bounded_iterator
by Chad Parry 10 Jan '08

10 Jan '08

I created a "bounded_iterator" concept that seems really useful. A bounded_iterator behaves just like a regular iterator, except that the termination condition can be checked by just casting the iterator to a bool. Here's an example: int array_range[] = { 1, 1, 2, 3, 5 }; for (bounded_iterator<int *> i(array_range); i; ++i) { std::fill_n(std::ostream_iterator<int>(std::cout), *i, *i); } I like it for the same reason that I like iterator_range: it frees the developer from having to worry about both a begin and an end iterator. It can be used as a wrapper for operations on a container or a sub-range. Just like iterator_range simplifies the invocation of functions for ranges, bounded_iterator simplifies the traversal of ranges. In my application I was storing lots of iterators in containers, and using bounded_iterator proved to be a better abstraction than storing iterator pairs or ranges. The main disadvantage to using a bounded_iterator is that it competes with the standard iterator concept, and it's usually more confusing to support many ways to do the same thing. Here is a simple implementation: template<typename base_iterator> class bounded_iterator : public boost::iterator_adaptor<bounded_iterator<base_iterator>, base_iterator> { base_iterator const end; typedef boost::iterator_adaptor<bounded_iterator, base_iterator> super_type; struct unspecified_bool_helper { int true_tag; }; typedef int unspecified_bool_helper::*unspecified_bool_type; public: template<typename source_iterator> bounded_iterator(source_iterator begin, source_iterator end) : super_type(begin), end(end) { } template<typename source_range> bounded_iterator(source_range &range) : super_type(boost::begin(range)), end(boost::end(range)) { } template<typename source_range> bounded_iterator(source_range const &range) : super_type(boost::begin(range)), end(boost::end(range)) { } operator unspecified_bool_type() const { return super_type::base() == end ? 0 : &unspecified_bool_helper::true_tag; } }; -- chad

The rationale was to allow non-returning default function objects that work regardless of the type (such as 'throw_'). It's probably not that important... > I don't think the comma operator > is a completely fool-proof way to detect void.

No, because the operator is binary and one operand can have a reserved type which is only internally used by the test code. Regards, Tobias

Hi, yesterday bug #1550 which was opened by me (and has me in CC: too!) was closed but I still miss an associated mail. Can you please check the mail log whether the mail was rejected? It happened in the past that mails could not be delivered to me if a postmaster account is missing on the server. Can you check this? What is the problem? (Yep, I checked my SPAM folder.) Jens

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.

[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.
