How to format datatype rules with Formatter2 [message #1697370]

I have already tried Formatter2 of XText 2.9. It works well. But i could not find any way to format the datatype rules.

e.g. following grammar

Expression:
      value=Real
;

Real:
      INT '.' INT
;

I hope to format the rule 'Real' so that there are no white spaces existing before and after '.'

The method "regionFor(EObject).*" works only for EObject. The datatype rule 'Real' generates only "String" insteadof "EObject".

How can i format the datatype rules? Is there any other formatting method for datatype rules?

regionForFeature /region.forFeature on the parent should do the trick

I could not find the method "regionForFeature".
Do you mean "regionFor(expression) .feature(Literals.Expression_Value)"?
I use just this method. It can only append/prepend white spaces around "Real" instead of around '.' within the "Real".

You need to define a ValueConverter for Real DataType in your IValueConverterService class. Here you can override toValue where you programmatically remove the spaces. This is applied on formatting.
