New construction in the Build Language

The test module configuration in the build language has been extended. Now it is possible to specify additional IntelliJ IDEA plugins which must be loaded when MPS ant tests are executed.

The plugins required for MPS Ant test execution used to be calculated automatically. However, there are scenarios when the test needs a particular plugin in its environment, which the MPS build language engine could not deduce from the modules containing the tests.

Now you can ensure that the plugin you need is present during the MPS Ant test execution.

Reusable cell action maps

Cell action map items from an existing action map can be reused in a new action map via imports. action-map-imports

 

Generator language

The $INCLUDE$ macro has been deprecated and there’s a migration to replace its instances with $CALL$. The former did not support templates with arguments, and there’s no reason to keep two mechanisms to invoke a template.

The $WEAVE$ macro and weaving rules can now invoke templates with arguments.

When an interpreted template weaves an external template from a ‘compiled’ generator, it is no longer interpreted, but the compiled template code is executed.

‘Compiled’ templates may weave interpreted templates now.

The collection of queries from a template model, also known as QueriesGenerated, no longer uses Java reflections.

 

New icon for behavior methods overridden or implemented

The behavior methods have been equipped with a new icon. Click on it to display the list of all the methods overridden and implemented.

The latest Early Access Program for MPS 2018.2 is here.

 

Try the MPS 2018.2 EAP5 here. In this new version, you can expect to see enhanced generation plans. There’s a new statement in generation plans: fork with <another generation plan> to branch the transformation sequence at a given point.

gpfork1

Referenced plan receives a model in the state it was at the fork step and proceeds as a regular transformation. In the example above, we transform input model with crossmodel.entity generator first, then record a state and go on with crossmodel.property#553 generator to eventually get output model #1. Then, crossmodel.property#g2 generator transforms the recorded model to get output model #2. Note that ‘then’ here is not a contract – there’s no promise that branches get processed in any specific order, except that the ‘primary’ branch, the one from the initial plan, gives the ‘first and only’ output model available through old API (GenerationStatus#getOutputModel) for compatibility/migration purposes.

At the end of the day, a transformation of a model may end up with multiple output models. All transient output models have the same name but different stereotype, and share the same output location (determined by input model), which is why further artifacts (like textgen) end up together. 

We love receiving your reports in our issue tracker. Keep them coming!

Have a nice day!
