yasmine

yasmine is a C++ state machine framework developed by Seadex. The latest stable version is 1.5.3.

The very first beta version (0.1.0) was released on June 20, 2016. Originally only supporting C++11 support for C++03 was added with Beta 6 (0.6.0). Version 1.0.0, the first stable version, was released January 20, 2017. The complete version history is available for you, too.

yasmine is not just yet another state machine framework! It is an easy to use high level UML state machine abstraction that nicely integrates with modern object oriented C++ code.

She is also highly portable. yasmine is in active use under Linux and Windows. Hardware platforms she's running on include x86, ARM, and Blackfin. Builds are actively tested for MSVC, gcc, and Clang.

We created her, because we often use state machines in the projects we work on. And using existing solutions was not quite satisfying. Some didn't feel like they integrated into modern C++ code nicely (coded in C, switch case based, ...), others required the overhead of big frameworks. Then in some cases pulling in closed source libraries is a problem, because risk assessment is tricky (medical applications). And then there are solutions that seem quite nice, but never matured, are not maintained or poorly maintained, or poorly documented.

yasmine adheres as closely as possible to the UML state machine semantics. Key features are hierarchical states, orthogonal regions, and the support of run-to-completion semantics. For detailed information read more about her features in the documentation. We are creating a whole ecosystem around the core library, that makes creating and maintaining state machine easier and more comfortable.

The core library libyasmine itself, the model library yasmine_model, and the command line state machine generator ygen are free for commercial and non-commercial use (see License for details). ygen_ui, the generator with graphical user interface, and the Enterprise Architect addin are commercial products which require you to buy a license for them. Currently beta versions of ygen_ui and of the EA addin can be obtained from the downloads section. The beta versions are free for evaluation and test purposes.

Also Commercial support by Seadex can be obtained (development, training, technical support).

You can also visit our forums at http://seadex.de/forums and post there if you have a suggestion, a question or want to give us any other kind of feedback. Also if you find yasmine useful, we would be glad if you would show your appreciation!

Credit goes to Jonathon Reach for his effort of reading the entire documentation and for supplying us with lots of suggestions. This helped to improve these pages a lot. Thanks!

Advantages of using yasmine

  • She provides a complete implementation of UML state machine semantics (which extend FSM (Finite State Machine) semantics significantly).

  • yasmine is a modern C++ implementation using C++11 (C++03 support is available, too).

  • Because it's C++ (and not C) the code integrates nicely into OO code.

  • She's well documented (If you think something is missing or unclear), please let us know.

  • Because she is open source you can check her implementation out. Also this guarantees long term usability and availability.

  • You can get support from Seadex. We appreciate your feedback and are open for feature requests and glad about bug reports.

  • The library enables you to create state machines at runtime.

  • yasmine will keep improving. The ecosystem around yasmine will grow, we will add even more tests, and also add to the documentation.

  • No additional dependencies are introduced in an C++11 environment. yasmine only uses the C++11 standard library - nothing else.
    If you need support for C++03, then Boost is required to bridge some of the gaps the lacking C++11 support causes.

What yasmine is not

She's not a minimum foot print library that prioritizes on running on every system no matter how few resources are available. yasmine is not resource hungry, but she cannot (and does not want to) compete with switch-case-based bare-metal no-abstraction libraries.
