Can we use SVG (Scalable Vector graphics) for HTML Boost docs?
by Paul A. Bristow 19 Feb '12

19 Feb '12

In adding new functions and distributions to Boost.Math, I've become dissatisfied with diagrams and equations using PNG. They are either large and/or fuzzy :-( And they get fuzzier if you expand them :-(( All browsers now support native display of SVG (Scalable Vector graphics) quite well *except* older versions of Microsoft Internet Explorer (IE9 displays SVG OK). So we are still producing HTML versions of the Boost.Math docs using embedded PNG equations and diagrams. So everyone has to endure poor quality diagrams and equations, just so that a few MS IE<9 users can see the diagrams. 1 I'd like to have views on when we can disregard the Luddites and use SVG throughout? We'd also like to use MathML to display equations, saving authors a lot of effort and much reduced file sizes. All current versions of browsers *except Microsoft IE - even IE9* also support MathML. 2 I'd like views on using MathML - with the downside that all IE users would not see equations displayed? (Everyone can view the PDF version - which uses SVG, so displays nicely even when magnified). Thank you. Paul --- Paul A.

[release, heap] bug fix merge request
by Tim Blechmann 18 Feb '12

18 Feb '12

i'd like to ask permission to merge one trivial fix for boost.heap from trunk into release [1]. it fixes an error that was reported on the boost-user list yesterday. i know it is pretty late, but as boost.heap is a new library it won't introduce a regression ... thanks, tim [1] https://github.com/ryppl/boost- svn/commit/65e619ffba40d3f2243cb235a906d4d75d9651c1

[graph] about subgraph
by Ernest Galbrun 18 Feb '12

18 Feb '12

Hello all, I would like to share my thoughts about the subgraph facility provided in the graph library. I have dived in it during the past few days because it looked nice, and it seemed to do what I was willing to do (that is, being able to work on various parts of the root graph while maintaining useful invariant). However, I have stumbled on surprising difficulties (I mean I would not have anticipated them from a boost component) : - The subgraph does not support serialization. In my opinion, it is a key feature for any kind of container. I found a broken version on the web and (as far as I can tell) fixed it, but it still seems to me that it is lacking from the original component. - The copy constructor is broken (see https://svn.boost.org/trac/boost/ticket/6564 but I see my comment on the second necessary patch was not sent, the bottom line is the original copy constructor led to errors when working on the copied graph). It is a central function, the fact that it has been broken without anyone but me noticing thus far leads me to think that a/ I am even less competent than I think I am in programming or b/ not many people use subgraph. - The remove_vertex is not implemented, and will not be (see https://svn.boost.org/trac/boost/ticket/4752 ). I was again very surprised when I discovered that, it was really an obvious function, the kind that justify for me the use of subgraph. And, reading further on the commentary for that "wont fix bug", the suggestion from jewillco of using a filtered_graph instead is perfectly relevant for my case. Nevertheless, I would rather have read such suggestion on the doc before chosing my component than at this quite late point. So I have one question and one suggestion to you boost (graph (subgraph)) developers : - Don't you think, given the lack of tests/users and the the missing features, that subgraph should leave the library ? - I think, if it stays, that the documentation should emphasize these points, and especially the last point : that filtered_graph is often a better solution. As a final note, I feel a little bit out of my place since I have absolutely no legitimacy criticizing the work of people who are by far more competent than me in computer sciences, so I won't feel offended if you point out that I am totally wrong. sincerey yours, -- Ernest Galbrun

Move semantics for std::string?
by Robert Dailey 17 Feb '12

17 Feb '12

I'm using C++03 and would love some way to apply move semantics to a std::string. Can boost facilitate this in some way without using smart pointers? Consider an example like below (This is a contrived example, so assume NRVO does not apply): std::string GetInformation( int someNumber ) { // We use 'someNumber' to look up a string std::string myValue( "hello world" ); // Create the string here return myValue; } Above, the return value would result in a copy, I'd like to move it instead. --------- Robert Dailey

RFC: runtime-flexible arrays
by Bjoern Andres 17 Feb '12

17 Feb '12

Hi everyone, I have written a header for runtime-flexible multi-dimensional views and arrays and would love to get comments and feedback from the boost community: tutorial code : http://tinyurl.com/7hdldc9 main website : http://www.andres.sc/marray.html doxygen reference doc: http://www.andres.sc/marray/doc/index.html git repository : https://github.com/bjoern-andres/marray tech report : http://arxiv.org/pdf/1008.2909v1 Unlike in Boost.MultiArray, the dimension of arrays is not a template parameter in Marray. Other features include - runtime-flexible dimension, shape, size and indexing order (first or last coordinate major order) - arithmetic operators with automatic type promotion and expression templates. - access to entries via coordinates, scalar indices and STL-compliant random access iterators. - derived classes for matrices and vectors - support of exchangeable STL-compliant allocators. Thanks for your consideration Bjoern

Can't build boost 1.48 with STLport 5.2.1
by Robert Dailey 17 Feb '12

17 Feb '12

I'm trying to get Boost 1.48 building using STLport 5.2.1. I am on Windows 7 x64. Here is what I've done: 1. Update tools/build/v2/user-config.jam with the following: using msvc : 7.1 ; using stlport : 5.2.1 : C:/Code/third_party_source/STLport-5.2.1/stlport : C:/Code/third_party_source/STLport-5.2.1/lib ; 2. Run the following command through the VS2003 command line tool: bootstrap.bat 3. This sets up the b2 executable and stuff, after that I run: b2 toolset=msvc link=shared threading=multi runtime-link=shared variant=debug stdlib=stlport --layout=tagged stage However, once it comes time to link the first library (boost filesystem), I get a ton of linker errors, mostly LNK2001 relating to unresolved STLport symbols. Here is one of the first ones: path.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall stlpd _std::basic_string<wchar_t,class stlpd_std::char_traits<wchar_t>,class stlpd_std::allocator<wchar_t> >::basic_string<wchar_t,class stlpd_std::char_traits<wchar_t>,class stlpd_std::allocator<wchar_t> > (class stlpd_std::basic_string<wchar_t,class stlpd_std::char_traits<wchar_t>,class stlpd_std::alloca tor<wchar_t> > const &)" (__imp_??0?$basic_string@_WV?$char_traits@ _W@stlpd_std@@V?$allocator@_W@2@@ stlpd_std@@QAE@ABV01@@Z) Anyone have any idea how I can get this working? --------- Robert Dailey

Boost.Asio documentation needs to be updated
by Bernd Prager 17 Feb '12

17 Feb '12

All, The documentation states that Boost.Asio requires __USE_W32_SOCKETS must be defined when using Cygwin. That doesn't seem to be true any longer. When I define __USE_W32_SOCKETS compilation of several components (e.g. ./boost/test/impl/debug.ipp) fail with "error: '::select' has not been declared". Without that definition compilation works apparently fine. Regards, -- Bernd

[exception] warning about non-virtual destructor - resolution?
by Nathan Ridge 16 Feb '12

16 Feb '12

Hello, GCC 4.7 introduces a new warning [1] that warns about calling "delete" on a pointer of a type that has virtual functions but a nonvirtual destructor. This warning is enabled with -Wall. As a result, even something as trivial as the following: #include <boost/thread/future.hpp> when compiled with -Wall, produces a warning like this: In file included from boost/boost/smart_ptr/shared_ptr.hpp:30:0, from boost/boost/shared_ptr.hpp:17, from boost/boost/date_time/time_clock.hpp:17, from boost/boost/thread/thread_time.hpp:9, from boost/boost/thread/future.hpp:13, from Source/timetable.cpp:1: boost/boost/checked_delete.hpp: In instantiation of 'void boost::checked_delete(T*) [with T = boost::error_info<boost::tag_original_exception_type, const std::type_info*>]': boost/boost/smart_ptr/detail/shared_count.hpp:95:13: required from 'boost::detail::shared_count::shared_count(Y*) [with Y = boost::error_info<boost::tag_original_exception_type, const std::type_info*>]' boost/boost/smart_ptr/shared_ptr.hpp:177:50: required from 'boost::shared_ptr<T>::shared_ptr(Y*) [with Y = boost::error_info<boost::tag_original_exception_type, const std::type_info*>; T = boost::error_info<boost::tag_original_exception_type, const std::type_info*>]' boost/boost/exception/info.hpp:171:69: required from 'const E& boost::exception_detail::set_info(const E&, const boost::error_info<Tag, T>&) [with E = boost::unknown_exception; Tag = boost::tag_original_exception_type; T = const std::type_info*]' boost/boost/exception/info.hpp:192:46: required from 'typename boost::enable_if<boost::exception_detail::derives_boost_exception<E>, const E&>::type boost::operator<<(const E&, const boost::error_info<Tag, T>&) [with E = boost::unknown_exception; Tag = boost::tag_original_exception_type; T = const std::type_info*; typename boost::enable_if<boost::exception_detail::derives_boost_exception<E>, const E&>::type = const boost::unknown_exception&]' boost/boost/exception/detail/exception_ptr.hpp:182:13: required from 'void boost::unknown_exception::add_original_type(const E&) [with E = std::exception]' boost/boost/exception/detail/exception_ptr.hpp:161:32: required from here boost/boost/checked_delete.hpp:34:5: warning: deleting object of polymorphic class type 'boost::error_info<boost::tag_original_exception_type, const std::type_info*>' which has non-virtual destructor might cause undefined behaviour [-Wdelete-non-virtual-dtor] Note that the same code compiled without warnings with GCC 4.6. I've read this thread [2] about this issue, but it's not clear what the agreed-upon resolution was. In light of this new warning, can the code be revised to avoid it? Or is it the position of the library maintainers that GCC is in error to give a warning in this case, in which case I should file a GCC bug? Or is there some other recommended resolution? Thanks, Nate [1] http://gcc.gnu.org/gcc-4.7/changes.html#cxx [2] http://boost.2283326.n4.nabble.com/boost-exception-detail-error-info-base-d…

Re: [boost] [optional] generates unnessesary code for trivial types

16 Feb '12

> > FYI I'm currently working closely with Andrzej Krzemienski on a std proposal which, among other things, involves the long awaited update to the Boost implementation. > > Could you give a use case for optional<T&>. When reading the doc about I completely understand the other use cases: > * return types > * parameters > * locals > * members > * expensive unnecessary default construction > We could be having the same conversation about optional<bool>. Here the documentation is clear: it works as expected but is the user probably should be using tri-state. > We could optimize optional<bool> to store ~0 to indicate unset. I personally don't think it's worth doing that, since use case is questionable. > As far as I can tell optional<T&> is a type which can be easily confused with optional<T>, but is really equivalent to T*. It also allows for debates about the meaning of reassignment. > I'm not dead set against this optimization. I'm just wondering if anyone will really benefit and if it's worth adding a specialization + tests. Speaking for myself, I do not have a need for optional reference. I have been using Boost.Optional for many years, I find it extremely useful; and I never had a use case for optional reference. On the other hand, others seem to be in need of optional references.Andrey said in this thread that that he wants to use it. The only two motivating use cases that triggered the addition of optional references (that I am aware of) is the interface of Boost.Variant (see http://lists.boost.org/Archives/boost/2003/02/44585.php) and the use case for Boost.Spirit (see http://lists.boost.org/Archives/boost/2003/10/55584.php) I would be reluctant to just discard these use cases. On the other hand, if they are allowed, the controversy of assignment arises. One thing to note is the requirement for optional references is not motivated by optimization opportunities, but additional behavior. > Side question: is streamablity going to be in your proposal? It is not currently. The reason for that is that there is no clear way how it should be implemented (a similar issue applies to pairs, tuples, variant, any, etc...) See http://lists.boost.org/Archives/boost/2005/03/81619.php for discussion. I believe that the problem is with the streaming itself. For instance, should streaming out and then streaming the result back in produce the same value? Some people expect that, but even std::string could not provide this behavior. Regards, &rzej

Boost Graph Library - serialization of subgraph
by Ernest Galbrun 16 Feb '12

16 Feb '12

Dear fellow boost member, I am currently using the boost graph library, and especially the subgraph features. As there is no serialization feature for subgraphes, I have developped my own, by modifying the one developed by Rakuto that was broken, probably due to some changes in the graph library ( http://rakuto.blogspot.com/2008/12/c-library-for-serialazation-of.html ). If you think it would be useful, I could do the remaining work (that is thorough testing and debugging, and providing automated test case, maybe I am forgetting something ?). The bottom line is that I am new to this kind of project, and I will probably need some kind of guidance about the way to contribute. sincerely yours, -- Ernest Galbrun

how to search this list efficiently ?
by Steven Samuel Cole 16 Feb '12

16 Feb '12

i have a few questions about boost that might have been discussed and answered on this list before. there seems a convention to add the topic in square brackets to the subject as e.g. [thread], [preprocessor] or [review], etc. how do i search the list archive by these topics ? i see there is http://search.gmane.org/ but that only supports search by keywords in the entire message and seems to ignore [square brackets]. there is also custom google search on the boost homepage which i can further filter down to the mailing lists by adding site:lists.boost.org, but it also ignores square brackets, even when put in double quotes and does not seem to allow sorting by date or support a threaded display. lists.boost.org/Archives/boost/ doesn't support searching at all. is there a trick how to search the mailing list archives properly ?

[intrusive] advanced lookup/insertion suggestion
by Rei Thiessen 16 Feb '12

16 Feb '12

Something that has bothered me with the advanced lookup and insertion functions is that I have to specify the hash/equality functors at every invocation site: c.find(key,key_hash(),key_equality()); c.insert_check(key,key_hash(),key_equality(),cd); If we don't consistently use the same (key_hash,key_equality) pair for a given (element_type,key_type) pair, the container invariant will likely be broken. Thus, I think it's very un-"C++ like" to have to specify these two types at every invocation site. Assuming that we don't want to embed (key_type,key_hash,key_equality) directly into the type of a container, the library could use a type operator to automatically deduce the appropriate hash/equality functions given an element/key type pair at the find/insert member function instantiation point: // library template<typename ElementType, typename KeyType> struct element_key_info {}; // different name to avoid overload confusion. // instantiation succeeds only when // element_key_info is properly specialized template<typename KeyType> iterator unordered_set::find_key( KeyType const& k ) {...} ... // user namespace intrusive{ template<> struct element_key_info<element_type,key_type> { typedef key_hash hash_type; typedef key_equality equality_type; }; } element_type e(...); c.insert( e ); key_type k(...); ... = c.find_key( k ); These new signatures do not allow non-default-constructible hash/equality functors, but the original signatures that do are still available. I think this makes the code simpler and safer in exchange for some additional type declarations. Would this be a worthwhile addition to the intrusive associative containers?

Offering sorted_vector for Boost, any interest?
by Frank Birbacher 15 Feb '12

15 Feb '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I've come across lots of code that uses std::set where I think a sorted vector would perform better. Those places a characterized by: 1. fills the set only once, 2. just wants to drop duplicates or 3. calls set::find very often. Facing such code I often wished there was a ready to use sorted_vector implementation. I think a new container that stores elements in a vector instead of a tree offers strong advantages: a. one call to std::sort instead of managing a red-black-tree b. less memory overhead c. better data locality for lookup Possible things that I currently consider: - - offer one-time initialization read-only sorted container? - - offer mutable container with std::set-like interface (complexity changes)? - - offer taking contents from std::vector for init without copying - - offer equivalent to std::map also? - - provide a pointer container, too? Is there general interest in such a container? I'd like to develop an implementation and offer it to Boost.

Adding support for auto in Boost.Foreach
by paul Fultz 15 Feb '12

15 Feb '12

I have a macro that I use on older compiers that let's me use auto inside of a foreach loop using the typeof operator. My original implementation relies on variadiac macros, but it can be rewritten without requiring variadiac support(possibly using the new keyword facility from Lorenzo Caminiti). Here is examples of some foreach loops it would support: BOOST_FOREACH(auto x, range) {} BOOST_FOREACH(auto& x, range) {} BOOST_FOREACH(const auto& x, range) {} BOOST_FOREACH(volatile auto x, range) {} Also, on compilers that support variadiac macros, it would be nice to add support for commas in the type, such as: BOOST_FOREACH(pair<string, string> p, range) {} This would work by poping off the back of the sequence in order to get the container. Now, you could only have commas in the type and not the container, so this wouldn't work: //Won't work BOOST_FOREACH(auto x, get_some_range<A, B>()) {} However, 1) We can place parenthesis around the container, like this: BOOST_FOREACH(auto x, (get_some_range<A, B>())) {} 2) Almost 95% of the gotchas with the foreach seemed to be with using commas in the type. So ultimately, I think it would reduce the number of gotchas drastically. Is there interest in adding something like this? Or maybe just part of it? Also if there interest, what kind of process would I go through to get them submitted and reviewed? -paul

FW: Snobol4 matching in C++
by Steven Kibler 15 Feb '12

15 Feb '12

I have an implementation of Snobol4 patterns and pattern matching that runs in C++. All of the Snobol4 patterns and replacements are implemented in addition to numerous extensions that have proven useful over the years. The patterns are built with overloaded operators and building patterns is simple, straight forward, easy to read and test. In many cases, I find that Snobol4 patterns and its matching algorithm is clearer, more intuitive, and more useful than regular expressions. I have been able to typically cut the required lines of code to accomplish pattern matching by half or a third over using regular expressions. The package is well integrated into C++ and its data types. For post circa 1980 'newbies' unaware of the power of Snobol4, a description of Snobol4 can be seen in a copy of several Snobol4 manuals at ftp://ftp.snobol4.com/spitman.pdf and ftp://ftp.cs.arizona.edu/snobol/gb.pdf. I would like the package to be published under the auspices of Boost. I would like to know if this package would be something that the users of the Boost community would be interested in. This package was originally written in Ada by Robert Dewar and AdaCore, translated to C/C++ by Philip Budne, and cleaned up and expanded by me. The Philip Budne version may be found at http://www.snobol4.org/ (Look for the SPIPAT link) along with many other references for SNOBOL and SPITBOL. Thanks Steven Kibler Facet Soft Tech, Inc.
