[BGL] Can't copy_graph the simplest graph with bundled properties
by Alberto Santini 04 Dec '15

The following code fails. Is it intended? If it is, how to copy a graph with bundled properties? http://coliru.stacked-crooked.com/a/b1017359126ab6f6 Thanks, AS

BGL, swap or move graphs
by Paolo Bolzoni 03 Dec '15

03 Dec '15

Dear list, I am writing a program where I create a graph first and I want to put it inside another class instance (type T). The idea is to keep the two steps separated as possible. Normally, sure-fire way was using swap. Inside the class T you create a default object and swap it with the real one on initialization; this avoids needless copies and just construct a small object. Nowadays, it is also possible to use moveable objects to even avoid that object creation. This is nice and I (think I) understood it, but it is possible to do anything like this with boost graphs? Graphs don't model Assignable, so swap is not possible, and I could not find anything about being Moveable either. Is there really no way to accomplish a swap or a move? I just have to create the graph in the beginning, and keep a reference, or pointer, to it? Cheers, Paolo

[Boost.Container] Need map supporting incomplete type and heterogeneous lookup
by dariomt＠gmail.com 30 Nov '15

30 Nov '15

Hi, I see that boost::container::map has support for incomplete types. However, it does not seem to support heterogeneous lookup. Is this correct? Are there plans to implement it? Is there anywhere in Boost a std::map-like associative container that supports incomplete types *and* heterogeneous lookup? Thanks!

[statechart]
by Ernesto Rodriguez Reina 30 Nov '15

30 Nov '15

Hi everyone, The statechart search for an event handler in post-order (children first then parent), however when we have orthogonal states involved then the behaviour I am experiencing is different. Let say we have an state X with two children [orthogonal] states Y and W. Assuming none of the handlers discard (or defer) an event, the handler for that event is called in the following order: Y, X, W, X. Note that the handler of X is called twice. The code in the following link shows that behaviour: http://coliru.stacked-crooked.com/a/14cb35ca23e586a5 If there something that I am missing? Best, Ernesto Rodriguez Reina

[Ublas] Bug in 1.59 in file boost/numeric/ublas/detail/concepts.hpp
by dariomt＠gmail.com 30 Nov '15

30 Nov '15

In the migration from Boost 1.55.0 to 1.59.0 I found a bug in Ublas. For instance, in 1.55.0 function OneElement() declared in boost/numeric/ublas/detail/concepts.hpp line 716 looks like this: template<> double OneElement (double) { return 1.; } However, in 1.59.0 I think there is a copy'n'paste typo, because the corresponding function (which has been refactored) looks like this: template<class T> T OneElement (T) { return T(0.0); } Please note that the latter version returns a *zero*, instead of a *one*. This same bug affects the vector overload of the function, but the matrix version looks correct (it returns identity_matrix). This looks like a copy'n'paste typo, from a similar function called ZeroElement(), that, of course, returns a zero. I'm not sure if there is time to get a fix for this in the 1.60 release... Regards!
