[antlr-interest] Why can't I make StringTemplate to indent?

[Vinicius Durelli]

Hi all,

I have the following StringTemplate group

group RPInstr;

before(firstStat) ::= <<
<{<[beforeEnteringInstr(),firstStat]; anchor, separator="\n">}; anchor>
>>

beforeEnteringInstr() ::= "before();"

I am trying to make the first statement of a method to align with the
instrumentation code ("before();").
However, what I am getting right now is something like this:

public  int method() {
   before();
System.out.println("testing");
   System.out.println("testing again");
}

What is the proper way to indent before(); and the next statement so I get
the following?

public  int method() {
   before();
           System.out.println("testing");
   System.out.println("testing again");
}


Thanks in advance.

PS: the options that I am using in my grammar are the following

options {output=template; rewrite=true; backtrack=true; memoize=true;}
