Example of DSL grammar:

grammar hellodsl.HelloDsl with org.eclipse.xtext.common.Terminals

generate helloDsl "http://www.HelloDsl.hellodsl"

Model:
	statements+=Statement*;

Statement:
	Join|Leave|Greeting;

Join:
	'Join' name=ID ';';

Leave:
	'Leave' name=ID ';';

Greeting:
	'Hello' name=ID ';';

Example of DSL script:

Join Alice;
Join Bob;
Join Mike;
Leave Alice;
Hello

How to add in autocomplete (Ctrl-SPACE) after "Hello" only names, defined above in "Join" statement and except names, defined in "Leave" statement? For this example must be 2 variants:

Hello <cursor here>
1) Bob
2) Mike

Hi do you know the concept of cross references and scoping? that is perfect for this usecase.
alternatively have a look at the proposal providers complete Greeting_name method. you can use the context parameter to access the model and traverse it
