58 58  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. Write a formatter configuration that fits well to your syntax by editing the generated file {{code language="none"}}TuringFormatter{{/code}} in the {{code language="none"}}formatting{{/code}} subpackage. Learn how this is done by reading the Xtext reference documentation → Runtime Concepts → Formatting.

62 +The generated code includes some automatic validation of models with respect to syntactic issues. If the token sequence in a text file does not conform to the grammar, error markers are shown at appropriate points in the text. However, this should be augmented by semantic validation by checking high-level properties of the model. Implement such a semantic validation by editing the generated file {{code language="none"}}TuringJavaValidator{{/code}} in the {{code language="none"}}validation{{/code}} subpackage. Learn how this is done by reading the Xtext reference documentation → Runtime Concepts → Validation → Custom Validation. You should implement at least the following checks:

64 +* Is there exactly one initial state?
65 +* Are all states reachable through transitions starting from the initial state?
