The Boost C++ Libraries are a collection of peer-reviewed, open source libraries that extend the functionality of C++.

Contents

Overview

Most of the Boost libraries are licensed under the Boost Software License, designed to allow Boost to be used with both free and proprietary software projects. Many of Boost's founders are on the C++ standard committee and several Boost libraries have been accepted for incorporation into both the Technical Report 1 and C++0x.[1]

The libraries are aimed at a wide range of C++ users and application domains. They range from general-purpose libraries like the smart_ptr library, to operating system abstractions like Boost FileSystem, to libraries primarily aimed at other library developers and advanced C++ users, like the metaprogramming template (MPL) and DSL creation (Proto).

In order to ensure efficiency and flexibility, Boost makes extensive use of templates. Boost has been a source of extensive work and research into generic programming and metaprogramming in C++.

The current Boost release contains over 80 individual libraries, including libraries for linear algebra, pseudorandom number generation, multithreading, image processing, regular expressions, unit testing, and many others. The majority of Boost libraries are header based, consisting of inline functions and templates, and as such do not need to be built in advance of their usage.

Associated people

Original founders of Boost still active in the community include Beman Dawes and David Abrahams. Author of several books on C++, Nicolai Josuttis contributed the Boost array library in 2001. Around 3,000 people are subscribed to Boost mail-list and dozens of them are very active (as of 2007).
