[antlr-interest] How to use arg* when rewriting with StringTemplate

[Robert.Klaus at innovations.de]

Hi,

I would like to rewrite a language using a TreeGrammar. For this purpose
I have defined a matching rule and rewrite with a template like this:


^(ID args+=arg*) -> template(id={$ID.text}, arg={$args}) "<id> ( <arg;
separator=\", \"> )"

So what happens is that the rule "arg"'s return template is added to an
ArrayList which then is passed to the template. However "arg" does not
return a template as it does not need to rewrite something.

arg:
INTEGER
| FLOAT
| BOOLEAN
;

So what I need is the original text from each arg. When the arguments
are known, I can do it easily like this:

^(PLUS a=arg b=arg) -> template(a={$a.text}, a={$b.text}) "add (<a>,
<b>)"

How can I use this when I match arg*?

Thanks in advance,

Robert
