hi,

I am working with this grammar (snippet):


Entity returns modulob::Entity:
	(annotations+=Annotation)*
	(isAbstract?='abstract')? 'entity' name=ID (':' super=[modulob::Entity])?'{'
		(features+=Feature)*
	'}'
;

Annotation returns modulob::Annotation:
	'@' option=ConfigOption (':' value=ConfigValue)?
;

Feature returns modulob::Feature:
	(isIndexed?='indexed')?
	(isContainment?='-[')?
	type=TypeRef name=ID ('=' defaultValue=ValueObject)? 
	('<->' inverse=[modulob::Feature | QualifiedName])?
	(';')?
;

With these formatting rules:

protected void configureFormatting(FormattingConfig c) {
  c.setLinewrap(2).after(((DataDslGrammarAccess)getGrammarAccess()).getEntityModelAccess().getVersionSTRINGTerminalRuleCall_3_0());
  c.setLinewrap().after(((DataDslGrammarAccess)getGrammarAccess()).getEntityRule());
  c.setLinewrap().after(((DataDslGrammarAccess)getGrammarAccess()).getEntityAccess().getAnnotationsAssignment_0());
  c.setNoSpace().after(((DataDslGrammarAccess)getGrammarAccess()).getAnnotationAccess().getCommercialAtKeyword_0());
  c.setNoSpace().after(((DataDslGrammarAccess)getGrammarAccess()).getAnnotationAccess().getColonKeyword_2_0());
  c.setNoSpace().after(((DataDslGrammarAccess)getGrammarAccess()).getAnnotationAccess().getOptionAssignment_1());
  c.setNoSpace().after(((DataDslGrammarAccess)getGrammarAccess()).getAnnotationAccess().getValueAssignment_2_1());
  c.setLinewrap().after(((DataDslGrammarAccess)getGrammarAccess()).getEntityAccess().getLeftCurlyBracketKeyword_5());
  c.setLinewrap().after(((DataDslGrammarAccess)getGrammarAccess()).getFeatureAccess().getSemicolonKeyword_6());
}

an entity looks like this:

entity Entry {
String uuid ;
indexed Timestamp timestamp ;
String username ;
String message ;
}

I want to achieve that each feature is indented like this:

entity Entry {
   String uuid ;
   indexed Timestamp timestamp ;
   String username ;
   String message ;
}

I tried to use

c.setWrappedLineIndentation(3);

but with no success. How can one specify indentations using FormattingConfig?

regards,

steven

Hi,

what about something like

c.setIndentationIncrement().after(((MyDslGrammarAccess)getGrammarAccess()).getEntityAccess().getLeftCurlyBracketKeyword_4());
c.setIndentationDecrement().before(((MyDslGrammarAccess)getGrammarAccess()).getEntityAccess().getRightCurlyBracketKeyword_6());

that did it. I just did not understand what 'setIndentationIncrement' means.

thanks!
