Reminder - We have just past the half way point for the formal review of dynamic bitset. So far we have: 1 formal yes vote 1 formal no vote Discussion regarding iterators for dynamic bitset and comparison to vector<bool>. Some minor corrections and updates. I would like to see more formal reviews (including a yes or no vote) before the review period ends on the 17th. Thanks, Mat #####

The formal review of Dynamic Bitset by Chuck Alison and Jeremy Siek will commence today Saturday June 8th and run through Monday, June 17th.

The library is currently available at <http://groups.yahoo.com/group/boost/files/dyn_bitset.tar.gz>

Below is an excerpt from the library's documentation:

The dyn_bitset class represents a set of bits. It provides accesses to the value of individual bits via an operator[] and provides all of the bitwise operators that one can apply to builtin integers, such as operator&& and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dyn_bitset.

Each bit represents either the Boolean value true (set) or false (reset). To toggle a bit is to change the value to true if it is false and to false if it is true. Each bit has a non-negative position pos. The position pos == 0 corresponds to the least significant bit and pos == size() - 1 is the most significant bit. When converting an instance of dyn_bitset to or from an unsigned long, the bit position pos corresponds to the bit value 1 << pos.

The dyn_bitset class is nearly identical to the std::bitset class. The difference is that the size of the dyn_bitset (the number of bits) is specified at run-time during the construction of a dyn_bitset object, whereas the size of a std::bitset is specified at compile-time through an integer template parameter.

For information about submitting a Formal Review, see http://www.boost.org/more/formal_review_process.htm

Please try out the library and comment during the review period. Be sure to say whether or not you think the library should be accepted by Boost.

Compiler notes: This library has been tested using the following compiler platforms:

Gcc 2.95 and 3.01 Kai C++ Metrowerks Codewarrior 8 (beta, Mac) Visual C++ 7.0 Comeau

The library presently requires template friend support and is known not to compile with CodeWarrior 7.2 or Visual C++ 6.0.

The library has not been tested with Borland.

The Formal Review manager is Mat Marcus.
