[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.

[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.

[svn/git/hg] Support for modularization of Boost?
by Beman Dawes 11 Apr '12

11 Apr '12

As far as I can see, scaling Boost up to a much larger number of libraries implies decentralization and decoupling, probably in the form of per-library modules or something similar. Modularization seems to have been missed in the discussions of Subversion, Git, and Mercurial. Do distributed version control systems in general and Git in particular have any important advantages/disadvantages over svn for highly modularized projects? Please, let's not waste everyone's time with a rehash of general DCVS vs CCVS pros and cons. We have beat that to death. Let's focus this thread on modularization support, particularly as it applies to Boost. Thanks, --Beman

[range] adaptors vs. rvalue to lvalue& binding
by Arno Schödl 11 Apr '12

11 Apr '12

Hello, ideally I would like to use range-adapted lvalue ranges like any other lvalue ranges. Writing it down naively, as below, does not compile because LoadRefRange takes (and should take?) the range it modifies by lvalue&, while adaptor expressions are rvalues. template<typename Range> void modifies_range( Range& rng ); A a[5]; main() { // modifies all elements of a modifies_range ( a ); // modifies all elements (except for one) of a // adaptor is rvalue, does not compile: modifies_range ( boost::range::join( boost::adaptors::slice( a, 0, 1 ), boost::adaptors::slice( a, 2, countof(a) ) ) ); // compiles, but ugly: auto rng=boost::range::join( boost::adaptors::slice( a, 0, 1 ), boost::adaptors::slice( a, 2, countof(a) ) ); modifies_range(rng); } Any thoughts? Should adaptors receiving lvalues offer an operator adaptor&() &&; // overload on rvalue-ness so they are passing through the lvalue or their argument? A suitable baseclass a la boost::additive could do that.

[function] why do I function1 for type-of emulation?
by lcaminiti 10 Apr '12

10 Apr '12

Hello all, I was trying to use Boost.Function together with Boost.Typeof. It seems that if I run in type-of emulation mode I have to register boost::functionN instead of boost::function even if I only use boost::function... do you know why? For example: #include <boost/function.hpp> #include <boost/typeof/typeof.hpp> #include BOOST_TYPEOF_INCREMENT_REGISTRATION_GROUP() //BOOST_TYPEOF_REGISTER_TEMPLATE(boost::function, 1) // (1) BOOST_TYPEOF_REGISTER_TEMPLATE(boost::function1, 2) // (2) int main() { typedef BOOST_TYPEOF(&boost::function<int (int)>::operator()) f; return 0; } In order to compile this (on MSVC 8.0 and GCC 4.5.3) with BOOST_TYPEOF_EMULATION #defined, I have to register boost::function1 as in line (2) but I'd expect it to work with the registration of boost::function of line (1) instead. Why do I have to register boost::function1 (2) instead of boost::function (1) for type-of emulation?

[Review Request] Multiprecision Arithmetic Library
by John Maddock 10 Apr '12

10 Apr '12

Folks, I'd like to ask for a formal review of the Multiprecision Arithmetic Library, currently in the sandbox. Features: * Expression template enabled front end. * Support for Integer, Rational and Floating Point types. Supported Integer backends: * GMP. * Libtommath. * cpp_int. cpp_int is an all C++ Boost licensed backend, supports both arbitrary precision types (with Allocator support), and signed and unsigned fixed precision types (with no memory allocation). There are also some integer specific functions - for Miller Rabin testing, bit fiddling, random numbers. Plus interoperability with Boost.Rational (though that loses the expression template frontend). Supported Rational Backends: * GMP * libtommath * cpp_int (as above) Supported Floating point backends: * GMP * MPFR * cpp_dec_float cpp_dec_float is an all C++ Boost licensed type, adapted from Christopher Kormanyos' e_float code (published in TOMS last year). All the floating point types, have full std lib support (cos sin exp, pow etc), as well as full interoperability with Boost.Math. There's nothing in principal to prevent extension to complex numbers and interval arithmetic types (plus any other number types I've forgotten!), but I've run out of energy for now ;-) Code is in the sandbox under /big_number/. Docs can be viewed online here: http://svn.boost.org/svn/boost/sandbox/big_number/libs/multiprecision/doc/h… And of course, I'm looking for a review manager ;-) Many thanks, John.

[config] unexpected explicit operators conversion on some compilers.
by Vicente J. Botet Escriba 10 Apr '12

10 Apr '12

Hi, Given the following explicit bool conversion template<typename Mutex> class unique_lock { public: explicit operator bool() const BOOST_NOEXCEPT I was expecting the following code to compile fail (note the int cast) boost::unique_lock<boost::mutex> lk0; int i = int(lk0); It fails with gcc-4.7.0, but compile with gcc-4.6.2 and clang-3.0 (I have not tested yet with msvc). When BOOST_NO_EXPLICIT_CONVERSION_OPERATORS is defined I use the bool safe idiom to emulate the conversion #if defined(BOOST_NO_EXPLICIT_CONVERSION_OPERATORS) typedef void (unique_lock::*bool_type)(); operator bool_type() const BOOST_NOEXCEPT; bool operator!() const BOOST_NOEXCEPT; #else explicit operator bool() const BOOST_NOEXCEPT; #endif and in this case the compile fail as desired. Do we need a new macro to state that even if explicit operators are provide, there are some unexpected conversions that could be introduced? Best, Vicente

[scope_exit] trunk tests fail on sun compiler
by lcaminiti 09 Apr '12

09 Apr '12

Hello all, I'm trying to get ScopeExit to work on Sun. 1) First it looked like all tests fail on this compiler: http://www.boost.org/development/tests/trunk/developer/scope_exit.html 2) However, I installed Solaris Studio 12.3 on my Ubuntu 10 and it seems that I can compile ScopeExit just fine with the following" $ CC -I /usr/include/i386-linux-gnu/ -I ../../.. -DBOOST_TYPEOF_EMULATION world_seq.cpp Note that: a) Sun does not support variadic macros so only ScopeExit sequence syntax will work. b) Sun does not support native type-of so BOOST_TYPEOF_EMULATION needs to be defined. Therefore, all original ScopeExit type-of emulation tests named `emulation_...` should compile (because they use the sequence syntax and define BOOST_TYPEOF_EMULATION). However, they fail... why? 3) Why when I click on the "fail" link for these tests I get no information on the Sun compiler's output? For example: http://www.boost.org/development/tests/trunk/developer/output/Sandia-sun-bo… If I follow this link I get "Error extracting file: No matching files were found.". What does this mean?

Metaprogram benchmarks

In order to measure the compile-time efficiency of various C++11 metaprogramming techniques, I'd like to put together a set of benchmarks, and I wanted to discuss here what kinds of tests might be appropriate. Aleksey and I came up with some benchmarks for an appendix to http://boostpro.com/mplbook/, but some of those are lost and they're all getting a bit crusty. Certainly, I have no confidence that they are realistic or useful. If anyone has ideas about this, I'd be very glad to hear them.

[string_algo] ilexicographical_compare()/is_iless() bug?
by Dmitry Vinogradov 08 Apr '12

08 Apr '12

I want to share a problem using ilexicographical_compare(). I think that ilexicographical_compare() must compare two strings in "alphabetical" order, the order letters appear in alphabet. But ilexicographical_compare() uses is_iless() to compare letters. And such comparison looks like: std::toupper<T1>(Arg1,m_Loc)<std::toupper<T2>(Arg2,m_Loc); So, in fact, letters are compared depending on their position in a charset. It's not always match the alphabet order. Examples are Cyrillic letters "Io" and "i" (Unicode 0451 and 0456). I think the right solution is to compare like this: T1 Ch1 = std::toupper<T1>(Arg1,m_Loc); T2 Ch2 = std::toupper<T2>(Arg2,m_Loc); return std::use_facet< std::collate<typename CharType> > (m_Loc).compare(&Ch1, &Ch1 + 1, &Ch2, &Ch2 + 1);

leads to property and/or tree conflicts when merging your own stuff, and I can't tell you how annoying that is to figure out! :-( BTW, my sincere apologies to Eric here - he just happened to be the latest culprit - can some SVN guru suggest how to prevent this sort of spurious changing going on? BTW2, lest this turn into "my extra advanced version control system doesn't do messy stuff like this" conversation - I'm sure you're correct - some other version control system probably doesn't have this trap - but I sure bet it has other traps just as annoying for the unwary. Just saying.... Thanks, John.
