QualifiedNameValueConverter related query [message #1691394]

HI All,

I have a grammar snippet as:

MyID:
	ID((".")ID)*
;

Few examples for this grammar would be: myName1.myAddress1, myName2.myAddress2.pin.

I have written a value conversion rule for this by injecting QualifiedNameValueConverter and returning the value. It works in all the sense.

Now, I have updated my grammar to:

MyID:
	ID((".")(INTRULE)?ID)*
;

INTRULE:
(INT)*
;

Now, Few examples for this grammar would be: myName1.2myAddress1, myName2.4myAddress2.pin.

i.e. after a . (dot) I need a digit. The grammar works well in the editor. But because of this QualifiedNameValueConverter conversion digits are getting removed after a . (dot).

Any suggestions here ?

Thanks in advance Smile

Arshad

Hi,

what do you mean by "conversion digits are getting removed after a . (dot)"

Hi Christian,

I have my converter code as:

@Inject
	private QualifiedNameValueConverter qnValueConverter;


@ValueConverter(rule = "MyID")
	public IValueConverter<String> converterMyID() {
		return qnValueConverter;
	}

If I have a element like myName1.2myAddress1 then this converter removes 2 from it and returns as myName1.myAddress1 and the same value will be used everywhere even if myName1.2myAddress1 is present in my editor.

Regards,
Arshad

btw why not implementing your own org.eclipse.xtext.conversion.impl.QualifiedNameValueConverter or not using QualifiedNameValueConverter if it does not fit?
