[antlr-interest] Is this code correct (V3.1) ?

[Foust]

Jean-Christophe,

 

I believe it would be closer to:

 

expr returns[Expr e]

@init {

Expr a, b;

e = null;

}

: ^(OR a=expr b=expr { $e = new Or($a, $b); } )

 

(Not sure about how you've defined "Expr" or "Or" - hopefully Or is a
subtype of Expr?)

Hello,


I would like to know whether this code is correct in v3.1. I am using
v3.1b2.

expr returns [Expr e]
{
Expr a, b;
e = null;
}
: ^(OR a=expr b=expr { e = new Or(a, b); } )
| etc...


or do I need to use Or($a.e, $b.e) ??

In V2 that seemed to be different...Am I right ?

Thanks for your help
Jean-Christophe
