Hi, the boost license (http://www.boost.org/LICENSE_1_0.txt) does not allow redistributing modified versions. Is that intentional or an oversight? -- Falk

Boost 1.32.0 released
by Aleksey Gurtovoy 23 Nov '04

23 Nov '04

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + NOTE: This is a stripped-down copy of the Boost 1.32.0 release + + notes. See http://www.boost.org for the full version. + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Important - New Toolset Names ----------------------------- The names of some the Boost.Build toolsets have been changed to remove the "." (dot) character and to fix some other naming inconsistencies. For example, vc7.1 toolset was renamed to become vc-7_1. Please refer to the Supported Toolsets section of the installation guide for the complete list of the current toolset names. This change was made as a part of the effort to make the Boost distribution compatible with ISO 9660 level 2 requirements. New Libraries ------------- * Assignment Library: Filling containers with constant or generated data has never been easier, from Thorsten Ottosen. * Minmax Library: Standard library extensions for simultaneous min/max and min/max element computations, from Herv Brnnimann. * Multi-index Containers Library: Containers with multiple STL-compatible access interfaces, from Joaqun M Lpez Muoz. * Numeric Conversion Library: Optimized policy-based numeric conversions, from Fernando Cacciola. * Program Options Library: Access to configuration data given on command line, in config files and other sources, from Vladimir Prus. * Range Library: A new infrastructure for generic algorithms that builds on top of the new iterator concepts, from Thorsten Ottosen. * Serialization Library: Serialization/de-serialization of arbitrary C++ data structures to various formats including text, binary, and xml, from Robert Ramey. * String Algorithms Library: Collection of string related algorithms for case conversion, trimming, find/replace operations and more, from Pavol Droba. * Tribool: 3-state boolean type library, from Doug Gregor. Updated Libraries ----------------- * Compose: This deprecated library has been removed. * Graph: - Added bundled properties to the adjacency_list and adjacency_matrix class templates, greatly simplifying the introduction of internal vertex and edge properties. - The LEDA graph adaptors have been ported to LEDA 4.5. - Added algorithms for betweenness centrality and betweenness centrality clustering. - Added circle layout and undirected spring layout algorithms. * MPL Library: - Updated to use the Boost Software License. - New documentation, including a complete reference manual. - Major interface changes and improvements, many of which are not backward compatible. Please refer to the 1.32 changelog for the detailed information about upgrading to the new version. * Python Library: - Updated to use the Boost Software License. - A new, better method of wrapping classes with virtual functions has been implemented. - Support for the new Python Bool type, thanks to Daniel Holth. - Support for upcoming GCC symbol export control features have been folded in, thanks to Niall Douglas. - Improved support for std::auto_ptr-like types. - Components used by other libraries have been moved out of python/detail and into boost/detail to improve dependency relationships. - Miscellaneous bug fixes and compiler workarounds. * Signals Library: Introduced deterministic slot ordering, permitting slots to be connected at the beginning or end of slot groups or the slot list itself. Combiners may safely have state and are accessible from the signal. * Utility: class template result_of added. * Test Library: - namespace names gets shorten; old one still supported till next release. - added proper encoding of XML PCDATA. - support for wide string comparison implemented. For complete list of changes see Test Library release notes. Regression tests ----------------- This release has been extensively tested on a variety of different compilers and platforms. It is known to contain no regressions against the previous reference release on the compilers and configurations tested. Please refer to the corresponding regression reports at http://www.meta-comm.com/engineering/boost-regression/1_32_0 to see how well your compiler performs on the new Boost codebase. Acknowledgements ---------------- This release wouldn't have been possible without the dedicated effort of many, many members of the Boost community who generously contributed their outstanding expertise, time and energy to making it happen. For patches, bug fixes, troubleshooting, expert advice, and prompt responses to the release manager's requests we thank: David Abrahams, Misha Bergal, Jonathan Brandmeyer, Fernando Cacciola, Marshall Clow, Christopher Currie, Pavol Droba, Caleb Epstein, Eric Friedman, Jeff Garland, Michael Glassford, Doug Gregor, Joel de Guzman, Hubert Holin, Jaakko Jrvi, Hartmut Kaiser, Bronek Kozicki, Tarjei Knapstad, Toon Knapen, Aaron W.

Wagner Jr. and Martin Wille. Also, our special thanks go to: John Maddock for the managing the effort of converting the majority of the Boost libraries to the Boost Software License, Eric Niebler and Joel de Guzman for taking on the important job of improving the Boost documentation's look and feel, and last, but not least, to our regression test runners, without whom we simply would never have released: Toon Knapen, Bronek Kozicki, Rene Rivera, Markus Schpflin, Stefan Slapeta, Victor A. Wagner Jr. and Martin Wille. Thank you everybody! -- Aleksey Gurtovoy MetaCommunications Engineering

[date-time] small interface nitpick
by Pavol Droba 23 Nov '04

23 Nov '04

Hi, I have spoted another small inconsistence in the date-time interface. Generic date_time::time_duration 4-parameter contructor have a default values for seconds and fractional seconds. Posix variant have default value only for frac_seconds. Regards, Pavol

date_time request for addition
by Pavol Droba 23 Nov '04

23 Nov '04

Hi, In the Date-Time library, date_duration class provides a set of basic arithmetic operations. Among others there is multiplication and division. Current interface supports only integer factors. Sometimes this precision is not sufficient. I have actualy came accross such a occasion. I need to adjust the duration using a multiplier from range <0,1>. Currenly it is not feasible, and I have to workaroud it by converting to microseconds and back. Would it be possible to alter the interface, so it will be able to use real factors? Thanks. Regards, Pavol

MPL documentation
by Edward Diener 23 Nov '04

23 Nov '04

The MPL documentation is better than before and the reference is excellent. However I do not believe the tutorial is adequate for bringing new programmers interested in understanding metaprogramming using MPL into a general understanding of how MPL works and how to use it. This is because the tutorial does not start at the beginning of defining MPL concepts but jumps into high order metafunctions without explaining the basis of metafunctions or metaprogramming classes to begin with. I understand the problem, that metaprogramming is a large concept and that understanding the basics would entail starting at a point where explaining anything further takes up much more space than a mere tutorial would normally encompass. The answer no doubt is to buy Mr. Abrahams and Mr. Gurtovoy's book. However despite the good intent of the tutorial, I think that it only performs the function of bringing further knowledge of the MPL library to those who already understand how the basics of the library already work. For those C++ programmers who want to learn to understand how to use the MPL library from scratch, I do not think the tutorial is adequate. Perhaps MPL was never meant to appeal to those without a knowledge of its precepts to begin with, but by assuming that I think that the tutorial will either leave C++ programmers who would like to learn to use MPL feeling pretty cold about it, or force them to buy the book in order to understand how it works.

result_of?
by Brock Peabody 23 Nov '04

23 Nov '04

I replaced my home grown result_type<> with boost::result_of<> today only to find that I couldn't get it to work. When I try to use result_of with VC 7.1: struct test_struct { typedef int result_type; }; boost::result_of<test_struct>::type i = 5; I get: test.cpp(10) : error C2027: use of undefined type 'boost::result_of<F>' I get the same results if I use function types of pointer to function types: boost::result_of<int (*)()>::type i = 5; boost::result_of<int ()()>::type i = 5; Am I missing something? Thanks, Brock Peabody
