Hi, I would like to ask for a formal review of the Boost.FSM library proposed here not long ago. I've uploaded the implementation, test and documentation into Boost.Vault, it is accessible with this link: http://tinyurl.com/yjozfn There were several changes in the library since the proposal: - Integral constants tagged events support added - Transitions maps support improved. Each transition may now decide in run-time to which state to transit. The transition map itself may be broken into several pieces - the common part and state-specific parts. - Added an implementation of thread-locking state machine. It is quite equivalent to the "state_machine" class but adds a tiny synchronization layer between environment and the machine. - The library has been split into several headers and put into its own directory. - The documentation have been improved. -- Best regards, Andrey mailto:andysem@mail.ru PS: Happy New Year everyone!
