As some of you already know, I've been working on producing a Boost implementation of the Technical Report on C++ Library Extensions, the first full version is now available from: http://boost-sandbox.sourceforge.net/vault/index.php?&direction=0&order=&directory=tr1 The documentation can also be viewed online at: http://freespace.virgin.net/boost.regex/tr1/doc/html/tr1.html For those new to the TR, the following are supported in this release: Reference Wrappers Smart Pointers Class template result_of. Function template mem_fn. Function Object Binders. Polymorphic function wrappers. Type Traits. Random Number Generators and Distributions. Tuples. Tuple Interface to std::pair. Fixed Size Array. Hash Function Objects. Regular Expressions. Complex Number Algorithm Overloads. Complex Number Additional Algorithms. The following are not yet supported, but will be as soon as hash-tables make it into Boost: Unordered Associative Set (Hash Table). Unordered Associative Map (Hash Table). The following do not currently have Boost-licence compatible implementations and are not supported: Mathematical Special Functions. C99 Math Functions. Finally, note that I may split the complex number stuff out into a separate submission (I'll post another message about this). As ever, comments are most welcome. John.
