Boris, there are lots of things in this thread that I disagree with. However, I don't have either the time or the energy to explain them all and work on my own Library in which I have already invested 3 years work.

Some of us have not left but are working quietly in the background. predominately because we have seen the same kinds of discussions happen over and over. The main reason we do not have a socket lib is that even to produce a basic lib supporting blocking, non-blocking and signal driven is that it is a very big undertaking to produce good type safety, and be able to cope with the richness of the BSD socket API functionality. /ikh

The design is complete ( I hope ) after many revisions and I am currently implementing it again. Basic concepts supported are: address socket select fd_set socket_options Protocol support is for IPv4 and IPv6 with unicast, broadcast, and multicast. additionally, I have support for routing, raw, and data link layer sockets. Initial implementation will be for gcc and Linux only and once I have had a preliminary review I'll add Intel on Linux , and GCC on Windows Impl. /ikh

[mpl] BOOST_MPL_AUX_ASSERT_NOT_NA problem
by Daniel Wallin 13 Apr '05

13 Apr '05

This problem is showing up in the Parameter library: http://tinyurl.com/4tmy7 I think this is a problem with the assert mechanism in MPL, because if you change boost/mpl/aux_/na_assert.hpp so that it always uses BOOST_STATIC_ASSERT instead of BOOST_MPL_ASSERT_NOT the Parameter tests compile. -- Daniel Wallin

Hi, As you've noticed I added Boost.Test examples into status/Jamfile (as it was recommended to me).Unfortunately I do not see any results on status pages. Any help? Gennadiy

Hi Doug, I would be curious to hear your thoughts on the proposal I posted to the sandbox (network.zip). The complete implementation (including URL class, thread pooling, load balancing, etc.) was < 9000 lines and that includes tons of comments (see network.hpp for a frame of reference). I wrote it from scratch in 3 weeks (once the design was finalized). Or rephrased from a previous message: it's not the technical challenges that take all the time; it's the design process ;) Best, Don --- Douglas Gregor <doug.gregor(a)gmail.com> wrote: > I think the scope of this library is insane.

Regex-User: ISBN validation
by Detlef 12 Apr '05

12 Apr '05

Hi, we need to validate ISBN. With another REGEX-implementation we uses (?=.{13})\d{1,5}( |\-)\d{1,7}\1\d{1,6}\1(\d|X). But this seem not to work. Only the shorter version "\d{1,5}( |\\-)?\\d{1,7}\\1\\d{1,6}\\1(\d|X)" works, but how to check the 13 digits? Thanx in advanced Detlef

Hi all, It seems, that there is a problem in the cw9.4 configuration. BOOST_HAS_SLIST macro is defined, but no <slist> header is present. See: http://tinyurl.com/3rv9h Any idea what to do? Regards, Pavol

[config] BOOST_GCC
by Gennadiy Rozental 12 Apr '05

12 Apr '05

Why don't we have single BOOST_GCC macro which defines version of gcc compiler. In numerous places around boost we need to check for specific versions on gcc and required to use complex expressions involving up to 3 gcc variables. Gennadiy
