Popularity of boost versus popularity of pcre

Recently, there were two recursive PKGREVISION bumps in pkgsrc. One was after an update of devel/boost and the other was after an update of devel/pcre (Perl Compatible Regular Expressions). 59 files were bumped after boost update and 1657 + 68 files were bumped after pcre update. Even though boost has its own regex library but  it's way less popular in open-source world than pcre. You can draw your conclusions.

Boost bugs

I spent few hours today and yesterday closing my bugs. #2768 [any] Unique type_info #2749 [any] multi method for boost::any and modified boost::any to fit multi method #2748 [any] implement reset for direct constructing (adapt to noncopyable) #2295 Inconsistent behavior when using 64 bit integer types #754 boost::any - typeid comparison across shared boundaries #922 Lexical cast and wide characters #2045 lexical_cast of short unsigned produces warnigns with g++ and -Wsign-promo #2558 Unnecessary conversion warning in lexical_cast #3198 compiler warnings in VC9 #1847 Can't compile without header, boost::lexical_cast problem #1791 fix warning on MSVC warning level 4 They are all now closed.

ScopeExit Review Announcement

http://thread.gmane.org/gmane.comp.lib.boost.devel/163149 Alexander Nasonov's ScopeExit submission will be formally reviewed August 13 - August 22. The current submission has been uploaded to http://boost-consulting.com/vault/index.php?action=downloadfile&filename=scope_exit-0.04.tar.gz&directory=& It's also available at http://tinyurl.com/2z6qg2 Online documentation is here http://194.6.223.221/~nasonov/scope_exit-0.04/libs/scope_exit/doc/html/index.html

[boost] Announce: scope_exit version 0.03

Version 0.03 is available for download at http://tinyurl.com/yps8zs

You can read documentation online: http://194.6.223.221/~nasonov/scope_exit-0.03/libs/scope_exit/doc/html/

What's new in this version:

- Based on simpler 0.01 interface but with a better implementation - Found a problem on MSVC. It doesn't link when a block in a header file is included by more than one cpp file. I tried __declspec(selectany) and __forceinline. - Added experimental BOOST_SCOPE_EXIT_FASTER_IMPL. See documentation for details.

I'd like to remind you that nobody volunteered to be a review manager yet.

[boost] [lexical_cast] optimization commited to HEAD

I just posted it to boost-devel list: http://lists.boost.org/Archives/boost/2006/08/109590.php Hello, I recently commited the version 1.26 of lexical_cast.hpp that optimizes many combinations of types. How it works: The lexical_cast reserves a local buffer for bool, char, wchar_t and other integral types. Then it puts a string representation of a source to the buffer. Currently, all such algorithms don't use ostream at all but it's easy to implement a generic algorithm that sets a put area of a ostream object to point to that buffer and puts a string representation to the buffer. When a source type is a pointer to char/wchar_t array or basic_string<>, its value is already a string representation of itself and a call to ostream output operator is omitted. Futher optimization is applied when a target type is either char/wchar_t or basic_string<>. In this case, std streams are not involved in a conversion at all. For all other target types, basic_istream object is contructed, its get area is set to a string representation of a source type and the operator>> is called. Optimization for the following source types is ON: bool char wchar_t other integral types char*, char const*, char[], char const[] wchar_t*, wchar_t const*, wchar_t[], wchar_t const[] std::basic_string<> Optimization for the following source types is OFF: enums float double signed char unsigned char signed char*, signed char const*, signed char[], signed char const[] unsigned char*, unsigned char const*, unsigned char[], unsigned char const[] all other types not listed in ON list Tested on VC6, VC7.1, VC8, gcc 3.4 and Borland 5.5. I couldn't run the test on Borland so I tested only that it compiles.
