[GSoC 2014] [ B-tree + Trie ]
by Cosmin Boaca 19 Feb '14

19 Feb '14

Hello, I am a second year BS student at Politehnica University of Bucharest and I am interested in contributing to boost during GSoC 2014. I would like to work at implementing the B-Tree data structure and continuing the work at the Trie data structure implemented in last year's gsoc. I would like to hear your opinion about this project and I would be glad to discuss with someone that is willing to be a mentor for it. Thank you, Cosmin Boaca

[type_traits] Should namespace boost::align be namespace boost::detail::align?
by Glen Fernandes 18 Feb '14

18 Feb '14

I was working on a tiny library, Boost.Align, which would provide (among other things) a boost::align (that would be std::align if BOOST_NO_CXX11_STD_ALIGN is not defined, or a reasonably non-portable implementation otherwise) and found that type_with_alignment.hpp uses the identifier 'align' for a namespace within namespace 'boost'. Was this namespace intended to not be within boost::detail? If it can be, I'll send a pull request; if not, I'll choose a different identifier over 'align'. Glen

Release script module
by Daniel James 18 Feb '14

18 Feb '14

Now that we have a separate module the release scripts we should remove them from the super project. I'll do that if there are no objections. Do we want to keep it as a submodule, or just completely separate? A lot of the scripts seem to be subversion specific, so can they just be deleted?

[trac] Resolving tickets
by Ahmed Charles 18 Feb '14

18 Feb '14

https://svn.boost.org/trac/boost/ticket/9415 I've never used trac before and I'm trying to resolve this ticket, but I don't think I can. Do I need a 'trac id' to be able to resolve tickets? Or am I simply missing something?

Re: [boost] Just another GSoC project idea: Create a Bjam clone based on the Boost libraries

But all of the generated files have a "zz." prefix. I could either put the big warning also in the source files or remove it from the header files. It seems to me that the naming convention might be enough of a warning. Also, I've liked the prefix since it groups the generated code together. -- Brian Ebenezer Enterprises - In G-d we trust. http://webEbenezer.net

[Boost] [Config] Macros for the absence of a full C++11 <memory> implementation
by Glen Fernandes 17 Feb '14

17 Feb '14

Macros to determine the availability of C++11 functions in <memory> like std::align would be useful to me. (I know that declaration begs the inquiry "What conforming code would you write if std::align is not present?" but that is separate e-mail...) Would a BOOST_NO_CXX11_HDR_MEMORY be generally useful?

[graph] named_graph
by Jan Hudec 17 Feb '14

17 Feb '14

Hello, Looking for a way to add index of vertices by some id to adjacency_list graph I notices it derives from maybe_named_graph that should support this. However I didn't find any example nor really usable description of how to use it (I'd need to define boost::graph::internal_vertex_name, but I don't know what the typedef is supposed to be). Is there any code that uses this, anywhere? -- - Jan Hudec <bulb(a)ucw.cz>
