Hi Christian,

I have # comment in my dsl.

If it starts with # the remaining line should be in green. But if I using ## at begin it is not behaving like a comment. And also line starts with single # also not working properly. Can you please tell me whats wrong with terminal riule?

as i am not the only guy answering questions here you do not need to adress me personally.

to your question:

you know xtext is not "line based"

so

firstpart ## secondpart

and

firstpart 
## secondpart

are the same from a parser point of view?

so is your semantics linebased?

p.s.

did you try something like

grammar org.xtext.example.mydsl6.MyDsl with org.eclipse.xtext.common.Terminals
 hidden(WS, ML_COMMENT, SL_COMMENT, HASH_COMMENT)

generate myDsl "http://www.xtext.org/example/mydsl6/MyDsl"

Model:
	(greetings+=Greeting)*;
	
Greeting:
	name1=ID '##' name2=ID;
	
terminal HASH_COMMENT : ('#'('\r'? '\n')?) | ('#' !('#'|'\n'|'\r')+ ('\r'? '\n')?) | (('#''#''#') !('\n'|'\r')* ('\r'? '\n')?);
