boost::program options question. Implicit() doesn't seem to work

Hi, I was playing around with the boost::program_options class... According to the documentation the line: desc.add_options() ("debug", po::value<std::string>()->implicit(), "enable debugging" ); enables me to do something like this: myexec --debug However, if I do that I get an assertion error. The code requires a string so this will work: myexec --debug whatever What am I doing wrong? Is it me or is it the library? I'm using Visual C++ 2005 Express Beta, WinXP Pro Service Pack2. Thanks, Alexis Below my test program: namespace po = boost::program_options; int main (int argc, char **argv) { po::options_description desc("Allowed ptions"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ("debug", po::value<std::string>()->implicit() ,"enable debugging" ) ; po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc),vm); po::notify(vm); if (argc==1 || vm.count("help")) { std::cout << desc << "\n"; return 1; } if (vm.count("compression")) std::cout << vm["compression"].as<int>() << std::endl; if (vm.count("debug")) std::cout << vm["debug"].as<std::string>() << std::endl; if (vm.count("log-file")) std::cout << vm["compression"].as<std::string>() << std::endl; } (By the way, the section Syntactic information of the documentation is not accurate when it says I could do this: desc.add_options() ("compression", "compression level",value<string>()) ("verbose", "verbosity level",value<string>()->implicit()) ("email", "email to send to",value<string>()->multitoken()); That doesn't compile. If I put the second string as the last argument it works.) Programming Tutorial: In Python: To do this, do this In Perl: To do this, do this or this or this or this... In C: To do this, do this, but be careful In C++: To do this, do this, but don't do this, be careful of this, watch out for this, and whatever you do, don't do this __________________________________ Celebrate Yahoo!'s 10th Birthday!

how to get regex to link in windows?
by Alexis H. Rivera-Rios 16 Mar '05

Another frustrating day trying to compile some code... I'm trying use the regex library. My application is compiled using Multi-threaded Debug DLL (/MDd). I specified the following library libboost_regex-vc71-mt.lib and all I get are link errors. My application is a console app so I defined BOOST_REGEX_NO_W32 I've tried setting BOOST_REGEX_DYN_LINK and BOOST_REGEX_NO_LIB but that doesn't cut it. The funny thing is that Im also using the filesystem library, and I link with the same type of library libboost_filesystem-vc71-mt.lib and I don't get any problems with the compiler. I'd appreciate if someone can point out what I'm doing wrong. Thanks, Alexis Try #1: Defining BOOST_REGEX_DYN_LINK BOOST_REGEX_NO_LIB BOOST_LIB_DIAGNOSTIC BOOST_REGEX_NO_W32 Specifying as the link libraries libboost_filesystem-vc71-mt.lib

Thread ...memory leaks on windwos msvc71
by zhengyi 16 Mar '05

16 Mar '05

Now,I found some memory leaks of boost::thread library. I trace down the code and find that when thread lib's dll is loading , a mutex was created in the boost_thread-vc71-mt-gdp-1_32.dll::dllmain() function's "case DLL_PROCESS_ATTACH:" branch .In on_process_enter(), I found that boost::mutex* threadmon_mutex was created. When the program is exiting , in "case DLL_PROCESS_DETACH:" branch of Dllmain() , the code does not kill the threadmon_mutex , so , some memory was leaked. In MFC project , the memory leak can be detected by the vs71. but in win32 console project , vs71 does not report the problem ,althrogh the memory leak exits ( at least I think there is memory leak , because i found that the mutex constructor was call one more time than it's destructor). Any one Can tell me the solution? Is it a bug of thread or a bug of my brain or a bug of msvc71 ? 　　　　　　　　　　　　　　gooodmen(a)x263.net 　　　　　　　　　　　　　　　　　2005-03-16

I'd like to run a test here to be sure; could you please supply an example of <internationalized chars> that is causing the problem? I'm not at all surprised you are having problems; it isn't at all clear to me that it is possible to do reliable processing on Windows using the A (narrow) variants if Unicode characters are present. I've got the internationalized revision of the Filesystem library running on Windows; it seems to be handling wide characters with ease. I'm testing now on POSIX - I couldn't resist the $499 price tag and bought a Mac Mini. Slick. One fix for your problem is to switch to the internationalized version and use wchar_t based paths. That will use the W Windows variants, and will also work well on POSIX systems with internationalized file or directory names. Another possibility is that we can work on the narrow functions to make them function better in the face of internationalized names. But I'd need a lot of help on that to develop test cases and strategies to handle them. Thanks for the report, --Beman

is_integral_c

MPL currently contains type trait metafunctions for is_sequence and is_placeholder. Shouldn't it also contain is_integral_c for checking integral constant wrappers? Eric.

Bind regression from 1.30 to 1.32
by Thomas Matelich 15 Mar '05

15 Mar '05

This may be a reasonable regression, but I thought I'd bring it up in case its a regression that should be fixed. My sample code and some error outputs are attached. Oh, and in case you're wondering why I would do this, its basically because I really like the find_if/bind/equal_to thing, and I need the char[64] for easy fwrite/fread'ing. Thanks

wregex undefined workaround
by pps 15 Mar '05

15 Mar '05

Hello, I use freebsd 4.11 & gcc3.3.6 and gcc 3.4.4 with both I don't have std::wstring defined. I only need it fo some internal use. So, I defined: typedef unsigned short uchar16 typedef basic_string<uchar16> string16; and it was enough for me (I don't do iostreams with this string) But, I need regex support for this. As I read in a few mail boost does not create wregex on some platforms with limited support for wchar_t, so I tried to create one the same as I did with string: typedef reg_expression<uchar16, regex_traits<uchar16>, BOOST_DEFAULT_ALLOCATOR(uchar16)> regex16; When I try to use regex16 I get a big load of errors. Did I missed something? Thanks

Mutex synchronized LockingPtr in Boost?
by Christopher D. Russell 15 Mar '05

15 Mar '05

Is there a class in Boost that implements functionality similar to Andrei Alexandrescu's mutex-synchronized LockingPtr as described in his Feb. 2001 CUJ article http://www.cuj.com/documents/s=7998/cujcexp1902alexandr/? I checkout boost::smart_ptr but don't see that any of these deal with interprocess / interthread synchronization. - Regards Chris -- --- Chris Russell, Encapsule Systems, Inc., Yarmouth, Maine USA 04096 http://encapsule.com // http://hyperworx.org // http://chrisrussell.net cdr(a)encapsule.com // voice (207) 846-7773 // mobile (207) 671-5963 Skype user "encapsule"

[boost graph] adjusting vertex_descriptors when performing a remove_vertex
by Yariv Tal 15 Mar '05

15 Mar '05

In our project we need the ability to associate an object with a vertex, so naturally I add the object ptr as a vertex property. However, we also need to access the vertex according to the object (for example, for performing a shortest-path algorithm from the vertex representing the specific object). So, I also have a map mapping a vertex_descriptor for each object: typedef std::map<ObjectPtr, GraphTraits::vertex_descriptor> ObjVertexMap; Now, the problem is that when an object/vertex is removed from the graph, depending on the container holding vertices (vecS vs. listS), a renumbering of the vertex_descriptors may occur (or may not...) For example: (The typedefs are pretty large and not neccessarily needed to understand the code - so may want to skip them) // *** TYPEDEFS START HERE typedef std::map<ObjectPtr, GraphTraits::vertex_descriptor> ObjVertexMap; typedef Object * ObjectPtr; // Define new prperty struct vertex_obj_t { typedef boost::vertex_property_tag kind; }; // Define graph type typedef boost::adjacency_list< boost::vecS, boost::vecS, // If this is boost::listS then no renumbering on vertex delete??? boost::directedS, boost::property<vertex_tmfobj_t, ObjectPtr>, > GraphType; // *** TYPEDEFS END HERE class GraphMgr { protected: GraphType m_graph; ObjVertexMap m_objects; public: bool addEntity(ObjectPtr a_obj) { if (m_objects.find(a_obj) != m_objects.end()) { return false; } GraphTraits::vertex_descriptor newVertex = boost::add_vertex(Graph::vertex_property_type(a_obj), m_graph); m_objects.insert(ObjVertexMap::value_type(a_obj, newVertex)); return true; } bool removeEntity(const ObjectPtr a_obj) { ObjVertexMap::iterator itr = m_objects.find(a_obj); if (itr == m_objects.end()) { return false; } boost::clear_vertex((*itr).second, m_graph); boost::remove_vertex((*itr).second, m_graph); // will this do a renumbering of the vertices? m_objects.erase(itr); // !!! If renumbering of the vertices was made I must update the ObjVertexMap! return true; } }; The problem is that if I use one type of container for vertices, the vecS, then renumbering on remove_vertex occurs and I need to update all indices in m_objects - this means I need to KNOW that vertex_descriptor is an index and how remove_vertex is implemented... Even worse: as far as I undertand if I use listS then vertex_desfcriptor is no longer an index an no renumbering occurs in remove_vertex! So, unless I want to commit to using vecS and to a specific implementation I need to somehow KNOW whether or not to perform renumbering. I coulld do this via a traits template with sepcialization for each vertices container type, but it seems to me that the library should have (and probably has) a better way of abstracting this, no? Perhaps the problem is that I'm storing vertex_descriptors in the ObjVertexMap, which may be defined as transient entities that (like iterators after an erase) might be invalidated after a remove_vertex - but then, how can I hold some persistent and efficient identifier into the graph that remains valid after remove_vertex? If anyone has any ideas, plz help. Yariv.
