[context/coroutine] split into two libs in trunk?!
by Oliver Kowalke 14 Apr '12

14 Apr '12

Hi, unfortunetly Giovanni decided to discontinue its boost.coroutine library and I was ask be several members of the boost community to provide a coroutine implementation using boost.context. I've refactored class context from lib boost.context so that I can provide coroutine<> and generator<> (following Giovannis interface proposal) based on context now. I'd like to split it into two libraries: - boost.context provides only context jumping facility (a.g. struct fcontext_t, start_fcontext()/jump_fcontext()/make_fcontext() and stack helper) - boost.coroutine contains coroutine<> and generator<> Might this be appropriate? regards, Oliver -- NEU: FreePhone 3-fach-Flat mit kostenlosem Smartphone!

[quickbook] controlling table of contents
by lcaminiti 14 Apr '12

14 Apr '12

Hello all, Is there a way for more fine control of QuickBook table of contents (toc)? Specifically, I'd like to: 1) Have a toc in the first page with only the sections (no subsections) listed. 2) Then, have a full toc on the second documentation page with all sections and subsections listed. I can use any rev of QuickBook for this. Thanks a lot. --Lorenzo -- View this message in context: http://boost.2283326.n4.nabble.com/boost-quickbook-controlling-table-of-con… Sent from the Boost - Dev mailing list archive at Nabble.com.

Hi, folks! In emulation mode, given the following definition: template <typename Container> struct some_metafunction { typedef BOOST_TYPEOF_TPL( Container().insert( typename Container::iterator() , typename Container::value_type() ) ) type; }; Which of the following types need to be registered? 1. The argument passed as `Container` 2. The result of `typename Container::iterator` 3. The result of `typename Container::value_type`

[preprocessor] badly formed constant expression on Sun

review request for boost.coroutine
by Oliver Kowalke 13 Apr '12

13 Apr '12

Hello John, hello Ronald, could you add boost.coroutine to the review queue please. boost.coroutine is a implementation of coroutines and generators using boost.context and providing an interface similiar to Giovannis coroutine library (unfortunately discontinued). code is available from gitorious : http://gitorious.org/boost-dev/boost-dev (branch coroutine) zip : http://gitorious.org/boost-dev/boost-dev/archive-tarball/coroutine documentation : <updated later - I'm searching for webspace > thanks an best regards, Oliver

Hi, I need to open fixture file (e.g. the one that contains initial data for testing) in a BOOST_AUTO_TEST_CASE. Could you please tell: * Whether it's possible? * If possible, than what is the most preferable way to do it? JFYI: We need to have something like python django fixtures.

[lexical_cast] char types and UDTs
by Eric Niebler 13 Apr '12

13 Apr '12

Say I have a wide-character, user-defined, streamable type like boost::wssub_match from the regex library (or now std::wssub_match). It's basically a pair of wstring iterators. It's stream insertion operator is defined like this: template <class charT, class ST, class BiIter> basic_ostream<charT, ST>& operator<<(basic_ostream<charT, ST>& os, const sub_match<BiIter>& m) { return (os << m.str()); } If it's not obvious, it requires that the stream's character type is the same as the BiIter's value_type. If I were to try to use boost::lexical_cast to cast this to something, it won't work. That's because lexical_cast doesn't know about wssub_match, and so doesn't know that its character type should be wchar_t. Instead, it defaults to char for any unknown types, and doesn't give a way to override this. There is an internal trait, boost::detail::stream_char, that lexical_cast uses to determine what the character type of the source is (if any). It's specialized on only a fixed number of types. Since it's an implementation detail, it can't be used to extend the set of types. Also, I tried specializing it. In past versions of Boost that just worked, but it doesn't anymore. I think being able to extend lexical_cast to support types like (std|boost)::wssub_match is an essential feature. Thoughts on how to get there from here? -- Eric Niebler BoostPro Computing http://www.boostpro.com

[lockfree] tagged_ptr as a separate library
by Philipp Moeller 12 Apr '12

12 Apr '12

In the review of lockfree it has been suggested that tagged_ptr should make it into the public API of lockfree. Wouldn't it make sense to move it into a separate library entirely? It would possibly get more exposure and cross-platform ports. The technique itself also requires some extra documentation. And it might find it's way into a release earlier than lock-free itself.

Refactoring a library for header-only or linked library?
by Paul A. Bristow 12 Apr '12

12 Apr '12

I am considering refactoring a (potential Boost) library separating declarations and definitions into two sets of files with the objective of reducing compilation times and allow it to be used as header-only or linking with a pre-built library. Is there is best/Boost way of doing this? Is there a Boost library that I should use as a model? ASIO? Should I call the definition files .cpp or .ipp? Should definition files go in libs/src or in boost/? How should I control the header-only/library switch? View and suggestions? Thanks Paul --- Paul A.
