Hi

A formatter generates the following code:

CREATE TABLE person (
	person_id SMALLINT PRIMARY KEY ,
	"first name" VARCHAR ( 100 ) ,
	"birth date" DATE
) ;

Is it possible to disable addition of spaces around "(", ")", ",", ";". globally for all rules? And later to add spaces for specific rules only?

Also how to use spaces for indentation instead of tabs?

have a look at the WS terminal rule (you might need to split it up in ws and nl)
and the hidden statement from the grammar and for rules

I changed my terminals from

terminal WS: ' ' | '\t' | NL;
terminal fragment NL: '\r' | '\n';

to

terminal WS: (' ' | '\t')+;
terminal NL: ('\r' | '\n')+;

I disbled my custom formatter and try to serialize XMI model (with no hidden tokens information).
I tried diferent variants:
1) Set both WS and NL as hidden for grammar
2) Set only WS as hidden
3) Set only NL as hidden
4) Set no terminals as hidden
5) Remove WS and NL from grammar at all
6) Disabe or enable formatter during serialization

But with no effect. Serializer always adds one space between all tokens
