YAKINDU Statechart Tools 4.0.2 (Nov 06, 2020)

This is mainly a bugfix release, containing several fixes for our code generators and the YET infrastructure, but also some usability improvements.

Code Generation​

In this release we added new feature for the C and C++ code generators: It is now possible to generate a software timer service implementation by using the 'timerService' parameter in the generator model, like in the example below:

Example:

feature GeneralFeatures {
    timerService = true
}

Furthermore, we fixed several issues, among others:

  • We fixed an issue in the C code generator where the generated check methods for choice transitions incorrectly used a const qualifier.
  • We fixed an issue the C code generator when type aliases were defined in a C/C++ domain statechart.
  • We fixed the C code generator for statechart using certain combinations of event buffering and time events.
  • We changed the names of the event and feature enumerators to be more consistent with the other API methods (no 'Iface' in the name)
  • We fixed an issue in the C code generator when generic tracing is enabled.
  • For multi state machine scenarios, we fixed an issue in the C++ code generator when the 'isStateActive' method is used.
  • For multi state machine scenarios, we fixed all code generators to properly reference sub machines that use a namespace.
  • We removed the obsolete parameters 'apiTargetFolder' and 'apiTargetPackage' from the Java and Python generator models.

YET Infrastructure​

For this release, we also spent some effort in further improving the CREATE Execution Trace (CET) infrastructure:

  • We improved the YET C code generator to make the generated code compilable with pedantic checks,
  • We fixed an issue in the YET C code generator and debugger when declarations in named statechart interfaces were used.
  • We fixed several minor issues in the YET debugger

Editor Usability and Other Fixes​

  • We fixed several smaller usability issues to make statechart modeling more convenient.
  • Selecting a region is now more intuitive again: Single click just selects the region; click & move spans a multi-selection rectangle.
  • We fixed an issue causing an incorrect region order when moving a region into an orthogonal state.
  • For C/C++ domain statecharts, it is now possible to access external members, that are in the same namespace as the statechart, without the namespace qualifier.
  • Fixed an issue with the quick-fix to change the statechart domain in the generator model.
  • New SCTUnit files now proper reference the selected statechart when it declares a namespace.
