I am using antlr 3.4 and I have the following rule:
postfix_expression
: primary_expression
( '['^ expression ']'!
| '('^ ')'!
| '('^ argument_expression_list ')'!
| '.'^ IDENTIFIER
| '->'^ IDENTIFIER
| '++'^
| '--'^
)*
;
It works almost the way I want, except in the first 3 cases of the or I
want the root to be an imaginary node with a name of my choosing instead of
the opening punctuation symbol. Is there a good way to do this?
Thanks,
-Leah
