You might want to check out my work at http://sourceforge.net/projects/easyasap/ (ex: easyasap_s5.3.8.3.tar.gz) - The fsm code tree is the general C++ code - The EVM code tree uses this to implement statesystems from a database (ex: postgres, sqlserver), supporting actions like dynamic-loading, soap invocation, etc. David Abrahams wrote:

Subject: State machine framework with dynamic configurability From: "Dave" <pplppp@gmail.com> Date: 23 Jun 2005 19:12:54 -0400 To: (Usenet)

Hi all, I'm working on a project to improving a legacy software on Unix which has a flat state machine with hundreds of states in it. I'm looking for a state machine framework that supports nested states, guards, entry, exit and preferrably other state machine features such as concurrent state transitions, orthorgonal states, shallow/deep histories. Another requirement is that the state machine framework should be dynamically configurable, say in my main program I have 3 states, and i can build a shared object which defines a state machine as a sub-state machine for one of the states in the main program. All these should be achieved without recompiling the main program.

I looked into the boost statechart library and dug up the thread that Andreas Huber started when the idea to create boost statechart was first hatched. The only problem is that the library wasn't designed with dynamic configurability in mind, so it doesn't suit my needs.

I also looked into the quantum platform, etc framework, but I have trouble finding documentation (perhaps I need to buy the book?)

I've also tried a statechart modelling tool called SmartState and used it to generate a state machine but the state machine features supported are limited and I have some reservations about the design of the state machine framework that the tool generates

So.. my question is: is there any other state machine framework that is dynamically configurable and support the most of the state machine features mentioned above?

any help is welcome, thanks in advance

newbie
