C++ Library Working Group Status Report (Post San Francisco 2008)

This paper presents a quick summary of all papers submitted to WG21 for consideration by the Library Working Group, with an indication of their progress towards inclusion in the next C++ Standard or future TRs. It is based on the pre-San Francisco 2008 mailing, with additional documents made available during the San Francisco meeting itself.

There is a minimal crossover with the State of Evolution paper N2869 where concurrency related topics tend to cross the Core/Library divide, and till now have been largely handled by the Evolution Working Group.

Note on progress

This document represents all papers that have been adopted for C++0x CD1. Following the San Francsico meeting it is expected that the current working paper, as ammended by the papers highlighed in this document, shall be forwarded by the SC22 secretariat for ballotting as a CD for the next revision of the C++ standard. As such, C++0x is now feature complete and the only expected work remaining is resolution of ballot comments and defects until we poll for FCD, provisionally toward the end of 2009.

Note on earlier documents

Since the author started tracking library papers, a number of documents have been handed to ISO for ballotting. The table below presents the last draught of these documents, together with a paper describing the history of papers contributing to that document, along with its current status.

Much of the library development that has gone into the next standard occurred during the development of Library TR1. It might be helpful to refer to the history of that document when looking for the evolution of the C++0x standard library below.

Key to the tables

Papers have been grouped in a self-selecting manner as either new components or updates. There is usually a series of papers describing a proposal's evolution, and only the right-most paper is deemed current. Papers are listed in the order or the clause they apply to, or is most relevant. Exceptions are the updates for language features, which generally apply across the whole library.

Note that while the deadline for new proposals for C++0x is long past, work continues on TR2 and beyond, so new submissions remain welcome.

Proposals in a green font have advanced a category since the last meeting, those in red have moved back, while those in yellow are new or have been updated since the last meeting.

Proposals with a green background have been highlighted as the features that will be delivered in the next version of the standard in the Registration Document.

A Note on Technical Reports

As there will be a continuing series of TRs there is no hard cut-off date for when proposals will be accepted. Once a proposal is ready it will ship as part of the next available TR. There will be natural 'quiet periods' where proposals are accumulating with little attention though, as work focusses on shipping accepted proposals in the next standard, or the next TR.
