+
+
+ Welcome to Boost.org!
+
+
+
+ Boost provides free peer-reviewed portable C++ source libraries.
+ We emphasize libraries that work well with the C++ Standard Library.
+ Boost libraries are intended to be widely useful, and usable across a
+ broad spectrum of applications. The Boost
+ license encourages both commercial and non-commercial use.
+ We aim to establish "existing practice" and provide reference
+ implementations so that Boost libraries are suitable for eventual
+ standardization. Ten Boost libraries are already included in the C++ Standards
+ Committee's Library Technical Report ( TR1)
+ as a step toward becoming part of a future C++ Standard. More Boost
+ libraries are proposed for the upcoming TR2.
+ Getting started: Boost works on almost any modern operating system,
+ including UNIX and Windows variants. Follow the Getting Started Guide to download and
+ install Boost. Popular Linux and Unix distributions such as Fedora, Debian, and NetBSD include pre-built Boost packages.
+ Boost may also already be available on your organization's internal web
+ server.
+ Background: The Background Information
+ page has introductory material to help those educating their
+ organization about Boost.
+ Participation
+
+
+
+ Although Boost was begun by members of the C++ Standards Committee
+ Library Working Group, participation has expanded to include thousands of
+ programmers from the C++ community at large.
+ If you are interested in participating in Boost, please join our main
+ developers mailing list.
+ Discussions are highly technical, and list members are encouraged to
+ participate in formal reviews of proposed libraries. There is also a users mailing list, and several project specific lists.
+ Both the main Boost developers list and the users list are also
+ accessible as newsgroups.
+ Latest News

+
+
+ May 14, 2007 - BoostCon'07 starts today
+ The long anticipated BoostCon'07 finally starts today. Promising to be the
+ main face-to-face event for all things Boost, BoostCon'07 opens the door to
+ your C++ future.
+ May 12, 2007 - Version 1.34.0
+ New Libraries
+
+ - Foreach
+ Library: BOOST_FOREACH macro for easily iterating
+ over the elements of a sequence, from Eric Niebler.
+
- Statechart Library:
+ Arbitrarily complex finite state machines can be implemented in easily
+ readable and maintainable C++ code, from Andreas Huber.
+
- TR1
+ Library: An implementation of the C++ Technical Report on
+ Standard Library Extensions, from John Maddock. This library does not
+ itself implement the TR1 components, rather it's a thin wrapper that
+ will include your standard library's TR1 implementation (if it has one),
+ otherwise it will include the Boost Library equivalents, and import them
+ into namespace
std::tr1. Highlights include: Reference
+ Wrappers, Smart Pointers, result_of, Function Object Binders,
+ Polymorphic function wrappers, Type Traits, Random Number Generators and
+ Distributions, Tuples, Fixed Size Array, Hash Function Objects, Regular
+ Expressions, and Complex Number Additional Algorithms.
+ - Typeof
+ Library: Typeof operator emulation, from Arkadiy Vertleyb and
+ Peder Holt.
+
- Xpressive
+ Library: Regular expressions that can be written as strings
+ or as expression templates, and that can refer to each other and
+ themselves recursively with the power of context-free grammars, from
+ Eric Niebler.
+ Updated Libraries
+
+ - Assign
+ Library:
+
+ - Support for
ptr_map<key,T> via the new function
+ ptr_map_insert()
+ - Support for initialization of Pointer Containers when the
+ containers hold pointers to an abstract base class.
+ - Date_time
+ library:
+
+ - Support for new US/Canada timezone rules and other bug fixes. See
+ Change History
+ for details.
+ - Filesystem Library:
+ Major upgrade in preparation for submission to the C++ Standards
+ Committee for TR2. Changes include:
+
+ - Internationalization,
+ provided by class templates basic_path,
+ basic_filesystem_error, basic_directory_iterator, and
+ basic_directory_entry.
+
- Simplification
+ of the path interface by eliminating special constructors to identify
+ native formats.
+
- Rationalization
+ of predicate function design, including the addition of several new
+ functions.
+
- Clearer specification by reference to POSIX, the ISO/IEEE
+ Single Unix Standard, with provisions for Windows and other operating
+ systems.
+
- Preservation of
+ existing user code whenever possible.
+
- More
+ efficient directory iteration.
+
- Addition of a recursive
+ directory iterator.
+ - Function
+ Library: Boost.Function now implements a small buffer
+ optimization, which can drastically improve the performance when copying
+ or constructing Boost.Function objects storing small function objects.
+ For instance,
bind(&X:foo, &x, _1, _2) requires no
+ heap allocation when placed into a Boost.Function object.
+ - Functional/Hash
+ Library
+
+ - Use declarations for standard classes, so that the library doesn't
+ need to include all of their headers
+
- Deprecated the <boost/functional/hash/*.hpp>
+ headers.
+
- Add support for the BOOST_HASH_NO_EXTENSIONS macro, which
+ disables the extensions to TR1
+
- Minor improvements to the hash functions for floating point
+ numbers.
+ - Graph
+ Library:
+
+
- MultiArray
+ Library: Boost.MultiArray now by default provides
+ range-checking for
operator[]. Range checking can be
+ disabled by defining the macro BOOST_DISABLE_ASSERTS before
+ including multi_array.hpp. A bug in
+ multi_array::resize() related to storage orders was fixed.
+ - Multi-index Containers
+ Library:
+
+
- Optional
+ Library:
+
+ boost::none_t and boost::none now added to Optional's
+ documentation
+ - Relational operators now directly support arguments of type
+
'T' and 'none_t'
+ - operator->() now also works with reference types.
+
- Helper functions
make_optional(val), make_optional(cond,val)
+ and get_optional_value_or(opt,alternative_value) added.
+ - Constructor taking a boolean condition (as well as a value) added.
+
+
- Member function
get_value_or(alternative_value)
+ added.
+ - Incompatbility bug with mpl::apply<> fixed.
+
- Converting assignment bug with uninitialized lvalues fixed.
+
+ - Parameter
+ Library:
+
+ - Every ArgumentPack is now a valid MPL Forward
+ Sequence.
+
- Support for unnamed arguments (those whose keyword is deduced from
+ their types) is added.
+
- Support for named and unnamed template arguments is added.
+
- New overload generation macros solve the forwarding
+ problem directly.
+
- See also the Python library changes, below.
+ - Pointer
+ Container Library:
+
+ - Support for serialization via Boost.Serialization.
+
- Exceptions can be disabled by defining the macro
+ BOOST_PTR_CONTAINER_NO_EXCEPTIONS before including any header. This
+ macro is defined by default if BOOST_NO_EXCEPTIONS is defined.
+
- Additional
std::auto_ptr<T> overloads added
+ s.t. one can also pass std::auto_ptr<T> instead of
+ only T* arguments to member functions.
+ transfer() now has weaker requirements s.t. one can
+ transfer objects from ptr_container<Derived> to
+ ptr_container<Base>,
+ - Python
+ Library:
+
+ - Boost.Python now automatically appends C++ signatures to
+ docstrings. The new
docstring_options.hpp
+ header is available to control the content of docstrings.
+ stl_input_iterator,
+ for turning a Python iterable object into an STL input iterator, from
+ Eric Niebler.
+ - Support for
void* conversions is added.
+ - Integrated support for wrapping C++ functions built with the
+ parameter library; keyword names are automatically known to
+ docsstrings.
+
- Enhancements to the API for better embedding support
+ (
boost::python::import(),
+ boost::python::exec(), and
+ boost::python::exec_file()).
+ - Signals
+ Library: More improvements to signal invocation performance
+ from Robert Zeh.
+
- Smart
+ Pointers Library:
+
+
- String Algorithm
+ Library:
+
+ lexicographical_compare
+ join
+ - New comparison predicates
is_less,
+ is_not_greater.
+ - Negative indexes support (like Perl) in various algorihtms
+ (
*_head/tail, *_nth).
+ - Wave
+ Library:
+
+ - Wave now correctly recognizes pp-number tokens as mandated by the
+ C++ Standard, which are converted to C++ tokens right before they are
+ returned from the library.
+
- Several new preprocessing hooks have been added. For a complete
+ description please refer to the related documentation page: The Context
+ Policy.
+
- Shared library (dll) support has been added for the generated Wave
+ libraries.
+
- The overall error handling has been improved. It is now possible
+ to recover and continue after an error or a warning was issued.
+
- Support for optional comment and/or full whitespace preservation
+ in the generated output stream has been added.
+
- The Wave library now performs automatic include guard detection to
+ avoid accessing header files more than once, if appropriate.
+
- Full interactive mode has been added to the Wave tool. Now the
+ Wave tool can be used just like Python or Perl for instance to
+ interactively try out your BOOST_PP macros. Additionally it is now
+ possible to load and save the current state of an interactive session
+ (macro tables et.al.).
+
- The overall performance has been improved by upto 40-60%,
+ depending on the concrete files to process.
+
- Support for new pragmas has been added allowing to control certain
+ library features from inside the preprocessed sources (partial output
+ redirection, control of generated whitespace and #line directives).
+
- Optional support for #pragma message "..." has been added.
+
- This version also includes a number of bug fixes and usage
+ improvements. For a complete list of changes, see the libraries change log.
+ Supported Compilers
+ Boost is tested on a wide range of compilers and platforms. Since Boost
+ libraries rely on modern C++ features not available in all compilers, not
+ all Boost libraries will work with every compiler. The following compilers
+ and platforms have been extensively tested with Boost, although many other
+ compilers and platforms will work as well. For more information, see the
+ regression test
+ results.
+
+ - Apple GCC 4.0.1 on Mac OS
+ X.
+
- Borland
+ C++ 5.8.2 on Windows.
+
- GNU C++
+
+ - 3.2.x., 3.3.x, 3.4.x, 4.0.x, 4.1.x on Linux
+
- 4.1.x on Solaris
+
- 3.4.x on Windows
+ - HP aC++ A.06.14.
+
- Intel
+ C++ 9.1 on Windows, 9.0 on Linux.
+
- Metrowerks CodeWarrior 9.4
+ on Windows.
+
- Microsoft Visual
+ C++ 6.0 (sp5, with and without STLport), 7.0, 7.1, 8.0. Note: Boost
+ does not support the non-standard "Safe" C++ Library shipping with
+ Visual C++ 8.0, which may result in many spurious warnings from Boost
+ headers and other standards-conforming C++ code. To suppress these
+ warnings, define the macro
_SCL_SECURE_NO_DEPRECATE.
+ - Sun
+ Studio 11 on Solaris.
