[gsoc2008] YAML archives for Boost.serialization
by Esteve Fernandez 31 Mar '08

31 Mar '08

Hi all, it seems that the period for student applications has been extended to April the 7th. Although I briefly discussed the idea for YAML archives following a message by Sohail, I would like to explain it in more detail, discuss some concerns and see if there's interest. We already talked about YAML not being a superset of JSON, however given the recent great news of the relicensing of TinyJSON, it still can be used as a basis to build YAML parser. My main concern is that YAML is sensitive to indentation, actually it uses indentation as a substitute for { block }. One can write YAML to look like JSON, use TinyJSON and everything will be fine, but it will not be able to parse documents that use spaces/tabs to delimit blocks, only those that use curly brackets. I guess it will have to be implemented at the scanner level in Boost.Spirit, but it becomes more complicated. Anyway, with more complications, comes more fun :-) I might be mistaken about where to implement this stuff so feel free to correct me, but I think it's the way to go, as I took a look at the source code for the Python interpreter and for LibYAML, and they implemented the indentation stuff in their scanner, not in the parser. The good thing about doing YAML instead of JSON is that all the concerns about object tracking and class versioning disappear, as they're already implemented in the official spec. JSPON might or not be added to the official JSON spec, although there are good chances that it will be, but it's still not officially accepted and may change in the future. Also, a parser needs to implement JSONPath (an XPath-like language for querying JSON documents), since a reference to the root object can be written as "$ref" : "$[0].child" A side advantage of implementing the YAML archives is that a C++ parser for YAML would be available for those who don't want to use the official LibYAML C parser. Anyway, what do you think? Is there interest for this project? Cheers.

No PropertyTree in 1.35.0; when will it be in an official release?
by Ryan Gallagher 31 Mar '08

31 Mar '08

Congrats on getting the 1.35.0 release out the door and the new website design. I especially like the docs for the old releases being easy to find. However, looking at the announcement and the docs I noticed that PropertyTree is again not in the official release. A quick search on gmane didn't provide me with the reason for this. Whatever the reason, will it be in the next release? What needs to be done to ensure this? There were a couple patches submitted by myself and others in the bugtracker. Any updates on the status of applying these? Thanks, -Ryan PS -- I also noticed a directory "boost/pending" in the distribution. Just curious as to what this is.

[serialization] boost 1.35.0 / gcc 4.3.0 / 64-bit problem
by bernd.speiser＠t-online.de 31 Mar '08

31 Mar '08

Dear all, I apologize for cross-posting (part of this was already reported on boost-users), but maybe this list is better suited for the problem. I also have some additional information from some more experimentation. Here are the facts: (1) We use several machines for development, all under openSuSE 10.2, some of them 32-, some 64-bit systems. Recently, we have installed gcc 4.3.0. We employ several boost libraries, most notably serialization. (2) boost 1.35.0 (RC2) compiles and installs fine on 32-bit with gcc 4.3.0. Serialization code works fine, as far as we use it. (3) On the 64-bit system, however, version 1.35.0 does not compile with gcc 4.3.0: MkDir1 bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_iarchive.o In file included from libs/serialization/src/polymorphic_iarchive.cpp:18: ./boost/archive/polymorphic_iarchive.hpp:88: error: ‘virtual void boost::archive::polymorphic_iarchive_impl::load(int64_t&)’ cannot be overloaded ./boost/archive/polymorphic_iarchive.hpp:84: error: with ‘virtual void boost::archive::polymorphic_iarchive_impl::load(long int&)’ ./boost/archive/polymorphic_iarchive.hpp:89: error: ‘virtual void boost::archive::polymorphic_iarchive_impl::load(uint64_t&)’ cannot be overloaded ./boost/archive/polymorphic_iarchive.hpp:85: error: with ‘virtual void boost::archive::polymorphic_iarchive_impl::load(long unsigned int&)’ "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -fPIC -pthread -DBOOST_ALL_NO_LIB=1 -DBOOST_SERIALIZATION_DYN_LINK=1 -I"." -c -o "bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_iarchive.o" "libs/serialization/src/polymorphic_iarchive.cpp" ...failed gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_iarchive.o... gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_oarchive.o In file included from libs/serialization/src/polymorphic_oarchive.cpp:18: ./boost/archive/polymorphic_oarchive.hpp:86: error: ‘virtual void boost::archive::polymorphic_oarchive_impl::save(int64_t)’ cannot be overloaded ./boost/archive/polymorphic_oarchive.hpp:83: error: with ‘virtual void boost::archive::polymorphic_oarchive_impl::save(long int)’ ./boost/archive/polymorphic_oarchive.hpp:87: error: ‘virtual void boost::archive::polymorphic_oarchive_impl::save(uint64_t)’ cannot be overloaded ./boost/archive/polymorphic_oarchive.hpp:84: error: with ‘virtual void boost::archive::polymorphic_oarchive_impl::save(long unsigned int)’ "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -fPIC -pthread -DBOOST_ALL_NO_LIB=1 -DBOOST_SERIALIZATION_DYN_LINK=1 -I"." -c -o "bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_oarchive.o" "libs/serialization/src/polymorphic_oarchive.cpp" ...failed gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/polymorphic_oarchive.o... gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/stl_port.o gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/text_iarchive.o gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/text_oarchive.o gcc.compile.c++ bin.v2/libs/serialization/build/gcc-4.3.0/debug/threading-multi/void_cast.o (4) Moreover, when compiling (on a 64-bit machine; on 32-bit this is ok) our application code with boost 1.34.1 and gcc 4.3.0, as soon as we #include "boost/serialization/vector.hpp" (even without using any serialization functionality) we receive error messages: /usr/local/include/boost-1_34_1/boost/serialization/vector.hpp:126: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >' /usr/local/include/boost-1_34_1/boost/serialization/vector.hpp:126: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >' /usr/local/include/boost-1_34_1/boost/serialization/vector.hpp:126: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >' /usr/local/include/boost-1_34_1/boost/serialization/vector.hpp:126: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >' On the same machine the code compiles well with boost 1.33.1. Note that 1.34.1 was compiled with an earlier gcc version.

Boost 1.35: No unordered_map? :(
by Robert Dailey 31 Mar '08

31 Mar '08

I'm really sad to see that unordered_map didn't make it into 1.35. What was the reason for this? When will it be released? When is this next release scheduled? Thanks.

New website, and bugs.
by Rene Rivera 31 Mar '08

31 Mar '08

I know people love their email. But I would really appreciate it if people would add trac issues for bugs they find on the new web site. I get thousands of emails a day, and have 7 IRC channels open, so the likelihood that I'll forget to add issues for the emails and IM messages is very high. Thanks :-) -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail

Hello everybody, I'm Cristianno Martins, I'm starting master degree at State University of Campinas (Brazil), and I'm very interested in participate of a Google Summer of Code Project. This is the first time that I'm intending to develop some open source code. There are many projects listed in GSoC home page, and I almost read all of them, choosing two or three to write a propose. So, I really liked two ideas between the boost potential projects: - safe integer -> basically, a creation of a template class to safely access values in the memory; - parallelizing Boost.Math -> using OpenMP to enable the source of Boost.Math to run in multicore systems. I actually believe that I can do anyone of them, and I wanna propose a project to each one. I only needed to know if anything is being done about some of those. I also wanna know if someone have ideas to be done in these projects and aren't listed at the Boost projects list.

[fusion] Small issues in documentation
by Sergei Politov 31 Mar '08

31 Mar '08

Hi, I've found the following small issues in Boost.Fusion documentation. 1) http://www.boost.org/doc/libs/1_35_0/libs/fusion/doc/html/fusion/ organization.html - I'm pretty sure that rect should not be blank. 2) http://www.boost.org/doc/libs/1_35_0/libs/fusion/doc/html/fusion/support/ is_view.html#fusion.support.is_view.example - line "using boost::mpl::_" does not contain trailing ;. 3) http://www.boost.org/doc/libs/1_35_0/libs/fusion/doc/html/fusion/support/ pair.html#fusion.support.pair.expression_semantics - invalid table. Best Regards, Sergei

[1.35] compile with vc8 the co-existence of vc8 & vc9
by Tan, Tom (Shanghai) 31 Mar '08

31 Mar '08

Hello, I have both VC8 and VC 9 installed on my machine. It's quite smooth to build with vc9. However even if I started from VC8 command line prompt and it seems to build with vc9 still, even if I use this command: " bjam -toolset=msvc-8.0 install". Is there any way to force to go with vc8?I need to build both version of lib. Thanks, Tom

Need help with REGEX expression ( boost::regex_search )
by Danny Gilbert 31 Mar '08

31 Mar '08

Hi ! I work with Visual Studio 2003, C++. I am reading data from a UNICODE file in a std::wstring. (It works fine) I want to find with boost::regex_search a pattern like the following: @@FOREACH(item in list) data @@END I want 3 substrings (submatch) like the following: 1- item 2- list 3- data We can have line feed, carriage return, space, etc. between ( and item, between ) and the data, and between data and @@END. So the following must work: @@FOREACH( item in list ) data @@END I DID MANY THINGS (TRY AND ERROR) AND I CAN FIND the first submatch item and the second submatch list. The third submatch never works. It don't see the @@END command (instruction) and get all the remaining stuff of the string. I used Regex Coach software and Rad Regex Designer but with theses softwares, my REGEX expression works. What is the correct REGEX expression with BOOST ???? Thank you ! :-( -- View this message in context: http://www.nabble.com/Need-help-with-REGEX-expression-%28-boost%3A%3Aregex_… Sent from the Boost - Dev mailing list archive at Nabble.com.

Runtime dynamic dispatcher [was: Overload V2]
by Marco Costalba 31 Mar '08

31 Mar '08

While I was reading the very nice Dynamic Dispatcher Library by Dean Michael Berris (dispatcher-0.2.zip in Vault) I realized that it is possible to magically ;-) get a runtime dynamic dispatcher out of the overload library simply using a container to store overloads ! More, the dispatcher you get is multi-signature (heterogeneous function types), instead of homogeneous function type as is the Dean's one. The key enabler is that class overload has value semantic. Of course with the Dean's one you get more, in particularly you get: - Strategized Index Validation - Strategized Routing - Scheduled/Sequenced Invocation But if you are not interested in this additional features you can give overload a try. I have updated the docs and the examples in Vault (overload_26_3_2008.zip) to reflect this new "discovery" ;-) Dean, I' didn't realized this use of overload as a dispatcher until reading your code, are you still interested in a multi-signature dispatcher? Thanks Marco

Egg Review starts today March 31st
by dan marsden 31 Mar '08

31 Mar '08

The review of the Egg library by Shunsuke Sogame starts today.The library is concerned with the implementation and adaptation of function objects. As function objects are everywhere in Boost and C++, I hope to see plenty of discussion and votes during the review. Introduction: It is not so easy to define Function Objects especially if you want to support Boost.ResultOf and Boost.Lambda. Therefore, as Boost provides iterator_facade and iterator adaptors, Egg provides function_facade and function adaptors. Egg provides the following features: * Workaround for the Forwarding Problem http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1385.htm * Helpers to build Function Objects: * egg::function and egg::function_facade provides the way to build Function Objects which supports Boost.ResultOf and Lambda. * Function Objects Adaptors(in other words, higher-order functions): * egg::curryN supports the currying. * egg::pipable emulates extension methods(C#). * egg::fuse/unfuse emulates variadic functions. * egg::nestN represents nested lambda expressions. * etc... The documentation is on line: http://p-stade.sourceforge.net/boost/libs/egg/ The zipped source code is in Vault/FunctionObjects: http://tinyurl.com/34lgda Tested under: Boost Development Trunk and Boost Version1.34.1. --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?

[proto] design of expr<>
by Markus Werle 31 Mar '08

31 Mar '08

Hi! I want to discuss the internal data structure expr<>: I like the way expr<> is built regarding to the first and second template argument: It is well thought and done to have the expression tag as first argument and some fusion-compatible typelist as its second argument containing the operands. OTOH the third template argument contains redundant information: The docs say: "Proto expression nodes are valid Fusion random-access sequences of their children nodes." So the information about the number of arguments is accessible via some size<T>::type metafunction e.g. depending on result_of::distance<result_of::begin<S>::type result_of::end<S>::type>::type? In my unfinished attempts to write a paper about ET library design (now obsolote, thanks to Eric) I have a statement that any expression representation taking more than 2 template arguments is wrong. Eric, since you always have a good reason for your design: Could you please elaborate on this? Also I ask myself whether there was a good reason not to follow mpl and use types to represent numbers. I'd prefer at least some parallism to mpl here: size_t<c>? Markus

ANN: JSON parser based on Boost.Spirit and under Boost Software License
by Boris 30 Mar '08

30 Mar '08

As there has been some talk about JSON lately: The JSON parser TinyJSON has not only been updated to become a template and work with different string types. I also asked the developer Thomas if his parser can be licensed under the Boost Software License. Thankfully Thomas has changed the license. The parser might be even more useful now for those interested in JSON. See http://blog.beef.de/projects/tinyjson/ for the source code and the documentation. Boris

Boost 1.35.0 released
by Beman Dawes 29 Mar '08

29 Mar '08

Boost is pleased to announce the availability of release 1.35.0. This is a major release that includes 12 new libraries, and coincides with an upgrade and reorganization of the www.boost.org web site. The new libraries are: * Asio: Portable networking, including sockets, timers, hostname resolution and socket iostreams, from Chris Kohlhoff. * Bimap: Boost.Bimap is a bidirectional maps library for C++. With Boost.Bimap you can create associative containers in which both types can be used as key, from Matias Capeletto. * Circular Buffer: STL compliant container also known as ring or cyclic buffer, from Jan Gaspar. * Function Types: Boost.FunctionTypes provides functionality to classify, decompose and synthesize function, function pointer, function reference and pointer to member types. From Tobias Schwinger. * Fusion: Library for working with tuples, including various containers, algorithms, etc. From Joel de Guzman, Dan Marsden and Tobias Schwinger. * GIL: Generic Image Library, from Lubomir Bourdev and Hailin Jin. * Interprocess: Shared memory, memory mapped files, process-shared mutexes, condition variables, containers and allocators, from Ion Gaztañaga. * Intrusive: Intrusive containers and algorithms, from Ion Gaztañaga. * Math/Special Functions: A wide selection of mathematical special functions from John Maddock, Paul Bristow, Hubert Holin and Xiaogang Zhang. * Math/Statistical Distributions: A wide selection of univariate statistical distributions and functions that operate on them from John Maddock and Paul Bristow. * MPI: Message Passing Interface library, for use in distributed-memory parallel application programming, from Douglas Gregor and Matthias Troyer. * System: Operating system support, including the diagnostics support that will be part of the C++0x standard library, from Beman Dawes. Among existing libraries, Boost.Threads has been upgraded to reflect changes made by the C++ committee in the process of including Boost.Threads in C++0x. Dozens of people contribute to each Boost release. Rene Rivera, Daniel James, and John Maddock were instrumental in readying this release. It wouldn't have happened without them. --Beman Dawes, Release Manager

[pool] A pool object as allocator to std container?
by Gregory Dai 29 Mar '08

29 Mar '08

I was able to use something like the following: boost::object_pool<std::set<int> > front; but I'd instead want to be able to use: boost::object_pool<int> back; boost::object_pool<std::set<int, boost::object_pool<int> > front(back); which is not possible because the object_pool does not conform to the standard allocator interface. For the time being it's possible to do: boost::object_pool<std::set<int, boost::pool_allocator<int> > front; but an element set from the pool does not interact well with a plain std::set<int>. Any suggestion on a solution? Thanks, Greg

Proto grammars are context-free, so I think that forces you to do the compatibility checking as a separate step with a transform, as you suggest. It would be an interesting exercise to try to imagine what a context-sensitive Proto grammar might look like, but for now we have to make do. Since Dave also wants to do terminal-based compatibility checks, I banged together an example. The following transform checks to see if all terminals have the same type. It uses a state parameter that is callable ... you stuff terminal types into it and it keeps track of whether they're all the same or not. Pretty simple. The only tricky bit is treating the result of the _state transform as callable and invoking it. I use proto::bind for that (to be renamed proto::lazy). #include <iostream> #include <boost/assert.hpp> #include <boost/mpl/or.hpp> #include <boost/mpl/and.hpp> #include <boost/type_traits/is_same.hpp> #include <boost/type_traits/is_void.hpp> #include <boost/xpressive/proto/proto.hpp> #include <boost/xpressive/proto/transform.hpp> namespace mpl = boost::mpl; namespace proto = boost::proto; template<typename IsValid = mpl::true_, typename Value = void> struct Accumulator : IsValid { template<typename Value2> struct validate : mpl::and_< IsValid , mpl::or_< boost::is_void<Value> , boost::is_same<Value, Value2> > > {}; template<typename Sig> struct result; template<typename This, typename Value2> struct result<This(Value2)> { typedef Accumulator<validate<Value2>, Value2> type; }; template<typename Value2> typename result<void(Value2)>::type operator ()(Value2 const &) const { return typename result<void(Value2)>::type(); } }; struct SameTerminals : proto::or_< proto::when< proto::terminal<proto::_> // treat the current state as a callable // object and pass it the value of the terminal. , proto::bind<proto::_state(proto::_arg)> > , proto::otherwise< proto::fold<proto::_, proto::_state, SameTerminals> > > {}; int main() { int dummy = 0; proto::terminal<int>::type i = {0}, j = {1}, k = {2}; proto::terminal<short>::type s = {42}; BOOST_ASSERT( SameTerminals()(i+j*k, Accumulator<>(), dummy) ); BOOST_ASSERT(!SameTerminals()(i+s*k, Accumulator<>(), dummy) ); } Note that this example exposed a bug in the proto::make transform, which is already fixed. Be sure to get the latest, either from the file vault or subversion. > Second, I have a grammar where I can add terminals 'a+b' and index terminal > 'a[b]'. you can have '(a+b)[c]'. some terminals may be indexable but other > not.
