Boost Inspection Report Run Date: 16:05:46 UTC, Saturday 16 June 2007 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11452 files scanned 909 directories scanned (including root) 163 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 3 invalid urls 71 broken links 21 unlinked files 22 file/directory names issues 2 files with tabs 9 violations of the Boost min/max guidelines 35 usages of unnamed namespaces in headers (including .ipp files) Summary: archive (3) bind (1) boost-root (1) build (1) date_time (1) doc (2) filesystem (3) graph (3) iostreams (2) lambda (3) math (8) more (4) mpl (4) multi_array (2) ptr_container (1) python (8) regex (1)

[FSM] Self-events feature interest poll
by Andrey Semashev 16 Jun '07

16 Jun '07

Hello, I'd like to know if there is any interest in a new feature addition to the Boost.FSM library, been proposed for a review some time ago. The feature is an ability to post events to the state machine from within its state. These events would be delivered after the control returns from on_process event handler and would be delivered just like if were sent from outside the FSM. This allows to introduce a set of internal FSM events that may be used to perform complex processing of external events in different states. The downside is that the feature is apparently in conflict with ability to return something from the FSM's process method, so the return type will be forced to be void. Is this feature worth further thinking of and implementing? PS: The current version of Boost.FSM is still available in the Vault: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam…

[proto] another problem w/ terminal matching
by Maurizio Vitale 16 Jun '07

16 Jun '07

Eric, I've found more about the root problem in my code. A pattern for a terminal was not matching and the thus the transform for unary_expr was applied. In the code included, I define a class, K_aux, which inherits from meta_expression<typename proto::terminal<K<mpl::int_<N> >, Normally, objects of type K_aux match a pattern terminal<K<proto::_> >. I'm still fuzzy on why two layers of the type are skipped, but I'm fine with it. Now, if K_aux defines a type named type (e.g. effectively becoming a nullary metafunction) the pattern doesn't match anymore. If this is intentional or unavoidable it should be mentioned in the docs. In boldface. Btw, the entire exercise is to get real compile time constants. I can change the name of the typedef'd type and use code similar to this, but if there was a better way I'd liek to hear.

I'll see if John Phillips, who is handeling the review of Eric's Time series library, wants to get the ball rolling. I'll start the ticket and he can close it.

Which might be much less acceptable, than >> silently rejecting a library proposal, IMHO. The "so-called" silent rejection was no such thing. I did a search in the mailing against the mailing list to find out what this was all about. As far as I can tell, the person in question posted one message to the group, that he was willing to volunteer to be a review manager. I couldnt find a second post, let alone a third posting. In any event, I missed his posting(s) and as I never received a direct email from him, I was not aware that he had volunteered.

Re: [boost] [fusion] unpack into constructor?

I can't tell my looking at the docs. I looked at the stuff in >fusion/functional and couldn't find what I was looking for. I don't think we've got anything that supports this directly at the moment. Is the sort of thing you are looking for? fused_ctor<T> fc; T t = fc(sequence); Where fused_ctor::operator()(Seq const&) breaks up the sequence into args for the T ctor. If thats the sort of thing, I think we should have something like this, I can cook something up over the next few days, once I've worked through a bit of my backlog :) Of course I may have missed an existing feature, which my co-authors might pick me up on...

[proto] grammar matching issue
by Maurizio Vitale 15 Jun '07

15 Jun '07

This one took me a long time to understand, and now that I think I understand it, I'm pretty sure I don't like Apparently (at least in the situation shown below, with user defined domain and expressions) unary_expr matches terminal< >. This was surprising to me because I was working under the assumption that unary_expr matched only bona-fide unary C++ operators. Ordering should have solved the problem in my real code, so I still have investigations to do. In my case I need to match both things, but threat the case separately (e.g. a terminal<foo> will be transfromed differently from a terminal<bar> and even more differently from ++a). Now, I can certainly (I think, not tested) wrap unary_expr in a proto::and_ that tests the tag, but it seems such a common occurrence that I'd like it to be the default proto behaviour. Unless I'm doing something stupid.

Boost Asio error

Hello, I've just discovered boots::asio. Looks good but got a small problem. I'm basing my client on the chat_client example, but having a problem. In the example, command line arguments are passed to the chat_client specifying server details. My question is, what is the format of the argv in the example? I have modified things a little to fit into my system, but am not sure what to pass the chat_client class. I have tried passing "localhost", but am still getting an error here: boost::asio::io_service io_service; tcp::resolver resolver(io_service); tcp::resolver::query query(DEFAULT_SERVERNAME); // DEFAULT_SERVERNAME = '127.0.0.1' tcp::resolver::iterator iterator = resolver.resolve(query); // <<< error here, in 'implementation' - not defined! m_connector = boost::shared_ptr<CConnector>( new CConnector( io_service, iterator ) ); // <<< this is just a version of chat_client.hpp Sure I am missing something simple.... thanks for the advice Simon -- http://www.simonpickles.com --- http://www.squirtualreality.com
