Terence Parr e8f577e162 fix comment 2013-11-21 08:42:02 -08:00
Terence Parr 40789babf5 got tree pattern matching working on my test cases using a parser interpreter not been generated parser to compile patterns like "<ID> = <expr>;". It uses Sam's alteration to the ATN to have bypass alternatives for <expr> tags. 2013-11-20 17:54:57 -08:00
Terence Parr 2394b38995 added state to be consistent with enterRule(); most importantly, we need to set the state when we enter a recursive rule, which we are not doing at the moment. This was not a problem before because we never could directly call a recursive rule and the outer rule set the current state. Now that we are using recursive rules as start rules, we need to set the state. 2013-11-20 17:53:51 -08:00
