Hi, i'm new at Xtext and grammar writing stuff and i need to write a multiline comment. The Xtext rule stands for:

 ML_COMMENT: '/*' -> '*/';

But my ML_COMMENT must be:

ML_COMMENT: '(*' -> '*)';

The rule seems to be right. The expected behavior is when the first '(*' appears, all the next lines must change to comment color.
The actual behavior is when type '(' the editor automatically completes the parentesis, and if i type '(*' the lines doesn't show in comment color, only if i close the token.

Just like this:

(* this shows work perfectly *)

(* this not works          //must already be in commentary

Thanks for any tips.

Hi,

this is the very same how /* */ multi line comments behave. i dont think it is easy to detect this in semantic highlighting.
what you could do is to fix the AutoEditStrategyProvider. configureMultilineComments
