Library proposal - indexed_array
by Julien Blanc 12 Oct '23

12 Oct '23

Hi, I've written and released a (rather small) library which allows defining arrays with arbitrary index mechanisms (hence the name, indexed_array). This especially allows indexing with scoped enums, use non zero-starting indexes, or use sparse indexes. This is not a view, but an array in the sense that it owns the data, and provides the same guarantees and functionalities as std::array, such as triviality propagation, being able to reside in read-only program sections, etc. It also supports multidimensional indexing, and provides an indexed_span template class to access lower dimension content (which can be used outside indexed_array). Finally, it provides an opt-in safer way to initialize the array content, which is especially useful when using complex and/or changing indexing schemes (like based on externally generated files). The library is available here: https://github.com/Julien-Blanc-tgcm/indexed_array And the doc is here: https://julien-blanc-tgcm.github.io/indexed_array/ It requires C++17 and mp11, and has first-class support for describe-d enums. If there is some interest, i'd like to propose it for inclusion in boost. So i'm looking for people who would endorse it. Thanks and best regards, Julien

I'd like to merge a UB fix to master for Boost.MySQL. It affects only debug builds. Not critical, but may hit some platforms. Discovered during development of new code. https://github.com/boostorg/mysql/pull/136 Thanks, Ruben.

I think you’re right. The tag on the super project points to develop, and the one(s) on the sub-project all point to master. — Marshall

I'd like to merge a UB fix to master. It has (so far) not produced nasal demons, but is triggering checkers in projects that depend on Wave. https://github.com/boostorg/wave/pull/185 On Thu, Mar 16, 2023 at 8:38 AM Marshall Clow via Boost < boost(a)lists.boost.org> wrote: > The master branch is now open for bug fixes and documentation changes. > Other changes by release manager permission, as described in > > https://github.com/boostorg/wiki/wiki/Releases%3A-Beta-Merge-Policy < > https://github.com/boostorg/wiki/wiki/Releases%3A-Beta-Merge-Policy> > > The next deadline: On April 5th, master closes for all changes. > > As always, the calendar is at https://www.boost.org/development/ < > https://www.boost.org/development/> > > — Marshall > > > _______________________________________________ > Unsubscribe & other changes: > http://lists.boost.org/mailman/listinfo.cgi/boost >

Thanks for the tip, I've just run boostdep and results coincide with what there's already on the CML files. Marshall, OK to merge to master? Joaquín M López Muñoz

Maybe you should tag your library on GitHub, so it can be easily found, among the several which "compete" with it. Like those listed at the link below: https://github.com/topics/scope-guard?l=c%2B%2B One in particular (https://github.com/offa/scope-guard) refers to the WG21 paper. PS: Actually, I wonder whether Boost Libraries in general use GH tagging much.
