Simple yet powerful C++ finite state machine library.
- State is represented by a pointer
- Concise syntax understandable for average C++11 programmer
- Entry/exit actions
- Allows both per-FSM and per-state variables
- Transitions and guards expressed as C++ code (if/else, function calls, ...)
- FSM can react to custom events represented by arbitrary types
- Events can contain an arbitrary payload that can be used in the handling code
- No memory allocation during state changes (like in Boost Statechart)
- No need to increase limits of other libraries (like
BOOST_MPL_LIMIT_VECTOR_SIZEneeded by Boost MSM) - No "advanced" template magic. Light template usage (understandable to me) is allowed :)
- Allows multiple instances of the same state machine (as opposed to tinyfsm)
- Compile-time enforcement of passing additional data when transitioning to selected states (e.g., error code must be specified when entering an error state).
- Supports nested state machines
MSFSM is a header-only library. Just copy msfsm.hpp to your project
and include it.
