missing locale/info.hpp
by markus.rauber＠bluewin.ch 20 Oct '11

20 Oct '11

Hi in your documentation you mention the availability of info.hpp (located in /boost/locale) I've just downloaded the latest 1.47 release and there's no such "locale" subdirectory and no info.hpp file containing a <locale> include statement. I'd like to use the language settings provided with this header file. Where can it be found? Where can the corresponding library be found? Thanks for your feedback Markus

using nabble to read/write on Boost ML
by lcaminiti 20 Oct '11

20 Oct '11

Hello all, I use Nabble to read/write Boost emails but it puts special HTML instead of the template parenthesis: template<typename T> Other Nabble users (if any), is there a way to configure Nabble to not do this? If not, is there another web-based tool (a side from my personal gmail) I can use to view and reply Boost emails? Thanks a lot. --Lorenzo -- View this message in context: http://boost.2283326.n4.nabble.com/boost-using-nabble-to-read-write-on-Boos… Sent from the Boost - Dev mailing list archive at Nabble.com.

Adding "[utility]" to your subject would have helped to focus attention on the affected library. Boost.Utility has no single maintainer, so adding that to the subject will attract attention from the interested parties and your asking about the bug reported six months ago will help to increase attention. You might want to add your own details to the Trac report, including whether the proposed patch fixes your problem. (If it did, it should encourage the maintainers to accept the patch.) _____ Rob Stewart robert.stewart(a)sig.com Software Engineer using std::disclaimer; Dev Tools & Components Susquehanna International Group, LLP http://www.sig.com ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.

Boost.Locale was accepted into Boost this past spring (see http://www.boost.org/community/review_schedule.html for details). It has not yet been made part of a release (as can be seen from http://www.boost.org/doc/libs/, which you can access from boost.org's Libraries link.) FYI: It is also helpful to include the library name in square brackets in your subject to ensure the library author/maintainer discovers it (see http://www.boost.org/community/policy.html#subject-line) Conventionally, the library name is rendered in lower case. I have done so in my reply, so Artyom may well have more details to offer you. _____ Rob Stewart robert.stewart(a)sig.com Software Engineer using std::disclaimer; Dev Tools & Components Susquehanna International Group, LLP http://www.sig.com ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.

RFC: A better shared_array

Hi, The current shared_array doesn't keep track of size. This greatly decreases it's usefulness. So I wrote a variant that does: http://pastebin.com/wkdLVqM1 Any interest in such a variant? Olaf

How can I contribute?
by Andrzej Krzemienski 19 Oct '11

19 Oct '11

Hi, I am not well familiar with Boost procedures, so I apologize if my question is silly. I found a bug (or a missing feature) in template boost::value_initialized. I found that a bug report and the proposed resolution are already there in BoostTrac: https://svn.boost.org/trac/boost/ticket/5483. Is there a way I could help speed the process of getting it fixed up? Can people from outside commit changes to Boost trunk? Regards, &rzej

Re: [boost] Interest in StaticVector - fixed capacity vector

This is true *for every standard container* (which supports the corresponding operation, of course). You want to *silently* break that consistency. That will lead to buffer overrun bugs, which we know are hard to debug and I'm not saying we don't need the unchecked functionality. I'm saying it should never be spelled p-u-s-h-_-b-a-c-k, i-n-s-e-r-t, r-e-s-i-z-e, etc. (which is one of the reasons I'm arguing against making it policy based). I'm strongly opposed to any solution that uses the same function signatures as the standard containers that isn't as safe and easy to call as the ones in the standard containers. -- Nevin ":-)" Liber <mailto:nevin@eviloverlord.com> (847) 691-1404

[context] interface to query remaining stack space
by Charlls Quarra 19 Oct '11

19 Oct '11

Hi All, is there a easy way to query the remaining stack space in a given context? assuming the context is running, i can check the address of a stack dummy variable, but i don't see a way to query the top address of the stack. One could do this by storing that top address before creating the context, but i was wondering if there is already an interface that i'm missing? thanks

Boost.Integer makes it > possible to select a suitable type. Sorry for the duplicate email, but my other email seemed to get lost in the shuffle. I know its been a while since I sent my first emails regarding StaticVector, but I have fixed some of the issues others pointed out. - I added a benchmark based on a move benchmark found on C++Next, that shows StaticVector outperforming vector by about 30%, which seems reasonable since there is no dynamic allocation. - I believe I've resolved the StaticVector alignment using type_traits' aligned_storage, as suggested by Nevin Liber. - I've also added the use of Boost.Integer to select the smallest possible type to track the size of the vector given its capacity, as suggested by Phil Endecott. The Implementation is available at: https://github.com/ahundt/Boost.StaticVector Anyone still have additional thoughts or interest in this? Cheers! Andrew Hundt
