion but are not generated): libs/fusion/doc/html/fusion/extension/macros.html libs/type_traits/doc/html/boost_typetraits/category/background.html libs/bimap/doc/html/boost_bimap/the_tutorial/hooking_information.html Similarly, the following fowarding html files are for html documents that aren't generated, so they should probably be removed. doc/html/boost_typetraits.html doc/html/functionN.html doc/html/boost_typetraits/background.html doc/html/boost_math.html Daniel

question about flyweight
by Robert Ramey 04 Feb '08

04 Feb '08

I've spent a tiny amount of time looking over the flyweight documentation and some code and I have a couple minor observations along with a really dumb question. a) when I see boost::flyweight::flyweights it confuses me. I suppose its no big deal. b) I'm curious about the serialization implementation. Why didn't you choose just to serialize the factory? This seems to me the most obvious implementation and I wonder why you didn't feel it was a good choice. template< class Archive, typename T,typename Arg1,typename Arg2,typename Arg3 > void serialize( Archive& ar,const ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3>& f, const unsigned int version) { typedef ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3> flyweight; ar & flyweight::factory(); // serialization tracking guarentees only one copy ar & f.h; // serialization tracking optimizes down to an integer object id } This might not be a good idea if flyweight reference count isn't used. So another idea might be: template< class Archive, typename T,typename Arg1,typename Arg2,typename Arg3 > void save( Archive& ar,const ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3>& f, const unsigned int version) { typedef ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3> flyweight; ar << f.h; // serialization tracking optimizes down to an integer object id } template< class Archive, typename T,typename Arg1,typename Arg2,typename Arg3 > void load( Archive& ar,const ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3>& f, const unsigned int version) { typedef ::boost::flyweights::flyweight<T,Arg1,Arg2,Arg3> flyweight; T t; ar >> t; // serialization tracking optimizes down to an integer object id f.factory.insert(t); // or something along those lines //fix up object address of t - off hand I don't remember the syntax } In short, I don't see why a "helper" is required.

Boost-like URL handling/parsiing library?
by Marshall Clow 04 Feb '08

04 Feb '08

I am in need of a library to parse/encode/decode URLs. A quick look through the boost tree doesn't yield any obvious candidates. Before I dive into writing my own, does anyone have any pointers/recommendations? Thanks! -- -- Marshall Marshall Clow Idio Software <mailto:marshall@idio.com> A.D. 1517: Martin Luther nails his 95 Theses to the church door and is promptly moderated down to (-1, Flamebait). -- Yu Suzuki

extension / reflection project status?
by Janek Kozicki 04 Feb '08

04 Feb '08

Hello, What is the status of Boost extension / reflection library? (is this a single library or two separate?) Currently I'm mainly concerned about the "extension" part. Was it submitted for review? Or do you want to submit them both together to go in a single review, and for that you plan to first finish the "reflection" part? Because as I understand (am I right?) the extension library is quite finished and should be ready to use, eg. in my app? Can you provide some "official" URL for documentation and download? best regards, and big thanks for your hard work! -- Janek Kozicki |

[rfc] I/O Chain Library, Preview Release 2
by Sebastian Redl 04 Feb '08

04 Feb '08

Hi, I'm proud to announce preview release 2 of my I/O Chain library. Preview 1 was announced here: http://lists.boost.org/Archives/boost/2007/11/131079.php IOChains is a component-based I/O library similar to Boost.Iostreams, but built from scratch instead of being based on the C++ iostreams interface. It currently supports binary I/O of primitives only, but will be extended to cover text, too. It is built to be type-safe and fast. The main changes since Preview 1 are: Most importantly: The archive actually contains the code. :-) 1) Tested under Visual C++.Net 2003, i.e. VC++ 7.1. 2) Endian conversion is now supported. 3) Supports reading and writing fixed-point numbers. 4) Supports reading and writing stdin, stdout and stderr. (Not Win32, yet.) This also demonstrates the utility of the command interface. 5) A bit-level access pseudo-component was added. 6) A rationale section was added to the documentation. 7) A few example programs were added. (Not tested in Win32, but except for the password reader, they should work.) The code can be found at: http://stud3.tuwien.ac.at/~e0226430/iochain-preview-2.tar.bz2 <http://stud3.tuwien.ac.at/%7Ee0226430/iochain-preview-1.tar.bz2> The installation is still not trivial. Boost doesn't appear very suited to develop new libraries outside the tree, it seems. 1) Unpack the archive. 2) Make boost-build.jam point to your trunk Boost.Build, or delete the file if you already have a boost-build.jam in place. 3) Edit Jamroot: set the constant REALBOOST at the very top to point to your trunk Boost. 4) If you want to use the zlib component, add an entry to your user-config.jam for zlib. On Linux, this should be as trivial as lib zlib : : <name>z ; On Win32, it might look like this: lib zlib : : <file>"c:/path/to/zlib/zlib1.lib" : : <include>"c:/path/to/zlib" ; The documentation doesn't build due to some problems I have with Boost.Build. A pre-built version can be found here: http://stud3.tuwien.ac.at/~e0226430/iochain/ If you want to build the docs yourself, remove the <tag> requirement from Jamroot. A note about Visual C++: newer compilers than 7.1 should work, unless they exhibit this bug: http://groups.google.com/group/comp.lang.c++.moderated/browse_thread/thread… If they do, you need to grep the source for BOOST_WORKAROUND and adjust the version number. Oh, and let me know. Older versions will most definitely not work. Minor new features: 1) The content of an erasure can change. 2) Bug fixes. 3) Minor refactorings. 4) Best practice: all public implementation classes now have protected destructors. Have fun, and please tell me what you think. Sebastian Redl

[review] Review of Flyweight library started January 21 and still running!
by Ion Gaztañaga 03 Feb '08

03 Feb '08

Hi all, The formal review of Flyweight library started January 21 and will end January 30, we have a few nice reviews, but I'm sure that those who haven't reviewed it are also interested in the library ;-). The library solves quite a common programming pattern, is small and very well documented. So don't be afraid to try it! Information for reviewers: *Description:* Flyweights are small-sized handle classes granting constant access to shared common data, thus allowing for the management of large amounts of entities within reasonable memory limits. Boost.Flyweight makes it easy to use this common programming idiom by providing the class template flyweight<T>, which acts as a drop-in replacement for const T. *Online docs:* http://tinyurl.com/2sstyr http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/index.html *Download:* http://tinyurl.com/hrdm6 http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… *Notes:* 1) We've seen some suggestions in the mailing list for Flyweight. Joaquín has nicely explained a couple of issues that we'd like to address/discuss in the review: http://tinyurl.com/33ghtf http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/doc/review_… 2) Flyweight needs Boost 1.35 elements because the library depends on libraries like Interprocess for some features/tests. Since SVN snapshot tarballs seem to be missing these days, those who want to try flyweight can download a working SVN-HEAD snapshot here: http://igaztanaga.drivehq.com/boost_trunk.tar.bz2 3) Serialization tests won't work. This feature is expected to work when some new features (discussed in the mailing list between Joaquín and Robert Ramey) are added in Boost.Serialization. Those are expected for Boost 1.36. What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Ion Gaztañaga - Review Manager -

preview of a template geometry library
by Tom Brinkman 03 Feb '08

03 Feb '08

My geometry needs are fairly simple. At this point, I just need them to create simple graphic primitaves, such as coloring in polygons, determining interesection points, simplyfing lines, etc. All these things appear to be addressed in this library, so I'm looking forward to following this library progress. I've created my own versions of many of these algorithms, but more as a learning excercise and they are not very good. In any event, I would be available if you want to chat offline for some reason.

BoostCon Call for Sessions
by Jeff Garland 03 Feb '08

03 Feb '08

The second annual Boost conference will take place in Aspen, Colorado, May 5-9. BoostCon is the main face-to-face event for all things Boost, from generic-programming techniques to Boost community, from using Boost libraries to writing Boost libraries, from deployment considerations to promoting the use of Boost more widely, from TR1 to TR2. Given the range and interests of last year's participants, the event again promises to be intense and in depth. We invite you to propose a session. See the BoostCon home page at www.boostcon.com for more information. Session formats Presentations focus on a practitioner’s ideas and experience with anything relevant to Boost and Boost users. Panels feature three or four people presenting their ideas and experiences relating to Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials are formally prepared sessions at which instructors teach conference participants specific Boost-relevant skills. Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations focus on tips on usage and design. In addition, we're looking to uncover the hidden design gems hidden in boost libraries -- see below for more. Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Session topics Topics of interest include, but are not restricted to, the following: * General tutorial sessions introducing one or more Boost libraries * In-depth sessions on using specific libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * TR1 (and TR2) * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops o Build tools o Website o Testing * C++0x and how it will change life for users and library writers * Concepts and Generic Programming * Other topics likely to be of great interest to Boost users and developers Interactive and collaborative sessions are encouraged, as this is the nature of both the online Boost community and the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Author's Corner Presentations Based on user feedback from last year, we'd like to encourage Boost library authors to do short sessions (typically 30 minutes) providing an overview of their libraries, tips on usage and design. In particular, we're looking to uncover the hidden design gems that underlie so many boost libraries. Standard outline for a presentation is as follows -- feel free to deviate as needed. * Library Purpose / Motivations * Library Genesis & History o why you developed it o when it was accepted o how it has evolved * Library Concepts * Library Usage Overviews and Tips * Library Design Decisions / Design Gems * Question / Answer Submitting a proposal Standard Sessions are 90 minutes.
