[spirit2] Documentation?
by Carlos Rafael Giani 31 Dec '08

31 Dec '08

Hello, I have been trying to find the Spirit2 documentation, but all I can find is the Spirit 1.8.5 one. The documentation in boost, too, is the 1.8.5 one. I cannot find it in the spirit svn. Is it in the boost svn? If not, where is it?

Will you be accepting uncommitted reviews? I have an interest in the futures library, but can't promise that I'll have a chance to fully evaluate it. --- Jason Wagner jason(a)nialscorva.net

It's still in the sandbox: https://svn.boost.org/svn/boost/sandbox/thread_safe_signals/trunk The plan is to make a RFC here once I've made the documentation, etc. improvements requested during the review, in order to give the reviewers a chance to look over the changes before it's moved onto the trunk.

[newbie] using non "header-only" boost libraries, but not linking the ".lib"
by Enrique Nieloud 31 Dec '08

31 Dec '08

I'm using filesystem library. I'm using it under vs2005 on windows, and g++ on mac. Instead of linking the .lib I'd like to include the source files of the fs library in my project. I tried to include all the ".cpp" under the filesystem/src directory in the vs2005 project. But the linker still ask for the lib. As far as know I didn't mention the .lib in the project. Why is that? The project files are created using cmake.

[MultiIndex] STL algorithm support for multi_index_containers
by Arno Schödl 31 Dec '08

31 Dec '08

Hello, we have added support for using multi_index ordered index iterators in lieu of random access iterators in standard algorithms that require sorted ranges, e.g. lower_bound, upper_bound, equal_range, and binary_search. This is useful when using these iterators in generic algorithms that internally call lower_bound/upper_bound/etc. Our implementation is attached. We are currently overloading std::lower_bound/... which is illegal. I propose introducing a boost::lower_bound/..., where we can ignore the C++ standard restriction, and where the standard implementation forwards to std::lower_bound. Runtime is O(log N), where N is the total number of elements in the container, rather than, as it would be optimal, the number of elements within the (sub)range on which the algorithm is called. The problem is that the red-black tree nodes do not store the tree level number, so we cannot find the parent node that encompasses the whole subrange in linear time. I am not sure this is practically relevant. In any case, using the sortedness of the tree rather than treating the iterators as arbitrary bidirectional iterators is a step forward. Any opinions?

GSM Programming
by master master 31 Dec '08

31 Dec '08

I want to program GSM mobile. GSM mobile will be connected to a PC via a serial port or usb cable or bluetooth etc. I will send commands from my PC and that command will operate the mobile like sending sms, calling numbers, etc. For this type of programming what libraries should I refer ??? Currently I am referring Asio for socket and threading. What else I need to refer ? Currently I am in analysis stage.

Interest in a Boost.JSON library?
by Kirit Sælensminde 31 Dec '08

31 Dec '08

As part of our web application framework (currently being ported from Windows to Linux) we have a JSON parser and library that might be of interest to a wider community as part of the Boost libraries. It uses a Spirit parser that deals correctly with embedded UTF-16 inside strings. The JSON blobs themselves are built on Boost.Variant and can store null, booleans, strings, int64_t, doubles and arrays & objects. The strings are our Unicode string implementation -- how this should be dealt with in Boost is an open question maybe only cleanly soluble when Boost has it's own proper Unicode string handling. A templated adapter layer could be used I think for both the string and the numeric types. There is also the internal implementation of the array and objects which could be moved to a policy based design. At the moment we use std::vector and std::map with boost::shared_ptr< json > as the value type. The JSON objects are immutable and use a thread safe CoW implementation when changes are required (handled through a separate jcursor object). One thing that is missing is a good EDSL for creating JSON blobs within C++ source code. The latest implementations is where we are using it to create an ACID JSON database and is here: http://svn.felspar.com/public/fost-base/branches/dbschema/Cpp/include/fost/… The parser itself is here: http://svn.felspar.com/public/fost-base/branches/dbschema/Cpp/include/fost/… There's a lot of room for improvement, but hopefully it's a good start.
