Boost 1_58_0_rc1 is available for testing
by Marshall Clow 25 Mar '15

25 Mar '15

Release candidate files for 1.58.0 beta 1 are available at http://boost.cowic.de/rc/ As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. This helps ensure the candidates build OK before we push them out to SourceForge. IMPORTANT NOTE: There is a bug with the build scripts; you have to specify the address-mode and architecture to b2. I used: ./b2 address-model=64 architecture=x86 to test this. The files (and associated md5s) are: MD5 (boost_1_58_0_b1_rc1.7z) = 302c7dfc917227843d24beed33ccc99c MD5 (boost_1_58_0_b1_rc1.tar.bz2) = d7d030e85bf5534a328c108c62a7fb0e MD5 (boost_1_58_0_b1_rc1.tar.gz) = ec90cd23bdc99c5eaf88245ea94a28e0 MD5 (boost_1_58_0_b1_rc1.zip) = dc8379fb95c84fe2fca53a4b2c96da23 Thanks! -- The release managers

This is the location of the new documentation: http://www.boost.org/doc/libs/develop/libs/test/doc/html/index.html I do not know about the update frequency In order to build the doc: cd $boost/libs/test/doc ../../../bjam -sDOCBOOK_XSL_DIR=/some/path/docbook-xsl-1.78.1/ -sDOCBOOK_DTD_DIR=/some/path/docbook-xml-4.2/ Doxygen should be in the $PATH. The previous command will build whatever is necessary. Best, Raffi

[Hana] Informal review request
by Louis Dionne 24 Mar '15

24 Mar '15

Dear Boost, As some may be aware of, I am currently working on a metaprogramming library called Hana, with the intention of proposing it for inclusion in Boost. The purpose of that library is to act as a toolbox for expressing computations on both types (like the MPL) and heterogeneous values (like Fusion). The library is built around C++14 idioms and implementation techniques to maximize expressiveness and performance. I am now requesting feedback from the community, with the intention of asking for a formal review in the next months. A similar review was asked for in last August. The library has undergone several modifications since then, both to address issues raised during the review and for general improvement. Here are some issues that were raised during the review and addressed: - Usage of names and terms unknown to C++ programmers: Efforts were made to make this better, and several functions were renamed (`fmap` is now `transform`). When possible, the documentation also uses terms more familiar to C++ programmers, like concept instead of "type class". - The order of the arguments to some algorithms was unfortunate for C++. It was consistent with Haskell, but it turned out to be cumbersome in C++. This is changed in most places. - Inability to easily implement individual algorithms: This is fixed, and algorithms are now standalone structures using tag-dispatching, almost exactly as in Fusion. - Lack of a good introductory tutorial: A lot of work has gone into improving both the tutorial and the reference documentation. - Lack of support for mainstream compilers: The library is now almost fully functional with Clang 3.5. A GCC 4.9 port with reduced functionality is also underway on the `redux` branch. The library is available at [1] and the documentation at [2]. Comments should be directed to this mailing list, while bugs and other similar problems should be directed to the GitHub issue tracker. Please participate, especially if you have interest and/or experience in metaprogramming; after all, you represent the target audience for Hana. Thank you, Louis Dionne [1]: https://github.com/ldionne/hana [2]: http://ldionne.github.io/hana/

boost regex recursive quesion
by 温西波 24 Mar '15

24 Mar '15

This is my first time to using maillist I'm learning to use boost::regex for a month , a few days ago I found a problem( maybe is my mistake ?) I construct a simple recursive regular expression: a(?0)? This regex contains a recursive call (?0). It should match a string with any arbitrary length filled with 'a' characters. regex_match only returns true for "a" and "aa", but failed to match "aaa" and any string longer than three characters. Why? I try it on boost 1.45 and 1.57 , both get same result . I had sent this question on stackoverflow , but had not get a answer now . Is there any flag should be used with regex_match to use recursive call ? Thank you .

[rational] has no maintainers
by Peter Dimov 23 Mar '15

Currently, nobody has write access to Boost.Rational, and I see a number of open pull requests (mostly by John Maddock) lingering. John, would you like write access to it so that you can apply your suggested changes?

BOOST_SYMBOL_VISIBLE
by Robert Ramey 23 Mar '15

23 Mar '15

I'm trying to get my MAC OS (Yosemite) to build the boost serialization library and I've having a problem. In a couple of tests, the program throws some exceptions. When this occurs I get a message something like "terminate called after throwing an instance of 'boost::archive::archive_exception'". I'm quite sure that I used to be able to do this without problem - as of a couple of months ago. I recently "upgraded" to Yosemite. My gcc-4.8.1 version I'm getting from HPC website. In the course of trying to figure this out, I've come upon boost documentation which explains BOOST_SYMBOL_VISIBLE which was new to me. It suggests that my code which looks like class archive_exception : public virtual std::exception { ... could be creating a problem. due to deriving from some other class which might be defined a runtime shared library. So I replaced it with: class BOOST_SYMBOL_VISIBLE archive_exception : public virtual std::exception { ... and I also tried class BOOST_SYMBOL_VISIBLE archive_exception : public virtual std::exception { ... This doesn't change anything so it looks like I'm barking up the wrong tree. Is there anyone here who might want to shed some light on this?

Multiple-pattern string search algorithms
by meghana madhyastha 23 Mar '15

23 Mar '15

Hi all ! I noticed that Boost's algorithm module does not include multiple pattern string searching algorithms such as the Rabin Karp algorithm and Aho-Corasick algorithm. I think these algorithms are very useful and should be implemented in the library. If no one is currently working on them, I am willing to implement them. Please let me know your opinion. Regards, Meghana
