[antlr-interest] tree construction ?

[Chris Snyder]

This seems to do what I wanted:

 

completeExpression

      : e1=expression ( NEWLINE | SEMI | (ASSIGN e2=expression
(NEWLINE|SEMI)) -> ^(ASSIGN $e2 $e1)    )

      ;

Subject: [antlr-interest] tree construction ?

 

Hello,

 

I'm using Antlr 3 with this tree construction statement

 

completeExpression

: expression ( NEWLINE! | SEMI! | (ASSIGN^ expression (NEWLINE!|SEMI!)) )

;

 

I would like the order of the expression children of the root ASSIGN node to
be reversed. Is there a simple way to do that?

 

Thanks,

Chris
