We just finished migrating the language visualization plugin to MPS 2017.3.
This extension can visualize the structure of a language graphically, in order to give insight for new people learning a language, and to save effort in creating diagrams of a language.
You will need PlantUML to make a picture of the language visualization. The visualization will be saved as mps-metamodel.txt in your home directory. Easiest is just to start PlantUML, let it point to mps-metamodel.txt, and after every visualization command, you will see the updated picture in PlantUML. Please see https://github.com/DSLFoundry/mps-langvis/blob/master/README.md for more information.
Using the extension can be done in two ways (we use the Entities language (https://github.com/DSLFoundry/mps-entities-tutorial) as an example):
- Right-click the structure of a language and choose → Visualize Language Structure (you might need to scroll down a bit if you have mbeddr plugins installed, as there are quite some items in the pop-up menu after you right-click):
which will lead to a picture like this, when we open it in PlantUML:
- Right-click a concept in a language’s structure and choose → Visualize Concept Context:
which will lead to a picture like this:
