Xtext VS Code example

This is a simple example showing the Xtext integration for VS Code based on the Microsoft Language Server Protocol.

The base is following simple grammar

Model:
    greetings+=Greeting*;
    
Greeting:
    'Hello' name=ID ('from' from=[Greeting])? '!';

A typical example model would look like (Open a new folder in VSCode and create the files)

a.mydsl

Hello Xtext!
Hello VSCode from Xtext!
Hello ThisFile from Other!
Hello you!

b.mydsl

/* this is a definition in another file */
Hello Other!

The Xtext integration supports typical Xtext and Language Server features like

• Syntax Highlighting
• Validation
• Goto Definition / Find References
• Hover
• Formatting
• Mark Occurrences
• Open Symbol
