Hopefully this is an easy question for someone with some Antlr skill.
Is it possible to have a rewrite rule that will convert an IN
expression to an OR expression?
E.g. from
expression IN ('FEE','FIE','FOE','FUM')
to
(expression = 'FEE') OR (expression = 'FIE') OR (expression = 'FOE')
OR (expression = 'FUM')
I have a grammer with:
equalityExpression
: relationalExpression (((EQUALS|NOTEQUALS|CONTAINS|LIKE|REGEX)^
relationalExpression)* | IN^ inList)
;
inList
: c=compoundExpr -> ^(IN_LIST $c)
;
compoundExpr
: (OPEN! ( (value (COMMA! value)*) ) CLOSE!)
;
