# Racc::Parser.on_error (from ruby core) ### Implementation from Parser --- on_error(t, val, vstack) --- This method is called when a parse error is found. ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling #token_to_str. ERROR_VALUE is a value of error token. value_stack is a stack of symbol values. DO NOT MODIFY this object. This method raises ParseError by default. If this method returns, parsers enter "error recovering mode".
