utf8_codecvt facet - volunteer opportuntiy
by Robert Ramey 03 Jan '13

03 Jan '13

Our implementation for a codecvt facet internal wide char to/from utf8 format requires some maintainence. We have our own implementation since 2001. Since then, the standard libary has come to specify some implementations and some libraries have implemented some or all of this aspect of the standard library. I've come to believe that we should: a) tweak our code to use the standard library implementations if they exist. b) tweak our code to use the names of the standard library implementation b) tweak our build so that our version replaces the the standard library implementation when and only when there is no standard implemenation available. This seemingly simple task is complicated by the following circumstances. a) The relationshp between UCS and Unicode is pretty confusing. b) The iterface for codecvt is confusing. c) a number of standard library implementations have non-conforming codecvt interface. d) a number of standard library implementations don't have any codecvt header at all. This is not a problem for our current implementation because we never import it. Anyone interested in working on this should contact Marshall, Beman or myself (in that precedance). Robert Ramey

[config] Proposed BOOST_NOEXCEPT_NOTHROW macro
by Beman Dawes 03 Jan '13

03 Jan '13

The three current BOOST_NOEXCEPT* macro variants miss the case where C++03 code has a "throw()" throw-specifier. Classes that derive from standard library exceptions need this to avoid breaking code on C++03 compilers. I'm not enamored with the BOOST_NOEXCEPT_NOTHROW name, so feel free to offer suggestions for alternate names. Here is the full set of macros: #ifdef BOOST_NO_NOEXCEPT # define BOOST_NOEXCEPT # define BOOST_NOEXCEPT_NOTHROW throw() <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) # define BOOST_NOEXCEPT_EXPR(Expression) false #else # define BOOST_NOEXCEPT noexcept # define BOOST_NOEXCEPT_NOTHROW noexcept <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) noexcept((Predicate)) # define BOOST_NOEXCEPT_EXPR(Expression) noexcept((Expression)) #endif Unless there are objections, I'll commit the changes Wednesday afternoon Eastern US time. --Beman

[xpressive] Broken in release if explicit operator bool is available
by Andrey Semashev 03 Jan '13

03 Jan '13

Hi, With the recent change to Boost.SmartPtr that adds support for explicit operator bool() Boost.Xpressive no longer compiles. The relevant error message is: ./boost/xpressive/detail/utility/tracking_ptr.hpp:440:73: error: no type named ‘unspecified_bool_type’ in ‘class boost::intrusive_ptr<boost::xpressive::detail::regex_impl<const char*> >’ Could this be fixed?

Flow-based programming library for Boost?
by Marcus Tomlinson 03 Jan '13

03 Jan '13

Is there any interest out there for a library that allows you to create fast, efficient flow-based programs with an easy-to-use object-oriented interface? (http://en.wikipedia.org/wiki/Flow-based_programming) I've created an open-source library that does this, called "DSPatch" ( http://sourceforge.net/projects/dspatch) and would like to contribute it to the Boost Libraries. Please let me know if this sounds like something you'd like to see in Boost. Thanks!

problem with release branch serialization test results
by Robert Ramey 02 Jan '13

02 Jan '13

I recently merged the serialization library files from the trunk to the release branch. Now most of the tests on the release branch are failing. The message is: "Error extracting file: No matching files were found." Which suggested to me that I munched up the merge. But when I browse through the release branch files and log I can't see anything wrong. Would anyone have any idea what might be causing this and what I have to do to fix it? Robert Ramey

[GitHelp] odeints repository
by Karsten Ahnert 02 Jan '13

02 Jan '13

Hi, odeint has already a git repository at github (https://github.com/headmyshoulder/odeint-v2) Can this be used instead of the default boost git repository for odeint? At the moment the directory structure of this repository uses the old structure odeint odeint/boost odeint/boost/numeric/ odeint/boost/numeric/odeint odeint/libs/numeric odeint/libs/numeric/odeint odeint/libs/numeric/odeint/doc odeint/libs/numeric/odeint/test but it can easily be changed to fit to the new directory structure.

Hi, my name does not appear in the owner list of the boost components in trac. Can someone show my how to fix it? The AuthorMapping looks correct, so I do not know what is wrong here. Thank you, Karsten
