1. MANAGEMENT SUMMARY
1.1 JTC1/SC22/WG21 STATEMENT OF SCOPE
Development and maintenance of ISO/IEC Standards related to the
programming language C++.
1.2. PROJECT REPORT
1.2.1. COMPLETED PROJECTS
JTC 1.22.32- Programming Language C++ - This project was delivered by the
publishing of ISO/IEC 14882:1998 (first standard) and :2003 (minor revision).
JTC 1.22.18015 Information Technology - Programming Languages Technical
Report on C++ Performance (Technical Report Type 3)
JTC 1.22.19768 Information Technology - Programming Languages Technical
Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882)
1.2.2. PROJECTS UNDERWAY
JTC 1.22.32 - Work is in progress on the first major revision.
JTC 1.22.24733 Information Technology - Programming Languages Technical
Report of Type 2 on Extensions for the programming language C++ to support
decimal floating point arithmetic
JTC 1.22.29124 Programming Language C++ - International Standard on
Special Math Functions
1.2.3. CANCELLED PROJECTS
Two projects were cancelled at the September 2008 SC22 Plenary, at the
request of WG21:
- JTC 1.22.24737 Information Technology - Programming Languages Technical
Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882)
- JTC 1.22.29117 Programming Language C++ - Modules
1.2.4. COOPERATION and COMPETITION
Where appropriate, WG21 has established liaisons with other SC22 and SC22
liaison organizations' working groups. There is no direct competition with
any other current SC22 working group. Related work is being done in
SC22/WG14 (C) with broad WG21 liaison.
2. PERIOD REVIEW
2.1. MARKET REQUIREMENTS
ISO C++ remains a widely-used foundation technology, well-received in
the marketplace. WG21 is developing a revision of ISO 14882. Once that
revision is complete, WG21 intends to continue work on a second Technical
Report on C++ Library Extensions.
2.2. ACHIEVEMENTS
JTC 1.22.18015 Information Technology Programming Languages Technical
Report on C++ Performance (Technical Report Type 3) was published in 2005.
JTC 1.22.19768 Information Technology - Programming Languages Technical
Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882)
was published in 2006.
JTC 1.22.32 - A committee draft was ballotted in 2008-9.
2.3. RESOURCES
WG21 meets three times per year in co-located technical sessions with the
US committee J16. For most of the past decade, WG21 has timed its technical
sessions to catenate with WG14, allowing those technical experts that
would like to attend both technical sessions the opportunity to do so.
(The convener of WG21 wishes to thank the convener of WG14 for his
much-appreciated efforts at harmonious liaison. This catenation continues
periodically, although no longer for every meeting as WG21 and WG14 now
have a different meeting frequency.)
Fifteen countries participate by attending these meetings or by being
involved in the technical discussions that take place over the
reflector. The countries are: Austria, Canada, Denmark, Finland, France,
Germany, Ireland, Japan, Netherlands, Republic of Korea, Russia, Sweden,
Switzerland, United Kingdom, and United States of America. WG21 has been
monitoring the cross-language standards activities, and made use of the
ISO/IEC JTC1/SC22 guidelines on extended characters.

3. FOCUS NEXT WORK PERIOD
3.1. DELIVERABLES
Technical work on a major revision of JTC 1.22.14882 is underway, and WG21
expects to issue a disposition of comments on its first CD, along with a
second CD, after its September 2009 meeting.
Technical work on JTC 1.22.24733 Information Technology - Programming
Languages Technical Report of Type 2 on Extensions for the programming
language C++ to support decimal floating point arithmetic (based on ISO/IEC
14882) is underway with liaison coordination with WG14's similar work item.
WG21 expects to issue a DTR after its September 2009 meeting.
Technical work on JTC 1.22.29124 Programming Language C++ - Special Math
Functions is complete. WG21 is awaiting the result of FCD balloting.
3.2. STRATEGIES
WG21 members have been meeting in subgroups and coordinating work between
meetings via e-mail reflectors and the wiki to develop responses to the
National Body comments on the first CD, which are extensive.
3.3. RISKS
Compiler developers have not implemented new language features as rapidly
as projected last year, so there is growing concern about maintaining both
the current feature list and schedule. This will be a topic of discussion
at the Frankfurt meeting in July. The risks are that either the current
feature list or the schedule will have to be compromised to produce an
acceptable revision of the C++ Standard.
3.4. OPPORTUNITIES
Nothing new to report.
3.5. WORK PROGRAM PRIORITIES
Once the revision of 14882 is complete, WG21 intends to continue
work on some or all of the following:
- A technical report on C++ Library Extensions. This will be the
second "library extensions TR."
- A replacement project for the cancelled JTC 1.22.29117
Programming Language C++ - Modules.
4. OTHER ITEMS
4.1. POSSIBLE ACTION REQUESTS AT FORTHCOMING PLENARY
None are anticipated.
4.2 PROJECT EDITORS
The following individuals have been appointed project editors and
backup Project editors:
JTC1.22.32, Programming Language C++:
Pete Becker (Project Editor)
Lawrence Crowl (Backup Project Editor)
JTC1.22.24733, Technical Report on Extensions to support decimal floating
point arithmetic
Robert Klarer (Project Editor)
Pete Becker (Backup Project Editor)
JTC1.22.29124 Programming Language C++ - Special Math Functions
Walter Brown (Project Editor)
Pete Becker (Backup Project Editor)
4.3 ELECTRONIC DOCUMENT DISTRIBUTION
WG21 has conducted much of its detailed technical discussion using the
email reflector provided by the UK Association for C and C++ Users (ACCU).
WG21 also has an FTP and Web site at www.open-std.org/jtc1/sc22/wg21
provided by courtesy of Keld Simonsen.
WG21 uses a secure wiki maintained by Dinkumware, Ltd. This secure wiki
is used for quick exchange of documents during and between meetings.
WG21 is now providing all the appropriate committee documents on the
Committee Web site, eliminating the need for paper mailings.
