Textual State Machines

State machines are usually created in Model RealTime by means of graphical state chart diagrams. However, it's also possible to define them textually, using an Model RealTime specific language called "Statemachine RT" (or SRT for short). The SRT language contains all necessary state machine constructs, including a way to embedd C++ code snippets. Creating textual state machines with SRT has some advantages over using graphical diagrams:

• Certain editing tasks are faster to perform in a textual editor compared to a graphical diagram. Examples include copy/paste, refactoring etc.
• With SRT all code snippets of a capsule can be viewed and edited in a single text editor. For example, this makes searching in these code snippets easier. It also reduces the number of open editors in Model RealTime.
• Commonly used state machine constructs can be defined as textual templates, which further can speed up the creation of new state machines.
• Merging changes in state machines is sometimes easier using a textual notation.

The support for textual state machines is an optional and experimental feature that is not installed by default. To install it, mark the item Textual State Machines that is located in the Model RealTime Extra Functionality category when installing Model RealTime.
