I want to perform a different embedded action (or generate a different
AST node) on the final rule in a list of rules.
Here's the most basic example I can think of:
identifierList:
: (Identifier -> ^(ID $Identifier))* (Identifier -> ^(OTHER
$Identifier))
;
This doesn't work because there are two alternatives when matching
just against one Identifier. So I tried making the first nongreedy
with no success:
identifierList:
: ( options { greedy = false; } : Identifier -> ^(ID $Identifier))*
(Identifier -> ^(OTHER $Identifier))
;
My actual example is a good amount lengthier and requires referencing
the rule itself in the rewrite, so solutions that require this to be
broken into multiple rules won't help me except maybe to help me
understand ANTLR better.
