====

November 7, 2007 - Exception Library Accepted
Announcement:  http://lists.boost.org/boost-users/2007/11/31912.php

We need experienced review managers.  Please take a look at the list
of libraries in need of managers and check out their descriptions.  In
general review managers are active boost participants or library
contributors.  If you can serve as review manager for any of them,
email Ron Garcia or John Phillips, "garcia at cs dot indiana dot edu"
and "jphillip at capital dot edu" respectively.

A link to this report will be posted to www.boost.org.
If you would like us to make any modifications or additions to this
report before we do that, please email Ron or John.

If you're library author and plan on submitting a library for review
in the next 3-6 months, send Ron or John a short description of your
library and we'll add it to the Libraries Under Construction below.
We know that there are many libraries that are near completion, but we
have hard time keeping track all of them. Please keep us informed
about your progress.

Finite State Machines
---------------------
:Author: Andrey Semashev
:Review Manager: Martin Vuille
:Download: `Boost Sandbox Vault <http://tinyurl.com/yjozfn>`__

:Description:

   The Boost.FSM library is an implementation of FSM (stands for
   Finite State Machine) programming concept. The main goals of the
   library are:

   * Simplicity. It should be very simple to create state machines using
     this library.
   * Performance. The state machine infrastructure should not be
     very time and memory-consuming in order to be applicable in
     more use cases.
   * Extensibility. A developer may want to add more states to an
     existing state machine.  A developer should also be able to
     specify additional transitions and events for the machine with
     minimum modifications to the existing code.

Floating Point Utilities
------------------------
:Author: Johan Råde
:Review Manager: Need Volunteer
:Download:
   `Boost Sandbox Vault <http://boost-consulting.com/vault/index.php? 
directory=Math%20-%20Numerics>`__

:Description: The Floating Point Utilities library contains the  
following:

* Floating point number classification functions: fpclassify, isfinite,
    isinf, isnan, isnormal (Follows TR1)
* Sign bit functions: signbit, copysign, changesign (Follows TR1)
* Facets that format and parse infinity and NaN according to the C99
    standard (These can be used for portable handling of infinity and  
NaN
    in text streams).

Switch
------
:Author: Steven Watanabe
:Review Manager: Need Volunteer
:Download:
   `Boost Sandbox Vault <http://boost-consulting.com/vault/index.php? 
action=downloadfile&filename=mcs_units_v0.7.1.zip&directory=Units>`__

:Description:
   The built in C/C++ switch statement is very efficient. Unfortunately,
   unlike a chained if/else construct there is no easy way to use it  
when
   the number of cases depends on a template parameter. The Switch  
library
   addresses this issue.

Property Map (fast-track)
-------------------------
:Author: Andrew Sutton
:Review Manager: Jeremy Siek
:Download: http://svn.boost.org/svn/boost/sandbox/graph-v2
:Description:
   A number of additions and modifications to the Property Map Library,
   including:

   * A constant-valued property map, useful for naturally unweighted
     graphs.
   * A noop-writing property map, useful when you have to provide an
     argument, but just don't care about the output.
   * See
     `ChangeLog <http://svn.boost.org/trac/boost/browser/sandbox/ 
graph-v2/libs/property_map/ChangeLog>`__
     for details.

Graph (fast-track)
------------------
:Author: Andrew Sutton
:Review Manager: Jeremy Siek
:Download: http://svn.boost.org/svn/boost/sandbox/graph-v2
:Description:
A number of additions and modifications to the Graph Library,
including:

* Two new graph classes (undirected and directed) which are intended
    to make the library more approachable for new developers
* A suite of graph measures including degree and closeness
    centrality, mean geodesic distance, eccentricity, and clustering
    coefficients.
* An algorithm for visiting all cycles in a directed graph (Tiernan's
    from 1970ish). It works for undirected graphs too, but reports  
cycles
    twice (one for each direction).
* An algorithm for visiting all the cliques a graph (Bron&Kerbosch).
    Works for both directed and undirected.
* Derived graph measures radius and diameter (from eccentricity) and
    girth and circumference (from Tiernan), and clique number (from
    Bron&Kerbosch).
* An exterior_property class that helps hides some of the weirdness
    with exterior properties.
* runtime and compile-time tests for the new algorithms.
* a substantial amount of documentation
* Graph cores, implemented by David Gleich (@Stanford University)
* Deterministic graph generators - capable of creating or inducing
    specific types of graphs over a vertex set (e.g., star graph, wheel
    graph, prism graph, etc). There are several other specific types  
that
    could be added to this, but I haven't had the time just yet.

Forward (fast-track)
--------------------
:Author: Tobias Schwinger

:Review Manager: John Torjo

:Download: http://boost-consulting.com/vault/index.php? 
&direction=0&order=&directory=X-Files

:Description: A brute-force solution to the forwarding problem.

Singleton (fast-track)
----------------------
:Author: Tobias Schwinger

:Review Manager: John Torjo

:Download: http://boost-consulting.com/vault/index.php? 
&direction=0&order=&directory=X-Files

:Description: Three thread-safe Singleton templates with an
   easy-to-use interface.

Factory (fast-track)
--------------------
:Author: Tobias Schwinger

:Review Manager: John Torjo

:Download: http://boost-consulting.com/vault/index.php? 
&direction=0&order=&directory=X-Files

:Description: Generic factories.

Lexer
-----
:Author: Ben Hanson

:Review Manager: Need Volunteer

:Download: http://boost-consulting.com/vault/index.php? 
action=downloadfile&filename=boost.lexer.zip&directory=Strings%20-% 
20Text%20Processing&

:Description:

   A programmable lexical analyser generator inspired by 'flex'.
   Like flex, it is programmed by the use of regular expressions
   and outputs a state machine as a number of DFAs utilising
   equivalence classes for compression.

Thread-Safe Signals
-------------------
:Author: Frank Hess

:Review Manager: Need Volunteer

:Download: http://www.boost-consulting.com/vault/index.php? 
&direction=0&order=&directory=thread_safe_signals

:Description: A thread-safe implementation of Boost.signals that
   has some interface changes to accommodate thread safety, mostly with
   respect to automatic connection management.

Logging
-------
:Author: John Torjo

:Review Manager: Need Volunteer

:Download: http://torjo.com/log2/

:Description:
   Used properly, logging is a very powerful tool. Besides aiding
   debugging/testing, it can also show you how your application is
   used. The Boost Logging Library allows just for that, supporting
   a lot of scenarios, ranging from very simple (dumping all to one
   destination), to very complex (multiple logs, some enabled/some
   not, levels, etc).  It features a very simple and flexible
   interface, efficient filtering of messages, thread-safety,
   formatters and destinations, easy manipulation of logs, finding
   the best logger/filter classes based on your application's
   needs, you can define your own macros and much more!

Flyweight
---------
:Author: Joaquín M López Muñoz

:Review Manager: Need Volunteer

:Download: http://www.boost-consulting.com/vault/index.php? 
action=downloadfile&filename=flyweight.zip&directory=Patterns

:Description: Flyweights are small-sized handle classes granting
   constant access to shared common data, thus allowing for the
   management of large amounts of entities within reasonable memory
   limits. Boost.Flyweight makes it easy to use this common
   programming idiom by providing the class template flyweight<T>,
   which acts as a drop-in replacement for const T.

Unordered Containers
--------------------
:Author: Daniel James

:Review Manager: Need Volunteer

:Download: http://www.boost-consulting.com/vault/index.php? 
action=downloadfile&filename=unordered.zip&directory=Containers

:Description: An implementation of the unordered containers specified
   in TR1, with most of the changes from the recent draft standards.

Libraries under development
===========================

Dataflow
--------
:Author: Stjepan Rajko

:Description:
   The Dataflow library provides generic support for data
   producers, consumers, and connections between the two.  It also
   provides layers for several specific dataflow mechanisms, namely
   Boost.Signals, VTK data/display pipelines, and plain
   pointers. The Dataflow library came out of the Signal Network
   GSoC project, mentored by Doug Gregor.

:Status:
   I am polishing the Dataflow library for submission, and am expecting
   to add it to the review queue in the next couple of months.
   I am currently ironing out some faults in the design of the library,
   filling in missing features, and testing it on / adapting it to
   different dataflow mechanisms (currently VTK and soon
   Boost.Iostreams).  As soon as I'm pretty sure that things are going
   the right way, I'll submit this to the review queue while I do the
   finishing touches.

Constrained Value
-----------------
:Author: Robert Kawulak

:Download:
   http://rk.go.pl/f/constrained_value.zip

   http://rk.go.pl/r/constrained_value (Documentation)

:Description:
   The Constrained Value library contains class templates
   useful for creating constrained objects. The simplest example
   of a constrained object is hour. The only valid values for an hour
   within a day are integers from the range [0, 23]. With this library,
   you can create a variable which behaves exactly like int, but does
   not allow for assignment of values which do not belong to the
   allowed range. The library doesn't focus only on constrained
   objects that hold a value belonging to a specified range (i.e.,
   bounded objects). Virtually any constraint can be imposed using
   appropriate predicate. You can specify what happens in case of
   assignment of an invalid value, e.g. an exception may be thrown or
   the value may be adjusted to meet the constraint criterions.

:Status: I'm planning to finish it in 1-2 months.

Please let us know of any libraries you are currently
developing that you intend to submit for review.
