Hi ,

I get an exception at the following part of code.


def private ContentAssistContext[] getContexts(XtextResource resource, String text, ITextRegion selection,
int caretOffset) {
if (caretOffset > text.length)
return #[]
val contextFactory = contextFactoryProvider.get() => [pool = Executors.newCachedThreadPool]
contextFactory.create(text, selection, caretOffset, resource)
}


This happens when the input is

"plot abc by tim by adviser by"


This does not happen when the input

"plot abc by tim by adviser"



my grammar :

Model:
	greetings=Query;

Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) ((groupBy=GroupList)? &(condition=Condtition)? &(range=Transition)?) ;


QTypekeyWord:
	qKeyword='plot'
;

Aggregation:
	agg=('average'|'number of'|'total')
;

Condtition:
	con+='for' dimVal=DimensionValue 'as' dim=Dimension ('and' dimValue=DimensionValue 'as' dimen=Dimension)*
;

MeasureList : names+=Measure ("and" names+=Measure)*;

Measure:ID+;


Dimension:
	dimensions+=ID+
;

DimensionValue:
	value=ID+
;

GroupList:
	(=> "by" (timeGroups+=TimeGroup|dimensionGroups+=Dimension))+
;
Transition:

	'from' dateStart=Date 'to' dateEnd=Date
;

TimeGroup:

	timeGroup=('day'|'week'|'month'|'quarter'|'year')
;
Date:
	d=Day m=Month y=Year ;


Day : INT ;
Month : 'Jan'|'Feb'|'Mar'|'Apr' ;
Year : INT ;

hi can you please file a bug?

does the following work as workaround or does it destroy something?


Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) ((groupBy+=Group)* &(condition=Condtition)? &(range=Transition)?) ;

Group:
	 
	
	"by" timeGroups+=TimeGroup|
	
	"by" dimensionGroups+=Dimension
		
	
;

Ok Thank You. Saved my time. Smile

I have a question on this grammar.
I wish to change the definition of the grammar to support just two cases

by dimension by time .Here when dimension is there then only time should come
by time .only by time can also be allowed.

So in summary.

plot abc by country
plot abc by country by month
plot abc by month

How do I restrict my grammar for the above scenario

This is my change. I get the desired result. But get the warnings.!


Query:(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) (("by" groupBy=Group)? &(condition=Condtition)? &(range=Transition)?) ;

Group:
	group+= Dimension ('by' group+=TimeGroup)? |
	group+= TimeGroup

;

I'd do that in the validator. Or use unordered groups in the grammar

e.g.

Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) ((groupBy+=Group)? &(condition=Condtition)? &(range=Transition)?) ;


Group:
	 
	
	("by" timeGroups+=TimeGroup)+ &
	
	("by" dimensionGroups+=Dimension)+
		
	
;

In my test case I get dimGroup as null. (commented the assert)


@Test
	def void testPlotMeasureByDimension() {

		val query ="plot profit by country"
		val result = parseHelper.parse(query)

		var expected =Arrays.asList("profit")

		Assert.assertEquals(result.greetings.key.getQKeyword,"plot")
		Assert.assertEquals(expected,result.greetings.measure.names)



		var groupBy=getGroupBy(result)
		//Assert.assertEquals(groupBy.get(0),"country")

	}


	def EList<Group> getGroupBy(Model model){

	return  model.greetings.getGroupBy
}

The below grammar works for me .But. Please suggest why am I getting ambiguity warning for this. How can I resolve this.


Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) ((groupBy+=Group)? &(condition=Condtition)? &(range=Transition)?) ;

Group:

	"by" ((dimGroup=Dimension("by" timeGroup+=TimeGroup)? )|timeGroup+= TimeGroup)

;

looks like you should try to understand how xtext derives the metamodel from the grammar.
and how to test

println(result.eResource.errors)
gives
[XtextSyntaxDiagnostic: null:1 no viable alternative at input 'country']

if you want to have one thing only you have to state that in your grammar havent you?
from a grammar standpoint your requirements are pain since unordered groups a ors with mult. *

therefore it would be much easyier if you would not insist to do all in grammar but move rules to the validator

you could try

Group:
	((dimensionGroups+=Dimension ("by" dimensionGroups+=Dimension)*)
	(-> "by" timeGroups+=TimeGroup)*)
	|
	((timeGroups+=TimeGroup ("by" timeGroups+=TimeGroup)*)
	(-> "by" dimensionGroups+=Dimension)*);

Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) (("by"groupBy+=Group)? &('for' condition=Condtition)? &('from' range=Transition)?) ;

.......


and look if it works when ignoring the warning

or you dont use the unordered group but do the xmath yourself


Query:
	(key=QTypekeyWord)? (aggregation=Aggregation)? (measure=MeasureList) (
		
		
		( ("by"groupBy+=Group) ('for' condition=Condtition) ('from' range=Transition) )
	|
	( ("by"groupBy+=Group)  ('from' range=Transition) ('for' condition=Condtition)  )
	|
	( ("by"groupBy+=Group) ('for' condition=Condtition) )
	|
	( ("by"groupBy+=Group)  ('from' range=Transition)  )
	|
	("by"groupBy+=Group)
	|
	(('for' condition=Condtition) ("by"groupBy+=Group)  ('from' range=Transition) )
	|
	(('for' condition=Condtition) ('from' range=Transition)  ("by"groupBy+=Group) )
	|
	(('for' condition=Condtition) ("by"groupBy+=Group)  )
	|
	(('for' condition=Condtition) ('from' range=Transition) )
	|
	('for' condition=Condtition)
	
	|
	(('from' range=Transition) ('for' condition=Condtition) ("by"groupBy+=Group)   )
	|
	(('from' range=Transition) ("by"groupBy+=Group)  ('for' condition=Condtition)  )
	
	|
	(('from' range=Transition) ('for' condition=Condtition)    )
	|
	(('from' range=Transition) ("by"groupBy+=Group)  )
	|
	('from' range=Transition)
	) ;
	
	

Group:
	((dimensionGroups+=Dimension ("by" dimensionGroups+=Dimension)*)
	(-> "by" timeGroups+=TimeGroup)*)
	|
	((timeGroups+=TimeGroup ("by" timeGroups+=TimeGroup)*
	)
	(-> "by" dimensionGroups+=Dimension)*);
	
		
	

QTypekeyWord:
	qKeyword='plot'
;

Aggregation:
	agg=('average'|'number of'|'total')
;

Condtition:
 	dimVal=DimensionValue 'as' dim=Dimension ('and' dimValue=DimensionValue 'as' dimen=Dimension)*
;

MeasureList : names+=Measure ("and" names+=Measure)*;

Measure:ID+;


Dimension:
	->dimensions+=ID+
;

DimensionValue:
	value+=ID+
;


Transition:

	dateStart=Date 'to' dateEnd=Date
;

TimeGroup:

	timeGroup=('day'|'week'|'month'|'quarter'|'year')
;
Date:
	d=Day m=Month y=Year ;


Day : INT ;
Month : 'Jan'|'Feb'|'Mar'|'Apr' ;
Year : INT ;
