Strings tagged with their character set
by Phil Endecott 10 Jan '08

10 Jan '08

Dear All, Something that I have been thinking about for a while is storing strings tagged with their character set. Since I now have a practical need for this I plan to try to implement something. Your feedback would be appreciated. The starting point is the idea that the character set of a string may be known at compile time or at run time, and so two types of tagging are possible. First compile-time tagging: template <character_set> class tagged_string { ... }; tagged_string<utf8> s1; tagged_string<latin1> s2; Some typedefs would be appropriate: typedef tagged_string<utf8> utf8string; Now run-time tagging: class rt_tagged_string { private: character_set cs; public: rt_tagged_string(character_set cs_): cs(cs_) ... ... }; rt_tagged_string(utf8) s3; (Consise-yet-clear names for any of these classes would be great.) I propose to implement conversion between the strings using icode and/or GNU recode. It would be easy to allow this conversion to happen invisibly, but it might be wiser to make conversion explicit. I'm not sure what the 'character_set' that I've used above should be. It needs to be some sort of user-extensible enum or type-tag. We need character types of 8, 16 and 32 bits. wchar is not useful here because it's not defined whether it's 16 or 32 bits. So I propose the following, modelled after cstdint: typedef char char8_t; typedef <implementation-defined> char16_t; typedef <implementation-defined> char32_t; I then propose a character_set_traits class: template <character_set> class character_set_traits; template <> class character_set_traits<utf8> { typdef char8_t char_t; const bool variable_width = true; ... }; For the fixed-width, compile-time-tagged strings I think it makes sense to inherit from std::basic_string< character_set_traits<charset>::char_t >. The only problem I can see with this is that latin1string s1 = "hello world"; s1.substr(1,5) <--- this returns a std::string, not a latin1string If latin1string has a constructor from std::string (which is its own base type) that's fine, i.e. we can still write: latin1string s2 = s1.substr(1,5); but unfortunately we can also write latin2string s3 = s1.substr(1,5); which is not so good. So a different approach is to define a set of character-set-specific character types, and build string types from them: typedef char8_t latin1char; typedef char8_t latin2char; For variable-width character sets, the methods of std::string are less useful (though far from useless). I understand that there's already a utf8 iterator somewhere in Boost, can it help? For run-time character sets, is there any way to provide e.g. run-time iterators? I imagine these strings being used as follows: - Input to the program is either run-time or compile-time tagged with any character set. - Data that is not manipulated in any way it just passed through. - Data that will be processed will first be converted to a suitable, compile-time-tagged, character set, and if appropriate converted back afterwards. So the absence of (useful) string operations on run-time-tagged or variable-width character set data is not a problem. For conversions, there is the question of partial characters in variable-width character sets. If a program is processing data in chunks it may be legitimate for a chunk boundary to fall in the middle of a UTF8 character. IIRC, icode has a method to deal with this which we could expose in a stateful converter: charset_converter utf8_to_ucs4(utf8,ucs4); while (!eof) { utf8string s = get_chunk(); ucs4string t = utf8_to_ucs4(s); send_chunk(t); } utf8_to_ucs4.flush(); - but many applications may only need a stateless converter. I will be working on this over the next couple of weeks, so any feedback would be much appreciated. Regards, Phil.

Re: [boost] Switch: return type deduction

[auto_link][thread] Including boost/thread/thread.hpp requires linking against date_time?
by Andreas Huber 09 Jan '08

09 Jan '08

Hi In a Visual Studio 2008 project, when I include the trunk version of boost/thread/thread.hpp, it seems I must also link against the date_time library. When I build the same program with bjam, while not linking against date_time, the resulting program runs just fine. So my question is: Why does including thread.hpp require linking against the date_time library? It seems that it is not needed at all? Thanks & Regards, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.

Switch library review extended to Sunday, Jan 13th
by Stjepan Rajko 09 Jan '08

09 Jan '08

The review for the Switch library has been extended to Sunday, January 13th. I hope that the extended period will provide an opportunity for more reviewers to submit their vote, and give enough time for the discussion on design to resolve. As this library is both small and seen as very useful, it seems preferable to take advantage of the momentum of the ongoing discussion between very knowledgeable reviewers and a very knowledgeable author, and get this ironed out now.

[log] Boost Logging v2 - new version (v0.13.6)
by John Torjo 09 Jan '08

09 Jan '08

Boost Logging v2 - new version (v0.13.6) The Boost Logging Lib v2 is getting closer and closer to its review (Feb 4). I've just released a new version, lots of new features: * added tags (attributes a logged message can have, like : line & file, function name, time, etc.) * scoped logs * caching messages before logs are initialized * high precision time (as tag as well) * added spacer formatter - you can specify what goes before and after your formatter * new formatter: named_spacer : Allows you to contain multiple formatters. You have a spacer string, and within it, you can escape your contained formatters * new destination : named - like named_spacer, but for destinations All in all, I've added quite a few features - so, take a look! Look forward to your feedback! http://www.torjo.com/log2/ http://torjo.blogspot.com/2008/01/boost-logging-v2-new-version-v0136.html Best, John -- http://John.Torjo.com -- C++ expert ... call me only if you want things done right

formal review of Switch library ends tomorrow (Wednesday, January 9th) - reviews needed
by Stjepan Rajko 08 Jan '08

08 Jan '08

The formal review of Switch library by Steven Watanabe is scheduled to end tomorrow, January 9th. I have only received one review (privately) so far, and hope that those participating in the discussions about the library (as well as any other interested boosters) would be willing to contribute a few more - a summary of your final thoughts with a vote would be greatly appreciated. If you need a little extra time to finish out the discussions or write the review, please let me know as we can extend the review period for a few days if necessary. Please feel free to submit your reviews to the list, or privately to me. As a reminder, here are some questions you may want to answer in your review: * 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? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Thanks again to those that have been participating in the discussions and/or have already submitted a review. Regards, Stjepan
