Indent after first line [message #1732738]

I am using Xtext 2.9 formatter2 API.

I am trying to figure out how to cause the formatter to produce indentation like in the following example:

relation X
   from Y
   to Z

In other words, I would like to insert new lines before "from" and "to" and indent them.

My current code looks like this:

	def dispatch format(Relationship relationship, extension IFormattableDocument document) {
		relationship.prepend[newLines = 2]
		relationship.regionFor.keyword("from").prepend[newLine]
		relationship.regionFor.keyword("to").prepend[newLine]
	}

which adds the new lines but not the indentation. How do I modify it, to add the indentation? Thanks in advance.

I just realized that my example above did not have indentation, but I meant to have an indentation right before "from" and right before "to".

How does your grammar look like

Here is some of my grammer rules:

Entity:
	(isAbstract?='abstract')? 'entity' name=ID
;

Relationship:
	((isSymmetric?='symmetric')? &
	(isAsymmetric?='asymmetric')?)
	'relationship' name=ID
	'from' source=[Entity]
	'to' target=[Entity]
;

set(relationship.regionFor.keyword("from").previousHiddenRegion, relationship.regionFor.feature(MyDslPackage.Literals.RELATIONSHIP_SOURCE).nextHiddenRegion)[indent]
set(relationship.regionFor.keyword("to").previousHiddenRegion, relationship.regionFor.feature(MyDslPackage.Literals.RELATIONSHIP_TARGET).nextHiddenRegion)[indent]

Hi Maged,

where you created the method to indent the lines? I saw your 'def dispatch format' method, but I don't know where to do the same here.

Thanks

If you add a

formatter = { generateStub = true} to the workflow you will get a stub class generated. Add you methods there

Example :
typesDecl.interior[indent] // Indente after TypeDecl and until the end of the region
