As a result of our Sprint 2021.04, there are now two deliveries available for download: HCL RTist 11.0 2021.04 and experimental version 11.1 2021.04.

Although the experimental version is not yet recommended for production use, we would greatly value any feedback you may have on it. Feel free to reach out to the development team.

For now, let’s take a look at what’s new:

Single-command Scripted Installation

Installation of HCL RTist has never been easier! Just download the script from this page in Utilities section and after a simple configuration, given a product zip file it will automatically download corresponding Eclipse version and depending on RTist version being installed will perform all necessary configuration and installation steps to get you going in minutes.

Visualization of Event Routing

Complex UML RT models often have many levels of nested capsules, making it difficult to analyze how events are travelling through these structures. In Sprint 2021.04 HCL RTist provides experimental Event Routing Visualization feature, which generates a read-only view of all possible communication paths and relevant parts with respect to a certain port. Despite the new view cannot be used to change the model, you can pan and zoom the diagram, filter to only show paths for In or Out events and switch root capsule context with “Go Inside” and “Go Outside” commands. Please keep in mind that to try this feature you should first activate it in Experimental Features Preferences page.



Simpler Qualified Names

In many places in RTist like e.g. Properties view you could see fully qualified names of UML elements. Qualified Name of an element includes names of all owning model elements up to the model’s root separated by ::. However Capsule Development viewpoint simplifies model representation by hiding some types of elements in Project Explorer view, for example Regions in statemachines. Starting from Sprint 2021.04 fully qualified names in Find Named Element dialog, Code View hints, and Properties view are viewpoint aware. In case of Capsule Development viewpoint this results in shorter, easier to understand qualified names especially for nested states.


C++ 11 Initializers Support Improvements

C++ 11 provides new ways to initialize data members of a class called brace and equal initializations. This is in addition to previously existed constructor and assignment initializations. In RTist, you can also configure which kind to use by means of C++ General section of the Properties view for the corresponding Attribute. In this Sprint initializers support was streamlined in the following way. If Initializer Kind is brace or equal it will normally be generated in the header file, otherwise in .cpp file. Taking this into account, you should be careful in using brace or equal initializers for global variables to avoid duplicate declarations in every .cpp file that includes the corresponding header. However if constexpr keyword is used, the initialization will be always generated in the header file. Enjoy the C++ 11 features with errorless builds.

Storing Code in Model Files Using CDATA
RTist models are stored in XML files (.emx and .efx). If you have ever opened such a file in a text editor you have probably noticed that code snippets stored in the model can be quite difficult to read due to the encoding of certain characters that is mandated by XML. Here is an example:     Some code snippets are stored as attributes in XML and they can look even worse, since newlines also will be encoded so that the whole code snippet appears on a single line:     Starting with RTist 11.0 2020.33 it's now possible to set a preference so that code snippets will be saved in CDATA sections in the XML file. Thereby the code does not need to be escaped which greatly improves its readability. The preference is called Use CDATA when saving model files and is located on the Modeling preference page. In addition to code snippets, it also affects how documentation texts are stored.     After setting this preference, the code snippets in the examples above will look like this:       Note that older versions of RTist can still read model files that use CDATA. In that sense this feature is backwards compatible. Note, however, that if you edit and save the model in such an old tool version the code snippets will once again be stored without usage of CDATA.  If you decide to start using CDATA in your model files it can be a bit tedious to manually re-save all files in the workspace to use the new format. To simplify you can run a model fixup which will automatically convert all your model files to use CDATA.     Watch this video for more information.
