compile time (template or preprocessor) text processing
by Laszlo Marak 06 Dec '10

06 Dec '10

Hello, My question is c++ related (I like to call the topic extreme c++ programming). We all know the excellent boost python framework, which exports c++ functions to python with spectacular elegance. As for the documentation of those functions boost offers a string parameter, which can contain the description of the particular function. Sometimes this documentation is already written (for example in doxygen). It would be good to import this documentation somehow to python. Is there a possibility to generate a std::string from a FILE following some rules using template meta-programming (or possibly the preprocessor)? For example my_function.cpp ///************* // this is the documentation of my_function // void my_function() { cout << "I've been called.\n" } boost_export.cpp def( "my_function", &my_function, (args()), generate_the_doc_in_compile_time_from<>("my_function.cpp") ) Here the generate_the_doc_in_compile_time_from<>("my_function.cpp") would hard-wire the docs into def at compile time, so it would no longer depend on my_function.cpp. Any ideas would be greatly appreciated.

Lookup on composite key in MultiIndex
by Chris Jewell 06 Dec '10

06 Dec '10

Hi All, A question about fast lookup on ordered indices, if I may. I have a data structure: struct Individual { double I; double N; ... } I need some way of indexing Individuals such that I can perform queries such as "Return the set of Individuals such that Individual::I < T and Individual::N > N". I'm currently using a MultiIndex that orders the individuals by Individual::I, and therefore gives me fast lookups on the I field. I had thought about creating a composite key on both I and N, and then using the range() method to return iterators to the required individuals. However, I can't seem to find the correct syntax for a predicate for the composite key. Can anyone help me out? Is there a better way to achieve what I need? Thanks, Chris -- Dr Chris Jewell Department of Statistics University of Warwick Coventry CV4 7AL UK Tel: +44 (0)24 7615 0778

[Quickbook 1.4] template for link to issue ?
by Martin Moene 06 Dec '10

06 Dec '10

Hi, Still using Quickbook 1.4, I've not been able to create a template for linking to items in our issue database. Writing out the following works: \[[@https://host.domain/issues/view.php?id=121 #121]\] Text.. Giving: [#121] Text... I tried (several variations of) a macro like: [template issue[key] [@https://host.domain/issues/view.php?id=[key] #[key]] ] Using: * \[[issue 121]\] Text... However none had the desired effect. (I prefer to include the \[, \] inside the template.) Should I write the template differently, or do I have to upgrade to a newer version of Quickbook? Can someone give a hint? Thanks in advance.

mpi: sending/receiving different types
by Hicham Mouline 06 Dec '10

06 Dec '10

Hi, I will be sending messages of different kinds. The destination will not know what kind of message it is trying to receive. Imagine I send many messages of the same kind. I understand the tag in send/receive will be different in each case? Or can I send 2 messages of the same king with the same tag? That way the receiver can use the tag to identify what it is it is receiving. If so, is the receiver supposed to use the recv() function with different template argument T until the call succeeds ? Or should I always use packed_<oi>archive? rds,

Re: [Boost-users] [gil] Using gil::color_converted_view with gil::for_each_pixel
by Chris Yuen 05 Dec '10

05 Dec '10

Hello Christian, Thanks for your guidance! I took a look at semantic_at_c() and get_color() and they seem to do the trick! Here's a couple of more questions. I've posted a compiling, annotated code at http://boost.codepad.org/Fy2vP73l Below is the more elaborate description of my questions which can be found in the code: 1. Can I specify which channel to get in nth_channel_view()? For example, if I want to set the red channel to 255 for all the pixels, I would do gil::fil_pixels(gil::nth_channel_view(view, 0), 255). However, that only works if our view is rgb8 or bgr8, not argb8. Is there a way I can say something like gil::fill_pixels(gil::nth_channel_view(view, gil::find_channel_for_view(view, gil::red_t())), 255) ??? 2. This compiles gil::gil_function_requires<gil::ImageViewConcept<int> >(); Strange. Any ideas? Best regards, Chris Yuen P.S. I am definitely interested in reviewing the extension! Apparently I'm a begginer in GIL. How would you like me to review and where should I write to?

Help with Visual Studio settings for Boost Serialization
by Abdullah ARSLAN 05 Dec '10

05 Dec '10

I am trying to implement very simple sample of boost serialization. I have a sample class, class1. It only contains a simple int variable. I followed the examples given here : http://www.boost.org/doc/libs/1_45_0/libs/serialization/doc/index.html <http://www.boost.org/doc/libs/1_45_0/libs/serialization/doc/index.html> I also think that i followed this guideline : http://beta.boost.org/doc/libs/1_44_0/more/getting_started/windows.html but i am not sure... Here is the error i get: error LNK2019: unresolved external symbol "private: void __thiscall class1::serialize<class boost::archive::text..... Could you help me with this error or could you guide me with installation and running a very simple serialization example, step by step... like download this, install this and etc... I am using visual studio 2008 express... Thanks in advance..

[message_queue.hpp]is it possible to retrieve a file descriptor for a boost message queue
by rohini chandra pallapothu 05 Dec '10

05 Dec '10

Hi, Could you anyone please let me know if it is possible to wait on a boost message queue (even if it is in the future versions of boost). I could not find any function from the boost documentation that can be used to retrieve a file descriptor of boost message queue.I wanted to get it confirmed. Best Regards, Rohini Chandra

Hi! It is possibile to transform a string representing a hexadecimal number in the format "0xnumber" or "number" (without "0x") in an integer with lexical_cast<>? -- View this message in context: http://boost.2283326.n4.nabble.com/Lexical-cast-and-hex-number-tp3070247p30… Sent from the Boost - Users mailing list archive at Nabble.com.
