Test the new grammar by re-generating the code (after the first time, the GenerateTuring workflow should be available in the run configurations menu) and starting a test instance of Eclipse.

Xtext supports automatic formatting, which is available in the text editor with right-click → Format or ctrl+shift+F. However, the formatter must be configured in order to generate good results.
