1095 | for details. YYERROR is fine as it does not invoke this | |
1096 | function. | |
1097 | - If this state is a consistent state with a default action, then | |
1098 | the only way this function was invoked is if the default action | |
1099 | is an error action. In that case, don't check for expected | |
1100 | tokens because there are none. | |
1101 | - The only way there can be no lookahead present (in yychar) is if | |
1102 | this state is a consistent state with a default action. Thus, | |
1103 | detecting the absence of a lookahead is sufficient to determine | |
1104 | that there is no unexpected or expected token to report. In that | |
1105 | case, just report a simple "syntax error". | |
1106 | - Don't assume there isn't a lookahead just because this state is a | |
1107 | consistent state with a default action. There might have been a | |
1108 | previous inconsistent state, consistent state with a non-default | |
1109 | action, or user semantic action that manipulated yychar. | |
1110 | - Of course, the expected token list depends on states to have | |
1111 | correct lookahead information, and it depends on the parser not | |
1112 | to perform extra reductions after fetching a lookahead from the | |
1113 | scanner and before detecting a syntax error. Thus, state merging | |
1114 | (from LALR or IELR) and default reductions corrupt the expected | |
1115 | token list. However, the list is correct for canonical LR with | |
1116 | one exception: it will still contain any token that will not be | |
1117 | accepted due to an error action in a later state. | |
