[review] Fast track formal review of Forward library begins today

Hi all,

The formal review of the Boost.Functional/Forward library, proposed by 
Tobias Schwinger, begins today :

Boost.Functional/Forward provides decorator function objects to have an 
n-ary,
generic function object accept both RValues and mutable LValues.

An exponential number of overloads is needed with C98, so redundant 
solutions are highly undesirable.
Functional/Forward is a reusable implementation asking to live in a 
central place in Boost.

Download it from here:

http://www.boost-consulting.com/vault/index.php?action=downloadfile&filename=forward.zip&directory=X-Files&
http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directory=X-Files

The documentation is included in the .zip file, in the usual place: 
forward/libs/functional/forward/doc/html/index.html

What to include in Review Comments
==================================

Your comments may be brief or lengthy, but basically the Review Manager
needs your evaluation of the library. If you identify problems along
the way, please note if they are minor, serious, or showstoppers.

Here are some questions you might want to answer in your review:

[review] Boost.Functional/Forward - result

Hi all,

I'm happy to announce that The Boost.Functional/Forward library has been 
accepted into Boost. Congrats to Tobias for a great lib!

Summary:
5 reviews, all positive.

Suggestions for improvement:
- Automatically detect if the compiler supports variadic templates and
  rvalue references and use those instead. This can be a useful
  portability utility when such compilers become more common.
- It should use compressed_pair to store the wrapped function object to
  take advantage of EBO.
- more tweakable parameters for specific uses - like, arity 3 for 
function X,
  and arity 5 for function Y
- Docs: add more material explaining the forwarding problem
- Docs: should be explicitly specified that the wrapped function
  object must be result_of compatible
- Docs: A discussion of the impact of the library on compile time 
(especially
  with high values of N)

Best,
John

[review] Gentle reminder - Fast track formal review of Boost.Functional/Factory will begin December 17

Hi all,

This is a gentle reminder of the Boost.Functional/Factory review, about 
to start next Monday.

Factories are callback mechanisms for constructors, so we provide two 
function objects, boost::value_factory and boost::factory, that 
encasulate object construction through direct application of the 
constructor or operator new, respectively. These templates make other 
facilities that operate on function objects (such as standard 
algorithms, Boost.Bind, Boost.Function, or Fusion functional adapters) 
applicable to constructors.

Get it from here:
http://www.boost-consulting.com/vault/index.php?action=downloadfile&filename=factory.zip&directory=X-Files&

Best,
John

BoostCon 2008: May 4-9


The 2nd annual Boost Conference has been scheduled for May 4-9
2008.  Please save the date!  Registration should open sometime in the
next week.

If you want to stay at the Aspen Meadows (highly recommended as it is
within walking distance of the conference venue and was the site of
great after-hours discussions in '07), it's especially important this
year that you book your rooms early.  Since, unlike last year, Aspen's
airport will be open this May, demand for rooms has been heavy.  In
fact, the following week, which we tried to get, was snapped up by
another group before we even had a chance to catch our breath, just
weeks after BoostCon'07 ended.  

We'll be working hard on getting the program together for 2008 over
the coming weeks.  We hope to include many more Boost authors and
contributors, and build in several more intensive library-specific
sessions, to make 2008 better than ever.

Please send any questions to the BoostCon planning committee at:

   boostcon-plan <at> lists.boost-consulting.com

Those of you who didn't make it to BoostCon'07 may want to have a look
at the photo gallery at http://boostcon.com/community/photos, peruse
the 2007 program at http://boostcon.com/program, and check out the two
trip reports mentioned here:
http://boostcon.com/news/2007/Jul/16/yet-another-trip-report.

See you in Aspen!

-- The BoostCon Planning Committee

[review] Formal Fast-Track review of the Boost.Functional/Factory library begins today

Hi all,

Today starts the formal Fast-Track review of the Boost.Functional/Factory library.

*Description*

Factories are callback mechanisms for constructors, so we provide two 
function objects, boost::value_factory and boost::factory, that 
encasulate object construction through direct application of the 
constructor or operator new, respectively. These templates make other 
facilities that operate on function objects (such as standard 
algorithms, Boost.Bind, Boost.Function, or Fusion functional adapters) 
applicable to constructors.

What to include in Review Comments
==================================

Your comments may be brief or lengthy, but basically the Review Manager
needs your evaluation of the library. If you identify problems along
the way, please note if they are minor, serious, or showstoppers.

Here are some questions you might want to answer in your review:

* What is your evaluation of the design?
* What is your evaluation of the implementation?
* What is your evaluation of the documentation?
* What is your evaluation of the potential usefulness of the library?
* Did you try to use the library? With what compiler?
   Did you have any problems?
* How much effort did you put into your evaluation?
   A glance? A quick reading? In-depth study?
* Are you knowledgeable about the problem domain?

And finally, every review should answer this question:

* Do you think the library should be accepted as a Boost library?
   Be sure to say this explicitly so that your other comments
   don't obscure your overall opinion.

Best,
John Torjo

[review][unordered] Unordered accepted

Hi to all,

The Unordered library submitted by Daniel James has been *accepted* into 
Boost. Thanks to all reviewers and all who contributed to the library 
before the review.

We've received 8 reviews (Thosten Ottosen, Chun Ping Wang, Hervé 
Brönnimann, John Torjo, Cromwell Enage, Jamie Allsop, Graham Mark and 
Paul Bristow), and all were positive (since Chun's only complain was 
packaging and his ratings were all above 7 out of 10). Darren Cook 
privately sent me a positive mini-review (attached below). If I've 
missed any review, please let me know.

I plan to write a post this weekend with a summary of 
requests/suggestions and Daniel's replies.

Congrats Daniel!

Regards,

Ion

Hi Ion,
Not critical but the images seem to be missing. E.g. on
http://igaztanaga.drivehq.com/unordered/unordered/buckets.html

If I find time I will try out the library and write a review in the
week, but here is a mini-review (feel free to forward to the list - I'm
not subscribed at the moment):

Documentation:
  * Fine

  * The concrete examples of how to use a custom type, and a custom hash
function, and do everything in portable TR1, are wonderful - I've
searched before and never been able to find something as clear as this
seems to be.

  * In Table 1.4: "No equivalent. No idea why." is not very Boost-like
  :-) . Isn't the reason simply that there is no ordering in hash
containers, so therefore no ordering function?

 > > * What is your evaluation of the potential usefulness of the library?
 > > * Do you think the library should be accepted as a Boost library?

Yes. It is essential it gets into Boost as rapidly as possible; in fact
I think it should be released as a patch to the current release. Having
all of TR1 except for the hashed containers is a nasty red pimple on the
otherwise very handsome nose of Boost.

In particular, Visual C++ *still* does not ship with TR1 ("no plans
until 2009" was the rumour I found), so anyone wanting to ship portable
code is relying on Boost. And, at least for me, unordered_map is the
single most useful library in TR1.

Darren
