This is a beta version of Boost. The current version is 1.90.0.
C++11 implementations of standard components added in later C++ standards.
The Boost Exception library supports transporting of arbitrary data in exception objects, and transporting of exceptions between threads.
In C++, writing a loop that iterates over a sequence is tedious. We can either use iterators, which requires a considerable amount of boiler-plate, or we can use the std::for_each() algorithm and move our loop body into a predicate, which requires no less boiler-plate and forces us to move our logic far from where it will be used. In contrast, some other languages, like Perl, provide a dedicated "foreach" construct that automates this process. BOOST_FOREACH is just such a construct for C++. It iterates over sequences for us, freeing us from having to deal directly with iterators or write predicates.
Open-methods are virtual functions that exist outside of classes, as free-standing functions. They make it possible to add polymorphic behavior to existing classes, without modifying them. This implementation supports single and multiple dispatch.
A deterministic failure handling library partially simulating lightweight exceptions.
Boost.Parameter Library - Write functions that accept arguments by name.
A common infrastructure for throwing exceptions from Boost libraries.
