How to prevent newline while formatting with Xtend - xtext

Question

My Xtend formatter class extends AbstractFormatter2 and I would like it to format this code:
Board my_board {
Pin {
Name = my_name;
Comment = "my_comment";
Id= "my_id";
}
}
to this one:
Board my_board {
Pin {
Name = my_name; Comment = "my_comment"; Id= "my_id";
}
}
I have written the following Xtend code in a format function, but the text to be formatted remains the same.
val open = pin.regionFor.keyword('Name')
val close = pin.regionFor.keyword('Id')
interior(open, close)[newLines = 0]
What is the proper way to achieve this, please?

Answer 1

you can try
var open = pin.regionFor.keyword('Name')
val close = pin.regionFor.keyword("Id")
while (open !== close) {
open.append[
oneSpace
]
open = open.nextSemanticRegion
}
or
var open = pin.regionFor.keyword('Name')
val close = pin.regionFor.assignment(pinAccess.myIdAssignment_12)
while (open !== close) {
open.append[
oneSpace
]
open = open.nextSemanticRegion
}
