| | ahum.. tree construction question here is my rule: =========== compare : (shift -> shift) ( ( (LT | GT | LTE | GTE) s=shift -> ^((LT | GT | LTE | GTE) $compare $s) )* | is='is' i=identifier -> ^(IS[$is] $compare $i) | as='as' i=identifier -> ^(AS[$as] $compare $i) ) ; =========== it doesn't work... it looks like think ANTLR doesn't like my ^((LT | GT | LTE | GTE) in the tree rewriting rule. any tip on how I could rewrite this tree? |
